MULTIPLE-PURPOSE TILLAGE TOOL Russian patent published in 2012 - IPC A01B79/02 

FIELD: agricultural engineering.

SUBSTANCE: invention refers to agricultural engineering, and in particular to multiple-purpose tillage machines for surface mulching tillage and for elimination of weed seeds. The tool includes a frame, rotary operating elements in the form of knives with the functional surface in the shape of a frustum that are fixed on the rotating hubs with spokes. The frame is made in the form of two pivotally connected lateral sections. Unilateral razors are installed on the front cross arm of the frame in front of the first row of the rotary operating knives along the line of digging. They are designed for the maximum running depth of the working elements. The second section of the frame contains screw spiral seedbed rollers made with right and left spiraling. They are placed in two rows and can be adjusted for height. The diameter of the front seedbed roller is twice larger than of the back one.

EFFECT: improvement of the quality of mulching surface tillage and elimination of the weed seeds.
