The metrics of which is located not above the inlet 22 (Fig. 6) of the overflow pipe 6. The IL-21 21 has a rivet wall 23 (Fig. 3) and a flange 24 (Fig. 3, 5). The end wall 23 is rigidly connected to the shaft 25 (Fig. 3) mounted in bearings 26 and 27 mounted on the bracket 28 of the pocket 12. The free end of the cylinder 21 is provided with a flange 29 (Fig. 5) fixed on the flange 24 and consisting of two half-rings 30 and 31 (Fig. 4).

The hollow perforated cylinder 21 is provided with a continuous perforated element 32 enveloping it (FIGS. 2, .. 3, 6, and 7), for tensioning which a roller 33 is provided fixed to the side walls 15 and 16 of the pocket 12. The continuous perforated element 32 rests on the deflection A roller 34 (FIGS. 2, 6, 7), mounted in such a way that the horizontal plane of its symmetry is not located below the horizontal plane of symmetry of the perforated cylinder 21.

The flange 29 of the cylinder 21 forms with flanging 20 of the shell 19 of the pocket 12 an annular gap 35 (FIG. 5), the width of which does not exceed the size of the perforation of the continuous element 32.

In the cavity of the perforated cylinder 21 there is placed a nozzle 36 fixed on the side wall 15 of the pocket 12 (Fig. Z-5), by means of which the circulation pump 11 communicates with the chamber 5 of the final wash. To drive a hollow perforated cylinder 21, an asterisk 37 is mounted on the shaft of the drum 8 (Fig. 3), and an asterisk 38 is attached to the shaft 25. These asterisks are connected by a chain 39.

The axis 40 (Fig. 2) of the tension roller 33 is provided with brackets 41 and 42 (Fig. 2, 3), on which is fixed

a scraper 43, made of elastic material and installed with the possibility of adjusting the angle of inclination relative to the continuous perforated element 32 and the inter-aura between them.

The device for washing of the root-and-vegetable crops works as follows.

Kamkelovushka 9 and chamber 5 of the final washing are filled with water to the level of the inlet 22 of the overflow pipe 6. Raw materials, such as potatoes, are fed into the drum 7 of the prewash chamber 4 where, during the washing process, along with the removal of soil, sand and small stones there is a partial removal of light impurities (straw, tops, leaves). Next, the raw material enters the stone trap 9, where, under the action of the upward flow of washing water generated by the circulation pump 11, at the same time as the potatoes are washed, the stones are separated and removed from the device by an inclined conveyor 10. From the stone trap 9, the potatoes are transported 5 of the final wash, where it is washed of residual contaminants, after which it is discharged from the device in tray 3.

The light impurities that are separated during the washing process by the directed flow of water created by the circulation pump 11 are moved into the cavity of the pocket 12 and pressed by this flow to the outer surface of the continuous perforated element 32, thereby ensuring reliable trapping of light impurities that float throughout the water in chamber 5 of the final wash.
