    Agricultural implement
    The present invention relates to an agricultural implement with a height-adjustable device, preferably in the form of a pick-up with a spine roller, which can be supported on the ground by at least one feeler wheel, the feeler wheel pivotable between a The operating position increasing the width of the device and a transport position reducing the width of the device is suspended, the feeler wheel suspension comprising a pivot arm which on the one hand carries the feeler wheel and on the other hand on a suspension carrier about a pivot axis which extends substantially perpendicular to a lying, transversely extending transversely to the direction of travel, is pivotally suspended between said working and transporting position, said suspension support being pivotally mounted about a substantially parallel tilting axis relative to the transverse axis lying.
    In order to increase the working and surface yield of the agricultural implement, devices provided therewith are designed to be as wide as possible, in order to be able to process the widest possible soil, in particular crop strip, when driving a working track. For example, with loading wagons and / or baling presses and / or mobile forage harvesters, the pick-up device, which can be designed in the form of a pick-up with a rotating spine roller, for example, is designed to be as wide as possible in order to be able to take up broad crop swaths. On the other hand, the said establishments may not be wider than the traffic law permits.
    Part of this problem is the touch-driving devices usually provided on such pick-up devices, in particular support wheels, which scan the soil and will carry the device over the soil and its depressions and elevations at a desired height on undulating terrain. For this purpose, the feeler wheels should, in the working position, drive forward at least at the height of the receiving area of the device or a piece further, in order to prevent the device from, for example, running on an elevation in the ground before the feeler wheel could have lifted the device. On the other hand, the feeler wheel does not, of course, have to travel in front of the device itself, in order to prevent the crop from being compressed and, in particular in the case of a crop, to push the crop away. The feeler wheels are therefore positioned at least laterally adjacent to the device in the working position, approximately at the level of the receiving area of the device or somewhat ahead of it. However, in this case the width, in particular the extension in the transverse direction, increases. The projection of the feeler wheels laterally contributes to the actual working width of the device, that is to say that the total width consists of the effective working width and the lateral position of the feeler wheels.
    To remedy this, i.e. to remedy the lateral projection of the feeler wheels, i.e. to reduce it, and to be able to increase the effective working width substantially to the available street transport width, fold-away feeler wheel devices are provided, the feeler wheels from the aforementioned working position being provided in a transport position reducing the effective width of the device can be brought. Such a pivotable feeler wheel suspension is disclosed, for example, in EP 1 048 195 B1. Herein it is shown to provide two support arms laterally next to the pick-up of a harvesting machine, which for height adjustment of the feeler wheels are connected about a horizontal transverse axis to the side parts of the pick-up itself and each bear a parallelogram guide at a front end for pivotably guiding a feel wheel. Said parallelogram guide comprises two hinge arms which are hingedly connected to the said lateral bearing arm via upright axes and, on the other hand, bear the hinge axis of the wheel fork. By means of the hinges of said parallelogram mechanism, the feeler wheel can be brought from a laterally projecting working position into a transport position for the pick-up, wherein the feeler wheel is pivotable between the two pivot bars of the parallelogram guide such that the feeler wheel is in any intermediate position remains usable, i.e. can support the pick-up, and in particular also remains active in the transport position in front of the pick-up.
    However, this parallelogram hinge suspension of the feeler wheel is disadvantageous for several reasons. In addition to an increased number of parts and the associated increased blocking sensitivity, for example due to refusing hinges, in particular the limited storage capacity of the feeler wheel in the transport position is disadvantageous. The transport position for the pick-up increases the length of the pick-up in the transport position to the front, which requires an increased drawbar length to avoid collision with the leading tractor when turning a tight bend. In addition, the accessibility to the inside of the transport channel of the device is reduced, for example in order to be able to remove contamination or blockages in the transport channel in advance. The double hinge arms also have the hinge achieved relative to the maximum possible hinge angle, since with a change of a hinge angle through approximately 180 ° the arms will move over each other, which is only due to complicated positioning of the arms in different planes or excessive bending arm contours can be made possible.
    The object of the present invention is to provide an improved agricultural implement of the types mentioned in the preamble, which reduces disadvantages of the prior art and the latter are further developed in an advantageous manner. In particular, with a simple, stable structure of the feeler wheel suspension, a space-saving storage ability of the feeler wheel in the transport position and a stable guidance of the feeler wheel in the working position will be achieved.
    According to the invention this object is achieved with an agricultural implement according to claim 1. Preferred embodiments according to the invention are part of the dependent claims.
    To this end, it is proposed that the feeler wheel be hinged spatially about several axes between transport and operating position, so that even in limited, difficult-to-access spaces, the feeler wheel can pivot as much as possible in an area for transport lying within the working track width of the device, not to collide with the device and not having to provide size-promoting suspension devices. According to the invention, a hinge control device of the agricultural implement provides a two-axis spatial hinging of the feeler wheel between a working and a transport position such that the hinge arm carrying the feeler wheel, together with the hinge axis of the hinge arm, by tilting the suspension carrier about a transversely extending tilt axis with respect to the device and is further pivoted about said pivot axis with respect to the suspension support and with respect to the device. By multi-axis pivoting of the pivot arm carrying the feeler wheel when moving from the working position to the transport position and vice versa from the transport position to the working position, collisions with the contour of the device and the machine frame can be better prevented.
    In particular, the feeler wheel in an advantageous further embodiment according to the invention can be brought by the multi-axis pivotability of said hinge arm relative to the device into a transport position which, viewed in the direction of movement, lies behind the device, wherein the feeler wheel advantageously so far to the rear It can be swung that it is completely within the track defined by the effective working width of the device. If a pick-up device for receiving harvested goods is provided as a device, for example in the form of a pick-up with pickle roller or another pick-up rotor, in an advantageous further embodiment according to the invention the feeler wheel can be in a transport position behind the pick-up device below the rear of the device. connecting chassis part, in particular a transport channel bottom. As a result, the space available under the machine part connecting backwards to the sensor is utilized. At the same time, accessibility to the pick-up is guaranteed from the front in the transport position. In the working position, however, the feeler wheel can be provided sideways next to the pick-up, approximately - viewed in the direction of travel - at the height of its pick-up, in particular operating range.
    In order to obtain a sufficiently wide movement during spatial pivoting relative to the device and thereby obtain favorable lever ratios, in a further advantageous embodiment according to the invention, the aforementioned horizontal tilting axis of the suspension support of the device can be remotely, preferably in the direction of travel. are provided behind the device, wherein the suspension carrier is advantageously suspended not from the device itself but from a frame part of the machine, against which the device can be adjusted in height in the said manner. Alternatively, it is also possible to arrange the said tilt axis on the device itself. However, the aforementioned placement of the tilting axis at a distance, in particular diagonally behind and below the device, is preferred in order to obtain favorable lever ratios when the sensor wheel is moved into the transport position behind / under the device. Since the aforesaid pivotal arm, which bears the feeler wheel, advantageously extends forward from the pivotable suspension on the suspension carrier in the direction of travel, advantageously in horizontal, only slightly angled, direction with respect to the horizontal. the arrangement of said tilting axis behind and obliquely below the device the hinge surface for the hinge arm is brought into the desired direction by tilting the hinge axis in order to be able to bring the feeler wheel under the chassis part connecting backwards to the device.
    The device itself can be made adjustable in height in various ways.
    For example, it is conceivable for the device to be linearly height-adjustable, for example in the vertical direction or obliquely relative to it, of a movable design. In a further embodiment according to the invention, the device can in particular also be hinged, in particular tiltable, about a horizontal transverse axis, such that a height adjustment is achieved by hinging the device about said horizontal transverse axis. For example, the device can be designed in a manner known per se as a pick-up, the side parts of which extend obliquely forward and down and are pivotally suspended at their rear upper end, so that the pick-up can move up and down by hinging said side parts. . Optionally, a multi-conductive, in particular multi-part or multi-hinged suspension can also be provided.
    If the device is pivotably suspended, in particular tiltable, about said horizontal transverse axis, it can be provided in an advantageous manner that the horizontal tilting axis of the feeler wheel suspension extending transversely to the direction of travel is provided at a distance from said horizontal transverse axis about which the device is hinged in height. In an advantageous further embodiment according to the invention, the tilting axis can be provided with the feeler wheel suspension under the transverse axis of the device. In particular approximately in an area which, relative to the direction of travel, is approximately at the level of the transverse hinge axis of the device or somewhat behind it. The height of the pivot axis of the feeler wheel suspension can be approximately halfway between the height of the cross-hinge axis of the device and the ground. Depending on the configuration of the device and the available space, however, other positions of the tilt axis of the feeler wheel suspension can also be advantageous.
    The control of the spatial transmission of the feeler wheel and the coordination of the pivotal movement about the plurality of pivot axes can, in principle, be carried out in various ways, in particular. For example, in a further embodiment of the invention, each pivot and tilt axis of the feeler wheel suspension may be provided with an actuator driven by external energy, for example in the form of a high-pressure cylinder, wherein the control of the relevant pivotal movement is controlled by a control device, relevant adjusting actuators are controlled, wherein optionally a ramp-in, in particular follow-on control can be realized, in order to be able to control the order of the pivotal movement or the tilting movement on each other in the desired manner.
    Alternatively or additionally, however, at least one of the pivotal or tilting movements can also be coupled to the height-adjusting movement of the device, advantageously by a coupling mechanism designed for this purpose between the feeler wheel suspension and the device, in particular its height-adjusting means. In particular, in an advantageous further embodiment according to the invention, the above-mentioned hinge steering device can be provided with a coupling between the suspension carrier of the feeler wheel suspension and the device, said coupling being advantageously designed such that when lifting / lowering the device a tilting of the articulated arm of the feeler wheel suspension and its articulated axis relative to the device. The pivot arm and its pivot axis are advantageously both tilted automatically when the device is lifted or lowered, and advantageously such that the pivot axis of the pivot arm is brought into its transport position when the device is lifted, and vice versa when the device is lowered into its operating position. working position is tilted.
    The orientation of said pivot axis about which the pivot arm is pivotable relative to the suspension support can depend on the configuration of the device and / or the space available in its environment. In an advantageous further embodiment according to the invention, it can be advantageous here, in particular if the device is a pick-up device, for example in the form of a pick-up device, that the said hinge control device is designed such that the hinge axis of the hinge arm is in its transport position and / or or in the raised position of the device extends approximately vertically, and in its working position and / or in the lowered position of the device is tilted over an acute angle with respect to the vertical, for example through an angle of about 10 ° -50 °, preferably 20 ° - 40 °.
    If a coupling device is provided between the suspension carrier and the device, in particular its height-adjusting means, for tilting said pivot axis, the coupling device can advantageously comprise at least one connecting arm which connects the suspension carrier to a side part of the device, the connecting arm being advantageously is pivotally connected to said side part and comprises a lever arm with respect to the tilt axis on the suspension carrier such that when the device is moved upwards, the suspension carrier is tilted about said tilt axis.
    The pivotability of the pivot arm relative to the aforementioned pivot axis with respect to the device and the suspension carrier can advantageously be controlled independently of the height-adjusting movement of the device. In particular, an adjusting actuator powered by external energy can be provided, which does not compulsively convert the height adjusting movement of the device into a pivoting movement of the pivoting arm. Nevertheless, the control device can advantageously be designed such that the pivotal movement of the pivot arm about the pivot axis following the tilting movement about the pivot axis and / or the height adjustment movement of the device is arranged or adjusted to it, advantageously such that the pivoting of the pivot arm about the pivot axis in the transport position and / or in the working position only when the tilt axis is brought into the transport position and / or the device is specified in the transport position and / or the said pivot movement is only completed when the tilt axis is in its transport position and / or the device is in its raised position. Alternatively or additionally, the pivotal arm can first be pivoted forwards with respect to said pivot axis in its working position, before the device is lowered and / or the tilting axis is tilted into its operating position.
    In order to pivot a pivot arm relative to the device and relative to the suspension support, a setting actuator driven in particular by external energy may be provided, for example in the form of a high-pressure cylinder.
    In an advantageous further embodiment according to the invention, a multiple adjustment lever mechanism can be provided between the suspension carrier and the hinge arm for pivoting the hinge arm relative to the suspension carrier about said hinge axis. By means of such a multi-stage adjustment lever mechanism, even with a small adjustment path of the adjustment actuator, a large articulation path of the articulation lever can be obtained. Alternatively or additionally, a sufficient hinge force can be achieved with limited adjustment forces of the adjustment actuator.
    Said multiple adjustment lever mechanism can herein advantageously comprise at least two adjustment levers, one of which is advantageously hinged to said suspension support and another is hinged to said hinge arm, wherein the two adjustment levers can advantageously be indirectly or directly hingedly connected to each other , in particular such that the two adjusting levers form a two-legged and / or two-legged hinge lever. The suspension points of the suspension carrier on the one hand and the hinge arm on the other hand are both at a distance from the hinge axis, with respect to which the hinge arm can be hinged relative to the suspension carrier, in order to obtain a correspondingly favorable lever. The spacing of the suspension points of the pivot axis can in this case take place in different directions. For an advantageous further embodiment, said at least two adjustment levers can be placed at a distance from the opposite side of the pivot axis.
    In an advantageous further embodiment according to the invention, the adjusting lever mechanism can also comprise a third adjusting lever, which is advantageously suspended pivotally on one of the adjusting levers and is at least slidably connected to the other adjusting lever and / or movable in another way. In particular, said third adjusting lever can be slidably and pivotally suspended on said other adjusting lever in a longitudinal guide.
    Said adjustment actuator can engage at various locations on said adjustment lever mechanism. According to an advantageous embodiment of the invention, it may be provided here that the adjustment actuator engages said third adjustment lever, in particular in the region of its slidable coupling. With its mounting part, the said adjusting actuator can be suspended at various points, for example from a machine frame fixed part. In order to avoid having to provide additional hingeability due to the tilting movement, in an advantageous further embodiment according to the invention, the said adjusting actuator can be hingedly connected with its mounting part to the suspension support.
    In order to stably guide the articulated arm in its working position and / or not to overload the articulated axis or articulated arm in the region of the articulated axis, in a further embodiment of the invention the articulated arm can be provided with a detachable centering and / or securing device for centering and / or securing in the working position, which keeps the hinge arm in its working position in a position at a distance from the hinge axis. Advantageously, said centering and / or securing device can be designed such that the centering and / or securing device can be brought into engagement and out of engagement by pivoting of the pivot arm about the pivot axis, i.e. the centering and / or securing device is released or inversely brought into engagement when the hinge arm is pivoted between transport and operating position.
    In a further embodiment according to the invention, said centering and / or securing device can comprise a centering and / or holding element placed at a distance from the pivot axis, which can advantageously be designed as a conical centering element, which has a positive connection between the hinge arm on the one hand and forms a side part of the device or a bearing part connected to the suspension support, when the hinge arm is pivoted in the working position.
    The feeler wheel can be pivotally connected to the said hinge arm in different ways in the base, for example the feeler wheel can be rigidly mounted on the hinge arm so as to be rotatable about the wheel axis. In an advantageous further embodiment according to the invention, the hinge arm can carry a wheel fork in which the feeler wheel is rotatably suspended about its axis of rotation, wherein the said wheel fork can be of two-armed design, but can also be of one-armed design with a side arm. Advantageously, said wheel fork is pivotally suspended from the hinge arm by means of a fork steering axle, wherein said fork steering axle can advantageously extend approximately perpendicularly to the longitudinal axis of the hinge arm. In an advantageous further embodiment according to the invention, the said wheel fork is pivotally suspended on the said pivot arm only, that is to say that no further steps are provided towards said wheel fork. The steering axle is only hinged to the hinge arm.
    The design of said fork steering shaft can be designed in various ways in the base, advantageously such that said fork steering shaft in the working position of the feeler wheel extends at an acute angle with respect to the vertical, advantageously slightly obliquely downwards and forwards, in the particularly when the wheel axle, viewed in the direction of travel, is provided somewhat behind the said wheel fork steering axle.
    Said hinge arm of the feeler wheel suspension can be designed in different ways in the base, for example have a straight bar-shaped course. In an advantageous further embodiment according to the invention, said hinge arm can have a curved and / or kinked course, in particular such that an arm part extending near the hinge axis in the transport position extends substantially parallel to the direction of travel, while a further the arm part lying at the wheel in the working position with respect to the direction of movement projects outwards at an acute angle. As a result, with sufficient controllability of the feeler wheel in the working position, a support of the pivot arm can be achieved, for example, by abutting against a side part of the device and / or by the aforementioned centering and securing device and / or in the transport position a far inward positioning of the touch wheel can be reached.
    In a further embodiment according to the invention, said suspension support can also have a curved and / or kinked course. Alternatively or additionally, the tiltable suspension of the suspension support may be arranged around the aforementioned horizontal, transversely extending tilt axis relative to the pivot axis, i.e., offset transversely to the direction of travel, said tilting suspension of the suspension carriers indirectly the outer edge of the side contour of the device or, advantageously, light to the inside of the side contour of the device is provided.
    The invention will be explained in more detail below with reference to an exemplary embodiment and associated drawings. In the drawings:

    FIG. 12: a perspective view of the insulated feeler wheel suspension in accordance with FIG. 1 from a viewing angle from above at the rear.
    As shown in FIG. 1, the agricultural implement can be designed as a loading wagon 1, which can be pulled, for example, by a tractor. The agricultural implement can herein comprise a row undercarriage 2, by means of which a chassis 3 is supported on the ground, which can for instance be connected to the tractor by means of a drawbar 4. A pick-up device can be provided as device 5, for example in the form of a liftable and lowerable pick-up 6, which can comprise a pick-up rotor in a manner known per se, for example in the form of a spine roller, in order to be able to pick up harvested material lying on the ground.
    Said device 5 can be supported on the ground by feeler wheels 7, which feeler wheels are advantageously located laterally to the right and left of the device 5 in working position and - seen in the direction of travel - can be provided approximately at the height of the spine roller.
    Such as a comparison with FIG. 3 and 6, the device 5 can be lifted and lowered in a manner known per se, for example by hinges about a horizontal transverse axis 8, which can be located above the working area of the device 5, for example slightly below the chassis 3. In the in particular, side parts 9 of the device 5 can be pivotally suspended about the transverse axis 8. By means of an appropriate hinge actuator, for example in the form of a high-pressure cylinder, the device 5 can thus be lifted and lowered by turning about the transverse axis 8.
    The feeler wheel 7 placed sideways next to the device in the working position is suspended by a feeler wheel suspension 10, with which the feeler wheel 7 is positioned between the 2 in the operating position shown in FIG. 8 can be hinged behind the device 5 and back, as will be explained.
    As shown in FIG. 11 and 12, the feeler wheel suspension 10 comprises a pivot arm 11 which carries the feeler wheel 7 in the region of its projecting end. Here, the feeler wheel 7 can be rotatably suspended on a wheel fork 12 about its wheel axle, wherein in the embodiment shown the wheel fork 12 is of one-armed design. Said wheel fork 12 is suspended rotatably about a fork steering shaft 13 from the pivot arm 11, wherein said fork steering shaft 13 can extend substantially perpendicular to the longitudinal axis of the pivot arm 11. The rotatability of the wheel fork 12 about the fork steering axle 13 can be limited by stops 14 and 15, so as to allow only a limited pivoting of the feeler wheel. The wheel fork 13 is only suspended from the hinge arm 11.
    On the other hand, the pivot arm 11 is pivotally hung with its other end on a suspension support 16, and about a pivot axis 17, which connects the pivot arm 11 indirectly to each other around the suspension support 16 and substantially - generally speaking - perpendicularly to the longitudinal axis of the pivot arm 11 and the suspension carrier 16 extends. In the working position of the feeler wheel 7, the said pivot axis extends in a vertical plane comprising the direction of travel, the said pivot axis 17 being tilted slightly forward with respect to the vertical, see FIG. 3.
    Said suspension carrier 16 extends substantially horizontally transversely of the direction of travel, while said suspension carrier 16 is provided behind the device 5 and / or under the chassis 3. In particular, said suspension support 16 can extend behind the device 5 below the transverse axis 8 and with its part carrying the pivot axis 17, the side contour of the device 5 touches, in particular slightly beyond these, so that the pivot axis 17 is substantially short lies on the side contour of the device 5, see Figs. 4.
    The suspension carrier 16 is hereby not rigidly attached to the chassis 3 or to a part fixedly connected to the chassis, but can be tilted about a tilting axis 18 extending transversely to the direction of travel. Said tilting axis 18 here extends substantially parallel to the transverse axis 8, around which the pick-up 8 can be pivoted upwards, the tilting axis 18 being spaced apart from the transverse axis 8. As shown in FIG. 3, the tilting axis 18 lies - roughly speaking - below and / or somewhat behind said transverse axis 8, advantageously approximately at half height between said transverse axis 8 and the ground. Viewed in the direction of travel, the tilting axis 18 is somewhat behind the pivotal axis 17, but the distance between the tilting axis 18 and the pivotal axis 17 in the direction of travel is less than 50% of the length of the articulated arm 17.
    In order to tilt the suspension carrier 16 about the tilting axis 18, the suspension carrier 16 is coupled to the device 5. The coupling 19 in question comprises connecting arm 20 which is tiltably connected to the suspension carrier 16 with respect to the tilting axle 18 and on the other hand to the device 5, in particular is pivotally suspended on its side parts 9, see Figs. 8 and 9. Said connecting arm 20 can in this case be connected to the suspension carrier 16 in the region of the pivot axis 17, wherein the connecting arm 20 can be pivotable relative to the suspension carrier 16 relative to the suspension carrier 16, advantageously the connecting arm 20 can be hinged are suspended from a guide element 21 which is pivotally connected with respect to the pivot axis 18 and pivotally with respect to the pivot axis 17 to the suspension carrier 16. Optionally, said guide arm can also be rigidly attached to suspension support 16. The guide element can form a plate and / or have a collar-like structure which extends forwards sideways relative to the device 5 substantially parallel to the direction of travel, see FIG. 8.
    The coupling 19 of the suspension support 16 with the device 5 is advantageously designed in such a way that the suspension support 16 and the pivot axis 17 attached thereto tilt when the device 5 is moved upwards in its lifted position into a more inclined position, in particular in a tilted position. approximately vertical position, such as that shown in FIG. 6, while inversely in the lowered working position of the device 5, the tilting axis 18 extends vertically at an acute angle.
    The pivot arm 11 can be pivoted relative to the suspension carrier 16 and the pivot axis 17 by means of a multiple adjustment lever mechanism 22, which is provided between the suspension carrier 16 and pivot arm 11, and an adjustment actuator 23. As shown in FIG. 11 and 12, said adjusting lever mechanism 22 may comprise a first arm 24 pivotally suspended from the pivot axis 17 on the suspension carrier 16, as well as a second arm 25 spaced from the pivot axis 17 on the pivot arm 11. is hinged. The first and second arm 24 and 25 are further hingedly connected to each other, so that they bridge the hinge axis 17 between the suspension carrier 16 and the hinge arm 18 as a two-part mechanism. Furthermore, a third arm 26 is hingedly connected to said second arm 25, which arm, on the other hand, is again slidably suspended in a length slot 27 and pivotally on the first arm 24.
    The adjusting actuator 23, in the form of a high-pressure cylinder, engages on said arm 26, such that said arm 26, such that the adjusting lever mechanism 22 and the adjusting actuator 23 can effect the desired pivotal movement about the pivot axis 17.
    In the hinged forward working position, the hinge arm 11 is thereby locked to the aforementioned connecting arm 20. As shown in FIG. 8, a centering cone 28 can be provided on the hinge arm 11 and / or on the connecting arm 20, which converges the two parts mentioned in the working position with each other in locking engagement. Said centering cone 28 forms a centering and securing device with which the hinge arm 11 can be held in its working position and that at a point spaced from the hinge axis 17, whereby the hinge axis 17 is relieved.
    As a comparison of FIGs. 2 - 10, the feeler wheel 7 can be removed from the 2-4 can be brought into the transport position by lifting the device 5. As a result, the feeler wheel suspension 10 tilts about the tilting axis 18 in the 5 to 7, in which the pivot axis is already in the transport position, and the pivot arm 11, however, is still forward in its position comprising the device 5 sideways.
    In a second step, the hinge arm 11 is then pivoted backwards relative to device 5 and relative to suspension carrier 16, until the feeler wheel 7 is located behind device 5 and under chassis 3. As shown in FIG. 8 and 10, the feeler wheel 7 is completely within the track of the device 5 below the chassis 3.
