  • Patent number: 10143131
    Abstract: A system for discharging residue from an agricultural combine to a ground surface. The system including a spreader operatively connected to a rear end of the agricultural combine. The spreader having one or more impellers each having an axis of rotation and a housing. The impellers are operatively connected to the housing for rotating therein. The housing has an inlet for receiving a flow of residue, an outlet configured about a lateral side of the housing for discharging the flow of residue, and one or more residue flow distributors each pivotably movable in a direction generally parallel with the axis of rotation. Each flow distributor is configured to guide the discharged flow of residue sidewardly away from the spreader to the ground surface. The rotation of the one or more impellers discharge a flow of residue received through the inlet out through the outlet.

  • Publication number: 20180235151
    Abstract: 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.
