Description

The invention relates to the field of mechanization of agricultural production, in particular to methods that allow cleaning during root crops during their transportation.

A device is known that includes the extraction of root crops from the soil, their transportation, cleaning and unloading, carried out individually from each row. After extracting root crops from the soil, they are oriented in the longitudinal direction with the heads forward [1].

The disadvantages of this device is the decrease in the quality of cleaning root crops due to their uneven interaction with the rods of the brush.

A device is known consisting of a separating conveyor comprising a frame, a cascade elevator bed, enveloping the driving and driven sprockets and lower bypass rollers, and at least one additional upper element located between the lower rollers. Moreover, each additional bypass element is made in the form of a downward directed nozzle connected to a source of compressed air [2].

The disadvantage of this device is the complex construction of the conveyor, having a cylinder with screw winding, which is located inside the conveyor and can be very dirty during operation.

Closest to the proposed device is a device that includes the supply of a pile of root crops to the cleaning working bodies and their interaction with the elements of the cleaning working bodies made in the form of brushes and their further unloading [3]. Brushes are cleaned of soil with a coiled coil spring. The spring is arranged parallel to the axis of the brushes, which makes a longitudinal reciprocating vibrational movement along the axis of the brushes, with the possibility of self-cleaning of the spring.

The disadvantage of this device is that the root crops entering the head for cleaning are not uniformly cleaned from all sides.

The purpose of this utility model is to improve the quality of cleaning root crops during harvesting in conditions of high soil moisture through the use of a brush cleaner.

To achieve this goal, a device is proposed consisting of two elements of a brush cleaner located above the drive roller conveyor.

The essence of the invention is illustrated by the scheme, where:

FIG. 1 is a diagram of a device for cleaning root crops (side view),

FIG. 2 is a diagram of a device for cleaning root crops (top view).

The device (Fig. 1) contains a welded frame 1 having a roller conveyor 5 (Fig. 2), which is driven by an engine 2 that transmits torque through the coupling 3 to the gear 4. The gear 4 has a chain gear on the output shaft, which transmits torque to the conveyor shaft 5. Above the conveying elements, two drive cylindrical brush drums 7 with elastic pile are installed. The drums 7 are installed in the racks 6 and are driven by a belt drive 8 (Fig. 2). Above one brush drum is a coiled coil spring of wire of circular cross section 9. In addition, the racks have openings, which allows you to change the position of the spring in a vertical plane relative to the roller conveyor 5.

In the process, the dug root crops are transported by the conveying element to the zone of action of the driving brush drums 7 with elastic pile, which rotate and clean the root crops from sticking soil.

This design provides high-quality cleaning of root crops without damage due to copying their surface with bristles of the brush cleaner.
