Mählader mit einem erntegut-aufnahmekopf

Abstract

In a harvester / header combination according to the invention, the header is a crop pick-up header (2) coupled to a forage harvester (1). The header comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, a rotatable auger (20) provided with two oppositely wound helicoidal flights (26), and one or more windguard rolls (15). The auger is rotatable with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger (20). According to the invention, the header comprises at least one set of actuators (18,19) capable of actively raising the auger and the windguard roll(s) and the harvester / header combination comprises a control unit (46) configured to execute a sequence of steps for removing a foreign object from the header, after detection of the object and stoppage of the harvester's feed rolls (51). The removal sequence includes raising the auger while rotating the auger in the reverse direction, followed by lowering the auger while maintaining said reverse rotation.
