Abstract

Usage: in agriculture for cleaning root crops, for example beets, of heavy impurities and can improve the reliability and quality of cleaning. SUMMARY OF THE INVENTION: The inner surface of the drum has a screw 8, 11 which feeds heavy impurities to the blade 12 and the folding tray 13, as well as the blade 9 for mixing the plant material. The blades 7 connecting the drums 5 to the shaft 6 activate the process and feed the raw materials to the discharge chute 11, which can be pulled out of the drum, providing the required cleaning quality and productivity. Small particles of heavy impurities passing through the perforation are fed with a screw 14 fixed to the outer surface of the drum and a scraper 15 overflow window 2, providing a constant discharge of sediment. Pure water is supplied to the unloaded root crops, rinsing them. The main water, if necessary, is discharged from the water through the drain window 3. 2 s, s.p., 4 HI. ё 00 yu s4; th vj

Description

The invention relates to devices for washing root crops, for example, beets, potatoes, carrots and separating heavy impurities, and can be used in agriculture, in the food industry, in trade, in warehouses and bases, as well as in other sectors of the national economy.

The purpose of the invention is to increase the efficiency of the workflow by increasing reliability and reducing raw material losses.

In FIG. 1 shows a General view of the device in section; FIG. 2 is a view along arrow A in FIG. 1: in FIG. 3 is a view along arrow B in FIG. 2; in FIG. 4 is a view along arrow B in FIG. 1,

The device consists of a bath 1 having an overflow window 2 with a nozzle for removing sediment and a drain window 3 for periodically draining water from the bath 1. In the cavity 1 on the bearings 4, a perforated drum 5 with loading and unloading windows in its end walls is mounted for rotation ( shown in the drawing by arrows) mounted on the shaft 6 with the help of radial blades 7 located at its ends. On the inner surface of the drum 5 a screw 8 is wound to move heavy impurities into the discharge zone. Means for transferring the raw material are formed by inclined vanes 9. The blades 10 serve to discharge the raw materials to the grate tray 11. The screw 8 is equipped with a blade 12 for feeding heavy impurities to the hinged tray 13 mounted on the bath 1 with the possibility of introducing it into the cavity of the drum 5. On an outer surface of the drum 5 has an auger 14 for discharging sludge into the removal zone, which is equipped with a scraper 15 for feeding sludge into the overflow window 2. The drum is driven by a drive chain 17 located in the guides 16 from the bracket not 18 of the engine 19. The chain is tensioned by a roller 20 and a tensioning device 21. The device has a water supply manifold in the form of a nozzle with a nozzle 22. The tray 23 serves for supplying raw materials.

The device operates as follows.

Vegetable raw materials (for example, root crops) go through the tray 23 into the rotary drum 5, where they are twisted by the blades 7 and 9 and moved into the liquid in the discharge zone to the unloading blades 10 and the tray 11. The heavy impurities are discharged by the screw 8 to the blade 12 and tray 13. which is inserted into the drum 5 only when listening to the knock of stones falling from the scapula 12 (or periodically). Contaminated liquid and sediment pass through the perforation of the drum, discharged by auger 14 and a scraper 15 in

overflow window 2. Pure liquid enters through the nozzle with nozzle 22 and is sprayed onto the unloaded root crops. The water is completely drained through window 3. The constant torque from the drive to the drum is provided by a spring-loaded roller 20, and the chain 17 is periodically tensioned by the chain 17 by the tensioner 21.

The efficiency of the working process is provided by increasing the reliability of the washing and separation of heavy impurities, increasing the reliability of the device design itself, as well as reducing losses of vegetable raw materials and more rational use of water.
