Description

The utility model relates to the field of processing agricultural products and can be used for washing and chopping root crops.

A combined unit for washing and chopping root crops is known (Patent RU No. 2769664, published 04.04.2022 Bulletin No. 10), including a hollow body with a loading funnel, 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, a feed auger installed in the cavity of the body, each turn of the helicoid of the feed auger is formed by two sickle-shaped knives with cutting edges made on the end arcuate working face and along the outer periphery, a chopping element made in the form of a knife, an unloading window covered by a deck, 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-loop water purification system.

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

The technical result of the utility model is an improvement in the quality of root crop washing.

The specified technical result is achieved by the fact that the sickle-shaped knives on the section of the auger under the rotary nozzles are formed by fragments of a steel spiral belt connected to the auger shaft by spokes.

A combined device for washing and chopping root crops comprises a hollow body 1 with a loading funnel 2, rotary nozzles 3 are arranged diametrically 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. A feed auger 5 is installed in the cavity of the body 1, each turn of the helicoid of the feed auger is formed by two sickle-shaped knives formed by fragments of a steel spiral belt 6 with cutting edges 7 made on the end arcuate working face and along the outer periphery, connected to the shaft of the auger 5 by spokes 8. A chopping element 9, made in the form of a knife, an unloading window covered by a deck 10. The deck 10 is made in the form of a round separating plate with through holes of different sizes. The feed screw 5 and the grinding element, made in the form of a knife 9, are driven by means of a gearbox 11. The device is mounted on a frame consisting of four supports 12, between which a tray 13 is fixed, the bottom of which is made with slopes towards a drain pipe 14. Through the drain pipe 14, the waste water enters a settling tank 15, from which a deep pump 16 first feeds it into a slot filter 17, then into a final (fine) filter 18 and subsequently into a storage tank 19. From the storage tank 19, under pressure created by a pressure boosting module 20, the purified water is fed to the rotary nozzles 3.

The settling tank 15, the deep pump 16, the slot filter 17, the final (fine) filter 18, the storage tank 19 and the pressure boosting module 20 make up a closed-loop water purification system.

The combined device for washing and chopping root vegetables works as follows:

Root crops, entering from loading funnel 2 into hollow body 1, moving along feed screw 5, are subjected to intensive treatment with water supplied under pressure of 6...8 bar by rotary nozzles 3 connected to a closed-loop water purification system.

Simultaneously with washing, the root crops are subjected to the action of two sickle-shaped knives located on the feed auger 5.

The process of destruction can be imagined as the work of a wedge in crushing and breaking.

In general, the process of separating the first part of the root crop from the main part can be represented as follows:

at the first moment, the tips of both knives “enter” the body of the root crop to a certain depth and experience the action of forces, while each tip of the sickle-shaped knife acts differently:

one of the sickle-shaped knives will generally act as an instantaneous center of rotation (fulcrum), and the other will press the smaller part of the root crop away from the larger one, simultaneously rotating the root crop around the said center; the next moment, the same sickle-shaped knife will advance into the partially rotated root crop and enter even deeper until the destruction process is complete;

as a result of the separation of part of the root crop from the main mass, the remaining part changes its position relative to the sickle-shaped knife (due to rotation) and comes under the action of the following knives after half a turn and so on until it acquires dimensions comparable to the dimensions of the auger channel.

The material then exits through the discharge window and, if necessary, can be further crushed with a knife, with the degree of crushing being regulated by a deck 10 with a correspondingly sized through sector or number of knife blades 9.

The production of sickle-shaped knives on the auger section under the rotary nozzles in the form of fragments of a steel spiral belt connected to the auger shaft with spokes will improve the quality of root crop washing and reduce the metal consumption of the device.
