DISK TILLAGE TOOL Russian patent published in 2010 - IPC A01B21/08 

FIELD: agriculture.

SUBSTANCE: tool comprises frame with even number of transverse bars arranged on it. Vertical knee stands with axes at the ends are mounted on bars in row in bushes, and spherical disks are installed on them at the angle to horizontal plane with the possibility of rotation and synchronous variation of attack angle. Disks in rows are directed with their concave and convex side relative to vertical plane passing through vertical axis of tool frame symmetry and point of its attachment so that in each row on its both sides there is an equal number of oppositely oriented disks arranged at the same distance from each other. Disks in each subsequent row are displaced relative to disks of previous row. Distance in rows between medium differently directed disks is equal to distance between identically oriented disks. Differently directed disks, nearest to plane passing through longitudinal axis of tool frame symmetry and point of its attachment, are arranged in different rows relative to it symmetrically at the distance that equals α/2n, where α is a space between disks in a row, n is number of working elements rows.

EFFECT: such design will make it possible to improve quality of soil cultivation process and efficiency.
