RU218589U1 - 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. The combined device for washing and grinding root crops contains a hollow body with a loading funnel, 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. The feed screw is installed in the housing cavity. On the front part of the auger helicoid, knives are installed in a checkerboard pattern, a replaceable grinding body made in the form of a knife and 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 for root crops, made in in the form of a round metal plate, on the upper surface of which 8 counter knives are perpendicularly located at an angle of 45 ° relative to each other. 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 screw helicoid in the area under the nozzles is made perforated. The presence of perforation on the helicoid of the auger 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 device for washing and grinding root crops is known (Patent RU No. 205244, publ. 05.07.2021 Bull. No. 19), including a hollow body with a hopper, diametrically on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body there are nozzles, slots are made in the lower part of the body of the washing zone, the feed auger is installed in the cavity of the body, knives are installed in a checkerboard pattern on the front part of the helicoid of the auger, a replaceable grinding body is made in the form of a knife and fixed on the shank of the shaft installed coaxially inside the feed auger, with the possibility of joint or independent rotation relative to the latter, the unloading window, covered by a deck for root crops, made in the form of a round metal plate, on the upper surface of which 8 counter knives are perpendicularly located at an angle of 45 ° relative to each other, 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 to the drain pipe.

The disadvantage of this device is not enough high quality washing of root crops.

The purpose of the utility model is to improve the quality of washing root crops.

This goal is achieved by the fact that the screw helicoid in the area under the nozzles is made perforated.

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 separation plate for root crops with a cross section A-A.

The combined device for washing and grinding root crops contains a hollow body 1 with a loading funnel 2, nozzles 3 are located diametrically on the horizontal axis of symmetry of the body 1 at an angle α to the vertical axis of symmetry of the body 1. Slots 4 are made in the lower part of the body 1. The feed screw 5 is installed in housing cavities 1. On the front part of the helicoid of the screw 5, knives 6 are installed in a checkerboard pattern, the replaceable grinding body 7 is made in the form of a knife and is fixed on the shank of the shaft 8, mounted coaxially inside the supply screw 5, with the possibility of joint or independent rotation relative to the latter. Unloading window 9, covered by a deck for root crops 10, made in the form of a round metal plate, on the upper surface of which 8 counter knives are perpendicularly located at an angle of 45 ° relative to each other. The device is mounted on a frame 11, consisting of four supports, between which a tray 12 is fixed, the bottom of which is made with slopes to the drain pipe 13. The helicoid of the auger 5 in the area under the nozzles 3 is perforated.

Combined device for washing and grinding root crops works as follows.

The root crops loaded into the funnel 2 are fed by the screw 5 forward to the washing zone, pre-crushed by the knives 6, located in a checkerboard pattern on the front part of the helicoid of the screw 5, where they are subjected to intensive treatment with water supplied under a pressure of 6 ... 8 bar by nozzles 3 connected to pump, which, in turn, is connected to the central water supply network. Approaching the unloading window 9, the main grinding of root crops occurs with a knife 7 rotating at the end of the shaft 8. Then the material exits the installation, additionally crushed by the counter knives of the deck 10.

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