FIELD: agriculture.
SUBSTANCE: rotor (1) of the threshing and separating device of a combine harvester for harvesting hard-to-thresh crops contains a hollow cylinder with spiral blade (2) in lead-in zone (A), corrugated whips located in the front and rear parts of threshing zone (B). The corrugated whips of the front and rear parts of threshing zone (B) are staggered relative to each other and are made of one section. On the outer surface of the rotor housing in the separating part (V) there are lining brackets mounted on the brackets. The reefs of the whips in the rear part of threshing zone (B) are made in the opposite direction with respect to the reefs of the front part of threshing zone (B).
EFFECT: increased productivity of the combine harvester, increased threshing of grain from the ear when harvesting hard-to-thresh crops, reduced grain losses, as well as increased rotor service life.
