    Verstellanordnunq for adjusting the working gap of a basket of a Presch- and / or
    separator
    description
    The invention relates to an adjusting arrangement for adjusting the working gap of a basket of a threshing and / or separating device,
    Technological background
    In the harvest of threshed fruits, which are passed between a threshing or separating drum and a threshing or separating basket associated therewith, in many cases there is the need to adjust the gap between the drum and the basket in order to adapt it to the crop type and / or adjust other parameters. In the prior art, the basket is usually rotatably supported at the outlet about an axis parallel to the axis of rotation of the drum and adjusted on the inlet side by both sides, driven by a rotatable shaft eccentric and a (manual or power-operated) drive, as in DE 1 058 779 B based on a Tangentialdreschwerks and described in DE 2 132 217 C2 based on a Axialdresch- and separation rotor.
    Problem.
    In the prior art is to be regarded as disadvantageous that the shaft for the eccentric extends below the basket, i. in a place where relatively little space is available. solution
    The present invention is defined by the claims.
    An adjusting arrangement for adjusting the working gap of a basket arranged between two walls of a threshing and / or separating device comprises a first, in a variable manner about a first axis with respect to a first wall pivotally mounted Flebel. The first lever is pivotally coupled about a third axis to a second lever pivotally mounted to the second wall by a fourth axis pivotally connected to the first lever by a second axis connected to a connecting member. The axes all extend parallel to each other and parallel to the wall. The connecting element is displaceably mounted on the basket in a direction extending transversely to the walls, so that the connecting element moves in its displacement direction relative to the basket and simultaneously with the basket in the adjustment direction when the first lever is adjusted.
    In other words, the two levers with the connecting element and the walls (and other, the walls coupled to each other cross-connections) form an adjustable parallelogram, one side of which is formed by the connecting element. The side of the parallelogram opposite the connecting element is formed by the walls and their cross-connection. The remaining sides of the parallelogram are the two levers. Now, when a lever is adjusted, either by hand or by an actuator, the parallelogram moves in itself, which causes the connecting element to approach the axes, with which the levers are hinged to the side walls, or away from it. The basket then moves with the connecting element parallel to the walls, while the connecting element moves with respect to the basket.
    Preferably, the levers extend at least approximately parallel to the direction of adjustment of the basket.
    In one possible embodiment, the basket is hinged on the outlet side about a pivotally extending to the wall, fifth axis on the walls. To compensate for the adjustment of the rotation of the levers relative to the basket and the side walls about an axis parallel to the fifth axis, the first and fourth axes and / or the second and third axes may comprise elastic elements therein.
    The adjusting arrangement described can serve to adjust the working gap (threshing or separating gap) of a tangential threshing unit or a tangential separator. It can also adjust the working gap (threshing or separating gap) of an axial threshing and / or separating rotor.
    Working Example
    In the drawings, an embodiment of the invention described in more detail below is shown. It shows:
    1 is a schematic side view of a combine harvester with a multi-drum thresher,
    Fig. 2 is an enlarged, schematic side view of the separation basket of Mehrtrommeldreschwerks-combine harvester of Figure 1 with its adjustment, and
    Fig. 3 is a vertical, viewed from the front view of the separation basket of Figure 2 with its adjustment.
    1 shows a self-propelled combine harvester 10 with a frame 12 which is supported by driven front wheels 14 and steerable rear wheels 16 on the ground and is moved away from them. The wheels 14 are rotated by means not shown drive means in rotation to the combine 10 z. B. to move over a field to be harvested. In the following, directional details, such as front and rear, refer to the direction of travel V of the combine harvester 10 in the harvesting operation.
    At the front end portion of the combine harvester 10, a crop gathering device 18 is detachably connected in the form of a cutter to harvest harvested crops in the form of crops or other threshable culottes from the field and feed them up and down by a feeder 20 to a multi-drum threshing unit. the - in the direction of travel V arranged one behind the other - a threshing drum 22, a stripping drum 24, a superseding working conveyor drum 26, a separating drum 28 and a turning drum 30 includes. Downstream of the turning drum 30 is a straw shaker 32. The threshing drum 22 is surrounded by a concave 34 in its lower and rear area. Below the conveyor drum 26 is provided with openings or closed cover 35, while above the conveyor drum 26 is a fixed cover and below the separator drum 28 is a basket 36 with adjustable finger elements. Below the turning drum 30, a finger rake 38 is arranged.
    Below the multi-drum thresher is a front conveyor floor 40. A rear conveyor floor 42 is disposed below the straw walker 32. The conveying trays 40, 42 transport the mixture of grain, short straw and chaff to a cleaning device 46. Grain cleaned by the cleaning device 46 is fed by means of a grain screw 48 to an elevator, not shown, which transports it into a grain tank 50. A tailing auger 52 returns unmanaged ear parts through another elevator, not shown, back into the threshing process. The chaff may be ejected at the rear of the screen by a rotating chaff spreader, or it may be discharged through a straw chopper (not shown) disposed downstream of the straw walker 32. The cleaned grain from the grain tank 50 may be unloaded by a discharge system with cross augers 54 and a discharge conveyor 56.
    The systems mentioned are driven by means of an internal combustion engine 58 and controlled and controlled by an operator from a driver's cab 60. The various devices for threshing, conveying, cleaning and separating are located within the frame 12. Outside the frame 12 is an outer shell, which is largely hinged.
    2 shows an enlarged view of the separating drum 28 with the basket 36. It comprises in a conventional manner lateral cheeks 62, between which separating strips 64 extend. The basket 36 is hinged in its rear outlet area about an axis 66 pivotally on side walls 68, 68 'of the frame 12 (see Figure 3), which extends horizontally and transversely to the direction of travel V and hereinafter referred to as the fifth axis 66. Bearings with axes 66 are provided on both sides of the basket 36.
    In the front inlet area, a total of 70 marked adjustment arrangement is arranged, which serves to adjust the separation gap of the separation basket 36, i. to pivot it about the axis 55 in order to adjust the release effect to the respective crop characteristics.
    Reference is now made to FIG. The adjustment arrangement 70 comprises a first Flebel 72 arranged outside a first lateral wall 68 and a second Flebel 74 arranged outside a second lateral wall 68, which are coupled to one another by a rod-like connecting element 76. The first lever 72 is pivotally coupled by a first axis 78 to a bracket 80 mounted on the outside of the first wall 68 on the right. A second axis 82 connects the first lever 72 to the connector 76 which extends through apertures 106 in both lateral walls 68, 68 'and also through apertures 108 in the cheeks 62. The connector 76 is thus opposite the basket 36 in lateral Slidably mounted direction and is located directly on the edges of the openings 108 in the cheeks 62, while the openings 106 in the walls 68 as arcuate, concentric with the axis 66 slots are made to allow adjustment of the connecting member 76 in the direction of the arrow 102 , The second lever 74 is pivotally mounted about a third axis 84 on the connecting element 76 and about a fourth axis 86 pivotally mounted on a bracket 88, which in turn is attached to the left-hand, second wall 68 '. The basket 36 is located between the walls 68, 68 '.
    The axes 78, 82, 84 and 86 all extend parallel to each other and parallel to the walls 68, 68 '. As shown in Figure 2, the axes 78, 82, 84 and 86 (when viewed from the side) extend transversely to the longitudinal extent of the levers 72, 74. This extends in Figure 2 obliquely backwards and upwards.
    The adjustment assembly 70 forms an adjustable parallelogram, as shown in the figure 3. An adjustment drive of any kind, which is operated either manually by the operator or with a power-operated, influenced by an automatic or manually controlled control actuator (not shown), moves an adjusting rod 90, which is about a sixth axis 92, to the axes 78th , 82, 84 and 86 is parallel, hinged to the first lever 72, along the direction of the arrow 94. As a result, the first lever 72 pivots in the direction of the arrow 96, resulting in a movement of the connecting member 76 in the longitudinal direction in the direction of the arrow 98th leads, which in turn pivots the second lever 74 in the direction of the arrow 100. The movement of the levers 72, 74 also causes a (vertical) movement of the connecting element 76 and thus of the separating basket 36 in the direction of the arrow 102, i. an adjustment of the Arbeitsspaites the separation basket 36. This movement of the separation basket 36 is approximately parallel to the longitudinal extent of the lever 72, 74, as can be seen from an overall view of Figures 2 and 3. It would also be conceivable to provide an angle between the movement of the separation basket 36 and the longitudinal extent of the levers 72, 74, i. the levers 72, 74 and axles 78, 82, 84, 86 more to tilt from the rear or.
    As the basket 36 rotates about the fifth axis 66 when the lever 72 is moved, rotation of the levers 72, 74 in the plane of FIG. the axles 78, 86 rotate with respect to the brackets 80, 88 and / or the axles 82, 84 opposite the levers 72, 74. This movement could be compensated for by ball joints instead of the axles 78, 82, 84 and 86, or used in FIG elastic elements 104 made of rubber or the like in the axes 78, 86 on the one hand and / or the axes 82, 84 on the other. These elastic elements 104 may also serve to overcome load peaks resulting from stones or other foreign bodies or blockages without damage.
    An advantage of the adjusting arrangement 70 according to the invention is that the connecting element 76 extends through the separating basket 36, so that no additional elements of the adjusting arrangement 70 between the side walls 68, 68 'are required below the separating basket 36. An adjustment arrangement 70 shown in FIGS. 2 and 3 can also be used for the concave 34.
