FIELD: agricultural engineering.
SUBSTANCE: invention can be used in grain harvesting. Proposed grain harvesting machine includes power unit, wheel frame and trailer. Wheel frame carries stripping chamber, housing with suction port, receiver and fan. Stripping cylinder with working members is arranged in housing of stripping chamber. Fishback formed by chutes with beveled ends is arranged under stripping cylinder. Said chutes are installed with tilting and communicate with receiver. The latter is connected with inclined chamber provided with scraper conveyor. Fan with deflector is arranged over receiver higher than stripping cylinder. Inclined chamber and deflector communicate with trailer through pneumatic drive. Inclined chutes of fishback divide bulk grain into strips and entrap grains shattered at oscillation of stems.
EFFECT: reduced losses of grain.
