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 chopping root crops is known (Patent RU No. 2769668, published 04/04/2022 Bulletin No. 10), including a hollow body with a hopper, the side walls of which are hinged in the upper part of the hopper with the walls of the hopper rigidly attached to the chopper body , 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 area, a feed auger installed in the cavity of the body, a grinding element and a discharge window covered by a deck with through holes, the device is mounted on a frame consisting of four supports, between which a tray is fixed, the bottom of which is made with slopes towards the drain pipe, the device includes a closed-cycle water purification system.

The disadvantage of this installation is the insufficiently high quality of washing of root crops.

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

This technical result is achieved by the fact that the section of the screw under the rotary nozzles is made of a tape, and the spiral belt in this section is connected to the screw shaft by spokes.

In fig. 1 shows a front view of a combined device for washing and chopping root crops with a closed-cycle water purification system.

In fig. 2 shows a right view of a combined device for washing and chopping root vegetables.

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

In fig. Figure 4 shows a fragment of a belt auger.

A combined device for washing and chopping root crops consists of a hollow body 1 with a hopper 2, the side walls 3 of which have a hinge 4 in the upper part of the hopper with the walls of the hopper 5 rigidly attached to the body 1 of the chopper. In this case, there is a guaranteed gap between the body 1 and the side walls 3 of the hopper 2, which ensures the movement of the side walls 3 of the hopper 2 relative to the body 1. In the case of arching, pressure of the root crop occurs on the side wall 3 of the hopper 2, due to which the side wall 3 is deflected at a certain angle (the limit on the amount of deflection is regulated by stop 6), thereby the root crop is released and, under the pressure of its own weight, falls onto the chopper auger. The pressure force of the root crop depends on the amount of compression of the spring 7.

In the cavity of the housing 1 there is a feeding screw 8, a grinding element 9 made in the form of a knife, and an unloading window covered by a deck 10 with through holes. The device includes a washing zone in which rotary nozzles 12 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. The section of the auger 8 under the rotational nozzles 12 is made of a belt, and the spiral belt 13 in this section is connected to the auger shaft 14 with 8 spokes 15. In the lower part of the body of the washing area there are slots 16. The device is mounted on a frame consisting of four supports 17, between which a tray 18 is fixed, the bottom of which is made with slopes towards the drain pipe 19. Through the drain pipe 19, waste water enters the sump 20, from which the deep pump 21 is supplied first to the slot filter 22, then to the final (fine) filter 23 and subsequently to the storage tank 24. From the storage tank 24, under pressure created by the pressure increase module 25, purified water is supplied to the rotary nozzles 12.

A settling tank 20, a deep pump 21, a slot filter 22, a final (fine) filter 23, a storage tank 24 and a pressure increase module 25 make up a closed-cycle water purification system.

A combined device for washing and chopping root vegetables works as follows.

Root crops, coming from the hopper 2 into the hollow body 1, moving by the feed auger 8, are subjected to intensive treatment with water supplied under a pressure of 6...8 bar by rotary nozzles 12 connected to a closed-cycle water purification system. Simultaneously with the washing, moving by the feed auger 8, the root crops fall under the action of sickle-shaped knives located on the feed auger 8, when moving to the unloading window, larger parts of the root crops along the periphery of the chopper body 1 are further crushed with a knife and exit through the through holes 11 of the deck 10. Degree of grinding regulated by deck 10 with corresponding through holes 11.

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