    CUTTING HEAD AND CRUSHING OF VARETAS DEL OLIVAR
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The invention, as expressed in the statement of the present specification, refers to a cutting and shredding head of olive groves that provides, to the function to which it is intended, advantages and characteristics, which will be described in detail below, which represent a remarkable improvement of the current state of the art.
    More specifically, the object of the invention is centered on a head which, adaptable to a machine tool with motor, is provided with two drums of knives capable of cutting the olive groves by grinding them, speeding up the process of Elimination of said double crochet in a single step.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of agricultural machinery, focusing particularly on the field of cutting devices and devices, and more specifically those applicable for cutting and crushing varetas of the olive grove
    BACKGROUND OF THE INVENTION
    The disheveled olive grove is an exercise that, to this day, has not been automated. There is no specific tool that performs such work with complete efficiency, and traditional and manual techniques are still commonly used.
    There are three kinds of vare removal processes; manual deburring, mechanical deburring and chemical stripping.
    The manual process is the traditional and most commonly used one, in which the person provided with a cutting tool, which is usually an ax or hoe, manually, executes the cutting action of the olive tree trunk stubs, ensuring that the cut is the closest

    to the trunk to leave no remains. It is of special relevance to mention the closeness that usually exists between the hands of the worker and the cutting blade of the tool, since with one hand the double crochet is held and with the other, tool in hand, the cut is made. It is a laborious exercise, since the working position is not the most appropriate, and after cutting the stitches it is necessary to pile them out of the olive tree to finally proceed to its definitive elimination by burning or crushing them.
    In the mechanical process, the worker is helped by a brushcutter machine with an explosion or electric motor and with the disc head or chainsaw chain adapted, cutting the stitches as close to the trunk. Although it is a mechanical process, due to the use of a machine with a combustion engine, the heads of these machines are not specifically designed for the elimination of the varetas but for other functions, such as weeding grass around the olive tree, so these heads have many inconveniences. The main drawback of this procedure is the lack of precision in the distance of the cut to the trunk and the possible wounds to the trunk.
    After making the cut, as in the manual process, it is necessary to continue with two more steps, manually collect the remains of the double crochet, grouping them out of the olive tree so that they are later crushed by means of a crusher of branches or burned, eliminating definitely the remains of the cut, so the process of removing the double crochet is laborious, entertaining and dangerous.
    Another method of removing double crochet is the chemical, based on the application of a contact herbicide, usually ammonium glufosinate because it is less harmful, using a backpack sprayer and manually applying it olive by olive. Although the system is fast and efficient, there is a significant drawback due to the systemic action of the chemical used, since if the recommended doses are not taken care of, it can harm the health of the olive tree, causing a decrease in the appearance of the varetas and even due to This systemic action, active principles of said chemical compound will enter the torrent of the tree sap, ultimately reaching the fruit that will later be ingested by consumers.
    The objective of the present invention is, therefore, to develop a specific cutting tool for this function, which avoids the described drawbacks of current systems, in a way that guarantees worker safety, ensures a tight cut and, in addition, allows

    carry out the operations of cutting and eliminating the double crochet in the same operation.
    On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other cutting and crushing head of olive groves, or invention of similar application, which presents technical, structural and constitutive characteristics equal to or similar to those presented here, as claimed.
    EXPLANATION OF THE INVENTION
    Thus, the cutting and crushing head of olive groves that the invention proposes is configured as a novelty within its field of application, since, being the characterizing details that make it possible and that distinguish it conveniently collected in the final claims that accompany this description.
    Specifically, what the invention proposes, as noted above, is a head that, adaptable to a motor, is specifically designed for cutting olive groves by crushing these, speeding up the process of eliminating The double crochet. Its main advantage is, therefore, the way of cutting and subsequent management of the cut vareta, since the varetas pass between two blade drums that it has, crushing by the impact of the blades directly on the olive tree, so that the waste they pass to the ground in small pieces cut from double crochet, used in the future to increase the organic matter of the soil and help to achieve a balanced and autonomous fertilization in the olive grove, all of which causes the process to be limited to a single step, crushing of the double crochet, accommodating and speeding up this work over time.
    To do this, the components and parts of the cutting head have been designed so that the user is only responsible for guiding the machine in the olive tree in order to supply the blades of the drums of trusses to be crushed. The machine is guided in the olive tree directly, bringing a funnel-shaped area located at the bottom of the knife drum guard to the olive varetas.
    This piece, protective of the blade drum, guides and guides the beams to the blade drums where the speed of rotation and the specific blade shape of the blades begins to crush through the end of the double crochet to the part closest to the trunk, and ejects the chips

    by the top of the blade drum protector.
    A mechanism of pinions, gears and shafts is housed on the side inside the housing, to transmit the rotation of the motor shaft to said drums.
    Inside the protective housing, the two blade drums are arranged, which are arranged radially, by way of blades, with a cutting edge placed in an arrangement of 120 ° and separated from each other enough space to intercalate those of one drum and another and allow the rotation of the two drums without leaving gaps through which the double crochet can be cast.
    The invention is designed so that it can be easily mounted so as to allow the replacement of parts without the need to disassemble all the elements of the head.
    The protector or protective housing of the blade drums has the main function of protecting the user from any possible contact with the blades and, not least, the function of orienting the olive grooves towards the blade drums to be crushed and, Once crushed, eject the chips and remnants of the double crochet through the outlet.
    The head also has an extension bar in which a transmission rod is housed, responsible for transmitting the turning force from the motor to which it is coupled to the aforementioned gear set, which is responsible for changing the direction of the transmission in 90 °.
    In case of stoppage of the blade drums, the pieces are specifically designed and arranged so that the operation of all of them continues even when said stop occurs, and that allows the correct operation of all the pieces when it has ceased.
    With all of this, the head of the invention, adaptable to a machine tool for the elimination of the olive groves, is essentially distinguished by achieving said elimination by crushing it, speeding up this process of eliminating the varetas since it is reduced to a only step in which the cutting and crushing of the double crochet in the olive tree occurs at the same time.

    For this, it comprises a system of shafts, gears, bearings, washers and nuts that rotate two drums of parallel blades that are the ones that, by impact due to the speed of rotation of the blades, crush the rods from which they are supplied .
    In addition, thanks to a conical blade protector, it is able to protect the user from possible contact with the blades, and at the same time also to direct the olive groves to the blade drums to be crushed, as well as to , once crushed, orient the remains to the outside.
    Another of the advantages of the head is that it is equipped with a safety system in which, in the event of stopping of the blade drums, the rest of the parts, both shafts and gears, continue to operate and there is no breakage of any piece.
    Likewise, the head comprises two boxes, one upper and one lower, to house the entire system of gears and bearings of the head that, advantageously, are joined together with screws, which allows the replacement of any piece in a comfortable and convenient way. fast
    Finally, the head is equipped with a transmission bar in which it houses a rod capable of transmitting the motor torque from the motor outlet to the axes of the drums, also having a structure capable of supporting the bearings in which the ends of said axes are housed in order to avoid any type of vibration and allow the proper functioning of the mechanism.
    The described cutting and crushing head of varetas del olivar represents, therefore, an innovation of structural and constitutive characteristics unknown until now, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

    It should be clarified here that the elements repeated but distinguished with letters (A, B, C), such as thymes, retaining rings, cotters, etc. they are identical or similar pieces but that are repeated in different locations in the head and that, to simplify the wording of the description and facilitate its understanding, instead of being indicated as first, second or third screw, etc. this letter has been added.
    Thus, according to these figures, it can be seen how the head in question is configured essentially from two blade drums (30) that, housed in parallel within a protective body (10), rotate in opposite directions moved by their respective axes (24, 25), when the head is coupled to a motor (not shown) through a transmission rod (2) to which the axes (24, 25) of said knife drums are linked ( 30) through a gear system, cutting and crushing the beams that catch between the blades of said knife drums (30) that penetrate through an opening provided in said protector (10) leaving the remains already crushed by another, for which, the blades are distributed radially in the drums, in the form of blades with a cutting edge,
    5
    10

    placed in a 120 ° arrangement (see fig. 5) and separated from each other enough space to allow the rotation of the two blade drums (30) without leaving gaps through which the double crochet can be cast.
    More specifically, the protector (10) of the drums has a funnel-shaped opening in its lower part that facilitates the orientation and direction of the reels to supply the blade drums (30) and, at the same time, protects the user, of any possible contact with the blades, as of the remains of the crushed that are expelled through an opening located in the upper side of the protector (10).
    On the other hand, the gear system comprises two conical sprockets (20) that change the direction of transmission 90 ° and two straight sprockets (21, 22) that rotate in opposite directions and are coupled respectively to the driving shaft (24) and to the driven shaft (25) of the blade drums (30), determining the rotation in opposite directions of these.
    The driving shaft (24) and the driven shaft (25) of the blade drums (30) are both provided with machined parallel flat faces and, as noted, are inserted inside the blade drums (30). These blade drums (30) are located between the concave-shaped spring washers (28) and drive washers (29) with recesses to fit the shafts (see fig. 2, 4, 7, 8).
    It is important to note that the gear system (20, 21, 22) and shafts (24, 25) described, has a safety system so that, in case of stabbing of the blade drums (30), no breakage is broken piece. For this, the drive washers (29) have the cylindrical hollow with two flat parallel faces, which enter the shafts (24, 25) that have the same shape, as seen in Figures 7 and 8. The drums of hollow blades (30) cylindrically are between drive washers (29) and these in turn between elastic washers (28), clamped the set of pieces by nuts (31) threaded to the axles.
    With this, when there are no problems in operation, the block of parts acts as a single piece, but in case of a break in the rotation of the blade drums (30) the safety system acts: the blade drums (30) are locked, while the drive washers (29) continue to rotate coplanarly with the shafts (24, 25) and the entire gear system (20, 21, 22), causing wear of the faces in

    contact of the blade drums (30) and the drive washers (29), but allowing the correct functioning of all parts in case of stoppage of the blade drums (30).
    The turning movement of the conductive (24) and driven axes (25) is allowed and facilitated thanks, in addition, to upper (5) and lower (6) forwarding parts that close together forming a box that houses the system of gears, and in which holes are provided that house two groups of bearings A (15) and B (26) in which said shafts (24, 25) are lodged interposing corresponding retaining rings B (14) and C (27). Also at the opposite end of both axes (24, 25) there are two bearings A (15) housed in similar recesses, specifically designed in respective upper (11) and lower (12) bearing boxes, allowing the correct operation of the mechanism and the absence of vibrations (see figs. 2, 4, 10, 11).
    These upper (11) and lower (12) bearing boxes are joined together with screws A (7) and fixed to the upper (5) and lower (6) forwards by means of structural bars (9), which are threaded to the upper (5) and lower (6) and fixed with C (13) screws to the upper (11) and lower (12) bearing housing (see figs. 10, 13). In addition, the upper (5) and lower (6) forwarding parts are also joined together by screws A (7) and B (8), all of which allow the replacement of any part quickly and conveniently.
    To extend the motor torque from the motor output to the gears, as already indicated, a transmission rod (2) is provided, which is housed in the specifically designed cavity of the transmission extension bar (3). This transmission extension bar (3), as seen in Figures 9 and 14, is designed to fix the transmission rod (2) inside with a plastic plug (4) at one of its ends and, in the opposite end, on which the motor fits, with a plastic stop (1).
    Preferably, this plastic stop (1) is designed to allow the coupling of said transmission extension bar (3) to the motor of a brush cutter or similar multifunction device through an element provided therein that incorporates an anchoring and clamping system Quick.
    The transmission rod (2), for its part, is coupled to a drive shaft (16) having a square hole in which to house the square end of said transmission rod (2).

    Said drive shaft (16) rotates housed in two bearings A (15) which, in turn, are located between another slot in the box, formed by the upper (5) and lower (6) forwarding parts, on one side thereof, from where said drive shaft (16) is coupled to the gear system.
    For this, a conical pinion (20) rotates coplanarly with the drive shaft (16) fixed with the key A (17) and retaining ring (18) as can be seen in Figure 9, making a 90 ° change of direction with the other conical pinion (20) having its axis of rotation in the driving shaft (24) the same as the straight pinion (21) joined together by the key B (19).
    The rotation of all these parts is possible thanks to the housing of the driving shaft (24) in the bearings A (15) and B (26) which, as already mentioned, rest in holes of the upper (5) and lower ( 6). The direction of rotation of the driving shaft (24) is counterclockwise and the driven shaft (25) is time for the stitches to enter through the bottom of the blade guard (10) and exit through the top as can be seen in the figure 5.
    In a homologous way to the driving shaft (24) that joins the fixed pinion (21) by means of key B (19) and conical pinion (20), it happens with the driven shaft (25), unless the straight pinion (22) is fixed to the shaft by means of key C (23) and the absence of a conical pinion, as seen in figures 8 and 9.
    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any person skilled in the art understands its scope and the advantages that derive from it.
    Likewise, it is noted that, within its essentiality, the invention may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify the fundamental.
