HELICAL ELEMENT ROTOR - AXIAL FLOW COMBINE

摘要

HELICAL ELEMENT ROTOR-AXIAL FLOW COMBINE A general purpose rasp bar carrying rotor constructtion for an axial flow-type harvester combine embodying a vaned impeller and a series of bars which cooperate with elements within the surrounding rotor casing for crop threshing and grain separation purposes in a novel and efficient manner. The rotor proper is generally of imperforate tubular cylindrical construction so that the crop material in its entirety is confined to the annulus which exists between the rotor and its casing. The threshing portion of the rotor having both helical and longitudinal extending rasp bars.
