    CATERPILLAR SUPPORT FOR A BEARER FOR HARVESTING
    CHOPPING FRUITS
    This invention relates to a caterpillar chassis for a harvester for harvesting chopped fruits, comprising a frame and two caterpillar bodies for supporting the frame and for displacing the caterpillar chassis according to a direction of travel, wherein at least one caterpillar body is arranged so as to be movable in height relative to the frame. wherein the caterpillar undercarriage comprises a coupling element which is attached at its first end to a said caterpillar body and is pivotally attached to the frame at its second end, said ends of said coupling element being arranged at a distance from one another in the direction of travel and wherein the caterpillar chassis comprises a support element which, viewed in the direction of travel, is disposed at a distance from the coupling element, is hingedly mounted at its first end to a said caterpillar body, and is hingedly attached to the frame at its second end, said ends according to a direction across d The driving direction and the height direction are arranged at a distance from each other.
    When harvesting root vegetables with the help of a harvester with a caterpillar undercarriage, it is desired to keep the frame flat at all times, irrespective of the unevenness in the ground on which the harvester rides.
    In order to compensate for slopes in the direction of travel, the caterpillar bodies are usually provided with tilting positions relative to the frame.
    Several solutions have already been devised to compensate for slopes across the direction of travel. Usually, at least one of the caterpillar bodies is adjustable in height with respect to the frame. Usually both caterpillar bodies are individually height adjustable with respect to the frame to provide adjustability. Solutions for this are described, for example, in BE 575 071 A1 and US 6,209,669 B1.
    A problem with this is that with changing slopes, a driver must always adjust the height settings of the caterpillar bodies in order to keep the frame flat. An additional problem is that on a slope a harvester also undergoes a course deviation, which means that the driver always has to correct his course.
    With the harvester from EP 1 290 933 BI, a partial solution has already been worked out for this. When adjusting the height of a caterpillar body relative to the frame, a displacement of this caterpillar body in the driving direction of the machine is realized here as a result of the guidance through the parallel connecting rods arranged in the direction of travel. As a result, the support element which is hingedly arranged between a caterpillar body and the frame also carries out a corresponding displacement, so that the caterpillar bodies undergo a slight rotation towards the slope side. This rotation serves to compensate for the price deviation of the harvester.
    In practice, this rotation is not sufficient for all possible surfaces with different friction between the tracks and the surface. In the event of a deviating friction due to a different type of surface or a deviating slope, where the course deviation is not adequately or too much compensated, the frame will be tilted and the cut fruits will roll in the same direction.
    The object of this invention is to provide a caterpillar undercarriage for a harvester with which the frame can be adjusted as flat as possible at all times, independently of the condition of the substrate and this with compensation for course deviations.
    This object of the invention is achieved by providing a caterpillar chassis for a harvester for harvesting fruit, comprising a frame and two caterpillar bodies for supporting the frame and for moving the caterpillar chassis in a direction of travel, wherein at least one caterpillar height is arranged so as to be movable relative to the frame, wherein the caterpillar chassis comprises a coupling element, which is attached at its first end to a said caterpillar body and is pivotally mounted at its second end to the frame, said ends of this coupling element viewed in the direction of travel, are arranged at a distance from each other and wherein the coupling element is made adjustable in length between its said ends, and wherein the caterpillar chassis comprises a support element which, viewed in the direction of travel, is arranged at a distance from the coupling element, is hingedly mounted at its first end to a named ru body, and at its second end is hingedly attached to the frame, said ends being arranged at a distance from each other, viewed in a direction transverse to the direction of travel and the height direction.
    According to the invention, the coupling element between the caterpillar undercarriage and the frame is no longer a fixed element, but its length is adjustable between said ends. By adjusting the height of a caterpillar body on the one hand and adjusting the length of this coupling element on the other, it becomes possible to keep the frame flat at all times by means of the height adjustment with compensation for course deviations by adjusting the length of the coupling element. You can continue to grub in any situation, while the harvester can be adjusted with the aid of the height adjustment and the length adjustment in order to get rid of every problem situation.
    The height setting can be done manually. Typically, however, they will rather be set automatically based on real-time measurements. To this end, this height adjustment is typically checked with the aid of an electronic spirit level (gravitational sensor) that controls the inclination of the harvester in a direction transverse to the direction of travel. The measurements of such an electronic spirit level are transmitted to a processing unit / control unit for processing thereof and for controlling the height adjustment of the caterpillar body. The slope of the frame is hereby continuously adjusted, so that the harvester always remains flat in a direction transverse to the direction of travel, at least as far as the mechanical range of the system permits.
    The length setting can also be done manually. Preferably, however, both the height adjustment and this length adjustment are performed automatically and continuously adjusted on the basis of real-time measurements. If the harvester must follow a trail of the chopped fruit, for example, a track finder can be used for this purpose. When this locator then comes, for example, to the end of the range, the length setting of the coupling element can be adjusted. When the height adjustment and / or the length adjustment is realized automatically, the option is preferably also left open to be able to intervene and to be able to adjust these settings actively / manually.
    The caterpillar body to which the coupling element is attached preferably comprises wheels, a caterpillar frame on which the wheels are rotatably suspended and a supporting body which is arranged tiltably with respect to the caterpillar frame, the coupling element being at its first end on the supporting body of the corresponding caterpillar body attached to attach this coupling element - as previously described - to this caterpillar body.
    Such a tiltable suspension is known to provide the rest of the caterpillar body tiltably with respect to the frame with the aid of such a tiltable carrying body, so that slopes in the direction of travel are compensated and the frame remains practically flat in this direction.
    A caterpillar undercarriage according to this invention with a caterpillar body having such a support body, preferably comprises a height-adjustable support element, which is attached at its first end to the support body and is attached at its second end to the frame about the corresponding caterpillar body movable in height. relative to the frame.
    If desired, for example if certain parts of the frame or the caterpillar body could be damaged by tilting the support body, a caterpillar undercarriage according to this invention with a caterpillar body with such a support body preferably comprises a limiting element for limiting the tilting movement of the supporting body. supporting body relative to the caterpillar frame.
    In order to prevent kinking of the carrying body in the case of (sudden) movements of the caterpillar undercarriage in the direction of travel, the coupling element of a caterpillar undercarriage according to the present invention is furthermore preferably attached at its first end to the supporting body with only one degree of freedom, this degree of freedom being a rotation movement. allows substantially along a horizontal plane between the coupling element and the supporting body. This is also necessary to keep the support body stable around the tiltable arrangement of the rest of the caterpillar body.
    More specifically, this can be achieved, for example, by attaching the coupling element at its first end to the support body at two points at a mutual distance.
    In a preferred specific embodiment the coupling element is attached to the corresponding caterpillar body by means of one or more ball joints (ball couplings). With the aid of such ball joints, the coupling element can be given the desired freedom of movement.
    The coupling element of a caterpillar undercarriage according to the present invention preferably comprises a hydraulic cylinder for designing it to be adjustable in length between its said ends.
    In such a caterpillar undercarriage with hydraulic cylinder, wherein this caterpillar undercarriage also comprises a support body, to which the coupling element at its first end is attached at two points at a mutual distance, the coupling element in a specific embodiment preferably comprises a guide element, which is the first end of the coupling element, and the coupling element comprises a guide rod, which comprises the second end of the coupling element, wherein the guide rod is arranged conductively in the guide element via their ends opposite to the first and the second end of the coupling element and wherein the guide rod is of the hydraulic cylinder is movably connected to the guide element.
    A further specific embodiment of a crawler chassis according to the present invention comprises a second coupling element which is arranged parallel to the first-mentioned coupling element and which is attached at its first end to the corresponding caterpillar body and is pivotally attached to the frame at its second end.
    Even more specifically, this second coupling element can also be made adjustable in length. However, this is not a necessity.
    When a caterpillar undercarriage according to the present invention is provided with both a length-adjustable first-mentioned coupling element and a length-adjustable second coupling element, both the first-mentioned coupling element and the second coupling element preferably comprise a hydraulic cylinder for this purpose.
    The caterpillar bodies of a caterpillar undercarriage according to the present invention are furthermore preferably mutually coupled with the aid of a fixed coupling rod. The support element can then be more specifically attached to this coupling rod at its first end to attach it to a said caterpillar body.
    Even more specifically, the caterpillar undercarriage can then comprise a height-adjustable support element, which is attached at its first end to the coupling rod and is attached to the frame at its second end.
    With such a support element that is arranged at least partially between the caterpillar bodies, forces that have to be transferred from the frame to the caterpillar bodies can be transferred better.
    Such a caterpillar undercarriage preferably comprises both height-adjustable support elements arranged on the outer sides of the caterpillar bodies, and one or more height-adjustable support elements arranged between the caterpillar bodies.
    A particularly preferred embodiment of a caterpillar undercarriage according to the present invention comprises a coupling element mentioned per caterpillar body.
    Furthermore, each caterpillar body is preferably positioned in height-adjustable manner relative to the frame.
    The object of this invention is furthermore also achieved by providing a harvester, more specifically potato harvester, with a caterpillar undercarriage according to the present invention.

    The caterpillar undercarriage (1) shown is provided to form part of a potato harvester. For this purpose, a pick-up device is then provided at the front of this caterpillar undercarriage (1) (left in Figure 1), conveyor belts are provided subsequent to this pick-up device, which conveyors end up in a collecting bin centrally on the caterpillar undercarriage (1), above the caterpillar bodies (3, 4) a cabin for the driver and comes at the rear of the frame (2) a machine housing. The construction of the remaining parts of a potato harvester in relation to such a caterpillar undercarriage (1) is known and does not form part of the invention, so that it is not necessary to go into this in greater depth.
    The caterpillar underbody (1) itself comprises a frame (2) below which a caterpillar body (3, 4) is arranged on either side of the frame (2). A steering wheel (14) is arranged under the rear of the frame (2).
    Each caterpillar body (3, 4) comprises a plurality of wheels (7), which are rotatably suspended from a caterpillar stream (8). A caterpillar track (22) is arranged around the wheels (7). Furthermore, each caterpillar body (3, 4) comprises a support body (9) which is tiltably attached to the caterpillar frame (8). The construction of such caterpillar bodies (3, 4) is also known, so that this is not discussed in more detail.
    Both caterpillar bodies (3, 4) are interconnected by means of a fixed coupling rod (13), as can be seen in figures 3, 11 and 15. Through this fixed coupling rod (13) and the supporting bodies (9) there is an axis for this purpose applied. To this end, this fixed coupling rod (13) is further bolted on one side to the corresponding support body (9) and is hinged on one side with respect to the corresponding support body (9). The fixed coupling rod (13) is also rotatable in this way with respect to each of the caterpillar bodies (3, 4).
    On the side where the coupling rod (13) is bolted to the corresponding support body (9), a limiting element (11) is provided for limiting the tilting movement of the support body (9) relative to the caterpillar effect (8).
    Each caterpillar body (3, 4) is connected to the frame (2) in three different ways.
    A first connection between each caterpillar body (3, 4) and the frame (2) is realized with the aid of four hydraulic cylinders (10, 23), which allow an adjustment according to the height direction (H). A first hydraulic cylinder (10) is provided per caterpillar body (3, 4) and is hingedly connected at a first end to the bearing body (9) of the corresponding caterpillar body (3, 4) and is hingedly connected to the ffame at a second end ( 2). Two second hydraulic cylinders (23) are arranged between the caterpillar bodies and are pivotally connected at a first end to the coupling rod (13) and pivotally connected at a second end to a crossbar (15) of the frame (2). With the aid of these four hydraulic cylinders (10, 23), by varying the height of the different hydraulic cylinders (10, 23), the frame (2) can be tilted to the left as desired (see figures 11-13) or be tilted to the right (see Figures 14-16).
    A second connection between each caterpillar body (3, 4) and the frame (2) is realized by means of a coupling element (5) per caterpillar body (3, 4) which is attached at its first end to the supporting body (9) of the corresponding one caterpillar body (3, 4) and hinged at its second end to the frame (2). The ends of each coupling element (5) are arranged at a distance from each other, viewed in the direction of travel (A).
    Each coupling element (5) comprises - as can be seen in Figure 17 - a guide element (21) which comprises the first end of the coupling element (5) and which is attached to the corresponding bearing body (9) by means of two ball joints (12) . Because these attachment points (12) are realized with ball joints (12), freedom of movement of the coupling element (5) remains in a horizontal plane.
    Furthermore, each coupling element (5) comprises a guide rod (19) which comprises the second end of the coupling element (5). With its other end, this guide rod (19) is arranged conductively via the end of the guide element (21) opposite the first end of the coupling element (5) in the guide element (21) and is attached to this with the aid of a hydraulic cylinder (20). guide element (21) attached. By adjusting the length of the hydraulic cylinders (20) of the coupling elements (5) differently, the caterpillar bodies (3, 4) can be adjusted to the left (see figures 5-7) or adjusted to the right (see figures 9-12) .
    In order to keep the caterpillar bodies (3, 4) stable in a direction transverse to the direction of travel (A) with respect to the frame (2), the frame (2) - viewed in the direction of travel (A) - is at a distance from the coupling elements (5) connected with the aid of a support element (6), which at a first end is hingedly attached with the aid of a coupling element (17) to the coupling rod (13) between the caterpillar bodies (3, 4) and to its other end with is pivotally attached to said crossbar (15) of the frame (2) by means of a coupling element (16). The ends of this support element (6), viewed in a direction transverse to the direction of travel (A) and the height direction (H), are arranged at a distance from each other.
