DISK-TYPE TILLAGE TOOL Russian patent published in 2007 - IPC A01B21/00 

FIELD: agricultural engineering, in particular, overall tillage, row, ridge and hole forming equipment.

SUBSTANCE: disk-type tillage tool has frame consisting of two bars arranged perpendicular to direction of advancement of tillage tool, and spherical disks fixed on bars by means of tines and positioned at an angle to horizontal and vertical planes. Disks of second row are offset in horizontal plane relative to disks of first row by distance equal to half the pitch between disks in row, with convexities of disks of first and second rows facing one another. Gap between rows of disks is equal to or exceeds diameter of disks. Tines with rows of disks are made detachable and are mounted in slots provided through bars for detachment or fixing according to predetermined process to be carried out. Each third slot of front bar for accommodation of disk tine and each third slot, beginning from second slot, of second bar is sized greater than other slots to provide movement of tines positioned therein in direction perpendicular to advancement direction. Tillage tool is equipped with section having flat hoes, said section being mounted on disk frame, rearward of it. Cutting plane of hoes is below cutting plane of disks. Angle of inclination of disks may be adjusted, and disks may be positioned with eccentricity, the value of eccentricity being less than quarter of disk diameter.

EFFECT: wider operational capabilities and increased quality of overall tillage, ridging, hilling and hole forming operations.
