Abstract

This invention relates to devices for cleaning and separating grain materials to them. b. used in sec. x., the system of bread and other otras x. The aim of the invention is to improve the quality of the separation process by reducing the loss of grain from the waste. A loading bunker 1 is placed above the horizontal sieve drum (RB) 2, and an arcuate sieve (DR) 4 is installed on the springs 5 opposite to the bunker. more than half the circumference of the cylindrical surface of the RB 2, and the sizes of the perforations of the DR 4 are larger than the sizes of the perforations of the RB 2. On the outer side of the cylindrical surface of the RB 2 and on the internal surface of the DR 4, pins 3 and 13 are installed in a checkerboard pattern. Lena skatna board 8. The original cereal mixture from the hopper. 1 is fed to RB 2, part of the grain material is sifted through it and enters receiver 10. Another part of the grain layer is transferred to RB 2 and gets into DR 4. The grain material passed through DR 4 enters the receiver of fractions 12. Large grain-impurities are extracted with pins 3 and enter the receiver fractions of 11.3 Cp f-ly, 2 ill. And te

Claims (4)

Claim 1. A scalper including a horizontal sieve drum rotatably mounted, a drum rotation drive, a loading hopper and receivers of grain material and large straw impurities located above the drum, characterized in that, in order to improve the quality of the separation process by reducing grain losses from waste, the scalper is equipped with an arcuate spring-loaded sieve, placed with a gap from the outside going to the descent of the cylindrical surface of the drum, an additional receiver of the grain mater ala placed under the arcuate sieve, the length of arcuate sieve of more than half of the cylindrical surface of the drum circumference the sieve, perforations and the arcuate sieve size larger than the sieve drum perforations, the size of the gap between the sieve drum and the sieve arcuate sieve drum decreases in the direction of rotation. 2. The scalper according to Claim 1. The condition is that it is equipped with a sloping board installed inside the sieve drum with an inclination towards the grain material receiver. 3. The scalper according to Claim 1, with a tout and the fact that it is equipped with pins mounted in a checkerboard pattern on the outer side of the cylindrical surface of the drum and on the surface of the arcuate sieve facing the drum. ’4. The scalper according to Claim.
