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 cavity of the body, knives are staggered 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, an unloading window, overlapped 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 section of the screw under the nozzles is made as a belt, and the spiral belt in this section is connected to the screw shaft with spokes. Making the section of the auger under the nozzles with a belt 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 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 hopper, 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, in the lower parts of the body are slotted, the feed auger is installed in the cavity of the body, knives are staggered 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 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 technical result of the utility model is to improve the quality of washing root crops.

The specified technical result is achieved by the fact that the section of the screw under the nozzles is made of tape, and the spiral tape in this section is connected to the screw shaft with knitting needles.

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 fragment of a belt auger.

A 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 screw is installed in the cavity of the body 1 5, the section of which under the nozzles 3 is made of tape, and the spiral tape 6 in this section is connected to the shaft 7 of the screw 5 with knitting needles 8. On the front of the helicoid of the screw 5, knives 9 are installed in a checkerboard pattern. The replaceable grinding body is made in the form of a knife 10 and fixed on the shank of the shaft 11, mounted coaxially inside the feed screw 5, with the possibility of joint or independent rotation relative to the latter. The unloading window 12, covered by a deck 13, made in the form of a replaceable separating plate, the device is mounted on a frame 14, consisting of four supports between which a pallet 15 is fixed, the bottom of which is made with slopes to the drain pipe 16.

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, pre-chopped by knives 9, 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 12, the main grinding of root crops occurs with a knife 10 rotating at the end of the shaft 11. Then the material exits the device, additionally crushed by the counter knives of the deck 13.

Making the section of the auger under the nozzles with a belt will improve the quality of washing root crops.
