Description

(54) GRINDER-DESTRUCTOR

one

The invention relates to the field of agriculture, in particular to devices for the processing of feed.

A device for grinding products by the method of abrasion is known, in which the grinding body and organ are made in the form of six-sided tips II.

However, this device cannot be used for feed processing.

The device closest to the invention is the device, including the core. a pus inside which a screw and grinding bodies with cutting edges are placed on one shaft, made in the form of nozzles displaced one relative to the other and forming a screw channel with the body, as well as an intermediate sleeve placed against knives radically mounted on the casing p.

A disadvantage of this device is the gradual decrease in productivity and quality of processing in connection with the wear of the cutting edge of the auger.

The purpose of the invention is to intensify the grinding process.

This goal is achieved by the fact that the intermediate sleeve is made in the form of a truncated cone, the apex of which faces the material supply side, while the length of the blades decreases in the direction of material unloading, and the cutting edges of the grinding bodies

5 are formed by intersecting the arc with a straight line, the grinding bodies being made increasing towards the discharge of material.

The body of the working chamber is made

10 in the form of a solid cylinder with a system of grooves.

Such an embodiment of the shredder ensures the reliability of the feed processing process and an increase in the production of the device. In addition, the product undergoes large changes in structure, and therefore its feed value is increased. FIG. 1 shows the proposed device, a longitudinal section; FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - chopping, organ, axonometric.,.

25 Shredder-destructor includes a housing, 1 with a receiving chamber 2 and a working chamber 3. In the housing 1. The shaft 4 is placed, on which the single-way supply screw 5 is fixed, the intermediate sleeve 6 is made in

the form of a truncated cone and bordering on not less than two knives 7 fixed to the internal working chamber 3, and from the exit side of the product to chopping bodies 8 mounted on the shaft and the image of two offset one with respect to the other arcs, combined with in a straight line. Working Chamber 3 is made in the back of the Continuous cylinder, equipped with a system of grooves 9, and the outer side of the arcs constituting the grinding bodies 8 has a ribbed shape 10. The grinding bodies 8 are offset from each other at an angle of 5-45 ° in the direction of the turns of the shaft. screw channels, and from the inner surface of chamber 3 they create a gap that has a stepped

form. .

The shredder-destructor works as follows.,

The material, which continuously enters the receiving chamber 2, is caught by the screw of the screw 5 and is fed into the zone of the intermediate sleeve 6. While advancing along it, the product is compacted, pressed, the knives 7 are kept from turning and, having acquired translational motion, falls into the screw channels formed the camera body 3 and the grinding bodies 8, where it makes translational motion from the wide part of the channel into the narrow and vice versa.

The material layer, which adjoins to the camera body 3, is inhibited from rotation by parts of the body in the grooves / of which the product is stuffed, and the ribbed surface of the organs 8 turns into rotational motion. An intense abrasion occurs between the product layers under high pressure 1m, resulting in crushing and destruction mi in the product structure. As the gap between the grinding bodies 8 and the body of cameo 3 decreases, the intensity of the product’s destructive changes increases.

The design of the shredder-destructor allows to intensify the production process and to obtain a feed product with a high degree of animal digestibility, as well as to reduce energy consumption per unit of production.
