RU218576U1 - 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 the grinding of root crops.

The combined device for washing and grinding root crops contains a hollow body with a hopper, the side walls of which are hinged in the upper part of the hopper with the hopper walls rigidly attached to the chopper body. 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. Feeding auger installed in the body cavity, grinding body and unloading window covered by a deck with through holes. 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 helical surface of the screw in the area under the rotary nozzles is made with perforation.

The presence of perforation on the helical surface of the auger will improve the quality of root crops washing.

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. 2769668, publ. 04.04.2022 Bull. No. 10), including a hollow body with a hopper, the side walls of which are hinged in the upper part of the hopper with the hopper walls rigidly attached to the grinder body , 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, a grinding body and an unloading window covered by a deck with through holes, the device is mounted on a frame consisting of four supports, between which a tray is fixed, the bottom of which is made with slopes to 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 screw helicoid in the area under the rotary nozzles is made perforated.

In FIG. 1 is a front view of a combined root washer and grinder with a closed circuit water purification system.

In FIG. 2 is a right 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.

The combined device for washing and grinding root crops consists of a hollow body 1 with a hopper 2, the side walls 3 of which are hinged 4 in the upper part of the hopper with the walls of the hopper 5 rigidly attached to the chopper body 1. At the same time, there is a guaranteed gap between the body 1 and the side walls 3 of the hopper 2, which ensures the movement of the side walls 3 of the hopper 2 relative to the body 1. (limitation of the deviation value is regulated by stop 6) thereby the root crop is released and under the pressure of its own weight falls on the chopper auger. The pressure force of the root crop depends on the amount of compression of the spring 7.

In the cavity of the body 1 there is a feed auger 8, a grinding body 9 made in the form of a knife and an unloading window covered by a deck 10 with through holes. The device includes a washing zone, in which rotary nozzles 12 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 13 are made in the lower part of the body of the washing zone. The device is mounted on a frame consisting of four supports 14, between which a pallet 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 supplied first to the slotted filter 19, then to the final (fine) filter 20 and subsequently to the storage tank 21. From the storage tank 21 under pressure created by the pressure increase module 22, purified water is supplied to the rotary nozzles 12.

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.

The combined device for washing and grinding root crops works as follows:

Root crops, coming from the hopper 2 into the hollow body 1, moving by the feed screw 8, are subjected to intensive treatment with water supplied under a pressure of 6 ... 8 bar by rotary nozzles 12 connected to a closed-cycle water purification system. Simultaneously with the washing, moving by the feed auger 8, the root crops fall under the action of sickle-shaped knives located on the feed auger 8, when moving to the unloading window, the larger parts of the root crops along the periphery of the chopper body 1 are crushed with a knife and exit through the through holes 11 of the deck 10. Degree of grinding regulated by deck 10 with corresponding through holes 11.

The presence of perforation on the helical surface of the auger will improve the quality of root crops washing.
