DISK TILLAGE DEVICE Russian patent published in 2013 - IPC A01B49/02 A01B21/08 

FIELD: agriculture.

SUBSTANCE: device comprises a frame adapted for connection to a traction facility with longitudinal and transverse bars. On the bars there are stands fixed with discs of spherical shape frontally along the entire width of grip. Discs are installed as capable of rotation and control of the angle of attack, and their axes are inclined to the earth surface plane under the sharp angle. The frame is arranged as capable of control of the value of discs deepening and is equipped with a transport wheeled mover, and also levelling, controlled rollers or modules of rollers. Rollers or modules of rollers may be arranged, for instance, of spiral type, moreover. Discs in rows are directed with their concave or convex side to the longitudinal axis of device symmetry so that the number of discs of each row at both sides is identical. In adjacent rows the discs are displaced by a number equal to a quotient from division of the disc-to-disc space into number of rows. The unit frame is arranged in the form of a central centre girder, on which transverse bars are installed. Transverse bars carry stands with fixation of bandage type and working discs. Inner ends of transverse bars are fixed to the beam with the help of hinged joints of cardan type, and their outer ends - to transverse bars with the help of axes of hinged joints, forming parallelogram sections. Sections are equipped with tightening screws to control the angle of attack of the discs, and also with front support wheels, which limit depth of front row discs cutting-in. The beam comprises a helical jacking mechanism of lifting and lowering of a draft coupler. On the beam there are working spherical discs mounted as directed towards each other with concave sides for soil treatment in the central zone of grip width.

EFFECT: structural design will make it possible to increase reliability of a soil tillage device due to simplification of its design, to increase repairability and to reduce power inputs for soil tillage.
