The invention relates to a device for cleaning grain on sieves and can be used to separate other bulk materials.

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

Figure 1 shows a grain cleaning machine, a General view, figure 2 is a top view.

The device includes a disk sieve 1, mounted for oscillatory motion and connected to an oscillation generator 2. Through a hole in the center of the sieve 1 passes a shaft 3 mounted for rotation in bearings 4 and 5, the shaft 3 is kinematically connected to the rotation drive. including a reducer 6, an engine 7 and gears 8 and 9. On the shaft 3, a loading nozzle 10, an abutment 11 and a receiver of the oversize fraction 12 with an unloading window 13 are rigidly mounted. Under the sieve, a receiver of the sub-sill fraction 14 is installed, and under the unloading the window 13 of the receiver 12 has an annular tray 15.

The sieve 1 is divided into sectors 16, made with spring-loaded pushers 17 and installed with the possibility of deviation from the plane of the sieve by interacting with the stop 11.

The receiver of the oversize fraction 12 (see Fig. 2) is displaced relative to the loading nozzle 10 in the direction of rotation of the shaft 3.

Grain cleaning machine operates as follows,

When the drive is turned on, the sieve 1 under the action of the oscillation generator 2 oscillates, and the shaft 3, together with the loading nozzle 10, the stop 11 and the sieve fraction receiver 12, rotates in the bearings 4 and 5 under the action of the torque transmitted from the engine 7 through the gearbox 6 and gears 8 and 9.

The material to be separated enters the loading nozzle 10, from where it is poured onto the sieve 1, where it is divided into fractions under the influence of vibrations. Chalk

the fraction passes through the openings in the sieve and is collected in the receiver of the under-sieve fraction 14. The sieve fraction remains on the sieve. In contact with the stop 11 on the shaft 3 with the L-shaped pusher 17 on

sector 16, the latter rotates to a vertical position, while the receiver of the oversize fraction 12 is located under the rotated sector 16. The oversize fraction along the receiver 12 is poured through the discharge window 13 into the annular tray 15. After this, the sector 16 is returned to the horizontal position under the action of springs and is poured onto it a new portion of material.

The use of the inventive device makes it possible to increase the productivity of the process by 15 ... 20% and increase the quality of cleaning by 3 ... 5%.
