The invention relates to a technique for the classification of bulk materials by grain size, in particular, to the separation of grain mixtures in agriculture.

The purpose of the invention is to improve the accuracy of the separation of the material.

Figure 1 shows the device, a general view; figure 2 is a view of And figure 1; on fig.Z - type B PA figure 1.

The device contains a loading hopper 1, under which a device for preliminary sieving of material in the form of rods 2 and cattle boards 3 is installed. The distances between the rods increase from the loading end to the unloading one. The surface of the neighboring bars of different roughness. Under the rods 2, along their length, the pitched boards 3 are installed, which by means of the screw connection C have the ability to move relative to the rods 2 and make different angles with them. The rods 2 are placed on the NL olornchich stacks 5. Under the loading Punker 1 is installed vibrator ft, which leads to the oscillatory movement of the rods 2, At the discharge rods g, an additional collection / large fraction is installed. Under the pitched discs 3 on the shaft 8 is installed; rotating discs 9, which are annular between corals, slots, suitable trays 10 with receiving fingers 11 adjoin the unloading part of the disks 9. Under side trays 10 collectors 12 fractions are placed. Clearance ms --- d rod. MI increases towards Rraggpp disks 9.

Device guvo way.

The raw grain mixture from the hopper 1 goes onto the oscillating rods 2 and is pre-divided.

g on them in size. The largest particles enter the collection of a large fraction 7, and the rest of them, moving along the bars 2, sift onto pitched boards 3 and fall onto

JQ rotating disks 9, while small particles enter the stepped slots between the disks 9 faster than large ones. Thereafter, the fractionated product by the by-pass trays 10

15 enters collections of 12 fractions.

Changing the position of the pitched planks 3, as well as the amplitude and frequency of oscillation of the bars, allows you to find the optimal mode, sorting for

20 concrete mixture of grains.
