To improve the quality of spraying a working liquid, the quality of the process of seed dressing and effectiveness of the operation of dressers a nozzle of an ejector unit is placed into a side piece of the receiving chamber, on the outer surface of the nozzle a ring with openings, connected with a canister by a piping is arranged. From the opposite side of the receiving chamber, coaxial to the nozzle of the ejector unit, a distillation pipe with a run-out is mounted, at the inlet of which a vibrating plate is placed. The run-out is connected with a spiral pipe placed on the outer surface of a cyclone with the filter and the unloading screw.

Description

The invention relates to the field of agricultural engineering, in particular to technical means for treating seeds.

The well-known device for treating seeds (patent NO, Me2138148 SI, IPC 6 АО1С1/00. Device for processing seeds / I.A. Potapenko, G.I. Tretyakov, N.I. Bardak, V.F. Kremyansky, R.A .Gish, V.V. Pushkarsky. -

Me98110755/13; Announced on 06/08/98; Publ. 27.09.1999 Bull. Me27). In the known device, under the influence of sound waves, the seeds repeatedly change their orientation in space when passing through the housing, which increases the optimality of seed processing, and the acceleration of chemical reactions under the influence of acoustic vibrations allows the device to be used for pre-sowing seed processing.

The disadvantages of such a device are the complexity of the design, the presence of a direct current source, a generator of sound vibrations and vibration emitters. In addition, the device does not fully provide highly dispersed spraying of the working fluid and, as a result, insufficiently uniform coverage of the surface of the seed material.

The invention aims to improve the quality of the spraying of the working fluid, the seed treatment process itself, and the effectiveness of the treatment agents.

The task set by the invention is achieved by the fact that in the device for etching seeds, which includes a receiving chamber, according to the invention, the nozzle of the ejector unit is installed in the side of the receiving chamber, on the outer surface of the nozzle there is a ring with holes connected by a pipeline to the tank, on the opposite side of the receiving chamber, coaxially with the nozzle of the ejector unit, an expansion pipe with a diffuser is installed, at the entrance of which a vibrating plate is placed, the diffuser is connected to a spiral pipe placed on the outer surface of the cyclone with a filter and a discharge auger.

Application of sprayed working liquid (poison chemical solution) to the seeds in the etching chamber, in which a stream of compressed air is supplied to spray the working liquid, which enters through the nozzle ring and with the subsequent supply of seed material from the hopper, is carried out in an acoustic field, which is created by a jet of compressed air, which is fed into the receiving chamber through the nozzle of the ejector unit onto a metal plate with the simultaneous supply of the working fluid to this chamber through a ring with holes, which is installed on the outer surface of the nozzle and seed material from the hopper, and finishing etching in the accelerating spiral tube with subsequent separation in the cyclone through a filter with the remains of the sprayed working fluid from the poisoned seed, which is directed to the lower part to the unloading auger.

Fig. 1 shows a scheme of the device for etching seeds, Fig. 2 shows a scheme of the ejector unit with a vibrating plate.

The device consists of a tube 1 to which compressed air from the compressor is supplied, a nozzle 2, a receiving chamber 3, a vibrator 4, a hopper 5 for seed material, a tank b for the working fluid, a pipeline 7, an acceleration tube 8, a diffuser 9, a spiral tube 10, a cyclone 11, filter 12, unloading auger 13. The spiral tube 10 is placed on the outer cylindrical surface of the cyclone 11.

On the surface of the nozzle 2, there is a ring 14 with holes for supplying the working fluid to the receiving chamber C from the tank 6 through the pipeline 7, on the opposite side of the receiving chamber 3, coaxially with the nozzle 2 of the ejector assembly, an accelerating pipe 8 is installed, at the entrance of which a vibrating plate 15 is placed .

The device for etching seeds works like this. Compressed air is supplied from the compressor through tube 1 to nozzle 2. At the same time, the working fluid from the tank 6 through the pipeline 7 is supplied to the ring 14, and then it enters the receiving chamber C and is atomized due to the action of the air flow and the acoustic field created by the oscillations of the plate 15. The seed material is fed into the receiving chamber 3 from the hopper 5. To prevent hanging and the formation of a vault, a vibrator 4 is installed. The sprayed fine liquid evenly covers the surface of the seeds. Under the action of the jet stream of air, the seed moves into the acceleration pipe 8, where its speed increases. In the diffuser 9, the pressure increases slightly, and the speed decreases.

Next, the poisoned seed material enters the spiral part of the pipe 10, and then into the cyclone 1.1, in which the seeds fall down, and the air passes through the filter 12 and goes outside. The poisoned seed is fed into bags, a vehicle, etc. by the unloading auger 13.

In the proposed design of the seed treatment device, compared to the prototype, in the created acoustic field, the working fluid is finely dispersed and droplets are evenly applied to the surface of each seed, under the action of the jet flow in the spiral tube, complete seed treatment is ensured, and the gaseous fraction (air) is separated in the cyclone. and treated seeds, thereby increasing the reliability of the seed treatment process, ensuring the stability and uniformity of seed surface coverage with the sprayed working fluid. . pitra Komash SCHI AS Z y, mnyvy TSO NI Kn no NN shi machines p NI an z y y er
