FIELD: agricultural engineering. ^ SUBSTANCE: invention refers to agricultural engineering and can be used in screen-air cleaners of combine harvesters. The rotary harvester-thresher includes a rotor rotating inside the skeleton frame, a cleaning unit, a suction-fan and grain collectors located under the rotor housing. The side of the combine harvester housing above the grain collector has at least one opening for waste discharge that is forwarded to the ground or into the cutter through the pipes. ^ EFFECT: higher cleaning efficiency and a low cost of the grain cleaning process. ^ 5 cl, 1 dwg |
