    533 800 For example, WO 85105246 discloses a seed drill having two rows of bill discs arranged one after the other as well as a packing roller running after them, which consists of a number of packing wheels arranged next to each other. The individual packing wheels are separately height-adjustably suspended so that a certain ground adaptation can be achieved when crossing longitudinal waves. Although the achievable ground adaptation is limited in contoured ground waves with a large surface or hanging edges due to the limited height mobility of the suspension, there is also a change in the compressive force along the height adjustment path of the pack wheels, so that a large uneven surface occurs.
    Based on this, the object of the present invention is to provide an improved agricultural machine of the type mentioned, which avoids disadvantages of known technology and advantageously further develops the latter. In particular, an improved ground adaptation with even distribution of the abutment force must be achieved, even in the case of contoured longitudinal waves with a large surface area, without this being achieved at the cost of a more difficult transportability of the machine.
    This object is achieved according to the invention by an agricultural machine according to claim 1. Preferred embodiments of the invention are subject to the dependent claims.
    It is proposed that the pivotability of the pivot frame around the horizontal axes pointing in the direction of travel is also used for ground adaptation and this pivotability is designed so that the work units pivotally suspended via the pivot frame, in addition to their working position arranged for even ground, are pivotable downwards in a further submerged position, in order to achieve a negative ground adaptation, for example at hanging sides inclined to the side and ground wave sides, respectively. According to the invention, the swing frames for ground adaptation in working mode are kept pivotable in an extended suspension position, in which tool parts lying further to the side outwards are deeper than further inwards towards the track center, tool parts, a control device for mobility control of the lifting device in working mode being arranged. The lifting device, by means of which the swivel frames with the working tools arranged thereon can be lifted into the transport and turning position, respectively, is not locked in the lowered working position of the swivel frames, but movably coupled 533 800, so that the swivel frames can swing up and down like bird wings, at crossing of said ground contours. Due to the extensibility downwards in addition to the neutral position for even ground surfaces, intended tillage is ensured in the edge areas of the machine width located on the side, even when crossing dome-shaped, convex longitudinal ground contours. The effective height adjustment over the entire working width is especially important for seed drills, in which even small errors in the height of the working tools result in insufficient sowing and, for example, for the seed beetles in a height corridor a few millimeters wide.
    The area of pivotability of the work units arranged to the right and to the left of each other is in working mode preferably not only limited to extensibility downwards, but extends on both sides of the neutral position, which the work units must occupy for level ground. Preferably, the lifting device allows a pivoting of the pivot frames from a neutral position, in which the working tools stand on level ground evenly across the working width, in both directions so that the pivot frames are pivotable between a raised pivot position via said neutral position downwards in the aforementioned extended suspension position and vice versa. achieve both a positive ground adaptation of the sides ascending on the side of longitudinal groove-shaped ground depressions as well as a negative ground adaptation at dome-shaped arched longitudinal ground waves.
    In order to achieve an even distribution of the abutment force and an even ground pressure over the entire working width, the swing frames in a further development of the unit are provided with a ground pressure device 26, by means of which a ground pressure device 26, compressive force can be exerted on the pivot arms and the work units located on the side, up and down pivotable. Correspondingly, the work units located on the side are not only pressed against the ground with their own weight, but can also lead in a further part of the remaining machine weight on the work units located on the side and are diverted to the ground via these.
    Preferably, the ground pressure device then comprises a resilient prestressing device, by means of which a prestressing force directed towards the ground can be exerted on the working units located on the side, over an at least substantial part 533 800 4 of the turning area of the swing frames provided for ground adaptation operation.
    The flexibility thus ensures a directed ground compressive force of the working units located on the side over a sufficiently large part of the turning area, preferably over the entire turning area arranged for the ground adaptation.
    In particular, the prestressing device also completes a downwardly directed compressive force in the overstretched and even the overstretched suspension frame of the pivoting frames located on the side, which ensures work according to the regulations with the compressive force arranged there, even when the working units located on the side travel downwards for ground adaptation.
    Preferably, the ground compressive force is variable. By means of an adjusting device, the desired prestressing force or ground pressure force can be adapted to existing operating parameters such as soil moisture, soil evenness or the like.
    The ground pressure device can thus in principle be differently designed. For example, a mechanical spring comes into question, which in the aforementioned neutral working position has a certain preload, in order to push and pull the work units downwards, respectively. In a preferred further development of the invention, however, the ground pressure device is hydraulically and / or pneumatically operating. In particular, the ground pressure device may have a pressure medium cylinder and a pressure medium accumulator, from which said pressure medium cylinder can be filled with a bias pressure during operation. On the one hand, such a pressure medium actuation of the biasing device allows a simple control of the desired biasing force, on the other hand, a larger adjustment path can be easily realized. In order to control the prestressing pressure, in particular a pressure control valve belonging to the pressure accumulator and / or a pressure limiting valve can be provided, by means of which the prestressing pressure given to said pressure medium cylinder can be controlled or limited.
    In particular, the ground pressure device for lifting the work units located on the side can be integrated in the lifting device, so that said lifting device, so to speak, performs a double function. While on the other hand the working units located on the side can be lifted up in the transport and turning position, on the other hand the working units located on the side can be pushed or pulled towards the ground with the desired downward pressure. In particular, the lifting device may comprise at least one double-acting hydraulic cylinder, the lifting chamber of which is connectable to a hydraulic circuit of the lifting device and the lowering chamber of which is connected to the aforesaid pressure accumulator. Alternatively or in addition, the said lowering chamber can also be connected to the hydraulic circuit of the lifting device, so that the lowering movement can also be operated with hydraulic pressure from the hydraulic circuit, whereby possibly also the bias can be provided over corresponding control of the hydraulic pressure in the hydraulic circuit. In this context, for example, the tractor-hydraulic circuit can be used, the pressure of which can be set by means of the said control and regulating means, respectively. However, the aforementioned solution with a pressure accumulator is preferred, which in this case provides an independent solution for achieving the desired ground compressive force, which allows normal operation of the agricultural machine even in tractors which do not have such an adjustable hydraulic circuit.
    The mentioned work units arranged to the right and left of each other can in principle constitute the only work units at Iantbruksmaskinen. In a preferred further development of the invention, however, the agricultural machine has, in addition to the two work units located on the side, at least one, between them, viewed opposite the direction of travel, in the middle work unit, which is anchored by the work units arranged on the right and left. Thus, the total working width of the machine can be distributed evenly on the mentioned work units, so that in the case of a work unit located in the middle and two work units located on the side, each work unit has a width of about 25 to 40% of the total width, especially about one third of the total width.
    In such a design with a work unit located in the middle and two at the work units located on the side, the pivotability of the work units located on the side is preferably designed so that the work units located on the side are stretched with their tools compared to the center work unit. are arranged deeper and / or sloping to the side from the working tools of the working unit in the middle, so that the entire working device has a total of 533,800 across the entire width and has a convex and / or bridge-shaped tool abutment surface.
    In particular, the working device in the said extended hanging stand may comprise a reasonably evenly located area in the middle as well as two hanging wings located on the side.
    To enable a further adaptation movement within a work unit, the pivot frames and / or the support frames of the work unit located in the middle fl are transversely arranged work tools arranged next to each other, which are individually or in groups suspended vertically on pivot frames or support frames. For example, in the case of packing rollers, these can be divided within each work unit into pack your packing wheels and packing roll sections, which are preferably height-adjustable individually or in pairs, so that a detailed, particularly punctual ground adaptation is possible, for example when crossing rocks or narrow gutters or ground faults. . In the case of bill discs, these can be individually or possibly also in pairs mounted height-adjustably on the frame through the rockers which are pivotable about transverse axes. Correspondingly, the work units enable two steps of ground adaptation. On the one hand, large ground contours can be smoothed out by pivoting movements of the swing frame and thus the work units together, while on the other hand small contoured ground faults can be leveled out by individual height movements of individual tool parts within a work unit or even within several work units.
    The invention is explained in more detail below with the aid of a preferred embodiment and associated drawings.
    Fig. 1 is a schematic perspective view of a seed drill according to an embodiment of the invention.
    Fig. 2 is a schematic side view of the seed drill in Fig. 1.
    Fig. 3 is a schematic frontal view of the seed drill in the preceding gures according to an advantageous embodiment of the invention, the working units located on the side being shown in a neutral working position on level ground.
    Fig. 4 is a front view of the seed drill corresponding to fi g 3, the side work units being shown in a stretched suspension position for ground adaptation on sideways sloping driveways. 533 800 Fig. 5 is a frontal view of the seed drill corresponding to fi g 3 and 4, the work units located on the side being shown in an upwardly curved working position for ground adaptation at sidan anchors rising on the side in overall gutter-shaped driveways.
    The seed drill 1 shown in the drawings comprises a machine frame 2, which carries a seed container 3, from which seed can be laid in the ground in a well-known manner through seed lines 4. In the embodiment shown, the machine frame 2 can be mounted on a tractor (not shown) by a drawbar 5 .
    The machine frames 2 then carry various tillage tools. For example, the front area may comprise tillage tools 6, in the form of car discs 7 and a packing roller 8 consisting of a plurality of adjacent packing wheels 9, which are arranged in rows one after the other. The sowing rail 10 can be arranged in the rear area of the machine frame 2, whereby fi g 1 shows in rows arranged seed beetles, ground pressure wheels as well as harrows, compare fi g 1 and Fig. 2.
    As fi g 3 to 5 show, the machine frame 2 is divided into fl your frame parts, which are pivotable and foldable relative to each other. In the embodiment shown there is then a central frame part 11, which is connected to the aforementioned drawbar 5, as well as two pivoting frames 12 and 13 projecting on the side of said central part 11, each of which is connected around a lying approx. direction of travel pointing pivot shaft 14, 15 in the area with the side edges of the aforementioned center part 11 located in the middle, so that the pivot frames 12 and 13 located on the side can pivot upwards and fold up, respectively.
    The two pivot frames 12 and 13 located on the side thus, like the frame part 11 located in the middle, each carry a work unit 16 and 17, each of which may comprise the aforementioned tillage tools 6. 1 g 3 to 5, the packing wheels 9 of the packing roller 8 can be seen, which are suspended on the frame part 11 located in the middle and the pivot frames 12 and 13 located on the side, respectively, the soil cultivating tools 6 suspended on the side pivot frames 12 and 13 can pivot up and down together with the said pivot frames 12 and 13, as shown in a comparison of Figures 3, 4 and 5.
    As lifting device 19 for lifting the working units 16 and 17 located on the side, in the embodiment shown pressure means cylinders 20 and 21 533 800 are arranged, which are on the one hand connected to the pivot frames 12 and 13 and on the other hand to the centrally located the frame part 14 and grip, respectively, grip a support part connected thereto. The pressure medium cylinders 20 and 21 are operated from the tractor by a pressure circuit 22 indicated in FIG. 3. In addition, the chambers of the pressure medium cylinders 20 and 21, which cause a lowering of the work units 16 and 17, are connected to a pressure accumulator 23 provided with an adjustable pressure relief valve 24. that the work units 16 and 17 are at least pressed downwards with a desired adjustable biasing force in the submerged working layer.
    Said pressure accumulator 23 can thus be designed as a diaphragm accumulator. When the machine is unfolded, said pressure means cylinders 20 and 21 press the work units 16 and 17 located on the side against the ground with an adjustable pressure. When this adjustable pressure is reached, the pressure relief valve 24 shuts off the circulation, so that from this point on the system works shut off with the built-in diaphragm accumulator. In this way the following mode of operation is achieved: When crossing a dome-shaped longitudinal hill, the edges of which slope downwards to the sides to the left and right, the swing frames 12 and 13 give way and extend, as shown in fi g 4, i.e. the side swing frames 12 and 13 together with the tillage tools 6 suspended thereon hangs, so to speak, sloping downwards like wings, so that the tillage tools 6 arranged further out occupy a deeper position than the tillage tools 6 located further in. This can in particular result in the in fi g 4 shown the configuration in which the tillage tools 6 arranged on the central frame part 11, in particular the packing wheels 9, assume a sensory function, while the laterally anchoring tillage tools 6 of the lateral work units 16 and 17 slope sideways. downwards from the level of the tillage tools 6 of the center work unit 18, compare flg 4. Together, this results in a bridge-arch concave structure of the tillage tools 6, which is largely adapted to the dome-shaped contour of a longitudinal hill.
    If, on the other hand, you drive through a longitudinal gutter-shaped soil sinker, the swing frames 12 and 13 located on the side swing slightly upwards, as shown in fi g 533 800 5, so that the farther tillage tools 6 occupy a higher position than the tillage tools located further towards the grooves. In particular, the configuration of soil adaptation shown in Fig. 5 can be assumed, after which the tillage tools 6 of the centrally located work unit 18 are at approximately the same level, from which the tillage tools 6 of the laterally located work units 16 and 17 rise as a slightly raised wing linearly increasing outwards, compare fi g 5, so that an overall slightly convex, upwardly rising side arrangement of the tillage tools 6 over the entire working width is obtained, which device is substantially adapted to the gutter-shaped longitudinal wave.
    When crossing even ground, on the other hand, the neutral position shown in fi g 3 is obtained, in which the pivot frames 12 and 13 are located in a position between the two bent ground adaptation positions in fi g 4 and 5 and the soil cultivating tools 6 are arranged substantially at a height level. From this neutral position of the working units 16, 17 and 18 on a level surface, the hydraulic cylinders 20 and 21 of the lifting device 19 are movable on both sides.
    In addition, as Fig. 2 conveys, the soil cultivating tools 6 can be height-movably suspended individually or in groups on each frame part, so that in addition to the previously described turning movements also individual soil adaptation movements are achieved with individual packing wheels or individual pulleys, so that overall a very sensitive ground adaptation is achieved.
    The aforementioned downward pivotability in the extended position, shown in fig 4, can preferably be limited by suitable abutments, for example by the maximum extension length of the hydraulic cylinders 20 and 21, to prevent a collision between the tillage tools attached to the pivot frames 12 and 13. 6 and the tools coupled to the frame part 11 located in the middle.
