    dde 0053 1 BE2020 / 0093 Field chopper with two-part transition housing Description The invention relates to a transition housing for attachment to a forage harvester, which has a supporting frame that can be moved in a forward direction over a field, a chopping drum for shredding harvested material picked up by means of a header, a ejection accelerator arranged downstream of the chopping drum, which comprises a housing and a rotor arranged therein, as well as an ejection chute for transferring the chopped crop onto a transport vehicle, the transition housing being attached or attachable in a crop-carrying position downstream of the housing of the ejection accelerator and upstream of the ejection chute, as well as a forage harvester equipped with it.
    State of the art Forage harvesters are used to harvest plants that are picked up or cut off from a field, fed to a chopping device and chopped up by it, and finally loaded onto a transport vehicle.
    For this task, a driven ejection accelerator is provided downstream of the chopping device (or a conditioning device that can optionally be introduced into the crop flow during maize harvesting downstream of the chopping device), which conveys the chopped crop upwards into a transition housing.
    At the upper end of the transition housing, a rotating ring is mounted on a rotating ring about the vertical axis or an axis slightly inclined backwards.
    Actuators are provided in order to rotate the lower part about the vertical axis and to rotate the upper part with respect to the lower part about the horizontal axis. Another actuator is used to adjust the discharge flap.
    In the prior art, the mechanical support of the discharge spout takes place via the transition housing, which is permanently coupled to the frame of the forage harvester. For this purpose, reference is made, for example, to EP 2 708 109 A1, which shows brackets welded to the transition housing, which are connected to the actual, supporting frame of the forage harvester via struts. The forces exerted by the discharge spout are therefore transmitted to the frame via the turntable, the transition housing and the struts. Since these forces can be relatively large, especially in the case of longer discharge chutes, the transition housing must be of sufficiently stable construction and is therefore very difficult and expensive to manufacture. Removing the transition housing - designed as a load-bearing part - is very time-consuming, because the discharge spout must first be dismantled before the transition housing can be removed from the frame of the forage harvester.
    EP 0 672 339 A1 shows another forage harvester in which the housing of the ejection accelerator, designed as a radial fan with an axis of rotation inclined backwards and downwards, is attached to a frame structure. The housing of the ejection accelerator is coupled to a tubular fan outlet, which is connected at its upper end to a radially outwardly projecting ring. The ring is loosely received on a base plate, but not attached to it. The gap between the ring and the base plate is closed by a rubber seal. The base plate is in turn connected by cross struts to struts of the frame of the forage harvester. The lower part of the discharge spout, designed as a tube, is rotatably supported on the base plate and is driven for adjustment around the vertical axis by a segmented gearwheel coupled to the tube, which interacts with a motor-driven worm. The tube is additionally supported at approximately half its height on a belt which is fastened to an upper transverse frame element which extends between vertical supports. At the upper end of the pipe, the upper part of the discharge spout is articulated so that it can pivot about a horizontal axis and is adjustable by a hydraulic cylinder. In this forage harvester, the function of the transition housing is performed by the tubular fan outlet. The tubular blower outlet does not have a load-bearing function, but is designed in a complex manner as a one-piece element.
    EP 1 618 777 A1 shows a forage harvester, on the transition housing of which an extension can be attached to the top in order to change the inclination of the axis of rotation of the discharge spout, and DE 1 213 158 B shows a forage harvester with an ejection tower which is in an open position at the rear displaceable flap is displaceable.
    OBJECT The object on which the invention is based is seen to be to provide a transition housing which is improved over the aforementioned prior art and which is easier to manufacture for a forage harvester and a forage harvester equipped therewith.
    Solution According to the invention, this object is achieved by the teaching of patent claims 1 and 8, the further patent claims citing features that further develop the solution in an advantageous manner.
    A transition housing for attachment to a forage harvester, which has a supporting frame that can be moved in a forward direction over a field, a chopping drum for chopping up crops picked up by means of a header, a chopping drum arranged downstream of the chopping drum
    Ejection accelerator, which comprises a housing and a rotor arranged therein, as well as an ejection chute for transferring the shredded crop onto a transport vehicle, the transition housing being attached or attachable in the crop-carrying position downstream of the housing of the ejection accelerator and upstream of the discharge chute, is made up of two of each other separable parts.
    The transition housing is thus in two parts, which makes it possible to assemble it from two parts that are easy to manufacture and can be manufactured in particular by a deep-drawing process. A design of the transition housing as a welded assembly would be conceivable, but is not absolutely necessary.
    The dividing line between the parts of the transition housing runs approximately vertically. Here, a front part of the transition housing is arranged in front of the rear part, or the separation takes place in a vertical plane extending in the forward direction, ie in a left and right part, which can, but not, be symmetrical to the vertical plane extending in the forward direction have to.
    The parts are fastened to one another in that a flange extending laterally and over the height of the transition housing is arranged on both sides of the front part, and one in the lateral direction and over the height on the two sides of the rear part of the transition housing extending flange is arranged and the flanges are screwed together. In the case of a separation extending in the forward direction, the flanges would similarly extend forwards or backwards and vertically.
    The front part and / or the rear part (or the left and right parts) of the transition housing can be curved in a concave manner. Here, the front part can be a flat,
    triangular surface, with the base of the triangle located at the lower edge of the front part and the other sides of the triangle extending to the upper edge of the front part and converging there, while the side surfaces of the front directly adjoining the 5 other sides of the triangle Some are curved in themselves. Analogously, the rear part can comprise a flat, triangular surface, with the base side of the triangle being at the lower edge of the rear part and the other sides of the triangle extending to the upper edge of the rear part and converging there, while those directly adjoining the other sides of the triangle adjoining side surfaces of the rear part are curved in itself. On the sides of the rear part can be provided in the forward direction extending, in itself flat side surfaces which adjoin the curved side surfaces outward and which narrow towards the top. The front part can narrow in the lateral direction from bottom to top and widen in the forward direction from bottom to top, while the rear part can narrow in the lateral direction from bottom to top and can remain about the same width in the forward direction from bottom to top. In the case of a separation extending in the forward direction, the two parts in assembled form would look exactly as described in the two previous paragraphs for the assembled parts separated transversely to the forward direction, the only difference being the differently arranged separation and the resulting modification of the assembly means.
    The discharge spout of the forage harvester can be mounted on a support that is coupled to the frame and independent of the transition housing, while the transition housing has no supporting function for the discharge spout.
    Exemplary embodiment An exemplary embodiment of the invention is explained with the aid of the figures.
    Show it:
    1: a schematic side view of a forage harvester, FIG. 2: a side view of the frame of the forage harvester of FIG. 1,
    3: a side view of the front area of the frame with the attachment means of the front wheels removed, FIG. 4: a perspective view of the transition housing, FIG. 5: a perspective view of the front part of the transition housing from the front, and FIG. 6: a perspective view of the rear part of the transition housing from the rear.
    A self-propelled forage harvester 10 shown in FIG. 1 is built on a frame 12 which is supported by driven front ground engaging means 14 in the form of wheels and rear ground engaging means 16 in the form of steerable wheels.
    The forage harvester 10 is operated from a driver's cab 18 from which a header 20 suitable for harvesting stem-like plants can be viewed.
    By means of the header 20, which in the illustrated embodiment is a row-independent maize header, material picked up from the ground, e.g. B.
    Corn, grain or the like is fed through upper feed rollers 30 and lower feed rollers 32 arranged in a feed assembly 36 to a chopper drum 22, which chops it into small pieces and delivers it to an ejection accelerator 24.
    The good leaves the
    Forage harvester 10 to a trailer traveling alongside via an adjustable discharge chute 26. Between the chopping drum 22 and the conveying device 24 extends a conditioning device 28 with two interacting rollers 38, 40 through which the material to be conveyed is tangentially fed to the discharge accelerator 24. In the following, directional information - unless otherwise mentioned - relate to the forward direction V of the forage harvester 10, such as front, rear, left and right, which runs from right to left in FIG. 1.
    Between the crop receiving device 20 and the chopping drum 22, the crop is transported by an intake conveyor with lower conveyor rollers 32 and upper conveyor rollers 30 which are mounted inside a intake housing 36. The conveyor rollers 30, 32 are also referred to as pre-press rollers, since the upper conveyor rollers 30 are biased against the lower conveyor rollers 32 by spring force so that the crop is precompacted between the conveyor rollers 30, 32 and can be better cut. The chopping knives distributed around the circumference of the chopping drum 22 cooperate with a shearbar to chop the material. Figures 2 and 3 show the frame 12 with the panels removed. The frame 12 comprises two longitudinal beams 42, only one of which can be seen. The other longitudinal beam extends laterally offset to the longitudinal beam 42 shown, parallel to the longitudinal beam 42 shown (or at a horizontal angle thereto) and is connected to the longitudinal beam 42 shown by cross connections. The longitudinal beams 42 can be designed as steel beams and have any desired profile (e.g. C, double-T or box profile). On the longitudinal beam 42, via fastening means (not shown), there are, among other things, a drive motor 44 arranged in the rear area of the forage harvester 10 for driving the movable components of the forage harvester 10 and, in front of it, a cooling unit 46 with heat exchangers and a fan for sucking in air (a possible embodiment is in DE 10
    2008 040 902 A1, the disclosure of which is incorporated by reference into the present documents) that sucks in air from a maintenance room 48. The side rail 42 extends from a rear end 54, which is near the rear end of the forage harvester 10, to a front end 52. At the rear end of the side rail 42 is a counterweight assembly 56 with an attached coupling 50 to the side rail 42 connected.
    In the rear third of the longitudinal beam 42, on its underside, attachment means 58 for attaching the rear ground engagement means 16 are attached, which comprises a hydraulic motor 60 for driving the ground engagement means and a transversely extending axle arrangement 64 with flanges 62 on both sides for attaching the rear ground engagement means 16. The axle arrangement 64 comprises in known means an optional drive train between the optional hydraulic motor 60 and the flanges 62 which are rotatable about their axis and which can be rotated about the vertical axis by steering means in order to specify the direction of travel of the forage harvester 10. One possible embodiment of the attachment means 58 is shown in DE 10 2013 222 254 A1, the disclosure of which is incorporated into the present documents by reference.
    Adjacent the front end of the side rail 42, attachment means 66 are provided for attaching the front ground engaging means 14, which include a mounting plate 68 that is positioned on the outside of the side rail 42 and bolted to the side rail 42. End drives 72, which in turn are equipped with rotatable flanges 70 for attaching the ground engaging means 14, are mounted on the fastening plate 68. The flanges 70 are drivingly connected via the final drives 72 to mechanical or hydrostatic or electrical drive means, which in turn can be driven by the drive motor 44. If the ground engaging means 14, 16, as shown in FIG. 1, are designed as wheels, the rims of the wheels are connected to the flanges 64, 70, as shown in FIG. Are the
    Ground engaging means, on the other hand, are designed as crawler tracks, a drive wheel of the crawler track is connected to the flange 64 or 70.
    The axis of rotation 74 of the flange 70 (and thus of the front ground engagement means 14) is located above the lower edge 78 of the area of the longitudinal member 42 adjacent to the axis of rotation 74, in particular approximately at the level of the upper edge 76 of the region of the longitudinal member 42 adjacent to the axis of rotation 74 The longitudinal member 42 rises linearly overall from the front to the rear, ie the upper edge 76 is lower at the front end 52 of the longitudinal member 42 than at the rear end 54, which also applies analogously to the lower edge 78. In addition, the longitudinal beam 42 tapers from the front to the rear, at least until just before the rear end 54, i.e.
    Lower edge 78 and upper edge 76 converge towards the rear.
    A holder 80 for attaching the chopping drum 22 is also provided at the front end of the longitudinal beam 42 and comprises a fastening plate 82 which is positioned on the inside of the longitudinal beam 42 and is screwed to the longitudinal beam 42. The fastening plate 82 extends forward over the front end 52 of the longitudinal member 42 and comprises a fork 84 at the front end, which is used to hold bearings for the chopping drum 22. The intake housing 36 is also rotatable about the axis of rotation of the chopping drum 22 in a manner known per se and is adjustably supported by a hydraulic cylinder not shown in the figures. The fork 84 is arranged at a height such that the axis of rotation of the chopping drum 22 is slightly above the upper edge 76 of the front region of the longitudinal member 42. The axis of rotation of the chopping drum 22 is also located in front of the front end 52 of the longitudinal member 42.
    The conditioning device 28 with the two rollers 38, 40 is located with the rear roller 40 above the area of the longitudinal member 42 adjacent to the front end 52, while the front roller 38 is located partially in front of the front end 52 in the forward direction V. The conditioning device 28 is designed as an assembly that can be removed as a whole from the crop channel, as is described, for example, in DE 10 2010 002 509 A1, the disclosure of which is incorporated into the present documents by reference. The rollers 38, 40 are driven by a belt 86 which is driven by a belt pulley coupled to the shaft of the ejection accelerator 24 and revolves around belt pulleys coupled to the rollers 38, 40 and a freely rotating belt pulley 88. In the operating position shown, the conditioning device 28 is indirectly supported on the longitudinal beam 42 via suitable means.
    A support 98 of a rotary bearing 90 of the discharge spout 26, which enables the discharge spout 26 to rotate about an exactly or approximately vertical axis, is supported by an auxiliary frame structure on the longitudinal member 42. The subframe structure includes a rear submount 94 which extends obliquely forward and upward from an attachment point 102 located approximately one quarter of the length of the side member 42 and is attached to the rear end of the support 98. In addition, a front auxiliary carrier 96 is provided, the lower end of which is fastened to the fastening plate 82 of the chopping drum 22. From the lower end, the front auxiliary carrier 96 first extends vertically upwards to approximately the level of the axis of rotation of the ejection accelerator 24, there then obliquely backwards and upwards and somewhat backwards the axis of rotation of the ejection accelerator 24 again steeply upwards and is with the front end of the support 98 connected. A horizontal carrier, to which the cabin 18 is fastened, can also be attached to the front auxiliary carrier 96, in particular in the vicinity of the axis of rotation of the ejection accelerator 24. The discharge spout 26 comprises a tubular lower part 106 which is supported on the support 98 by means of the rotary bearing 90 and which can be rotated about the vertical or slightly rearwardly inclined axis by means of an adjusting drive (not shown), as well as an upper part 108 which is actuated by an actuator 110 is pivotable relative to the lower part 106 about a horizontal axis. An actuator-adjustable discharge flap 112 is attached to the outer end of the discharge spout 26.
    A transition housing 92 is also attached to the frame 12 and extends between the housing 104 of the ejection accelerator 24 and the lower end of the ejection spout 26 and serves as a channel for the chopped crop downstream of the ejection accelerator 24. The axis of rotation of the ejection accelerator 24 is connected to the front auxiliary carrier 96 via a holder 100. The housing 104 of the ejection accelerator 24 is also fastened to the holder 100. It should be noted that a further subframe construction with sub-beams 94, 96 is attached to the other longitudinal beam, which is not shown in the figures. These auxiliary carriers 94, 96 are connected to one another by the support 98. Brackets 100 are also attached to both auxiliary carriers 96 and both sides of the ejection accelerator 24, which also applies analogously to the attachment means 66 and the bracket 80. All means mentioned here are mirror-symmetrical to the vertical longitudinal center plane of the forage harvester 10. The drive of the chopping drum 22 and the ejection accelerator 24 takes place in the embodiment shown in a manner known per se via a further belt which can be driven via a gear driven by the drive motor 44, including reference is made to the disclosure of EP 2 269 439 A1, which is incorporated into the present documents by reference.
    The transition housing 92 is shown in more detail in FIGS. It comprises a front part 114 and a rear part 116. The dividing line between the two parts 114, 116 extends approximately vertically, along the direction of the crop flow. Both parts 114, 116 are concave in shape.
    The front part 114 comprises a flat surface 118 which is triangular in shape, the base side of the triangle being at the lower edge of the front part 114 and the other sides of the triangle extending to the upper edge of the front part 114 and converging there. The remaining side surfaces 120, 122 of the front part 114, which laterally adjoin the other sides of the triangle, are curved in an approximately circular manner. Flanges 124 are arranged on the sides of the front part 114 and extend over the entire height of the front part 114 and serve for connection to the rear part 116. Overall, the front part 114 narrows in the lateral direction from bottom to top and widens in the forward direction V from bottom to top.
    The rear part 116 comprises a flat surface 126 which is triangular in shape, the base side of the triangle being at the lower edge of the rear part 116 and the other sides of the triangle extending to the upper edge of the rear part 116 and converging there. The side surfaces 128, 130 directly adjoining the other sides of the triangle are curved in an approximately circular manner. On the sides of the rear part 116 are provided, which extend in the forward direction V, are flat side surfaces 134 which adjoin the curved side surfaces 128, 130 towards the outside and which narrow towards the top. Flanges 132, which extend over the entire height of the rear part 116 and serve to connect to the rear part 116, are arranged on the side surfaces 134. Overall, the rear part 116 narrows in the lateral direction from bottom to top and remains approximately the same width in the forward direction V from bottom to top.
    In the embodiment shown, the flanges 124, 132 are designed as separate angles that are connected (e.g. welded or screwed or riveted or glued) to the rear or front part 114, 116. The side surfaces of the flange 132 become narrower, analogously to the side surfaces 134,
    from the bottom up. The flanges 124, 132 could also be represented in one piece with the parts 114, 116.
    In the rear part 116, an optional maintenance opening 136 is provided in the flat surface 136, which is closed during operation by a cover 142 (see FIG. 3).
    The attachment of the transition housing 92 to the housing 104 of the fan 24 takes place by means of flanges 138 protruding upwards from the housing 104, which are secured by screws 140, which are screwed through corresponding holes 144 in the underside of the parts 114, 116, or in any other way. At its upper end, the transition housing 92 can be pushed into a complementary opening in the support 98 and fixed in a form-fitting manner in both horizontal directions without a fixed mechanical coupling in the vertical direction having to take place. An inherently flexible seal can also be installed between the support 98 and the transition housing 92. However, a rigid mechanical coupling of the transition housing 92 to the support 98 would also be conceivable.
    The transition housing 92 can be further supported on a transverse support, not shown in the figures, which extends above the housing 104 of the ejection accelerator 24 between the two auxiliary supports 94 or 96 laterally and / or between the auxiliary supports 94 and 96 in the forward direction V.
    The support of the discharge chute 26 on the longitudinal members 42 of the frame 12 is carried out via the pivot bearing 90, the support 98 and the subframe construction with the auxiliary carriers 94 and 96, while the transition housing 92 is relieved of a load-bearing function for the discharge chute 26. Since the transition housing 92 does not have to absorb any or only small forces, it is not necessary to design it as a complex welded assembly and it is possible to design it as a wear part and to dispense with wear inserts.
    It can thus also be manufactured inexpensively from plastic.
    The two-part embodiment makes it possible to manufacture the transition housing 92 in a simple and inexpensive manner from deep-drawn parts 114, 116, be they made of plastic or metal or any material such as metal with a wear-resistant coating, especially in the areas that are particularly strong compared to the remaining areas are affected by abrasion, or a continuous wear-resistant coating.
    The expansion of the transition housing 92 from the
    Forage harvester 10 can be done with the transition housing 92 not dismantled, or the rear part 116 accessible from the maintenance space 48 is first removed and, if necessary, the front part 114,
