FIELD: civil engineering. SUBSTANCE: baffle plates adjusting the thickness of filled material are installed symmetrically along side walls of hopper. Said plates are interconnected by their rotation axle secured on front end of hopper and another axle which is provided with a rod having a reciprocating drive. For changing the area of lower cutouts, their height is adjusted by means of baffle plates. Rod is set in motion by a hydraulic system and baffle plates start moving down in proportion to the distance covered. As the working member and hopper are raised out of the ground, the baffle plates come back to the initial position. EFFECT: improved design. 3 dwg
