The use of various sieve, air and trimeric separators does not give positive results when cleaning grain material from ergot due to the proximity of their properties and the properties of the culture to be purified [3, 4, 5].

Ergot horns, which are poisonous impurities in the grain material, have a lower density than that of rye and other cereal crops. Therefore, to isolate the horns of ergot from rye seeds, you can use solutions of sodium chloride or potassium salt [6].

The simplest way to isolate the ergot horns from rye seeds is a bath with an aqueous solution of salt with a sieve placed in it, the external dimensions of which correspond to the internal dimensions of the bath. When feeding rye grain, full-weighted seeds sink to the bottom of the bath, and the ergot horns appear on the surface of the solution, which are removed by a net, and then the sieve from which the solution will drain is taken from the bath with full-weighted seeds. In this case, the issue of mechanization of separation of ergot horns from grain material is topical.

For the mechanization of the separation of the horns of ergot from a grain material, a machine has been developed, which consists of a bath, transporters of rye seeds and ergot horns, a bunker with a feeder. Conveyors of rye seeds and ergot horns across the width of the bath are made in the form of belt screens with transverse strips installed at regular intervals along their length. The feeder wall is immersed in a salt solution and separates the cavity of the bath with a rye seed transporter from an ergot conveyor [7].

Another technical solution is that, in a well-known car, the transporters of rye seeds and ergot horns consist of scrappers installed at regular intervals along their length, which are fixed to closed traction chains, drive envelopes and driven sprockets. The bottom of the bath under the scrapers of the rye seed conveyor at its downstream end is made in the form of a sieve, under which the waste tank is located. A sieve is installed under the scrapers of the ergot conveyor horns, the output part of which is located above the level of the solution in the bath, and the lower end, immersed in the solution, is connected to the reflective plane [8].

The presented technical solutions ensure, due to their constructive execution, a reduction in the specific energy intensity of the technological process, a decrease in metal consumption and unit costs for the maintenance and repair of the machine, and an improvement in the quality of cleaning rye seeds.
