Abstract

The utility model relates to the field of agriculture, in particular to grain separators. The technical result is achieved in that the cone separator of crushed grain, including a loading nozzle, a gear motor, a sieve in the form of a truncated cone, placed one in the other, brushes, storage tanks, characterized in that the brushes are made with the possibility of reciprocating movement along the generatrix of the conical sieve. In one pass, the crushed product is divided into 4 fractions: fine, medium, coarse grinding and grinding, requiring additional grinding. 1 ill.

Description

The utility model relates to agricultural engineering, in particular to sieve separators, and can be used to separate grain material into fractions.

A device for separating grain material, including a sieve with a drive and a hopper. It is additionally equipped with brushes and a second sieve, while the sieves are made in the form of a truncated cone and the second sieve is placed in the first, with the larger base of the second sieve combined with the smaller base of the first sieve, the drive made in the form of a gear motor with a frequency converter, and the brushes are fixed in a vertical the plane from the outer surfaces of the sieves and made with the possibility of contact with the latter (description of patent RU No. 111965, IPC, published on 10.01.12).

A disadvantage of the known device is low productivity and low reliability.

The objective of the utility model is to increase the performance of the separator.

The technical result is an increase in productivity and reliability.

The technical result is achieved by the fact that the cone separator of crushed grain, including a loading nozzle, a gear motor, a sieve in the form of a truncated cone, one of which is placed in the first, brushes, storage tanks, brushes are made with the possibility of reciprocating movement along the generatrix of the cone sieves.

The drawing schematically shows a conical separator of crushed grain.

Cone separator of crushed grain includes loading pipe 1, sieve 2 with a mesh diameter of 2.2 mm, sieve 3 with a mesh diameter of 1 mm, sieve 4 with a mesh diameter of 1.7 mm, a gear motor with a frequency converter 5, storage tanks 6, 7 , 8, 9, brushes 10, frame 11, guides 12.

Cone separator crushed grain works as follows.

At the initial time, the gear motor 5 with a frequency converter is turned on, the shaft speed with conical sieves is regulated. The drive informs the brushes 10 of the reciprocating movement with an oscillation frequency of 20-25 min ^-1 along the generatrices of the conical sieves 2, 3, 4 along the guides 12. During the operation of the separator, the sieves 2, 3, 4 are penetrated by the tufts of hair of the brushes 10 and are cleaned of stuck particles grain, which in turn increases productivity by 1.5 times and gives high reliability of the device. The crushed material is fed into the loading pipe 1, from where it enters the working surface of the sieve 2, moving along which the material is separated, smaller than 2.2 mm, the recirculator larger than 2.2 mm goes immediately and enters the storage tank 6 (grinding, requiring additional grinding). Moving along the working surface of the sieve 3, grain up to 1 mm in size (fine grinding) is separated into tray 7, and grain 4 with a particle size of 1.5-1.7 mm (medium grinding) is sieved into tray 8, and the gathering is sieved from this sieve goes to tank 9 (coarse grinding). Thus, in one pass, the crushed material is divided into 4 fractions: fine, medium, coarse grinding and grinding, requiring additional grinding.
