    AGRICULTURAL TOOL FACILITATING DEVICE FOR FACILITATING TANKING, INSTALLATION PROCESS AND AGRICULTURAL SYSTEM THEREFOR
    The present invention relates to the general field of agricultural tools and in particular tool holders intended to be interposed between a tractor and an agricultural implement, for example to facilitate the taking of rank.
    More particularly, the invention relates to a tool-holder device intended to be interposed between a tractor and an agricultural implement, said device enabling control of the positioning of said implement relative to a row of plantations independently of the position of the tractor relative to said row, said device comprising a fixed frame to be attached to the tractor, and a frame mounted movably relative to said fixed frame and intended to be attached to said tool. The invention also relates to a method of installing a tool on a tractor equipped with a tool holder device for controlling the positioning of said tool relative to a row of plantations regardless of the position of the tractor relative to said row, said device comprising a fixed frame and a frame movably mounted relative to said fixed frame, the method comprising the following steps: - attaching said fixed frame to said tractor, - said tractor is attached to said tractor. The invention also relates to an agricultural system intended to carry out agricultural work along at least one row of plantations comprising: - a tractor, - an agricultural tool such as a wine grower or a stubble cultivator, - a device interposed between said tractor and said agricultural implement, said device allowing the control of the positioning of said tool relative to the row of plantations independently of the position of the tractor relative to said row, said device comprising a fixed frame attached to the tractor, and a frame mounted movably relative to said fixed frame and attached to said tool.
    In the fields of viticulture and / or arboriculture, it is known to distribute the plantations in longitudinal rows parallel to each other. To facilitate the work of the grower and / or arborist, it is also well known to use specific equipment dedicated to the work of the vine or trees (especially fruit trees), and especially specific tools designed to be mounted on a suitable tractor (for example a tractor of small dimensions in order to be able to move between rows of vines or fruit trees) which moves along a row of plantations or between two rows of plantations. The winemaker or arborist thus has a choice of specific tools, intended to be attached to his tractor, whether "passive" or "active" tools. The "passive" tools (bumper, cultivator, stubble cultivator, etc.) are only set in motion by the movement (and speed) of the tractor and remain motionless relative to the latter.
    "Active" tools specifically adapted to the work of the vine or trees are usually equipped with a power supply plug (usually mechanical or hydraulic) to move the tool or one of its elements. (for example in rotation) relative to the tractor so as to give it an "active" character. It may be for example a lawnmower, a disassembler, brushes, grinders, or different inter-ceps tools. These "active" tools are therefore intended to be doubly connected to the tractor, to be moved by the tractor along the rows or rows of plantations, and also to receive from the tractor the energy necessary to their operation, for example by means of a gimbal connecting the tractor's power take-off to the power supply of the tool concerned or by means of hydraulic hoses connecting the hydraulic power unit of the tractor to the power take-off. supply of the tool concerned.
    These well-known known tools, are generally satisfactory to their users and can be generally installed easily on all known models of vineyard tractor or arboriculture, because of their standard character.
    However, to achieve a satisfactory result, the driving of the tractor requires an extreme skill in order to position the tool as accurately as possible relative to the (x) rank (s) of plantations. In fact, the person driving the tractor must ensure that the implement mounted on his tractor does not collide with the row (s) of planting along which (the) tractor is driving. But it must also be careful to keep the tool close enough to the row (s) of plantations to do effective work of the soil or stock (or feet). This results in increased driving difficulty, especially since the rows of plantations are generally not perfectly rectilinear, thus asking the driver for constant adjustments of trajectories that are difficult and painful.
    The driver of the tractor must therefore make great efforts, particularly in terms of concentration but also from a physical point of view, particularly because of the need to turn frequently to control the positioning of the tool generally attached to the rear of his tractor. This also results in a significant decrease in efficiency insofar as the speed of movement of the tractor is necessarily reduced in view of said adjustments of trajectories to which the driver must constantly proceed.
    The objects assigned to the present invention therefore aim to remedy the various disadvantages listed above and to propose a new tool-holder device intended to be interposed between a tractor and an agricultural implement, which while being universally compatible with the existing standard equipment, without requiring any modification of the latter, optimizes the positioning of the tool relative to the (x) row (s) of plantations subjected to the intervention of the tool.
    Another object of the invention is to propose a new tool holder device which makes it possible to correct the errors of trajectory of the driver of the tractor.
    Another object of the invention is to propose a new tool holder device which is particularly compact so as to be able to move between two rows of plantations.
    Another object of the invention is to propose a new tool holder device which is particularly adapted to receiving inter-ceps work tools.
    Another object of the invention is to propose a new tool holder device that is particularly robust, reliable while being accurate.
    Another object of the invention is to propose a new tool holder device which is particularly simple to use and safe.
    Another object of the invention is to propose a new tool holder which can indifferently be mounted at the front or rear of the tractor.
    Another object of the invention is to propose a new tool-holder device which makes it possible to facilitate and considerably secure the driving of the tractor, even during maneuvers.
    Another object of the invention is also to propose a new method of installing a tool on a tractor equipped with a tool-holder device that is universally compatible with the existing standard equipment, without requiring any modification of the latter ,
    Another object of the invention is also to propose a new method of installing a tool on a tractor equipped with a tool holder device that is particularly simple, fast and safe to implement.
    Another object of the invention is also to propose a new agricultural system intended to carry out agricultural work along at least one row of plantations which is particularly simple and safe to drive and maneuver.
    Another object of the invention is also to propose a new agricultural system which is particularly compact so as to be able to move between two rows of plantations.

    The objects assigned to the invention are achieved by means of a tool-holder device intended to be interposed between a tractor and an agricultural implement, said device allowing the control of the positioning of said tool relative to a row of plantations independently of the position of the tractor relative to said row, said device comprising a fixed frame intended to be attached to the tractor, and a frame mounted movably relative to said fixed frame and intended to be attached to said tool, characterized in that said fixed and movable frame are shaped to spare a central window allowing, regardless of the position of said mobile frame relative to the fixed frame, the passage of at least one transmission member which extends from the tractor to said agricultural tool through said device to provide power to said agricultural tool.
    The objects assigned to the invention are also achieved by means of a method of installing a tool on a tractor equipped with a tool holder device for controlling the positioning of said tool relative to a row of plantations independently the position of the tractor relative to said row, said device comprising a fixed frame and a frame mounted movably relative to said fixed frame, the method comprising the following steps: - attaching said fixed frame to said tractor, - attaching said tractor to said tractor, said method being characterized in that it further comprises a step in which is connected to said tractor, through a central window formed by said fixed and movable frame, at least one transmission member which extends from the tractor up to agricultural tool audit through said device to provide power to said agricultural tool.

Other features and advantages of the invention will become apparent and will appear in more detail on reading the description given below, with reference to the accompanying drawings, given solely by way of illustrative and non-limiting example, in which: 1 illustrates, in a perspective view from the side intended to attach to the tool, a tool holder according to the invention, said tool holder being in a neutral configuration (or centered). FIG. 2 illustrates, according to the same view as in FIG. 1, the tool holder of FIG. 1 in an extreme configuration where its mobile frame is totally shifted to the right (according to the direction of movement of the tractor, in the hypothesis where said tool holder is attached to the rear of the tractor). FIG. 3 illustrates, according to the same view as in FIGS. 1 and 2, the tool holder of FIGS. 1 and 2 in another extreme configuration where its mobile frame is this time totally shifted to the left (depending on the direction of travel of the tractor, assuming that the tool holder is attached to the rear of the tractor). - Figure 4 illustrates, in a perspective view from the side intended to attach to the tractor, the tool holder of the preceding figures in the configuration of Figure 2 (shifted right). - Figure 5 illustrates, in a front view, the tool holder of Figure 4 in the configuration of Figure 4 (shifted right). FIG. 6 is a side view of the tool holder of FIG. 5. FIG. 7 is a bottom view of the tool holder of FIG. 5. FIG. 8 is a simplified schematic representation of the space requirement and FIG. of the window formed by the frame of the fixed frame of the tool holder of Figures 1 to 7. - Figure 9 is a simplified schematic representation of the space requirement and the window formed by the frame of the movable frame of the tool holder of the figures 1 to 7, said mobile frame being shown in its two extreme positions: an extreme position on the right (that of Figure 5) shown in solid line and an extreme position on the left (dotted). - Figure 10 is the superposition of Figures 8 and 9, illustrating schematically and simplified the different positions of the tool holder of Figures 1 to 7 and the central window thus formed. - Figures 11 and 12 are detailed views of the tool holder detecting means shown in Figure 1 in a substantially similar orientation. The invention relates as such to a tool holder device, that is to say a device designed to support, carry or support an agricultural tool, and preferably a wine tool (inter-ceps tool for example) or arboreal. Said device is intended to be interposed between a tractor and said agricultural implement, thereby forming an interface between said tractor and said tool. In other words, instead of being carried directly by the tractor, said tool is carried by the tractor via the tool holder device of the invention, the latter being itself embarked on (or carried by ) The tractor. Preferably, the term "tractor" denotes a motorized vehicle intended to tow various elements, such as those commonly encountered in the agricultural field, but may also, without departing from the scope of the invention, designate any machine (motorized or not) whose main function is to tow an element, and particularly to tow an agricultural implement. Thus, without departing from the scope of the invention, the term tractor may also designate an animal coupling (for example composed of one or more horses) intended to work in the vineyards for example.
    Preferably, said tool holder can also be embarked at the front of the tractor or at the rear of the latter, by means of known attachment devices (and in particular couplings) which generally equip all the tractors, such as this will be detailed later.
    Said tool is preferably adapted to use in viticulture and / or arboriculture, that is to say to the work of plantations which are in the form of longitudinal rows parallel to each other, and which comprise vertical solid plantations, as per example of vineyards or fruit trees. In an illustrative and nonlimiting manner, said tool designates for example a "passive" tool such as a bumper, a cultivator, a stubble, etc. or an "active" tool such as a lawn mower, a disassembler, brushes, grinders, or various inter-ceps tools. However, and without departing from the scope of the invention, said tool can also be a tool used in conventional agriculture, such as a plow, a sprayer, a seeder, etc.
    According to the invention, said device allows the control of the positioning of said tool relative to a row of plantations. In other words, said tool-holder device of the invention will make it possible to position the tool it carries relative to a row of plantations, or with respect to two rows of plantations parallel to one another, such as the rows formed by vineyards or fruit trees, irrespective of the position of the tractor relative to said row. The tool holder is therefore able to position the tool it carries relative to a planting row, preferably to automatically position said tool closer to said row, without however damaging the plantings of the latter, and practically regardless of the position and trajectory of the tractor traveling in the vicinity of the said row or between the said rows of plantations.
    Advantageously, the control of the positioning of said tool by said tool holder is an automatic control which is carried out in real time, preferably to correct the defects of trajectory of the tractor relative to the (x) row (s) of plantations. Thus, thanks to the tool holder of the invention, the operation of taking rank is remarkably facilitated insofar as the small errors of trajectory of the tractor are corrected (the tractor does not need to follow very precisely the trajectory formed by the row (or rows) of plantations that it runs along, the work of the tractor driver is thus facilitated, and the forward speed of the latter can be increased to the extent that the requirements of trajectory accuracy are lower.
    According to the invention, and as can be seen in the various figures, said device comprising a fixed frame 1 intended to be attached to the tractor. Fixed frame preferably means a set of parts and / or members fixedly attached between them or between them, said assembly being itself fixed in the reference system of the tractor, that is to say fixed relative tractor. In other words, the movements of the tractor are reflected on said fixed frame 1.
    According to the preferred embodiment of the invention illustrated by the various figures, said tool holder device is attached to the tractor by a standard hitch and well known as such such as a three-point ISO coupling category 1 and 2, widely used and recognized for its robustness, reliability and safety. Such a coupling generally comprises a male part, which generally projects from the tractor, and a female complementary part which generally belongs to the tool that is to be hitched, that is to say attached, to the tractor. More specifically, each of said male and female parts is in the form of three distinct attachment points positioned in a triangle, thus defining two lower attachment points (generally parallel to the axis of the wheels of the tractors) and a point of upper attachment (or third point) located equidistant from said lower attachment points. Advantageously, said fixed frame 1 is equipped with said complementary female part of said male part of said hitch which protrudes from said tractor, so as to be able to assemble said fixed frame 1 on the tractor in an easy, safe and practical manner.
    Preferably, and as can be seen particularly in FIG. 4, said fixed frame 1 comprises a fixed upper hitching means 12 advantageously constituting said third female attachment point of said ISO 3 point hitch. Preferably, said fixed upper hitching means 12 comprises a fixed upper yoke 121 advantageously constituted by two metal plates parallel to each other and vertical, as shown in FIG. 4. According to this preferred embodiment, said means of fixed upper hitch 12 also comprises an upper pin 122 intended to correspond with two opposite holes made in each of said plates of said yoke 121. Preferably, said pin 122 is intended to be placed inside a towing hook (or hitch) protruding from the tractor to which it is desired to hook said fixed frame 1.
    Preferably, and as can be seen in particular in FIG. 4, said fixed frame 1 also comprises a fixed lower hitching means 13 advantageously constituting said two female lower attachment points of said three point ISO hitch. Preferably, said fixed lower hitching means 13 comprises, symmetrically with respect to a fixed vertical axis (FF) passing through said fixed upper hitching means 12, a fixed lower yoke 131 advantageously constituted by two metal plates parallel to each other and vertical, as illustrated in Figure 4. According to this preferred embodiment, said fixed lower coupling means 13 also comprises a lower axis 132 for corresponding with two opposite holes made in said plates. Preferably, said axis 132 is intended to be placed inside a towing hook (or hitch) protruding from the tractor to which it is desired to hang said fixed frame 1.
    Advantageously, and as can be seen in particular in FIG. 4, said fixed frame 1 comprises a first accessory support 14 intended to receive one or more accessories, such as for example an electrical box which can be intended to gather the various necessary elements. the operation of said tool holder and / or said tool (such as fuses, relays, processors, etc.). Preferably, said first support 14 is in the form of a sheet advantageously bent in angle so as to increase its rigidity which protrudes laterally from said fixed upper coupling means 12. Preferably said first support 14 has at least one plane surface substantially horizontal so as to provide a bearing surface for an electrical box (not shown in the figures) which can advantageously be fixed to said first support 14 by any fastening means (screws, rivets, etc.).
    Preferably, said fixed frame 1 also comprises a second accessory support 15 intended to receive a hydraulic distributor 22 which may be intended to supply hydraulic energy to said tool holder, as will be detailed later, or said tool, or intended to feed on the one hand said moving means 2 and on the other hand said agricultural tool energy. Alternatively, said second support 15 can also receive any other type of distributor, such as a pneumatic distributor, or even another type of component (a tank for example) and without departing from the scope of the invention. Advantageously, said second support 15 is in the form of a sheet advantageously bent to angle to increase its rigidity and whose dimensions are relatively close to said distributor 22 (or other element) that it supports and which protrudes laterally of said fixed upper coupling means 12, preferably in a direction opposite to said first support 14, Preferably, said sheet has a substantially vertical flat surface so as to provide a substantial gripping surface for said distributor 22 as can be seen on Figure 4. Said distributor 22 is then attached to said second support by any conventional means (screw, rivet, etc.).
    According to the invention, said tool holder device also comprises a movably mounted frame 3 relative to said fixed frame 1, thus constituting a movable frame 3 with respect to said fixed frame 1 and thus to said tractor. Said mobile frame 3 is then intended to be attached to said tool, which will then make said tool movable relative to said fixed frame 1 and therefore to said tractor 1, in particular for positioning said tool relative to said (s) row (s) of plantations as explained above.
    Preferably, said mobile frame 3 is intended to move over a stroke of at least 250 mm, advantageously at least 300 mm and preferably equal to 350 mm relative to said fixed frame 1. In other words, said mobile frame 3 can preferably move 175 mm on either side of its central position (or neutral position) visible in Figure 1 and wherein said fixed and movable frame 1, 3 are substantially superimposed.
    According to the preferred embodiment of the invention illustrated by the various figures, and described above where said tool holder device is attached to the tractor by a standard three-point ISO hitch, said mobile frame 3 is advantageously equipped with said complementary male part to said female part of said hitch which equips said tool, so as to be able to receive said tool, by reproducing said male part which projects from said tractor. It is thus easy and particularly safe to connect (or hitch, or attach) said tool to said tool holder of the invention, as it could be done directly on any tractor.
    Preferably, and as can be seen in particular in Figure 1, said movable frame 3 comprises an upper coupling means 32, advantageously constituting said third male attachment point of said ISO 3 point hitch. Thus, said upper hitching means 32 is fixed relative to the movable frame 3 (since mounted on the latter) but appears mobile relative to said fixed frame 1 and the tractor. Preferably, said upper coupling means 32 comprises an upper yoke 321 advantageously constituted by two mutually parallel and vertical metal plates, as shown in FIG. 1. According to this preferred embodiment, said upper coupling means 32 comprises also a tie rod 322 intended to be attached to said tool.
    Preferably, and as can be seen in particular in FIG. 1, said movable frame 3 also comprises a lower coupling means 33 advantageously constituting said two lower male attachment points of said three point ISO hitch. Preferably, said lower coupling means 33 comprises, symmetrically with respect to a movable vertical axis (M-M ') passing through said upper coupling means 32, a lower hitch 331 advantageously constituted by a hook for supporting and receiving the weight of said tool, as shown in Figure 1. In known manner as such, said lower coupling means 33 is also preferably equipped with complementary equipment, such as a safety hook 332 for locking said lower coupling means, or a setting means 333 (slides for example) for adjusting the position of each of said lower coupling hands 331 relative to the position of the means of complementary coupling of said tool.
    Preferably, as can be seen in the various figures, said fixed frame 1 and mobile frame 3 each comprise a frame, respectively a fixed frame 11 and a movable frame 31. In other words, the shape of said fixed and movable frame 1, 3 is such that it allows to form a polygonal frame. For example, said frame can form a rectangle, a square, a diamond, or advantageously, according to the preferred embodiment of the figures, a hexagon with two right angles. In other words, each of said fixed frame 11 and movable frame 31 defines a window delimited by the borders of the polygon, that is to say a hollow space, or a notch.
    Naturally, said fixed frame 1 is shaped to provide a fixed window 115 which is fixed, while said movable frame 3 is shaped to provide a mobile window 315 which is movable and which will move together with said movable frame 3. In in other words, there exists a position, said central position or neutral position represented by FIG. 1, in which said vertical axes (F-F ') and (M-M') are aligned in the same central plane and orthogonal to said fixed and movable frame 1, 3 and a plurality of other positions represented by the other figures or they are not superimposed.
    Thus, said fixed and movable windows 115, 315 advantageously make it possible to pass through these latter, and consequently through said fixed frame 1 and said mobile frame 3, various elements such as pipes, or even mobile elements such as for example transmission elements (chain, belts, cardan, etc.) intended to power the tool connected to the tractor by means of said tool holder, and this directly from the standard elements which generally equip the tractors ( PTO, hydraulic power plant, etc.).
    Preferably, said movable window 315 has a width of at least 300 mm, advantageously at least 400 mm and preferably substantially equal to 505 mm. Advantageously, this width is defined between said bushing supports 314 previously defined and visible in FIGS. 1 to 7.
    Preferably, said fixed window 115 has a height of at least 200 mm, advantageously at least 300 mm and preferably substantially equal to 436 mm. Advantageously, this height is defined between the two horizontal portions of the hexagon at two right angles, preferably formed by the fixed frame 11 visible in FIGS. 1 to 7.
    For more precision as to the displacement of the movable window 315 defined above, reference may be made to FIGS. 8 to 10 which illustrate schematically and in a simplified manner the different positions that the tool holder can take according to the preferred embodiment described by the FIG. previous figures, seen from the tractor, assuming the tool holder is attached to the rear of the tractor. Thus, Figure 8 schematically illustrates the size defined by the frame 11 of the fixed frame 1 and the window 115 formed. Figure 9 schematically illustrates two extreme positions of the frame 31 of the movable frame 3, respectively a position shifted completely to the right (the position of Figure 5 for example) shown in solid lines and a position completely shifted to the left, shown in dashed lines. Two corresponding extreme positions of the movable window 315 are thus defined and represented in FIG. 9. FIG. 10 represents the superposition of FIGS. 8 and 9, that is to say the superimposition of said fixed and movable windows 115. 315. As shown in FIG. 10, the superposition of the fixed window 115, of the mobile window 315 in its extreme right-hand position and of the mobile window 315 in its extreme left-hand position, defines a central window 6 which corresponds to the area of said previous windows that does not undergo any overlay. In particular, it is through this central window 6 that the aforementioned transmission elements can pass, since only the zone defined by said central window 6 is fixed and free from any movement during the movements of said mobile frame 3 relative to fixed chassis audit 1.
    Thus, according to the invention, said fixed and movable chassis 1, 3 are shaped to provide a central window 6 allowing, regardless of the position of said mobile frame 3 relative to the fixed frame 1, the passage of at least one transmission member which extends from the tractor to said agricultural implement through said device to provide power to said agricultural implement.
    The dimensions of each of said fixed and movable windows 115, 315 are then large enough that the displacement of said movable frame 3 does not interfere with the elements inside said central window 6. In other words, whether the displacement of said mobile frame 3 within the limits allowed by its travel and its trajectory, the dimensions of said fixed and movable windows 115, 315 are such that there is no interference between said fixed and movable chassis 1, 3, and especially between said fixed and movable frames 11, 31 and said central window 6.
    Advantageously, said tool holder device comprises a displacement means 2 connected (or attached) to said fixed frame 1 (and preferably to a fixed frame 11) and to said mobile frame 3 (and preferably to a movable frame 31). By means of displacement is advantageously meant an actuator capable of generating an output movement (for example a translation or a rotation) from an input energy (for example electrical, hydraulic or mechanical energy). In an illustrative and nonlimiting manner, said moving means 2 may comprise an electric motor, a wheel, a pulley, gears, etc. Preferably, said displacement means 2 comprises a jack and advantageously a hydraulic cylinder, that is to say a jack capable of transforming a hydraulic pressure into a linear displacement in the form of translation. In a manner known per se, a jack is generally composed of at least one body 21 (or chamber), inside which a piston (not shown in the figures) circulates, piston to which a rod 23 is attached. the frame of a double-acting cylinder, the pressure of the fluid sent on one side or the other of the piston then allows alternately and respectively to exit the rod 23 of the cylinder and to enter the latter.
    According to the preferred embodiment illustrated in FIGS. 1 to 7, said displacement means 2 comprises a double-rod cylinder 23. In other words, said displacement means 2 comprises two rods 23 protruding from the body 21 of said piston cylinder. opposite way, while being located on the same axis and being attached to the same piston. Thus, the movement of the piston of the jack will then generate the immediate and simultaneous movement of the two rods 23.
    Still according to this preferred embodiment, each of said rods 23 is attached to the mobile frame 3, and preferably at a lower angle of the movable frame 31 as can be seen in Figures 1 to 7, while the body 21 of the cylinder is attached to the fixed frame 1 and preferably to the lower central part of the fixed frame 11. This therefore results in a displacement of said movable frame 3 in a translational movement. Preferably, said fixed and movable frames 11, 31 are parallel to each other and mounted substantially perpendicular to the trajectory of the tractor, the latter being substantially parallel to the (x) row (s) of plantations. In other words, the translational movement imparted by said jack is therefore along an axis substantially perpendicular to said planting row.
    Advantageously, said tool holder device further comprises a guiding means 4 whose function is advantageously to guide said movable frame 3 and particularly said movable frame 31 during the displacement of the latter under the effect of said displacement means 2, and this to facilitate and guide the movement of the latter relative to said fixed frame 1 and particularly to said fixed frame 11. Like the displacement means 2 described above, said guide means 4 is advantageously connected or attached on the one hand to said frame fixed 1 (and preferably to the fixed frame 11) and secondly to said movable frame 3 (and preferably to the movable frame 31).
    Preferably and as can be seen in the preferred embodiment illustrated in FIGS. 1 to 7, said guide means 4 comprises a slide 43 intended to move (in this case to slide) inside a ring 41, so as to provide a sliding pivot connection. Preferably, said guide ring 41 is integral with said fixed frame 1, for example advantageously fixed between said vertical plates of said fixed upper fastening means 12, as can be seen in FIGS. 1 to 7, whereas said slide 43 is attached to said movable frame 3, and more particularly to said movable frame 31. For example, said slider 43 may comprise at each of its ends a sleeve 34 fixed to said slider 43 by conventional means (a pin for example) so as to be able to be fixed to said movable frame 31, preferably via a socket support 314 similar to that illustrated in FIGS. 1 to 7 and fixedly mounted with respect to said movable frame 31 and to said bushing 34. Preferably, said support socket contributes to the rigidity of said mobile frame 3 by connecting the upper part of said movable frame 31 and the lower part of said frame re movable 31 as illustrated in Figures 1 to 7. Advantageously and symmetrically to a movable central vertical axis (M-M ') passing through said upper coupling means 32, said movable frame 31 comprises two socket supports 314 each connected to a bush 34, each of said bushings 34 being connected to an end of said slider 43.
    Preferably, said guide means 4 is disposed parallel to said double-rod cylinder 23 described above and centered with respect to the latter, in particular with a view to facilitating guiding and moving said movable frame 31 relative to said fixed frame 11 and in particular avoiding the arching phenomena.
    Alternatively, it is quite possible without departing from the scope of the invention, that said guide means 4 is disposed in another way with respect to said jack, or possibly that said guide means 4 is integrated with said moving means 2. even be constituted by the latter.
    Thus, according to the preferred embodiment described above and visible in FIGS. 1 to 7, said tool holder device comprises a displacement means 2 and a guiding means 4 each of said displacement means 2 and guiding means 4 being connected on the one hand to said fixed frame 1 and on the other hand to said mobile frame 3 so as to move said movable frame 3 in a translation movement along an axis substantially perpendicular to said planting row.
    In the preferential case described above wherein said fixed frame 1 comprises a first support 14 a second support 15, the shape, the arrangement of the latter and the accessories they support {and in particular the hydraulic distributor 22) then offer everything a remarkable protection of said slider 43 against the external elements that could possibly fall on the latter and damage or impede its sliding, such as rain, snow, leaves, etc.. Indeed, by projecting laterally on either side of said fixed upper hitching means 12, said first and second supports 14, 15 are located above and in line with said slide 43, thus protecting it from certain aggressions. exterior.
    Advantageously, said tool-holder device comprises at least one detection means 5 of said row of plantations, as can be seen in FIGS. 1 to 7. In other words, said tool-holder device is capable of detecting autonomously , and preferentially in real time and automatically said row (s) of plantations. Preferably, said detection means 5 is then intended to automatically control said moving means 2 in order to position the tool carried by the tool holder with respect to a planting row, or with respect to two rows of plantations parallel to each other, such as rows formed by vineyards or fruit trees, regardless of the position of the tractor relative to said rank, as explained above. More precisely, said detection means 5 will then control said moving means 2 as a function of the detection or the non-detection of the planting row, as will be detailed hereinafter.
    According to a preferred embodiment, said detection means 5 is mounted on an angle of the frame 31 of said mobile frame 3, and advantageously on a lower angle, as can be seen in FIGS. 1 to 7.
    Preferably, said tool-holder device comprises two detection means 5 arranged at the two lower corners of said movable frame 3, or more precisely at the two lower angles of said movable frame 31 and in a manner symmetrical with respect to said movable vertical axis (M-M ' passing through said upper attachment means 32.
    Preferably, said detecting means 5 comprises a feeler 51 intended to come in point contact with said row of plantations, as can be seen in FIGS. 1 to 7. Advantageously, said feeler 51 comprises a rod bent at 90 ° and each of which lengths is greater than 200 mm and advantageously greater than 250 mm. In other words, said feeler 51 is in the form of a substantially rigid rod having the shape of an L. Such a shape and length of probe 51 advantageously advantageously makes it possible to detect the row of plantations more easily and more linearly, to the extent that in view of its length, the probe 51 is unlikely or even no chance of falling between two vines or between two tree trunks. In other words, thanks to the particular length of said probe 51, the measurement is smoothed and control of said improved tool holder thus avoiding too many round trips between two positions.
    Preferably, said detection means 5 comprises a sensor plate 52 integral with said probe 51. In other words, when said feeler 51 comes into contact with said row of plantations, said feeler 51 will move, preferably around a pivot 55, in a circular arc path (pivot connection). Therefore, said sensor plate 52 is also rotated about said pivot 55.
    Advantageously, said detection means 5 also comprises a motion sensor 351 mounted on a probe support 54 integral with said mobile frame 3 and intended to detect the movement of the feeler 51 (and more particularly the movement of said sensor plate 52) when this last is in punctual contact with said row of plantations. Preferably, said detection means 5 also comprises an automatic return means 53, such as for example a spring, in order to maintain and return to the rest position, that is to say in the position in which said feeler 51 is not in contact with said row of plantations, said feeler 51 and said sensor plate 52. Advantageously, said detection means 5 further comprises a device for adjusting the automatic return means 531, such as a screw nut system, for example, allowing to adjust the force of the automatic return, for example according to the speed of movement, the size of the trunks or vines, the wear of the mechanism, etc.
    Preferably, said motion sensor 351 comprises an inductive sensor capable of detecting the presence or absence of said sensor plate 52. Advantageously, said motion sensor 351 is a normally closed sensor, that is to say that it is designed to send a signal when it does not detect said probe plate 52. In fact, if said inductive sensor does not detect said sensor plate 52, it means that the latter has set in motion following a rotation said feeler 51, itself linked to a contact between said probe 51 and said row of plantations.
    Preferably, said detection means 5 is connected to said mobile frame 3, and more precisely to said mobile frame 31 via a device for adjusting the detection means 56, as can be seen in detail in FIGS. 11 and 12 More specifically, said feeler support 54 is fixed to said adjustment device which is itself linked to the mobile frame 3, preferably via a lockable slide connection.
    Advantageously, said adjustment device 56 makes it possible to move and then immobilize said detection means 5 with respect to said mobile frame 3, in particular in order to allow the user to perform the positioning and centering step required beforehand. the use of the tool holder, as will be detailed later. In other words, said adjustment device makes it possible to move away from or on the contrary to bring said detection means 5 closer to said mobile frame 3, for example by means of a rack or slide 562, or by any other means. moving and fixing. Preferably, said rack or slide 562 comprises locking means (not shown in the figures) in order to immobilize the latter in the position chosen by the user.
    In the preferred case where said tool holder comprises two detecting means 5 arranged symmetrically with respect to the movable vertical axis (M-M ') passing through the upper coupling means 32, said two detecting means 5 are perfectly identical and advantageously comprise the same architecture, and advantageously the architecture described above. Thus, thanks to said detecting means 5, as well as to a particularly simple control assembly (not shown in the figures) but which can advantageously be integrated in said electrical box positioned on said first support 14, i! it is possible to simply, quickly and effectively control the positioning of said mobile frame 3, and therefore said tool that it supports, relative to (x) row (s) of plantations.
    The operating principle of the automatic and real-time positioning of said tool, in the case of use between two rows of plantations, thanks to the tool holder device of the invention will now be described in detail. Firstly, after having attached said tool holder to the rear of its tractor and the tool to the tool holder, the user, that is to say the tractor driver (usually a winemaker or an arborist ), positions the tractor and therefore the tool holder (and therefore the tool attached thereto) substantially in the middle of the space defined between said rows of plantations (for example between two rows of vines). Then, the user will adjust the position of each of the detection means 5 so that each of said feelers 51 comes flush each of said rows of plantations, but without touching them. To this end, the user uses said adjustment devices 56 in order to exclude or bring closer each of said detection means to said mobile frame 3. This operation then makes it possible to determine the central position or neutral position around which said mobile frame 3 will move. Then, the user can begin to move the tractor forward and thus start the work of the land or plantations he wants to do. As the tractor moves and small deviations in its trajectory and / or plantation planting defects, the tool-holder device will then be brought closer to one of the two rows of plantations. , for example from the left row. Therefore, the probe 51 located at the lower left corner of said movable frame 31 will then come into contact with the row of plantations on the left, which will cause the rotation of said feeler 51 around the pivot 55, as well as the rotation of the probe plate 52 secured to said probe 51. The motion sensor 351 will then detect the absence of said sheet 52 and send a signal to the tool holder means that the latter is too close to the row of plantings left. In response, said tool-holder device will then actuate said moving means 2 in the opposite direction, that is to say to the right, in order to direct said movable frame 3 towards its extreme position shifted to the right, as one can for example see it in Figures 2, 4 and 5. Specifically, the distributor 22 will send oil into the left chamber of the cylinder to move the rods 23 to the right. The movement of said moving means 2 (and consequently of said mobile frame 3) continues as long as said sensor 351 does not detect said sheet again 52, that is to say as long as said feeler 51 is in contact with said row. planting left. In other words, as soon as the signal of said sensor 351 ceases, this means that said sheet 52 has returned to its rest position (under the effect of the automatic return means 53) and that consequently the feeler 51 is no longer in contact with said row of plantations. Therefore, the tool holder (and therefore the tool) is correctly positioned and it is necessary to stop the movement of said moving means 2 and said movable frame 3. The tool holder therefore stops supplying said displacement means with oil. the mobile frame 3 stops. Naturally, when the row of plantations on the right is approached, it is a perfectly similar and symmetrical operation that is implemented, which is therefore not necessary to detail here.
    In a particularly advantageous manner, said detection means 5 is returnable by 180 ° so as to adapt to the direction of movement of said device with respect to said rank of plantations. In other words, it means that it is possible to position said tool holder at the rear of the tractor, as described above but also at the front of the tractor. Indeed, as explained above, the particular shape of said feelers 51 visible in FIGS. 1 to 7 has been particularly studied to smooth the movements of movement of said mobile frame 3 while remaining in contact as long as possible with each of the feet or vines from the row of plantations. But this form of L imposes a single direction of movement, that in which it is the right angle of the probe 51 which comes into contact first with the obstacle (the foot or the vine). Indeed, if this is not the case, the free end of the probe rod 51 may enter between two feet or two vines, get stuck and thus deform said feeler 51 or break. Therefore, the remarkable feature defined above that it is possible to turn 180 ° about a vertical axis said detection means 5 allows to use the tool holder indifferently at the rear of the tractor (c ') ie by pulling the tool) or at the front of the tractor (ie by pushing the tool). The modularity of said tool-holder device is therefore considerably increased. Thus, Figures 1 to 7 illustrate each of said moving means installed in an inverted position. More precisely in FIG. 1, it can be seen that the right-hand detection means 5 is installed so as to be able to mount the tool-holder device at the rear of the tractor and is able to come into contact with a row of plantations on the ground. right, while the detection means 5 is installed in the opposite direction (returned 180 °) so as to mount the tool holder device at the front of the tractor and is adapted to come into contact with said row of plantations on the right.
    In order to allow easy, fast and safe reversal of said detecting means 5, said adjusting device 56 advantageously comprises an opening fixing slot 561, as can be seen in FIG. 12. Thus, by virtue of said fixing slot 561, it is possible, by means of standard fasteners (not shown) such as a screw / nut device for example, to fix said detecting means on either side of said adjusting device 56, and so on. to be able to turn 180 ° said detection means 5.
    Advantageously, said tool-holder device is intended to move between a working position and a transport position respectively according to which said agricultural tool is intended to work and is not intended to work. In other words, said tool holder comprises a working position in which it is intended to be located along the row of plantations or between two rows of parallel plantings. In this working position, said tool holder is then lowered and located at a relatively low height of the ground in which it allows the good work of the tool that it supports. When the tool holder is in this working position it is caused to move from left to right said mobile frame 3 according to the principle detailed above. But said tool holder also includes a transport position in which it is not intended to be located along the row of plantations or between two rows of parallel plantations. On the contrary, in this transport position, said tool holder is then raised and located at a relatively high height of the ground in which it allows the tool it supports not to be in contact with the ground. This transport position (or raised position) then facilitates transport, maneuvering, maintenance, etc. tool and tool holder, while remaining attached to the tractor. The transition from the working position to the transport position is preferably effected via the hitch of the tractor which is movable in height, on the order of the driver.
    Preferably, said tool holder device comprises a lifting sensor 124 intended to detect said transport position, in particular in order to be able to trigger various actions and / or alerts related to the change of position of the tool holder, such as for example the automatic stop of the tool carried by the tool holder (in the case where said tool is an active tool, moving), or the automatic refocusing of the tool holder, as will be detailed later.
    Preferably, said lift sensor 124 is mounted on a lifting sensor support 123 such as that visible in FIG. 4. Advantageously, said sensor support 123 is then secured to said fixed upper coupling means 12 and preferably to said upper clevis 121. Advantageously, said sensor support 123 comprises a fixing slot for adjusting, by means of a conventional fastening device (a screw nut device for example), the height of said lifting sensor 124, and this to allow the user to better adjust the precise moment when said sensor 124 will detect the change of position of the tool holder, in particular according to the technical characteristics of his tractor and / or said tool carried by the tool holder.
    Advantageously, said lift sensor 124 is an inductive sensor capable of detecting in the vicinity of it the presence of a metallic element and preferably the presence of the coupling tie of the tractor to which said fixed upper hitching means 12 is connected. Indeed, the presence in the detection field of said sensor 124 of this drawbar means that the tool holder is in the transport position (raised) and not in the working position (lowered), as illustrated in FIGS. at 7.
    Advantageously, said tool holder device comprises at least one moving frame displacement sensor 311 intended to detect the displacement of said movable frame 3 relative to said fixed frame 1, as can be seen in particular in FIG. 4. Preferably, said displacement sensor of the mobile frame 311 is mounted (that is to say on board) on said mobile frame 3, as illustrated for example in FIG. 2. Advantageously, said displacement sensor 311 is mounted on a sensor support 312 made plate and having a fixing slot for adjusting the positioning of said sensor 311, for example by means of a conventional fastening device (nut screw device for example), in particular according to the precision sought by the user. Preferably, said sensor support 312 is fixed to said mobile frame 3, as can be seen in Figure 2 for example.
    Advantageously, said displacement sensor 311 is an inductive sensor capable of detecting in the vicinity of it the presence of a metallic element and in particular the presence of a metal element advantageously belonging to said fixed frame 1. Preferably, said displacement sensor 311 interacts with said first or second accessory support 14,15, in particular by detecting the presence of said sheet in its detection field, as will be detailed later.
    Preferably said tool holder comprises two moving frame displacement sensors 311 as described above and mounted symmetrically with respect to said movable vertical axis (M-M '). In this case, and particularly advantageously, each of said displacement sensors of the mobile frame 311 will then detect one of said first or second support 14,15 described above. Indeed, the particular shape of the latter has been studied in particular to interact with said sensors 311 accurately so as to be in the detection field of said sensors only when said mobile frame 3 is in a position other than the centered position (or neutral position).
    The operation of said tool holder device during the transition from its working position to its transport position will now be detailed. When the tool holder is in its working position and the latter moves from left to right as the data provided by the detection means 5 according to the operating method described above, the movements of said moving frame 3 relative to said fixed frame 1 are followed by said displacement sensors 311.
    More specifically, when said movable frame 3 is in a centered position (or neutral position), it is substantially aligned with the fixed frame 1 as can be seen in FIG. 1. In this position, no obstacle is located in the field. detection of said sensors 311 as can be seen in Figure 1. In particular, the left sensor 311 is beyond said first support 14 and the right sensor is facing a cut in said second support 15. On the other hand, when the mobile frame 3 moves to the right, for example to tend to assume the position illustrated in FIG. 2, the right sensor 311 will be beyond said second support 15 (and consequently detect nothing ) while the left sensor 311 will be facing said first support 14. In other words, when the mobile frame 3 moves to the right (according to Figure 2), the left sensor 311 is in its fieldThe said left sensor 311 will then send an electrical signal to the tool holder to indicate that the movable frame 3 has left its neutral position and is shifted to the right. This position corresponds to a perfectly normal working position of said tool holder where the latter corrects a defect of trajectory and / or misalignment of the tractor relative to the (x) rank (s) of plantations, as has been explained previously.
    Imagine now that the tractor arrives at the end of the row of plantations and must make a U-turn to position itself in the next row. The driver, once out of the row will then raise the tool holder to make it leave his working position and make it reach its transport position to be able to maneuver easily and safely. The lifting sensor 124 will then detect the presence in its detection field of said tractor coupling tie and send its signal to the tool holder device. The latter will then compare the information from said lifting sensor 124 and displacement sensors 311: In this case, in this example, the mobile frame 3 is shifted right while the tool holder is in the transport position (position up). This is a configuration that is not normal, or that can be dangerous. Indeed, if the movable frame 3 remains shifted to the right, the latter will not be correctly positioned at the next take of rank (that is to say when the driver will position his tractor in the center of the next row), but this offset can also be dangerous during maneuvers and / or transport inasmuch as the movable frame 3 is not centered with respect to the tractor and thus exceeds more than one side of the other (in the occurrence on the right), which entails a significant risk of hanging elements (trees, panels, pedestrians, etc.) located on the side of the road, for example.
    Given this situation, the tool-holder device will then automatically and immediately move said displacement means 2 to the left in order to refocus said mobile frame 3. In other words, said distributor 22 will then send the oil in the right chamber of the piston to shift the rods 23 to the left. The movement of said moving means 2 is stopped as soon as said displacement sensor 311 no longer detects said first support 14 in its detection field, thus indicating that the mobile frame 3 has regained its centered (or neutral) position. Thus, the safety and the ease of maneuvering and / or transport are remarkably improved by said lifting and displacement sensors 124, 311 insofar as the information of said lifting sensor 124 and displacement sensor of the movable frame 311 make it possible to control automatically said moving means 2 so as to ensure an automatic refocusing of said movable frame 3 relative to said fixed frame 1 in the transport position.
    Thus, according to this particular advantageous embodiment, there are at least two elements that can trigger a movement of said mobile frame 3: either the information provided by said detection means 5 or the information provided jointly by said lifting and displacement sensors 124 , 311. Optionally, and without departing from the scope of the invention, a third trigger mode, which would be a manual movement ordered by the user is obviously possible. The invention also relates as such to a method of installing a tool on a tractor equipped with a tool holder device for controlling the positioning of said tool relative to a row of plantations regardless of the position of the tractor relative to said rank, said device comprising a fixed frame 1 and a movably mounted frame 3 relative to said fixed frame 1, as previously described.
    According to the invention, said method comprises the following steps: - said fixed frame 1 is attached to said tractor, preferably by means of said fixed upper and fixed lower linkage means 12, 13, said tractor is attached to said tractor, preferably by means of said upper and lower coupling means 32, 33, - is connected to said tractor, through a central window 6 formed by said fixed and movable frame 1, 3, at least one transmission member (such as a universal joint or a hydraulic hose) extending from the tractor to said agricultural implement through said device to provide power to said agricultural implement. The invention also relates as such to an agricultural system for carrying out agricultural work along at least one row of plantations comprising: - a tractor, - an agricultural tool such as a wine grower or a stubble cultivator, - a device interposed between said tractor and said agricultural implement, said device enabling control of the positioning of said implement relative to the row of plantations independently of the position of the tractor relative to said row, said device comprising a fixed frame 1 attached to the tractor, and a mobile mounted chassis 3 relative to said fixed frame 1 and attached to said tool - at least one transmission member (such as a gimbal or a hydraulic hose) for supplying power to said agricultural implement which extends from the tractor to said agricultural implement, said transmission member passing through a central window 6 formed by said fixed and movable frame 1, 3, whatever the position of said mobile frame 3 relative to the fixed frame 1.
