摘要
FIELD: excavating equipment. SUBSTANCE: device includes suspended drawing frame secured at obtuse angle to housing that frames a screw conveyor placed inside it. The housing is provided with sub-cutter bottom with mechanical transmission to transmit rotation from engine, placed on rear side of the housing, to the screw conveyor. Soil cut with lateral cutting blade sections enters through loading aperture to the screw conveyor and is fed upward to blade- type throwing unit placed over the screw conveyor. The throwing unit with rotary blades driven by the engine feeds the soil through throwing unit aperture to the side beyond pit edge. In so doing throwing unit case rests on screw conveyor housing through rotary circle and through mechanical transmission. The transmission shaft may be revolved from the engine that allows one to change direction of the soil being thrown. EFFECT: it allows to correct compactness of the soil even with forward motion of the base vehicle in the process of pit excavation; decreased size of the throwing unit; decreased power consumption. 4 dwg
