WEEDING CUTTER Russian patent published in 2014 - IPC A01B33/10 

FIELD: agriculture.

SUBSTANCE: weeding cutter consists of a shaft with discs and blades rigidly attached to it. The blades are made of thin, durable and wear-resistant steel and are attached to the discs so that they form angles α with line of motion of the weeding cutter and angles β with tangents to the cylindrical surface in which they are located. The discs are made in the form of regular hexagons and are attached to the shaft rotated by 30° relative to each other. The blade edges are attached to adjacent discs through the angle tops so that given the turn of the discs it is 90°. This provides reduction of angles α to 17° and increase in the angles β to 25°.

EFFECT: improvement of quality of weeding and increase in productivity.
