The invention relates to the sorting of granular materials by specific gravity and can be used in the enrichment of minerals, agriculture, in the production of cereals and flour.

The goal is to improve the quality of separation of grain mixtures by adjusting the separator to the thickness of the layer to be separated.

Fig. 1 shows a grain cleaning machine, a longitudinal section, a longitudinal section; 2 is the lower part of the rotor with a separator in the form of radially arranged tubes; FIG. 3 shows the movement pattern of the light and heavy fractions during separation.

The machine includes a vertical cylindrical non-perforated rotor 4 with rippers 5 on its inner surface and scrapers 6, vertical shaft 7, rotating from and off from the pulley 2 and oscillating along and around the vertical axis from the vibration exciter 3. in the upper part of which is located the spreader 8 of the loading device. In the lower part of the rotor there is a separator, made in the form of radially arranged tubes 9, installed along the rotor height, in a staggered order and with the possibility of radial movements by means of, for example, an adjusting conical ring 10 installed coaxially to it and fixed on it discharging scrapers 1 1, supported and lowered by screws 12. There are unloading discharges in the lower part of the mashine; about 1 13 for heavy 3 and for light 14 fractions.

The machine works in a manner. Grain Blend with Spreader 8

The centrifugal force, the force of gravity and the oscillatory effects of the rotor 4 with spikes-loosened by the bodies 5 enters the inner surface of the rotor 4 by intensively overheating the seeds by the specific gravity and moving the mixture down. In the process of moving the grain, the mixture is self-sorted to heavy and easy

2 fractions. Approaching the separation pipes 9, the light fraction enters their necks (Fig. 3) and moves along the inner surface of the adjusting ring 10 with scrapers 11 to

2Q discharge tray 14 (figure 1). The installation of the tubes 9 at the boundary of the separated fractions is achieved by raising or lowering the screws 12 with the ring 10. When lowering the ring 10

25 it pushes the tubes 9 into the inside of the rotor 4 with its inner surface. The tubes 9 have bevels at the ends coming out of the rotor, equal to the slope of the inner surface of the ring 10, which is not necessary so that when it is lowered they slide along it. When lowering, the ring 10 presses on the tubes 9 and they move in the radial direction to the height required for installation at the interface of the layers of the separated fractions. If it is necessary to move the tubes 9 in the radial direction outward of the rotor 4, then the ring 10 is lifted up with screws 12. The tubes 9 are released from the backwater by the ring 10, and (C. the centrifugal force of the rotary axis 1 of the rotor 4 is withdrawn and outwards and abut the inner surface P) ring 10, lifting and lowering the ring 10, you can adjust the thickness of the removal of the light fraction. In order for the light fraction to pass through the tube 9, the Hg is stopped in it backed up by the ring 10, the lower part of the tube 9 has discharge windows in the lower part (Fig. 3). The installation of radially arranged tubes with the possibility of their radial alternations provides for setting the separator on the separation line. fractions, i.e. eat light fraction of any thickness. If the heavy fraction is not at all, then the tubes 9 can be completely inserted into the rotor body so that they do not protrude above the inner surface of the rotor D, then the whole grain mixture will be discharged by the tubes 9 If the heavy fraction is accumulated full layer, then the tubes move to its thickness. Then the heavy fraction, which bends the tube 9, moves downwards and is scraped off by the scrapers 6 into the tray 13 (Fig. 1), and is easily removed through the tubes 9 (Fig. 3). If the heavy fraction does not accumulate a complete elementary layer to fill the entire inner surface of the rotor 4, then the passage between the tubes 9 s turns, the flow of grains is slowed down and raised. As a consequence, near the tubes 9, the inner surface of the rotor 4 is filled with heavy particles and a layer is formed. This makes it possible for more tpiko to separate the hardly separable mixture, in contrast to the prototype. The tubes 9 are installed with distances that prevent the mixture grains from getting stuck between them. Installing the tubes 9 in a checkerboard pattern allows them to bend around the moving mixture and remove the light fraction around the entire perimeter of the rotor. With a large productive I and the number of rows of tubes I

There are more than two. This is necessary to completely remove the light fraction.
