RU219359U1 - 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 feed funnel. On the horizontal axis of symmetry of the housing at an angle α to the vertical axis of symmetry of the housing, nozzles are located. Slots are made in the lower part of the body. The feed auger is installed in the housing cavity on the front part of the helicoid of the auger, knives are installed in a checkerboard pattern, 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, an unloading window covered by a deck made in the form of a replaceable separating plate. 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 helical surface of the screw in the area under the nozzles is made with perforation. The presence of perforation on 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. 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 combined installation for washing and grinding root crops is known (Patent RU No. 2752961, publ. 11.08.2021 Bull. No. 23), including a hollow body with a loading funnel, nozzles are located 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, a feed screw is installed in the body cavity on the front of the helicoid screw ka 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 mounted coaxially inside the supply auger, with the possibility of joint or independent rotation relative to the latter, the unloading window, covered by a deck made in the form of a replaceable separating plate, 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 installation 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 helical surface of the screw in the area under the nozzles is made with perforation.

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.

The combined device for washing and grinding root crops contains a hollow body 1 with a loading funnel 2, nozzles 3 are located on the horizontal axis of symmetry of the body at an angle α to the vertical axis of symmetry of the body, slots 4 are made in the lower part of the body 1. A feed auger 5 is installed in the cavity of the body 1, having a perforation on the helical surface in the area under the nozzles 3. A knife is installed in a checkerboard pattern on the front part of the helicoid of the auger 5 and 6. The replaceable grinding body is made in the form of a knife 7 and fixed on the shank of the shaft 8, mounted coaxially inside the feed screw 5, with the possibility of joint or independent rotation relative to the latter. The unloading window 9, covered by a deck 10, made in the form of a replaceable separating plate, the device is mounted on a frame 11, consisting of four supports between which a pallet 12 is fixed, the bottom of which is made with slopes to the drain pipe 13.

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

The root crops loaded into the funnel 2 are fed forward by the auger 5 into the washing zone, preliminarily chopped with knives 6 located in a checkerboard pattern on the front part of the helicoid of the auger 5, where they are intensively treated with water supplied under a pressure of 6 ... 8 bar by nozzles 3 connected to a 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 auger will improve the quality of washing root crops.
