Description

Beet harvester Technical Field The invention relates to a beet harvester, in particular for sugar beet, having a frame, a cleaning device which is arranged at the frame and has at least one star screen which can be rotated about a star screen axis, a conveying device, and a silo for temporarily storing the dredged beet. In operation, the conveyor device conveys the sugar beets excavated by the excavator group to the cleaning device and/or from the cleaning device into the storage bin. Background The performance of such machines needs to be constantly improved, which is already approaching a limit in terms of cleaning performance, in particular, for the functional units described above. Disclosure of Invention The object of the present invention is to improve the cleaning performance of such devices. This object is achieved by the subject matter according to claim 1. Advantageous embodiments of the invention emerge from the dependent claims and the following description. The beet harvester according to the invention (also called a beet digger unit) is characterized in that the star screen and/or the star screen frame are movably supported at the frame in a transverse direction transverse to the longitudinal centre axis of the beet harvester. The star screen is movably arranged such that the position of the star screen axis can be changed in the transverse direction, i.e. a movement in the transverse direction does not mean here a rotation of the star screen in operation. In the present application, reference is made to movement and/or movability of one or more star screens in the transverse direction, which in particular refers to movement and/or movability of one or more star screen frames arranged in the transverse direction. The at least one star-shaped screen and/or the star-shaped screen frame can be moved, in particular together, by the movement of the suspension, i.e. the suspension mechanism with one or more suspension points, or by the movement of the other holding part relative to the frame. The movement in the transverse direction here means a movement of the respective star-shaped screen, the star-shaped screen frame and/or its suspension or holding part in a plan view transversely to the longitudinal central axis of the star-shaped screen, and with reference to the longitudinal central axis, this movement is independent of the height of the star-shaped screen and/or the star-shaped screen frame above the ground on which the beet harvester rests, or at least approximately independent of this. Within the scope of the application, movement in the transverse direction may optionally: For movement, movability and/or displaceability only in the transverse direction, i.e. the horizontal transverse direction, or alternatively For a movement, a movability and/or a displaceability of parts, in particular of the scale, in the transverse direction, preferably of the scale, throughout its movement. In the present application, the transverse direction refers in particular to a horizontal transverse direction. The direction of the transverse direction is on the one hand transverse to the vertical direction and on the other hand Transverse to the direction of travel and/or to the longitudinal central axis of the beet harvester, or At least transversely to the longitudinal central axis of the machine frame in the region of the cleaning device. The movements and/or displacements in the transverse direction referred to in the present application are preferably movements and/or displacements under which the orientation, in particular the inclination, of the respective star-shaped screen and/or the star-shaped screen frame is substantially maintained, ideally unchanged. To this end, whether or not its orientation or tilt is changed by other movements and/or measures, for example, provision may be made for: Multi-joint support, for example in the form of a parallelogram guide; a plurality of, for example two, parallelogram links, which are pivotally supported on the struts of the machine frame and/or One or more adjusting mechanisms, for example in the form of hydraulic cylinders, That is, one or more star-shaped frames may optionally be provided, in particular a plurality of star-shaped frames being provided together. By means of the expansion of the installation space, which is associated in particular with the excavation operation, the throughput and the cleaning effect can be significantly increased in an improved, gentle transport. At least one star screen may swing outward in the digging position to increase the cleaning path and throughput. In addition, one or more larger star screens may be used that require more structural space in operation. By means of the embodiment according to the invention, the potential of a larger star screen can be used, for which purpose the star screen is optimally laterally displaced during operation. Accordingly, both the cleaning path and the cleaning area are increased. Furthe
