PRECISION SOWING MACHINE-CULTIVATOR FOR PRECISION SOWING Russian patent published in 2021 - IPC A01B49/06 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to soil cultivating sowing units with working elements intended for accurate sowing of seeds on stubble ground background and levelling of field surface with compaction of soil. Seeder-cultivator of accurate seeding includes sowing sections with lever opener coulters, seed hopper with seed ducts, supporting wheels, rear press-wheel coverers and chain drive of seeding unit, connected by seed pipes with duck couplers of ploughshares.

Latter are mounted between support wheels and press-wheel coverers of rollers. Frame of sowing machine-cultivator is made in the form of central beam with hingedly connected to it right and left branches. Left and right thrust wheels are mounted on the frame front outlets. Pairs of press-wheel coverers are mounted on rear taps. Support wheels and wheels of press-wheel coverers are connected to the frame outlets by means of double-acting hydraulic cylinders. Wheels of each pair of press-wheel coverers are mounted on different axes, which are offset relative to each other in horizontal plane by 0.6–1.0 of wheel diameter.

EFFECT: invention will make it possible to increase reliability of work and uniformity of seeding depth.
