Abstract
A straw or chaff chopper attachment for a combine has at least one delivery funnel which can be fixed in place on the outlet hood of the combine, a cup-shaped rotor housing disposed under the delivery funnel, and an ejection chute connected with the rotor housing. The cup-shaped rotor housing is disposed underneath the delivery funnel and is capable of being pivoted back and forth around a vertical pivot axis (6) on a shaft (7). A chopping and ejection unit (8) disposed in the cup-shaped rotor housing (4), which rotates around the shaft (7), which extends coaxially with the vertical pivot axis (6) and chops the material and ejects it at the same time. A pair of the delivery funnels may be coupled for axial rotation about respective vertical pivot axes such that their respective ejection chutes move together. The chopper and ejection unit (8) may include a flat-table turning disk (11) rotatable around the vertical shaft (7), beaters (12) fixed on the turntable (11), flails (13) with cutting edges (13a) freely movable to oscillate, adjustably mounted counter-cutters (14) projecting into the rotor housing (4), and at least one cutter comb (15) to cooperatively act with the flails (13).
