SEEDER SECTION WITH HYDROGEL FEEDER Russian patent published in 2023 - IPC A01C7/04 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to machines for sowing seeds and simultaneous application of fertilizers. The seeder section includes a seed hopper, a sowing machine, harrows, a roller, a trail, 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 returned to the closed position by a spring. There is also a limiter, a tank for liquid fertilizers, connected by a branch pipe with a nozzle installed above the damper, which is driven by an electrical signal from the sensor at the moment the seeds pass through it. The sensor is also electrically connected to the nozzle. The damper drive is made in the form of an electric motor, on the shaft of which a gear is fixed, which is engaged with racks connected by rods with the possibility of setting the limiter and damper in motion towards each other.

EFFECT: invention will improve the reliability of the seeder due to the absence of sticking of enriched hydrogel granules and clogging of the passage above the damper.
