CUTTING MECHANISM FOR AN AGRICULTURAL HARVESTING MACHINE AND METHOD FOR OPERATING A CUTTING MECHANISM

摘要

The present application relates to a cutting device (1) for an agricultural harvesting machine (2), in particular a combine harvester, comprising a support frame (3), cutter bar (4), a feed roller (6) which can be driven in rotation, and a stripping means (7) assigned to the feed roller (6) ), the feed roller (6) being designed to convey cut plants (5) starting from side regions (9, 10) of the cutting unit (1) in the direction of a central region (11) of the cutting unit (1), the stripping means (7 ) extends at a distance (12) from the feed roller (6), so that during operation of the feed roller (6) plants (5) moving in its circumferential direction can be wiped off by means of the wiping means (7), the feed roller (6) by means of a movement device (13) relative to the support frame (3). In order to provide a cutting mechanism in which, despite a fixed arrangement of a respective stripping means on the support frame, movement of the feeder gswalze is possible relative to the support frame, without thereby increasing the inclination of the feed roller for wrapping with cut plants, the invention proposes that the feed roller (6) by means of the movement device (13) is movable on a curved path (14) that the Distance (12) of the stripping means (7) from the feed roller (6) remains at least essentially unchanged in the course of the movement.
