    Feeder housing and harvester equipped therewith
    description
    The invention relates to a feeder housing for a harvester and equipped with such a feeder housing harvester.
    From DE 100 21 663 A1 a self-propelled forage harvester is known as a harvesting machine, which has a feeder housing, in which three pairs of feed rollers are arranged in succession in a crop conveying direction. Each pair of feed rollers is formed by a lower feed roller and a parallel to the lower feed roller and arranged above this upper feed roller, wherein each of the feed rollers is held on a transverse to the Erntegutförderrichtung axis element, so that it is rotatable about its respective central longitudinal axis. The harvesting machine also has a Erntegutförderrichtung the feed housing downstream Erntegutverarbeitungstrommel in the form of a chopper drum, which is arranged parallel to the feed rollers mounted so that it is rotatable about its central longitudinal axis.
    According to DE 100 21 663 A1, the axle elements of the upper feed rollers are mounted on two axle arms or rockers arranged at their opposite longitudinal ends via respective axle bearing points, the respective directionally identical longitudinal ends of these axle elements being connected to one another via the respectively assigned axle link. Each wishbone is connected at a respective junction with a respective connecting link which is pivotally mounted on a respective pivot bearing position on a wall of the feeder housing, so that by pivoting the two connecting links on the wall, a vertical distance of the upper
    Feed rollers of the lower feed rollers to adapt to different Erntegutstrangdicken is variable. The junction of respective wishbone and connecting link is located in a region of the axle guide, which extends from the Achslagerstelle a Erntegutförderrichtung last upper feed roller in the direction of the respective pivot bearing point. In this solution from the prior art, a pivot radius of the respective upper feed rollers decreases in the direction of the pivot bearing point down, so that the Erntegutförderrichtung last upper feed roller has the smallest pivot radius when changing the height distance to the last lower feed roller.
    Since the chopping drum formed in diameter larger than the feed rollers adjoins directly to the last pair of feed rollers in Erntegutförderrichtung, however, a small pivot radius of the last upper feed roller may be unfavorable in terms of maintaining a constant smallest possible distance of the last feed roller pair to the cutterhead. Since the feed roller pairs are to realize a pre-pressing of a feed through the housing crop line to improve the cutting conditions for the cutterhead, the maintenance of a constant smallest possible distance of the last pair of feed rollers to the cutter is important to avoid a before the chopper drum Aufauffächern the Erntegutstrangs. If the swivel radius of the last upper feed roller is smaller than the radius of the chopper drum, however, a constancy of the distance can not be guaranteed, which can come especially at thick Erntegutsträngen for increased distance and thus for refilling this. This in turn can affect the quality of cut on the cutterhead and thus the processing quality of the crop.
    The invention is based on the object, a feed housing for a harvester and equipped with such a feeder housing
    To provide harvester, which ensures a constant processing quality even with different Erntegutstrangdicken. This is achieved with a feed housing according to claim 1 or a harvesting machine according to claim 9. Further developments of the invention are defined in the respective dependent claims.
    The invention provides a feeder housing for a harvester, wherein the feeder housing comprises at least two pairs of feed rollers arranged one behind the other in a crop conveying direction, each pair of feed rollers being formed by a lower feed roller and a lower feed roller parallel to the lower feed roller and each upper feed roller the draw-in rollers are held on an axis element extending transversely to the crop conveying direction, so that it is rotatable about its respective central longitudinal axis. The axle elements of the upper feed rollers are mounted on two axle arms arranged at their opposite longitudinal ends via respective axle bearing points, the respective directionally identical longitudinal ends of these axle elements being connected to one another via the respectively assigned axle guide. Each wishbone is connected at a respective connection point with a respective associated connecting link, which is pivotally mounted on a wall of the feeder housing via a respective pivot bearing point, so that by the wall pivoting the two connecting link a height distance of the upper feed rollers of the lower feed rollers for adaptation different Erntegutstrangdicken is changeable.
    The feed housing according to the invention is characterized in that the junction of the respective wishbone and connecting link between the Achslagerstelle a Erntegutförderrichtung last upper feed roller and the Achslagerstelle a Erntegutförderrichtung first upper feed roller and the joints are each designed as a pivot bearing, so that the wishbone to one parallel to the respective one
    Central longitudinal axes of the upper feed rollers extending pivot axis are pivotable on the connecting links.
    Preferably, the axis elements of the upper feed rollers, in particular the respective longitudinal ends or adjacent portions of the axis elements of the upper feed rollers, guided in respective guides on the wall of the feeder housing, so that the axis elements of the upper
    Feed rollers at to change the height distance of the upper
    Feed rollers from the lower feed rollers Pivoting the two connecting links each follow a predetermined height adjustment path.
    By forming the joints as a pivot bearing and arranging the joints between the Achslagerstelle the last upper feed roller and the Achslagerstelle the first upper feed roller can be in as described leadership of the axis elements in e.g. Slits in sidewalls of the wall of the feeder housing the swivel radius for the in
    Erntegutförderrichtung last upper feed roller and for in
    Erntegutförderrichtung first upper feed roller to be adapted to a desired swing radius. In particular, the pivoting radius of the last upper feed roller in Erntegutförderrichtung better to the radius or outer circumference of a Erntegutförderrichtung the last
    Adjust feed roller pair downstream crop processing drum, thereby making it possible to ensure a constant smallest possible distance of the last upper feed roller for Erntegutverarbeitungstrommel (for example, chopper drum) at a height adjustment or pivoting of the upper feed rollers. Thus, a constant good quality of workmanship can be ensured even with different Erntegutstrangdicken this.
    In addition, can be flexibly adjusted by the inventive design and arrangement of joints an angle of the wishbone according to the height adjustment, whereby the height distance of the upper feed rollers and thus the pre-pressing a Erntegutstrangs are more flexible adjustable.
    Overall, with the feed housing according to the invention an optimized pre-pressing effect on a conveyed by the feed housing Erntegutmatte, which is particularly at higher heights of
    Crop strands beneficial effects.
    In addition, by the inventive design and arrangement of the joints in the intake operation or harvesting a commuting the
    Achslenker the upper feed rollers are allowed, whereby their smoothness is increased and thus the operating characteristics of the feed housing are improved.
    According to one embodiment of the intake housing according to the invention, the junction of the respective axle guide and connecting link is arranged so that a straight line from the junction to the Achslagerstelle in Erntegutförderrichtung last upper feed roller is shorter than a straight line from this junction to the Achslagerstelle the in Erntegutförderrichtung first upper feed roller.
    Thus, a pivoting of the wishbone about the pivot bearing at the junctions to the connecting links with respect to the height distance to the lower feed rollers at the Erntegutförderrichtung last upper feed roller affects less than at Erntegutförderrichtung first upper feed roller, whereby the pre-pressing in the most important area shortly before a crop processing downstream of the crop housing can be kept even better constant.
    According to a further embodiment of the feeder housing according to the invention, the junction of respective wishbone and connecting link is arranged so that the straight line from the junction to the Achslagerstelle the Erntegutförderrichtung last upper feed roller is shorter than a straight line from this junction to the pivot bearing point of respective connecting link.
    Due to the configuration of the junction of respective wishbone and connecting link as a pivot bearing, the straight line from the junction to the Achslagerstelle in Erntegutförderrichtung last upper feed roller is a second pivot lever whose pivot radius is approximately opposite or approximately mirror image of the pivot radius of the straight Distance from the junction to the pivot bearing point of the connecting link formed first pivot lever is. In interaction of both pivotal movements of the first and second pivot lever thus the resulting pivot radius is increased by a feed housing downstream Erntegutverarbeitungstrommel. Characterized in that the first pivot lever is shorter than the second pivot lever and thus has a smaller pivot radius, causes a certain Verschwenkausmaß the second pivot lever a greater change in distance in Erntegutförderrichtung last upper feed roller of the crop processing drum than the same Verschwenkausmaß the first pivot lever an opposite change in the distance last upper feed roller caused by the crop processing drum. Thus, at relatively low pivoting amount of the steering knuckle, the resulting pivot radius of the last upper feed roller can be adapted to the Erntegutverarbeitungstrommel suitable.
    According to yet another embodiment of the feeder housing according to the invention, the provided on the wall of the feeder housing pivot bearing points of the respective connecting links are arranged so that they are at minimum height distance of the upper feed rollers of the lower feed rollers above a plane passing through all axis elements of the upper feed rollers level.
    As a rule, a rotation axis or central longitudinal axis of the
    Erntegutverarbeitungstrommel is arranged approximately at the level of extending through all the axis elements of the upper feed rollers level, can by this arrangement of the pivot bearing points, with respect to the pivot radius of the connecting link a vertex or greatest distance of the connection points thus above the axis of rotation of the Erntegutverarbeitungstrommel, the last upper Feed roller with height adjustment even better follow the outer circumference of crop processing drum. In other words, for the last upper feed roller ensures that when pivoting the
    Connecting link up an increase in the distance of the feed roller and the pivoting of the connecting link down a distance reduction of the feed roller corresponding to the contour of the Erntegutverarbeitungstrommel takes place.
    According to yet another embodiment of the feed housing according to the invention, the connecting links are each formed so that they extend arcuately in a respective longitudinal direction thereof. In other words, the connecting links are preferably each formed as a lengthwise curved arcuate lever.
    By this arcuate curvature of the connecting link a mounting access is provided in the inner radius of curvature.
    According to one embodiment of the feed housing according to the invention, three feed roller pairs are arranged one behind the other in the crop conveying direction.
    The arrangement of three pairs of feed rollers on the one hand improves the pre-pressing of a crop strand conveyed by the intake housing and on the other hand provides a longer recognition path for detecting foreign bodies (such as metal), especially at ever higher feed speeds, which should not reach the crop processing drum. Thus, the processing quality and reliability of the feed housing are increased.
    According to another embodiment of the invention
    Feeder housing are the junctions of wishbones and connecting links at the respective Achslagerstellen a middle feed roller of the upper feed rollers. Preferably, the two connecting links are articulated directly to the respective longitudinal ends of the axle member of the middle upper feed roller and are thus connected via this axle element with their respective associated axle link.
    By means of this embodiment of the invention, the respective longitudinal ends of the axle element of the middle upper draw-in roller can be advantageously integrated into the connection points designed as pivot bearings, thus saving components such as additional pivot axes for the pivot bearing. In addition, the connecting links are cross-connected to one another via the axle element of the middle upper draw-in roller or via this itself at their ends and thereby stabilized against each other, whereby the height adjustment in the transverse direction is made uniform and tilting is avoided.
    The invention also provides a harvesting machine with a feeder housing according to one, several or all of the previously described embodiments of the invention in every conceivable combination, wherein the harvesting machine has a crop processing drum arranged downstream of the feeder housing in the crop conveying direction FR arranged parallel to the feed rollers, that it is rotatable about its central longitudinal axis, and wherein the pivot bearing points of the respective connecting links are arranged so that they are located above the central longitudinal axis or the axis of rotation of the crop processing drum - viewed with minimally deflected upper rollers.
    By this arrangement, the pivot bearing points, in terms of the pivot radius of the connecting link a vertex or greatest distance of the connection points thus above the axis of rotation or the central longitudinal axis of the Erntegutverarbeitungstrommel, the last upper feed roller can still better follow the height adjustment of the outer circumference of Erntegutverarbeitungstrommel. In other words, it is ensured for the last upper feed roller that when pivoting the connecting link up an increase in the distance of the feed roller and the pivoting of the connecting link down a distance reduction of the feed roller takes place according to the contour of the Erntegutverarbeitungstrommel.
    Moreover, since the harvesting machine according to the invention has the feed housing according to the invention, all the advantages and effects described above with respect to the feed housing according to the invention also apply to the harvesting machine according to the invention and therefore need not be mentioned again.
