Grain-straw separator for combine harvester

摘要

The threshing implement of the combine harvester is arranged so that the support rings (19) which carry the threshing teeth (20) can be mounted on the separator rotor (10). The rotor body has positioning ribs (18). The support rings have grooves which are slipped on the rotor body and prevented from rotating by the rotor ribs. The positioning ribs can comprise teeth (21) with spaces between them (22) into which a part of the support ring is engaged which are engaged on the rotor body
