FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to metal latticed flooring covering manure channels in a cattle-breeding premises. Lattice covering of manure channel, which is made with possibility of repair, contains rectangular frame with parallel elements arranged relative to longitudinal angle elements with gaps between them. Horizontal flanges of two longitudinal support angles (1) are arranged on walls of the manure-cleaning channel. In vertical shelves of transverse short corners (2) holes are made, in which tubular elements are placed - rods with tubes (5) of elastic wear-resistant shock-absorbing material. At that, rods are installed with the possibility of replacement, free rotation in holes of short transverse angles, displacement by 5–10 mm in horizontal plane and fixed on one side with fixed washer, and on the other side - with a cotter pin.
EFFECT: simplified process of making grate, reduced metal consumption of device.
