COMBINED TILLAGE UNIT Russian patent published in 2006 - IPC A01B49/02 

FIELD: agricultural engineering.

SUBSTANCE: combined tillage unit has frame with carrier wheels, adjustment mechanisms, disk batteries, flat hoes, bladed drum, and bar-toothed roller. Arrangement line of outer disk batteries is offset backward from arrangement line of middle disk batteries by distance equal to half the diameter of disk of batteries. Flat working tools, bladed drum and bar-toothed roller are rigidly fixed on longitudinal shafts. Ends of longitudinal shafts are positioned for rotation and displacement in vertical U-shaped guides rigidly attached at internal side of frame. Longitudinal shafts of first three rows of working tools are rigidly connected with one another through member arranged under frame and attached thereto. Working tools are arranged on surfaces of bladed drum and bar-toothed roller in helical lines of multithread screw and connected with one another through ribs, which define regular polygon in transverse plane. Working edges of drum blades are made toothed and triangular. Blade teeth are bent relative to one another at an acute angle along the entire length of working edge of blade.

EFFECT: reduced sizes of tillage unit and improved quality of tillage of soil.
