    Conveying disc for a conveying rotor for crop conveying in an agricultural harvester
    description
    The invention relates to a conveyor disc for a conveyor rotor for Emtegutförderung in an agricultural harvester.
    BACKGROUND ART Conveyor rotors are used in various agricultural harvesting machines, for example in baling presses or loading wagons for crop conveying downstream of a pickup (cf., for example, DE 100 17 984 A1) or in combines as conveyors in a multi-drum threshing mechanism (see DE 10 2012 204 416 A1). Such conveyor rotors comprise a number of conveyor discs, around the circumference of which a plurality of tines are distributed.
    The conveyor discs are positively coupled in the prior art for transmitting torque in a tangential (i.e., circumferential) direction to a central, non-circular shaft on which a plurality of conveyor discs are slid. In the axial direction, the fixation by tie rods, which extend through holes in the conveyor discs (DE 10 2012 204 416 A1) or by areas of the conveyor discs, which penetrate into complementary openings of the shaft (DE 100 17 984 A1).
    Since the required for Erntegutförderung torque transmission takes place in the tangential direction by the mentioned form fit between the shaft and the conveyor disc, the shaft must be relatively thick-walled and thus difficult to be able to transfer the required torque reliable.
    DE 43 21 898 C2 shows a grain processor roller for Emtegutnachbearbeitung in a forage harvester, which is composed of several successive in the axial direction shell parts. The shell parts have on their peripheral surface a sharp-edged profiling, which serves to unlock the grains in Emtegut. The outer shell parts are coupled with support disks, to which stub shafts are attached. The connection of the shell parts with each other is effected by axially extending
    Clamping screws that extend through aligned holes in the shell parts and clamp the shell parts with each other. Adjacent shell parts engage one another in a form-fitting manner at the ends by being provided with complementary circumferential grooves and shoulders. This eliminates a central shaft and the torque transmission between the shell parts is due to their tension through the clamping screws - by adhesion. The transferable in this way torques are not particularly large, so they may be sufficient for the intended application in the Kömerprozessorwalze, but would be too low for a conveyor rotor.
    task
    The present invention has set itself the task of providing a conveyor disc and a conveyor rotor, which does not have the mentioned disadvantages or to a lesser extent.
    invention
    The present invention is defined by the claims.
    A conveyor disc for a conveyor rotor for Emtegutförderung in an agricultural harvester has a first side surface and a second side surface. To the circumference of the conveyor disc concentric tines for the promotion of crop are distributed to a central, to the side surfaces orthogonal axis of rotation of the conveyor disc. On the side surfaces features for positive torque transmission from the conveyor disc to an adjacent conveyor disc available.
    In other words, the side surfaces of adjacent conveyor discs are positively coupled with each other by the features torque transmitting. In this way, a central shaft is unnecessary for the transmission of torque, although it would be conceivable to provide a (weaker and thus lighter) shaft that transmits only part of the torque on the conveyor discs, while the other part of the torque through the positive features be transferred from a conveyor to their neighbor. For fixing the conveyor discs in the radial and / or axial direction could also serve an axle that transmits no torque. The positive torque transmission takes place according to the present invention between the conveyor discs at a greater distance from the axis of rotation than would be possible with a shaft, so that due to the larger lever arm for a given torque to transmit smaller forces than before, which allows the features relatively small.
    The specific embodiment of the features for positive torque transmission from the conveyor disc to an adjacent conveyor disc is within the scope of the invention underlying the idea arbitrary. Thus, it would be conceivable to provide the side surfaces of the conveyor disc with a circumferential or partially circumferential toothing, which engages in each case in a complementary toothing of an adjacent conveyor disc. In another embodiment, it is conceivable to provide the conveyor disc with an axial bore into which a separate pin or the like. penetrates, which also penetrates through a hole in the adjacent conveyor disc. Preferably, at the first side surface at a distance from the axis of rotation of the conveyor disc in the axial direction over the side surface outwardly projecting, circumferentially only over a portion of the circumference of the conveyor disc extending element attached, while on the second side surface at a distance from the axis of rotation of the conveyor disc a recess extending in the axial direction is provided, which extends in the circumferential direction only over part of the circumference of the conveyor disc. The element of a conveyor disc can thus be introduced into the recess of the adjacent conveyor disc, so that the element and the recess then form the features for positive torque transmission from the conveyor disc to an adjacent conveyor disc.
    The element and the recess align the adjacent conveyor discs preferably also due to a radial fit in the radial direction with each other.
    In particular, the recess is complementary to the element, so that an element of a first conveyor disc can be introduced to transmit torque in a recess of an adjacent, second conveyor disc. It should be noted, however, that it would also be conceivable that the element of a conveyor disc penetrates into a recess in an intermediate ring arranged between the conveyor discs, which in turn has an element which penetrates into the recess of the next conveyor disc. In this embodiment, the element and the recess of a single conveyor disc need not necessarily be complementary to each other (but may have different
    Dimensions, shapes and / or distances from the axis of rotation), since then the recess and the element of the intermediate ring can make the complementarity and thus the fit.
    On one or both side surfaces of the conveyor disc concentric spacer rings can be arranged to the axis of rotation of the conveyor disc, while the element and / or the recess is then mounted in particular on the spacer ring or are. This saves you separate intermediate rings and the effort required to attach them when assembling the conveyor rotor.
    It is also advisable, in each case several elements and wells equidistant from each other and to distribute concentric to the axis of rotation of the conveyor disc on the side surfaces. As a result, on the one hand, the torque is distributed over a larger number of elements and depressions, on the other hand, it is also possible to align adjacent (especially mutually identical) conveyor discs in the circumferential direction differently, which allows the tines of the conveyor discs of the conveyor rotor in a (known per se) To arrange spiral shape.
    The conveyor disc can be provided with one or more, equidistantly distributed axial openings. Through this opening or openings, the conveyor rotor in the axial direction fixing clamping anchors or rods can be inserted.
    At both axial ends of the conveyor rotor end axle or stub shaft can be attached.

    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 driving means to drive the combine 10 e.g. to move over a field to be harvested. In the following, directional details, such as from the rear and the rear, relate to the direction of travel V of the combine harvester 10 in harvesting operation. The combine harvester 10 shown is an application example of the conveying rotor 30 according to the invention, which could also be used on other types of harvesting machines, in particular as a loading rotor in a baling press or a loading wagon.
    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. which - arranged one behind the other in the direction of travel V - comprises a threshing drum 22, a stripping drum 24, a conveyor rotor 30 operating with superficial action, a separating drum 28 and a discharge conveyor 26. Downstream of the discharge conveyor 26 is a straw shaker 32. The threshing drum 22 is surrounded by a concave 34 in its lower and rear regions. Above the conveyor rotor 30 is a fixed cover and below the Abscheidetrommel 28 a separating basket 36 with adjustable finger elements. Below the unterzuschächtig conveying discharge conveyor 30, a separation grate 38 is arranged. A scraper 35 is upstream on the discharge side below the conveyor rotor 30 the inlet region of the separation drum 28. The Abscheididekorb 36 is in its central region with conventional scraper blades 37 and in its on and
    Outlet area equipped with finger rake 39.
    The conveying rotor 30 is shown in FIG. 2 in a perspective view. It comprises a number (thirty in the illustrated embodiment) conveyor disks 66 and end disks 78 disposed at the axial ends. The end disks 78 are each coupled to flange plates 74 which in turn comprise a stub shaft 68 at one end and a stub axle 84 (see Figure 7). wear at the other end. The conveyor discs 66 each include five tines 40 distributed around its circumference, although more or fewer tines 40 could be used. The prongs 40 are approximately triangular with radially outer ends 72 and circumferentially symmetrical about a radial centerline. The tines 40 of adjacent conveyor discs 66 are arranged angularly offset relative to each other, so that the outer ends 72 of the tines 40 of the conveyor rotor 30 each lie on one of a total of five imaginary coils. The conveyor discs 66 are spaced apart by spacer rings 70, which are each formed integrally with the conveyor discs 66, see. FIGS. 3 and 4.
    Figures 3 and 4 show a conveyor disc 66 in a perspective view from its two sides. As already noted, the conveyor discs 66 are made flat in themselves, with a central, circular opening, around which the tines 40 are distributed equidistantly in the circumferential direction. The spacer rings 70 are integrally formed (e.g., cast or deep-drawn) on either side surface of the conveyor disc 66 or attached thereto, e.g. by welding. On the right-hand side surface of the conveyor disc 66 four axially extending recesses 82 are introduced with approximately rectangular cross-section in the spacer ring 70, which are distributed in the circumferential direction equidistantly around the spacer ring 70. On the left side surface of the conveyor disc 66 shown on the spacer ring 70 four axially extending, projecting elements 80 are mounted with approximately rectangular cross-section, which are distributed equidistantly in the circumferential direction around the spacer ring 70 and aligned with the recesses 82 in the circumferential direction. This achieves that the protruding elements 80 of a conveyor disc 66 can be inserted into the recesses of the respectively directly adjacent conveyor disc 66, as shown in FIG. Then, the elements 80 and the recesses 82 fix the adjacent conveyor discs 66 in the circumferential direction, i. they transmit the torque to drive the conveyor rotor 30 from one conveyor disc 66 to the next, and simultaneously lock the conveyor discs 66 in the radial direction to each other. The division of elements 80 and recesses 82 allows adjacent conveyor discs 66 to be angularly spaced together to achieve the helical shape of the ends 72.
    The end plates 78 are, as shown in Figure 5, provided with projecting portions 76 which plates with complementary portions in the flange 74, as can be seen in Figure 2
    The axial fixation of the conveying rotor 30 is effected, as shown in FIG. 7, by two clamping anchors 86, which are screwed to flanges of the stub shaft 68 and a stub axle 84. The clamping anchors 86 extend through the central opening of the conveyor discs 66.
    As a result, the torque transmission from the stub shaft 68 via the flange plate 74 takes place on the drawn in Figure 2 right end plate 78 and from there via the mounted on the side surfaces of the conveyor discs 66 elements 80 and recesses 82. A relatively heavy shaft for torque transmission is unnecessary. The clamping anchors 86 only provide the axial fixation of the conveyor rotor 30, but do not serve appreciably for torque transmission.
