SPHERICAL DISC COULTER Russian patent published in 2024 - IPC A01C7/20 

FIELD: agricultural machine building.

SUBSTANCE: invention relates to sowing machines coulters. Technical result is achieved by the fact that the spherical disc coulter consisting of a spherical disc fixed on a hub with a bearing assembly is mounted on one end of the cross-piece, and on the opposite end of the cross-piece with the help of a stop there is a thrust with an eye having a through horizontal hole, on the other two ends of the cross-piece a fork is hinged, on the bend facing the side opposite to the movement of the coulter, a tubular guide is installed in the hinge for the installation and adjustment of the seed guide with a deflector, the fork is rigidly connected to a post having a round section, which by means of the angle of attack setting mechanism is attached to the frame bar, the post side facing the fork arm, where the tubular guide is fixed, has an inclined hole with a diameter equal to the seed guide outer diameter, adjusting rod is arranged between thrust and post eyes to adjust disc inclination relative to vertical plane. Invention will make it possible to improve quality of sowing of seeds of grain crops by improving the process of sowing furrow formation, uniform distribution of seeds and fertilizers in depth and sowing area, to increase crop capacity and reduce traction resistance during operation of the coulter.

EFFECT: improving the quality of sowing of seeds of grain crops by improving the process of formation of a sowing furrow, uniform distribution of seeds and fertilizers on depth and area of sowing, increasing crop capacity and reducing traction resistance during operation of the coulter.
