APPARATUS FOR REMOVAL OF LIQUID AND SEMI-LIQUID MANURE Russian patent published in 2006 - IPC A01K1/01 

FIELD: agricultural engineering.

SUBSTANCE: apparatus has transportation members made in the form of flexible cylindrical screws and placed in longitudinal and transverse manure channels formed triangular in shape and closed from the top by grids, and drive adapted for transportation members and arranged at material discharge side of apparatus. Hollow cylinder mounted within flexible cylindrical screw in material discharge zone is equipped with conical bottom whose apex is oriented toward material flow direction. Spiral knives secured on external surface of cylinder comprise coils having coiling direction opposite to that of coiling of cylindrical screw. Leading part facing conical bottom has conical entrance part. Cylinder is designed for rotation toward transportation member at rotational velocity equal to that of transportation member.

EFFECT: increased efficiency in removal of liquid and semi-liquid manure containing large amount of elongated fiber inclusions, improved quality and reduced consumption of power for removal of manure.
