FIELD: agricultural engineering, in particular, grain combines having separating rotor positioned lengthwise of and enclosed within casing.
SUBSTANCE: grain combine has rotor with feeding zone, separation zone and discharge zone, the latter being disposed at discharge end of rotor casing. Suction fan is designed for sucking of air flow through grid means provided in rotor casing and discharge of contaminants from combine. Drive means for driving of suction fan and separating rotor provides for regulation of relative rotational velocities of suction fan and related separating rotor.
EFFECT: increased separating capacity owing to increased efficiency of suction fan.
