Abstract
A self-propelled combine harvester includes a transfer zone with side panels and a meshing and feed drum which functions on the tangential flow principle. The feed drum feeds the harvested crop to the separating rotors, which function on the axial flow principle and are rotatably mounted in rotor housings. Side panels are operatively mounted on the rotor housing in the frontal pickup region thereof Guide rails are directed upwardly at an acute angle and become increasingly elevated in the direction of conveyance, for imparting an upward, axially directed pulse to the harvested crop whereby the increasing elevation amplifies this pulse without thereby blocking the pickup zone in a frontal region. Dividing wedge for dividing the harvested crop into two paths, wherein the harvested crop glides over the dividing wedge towards the rotor housings and the long stemmed materials, such as stalks, are caught by the separating rotors and drawn into the corresponding rotor housing via the dividing wedge.
