FIELD: agricultural engineering. SUBSTANCE: apparatus has hydraulic system, horizontal screw arranged in hopper case and equipped with adjustable gates, and inclined screw with pivot joint. Apparatus is further provided with hydraulic drive having pressure and drain lines and with distributor connected to combine hydraulic system. Distributor has two actuating hydraulic engines connected in series. First hydraulic engine of larger volume is connected to horizontal screw. Second hydraulic engine of smaller volume is connected to inclined screw. Pressure cavities of both hydraulic engines are communicated with one another through adjustable throttle. Back valves are arranged in pressure cavities of hydraulic drive control distributor of discharge apparatus. Such construction allows inclined screw to be fixed in different positions. EFFECT: simplified construction and increased efficiency. 3 cl, 2 dwg
