FIELD: agricultural engineering.
SUBSTANCE: grain combine has longitudinally arranged housing incorporating separating rotor. Rotor casing has harvested mass charging zone positioned above shaft of separating rotor, separation zone equipped with sieving means, and discharge zone positioned at discharge end of rotor casing. Separating rotor has screw blades located in charging zone. Rotating member with transverse axis of rotation is positioned above separating rotor for feeding of harvested mass into rotor casing through feeding opening, which is surrounded with metal sheet extending through width of feeder casing. Metal sheet at least partly conforms in its shape to circumferential configuration of rotating member. Feeding opening is made wider in its lower part than in its upper part.
EFFECT: increased efficiency in harvesting of various cereal crops owing to feeding of harvested mass from feeder casing into rotor casing from position above shaft of separating rotor.
