Description

DEVICE FOR SEED MANAGEMENT.

The utility model relates to agriculture, in particular, to agricultural machinery - a device for seed dressing.

A device for seed treatment according to the description of the invention to the USSR patent No. 1831E46, class. A 01 C 1/00, published in BI No. 88 07/30/93. (1).

This device is a rotating cylindrical elongated container, inside of which on the walls there are several rows of plates located with some angular displacement relative to each other, which ensures thorough mixing of the treated seeds. Inside the tank are nozzles for supplying a solution of the processing drug.

Also widely known is the universal seed treater PS-10, see the technical description of this device for use, Gatchina, 1976, from 1-10 (2).

A disadvantage of the above known devices is that seed treatment is carried out by mixing, resulting in a simultaneous treatment of seeds with a solution of the drug.

As a rule, these plants are bulky, have low productivity, and due to the fact that the treatment is carried out by thoroughly mixing the seeds with the drug solution, it is necessary to spend a large amount of the solution (up to 10 liters per ton of seeds), in connection with this a significant increase in seed moisture, which does not allow the processing of seeds of spring crops in the autumn-winter period, as it decreases

A 01 C 1/00

processing quality, flowability of seeds decreases, Seeds are processed unevenly and, accordingly, some seeds receive an increased dose of the drug, and others receive a low dose.

The purpose of the proposed utility model, a device for seed dressing is to create an aggregate that uses a controlled grain-air flow, transporting the mass of seeds from the storage hopper to the seed treatment chamber and the discharge hopper.

The specified goal is achieved as follows. Processed seeds are poured into a vertically installed container (storage hopper). The storage hopper is divided into two parts: the upper part is the loading chamber, where grain is fed and accumulated, and the lower part is the intake chamber, into which grain is fed through the dispenser with a slide gate. At the same time, compressed air is supplied to the intake chamber through a perforated (mesh) bottom and a closed chamber, which, when mixed with the mass of grain, gives the mass suspended, i.e. fluidized state, in which the grain mass is easily and gently transported to the pickling chamber and then to the discharge hopper under the influence of air flow (on an air cushion).

The grain intake chamber is connected to a vertically mounted seed dressing (processing) chamber in its lower part by a grain pipeline. And the upper part of the pickling chamber is connected by a pipe to the upper part of the vertically mounted discharge hopper. As a result of the creation of a small vacuum by a vacuum pump in the discharge hopper, grain from the intake chamber through the pipeline in a suspended fluidized state under the influence of compressed air from the chamber on the one hand, and under the influence of a vacuum pump from the discharge hopper on the other hand, is easy and soft on an air cushion without mechanical Injury proceeds first into the pickling chamber, and then into the discharge hopper. In the seed dressing chamber, for example, in two tiers along the inner perimeter of the chamber, many nozzles are installed, of which a finely dispersed aqueous emulsion of the seed treatment solution is continuously supplied. The seeds, passing on an air cushion through the cloud of solution created by the nozzles, are moistened (covered) with the solution of the preparation and the treated ones enter the discharge hopper.

When filling the discharge hopper by about 2/3 of the volume, the treated seeds are unloaded at the bottom of the hopper through the Pipeline using compressed air.

As a distant analogue of the proposed utility model, the invention can be accepted The device for seed treatment according to USSR patent No. 1831246 (1).

The drawing shows a schematic design of the proposed device for seed treatment.

The proposed device consists of the following units, components and parts.

A hopper-filler 2 is fixedly mounted vertically on the frame 1, divided into two parts by a dispenser 3 with a slide gate 4; the upper part of the filling hopper 2 is the loading chamber 5, and the lower part is the seed sampling chamber 6, and a pipe 8 for supplying compressed air under the bottom 7 is connected to the perforated (mesh) bottom 7 of the chamber 6 through the closed chamber 7. The bottom 7 acts as a kind of diffuser of compressed air flow.

Above the perforated bottom 7 of the intake chamber 6 on a certain

the height of the screen 9 is strengthened, which directs the flow of grain into the pipe 10,

- 3 In the seed dressing chamber 11, for example, two nozzles 18 are fixed in two tiers on the inner wall, through which a finely divided aqueous solution of the processing agent is supplied. The seed dressing chamber 11 in its upper part is connected via a pipe 13 to the upper part, which is mounted vertically on the frame 1, of the discharge hopper 14, in the upper part of which a pipe 15 is mounted, which is designed to exhaust air from the discharge hopper 14 and, accordingly, from the seed dressing chamber 11 .

In the wall of the discharge hopper 14 at a level of approximately 2/3 of the total height of the hopper 14, a contact sensor 16 is installed, and below it at a level of approximately 1/4 of the total height of the hopper 14 is a contact sensor 17. These sensors are designed to signal a start or turning off commands to the electro-pneumatic valve, which gives executive commands to open (close) the gate valve 18 and supply compressed air to the pipe 19. Compressed air from the pipe 19, located coaxially with the pipe 20, unloads (pushes) the grain from the bottom discharge hopper 14 through the pipeline 20,

The proposed device for seed treatment works as follows.

A vacuum pump creates a vacuum in the discharge hopper 14. The gate valve 18 is closed, the access of compressed air through the pipe 19 is also blocked. Air is sucked out respectively from the seed dressing chamber 11 and the intake chamber 6. The gate valve 4 is closed, the compressed air through the pipe 8 is also not

serve.

the shutter 4 of the dispenser 3 and through the pipe 8 serves compressed air into the closed chamber under the perforated (mesh) bottom 7 of the intake chamber 6.

The grain entering through the dispenser on the bottom 7 under the influence of compressed air is brought into a suspended, fluidized state, the mass of grain becomes light and mobile, and is guided by the screen 9 under the influence of the air mass draft created by the vacuum pump, as well as the pressure of the compressed air continuously coming from the pipeline 8 is easily and gently transported (lifted) by an air cushion along the seed dressing chamber 11 up into the dressing zone. Here, in a cloud of an aqueous solution of a finely dispersed emulsion continuously supplied under pressure through nozzles 12, the seeds are wetted (covered) with a solution of the preparation and then through the air stream through a pipe 13 they enter the discharge hopper 14 and fall to the bottom of the discharge hopper under their own weight.

As the etched (processed) grain accumulates in the discharge hopper 14 to the level of the contact sensor 16, a command signal is received to open the slide gate 18 and supply compressed air to the pipe 19, as a result of which the grain is unloaded through the pipe 20.

When the grain level is reached during unloading in the unloading hopper 14 to the level of the contact sensor 17, a command signal is received to turn off the compressed air supply p | the pipeline 19 and, accordingly, closing the slide gate 18.

By all commands during the operation of the entire device, namely, to the control mechanism of the shutter 4, to supply the solution of the processing agent to the nozzles 12, open (close) the gate shutter 18, to supply compressed air to the pipelines 8 and 19, to

The vacuum pump controls the microprocessor. At the same time, the microprocessor selects such an optimal mode of operation of the entire device, in which all units operate continuously for a shift or more, that is, all the grain entering the storage hopper 2 is processed continuously and is also continuously discharged through the discharge pipe 20.

A pilot production sample of the proposed plant for seed dressing was developed, manufactured and tested in work with a positive result in 1999. Plant productivity is up to 40 tons of grain per hour with 100% seed treatment. The proposed device provides high-quality seed dressing with a solution of the drug in a dose of up to three liters per ton of seeds, which is three-odd times less than on devices that are currently operating according to traditional technology, which allows processing of seed material at any time of the year, since the reduced dose of water drug solution (3 l / t) does not lead to a noticeable increase in grain moisture.

Due to the fact that grain processing occurs as a result of its passage through a water-air emulsion of a preparation solution, each grain is covered with a preparation solution in the same planned (predetermined) dosage.
