Abstract

Usage: The invention relates to an agricultural machinery industry and is intended for the post-harvest processing of fruits, for example, tomatoes. SUMMARY OF THE INVENTION: The device includes a feed conveyor separating a cylindrical brush mounted under a similar part of the latter, a conveyor for carrying out separation products, a separating conveyor and rollers mounted one above the other under the feed conveyor with the possibility of counter-rotation and co-movement in vertical and horizontal planes. The lower drum is rotatably mounted in one direction with the separating brush. In addition, the rollers are spring-loaded relative to each other and rubberized, and their surfaces are rough. The separating conveyor is installed with an inclination towards the separating brush, and its working surface is made rough. 1 hp f-ly, 1 ill.

Description

The invention relates to agricultural machinery and can be used for post-harvest processing of fruits, such as tomatoes.

A device for sorting fruits to isolate benign fruits according to their physical and mechanical properties is known.

However, said device has insufficient separation efficiency.

A device for separating fruits from soil lumps and impurities is known, which comprises a feed conveyor with a downward part, under which there is a separating cylindrical brush with a gap. A spring-loaded cylindrical brush guide is installed at the outlet of the feeding conveyor.

A disadvantage of the known device is the possibility of unloading standard fruits behind a large lump of soil and as a result of quenching their kinetic energy in the inclined section of the feeding conveyor that standard fruits fall into the waste fraction,

The aim of the invention is to improve the quality of separation.

The goal is achieved by the fact that a device including a feed conveyor separating a cylindrical brush mounted under a similar part of the latter and a conveyor for carrying out separation products is equipped with a separating conveyor and rollers that are installed under the feed conveyor one above the other with the possibility of counter-rotation and joint movement in vertical and horizontal planes. The lower drum is rotatably mounted in the same direction as the separating brush, resulting in better capture of soil lumps and impurities that are transmitted from the brush. Below, under the rollers and the separating brush, obliquely towards the latter, there is a separating conveyor, the working surface of which is made rough,

To increase the frictional properties of the rollers, they are spring-loaded one against the other and are rubber-coated, and their surfaces are rough.

The drawing shows a diagram of a device for separating fruit from soil lumps and impurities, side view.

The device comprises a feed conveyor 1, separating a cylindrical brush 2 mounted under a similar part of the feed conveyor, which is also provided with a supporting tension roller 3. Under the feed conveyor, one above the other is installed with the possibility of counter-rotation and co-movement in the vertical and horizontal planes of the rollers 4 wherein the lower roller is rotatably mounted in one direction with the separating brush. The location of the rollers is adjusted so that the mixture of soil lumps, standard and defective fruit falls between the rollers (trajectory II).

Under the rollers 4 and the separating brush 2 at an angle of 8-10 ° to the horizon there is a separating conveyor 5 mounted inclined to the side of the brush. The working surface of the separating conveyor is made rough. The device also contains a conveyor of 6 standard fruits and a conveyor of 7 impurities.

The device works as follows.

The heap of fruits is fed by the conveyor 1 to the protruding side of the separating brush 2. The large and part of the middle fruits are separated by the brush 2 and are fed to

standard fruit conveyor b (trajectory I), Unseparated medium and small fruits along with impurities (crushed fruit, leaves, tops) are carried by brush 2 under conveyor 1 to the pick up area of rotating rollers 4 (trajectory II), Standard fruits do not pass between the rollers 4, bounce off, fall onto the separating conveyor 5, roll down its inclined surface downward, are caught by the separating brush 2 and are directed onto the conveyor 6 standard fruits (trajectory III).

Soil lumps and impurities as a result of more friction are captured by rollers 4 and 7 impurities are thrown onto the conveyor (trajectory IV). The soil lumps that have bounced off the rollers fall onto the separating conveyor 5 and transport 7 impurities to them (trajectory V).
