Description

The invention relates to the field of agriculture, in particular to machines for processing crops, namely, machines for separating families-j electrification of transverse transverse mixtures. ^. .......

An electroselectronic cleaning machine is known, including a feeder, a vibrating sieve, an electrode placed above it in the form of a closed conveyor with an electrically conductive perforated tape and a suction system confuser installed between the branches of the conveyor C1].

The disadvantage of this machine is the coronation of the sharp edges of the holes at high working stresses, which negatively affects the separation process.

The closest to the invention in terms of technical essence and the achieved effect is an electric seed cleaning machine, including a feeder, a transporting body made in the form of a roller sieve, the rollers of which are grounded and installed from each other at a distance that increases in the direction of unloading, high-voltage rod electrodes placed parallel to the rollers on the middle is not the distance between them, receivers of separation products [2].

The disadvantage of this machine is tribo 10 porter, which reduces the quality of cleaning. In addition, for the manufacture of conveyor belts, high-quality insulating materials are required to ensure good separation due to the sufficient discharge time of adhered particles.

The purpose of the invention is to increase the clarity of the separation of seeds from impurities.

This goal is achieved by the fact that a confuser is installed above the 5’s transporting body, in which rod electrodes are located, between which flow dividers are mounted with the possibility of vertical movement, they can have a dielectric coating.

In FIG. 1 is a schematic illustration of a machine, side view / in FIG. 2, view A in FIG. 1 (location, rod electrodes and flow dividers).

An electric seed cleaning machine consists of a hopper-feeder 1, a transporting organ in the form of an inclined roller sieve 2, the rollers 3 of which are grounded, covered with a dielectric layer and installed from each other at a distance that increases in the direction of discharge. The rollers are installed in a row in groups 4, ... 4p. First one. .

the group are ordinary rollers and there are no electrodes above them. The second and subsequent groups are rollers equipped with washers of a larger diameter, worn on them at equal intervals, the groups are distinguished by the size of the gaps 5. With the exception of the first group, all subsequent ones are covered by a confuser b with flow dividers 7, adjustable in height, arranged in parallel the rod electrodes 8 in and the gaps between them, and the electrodes 8 are installed above the sieve 2 parallel to the rollers 3 in the middle of the distance between them. The dividers 7 are coated with a dielectric and equipped with mechanical rods (not shown) that move them vertically and change the size of the gap 5 (Fig. 1).

The entire system of removal of 6, 7 and 8 of raised particles is located at an angle to the roller conveyor 2 in the direction of discharge of the latter. Under each group of rollers 4 ... 4η there are receivers 9.. . 9p.

Electric seed cleaning machine 30 operates as follows.

From the feeder 1, the seed / mixture enters the inclined roller sieve 2, where, having passed the first group of rollers, it is cleaned of impurities of weeds. 35

Then the seeds, for example, beets, fall into the electrostatic field, where other impurities and inferior seeds are charged with I (as lighter). 'rise in the direction of the rod to the electrodes 8. Under the influence of the air flow of the suction system, all impurities located near the electrodes 8 are discharged by means of a confuser 6. Full-fledged beet seeds fall through the slots of the roller conveyor 2 into the receivers 9. · ..9p. ' The speed of the suction stream is controlled by the vertical movement of the flow dividers 7, i.e. the gap between the electrode 8 and the divider 7. Under the influence of the electric field in these cracks, in addition to pneumatic traction, a ponderomotive force is also formed, which in this case improves the conditions for the separation of beet seeds from impurities, and increases the clarity of separation.
