Abstract

The invention relates to agricultural machinery and provides for the expansion of the technological capabilities of the device by drying, cleaning the roughage from foreign inclusions before they are distributed to animals. The device contains an endless belt conveyor 2 of a dielectric, on the discharge edge of which there is a w, bushing 3, and under its lower branch is w, a bushing 4. In the process of moving the coarse feed with a conveyor, its tape is electrified with grippers 3 and 4, attracting due to this foreign matter contained in the feed. The combing elements 5 having a zero potential that interact with the brushes clean them from foreign inclusions, which are poured into the container 8. The cleaned feed is transferred by brush 3 onto the conveyor 6. 1 cp f-ly, 1 ill.

Description

The invention relates to agricultural machinery, in particular to devices for electrostatic cleaning of materials from impurities.

The purpose of the invention is the expansion of the technological capabilities of the device by ensuring the cleaning of roughage from foreign inclusions before their distribution to the animals.

The drawing schematically shows a device for electrostatic cleaning of materials from impurities, General view.

The device comprises a hopper 1 and an dielectric electrode made in the form of an endless conveyor belt 2. One edge of the latter is placed under the hopper 1, and a rotating brush 3 interacting with it is mounted on the opposite edge to induce an electric charge in the form of a cylindrical drum. A brush 4 is located under the lower branch of the conveyor; it is made * like a brush 3. The brushes 3 and 4 are equipped with combining neutralizing elements 5 with zero potential, interacting with them. Under the brush .3 there is a conveyor 6 for removal of och- 2 [valuable feed with a capacity of 7, and under the brush 4 - a container 8 for collecting foreign inclusions.

Conveyors 2 and 6 are interlocked using a belt drive 9.

The device operates as follows.

From the hopper 1, coarse feed, such as hay, is loaded onto a conveyor 2, the belt of which is electrified by rotating brushes 3 and 4 and attracts due to this. excessively small particles of food and the foreign inclusions contained in it.

At the same time, the elements 5 neutralize the brushes and clean them mechanically from the trapped foreign inclusions and various impurities, which, together with small particles of feed, are poured into the tank 8. At the same time, the cleaned feed is transferred by brush 3 to the conveyor 6. Larger foreign bodies are poured into the area between transporters.
