    Infeed
    The invention relates to a feed mechanism for an agricultural machine, in particular for a forage harvester.
    DE 10 2009 043 704 A1 discloses a chopper unit of a forage harvester with a feed mechanism. The feed mechanism has a feed housing with opposite side walls. The feed mechanism furthermore has feed rollers forming pairs of feed rollers, the axes or shafts of which extend through recesses in the side walls of the feed housing. According to DE 10 2009 043 704 A1, the feed rollers form two pairs of feed rollers, a chopper drum being positioned behind the feed roller pairs when viewed in the direction of crop flow.
    Another feed mechanism for an agricultural machine, in particular for an agricultural harvester designed as a forage harvester, is known from DE 10 2013 112 326 A1. This feed mechanism also has a feed housing with opposite side walls. Furthermore, the feed mechanism comprises at least two feed rollers forming pairs of feed rollers. Axles from first, upper feed rollers of the feed roller pairs extend through recesses in the side walls, namely in such a way that the axes can be displaced within the recesses in order to allow a relative movement of the first, upper feed rollers to second, lower feed rollers of the feed roller pairs. The first, upper feed rollers of the feed roller pairs are coupled via axle links and connected to the side walls of the feed housing of the feed unit via a connecting link.
    In operation, crop can settle in the recesses in the side walls of the feed housing, in which the axes of the first feed rollers can be displaced. Fixing the crop in these recesses BE2017 / 5639 can affect the relocation of the first feed rollers. Furthermore, seals on roller gears can be damaged.
    In order to prevent crops from penetrating into recesses in the side walls of a feed mechanism, it is known from EP 2 485 577 B1 to assign thread-like or fibrous strands, strands, threads or fibers to the recesses, which extend transversely to a longitudinal axis of the recesses and one Form the type of brush seal.
    From DE 37 17 581 A1 a shredding machine with a shredding rotor and feed rollers is known. Shafts or axes of the feed rollers can move in movement openings of side walls of a channel, with cover plates which partially cover the movement openings being assigned to the side walls of the channel on each side.
    There is a need for a feed mechanism for an agricultural machine in which the penetration of crop into the recesses in the side walls of the feed housing, in which the axes of the feed rollers can be displaced, can be prevented simply and reliably. The present invention has for its object to provide a novel feed mechanism.
    This object is achieved by a feed mechanism according to claim 1. In the feed mechanism according to the invention, at least one side wall is assigned a flat cover element for partially covering at least some of the recesses in the side wall, depending on the relative position of the first feed rollers relative to the second feed rollers. The respective flat cover element extends parallel to the respective side wall and can be displaced relative to the respective side wall and thus relative to the recesses of the respective side wall by an instantaneous pole lying outside BE2017 / 5639 half of the respective cover element, the instantaneous pole of the respective flat cover element having an axis of rotation of the first End of the or each wishbone coincides. This can be easily and reliably prevented that crop material gets into the recesses in the side walls of the feed housing of the feed mechanism, in which axes of the first feed rollers, which can be displaced relative to the second feed rollers of the pairs of feed rollers, penetrate. The displaceability of the first feed rollers is not affected. Seals of roller gears are protected from damage.
    At least one drive shaft for the first feed rollers preferably extends through further recesses in the side walls of the feed housing in such a way that, coupled to the relative movement of the first feed rollers, it can be displaced in the further recesses of the side walls relative to second feed rollers. This is advantageous in order to prevent crops from penetrating into the recesses in the side walls through which a drive shaft for the feed rollers extends.
    According to an advantageous development of the invention, the respective flat covering element has at least one recess for the passage of the axis of the first feed rollers at least one of the pairs of feed rollers and preferably at least one further recess for the passage of the drive shaft for the feed rollers. Each of the recesses of the respective flat cover element corresponds to one of the recesses of the respective side wall in such a way that the axis or shaft of one and the same first feed roller or the drive shaft extends through corresponding recesses. The recesses on the respective flat cover element are preferably dimensioned such that the respective axes of the respective first feed roller and, if appropriate, the drive shaft
    BE2017 / 5639 can move within the respective recess to a limited extent without the respective flat cover element having to move as well. This reduces wear, and overheating of the cover elements is avoided.
    According to an advantageous development of the invention, the respective flat cover element is guided on the respective side wall via guide elements of the respective side wall. The guide elements are preferably positioned on an edge of the respective flat cover element, the guide elements defining a gap with the respective side wall, into which the flat cover element projects with its edge, partially covering the edge, a width of the gap being greater than a thickness of the flat surface Cover element is in the area of its edge. This allows a particularly advantageous, simple guidance of the flat cover elements in the area of the respective side wall without the risk that the cover elements block in the area of the guide elements.
    Preferred developments of the invention result from the subclaims and the description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted to this. It shows:

    Fig. 3 shows a side wall of the feed mechanism in a solo representation.
    The invention relates to a feed mechanism for an agricultural machine, in particular for a forage harvester.
    A feed mechanism 10 for an agricultural machine has a feed housing 12 with opposite side walls 11, as well as feed rollers 13, 14, 15, 16 forming pairs of feed rollers 17, 18.
    1 to 3 each show views of a feed mechanism 10 according to the invention in a viewing direction from the outside of a side wall 11 of the feed housing 12 of the feed mechanism 10.
    1 to 3, feed rollers 13, 14, 15 and 16 are shown, which form two feed roller pairs 17, 18 in the exemplary embodiment shown.
    The feed rollers 13, 14 thus form a first feed roller pair 17, viewed in the crop flow direction F of a crop, and the feed rollers 15, 16 form a rear feed roller pair 18, viewed in the crop flow direction F.
    The feed rollers 13, 14, 15 and 16 are preferably rotatably supported via their axes on the side walls 11 of the feed housing 12, the position of the axes of first, upper feed rollers 14, 16 of the pairs of feed rollers 17, 18 being changeable. The position of axes of the second, lower feed rollers 13, 15 of the pairs of feed rollers 17, 18, however, is preferably stationary. By displacing the first, upper feed rollers 14, 16 relative to the respective second, lower feed rollers 13, 15 of the respective feed roller pair 17, 18, a gap formed between the feed rollers 13, 14 and 15, 16 of the respective feed roller pair 17, 18 can pass through the crop in
    BE2017 / 5639
    Seen in the flow direction F must be conveyed through, adapted.
    1 to 3, a drive shaft 19 is also shown, via which the first, upper feed rollers 14, 16 of the feed roller pairs 17, 18 can be driven. The axes of the first feed rollers 14, 16 are therefore driven axes, that is to say shafts.
    In order to enable the displacement of the first, upper feed rollers 14, 16 relative to the respective second, lower feed rollers 13, 15 of the respective feed roller pair 17, 18, axes or shafts 20, 21 of the first feed rollers 14, 16 extend through the displacement thereof allowable recesses 22, 23 in the side walls 11. Furthermore, a drive shaft 19 for the first feed rollers 14, 16 extends through recesses 24 in the side walls 11 of the feed housing 12. These recesses 22, 23 and 24 in the side walls 11 of the feed housing 12 are in 4, which shows only one side wall 11 of the feed housing 12, is particularly clearly visible, the recesses 22, 23 and 24 being contoured or dimensioned such that the shafts or axes 20, 21 of the first feed rollers 14, 16 and thus the first feed rollers 14, 16 and the drive shaft 19 for the first feed rollers 14, 16 the desired relative movement to the second feed roller n can execute 13, 15 in order to be able to adjust the gap between the feed rollers of the feed roller pairs 17, 18.
    As can be seen in FIGS. 1 to 3, an axle guide 25, which is articulated on the side wall 11 of the intake housing 12 with a first end 26, engages on the rear first feed roller 16, seen in the material flow direction F, of the rear intake roller pair 18 viewed in the material flow direction F. is, namely such that this axle link 25 is pivoted with its first end 26 about a corresponding axis of rotation
    BE2017 / 5639 can be. At an opposite second end 27 of the axle guide 25, the axle link 25 is coupled to the first intake roller 16 of the rear intake roller pair 18 seen in the material flow direction F, namely in such a way that the axle or shaft 21 of this first intake roller 16 is rotatably mounted on the axle link 25. If the distance between the feed rollers 15, 16 of the rear feed roller pair 18 seen in the material flow direction F is to be changed, the axis 21 of the feed roller 16 can move within the recess 22, the axle guide 25, as shown in FIGS. 1 to 3, being removed directly can perform a pivoting movement about its first end 26 or the axis of rotation in the region of the first end 26.
    In the relative position of FIG. 1, a gap between the feed rollers 15, 16 of the rear feed roller pair 18 seen in the material flow direction F is minimal.
    In Fig. 3, this gap between the feed rollers 15, 16 of the feed roller pair 18 is maximum.
    In the state of FIG. 2, the first feed roller 16 of the rear feed roller pair 18 assumes a position such that the gap between the feed rollers 15, 16 of the rear feed roller pair 18 viewed in the direction of crop flow F is larger than in FIG. 1, but smaller than in FIG. 3rd
    As already stated, the first feed roller 14 of the front feed roller pair 17 seen in the material flow direction F and the drive shaft 19 for the first feed rollers 14, 16 can also be shifted accordingly, specifically within the recesses 23, 24 of the side walls 11, namely the axis 20 the first feed roller 14 of the feed roller pair 17 in the recess 23 and the drive shaft 19 in the recess 24 of the respective side wall 11 of the feed housing 12.
    BE2017 / 5639
    1 to 3 it can be seen that the axis 20 of the first feed roller 14 of the front feed roller pair 17 seen in the material flow direction F and the drive shaft 19 via a bearing rocker 28 with the second end 27 of the axle guide 25 or with the axis 21 or shaft the first feed roller 27 of the rear feed roller pair 18 as seen in the material flow direction F is coupled.
    In the exemplary embodiment shown, this bearing rocker 28 comprises three connection areas, namely a first connection area for the axle guide 25, a second connection area for the axis 20 of the first feed roller 14 of the front feed roller pair 17 as seen in the material flow direction F, and a third connection area for the drive shaft 19.
    It follows from the above details that in the preferred exemplary embodiment shown, the axle guide 25 is directly or directly coupled to the axle 21 of the first feed roller 16 of the rear feed roller pair 18 seen in the material flow direction F, whereas the axle link 25 is coupled to the axle 20 of the first feed roller 14 of the front feed roller pair 17 as seen in the material flow direction F, and indirectly or indirectly coupled to the drive shaft 19 via the bearing rocker 28.
    The axis 20 of the first feed roller 14 of the front feed roller pair 17 seen in the material flow direction F and the drive shaft 19 are rotatably mounted in the region of the respective connecting sections of the bearing rocker 28. Furthermore, there is a rotatable mounting between the bearing rocker 28 and the axle link 25 or the axis 21 of the first feed roller 16 of the rear feed roller pair 18 as seen in the direction of crop flow F.
    A flat cover element 29 is arranged in the region of at least one side wall 11 of the feed housing 12 of the feed mechanism 10.
    BE2017 / 5639
    This flat covering element 29 serves to partially cover at least some of the recesses in the respective side wall 11, in the exemplary embodiment shown to partially cover the recesses 23 and 24, but not to cover the recesses 22.
    Depending on the relative position of the first feed rollers 14, 16 relative to the second feed rollers 13, 15 of the feed roller pairs 17, 18, the respective cover element 29 covers the recess 23, 24 in the area of the respective side wall 11, with those partial areas of FIGS Recesses 23, 24, which are covered by the respective cover element 29 in the respective state of the feed mechanism 10, are highlighted with hatching. The sections or areas of the recesses 23, 24 which are hatched in FIGS. 1 and 3 and which are covered by the respective cover element 29 in the respective relative position of the first feed rollers 14, 16 to the second feed rollers 13, 15 are shown in FIG. 1 the reference numbers 23-1,24-1, in Fig. 2 with the reference numbers 23-2, 24-2 and in Fig. 3 with the reference numbers 23-3, 24-3.
    The respective flat cover element 29, which is positioned in the region of the respective side wall 11 and extends parallel to the respective side wall 11, also has recesses 30, 31 which are in each case covered with the recesses to be partially covered, i.e. in FIGS. 1 to 3 with the recesses 23, 24, interaction. The respective flat covering element 29 in FIGS. 1 to 3 has recesses 30, 31.
    The recess 30 of the respective cover element 29 interacts with the recess 23 of the respective side wall 11, so that through these cooperating or corresponding recesses 23, 30 the axis 20 or shaft of the first feed roller 14 of the front feed roller pair 17 seen in the material flow direction F extends.
    BE2017 / 5639
    The recess 31 of the respective cover element 29 interacts with the
    Recess 24 of the respective side wall 11 together so that the drive shaft 19 for the first feed rollers 14, 16 extends through these interacting or corresponding recesses 24, 31.
    The recess 30 of the cover element 29 accordingly corresponds to the recess 23 of the side wall 11 and the recess 31 of the cover element 29 corresponds to the recess 24 of the side wall 11.
    The recesses 30, 31 in the respective cover element 29 are each smaller than the recesses 23, 24 in the respective side wall 11, so that, depending on the relative position of the first feed rollers 14, 16 to the second feed rollers 13, 15, the cover element 29 in FIG Fig. 1 to 3 hatched sections 23-1, 24-1 or 23-2, 24-2 or 23-3, 24-3 covered. Such areas of the recesses 23, 24 of the respective side wall 11, which are aligned with the recesses 30, 31 of the respective cover element 29 depending on the relative position of the first feed rollers 14, 16 to the second feed rollers 13, 17, are released by the respective flat cover element 29.
    The respective flat cover element 29 is controlled by the relative movement of a shaft or axis 20 which extends through a recess 30 of the respective cover element 29, namely when the axis 20 guided through the respective recess 30 of the cover element 29 is at the boundary of the respective recess 30 comes to the plant and is moved in the appropriate direction. The recess 30 in the respective cover element 29 is dimensioned such that a movement of the shaft or axis 20 within the recess 30 of the respective cover element 29 is possible without the respective cover element 29 moving.
    BE2017 / 5639
    As a result, the respective cover element 29 is subject to a slight one
    Wear and a little warming.
    The movement of the cover element 29 could alternatively and / or additionally be controlled by the relative movement of the drive shaft 19 extending through the recess 31.
    The respective flat cover element 29 is guided in the region of the respective side wall 11 via guide elements 32, these guide elements 32 being positioned at the edge of the respective flat cover element 29 and covering the edge of the respective flat cover element 10 29 in sections depending on its current position.
    The guide elements 32 define this together with the respective one
    Side wall 11 has a gap into which the respective flat cover element projects with its edge, a width of this gap being greater than a thickness of the respective flat cover element 29 in the region 15 of its edge, so that the respective cover element 29 can move freely along the guides 32 .
