RU219364U1 - COMBINED DEVICE FOR WASHING AND GRINDING ROOTS - Google Patents

Abstract

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

Combined device for washing and grinding root crops, contains a hollow body with a loading funnel, in which 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, a feed auger is installed in the cavity of the body on the front part of the 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 the shaft installed coaxially inside the feed auger and kinematically connected to it by means of a two-stage cylindrical gearbox, an unloading window covered by a deck made in the form of a replaceable separating plate. 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 the 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. 2769661, publ. 04.04.2022 Bull. No. 10), including a hollow body with a hopper, in which rotational 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; knives, 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 and kinematically connected to it by means of a two-stage cylindrical gearbox, an unloading window covered by a deck made in the form of a replaceable separating plate, the device is mounted on a frame consisting of four supports between which the bottom is fixed with slopes to the drain pipe, the device includes a closed-loop 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 fragment of a belt auger.

Combined device for washing and grinding root crops, contains a hollow body 1 with a hopper 2, in which rotational nozzles 3 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. ohm 7 of the auger 5 with spokes 8. On the front part of the helicoid of the auger 5, knives 9 are installed in a checkerboard pattern. separating plate. The device is mounted on a frame 15, consisting of four supports, between which a tray 16 is fixed, the bottom of which is made with slopes to the drain pipe 17. Through the drain pipe 17, the waste water enters the sump 18, from which it is fed by a deep pump 19 first into the slotted filter 20, then into the final (fine) filter 21 and subsequently into the storage tank 22. From the storage tank 22, under the pressure created by the pressure booster module 23, purified water is supplied to the rotary nozzles 3.

Settling tank 18, deep pump 19, slotted filter 20, final (fine) filter 21, storage tank 22 and pressure booster module 23 constitute a closed cycle water treatment 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 13, the main grinding of root crops occurs with a knife 10 rotating at the end of the shaft 11. Further, the material exits the device, additionally crushed by counter-cutting knives of the deck 14.

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