Description

A device for pelleting seeds refers to agriculture, specifically to agricultural machinery, namely, devices for pre-sowing seed treatment of crops by pelleting. In addition, the claimed utility model can be used for pelleting other objects, for example: sweets, vitamins or medicines.

A device for pelleting seeds is known, containing a frame with an electric motor fixed to it, connected with a drive of the panning working body, feed mechanisms for seed, filler and wetting liquid (see USSR author's certificate No. 1782388, А01С 1/00, dated November 6, 1990, publ. in bulletin No. 47 of December 23, 1992).

The disadvantage of this device is the periodic dragee coating regimen that it implements, which is inconvenient, low-tech, and difficult to automate. In addition, due to the periodic mode of operation, the known device for pelleting seeds is difficult to include in the production line for the preparation of seed material.

The frequency of pelleting in the known device is due to the need for sequentially performing several technological operations:

1) the inclusion of an electric motor for rotation of the coating pan;

2) loading into the panning working body a portion of the original seeds;

3) the addition of a portion of filler (material of the future coating of the dragee) and a wetting liquid to the coating device;

4) waiting for several minutes for uniform adhesion of the filler on the seeds, leading to the formation of partially drazhenny seeds;

5) an increase in the rotation frequency of the coated pane working body to ensure the rotational movements of the panned seeds around its axes (failure to perform this operation leads to the localization of the coated pills in the lower part of the coated pouch, the formation of “empty” pills or the formation of pills with two or more seeds);

6) then follows a three-four-fold repetition of p.p. 3, 4 and 5.

The technical result of the proposed utility model is to achieve a continuous regime of seed pelleting, which significantly increases the usability of the device, determines the possibility of automating the process and increases its productivity. In addition, the device for pelleting seeds according to the claimed utility model greatly simplifies its inclusion in the production line for the preparation of seed material.

This technical result is achieved by the fact that the device for pelleting seeds containing a frame mounted on it with an electric motor, connected to the drive of the coating device, feeding mechanisms for seeds, filler and wetting liquid, is additionally equipped with a receiving hopper, while the feeding mechanism for seeds is made in the form of storage a hopper with a dispenser fixed underneath it, and a drazhirovochny working body - in the form of an installed inclined belt conveyor, above the upper part of the belt there are furs the seed supply, above the inclined part is the filler and wetting fluid supply mechanism, and under the lower part is the receiving hopper, and the direction of movement of the belt of the working part of the conveyor belt is opposite to the direction of movement of the seeds.

In FIG. 1 shows a block diagram of a device for pelleting seeds.

The device for drazhirovanie seeds contains a frame 1 with an electric motor 2 mounted on it, connected to the drive 3 of the coating of the working body 4. As a drive 3 of the coating of the working body 4 can be applied, for example, a mechanical gearbox with a lower gear ratio. Panning working body 4 is a conveyor mounted at an angle of 20 ... 45 ° to the surface of the earth. The installation angle of the coating pan 4 may vary (for example, by means of its articulation with the frame 1). Above the upper part of the tape of the drazhirovochny working body 4 is placed a seed feeding mechanism 5, which is a storage hopper 6 with a dispenser 7. As a storage hopper 6, for example, a box having the shape of a parallelepiped, a truncated pyramid or a truncated cone, facing smaller base down and containing processed seeds. The metering device 7 is located in the lower part of the storage hopper 6. The metering device 7 is a device that provides a piece feed of treated seeds.

A receiving hopper is located under the lower part of the tape of the panning working element 4. Above the inclined part of the tape of the panning working body 4 there is a mechanism 9 for feeding the filler and wetting liquid. The arrangement of the filler and wetting fluid supply mechanism 9 is selected in such a way that the entire inclined (working) part of the tape of the draining working body 4 is in the zone of their action.

The direction of movement of the tape pane coated working body 4 is made opposite to the direction of movement of the panned seeds when they move freely on the tape under the influence of gravity.

A device for pelleting seeds works as follows.

Depending on the type and size of the source seeds, on the chosen mode of pelleting, as well as the materials used filler and wetting liquid, the angle of inclination of the coating of the working body 4 to the surface of the earth through an appropriate connection (attachment) with the frame 1.

The source seeds are loaded into the storage hopper 6 of the mechanism 5 for feeding seeds. The dispenser 7 delivers a piece feed of the source seeds to the upper part of the tape of the coating device 4. Due to the force of gravity, these seeds acquire rotational movements relative to their axes and begin to slide down the inclined part of the tape of the coating device 4.

The electric motor 2 by means of the drive 3 drives the pelleting working body 4. The speed of movement of the tape of the pelleting working body 4 is chosen equal to the speed of movement of the source (drazhirovannyh) seeds. Thus, the position of the seeds relative to the ground or frame 1 remains unchanged (the shift rolls down, and the tape of the dragging working body 4 lifts them up).

The filler and wetting liquid supply mechanism 6 continuously feeds the filler (for example, a mixture of finely ground diatomaceous earth, clay and sand) and wetting liquid (for example, water) to the entire inclined part of the tape of the coating device 4. The seeds located in the upper part of the tape of the coating device 4, intensively rotating in a medium of moist filler, enveloped with filler and turn into dragees (pelleted seeds). The diameter of the dragee gradually increases, and the speed of their translational movement directed downward becomes higher than the speed of the tape directed upward. A slow but accelerating movement of the dragee begins in the direction of the lower part of the tape of the dragee working body 4. The process of seed dragee continues. In place of the partially drazirovannyh seeds moving relative to the frame 1 in the direction of the lower part of the tape of the pelleting working body 4, new initial seeds are dispensed by 7. The displaced partially drazirovanny seeds continue to rotate in a moist filler environment, and the diameter of their shell grows. Having received the given sizes, the finished dragees (fully drazirovannyh seeds) roll down from the bottom of the tape of the dragee working body 4 and fall into the receiving hopper 8.

When changing the speed of movement of the tape of the dragging working body 4, the angle of its installation relative to the surface of the earth, the length of the working part of the tape, the type of filler and wetting liquid, the useful model can be used in the confectionery and pharmaceutical industries in the manufacture of sweets, vitamins or medicines.
