Description

The invention relates to the field of agricultural engineering, in particular to machines for sowing vegetable crops.

Known section seeder for group seeding of seeds, connected to the frame of the seeder by means of a four-link hinge-lever system. The section includes a body with a seed box, a seeding device, a coulter. It is connected by a link to the body. The section also has a harrow, a roller and a train. The sowing device is made in the form of an endless belt equipped with cells. It is placed on different-sized master and slave drums. The drive drum is aligned with the drive shaft by means of a chain drive from the support wheels of the seeder. The drive drum is installed above and in front of the driven drum. Above the driving drum is a seed reflector in the form of a loop made of rubberized material. The width of the reflector loop is equal to the width of the endless tape. The sowing section will provide a compact placement of 3-4 seeds in one nest with uniform removal from the seed box. (RU, copyright certificate No. 2280348, M. Cl ³ А01С7-00).

The disadvantage of this section is the lack of fertilization along with the seeds.

Known section of the seeder containing a frame on which mounted spherical roller openers with a single axis of rotation. Each opener is made in the form of two convex discs connected to each other and with a circular knife placed between them. Seed guides are located behind the coulters. A plate-shaped shut-off valve is located under each seed guide. A bushing is mounted on the plate on one side, and a box-shaped profile is mounted opposite it. The edges of the plate and the valve are bent so that their planes make an angle α with the direction of movement of the drill. On the seed guide at the rear, in the direction of the drill, there is a bracket for the stop valve shaft. Above the valve axis, a spring-loaded stop is attached to the guide. The valve is mounted on an axis with a displaced center of gravity and the ability to rotate through an angle close to 180 °. This design allows to improve the quality and reliability of the coulter section. (RU, copyright certificate 2177215, M. Cl ³ А01С7-20).

The disadvantage of this section of the seeder is that the design does not provide for the simultaneous application of fertilizers along with the seeds.

Known section of the seeder design Burkova L. N., which contains a hopper for seeds and fertilizers, seeding devices for them and fertilizer lines of disc openers. A transfer case is installed under the seeding units. It has two parts. One part is connected with a fertilizer-seed pipe for sowing fertilizers, the other with a fertilizer-seed pipe for sowing seeds. The coulter discs are made of different diameters. The fertilizer coulter disc has a diameter larger than the seed coulter disc. The first is installed in front of the latter in one longitudinal-vertical plane. A screed is installed between them. The bar has tides opposite each opener. The tides have triangular bevels from their middle to the edges. The invention will improve the nutritional conditions for seeds and increase their germination (RU, copyright certificate 2256315, M. Cl ³ А01С7-00).

The disadvantage of this section is the lack of dosed fertilizer supply.

For the prototype, a standard section of the SUPN-8 seeder was chosen, which includes a seed hopper, a seeding device, a coulter, a heel, harvesters, a roller and a train.

Its disadvantage is the lack of metered fertilization at a given distance along with the seeds.

The objective of the invention is to increase the yield of vegetable crops by introducing a certain amount of enriched copolymers simultaneously with the seeds.

The technical result is the simultaneous dosed application of vegetable seeds and enriched copolymers.

The specified technical result is achieved by the seeder section, which includes a seed hopper, a sowing device, harvesters, a roller, a trail, a coulter and a heel, while a hopper is additionally installed for loading copolymers with a coil attached to the bottom of the hopper, while the hopper is connected with a hose to a damper, which is connected by a spring to an activator that receives an electrical signal from a sensor when seeds pass through it, which is installed in the seeding device, and a limiter is fixed above the damper that prevents the accumulation of hydrogel granules on the damper, in addition, a tank for liquid fertilizers is additionally installed, connected through a hose with a nozzle installed above the shutter, while the heel of the opener is regulated according to the depth of copolymer application

The invention is illustrated by drawings. FIG. 1 Planter section (side view). FIG. 2 Damper.

The seeder section includes a seed hopper 1, a sowing device 2, a harrow 3, a roller 4, a train 5, an opener 6 and a heel 7. The heel 7 of the opener 6 is adjustable according to the depth of copolymer application. A hopper for copolymers 8 with a reel 9 is installed to the side wall of the seed hopper. The hopper for copolymers 6 is connected with a hose 10 to a shutter 11. A nozzle 12 is installed in front of shutter 11, which feeds a portion of copolymers through a hose 13 with liquid fertilizers in spray form from a liquid fertilizer tank 14. A limiter 15 is installed above the damper to prevent the accumulation of saturated particles of copolymers. A sensor 16 is installed in the metering device 2, which is electrically connected to the nozzle 12 and the activator 17, which is connected by the spring 18 to the flap 11.

The seeder section works as follows.

Before work, the seed hopper 1, the copolymer hopper 7 and the liquid fertilizer tank 14 are filled. The heel 7 of the opener 6 is adjustable in depth.

From the bunker for copolymers 8, a reel 9 through a hose 10 to the valve 11 is supplied with a portion of copolymers. At the same time, the seeds from the seed hopper 1 enter the sowing device 2. In the lower part of the sowing device 2, when the seed passes through the sensor 16, an electric signal is sent to the nozzle 12, which sprays liquid fertilizers through the hose 13 from the liquid fertilizer tank 14 for a portion of copolymers located on the damper 11.

The electrical signal is also fed to the activator 17, acting through the spring 18 on the shutter 11. Under the action of the pressure of the stream of fertilizers from the nozzle 12, a portion of the copolymers enters the furrow. In this case, the limiter 15 prevents the accumulation of saturated particles of copolymers. The flap for supplying a portion of copolymers 11 under the action of the spring 18 returns to its original position.

The harvesters 3 fill the seed furrow, the roller 4 rolls it in, and the train 5 levels the field surface.

Thus, the claimed design of the section of the seeder for vegetable crops provides for the simultaneous metered application of vegetable seeds and enriched copolymers.
