Abstract
A harvesting machine is provided with a separate improved rethresher for rethreshing tailings to thereby increase the overall efficiency of the machine. The rethresher comprises a rotor rotatably mounted within a cylindrical casing which cooperates with stationary threshing members on the inner curve wall of the casing to rethresh tailings supplied thereto. The casing is provided with internal spiral fins to effect movement of the rethresh tailings generally actually towards a transition opening in a common wall which is located at the inlet opening of the casing and serves as shield for preventing the tailings from being discharged prematurely from the casing. Further provided, is an impeller rotor mounted within a cylindrical casing adjacent the rethresher casing. The impeller rotor is co-axial with the rethresher rotor and is adapted to receive rethresh tailings from the rethresher rotor through the transition opening to discharge rethresh tailings substantially and gently through the impeller casing outlet.
