METHOD OF SLOPE LANDS CULTIVATION BY SUBSOILER Russian patent published in 2024 - IPC A01B79/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to mechanization of agriculture and can be used in soil treatment on slopes with formation of intrasoil walls. At slope of 5 to 20 degrees, the thickness of the subsoil wall is determined by the mathematical expression b=h · tan(pi/4 − φ/2) · k_s, where h is processing depth; φ is angle of internal friction of untreated soil; k_s—safety factor. With the distance between the subsoil walls L equal to the working width of the aggregate B, the pair of rotary stands moves apart by the distance b, turns at angle β equal to slope incline, and is installed on the first transverse beam along its center. Further, the slope is processed according to the shuttle scheme; at that, when the unit moves in the opposite direction, the turning angle of the rotary stands changes by the angle β in the opposite direction. At distance L equal to 2B, a pair of rotary posts is set to the extreme position on one of the sides and the first padding is performed as described above. At the second paddock during forward stroke tillage is carried out without device of internal soil wall, and at back stroke loosening is performed with formation of inner soil wall on external side of pen.

EFFECT: reduced wash-off of the fertile layer on the slope with guaranteed stability of the slope, prevention of slippage of the upper soil layer to the base of the slope and the impossibility of formation of swampy areas.
