Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of processing 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 loading funnel, a feeding auger installed in the cavity of the case. Knives are staggered on the front part of the helicoid of the auger. A replaceable knife for grinding of root crops is fixed to a shaft shank mounted coaxially inside the feeding auger with the possibility of joint or independent rotation relatively to the latter. The plant contains an unloading window overlapped by a deck made in the form of a replaceable separating plate. 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 and grinding root crops. The versatility of the proposed device is ensured by the presence of a washing zone, as well as the use of a replaceable rotating knife and a replaceable separating plate.

A universal auger-knife feed chopper is known (Patent RU No. 118835, publ. 10.08.2012 Bull. No. 22), including a hollow body with a loading funnel, a feed auger installed in the body cavity on the front of the helicoid of the auger, knives are installed in a checkerboard pattern, a replaceable knife for grinding root crops, fixed on the shank of a shaft installed coaxially inside the supply auger, with the possibility of joint or independent rotation relative to the latter, an unloading window covered by a deck made in the form of a replaceable separating plate.

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 left side view of a combined plant 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 knife for chopping root crops with a cross section A-A.

Combined installation for washing and grinding root crops contains a hollow body 1 with a loading funnel 2, a feed screw 3 installed in the cavity of the body 1, knives 4 are staggered on the front of the helicoid of the screw. The installation is equipped with a replaceable grinding body, made in the form of a knife 5 for grinding root crops and a shaft 6 fixed on the shank, mounted coaxially inside the feed screw 3, with the possibility of joint or independent rotation relative to the latter. Knife 5 for grinding root crops is made in the form of a metal plate with rounded ends, four knives are attached to the upper surface of the knife at its opposite ends at an angle of 40-45° to the side end surfaces, each of which is made in the form of a triangular profile plate. The unloading window 7 of the installation is covered by a deck 8 made in the form of a replaceable separating plate. The installation includes a washing zone in which, diametrically on the horizontal axis of symmetry of the body at an angle a to the vertical axis of symmetry of the body, rotary nozzles 9 are located, slots 10 are made in the lower part of the body of the washing zone. The installation is mounted on a frame consisting of four supports 11, between which a pallet is fixed 12, the bottom of which is made with slopes to the drain pipe 13. Through the drain pipe 13, the waste water enters the sump 14, from which the deep pump 15 is fed first into the slotted filter 16, then into the final (fine) filter 17 and subsequently into the storage tank 18. From the storage tank 18, under pressure created by the pressure increase module 19, purified water is supplied to the rotary nozzles 9.

Settling tank 14, deep pump 15, slotted filter 16, final (fine) filter 17, storage tank 18 and pressure booster module 19 constitute a closed-loop water treatment system.

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

Root crops loaded into funnel 2 are fed by auger 3 forward into the washing zone, pre-chopped by knives 4 located in a checkerboard pattern on the front of the helicoid of auger 3, where they are intensively treated with water supplied under a pressure of 6 ... 8 bar by rotary nozzles 9 connected to the system closed-loop water treatment. Approaching the unloading window 7, the main grinding of root crops occurs with a knife 5 rotating at the end of the shaft 6. Then the material exits the installation, additionally crushed by counter-cutting knives of the deck 8.

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.
