    Description " DEVICE FOR DISTRIBUTING AGRICULTURAL MATERIAL AND AGRICULTURAL VEHICLE "
    STATE OF THE ART
    Devices for distributing and compacting accumulated agricultural material, in particular with a roller driven about an at least substantially horizontal axis, for acting on, for example, fermentation or silage feed are known.
    Such devices such as silage distributors are designed, for example, as attachments for a variable attachment to agricultural machines such as tractors or Trakto¬ren, the device has a standardized three-point arrangement, which is matched to match available on the tractor coupling points. With the three-point arrangement, the device to be mounted is picked up and optionally supplied with a rotary drive via a drive shaft driven by the tractor.
    The distributor roller has on its lateral surface, for example, helically angeord¬nete scoop-like elements, which is distributed during operation by the rotation or Drehbewegungder roller and the driving movement or thrust of the tractor, the feed and moved to the side and to the front.
    OBJECT AND ADVANTAGES OF THE INVENTION
    The object of the present invention is to improve the abovementioned devices, in particular to distribute agricultural material such as silage more effectively evenly or to compact and level with a straight edge course.
    This object is solved by the independent claims.
    The dependent claims thematize advantageous developments of the invention.
    The invention relates to a device for distributing agricultural material, such as grass silage, with a work roll rotatable about an at least substantially horizontal axis for acting on the agricultural material, wherein the device for a working operation on an agricultural vehicle is attachable such that the A work roll is drivable via a drive provided by the vehicle, wherein a connection of the device to the vehicle via a mounted on agricultural vehicle three-point hitch of the device, and wherein on a cantilever arm of the device to the work roll adjacent positionable delimiting element for a distribution limit of moving from the work roll agricultural Material is available.
    The invention particularly relates to a roller distributor for distributing animal feed, which is designed as an attachment or attachment, for example, for a standar¬disierte coupling means feasible attachment to an agricultural motor vehicle wieeinem tractor or tractor.
    In agricultural machines, the standardized coupling means comprise a triangular or three-point link, which is present on the device, which can be mounted on agricultural vehicle, wherein on the agricultural vehicle, a three-point hitch tuned to the three-point hitch is formed.
    For standardized connection interfaces between a front and / or rear of the tractor and the device for distributing the animal feed are realized. Disadvantageous to the three-point linkage is a gear arrangement of the device with a gearbox and a gear housing which is spaced apart from the three-point linkage and in the vicinity of the work roll. is positioned axially between two sections of a two-part work roll. With the
    Gear arrangement is provided in particular an angular gear connection of the tractor associated drive shaft with a shaft for driving the work roll. With the connection of the device to the vehicle via the three-point linkage, if necessary, a raising and lowering of the device controllable by the vehicle and thus also of the work roll is realized.
    The essence of the invention is that the boom is pivotally mounted on three-point bracket in verschie¬dene spatial directions.
    The device according to the invention is thus advantageous for a flexible use in particular special designed as an attachment to a tractor or tractor. The attachment may be attached to the tractor for e.g. B. the feed distribution are temporarily grown or preferably remain permanently.
    Advantageously, the limiting element present on the cantilever arm in particular can be brought into the ideal position and orientation due to the spatially almost arbitrarily orientable cantilever arm in different ways or for the respective type of operation or use. In addition to different working positions and distances to the work roll, the limiting element can advantageously also be moved to a position "out of operation" even when not in use. be moved away, in which the boom together with limiting element a view of the driver of the tractor to the front or around hardly affected or the limiting element when maneuvering the tractor is no risk of collision with surrounding Ein¬richtungen. The cantilever arm or the delimiting element can for this purpose in particular be swung sideways upwards.
    Advantageously, the device can be used both for Futterverteilbetrieb at Freihau¬fen as well as in a silo. When used in the silo this is easily possible with laterally upwardly pivoted boundary elements between seitli¬chen walls of the silo and also when the silage is piled above the wall height of the silo and then the boundary elements are brought in accordance with the invention in lateral arrangement to the work rolls for litter control can.
    For road driving of the agricultural vehicle, in particular, it is possible to keep a running width small by bringing the restricting member across the width of the work roll and along the axial extent of the work roll, respectively, so that the maximum width in that portion of the apparatus is determined by the width of the distribution roller. As a result, the vehicle width does not exceed a maximum permissible vehicle width determined by the road traffic permit. Thus, the width is transverse to Fahrtrich¬tung the tractor in the field of the device or the work roll against z. For example, it is advantageous for compact positioning of the limiting elements if the length of the limiting elements does not exceed the width of the working roll. In addition, the limiting elements preferably have a height dimension which corresponds to a height or a maximum diameter dimension of the work roll, that is to say with the projections protruding on the lateral surface. B. scoop-like elements, is tuned or this at least approximately corresponds.
    In the described driving mode, it is also advantageous, in terms of safety, that the limiting element suspended in front of the work roll strips off or covers the above optionally sharp-edged blade-like elements on the work roll.
    The attachment point of the cantilever arm directly to the three-point link is opposite to other attachment points on the device such. As an attachment to the gearbox for verschie¬denen reasons advantageous. Since the three-point bracket is further spaced from the work roll and is offset towards the tractor in operation and in the operation according to the invention based on the three-point bracket Auslegerarm compared to an attachment to the transmission housing advantageously to significantly kleiner¬ren contamination or deposits of animal feed on the cantilever arm.
    Preferably, the cantilever arm on an easily accessible oblique leg or
    Carrier of the three-point hitch fixed possibly releasably attached. In particular, for this attachment means of the device for a fixed connection or assembly and disassembly of the then releasably fixable cantilever arm on a leg of two upwardly converging Schenkel of the three-point hitch are available. The detachable variant is advantageous in terms of repair and repair work. In particular, the extension arm is pivotally mounted on the three-point support alone, so it requires no additional attachment point. Accordingly, the attachment means are provided at an end region of the extension arm which is opposite to the free end region with the limiting element held thereon or suspended.
    Further, it is advantageous that exactly two cantilever arms are each provided with a Begrenzungs¬element. This is the standard case. Thus, throwing away distributed material when the work roll is rotating into an undesired, further outward area can be avoided. In particular, on both axial faces of the work roll, the fluidized outwardly spun material may bounce against the respective containment element so that the material alone is evenly distributed on a desired dispensing width of the feed spreader. This is necessary for compaction with the working roller traveling over the feed material or with the tires of the tractor.
    For only in this way can a defined straight edge of a longitudinal side of a drivable raised path formed by the compressed material be formed as desired in a stable manner.
    With the thus formed double-sided equipment of the litter boundary with the two limiting elements, both sides of the work rolls can be controlled, used or disabled, in particular independently of each other.
    Preferably, a left arm are attached to a left oblique leg of the three-point trestle and a right arm on a right oblique leg of the Dreipunkt¬bocks. The three-point link serves as a mounting bracket for the boom arms.
    In particular, the two cantilever arms are identically constructed with the restricting elements. Advantageously, the entire components associated with the boom are constructed with neutral sides, whereby, for example, the attachment means, the arm extension and the Begrenzungsele¬mente or other parts present on the boom arm mirror image left or right wahl¬weise grown on the three-point link and can be used.
    All the above and following made explanations and variants of an extension arm of the device according to the invention also apply mutatis mutandis to two or more cantilever arms of a device according to the invention with a plurality of cantilever arms.
    According to an advantageous variant acting on the cantilever adjustment means are designed such that a continuous adjustment of the extension arm in a variety unterschiedli¬cher positions is possible. The many different positions are relative to the verblei¬benden parts of the device to understand, in particular relative to the work roll as bei¬spielsweise positions in which essential sections of the boom laterally, above or before the work roll or the limiting element in their vicinity Advantageously, the adjusting means comprise articulated and / or pivoting means.
    Alternatively or additionally, the adjusting means may be designed such that the Ver¬stellung of the cantilever arm not continuously but z. B. according to a predetermined grid can result. The adjustment can be motor assisted and / or manually z. B. take place with a suitable tool.
    The adjusting means can in particular work electromotively or hydraulically or are motor or hydraulically actuated. The adjustment can be made in particular via hydraulic piston-cylinder arrangements.
    It is also advantageous that the adjusting means between attachment means, which are provided for receiving the boom arm on the three-point bracket, and a main part of the Ausle¬gerarms are formed. Thus, advantageously, an arrangement for the adjustment movement of the extension arm can be provided close to the three-point block. Such a system allows for many different adjustments and is nevertheless relatively compact and simple in construction.
    A control of the various functions of the adjusting means, for example, for lifting, lowering or pivoting of the boom and the limiting element is realized by appropriate person and a driver of the tractor by appropriate valves and control elements, in particular electro-hydraulically, in particular via a one-handed operation in the vehicle.
    Further, it is advantageous that the adjusting means have a flange. This is in particular particularly stable and compact setup erectable. The flange arrangement advantageously has a first and a second flange element, wherein the first flange element is pivotable about a position-fixed vertical axis and wherein on the first flange element the second flange element is movably received about a horizontal axis. On the second flange element, in turn, a main part of the cantilever arm is firmly attached.
    An advantageous modification of the subject invention is characterized in that the adjusting means comprise two mutually angled axes, each axis is designed for a pivoting movement of the cantilever arm. For example, the two flange members each have a solid axis for their pivotal movement. In particular, there may be exactly two piston-cylinder units, each of which allows movement of the cantilever arm about an associated pivot axis, the two pivot axes being angularly aligned with each other.
    As a rule, a hydraulic supply of the piston-cylinder unit is provided via the agricultural vehicle or the tractor.
    It is also advantageous if the cantilever arm has a curved shape and / or angularly aligned portions. The bent shape or the Mehrfachknickungdes cantilever arm is tuned, for example, to the size and outer shape of the work roll.
    Thus, the cantilever in the work roll, which has a cylindrical gebo¬gene lateral surface are aligned so that the associated Begrenzungsele¬ment can be brought in a variety of different suitable positions, the Ausleger¬arm a sufficient safety distance to the work roll having.
    Preferably, the cantilever arm is adjustable in length. Thus, different axial widths of work rolls can be used with one and the same device.
    It is also advantageous that the limiting element is received via bearing means on Ausle¬gerarm, wherein the bearing means are formed for adjusting the limiting element relative to the boom. The bearing means may comprise, for example, a Gelenkanordnung with a hinge pin and a bearing bush or the like. Thus, the limiting element at the point of attachment to the cantilever arm can be displaced about an axis, e.g. 180 or more degrees pivot.
    Finally, it is also advantageous that the limiting element has recordings, in which stiffening and / or weighting elements are housed. The Beschwe¬rungselemente may for example consist of plastic or steel plates.
    The invention also extends to an agricultural motor vehicle having a device according to one of the above-described embodiments.
    Thus, for example, a tractor or tractor is advantageously equipped for distributing insbeson¬dere of silage feed.

    Transport position from the side, from the top and from the front.
    The figures show a trained as a feed distributor 1 inventive Vorrich¬tung for distributing fermentation fodder or silage in different relative positions of a Wurf¬begrenzung for corresponding operating conditions on an agricultural vehicle bzw.einem tractor 2. The feed distributor 1 is designed as a roller distributor with two support arms 3 and 4 forming the throw limitation, on each of which a baffle cloth 5 or 6 is received.
    The feed distributor 1 accordingly comprises a work roll which can be driven in rotation about an axis of rotation R and which is designed as two distributor rolls 7, 8. The identical distributor rollers 7, 8 rotating about the common rotational axis R are axially separated, with a gear box 9 of the feed distributor 1 being present in a space between the two distributor rollers 7, 8. The gear box 9 is part of an unillustrated bevel gear for transmitting a rotary motion from a shaft 10 of the feed distributor 1 to the two distributor rollers 7, 8. For this purpose, in working mode, the shaft 10 oriented transversely to the axis of rotation R of a driven Treibwel present on the tractor 2 on the front or rear side ¬le 11 rotatably driven via a detachable shaft connection.
    The connection of the feed distributor 1 on the tractor 2 can be made either on a standar¬disierten three-point suspension 13 at the front and at the rear of the tractor 2. For this purpose, the feed distributor 1 has a correspondingly formed on the three-point hitch 13 standardized trained three-point block 12.
    The three-point block 12 comprises in its basic form three mutually triangular Aus¬ directed U-shaped carrier, wherein a lower support 14 is aligned horizontally in operation and at the ends of the two other oblique beams 15 and 16 are zusam¬menlaufend upwards. In the triangular passage framed by the supports 14, 15, 16, the shaft 10 passes through.
    For stopping the feed distributor 1 on a floor surface, for example when not using it and for providing it correctly for coupling to the tractor 2, a vertically adjustable and lockable support foot 19 and 20 is provided on the carrier 14.
    On lateral surfaces of the distributor rollers 7, 8 blade elements 17 are for example welded, which mix by a helical arrangement at a Drehbe¬wegung of the distributor rollers 7, 8 and by the driving movement or thrust of the tractor 2 and thus the feed distributor 1, the silage feed and loosen and sideways wegbewegenern or forward, with the baffles 5, 6 serve as a lateral Wurfbe¬ boundary for this material.
    Above the distributor rollers 7, 8 there is a closed length-adjustable protective frame 18 with upwardly bent loops surrounding the distributor roller outer contour.
    The two support arms 3, 4 are side neutral with respect to the connection to the carriers 15 and 16 or similar and festggf mounting means 21, 22 on the carriers 15 and 16, respectively. releasably screwed on. The attachment means 21, 22 comprise a base flange 23, 24 fixedly attached to the supports 15, 16, on which lower flange 25 pivotable about a vertical axis S1 and upper flange 26 pivotably attached thereto about a horizontal axis S2 are accommodated. At the upper flange 26 is fixedly connected to a rigid main part 27 of the support arms 3 and 4 with each other at an angle to each other firmly positioned in each case substantially straight arm portions 27a, 27b and 27c present. In the illustrated in Figures 3 and 4 working position of the support arms 3 and 4, the arm portion 27a is rising flat, the middle arm portion 27b horizontally and the arm portion 27c steeply aligned down. At the free end of the multi-angled end portion of the arm portion 27c, the blanket 5 and 6 is pivotally received about an axis S3.
    With the console provided by the three-point support 12, a pivoting and tilting device for the support arms 3, 4 can be realized, wherein the baffles 5, 6 within a large spatial area laterally to the distributor rollers 7, 8 different or individually me¬chanisch or hydraulically.
    For hydraulically driven pivotal movement of the support arms 3, 4, the lower flange 24 is pivotable about the pivot axis S1 with a hydraulic cylinder assembly 28 and the upper flange 26 about the axis S2 with a further hydraulic cylinder assembly 29, with an extension and retraction of a corresponding linearly displaceable piston rod the hydraulic cylinder assemblies 28, 29 takes place. The pivot axes S1 and S2 are each realized with a journal engaging through corresponding flange bores. Thus, each support arm 3 or 4 can be positioned almost arbitrarily spatially aligned relative to the remaining areas of the feed distributor 1 and to the distributor rollers 7 and 8, respectively. In addition, a corresponding spatial or angular orientation of the baffles 5, 6 is infinitely or after a grid possible on the pivoting movement of the baffles 5, 6 about the pivot axis S3. The angled adjustment possibilities of the baffles 5, 6 is illustratively compared to the positions of the baffles 5, 6 according to FIG. 1, with the baffles 5, 6 aligned parallel to the end faces of the work rolls 7, 8 and with baffles arranged obliquely 5, 6, whose front vertical edge is placed in the direction of the distribution rollers 7, 8.
    When working feed distributor 1 with the moving tractor 2 in rotating distributer rollers 7 and 8 serve the baffles 5, 6 according to the positions shown in Figures 1 and 2 as a litter boundary for aufgewirbeltes or laterally thrown away feed material.
    The baffles 5, 6 are preferably formed of strong plastic film, which mitschematisch indicated pockets 30 (see Figure 2) are equipped, are sewn in which Verstärk¬kungselemente of plastic or steel plates.
    On the particular continuously adjustable spatial orientation of the support arms 3, 4bzw. the baffles 5, 6, the baffles 5, 6 are positioned in the distributor operation so that a suitable Anstellwin¬kel the baffles 5, 6 is adjustable in each case to the existing throwing direction of the feed material. The desired angular positioning can be set up manually in steps, for example by means of a perforated disc and locking pins, or alternatively by a hydraulic angle adjustment.
    Advantageously, the support arms 3, 4 are formed bent over the main part 27 so that sufficient for the work of the distributor rollers 7, 8 space or space can be established. In addition, the distribution rollers 7, 8 have different widths, so that here too the support arms 3, 4 on the pivoting and the angular adjustment of the baffles 5, 6 can be correspondingly optimally spatially positioned.
    Figures 1 and 2 show a working position with axially lateral arrangement of the baffles 5.6 to the distributor rollers 7, 8, wherein the planar alignment of the baffles 5, 6 are aligned frontally parallel to the distributor rollers 7, 8. FIG. 3 shows a forward or rearward transport position with baffles 5, 6 inclined at an angle to the end faces of the distribution rollers 7, 8. The transport position itself is shown in FIGS. 8 to 10.
    Figures 5 to 7 show the baffles 5, 6 in a position in which they are out of operation, advantageously a view of a driver in the tractor 2 forward and laterally is not limited.
    FIGS. 8, 9 and 10 advantageously show a spatial orientation of the support arms 3, 4 together with the baffles 5, 6 for a road driving operation of the tractor 2 when the distribution rollers 7, 8 are not operating. In this case, the baffles 5, 6 front-parallel to the rotation axis R are aligned to save space. Again, a free view of a driver of the tractor 2 is guaranteed. In addition, a working width of the tractor 2 with the feed distributor 1 is advantageously minimally or according to the width B of the distribution rollers 7, 8 set (see Figure 10), so that the use of public Fahr¬wegen and roads is possible without exceeding the maximum width.
    Advantageously, the arm arms or the support arms 3, 4 are secured in the Fahrstel¬lung for trips on roads and roads and in the yard, for example by being lockable against unintentional lateral swiveling away.
    Due to the enormous maximum lifting height of the litter boundary with the baffles 5, 6 e.g. up to the height of a tractor roof 31 and by the universal positioning of these towels 5, 6 is always guaranteed free visibility for a driver and operator. Especially in free piles the view in free form is of enormous importance for the safety of the Fehmbe drive.
    Advantageously, the baffles 5, 6 may be provided with a luminous color for better Erknnung for the driver of the tractor 2.
    Compared to rotary distributors, roller distributors, such as feed distributor 1, can process higher feed piles or distribute material more metered laterally and forward. Unhindered visibility for a driver of the tractor 2 is achieved by the filigree Aus¬ design of the structure with the support arms 3 and 4, with this oblique and rounded contours an unwanted food storage on the support arms 3, 4und the baffles 5, 6 constructive in operation conditionally takes place to a lesser extent.
    In addition, with the baffles 5, 6 and wind influences can be counteracted with Wegwehenvon feed material. In addition, due to the striking color design of the baffle cloths 5, 6, they can be located at any time in the vortex or dust of the flying feed and a collision with objects or other vehicles can be prevented.
    In addition, due to the universal adjustment possibilities of the support arms 3, 4 in combination with the angular adjustment of the baffles 5 and 6, the adjustments of the throw limit to different tractor sizes and roll widths as well as areas of the feed pile to be processed can be advantageously made.
    Compared to conventional arrangements can be used for various sizes of Vertei¬lerwalzen advantage by the universal Verstellmög¬ the support arms 3, 4 of the feed distributor 1.
    Also contributes to this a length adjustment 32 of the support arms 3, 4 with prepared Lö¬chern and this sweeping plug or screw elements, which here eacheineinem inserted in the hollow arm portion 27b straight portion of the arm portion 27c is realized, which according to the double arrow P1 can be fixed and retractable on the arm portion 27b.
    The widely extending support arms 3, 4 and the universal pivoting possibilities even allow a folding of the baffles 5, 6 for a space-saving storage wäh'rend road trips.
