Abstract

FIELD: agriculture.

SUBSTANCE: sowing machine for sowing seeds in drills comprises a frame and a tank with a mechanical stirrer. The mechanical stirrer is provided with a ring with the blades and U-shaped closed elements attached to it to ensure a turbulent flow of liquid in the tank. The blades of the ring are made in the form of an Archimedean spiral. The angle of attack of the blade profile of the U-shaped closed elements is not less than 4°. The mechanical stirrer drive is connected with the support wheel.

EFFECT: use of invention enables to improve the quality of mixing seeds with water and to extend the functional capabilities of the sowing machine.

Description

The invention relates to the field of agricultural engineering and can be used for sowing seeds of vegetable crops.

A known unit for sowing, watering and dusting tobacco seeds. It is mounted on a self-propelled chassis by means of a parallelogram mechanism and consists of a row seed drill of tobacco seeds containing a tank with a mechanical stirrer and a pneumatic stirrer, a distributor and metering tube of the parallelogram mechanism and a device for adding powder to the nutrient mixture containing a hopper with sowing plates (www.vniitti.ru /conf/conf2012/article/VolkovA.A._statya.doc).

The disadvantage of this device is that the mechanical mixer does not provide uniform mixing of seeds with water, therefore, an additional pneumatic mixer is used. This complicates the design and, accordingly, its cost. The disadvantages also include the high speed of the mechanical stirrer.

Known seeder for row seeding of tobacco seeds, containing a bed, a tank with mechanical and pneumatic mixers, a distributor, a sowing pipe and an electric drive, is additionally equipped with a device for providing constant hydraulic pressure of the working fluid, consisting of a mechanism for raising the tank, connected by a lever system with a float located in tank on the surface of the working fluid (RF patent for utility model No. 66665) - prototype.

The disadvantages include the fact that, along with the complexity of the design, the seeder can only be used for sowing tobacco seeds in greenhouses.

These disadvantages are eliminated in the proposed technical solution.

The technical result is to improve the quality of mixing the seeds with water and expand the functionality of the seeder.

The technical result is achieved by the fact that in a seeder for row seeding of seeds, consisting of a bed, a tank with a mechanical stirrer, according to the invention, to ensure turbulent fluid flow in the tank, the mechanical stirrer is equipped with a ring with blades mounted on it, made in the form of an Archimedes spiral, and P- shaped closed elements, the angle of attack of the profile of the blades of which is at least 4 °, and the drive of the mechanical stirrer is in communication with the support wheel.

This embodiment of the seeder has an enhanced prototype property - improving the quality of mixing the seeds with water and expanding the functionality of the seeder.

In the analysis of known technical solutions in this technical field, distinguishing the claimed device from the features of the prototype were not identified, in connection with which they inform the claimed technical solution of the novelty and inventive step.

The essence of the claimed invention is illustrated by drawings.

The figure 1 shows a seeder for row seeding of seeds (side view), figure 2 is a top view, figure 3 is a front view. The mechanical mixer is presented in figure 4. Figure 5 shows the mechanical mixer (type A), in figure 6 - the technological process of the seeder.

The seeder for row seeding of seeds consists of a bed 1 (Fig. 1, 2, 3), a tank 2 with a mechanical stirrer 3. To ensure turbulent fluid flow in the tank 2, the mechanical stirrer 3 is provided with a ring 4 (Figs. 4, 5) with fixed it with blades 5, made in the form of a spiral of Archimedes, and U-shaped closed elements 6, the angle of attack of the profile of the blades of which is at least 4 °, and the drive of the mechanical mixer 3 is in communication with the support wheel 7 (Figs. 1, 2, 3) through intermediate sprockets 8, driven interchangeable sprockets 9 and gearbox 10.

The seeder also contains seed tubes 11 (1, 3), coulters 12, shorting 13 (1, 2, 3), a press wheel 14. To adjust the opening and closing of the material supply valves 15, a lever 16 is used.

The sign “a mechanical stirrer is equipped with a ring with blades fixed on it, made in the shape of an Archimedes spiral” ensures smooth and even mixing of water with seeds in the lower part of the tank for feeding into the seed tubes.

The sign of a mechanical stirrer equipped with "U-shaped closed elements, the angle of attack of the profile of the blades of which is at least 4 °" allows the blades to create a turbulent flow of water. When the angle decreases, the blades move smoothly, which affects the mixing of seeds with water worse.

The sign “drive of the mechanical agitator communicated with the support wheel” makes it possible to use the seeder in the field and greenhouse. It also provides maneuverability.

A seeder for row seeding works as follows. The operator moves the drill in a predetermined direction. When this occurs, the rotation of the support wheel 7, which is transmitted through the intermediate sprockets 8, driven interchangeable sprockets 9 and gearbox 10 to the mechanical mixer 3 (Fig.6). There is a mixing of seeds with water. Next, the operator opens the valves 15 with the lever 16 and through the seed tubes 11 the seeds with water flow into the furrow made by the opener 12. Zagortachi 13 fill the seeds with soil, and the press wheels 14 level the surface.

The use of the invention in comparison with known devices of a similar purpose can improve the quality of mixing the seeds with water and expand the functionality of the seeder.
