The device is mounted on a frame consisting of four supports, between which a pallet is fixed, the bottom of which is made with slopes towards the drain pipe. The device includes a closed cycle water purification system. The section of the screw under the rotary nozzles is made of tape, and the spiral tape in this section is connected to the screw shaft with spokes.

Making a section of the auger under the rotary nozzles with a belt one will improve the quality of washing root crops.

Description

The utility model relates to the field of processing agricultural products and can be used for washing and grinding root crops.

A combined installation for washing and grinding root crops is known (Patent RU No. 2769662, publ. 04.04.2022 Bull. No. 10), including a hollow body with a loading funnel, rotary nozzles are located diametrically on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body, slots are made in the lower part of the body of the washing zone, a feed screw installed in the cavity of the body on the front part helicoid of the auger, knives are installed in a checkerboard pattern, a replaceable grinding body, made in the form of a knife and fixed on the shank of a shaft mounted coaxially inside the supply auger, with the possibility of joint or independent rotation relative to the latter, an unloading window, covered by a deck for root crops, made in the form of a round metal plate, on the upper surface of which 8 countercutting knives are perpendicularly located at an angle of 45 ° relative to each other, the device is mounted on a frame, with consisting of four supports, between which a tray is fixed, the bottom of which is made with slopes towards the drain pipe, the device includes a closed-cycle water purification system.

The disadvantage of this installation is not enough high quality washing of root crops.

The technical result of the utility model is to improve the quality of washing root crops.

The specified technical result is achieved by the fact that the section of the screw under the rotary nozzles is made of tape, and the spiral tape in this section is connected to the screw shaft with spokes.

In FIG. 1 is a front view of a combined device for washing and grinding root crops.

In FIG. 2 is a left side view of a combined device for washing and chopping root crops.

In FIG. 3 shows a bottom view of the hollow body in the washing area.

In FIG. 4 shows a separation plate for root crops with a cross section A-A.

In FIG. 5 shows a fragment of a belt auger.

The combined device for washing and grinding root crops contains a hollow body 1 with a loading funnel 2, rotational nozzles 3 are located diametrically on the horizontal axis of symmetry of the body 1 at an angle α to the vertical axis of symmetry of the body 1. Slots 4 are made in the lower part of the body 1. The feed screw 5 is installed in the cavity of the body 1. the tape 6 in this section is connected to the shaft 7 of the screw 5 with spokes 8. On the front part of the helicoid of the screw 5 knives 9 are installed in a checkerboard pattern, the replaceable grinding body 10 is made in the form of a knife and is fixed on the shank of the shaft 11 installed coaxially inside the supply screw 5, with the possibility of joint or independent rotation relative to the latter. The unloading window 12, covered by a deck for root crops 13, is made in the form of a round metal plate, on the upper surface of which 8 counter knives are perpendicularly located at an angle of 45° relative to each other. The device is mounted on a frame 14, consisting of four supports, between which a tray 15 is fixed, the bottom of which is made with slopes to the drain pipe 16. Through the drain pipe 16, the waste water enters the sump 17, from which the deep pump 18 is fed first into the slotted filter 19, then into the final (fine) filter 20 and subsequently into the storage tank 21. From the storage tank 21, under the pressure created by the pressure booster module 22, purified water is supplied to the rotary nozzles 3.

Settling tank 17, deep pump 18, slotted filter 19, final (fine) filter 20, storage tank 21 and pressure booster module 22 constitute a closed cycle water purification system.

Combined device for washing and grinding root crops works as follows.

The root crops loaded into the funnel 2 are fed forward by the screw 5 into the washing zone, preliminarily crushed by knives 9 located in a checkerboard pattern on the front part of the helicoid of the screw 5, where they are intensively treated with water supplied under pressure of 6 ... 8 bar by rotary nozzles 3 connected to a closed-cycle water purification system. Approaching the unloading window 12, the main grinding of root crops occurs with a knife 10 rotating at the end of the shaft 11. Then the material exits the device, additionally crushed by the counter knives of the deck 13.

Making the auger section under the rotary nozzles with a belt one will improve the quality of root crops washing.
