摘要

The concave has two threshing drums with rotors that are driven around a perpendicular axis. The beater includes stators with cylindrical covers that are associated with the drums. The covers surround the periphery of the beater, in which between the drums a space is provided for extracting the grains during the inflow of the straw. An angle between the drums is scalable between 90 and 180 degrees.
