FIELD: agriculture.
SUBSTANCE: ridge drill section comprises the suspension 1, the plough beam 2, the gauge-wheel, 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 the ridge formers 14 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 14. The spherical discs are mounted with their convex side to the longitudinal symmetry axis of the roller with the possibility to change the approach angle of the spherical discs symmetrically relative to the longitudinal symmetry axis of the roller at the same angle, the opening of which is directed toward the roller 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. On the convex side of each spherical disc C-shaped rippers are rigidly mounted, in cross-section having the shape of an elongated rectangle and directed with their lesser side towards the longitudinal symmetry axis of the roller. Each C-shaped ripper is directed with its concave side towards the spherical disc rotation, and shaped sharpened recesses in the form of a semicircular are made around the periphery of each spherical disc.
EFFECT: invention will allow to improve the quality of planting tilled crops.
