Description

The invention relates to the field of agricultural engineering, in particular to machines for sowing seeds and simultaneous application of fertilizers.

For the prototype, a section of the seeder was selected, which includes a seed hopper, a sowing machine, harrows, a hopper for loading copolymers with a coil fixed to the bottom of the hopper. The hopper for loading copolymers is connected by means of 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. The activator is installed in the sowing machine. A limiter is fixed above the damper, which prevents the accumulation of hydrogel granules on the damper. In addition, a tank for liquid fertilizers is additionally installed, connected via a hose to a nozzle installed above the damper. The heel of the coulter is adjustable according to the depth of the introduction of copolymers. (Patent of the Russian Federation No. 2732452, published on September 16, 2020).

The disadvantages of this technical solution is the sticking of enriched hydrogel granules on the damper and clogging of the passage above the damper.

The task to be solved by the claimed technical solution is to increase the reliability and improve the performance of the hydrogel supply device.

EFFECT: improved performance of the hydrogel supply device of the seeder section due to the absence of sticking of enriched hydrogel granules and clogging of the passage above the damper.

The technical result is achieved by a seeder section with a hydrogel supply device, which includes a seed hopper, a sowing machine, harrows, a roller, a train, a coulter with installed heels, a hopper for loading copolymers with a coil fixed to the bottom of the hopper, connected by a hose to a damper, which is closed the position is returned by a spring, in addition, a tank for liquid fertilizers is installed, connected by a pipe with a nozzle installed above the damper, and an electric motor is additionally installed, which receives an electrical signal from the sensor with the help of a wire at the moment the seed passes through it, a gear is fixed on the shaft of the electric motor, located in engagement with rails connected by rods with a limiter and a damper, moving towards each other.

The essence of the invention is illustrated by drawings, which show:

In FIG. 1 - General view of the seeder section for sowing vegetable crops with a device for supplying hydrogel installed on it;

In FIG. 2 - Diagram of the hydrogel feeder of the seeder section.

The device is illustrated in Fig. 2, which shows a diagram of the device for supplying the hydrogel section of the planter.

The seeder section includes a hopper for seeds 1, a sowing machine 2, harrows 3, a roller 4, a train 5, a coulter 6 and heels 7, 8. A hopper for loading copolymers 9 with a coil 10 and a hose 11 is installed to the side wall of the seed hopper. Nozzle 12 connected to spring 16 and supplying sprayed liquid fertilizers from liquid fertilizer tank 14 to a portion of copolymers through pipe 13. Sensor 15 is installed in sowing machine 2, which is electrically connected to nozzle 12 and electric motor 19 using wire 23. The hydrogel granule feeder includes an electric motor 19 that receives an electrical signal from the sensor using a wire 23. A gear 20 is fixed on the shaft of the electric motor 19, which engages with the rails 18 and 21 connected by rods 24 and 25 with the limiter 22 and the damper 17 moving towards each other.

The seeder section works as follows.

Before work, the hopper for seeds 1, the hopper for copolymers 9 and the tank for liquid fertilizers 14 are filled. At the same time, the seeds from the seed hopper 1 enter the sowing machine 2. In the lower part of the sowing machine 2, when the seed passes through the sensor 15, an electrical signal is sent to the nozzle 12, which sprays liquid fertilizers through the nozzle 13 from the tank for liquid fertilizers 14 per portion of copolymers located on the damper 17.

An electrical signal through wire 23 is also fed to electric motor 19, with gear 20 fixed on its shaft, engaged with rails 18 and 21, connected by rods 24 and 25 with limiter 22 and damper 17, moving towards each other. Under the action of the pressure of the jet of fertilizers from the nozzle 12, a portion of the copolymers enters the furrow. The shutter 17 under the action of the spring 16 returns to its original position. Harrowers 3 close up the furrow with seeds, the roller 4 rolls it, and the train 5 levels the surface of the field.

Thus, the claimed device for feeding the hydrogel section of the seeder provides an improvement in the performance of the device for supplying the hydrogel section of the seeder due to the absence of sticking of enriched hydrogel granules and clogging of the passage above the damper.
