Description

The utility model relates to agricultural engineering, in particular to devices for dressing seeds, and can be used in the processing of grain and leguminous crops both independently and as part of production production lines.

There are known dressing chambers of a presowing seed treatment device, containing a housing connected to the working solution supply line with an unloading window and a loading window with a dosing device, in which the seed flow guides are located in the form of guide plates arranged in a checkerboard pattern with an inclination towards each other, and a solution sprayer ( see USSR Inventor Certificate No. 174019 according to IPC A01C 1/06, published on 08/06/1965 and RF patent No. 2223623 according to IPC A01C 1/08, published on February 20, 2004).

The closest in technical essence is the treatment chamber of the device for presowing seed treatment, containing a housing connected to the supply line of the working solution with an unloading window and a loading window with a dosing device, in which the seed flow guides are located in the form of guide plates arranged in a checkerboard pattern with an inclination towards each other , and located in the lower part of the housing on the counter flow of supplying seeds parallel to the bottom of the device housing, a solution sprayer made in the form of a tube with a jet and a Laval nozzle, and the guide plates are made of mesh, located oppositely and obliquely at angles of 45-50 °, the bottom of the housing is made under an angle of 120-135°, and the bottom of the hopper inside the body is mesh (see RF patent No. 2223623 according to IPC A01C 1/08, publ. 20.02. 2004.).

The disadvantages of the known camera is the low quality of seed treatment and the high probability of injury to the seeds. The disadvantages are due to the fact that the working solution is sprayed under high pressure from the lower part of the housing upwards through the holes of the mesh guide plates, which increases the degree of injury to the seeds, as well as the high probability of clogging on the mesh guide plates and incomplete envelopment of the seeds with the working solution.

The technical result is an increase in the quality indicators of seed treatment, a decrease in the injury rate of seeds, the creation of a continuous range of productivity, the provision of prompt and accurate adjustment of the supply of seed material during processing without interrupting the processing process.

The technical result is achieved by the fact that in the dressing chamber, which contains a housing connected to the working solution supply line with an unloading window and a loading window with a dosing device, in which the seed flow guides are located in the form of guide plates arranged in a checkerboard pattern with an inclination towards each other, and spray nozzles, according to the utility model, the housing is connected to the working solution supply line through inlet pipes fastened with spray nozzles located with the possibility of directing the spray torch into the seed dressing zones between the guide plates with the working solution applied to the seed material across the entire width of the dressing chamber. The dosing device is made in the form of a dosing valve with a graduated opening/closing scale. The body is made with a rectangular cross section.

The essence of the utility model is illustrated by a schematic drawing.

The pickling chamber contains a body 1 with loading 2 and unloading 3 windows, connected to the line for supplying liquid substances for pickling through the inlet pipes 4 with spray nozzles 5 inserted into the wall of the body 1.

The loading window 2 is equipped with a metering valve 6. Inside the housing 1 there is a seed flow guide in the form of guide plates 7 having a smooth surface, obliquely arranged alternately one under the other, forming a zigzag channel for moving the seeds. The angle of inclination of the guide plates 7 exceeds the average angle of repose of the seeds. Etching zones 8, 9 and 10 are located between the guide plates 6. The housing 1 is made with a rectangular cross section. The metering valve 6 is made with a graduated opening/closing scale.

The proposed camera works as follows.

Depending on the type of seeds and the working solution used, the required rate of application of the disinfectant is set, using a dosing valve 4 with a graduated opening / closing scale, the dosing valve 4 is opened, ensuring that a given amount of seeds enters the upper part of the housing 1 from the storage hopper (not shown in the drawing). The seeds move along the body 1 by gravity towards the unloading window 3. When moving, the seeds alternately fall on the guide plates 7. Under the action of the friction force, the movement of the seeds slows down and they turn over in space. The angle of inclination of the guide plates 7 exceeds the average angle of repose of the seeds and prevents clumping and congestion when spilling. The guide plates 7 are sequentially arranged with an inclination towards each other in such a way that the flow of seeds is always poured evenly across the entire width of the dressing chamber.

The cascade of guide plates 7 ensures that the seeds are turned over during transshipment to each subsequent plane, while applying the working solution on different sides of the seeds.

In the process of movement, the seeds are treated with a working solution sprayed by spray nozzles 5 with the required consumption rate, connected to the working solution supply line (not shown in the drawing).

The working solution is sprayed by means of spray nozzles 5, the spray torches of which are directed to the seed dressing zones 8, 9 and 10, treating the seeds across the entire width of the housing 1 perpendicular to the flow of the awakening seeds.

When moving the seeds towards the unloading window 3, the seeds are intensively mixed with the working solution, followed by removal from the chamber through the unloading window 3 into the storage bin (not shown in the drawing), followed by bagging.

Guide plates 7 provide uniform distribution of seed material in the plane; increase the time spent by seeds in the dressing chamber without interfering with their free movement, contribute to the mixing of seeds and the most uniform application of the working solution to the seeds, providing better treatment of the moving seeds, increasing the percentage of its coverage with the working solution.

The proposed design of the dressing chamber allows you to mix the seeds without mechanical impact on it, minimizing seed damage, simultaneously apply solutions of different drugs without mixing with each other, and also scale the pre-sowing seed treatment devices by adding additional sprayers and guide plates.

The tests showed the achievement of the technical result.

During the tests, the application rate of the working solution was from 5 to 25 liters per ton of seeds. The processing capacity is from 6 to 16 tons per hour with a working solution application rate of 10 l/ton.

The use of the proposed treatment chamber of the presowing seed treatment device allows to reduce injury, prevent the formation of congestion in the treatment chamber and improve the quality of seed treatment.
