Abstract

Usage: when separating the root crops in the sorting and cleaning plants. Vibrators 6 and 7 are placed in each contour of conveyor 2 and 3. The vibrator 7 in the small contour is mounted to interact with the inoperative branch 8. The vibrator 6 in the large contour is mounted outside the action zone of the leading drum 9 of the small contour of the conveyor 3 with the possibility of interaction with the working branch. The vibrators 6 and 7 are installed in the guides 10 and 11 with the possibility of reciprocating movement and working in antiphase one relative of the other. Behind the conveyors 2 and 3, a conveyor 12 is installed for removal of the root-and-vegetable crops, and under the output part of the conveyor 1 there is a conveyor 13 for removing impurities. The vibrators 6 and 7 are located in the guides 10 and 11 also with the possibility of adjusting the operating modes of the brush conveyors 2 and 3 depending on the heap being processed. 2 hp ff, 1 ill. sl C

Description

The invention relates to an agricultural machinery industry, namely to working bodies for separating root crops from impurities during their harvesting and post-harvest processing.

The aim of the invention is to increase the efficiency of the separation of root crops from impurities.

The drawing shows schematically an apparatus for separating the root and tuber crops from lumps of soil and stones.

The unit for separating the roots from the soil and stones lumps contains a finger conveyor 1, above the output part of which the brush conveyors 2 and 3 are installed with opposite rotation with differently sized contours in contact with their working branches 4 and 5. Each rotating conveyor 2 and 3 is equipped with a vibrator 6 and 7. The vibrator 7 is installed with the possibility of interaction with the non-working branch 8 of the conveyor 3 with a smaller contour and is located above the finger conveyor 1. The vibrator 6 is installed above the driving drum 9 m logo circuit with the ability to interact with the working branch 4 of a large circuit. Vibrators 6 and 7 are installed in guides 10 and 11, respectively, with the possibility of height adjustment and antiphase operation.

The unit for separating the roots from the clumps of soil and stones works as follows.

A heap consisting of roots and impurities is fed to the finger conveyor 1, in which the root crops are located at the finger tips, and the impurities, which are more dense than the root and tuber crops, are more deformed than the fingers, are located closer to the base of the finger conveyor 1. Then the pile goes to the counter-rotating conveyors 2 and 3, the pile of which captures the roots and directs them to the conveyor 12 for removal of the roots and crops, and the impurities, overcoming the influence of the pile of the conveyor 3, arrive at conveyor 13 for removal of impurities.

The root crops, pinched between the tufts, are relieved from pinching with the help of vibrators 6 and 7. The operating mode of the vibrators 6 and 7 is adjusted taking into account the size-mass and other physical characteristics of the heap being processed (taking into account moisture, soil type, etc.). The vibrators 6 and 7, each in their guides 10 and 11, can change their location in order to distribute the uniformity of the loads on the transporting surfaces and the steady

technological process, from exposure to constant loads, accelerated wear of surfaces occurs.

In the counter-rotating brush conveyors 2 and 3, self-cleaning of the working surfaces occurs. Under the action of vibrators 6 and 7, the corresponding branches of the conveyors 2 and 3 and due to oscillations of the transporting surfaces of the villus of one branch are embedded in the villi of the other.

branches, thereby clearing the overall surface, while the linear speed of the canvas itself acquires a pulsed character. The impact of vibrators 6 and 7 on the corresponding branches 4 and 8 of the conveyors 2 and 3 in

antiphase with respect to each other enhances the efficiency of cleaning surfaces.

Such an implementation of the unit allows to increase the productivity of work for

by reducing the clogging of the pile, reduce the damage to tubers, reduce the energy intensity of the unit, and the work expended when the conveyor surfaces of the conveyors are contaminated.
