SELF-PROPELLED SOIL MELLOWING APPARATUS Russian patent published in 2006 - IPC A01B9/00 A01B11/00 

FIELD: agricultural engineering, in particular, equipment for soil mellowing without turning of soil layer.

SUBSTANCE: mellowing apparatus has frame, power plant, caterpillar-type propeller with supporting rollers, tracks, and teeth. Propeller comprises two sections. Teeth are made in the form of detents staggered on tracks. Propeller sections are spaced from one another by gap equal to width of one section. Each of propeller sections is made triangular in vertical cross section. Wheel-sprocket is disposed in upper corner of each section of propeller and rigidly joined to frame and connected to reducer. Wheel-sprocket has radius equal to that of supporting roller disposed in opposite corner of section. Supporting roller positioned in corner between wheel-sprocket and supporting roller, which are equal in radius, have radius twice the radius of wheel-sprocket and supporting roller. Mellowing apparatus has supporting rollers located so that their positions in vertical plane may be adjusted.

EFFECT: increased efficiency by providing surface mellowing of soil without turning of soil layer upon self-propelling of mellowing apparatus.
