The invention relates to agricultural machinery, in particular, devices for dividing the grain mixture into fractions in thickness and can be used in the milling and elevator industry for cleaning food grains, as well as coal, chemical, in the building materials industry, instrument engineering for sorting. technical stones in outer diameter.

A sorting device is known that includes a rotating horizontal drum made of stepped discs mounted on a shaft, between which there are flexible disks separated by support rings and fixed stops at the top of the drum so that annular slots are formed between the flexible and stepped disks Dj product

The disadvantage of this device is low productivity and increase in size with increasing disk diameters.

The closest to the proposed technical essence and the achieved effect is a cylindrical separator, including a rotating drum in the form of disk rings mounted on a shaft with the formation of gaps, a hopper, a collection of separation products jjZl.

However, the well-known separator is a “1G-one that is insufficiently produced, and also a low quality separation process.

The purpose of the invention is to increase productivity and improve the quality of separation.

This goal is achieved by the fact that a cylindrical separator, including a drum in the form of reinforced ones: on disk rings with gaps, loading bin 1, collection of separation products, is equipped with cutting plates J which are installed on the collection of separation products, and arc and placed in the spaces between the disk rings.

The figd depicts a cylindrical separator, a general view; on the collection of separation products; fig. 3 - technological scheme of operation 184312

you are a cylindrical separator; in Fig, 4 - section A-A in Fig.Z.

In the drawing, the following conventions are accepted:

J processed product;

. large impurities;

large grains; -, - medium grain; small grains;

10 p - small impurities, dust.

The cylindrical separator contains a drum 1 mounted on a shaft 2 having rolling bearings 3. In the inner part, drum 1 is inserted

15 disk rings 4, which are fixed against movements by the lock nuts 5 located on the bracket 6 of FIG. 1). The collections of products of section 8 (Figures 1 and 2) are attached to the housing 7 of the rolling bearings 3. On the collection of separation products 8, cut-off plates 9 are installed to separate the product grain thickness from the rotating disk rings 4.

5 The separator works as follows (fig. 3). .

Particles of the product entering the internal cavity of the disc rings 4. the drum 1 is uniformly distributed in thickness in the annular grooves formed by the inner surfaces of the disk rings 4 (section A-A in FIG. 3). Rotating, dirkovuyu ring. Cp 4 captures with itself the particles of the product, which, in contact with the working part of the cutting plates made in the shape of an arc, are less damaged. Moreover, the angular speed of rotation of the disk rings 4 is chosen so as to prevent the possibility of precipitation of particles of the product into the internal cavity.

When the cut-off plates 9 are reached, the product particles are separated from the inner surface of the disk rings 4

 plates 9 and enter the collection of separation products 8.

Cut-off plates 9, if they are made with a polyamide coating with the introduction of copper powder with

0 nickel are self-lubricating elements. After a certain accumulated time, they are changed.

The implementation of a separator equipped with cut-off plates that

5 installed on the collection of separation products, with the formation of the working parts of the cutting plates in the form of an arc, and placing them in the gaps will allow 3niSfSl between the disk rings and also improve the quality of separation of its production-paratsii.
