FIELD: agriculture. SUBSTANCE: device comprises tubular piston 3 with pressure return valve 6 installed in it at the end directed to manure receiver 1. Suction return valve 5 is mounted above pressure valve in casing 2. Piston is installed in casing with a provision for reciprocating motion. Manure is delivered to piston and solid inclusions of litter are crushed by feeder disposed between manure receiver and piston. Said feeder has the form of plates 7 secured radially on shaft 8 which is coaxially installed in casing. Feeder is installed at an angle to the plane of rotation. Said angle is equal to 45 deg and is directed against direction of rotation of plates 7. Plates 7 have cutting edges interacting with counteredges 10 secured to internal surface of casing. Manure mass is transported into branch pipe 17 through alternately opening valves 5 and 6 during reciprocating motion of piston. EFFECT: improved design. 3 dwg
