SOIL LOOSENING TOOL Russian patent published in 2019 - IPC A01B35/22 

FIELD: agriculture.

SUBSTANCE: soil loosening tool comprises a post and a bit. On the opposite side of the bit there are two dampening elements rigidly attached to the post on its opposite sides, on which three holes are made along their length at equal distance from each other for attachment of wings installed opposite to each other in one horizontal plane. Between the post and damping elements there are elements adjusting the grip width on both sides of the post. Post is made in the form of strip, front part of which from lower horizontal part of rack through sock is made in the form of five sections, conjugated to each other. First section with rise of 30° relative to horizontal part of post, smoothly conjugated with second, having lifting in 40° relative to horizontal part of post. Lengths of the first and second sections are equal. Third section is vertical. It is conjugated with the fourth section, which is rounded with radius equal to 1/2 of rack thickness, and height of 1/4 of rack height. Fourth section is smoothly conjugated with fifth height 1/2 of the rack height. Back part of the rack, the length of which is equal to 3/4 of its height from its upper cut, is made similarly to its frontal part. Lower 1/4 of the post is vertical. Bit is made in form of shaped strip, lower horizontal section of which changes into first upper section with rise to 20°, second upper section with rise to 30° and third upper section with lifting in 40° relative to horizontal section. Lengths of these sections are equal to 1/3 of the bit top height each. Ratio of the lengths of the sections of the lower part of the bit and the length of its lower horizontal part is 1:2:1.3. Lower horizontal section of the bit is located in one plane with wings.

EFFECT: higher quality of soil treatment with its various physical and mechanical characteristics, exclusion of collection of weeds and their roots at the point of transition from bit to stand, low resistance during treatment of soil at a depth of more than 60 mm.
