RU177361U1 - Shredder root crop chopper - Google Patents

Abstract

The utility model is intended for grinding agricultural products and can be used for grinding root crops, pumpkins, succulent and roughage. This design contains a hollow cylinder with a loading funnel, a feeding screw, a chopping organ, an unloading window, overlapping deck. The claimed utility model eliminates the arching of large beets and restricting its movement to the chopping organ. The technical result is achieved due to the fact that the side walls of the chopper hopper have a hinge in the upper part of the hopper with hopper walls rigidly attached to the chopper body.

Description

The utility model relates to the field of processing agricultural products and can be used to grind pumpkins, coarse, succulent feed and root crops.

Known small-sized farm shredder-mixer of agricultural products, including a vertical shaft with knives fixed on it and a thrower with blades enclosed in a casing with contradictions, passing into the hopper, a loading tray in the form of sidewalls and a base, as well as an outlet pipe mass [1].

Known feed chopper-mixer, which includes a vertical cutting body located in the housing, made in the form of a screw thread with cutting edges along its periphery, and a counter member covering the cutting body. At the same time, a screw working element with a tape screw and the directions of winding and rotation opposite to the cutting body is used as a counter element [2].

However, the design solutions of known machines have low functionality and when grinding root crops, large losses of juice.

The claimed technical solution is aimed at use in small farms and farms with a small number of animals. The versatility of the claimed technical solution is achieved due to the simultaneous grinding of coarse, succulent feed and root crops.

The prototype of the proposed technical solution is a screw feed chopper [3].

This design contains a hollow cylinder with a loading hopper, a feeding screw, a grinding organ and an unloading window, overlapped deck.

However, in the process of grinding root crops when large beets get into the chopper hopper, arising occurs, i.e. restriction of their movement to the grinding organ, which leads to disruption of the process.

The purpose of the claimed utility model is to exclude arching and restricting the movement of fodder beets to the chopping organ.

The technical result is achieved due to the fact that the side walls 2 of the hopper 1 of the chopper 6 have a hinge 4 in the upper part of the hopper 1 with the walls of the hopper 3, rigidly attached to the housing 5 of the chopper 6. In this case, between the housing 5 and the side walls 2 of the hopper 1 there is a guaranteed a gap for the movement of the side walls 2 of the hopper 1 relative to the housing 5.

In the case of arching, the root crop pressures on the side wall 2 of the hopper 1, due to which the side wall 2 is deflected by a certain angle (the deviation is limited by the emphasis 7), thereby the root crop is released and under pressure of its own weight falls on the chopper auger. The pressure force of the root crop depends on the amount of compression of the spring 8.

The rotary root crop chopper works as follows:

The root crop, coming from the hopper 1, to the feeding screw 9, where it falls under the action of the sickle-shaped knives 10, when moving to the discharge window, the larger parts of the root crops on the periphery of the chopper body 5 are crushed with a knife and exit through the through holes 12 of deck 13. The degree of grinding is regulated by the deck 13 with corresponding through holes 12.

In FIG. 1 shows a frontal section of a rotary tuber auger grinder.
