Abstract
The invention concerns a harvested crop processing unit with a rotor, a rotor housing enclosing the rotor, a cover element of the rotor housing, and a first group of helical guide rails that can be moved relative to the cover element between an operating position in which they are located underneath the cover element in engagement with harvested crop and a non-operating position in which they are located above the cover element. The invention proposes that a second group of helical guide rails be provided that can be moved alternately with the first group of helical guide rails relative to the cover element between an operating position in which they are located underneath the cover element in engagement with harvested crop and a non-operating position in which they are located above the cover element, and that are provided with an inclination that differs from the inclination of the guide rail of the first group.
