Abstract

The invention relates to agriculture, in particular to shredders used in livestock farms. The purpose of the invention is to improve the quality and reduce the energy consumption of grinding with increased operational reliability. The chopper of green stalked food consists of a vertically mounted chamber 1 with cutting elements 2. Coaxially inside the chamber 1 there is a shaft 3 on which knives 4 are installed in the upper wheel and - knives 10. The knives 10 are hinged on the supporting elements 7 and lie between the support-distributing disks 5 with the possibility of free rotation around the axes 9. In each second element 7 the knives 10 are installed in the lower parts of the chamber 1. The axes 6 are placed eccentrically to the axis 9. The mass loaded into the chamber 1 is partially crushed, distributed through the chamber 1 and enters the cutting zone. At the same time, due to the different number of knives 4 and 10 according to the height of the shaft 3, rough, and then fine grinding of the whole mass occurs first. As a result, high quality and low energy intensity of the process are ensured. 2 Il. About with About Os About

The invention relates to agriculture, in particular to shredders used in livestock farms.

The purpose of the invention is to improve the quality and reduce the energy intensity of grinding with increasing operational reliability,

Figure 1 shows the chopper green stalked feed, side view; figure 2 is the same, top view.

The shredder consists of a vertically mounted chamber 1 with cutting elements 2 on its surface. Inside the chamber 1, the shaft 3 is coaxially mounted, equipped with knives 4 and rigidly mounted support-distributing disks 5 with 6 rotatable supporting elements 7 mounted between them on the axes x, which have horizontal grooves 8 with 9 blades mounted on the axes 10. In each second bearing element 7, the knives 10 are mounted in the lower part of the chamber 1. The axes 6 are placed eccentrically to the axis 9 of the fastening of the knives 10.

Grinder green stalked feed works as follows.

The green mass loaded into chamber 1 is partially crushed and distributed over the working volume of chamber 1 by knives 4 and support-distributing disks 5. Under the action of gravitational forces, the distributed mass enters the cutting zone to knives 10. At the same time, bearing elements 7 with different number of knives 10 alternate . In the upper russes of the knives 10, coarse grinding and further distribution of green mass over the volume of chamber 1 takes place.

The coarsely chopped and well dispersed mass enters the lower zone of intensive chopping of the knives 10, in which particles of a given zootechnical size are formed.

Thus, in the working chamber 1, the partial grinding and distribution of stalked feed, their rough grinding and distribution over the chamber volume, fine grinding of green stalked feed to a given size, which allows to evenly distribute the load on the shaft 3, reduce the energy intensity of the process are combined and performed. grinding and get with the minimum energy consumption the required particle size of the particles, feed particles.
