    The invention relates to a forage harvester with a supporting frame that can be moved in a forward direction over a field, a drive motor, a chopping drum for shredding harvested material picked up by means of a header, a conditioning device arranged downstream of the chopping drum, a downstream of the Conditioning device arranged ejection accelerator, as well as an ejection chute arranged downstream of the ejection accelerator, wherein the supporting frame has at least one longitudinal member to which the drive motor, the chopping drum, the conditioning device, the ejection accelerator, the discharge chute and attachment means for front and rear ground engagement means are attached directly or indirectly the side member extends in the forward direction from a rear end adjacent to the rear end of the forage harvester to a front end extends and the conditioning device is at least partially arranged above the side member.
    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 drum 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 drum (or a conditioning device that can optionally be introduced into the crop flow during maize harvesting downstream of the chopping drum), which feeds the chopped crop upwards
    Transition housing promotes. At the upper end of the transition housing, a rotating ring around the vertical axis or an axis slightly inclined backwards is mounted on a lower part of an ejection chute, on which the upper part of the ejection chute is mounted pivotably about a horizontal axis.
    The forage harvester is built on a supporting frame to which, among other things, a drive motor, the chopping drum, the conditioning device, the discharge accelerator and the discharge spout are attached directly or indirectly, i.e. via supporting intermediate elements. The frame usually comprises two laterally spaced apart longitudinal members which are connected to one another by cross members and which extend over the length of the forage harvester. In the rear area of the side members, the drive motor is attached at the top, while the chopping drum is attached in the front area. The conditioning device, the ejection accelerator and the discharge chute are connected to the side members in a supporting subframe structure.
    In current forage harvesters, the rear and front axles are arranged below the one-piece longitudinal beam extending from the rear end of the forage harvester to the axis of rotation of the chopping drum and are connected to the longitudinal beam by welded structures. The axis of rotation of the chopping drum is usually attached at the level of the longitudinal beam at its front end and approximately at the same height, see DE 32 43 819 A1, EP 2 574 230 A1, EP 3 449 714 A1, or by means of a separate welded construction which adjoins the longitudinal beam towards the front, positioned above the level of the longitudinal beam, while the front axle, which is also attached to the separate welded construction, is arranged below the level of the longitudinal beam, as in the other documents mentioned (EP 0 672 339 A1).
    Object of the invention
    In the embodiments in which it extends forward to below the conditioning device (as shown in DE 32 43 819 A1, EP 2 574 230 A1, EP 3 449 714 A1), the longitudinal support is available for installing the grain processor standing room down. Its position is defined by the front axle attached to its underside. At the moment, however, there is a tendency towards conditioning devices with ever larger roller diameters, so that it would be desirable to enlarge the installation space for accommodating the conditioning device.
    Solution According to the invention, this object is achieved by the teaching of patent claim 1, the further patent claims citing features that further develop the solution in an advantageous manner.
    A forage harvester is proposed with a supporting frame that can be moved in a forward direction over a field, a drive motor, a chopping drum for shredding harvested material picked up by means of a header, a conditioning device arranged downstream of the chopping drum, an ejection accelerator arranged downstream of the conditioning device, and a Downstream of the ejection accelerator arranged discharge chute, wherein the load-bearing frame has at least one longitudinal member to which the drive motor, the chopping drum, the conditioning device, the discharge accelerator, the discharge chute and attachment means for front and rear ground engaging means are attached directly or indirectly and the longitudinal member is attached along the forward direction extends forward from a rear end adjacent to the rear end of the forage harvester to a front end and the conditioning device at least partially o above the
    Side member is arranged. The axis of rotation of the front ground engaging means lies above the adjacent lower edge of the side member.
    In other words, the axis of rotation of the front ground engagement means, which can be wheels or caterpillars rotating around the axis of rotation, the drive axis of which corresponds to the axis of rotation, is no longer - as in the prior art - arranged below the longitudinal beam, but the longitudinal beam is after lowered at the bottom so that the axis of rotation is located above the lower edge of the longitudinal member, in particular at the level of the upper edge of the longitudinal member adjacent to them. In this way, new installation space is created to accommodate the conditioning device, which is at least partially located above the longitudinal beam (i.e. not only higher than the longitudinal beam, but also located in the forward direction above the longitudinal beam), and the components following it in the crop flow direction ( Ejection accelerator and discharge spout) so that one or more of these components can be made larger than before for a given maximum height of the forage harvester in order to extend their service life and / or improve their function.
    The axis of rotation of the front ground engaging means can be located in front of the front end of the side member.
    The upper edge and / or lower edge of the side member can rise upwards towards the rear.
    The vertical dimension of the side member can decrease or increase towards the rear or remain the same.
    The frame can comprise two side members arranged side by side and connected to one another.
    The attachment means for the front ground engaging means can comprise a fastening plate connected to the longitudinal beam, on which a flange for attaching a ground engaging means is rotatably supported. 5 The chopping drum can be attached to a bracket, which in turn is connected to the longitudinal beam. The axis of rotation of the chopping drum can be located above the upper edge of the longitudinal beam and / or in front of its front end.
    The drive motor and / or the conditioning device and / or a cooling unit can be arranged at least partially directly above the upper edge of the longitudinal member. It is thus possible to use the installation space resulting from the described shifting of the longitudinal member downwards (compared to the prior art) to accommodate components of the forage harvester by shifting these components downwards and / or enlarging them. Exemplary embodiment An exemplary embodiment of the invention is explained with the aid of the figures. The figures show: FIG. 1: a schematic side view of a forage harvester, FIG. 2: a side view of the frame of the forage harvester of FIG. 1, and FIG. 3: a view of the front area of the frame with the attachment means of the front wheels removed. A self-propelled forage harvester 10 shown in FIG. 1 is built on a frame 12, which is driven by driven front ground engagement means 14 in the form of wheels and rear ground engagement means 16 in the form of steerable
    Wheels is carried. 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 pre-press rollers 30 and lower pre-press rollers 32 arranged in a feed assembly 36 to a chopping drum 22, which chops it into small pieces and gives it to an ejection accelerator 24. The crop leaves the forage harvester 10 to a trailer driving alongside via an adjustable discharge spout 26. A conditioning device 28 with two co-operating rollers 38, 40 extends between the chopping drum 22 and the conveyor 24, through which the material to be conveyed is transferred to the discharge accelerator 24 is fed tangentially. 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 member extends laterally offset from the longitudinal member shown
    42 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, among other things, via fastening means (not shown), 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. If, on the other hand, the ground engaging means 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 of 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 beam 42. The conditioning device 28 with the two rollers 38, 40 is located with the rear roller 40 above the area of the longitudinal beam 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 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.
    A transition housing 92 is also attached to the support 98 and / or to the housing 104 of the discharge accelerator 24, which extends between the housing 104 and the lower end of the discharge spout 26 and serves as a channel for the chopped crop downstream of the discharge 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.
    In the embodiment shown, the chopping drum 22 and the ejection accelerator 24 are driven in a manner known per se via a further belt which can be driven via a gear unit driven by the drive motor 44, for which reference is made to the disclosure of EP 2 269 439 A1, which is provided by Reference is included in the present documents.
    After all of this, it can be seen that the described positioning of the axis of rotation 74 of the flange 70 (and thus the front ground engaging means 14) above the lower edge 78 of the
    The area of the longitudinal beam 42 adjacent to the axis of rotation 74, which is advantageously one-piece, since no separate welded construction is required in the front area of the forage harvester 10, there is an enlarged installation space available for accommodating the conditioning device 28 compared to the prior art. Some components, such as drive motor 44, cooling unit 46 and conditioning device 28 with rollers 38, 40 can thus be moved downwards and / or enlarged compared to the prior art. As a result, the center of gravity of the forage harvester 10 is also shifted downwards.
    The diameter of the rollers 38, 40 can thus be, for example, 30 cm or more. It would also be possible to arrange the rollers 38, 40 even lower than shown in FIG. Another advantage of the longitudinal members 42 shown is that due to the rearwardly rising upper edge 76 - given the height of the upper edge of the cooling unit 46 - the cooling unit 46 can also be higher than before. The rearwardly converging upper and lower edges 76, 78 of the longitudinal members 42 enable weight savings, because the vertical dimensions of the longitudinal members 42 are adapted over their length to the loads to be absorbed and decreasing towards the rear. Finally, different longitudinal members 42 can be used for different constructions of the forage harvester 10, which are in particular equipped with drive motors 44 of different powers, whereby the other components of the frame 12 can remain the same and thus the number of components to be provided is kept low.
