Description

FIG. one

The invention relates to agriculture, in particular to a shredder of feed used in livestock farms.

The purpose of the invention is to improve the quality of grinding and reduce energy intensity.

FIG. 1 shows a feed chopper; in fig. 2 is a section A-A in FIG. one.

The feed chopper consists of a working chamber 1 with cutting elements 2 on its inner surface. Inside the chamber 1, a shaft 3 is mounted with it, equipped with knives 4 radially mounted on it, interacting with cutting elements 2. Inside the chamber 1, in front of each block of cutting elements 2, a plate 5 is installed in the zone of action of the knives 4 adjacent to the working area of cutting elements 2. The front face 6 of the plate 5 is made at an acute angle to the direction of rotation of the shaft, and its length is determined by the expression

The mass entering the chamber 1 is green

by knives 4 is distributed over the volume of the chamber 30, its length # defined by expression 1 and under the action of centrifugal forces and air flow is thrown into the cutting zone of the cutting elements 2 and knives 4. When moving along the inner surface of the chamber 1, the green mass accumulates and compresses the inclined plane of the plates 5, turned against the direction of rotation of the shaft 3.,,

The compacted mass is fed by the blades 4 to the cutting elements, and the cutting is performed with less power. Reducing the gap prevents sticking of feed particles on the cutting elements 2 and the extreme edge of the blade of the knife 4.

As a result of the fact that the plates 5 are located in front of the cutting elements 2, and its height corresponds to the height of the cutting elements 2 installed in the chamber 1, the centrifugal forces are weakened and the speeds of the moving masses are broken, which makes it possible to reduce the soaring period of small green mass particles in the chamber 1 and thereby increasing the productivity of the shredder, without worsening the process of distribution of the incoming green mass over the volume of the chamber 1.
