DEVICE FOR NONMOLDBOARD TILLAGE Russian patent published in 2020 - IPC A01B13/08 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building, in particular, to devices for continuous nonmoldboard tillage of soil, including on fields having sections which do not pass moisture of atmospheric precipitation. Device for nonmoldboard tillage of soil includes mounted with support wheels welded frame with installed on it bent poles with rippers in the form of bits and removable depending on method of processing duck foot with bolt joints. Welded frame is trapezoidal and has curved in compliance with rack curvature cover plate with loop, spring, spring shock absorber with through coaxial holes of angle pieces. Latter are installed symmetrically behind the chisel and on upper surface of duck foot and are rigidly connected to them by bolt joints. On the upper and lower parts of the post and on the duck foot between the corners there are additional hinges. Strap is connected with the post by the lower part by means of hinges and by the upper part by means of loops through the spring damper it is interconnected with the post. Lower part of the post is installed between the angles and has a hole for possibility of hinged connection with them. Duck foot is connected by means of loops through the spring to the post.

EFFECT: invention will allow to reduce power consumption and metal consumption and improve the quality of soil treatment, namely: to improve leveling of the bottom, and also to increase strength and reliability of the frame structure.
