DEVICE FOR SOWING SEEDS Russian patent published in 2019 - IPC A01C7/16 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to sowing agricultural machinery, intended primarily for sowing non-running seeds of fodder plants. In the method, the device for sowing seeds contains a bunker, sowing coils placed underneath it and bladed blowers installed in the lower part of the bunker above the sowing coils. Said blowers are mounted on a shaft connected to the drive shaft of the metering reels. Each supercharger is made with lamellar blades lying in the same plane, transverse to the shaft of the superchargers. Said blades of the supercharger, preferably, are made in the form of a single three-blade part. There is a gap of no more than 10 mm between the edge of the fan blade and the corresponding sowing coil.

EFFECT: invention increases the efficiency of the blowers by preventing the formation of air voids and arches above the seeding coils and minimizing the resistance to movement of the blades from the seed, has a simplified design, reduced metal content and is universal due to the possibility of its use for sowing bulk materials without dismantling the blowers.
