Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of processing agricultural products and can be used for washing and chopping root crops. The combined plant for washing and chopping root crops contains a hollow housing with a loading funnel, a feeding auger installed in the cavity of the housing. On the front part of the helicoid of the auger, knives are installed in a staggered order. The replaceable grinding body is made in the form of a knife and is fixed on the shaft shank mounted coaxially inside the feeding auger, with the possibility of joint or independent rotation relative to the latter. The discharge window is covered by a deck made in the form of a replaceable separating plate. 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 a pallet is fixed, the bottom of which is made with slopes to the drain pipe. The installation includes a closed-cycle water purification system.

EFFECT: invention makes it possible to 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 multifunctionality 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.

Known universal screw-knife feed grinder (Patent RU No. 118835, publ. 08/10/2012 Bull. No. 22), including a hollow body with a loading funnel, a feed auger installed in the cavity of the body on the front of the auger helicoid, knives are installed in a staggered manner, replaceable grinding a body made in the form of a knife and fixed on the shank of a shaft mounted coaxially inside the feed auger, with the possibility of joint or independent rotation relative to the latter, an unloading window, overlapped by a deck made in the form of a replaceable separating plate.

The disadvantage of this installation is the lack of the possibility of washing 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 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, the installation is mounted on a frame consisting of four supports between with which the pallet is fixed, the bottom of which is made with slopes towards the drain pipe, the installation includes a closed-cycle water purification system.

FIG. 1 shows a front view of a combined plant for washing and grinding root crops with a closed-loop water purification system.

FIG. 2 shows a left side view of a combined plant for washing and chopping root crops.

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

The combined installation for washing and grinding root crops contains a hollow body 1 with a loading funnel 2, a feed auger 3 installed in the cavity of the body 1, knives 4 are installed in a staggered manner on the front part of the helical screw 4. The installation is equipped with a replaceable grinding body made in the form of a knife 5 and fixed on the shank of the shaft 6, installed coaxially inside the feed screw 3, with the possibility of joint or independent rotation relative to the latter. The unloading window 7 of the installation is covered by the deck 8, made in the form of a replaceable separating plate. The installation includes a washing zone, in which rotary nozzles 9 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 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 it is fixed sump 12, the bottom of which is made with slopes towards the drain pipe 13. Through the drain pipe 13, the waste water enters the sump 14, from which the deep pump 15 is first fed into the slotted filter 16, then into the final (fine) filter 17 and then into the storage tank 18. From the storage tank 18 under pressure created by the pressure boosting module 19, purified water is supplied to the rotary nozzles 9.

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

The combined plant for washing and crushing root crops works as follows.

The roots loaded into the funnel 2 are fed by the auger 3 forward into the washing area, pre-chopped by knives 4, staggered at the front of the helix of the auger 3, where they are intensively treated with water supplied at a pressure of 6 ... 8 bar by rotary nozzles 9 connected to the system closed cycle water purification. Approaching the unloading window 7, the main crushing of root crops occurs with a knife 5 rotating at the end of the shaft 6. Further, the material leaves the installation, additionally being chopped by the counter blades of the deck 8.

The presence in the installation of a washing zone with a closed-loop water purification system will reduce labor intensity, increase productivity and ensure savings in water consumption when preparing feed from root crops.

The use of rotary nozzles will provide a powerful flat jet to the surface of root crops, thereby providing a scraper effect, which will increase the efficiency of washing root crops with an economical use of the consumed liquid.
