Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of processing of agricultural products; it can be used for washing and grinding of root crops. The combined plant for washing and grinding of root crops contains a hollow case with a hopper, sidewalls of which have a hinged mount in the upper part of the hopper with walls of the hopper rigidly attached to a grinder case, a feeding auger installed in the cavity of the case, a grinding organ and an unloading window covered with a deck with through holes. The plant includes a washing zone, in which rotary nozzles are located diametrically on the horizontal axis of symmetry of the case at an angle α to the vertical axis of symmetry of the case. Slots are made in the lower part of the case of the washing zone. The plant is mounted on a frame consisting of four supports, between which a pallet is fixed, the bottom of which is made with slopes to a drain pipe. The plant includes a closed-cycle water purification system.

EFFECT: invention will reduce labor intensity, increase productivity and ensure savings in water consumption when preparing feed from root crops.

Description

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

A screw chopper of root crops is known (Patent RU No. 177361, publ. 19.02.2018 Bull. No. 5), including a hollow body with a hopper, the side walls of which are hinged in the upper part of the hopper with the walls of the hopper rigidly attached to the chopper body, a feed auger, installed in the cavity of the body, grinding body and unloading window, covered by a deck with through holes.

The disadvantage of this installation is the inability to wash root crops.

The purpose of the invention is to expand the technological capabilities of the installation by combining the processes of washing and grinding root crops.

This goal is achieved by the fact that the installation includes a washing zone, in which rotary nozzles are located diametrically on the horizontal axis of symmetry of the housing at an angle α to the vertical axis of symmetry of the housing, slots are made in the lower part of the housing of the washing zone, the installation is mounted on a frame consisting of four supports between which the tray is fixed, the bottom of which is made with slopes to the drain pipe, the installation includes a closed-cycle water purification system.

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

In FIG. 2 shows a right side view of a combined plant for washing and grinding root crops.

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

The combined unit 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 housing 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 installation includes a washing zone, in which rotary nozzles 12 are located diametrically on the horizontal axis of symmetry of the housing at an angle α to the vertical axis of symmetry of the housing. Slots 13 are made in the lower part of the housing of the washing zone. tray 15, 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 accumulative 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.

Settler 17, deep pump 18, slotted filter 19, final (fine) filter 20, storage tank 21 and pressure booster module 22 constitute a closed-loop water treatment system.

The combined plant 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 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, 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 in the installation of a washing zone with a closed-cycle water purification system will reduce labor intensity, increase productivity and save water consumed when preparing feed from root crops.

The use of rotary nozzles will ensure the supply of a flat powerful jet to the surface of root crops, due to which a scraper effect will be provided, as a result of which the efficiency of washing root crops will increase with economical use of the consumed liquid.
