RIDGE DRILL SECTION Russian patent published in 2017 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: ridge drill section comprises the suspension 1, the plough beam 2, the gauge-wheel 3, the holders 4, 5, 6, and the opener 7. The ridge formers 14 contain a rack, a duck foot shovel, a mouldboard, and a bracket. The mouldboard is made flat and is mounted with the ability to change its position on height along the rack with respect to the cutting edges of the duck foot shovel and the approaching angle in the horizontal plane, as well as to be fixed in the desired position. The mouldboards of each pair of ridge formers are mounted symmetrically with respect to the sown seeds line at angles α, the opening of which is directed towards the movement of the ridge drill section. A ridge-forming roller 31 comprising a composite frame, spherical discs, and bars with springs, is mounted behind the ridge formers. The spherical discs are mounted with their convex side to the longitudinal symmetry axis of the roller 31 with the possibility to change the approach angle of the spherical discs symmetrically relative to the longitudinal symmetry axis of the roller 31 at the same angle, the opening of which is directed toward the roller 31 movement, and to be fixed in a determined position. Between the spherical discs on the axis at regular intervals flat discs are mounted, the outer contour of which is made multifaceted and sharpened bilaterally. Rippers are rigidly mounted on the convex side of each spherical disc, in cross-section having the shape of an elongated rectangle and directed with their lesser side towards the spherical disc rotation. The rippers are circumferentially mounted on the spherical discs, and shaped sharpened semicircular recesses are made around the periphery of each spherical disc.

EFFECT: invention will allow to improve the quality of planting tilled crops.
