UNIVERSAL SOIL TILLAGE DEVICE OF THE COMBINED IMPLEMENT Russian patent published in 2022 - IPC A01B35/26 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The universal tillage device of the combined unit contains a cultivator share (1), the wings of which are made of an arcuate shape. On the basis of the paw (1) of the cultivator, three slots (2) are evenly located with a height at least less than the depth of tillage by the paw (1) of the cultivator. The slitter (2) is made with the possibility of turning in the horizontal plane by 180°. Behind the share (1) there is a mini-harrow (3), rigidly fixed on two rods (8), interconnected by a bar (9) with holes, which is rigidly fixed with countersunk bolts on a common stand with a cultivator share (1). The mini-harrow (3) is made in the form of a welded frame structure (4), the distance between the longitudinal sides of which is at least not less than the width of the paw (1) of the cultivator, and between the transverse sides - 15 ... 20 cm. On the front transverse side of the frame (5) five teeth (6) are fixed: two at its ends and three between them, and on the rear transverse side of the frame (7) - four teeth (6) in a checkerboard pattern with respect to the front transverse side of the frame (5). The ratio of the width of the share (1) to the distance between the teeth (6) of the mini-harrow (3) is 4:1, and the ratio of the thickness and length of the tooth (6) is 1:5. The section of the tooth (6) is made in the form of a rhombus with an acute angle of 30°.

EFFECT: improved quality of tillage.
