DISK PLOUGH Russian patent published in 2008 - IPC A01B5/00 

FIELD: agriculture.

SUBSTANCE: disk plough includes a frame with the installed spherical disks and regulating knives, a foot wheel with the depth regulating mechanism and hitch which attaches the tool to the tractor. The regulating knives are made in the form of flat disks. They are installed in front of the spherical disks at a distance providing the combination of leading edge traces of the flat and spherical disks in the direction of plough motion on the soil surface which in its turn is equal to the distance from the soil surface trace of the spherical disk edge to a vertical plane passing through the centre of the spherical disk edge circle, parallel to the direction of a motion. It is determined by the formula: , where R is a radius of the spherical disk edge circle (mm), a is disk landing (mm); α is the angle between the rotation axis of the spherical disk in its vertical position and the direction of motion (degrees); θ is the elevation angle of the rotation axis to the horizontal plane (degrees).

EFFECT: quality of soil treatment with the crop residue increases while power capacity of the treatment process decreases.
