The device contains a bunker 1, one of the walls 2 of which is hinged and oscillates due to the action of the cam 3, the fan 4, the separation chamber 5. The device is equipped with flaps 9, 10 and the device 11, which in a certain position relative to the separation chamber and each other provides a wide range of adjustments separating the properties of the air flow, which provides high-quality cleaning of impurities for a year with different fractional content, humidity, etc. 2 hp ff, 1 ill.

Description

The invention relates to agricultural machinery and is intended for cleaning berries from impurities.

The purpose of the invention is improving the quality of cleaning and expanding technological capabilities.

The drawing shows a schematic diagram of the proposed device.

The device comprises a loading hopper 1, one of the walls 2 of which is pivotally mounted and has an oscillation mechanism in the form of a cam 3, a fan 4, a separation chamber 5 with a window 6 for supplying berries to the separation chamber, a window 7 for exiting peeled berries and a pipe 8 for litter discharge .

Between the fan 4 and the outlet window 7, a shutter E is pivotally mounted to change the direction of the air flow. A continuous shutter 10 is pivotally mounted behind the exit window 7, the hinge axis of which has the possibility of permutation in the vertical plane, which makes it possible to additionally change the aerodynamic qualities.

Between the fan 4 and the separation chamber 5, devices 11 in the form of small dampers with a variable angle of inclination are installed on the air flow path to increase the heterogeneity of the air flow by changing the direction of its different layers. Fan 4 is driven by a manual drive (not shown). The separation chamber 5 and the pipe 8 form a separation channel, throughout which separation occurs; a mixture of berries with litter on the main and cork fractions.

Wall 2 is made with the possibility of changing its length, in order to regulate the number of berries supplied to the separation chamber.

The device operates as follows.

Fan 4 is driven into rotation. Through the drive (not shown), the cam 3 starts to rotate at the same time, as a result, the wall 2 oscillates. Unrefined berries are loaded into hopper 1. Here they are shaken by wall 2, listened, and litter is partially separated from the berries. Then the mixture enters the separation chamber 5. The amount of the supplied mixture is regulated by the sliding part of the wall

2. The mixture entering the separation chamber through the window 6 is picked up by the air flow created by the fan 4 and the devices 11 crushed into separate jets, shaken vigorously, blown and divided into fractions depending on the aerodynamic properties. The berries fall either directly into the container for pure berries, or onto the shutter 10 and slide down into it into the container for pure berries. The dampers 9 and 10 are installed in such a position that the bulk of the air passes slightly above the damper 10. This allows you to increase the power of the air flow, its separation capabilities, since the berries that are on the damper 10, there is less ejection force,

Berry heap, depending on the conditions of collection and transportation to the place of purification, may have different separability into a valuable fraction litter. To establish the best regime for cleaning berries (high productivity, the lowest content of litter in peeled berries and the lowest emission of berries with litter), a test cleaning is carried out during which all necessary adjustments are made. Having set the device to the optimal mode, they begin to clean the entire batch of berries. During the cleaning process, the quality of cleaning is regularly monitored and, if necessary, the separation is adjusted by slight changes in the position of the shutters 9 and 10 and the device 11, as well as by a change in the fan speed.

The power and structure of the air flow generated by the device can be changed within wide limits. Therefore, the device has wide technological capabilities, since it is possible to peel not only berries of various degrees of weediness and moisture, but also similar products,
