SECTION OF SEEDER FOR EXACT DEPTH SOWING OF SEEDS OF AGRICULTURAL CROPS Russian patent published in 2019 - IPC A01C7/20 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to sowing machines for seeds of agricultural crops, providing preset depth of seeds sealing and covering them with moist layer of soil. Seeder section for precision-depth sowing of seeds of crops includes mounted on the drive freely rotating flat knife with flanges, fixed seed guide and furrow-forming working element. Furrow-forming working element is made anchor and is mounted on axle of disk knife by means of leashes. Front part of the furrow-forming working element has a taper, which is conjugated with the cutting edge of the flat knife. Enclosing roller is hinged to furrow-forming working member on spring-loaded drive in the form of two truncated cones oppositely installed by small bases with coverage of truncated cones of groove edge formed by a furrow former with large bases. Latter in lower part is made wedge-like with wedge angle providing seed fixation along furrow axis. Anchor furrow-forming is conjugated with coil sowing apparatus, coil cavities of which are made along multiple screw lines. Coils are installed on the drive shaft with possibility of movement in the axial direction. Drive shaft has a flat.

EFFECT: invention will make it possible to increase accuracy of seeds sealing to the specified depth and, thus, to increase field germination capacity of seeds.
