Conical rotor discharge housing with adjustable vanes

摘要

A threshing system for an agricultural harvester includes a rotor having a proximal end adapted to receive material from a feeding mechanism and a distal end. A discharge housing surrounds the distal end of the rotor. The discharge housing includes a side wall spaced radially apart from the rotor to define a discharge passage between the rotor and the discharge housing. At least one vane is pivotably mounted to the side wall of the discharge housing at a downward swept side of the rotor. The vane extends from the inner surface of the discharge housing. The position of the vane is adjustable to change a trajectory of material expelled from the discharge passage. The vane is positioned on a large diameter portion of the discharge housing in order to limit compression of the material as the material passes along the at least one vane.
