DEVICE FOR CREATION OF DEEP LOOSE SOIL LAYER Russian patent published in 2013 - IPC A01B13/16 A01B33/02 

FIELD: agriculture.

SUBSTANCE: device comprises two rotary slot cutters located vertically symmetrically along the direction of the device movement, and connected mechanically to a common drive. The device comprises a rotary intrasoil cutter located below the drive. The cutter shafts are located horizontally and perpendicular to the direction of motion of the ripper. The rotary slot cutter is provided with an annular slot cutter. The device has a pinion, idler, support and center gear wheels, the teeth which engagement is made alternately left and right along the cylindrical surface of the engagement on every detail of the engagement on which they mutually rest with the toothed wheel gearing. The annular slot cutter is provided with cutting elements made on his side surfaces alternately on the left and right, forming capacity for receiving soil. The device is equipped with intrasoil rotary cutter which shafts are located horizontally and perpendicular to the direction of the ripper movement. The rotary slot cutter is equipped with the sun pinion mounted on a separate shaft, located on the frame of the device in the bearings horizontally and perpendicular to the direction of the ripper movement. The annular slot cutter is made in the form of an outer planetary gear. The pinion, idler, support and center gear wheels are made planetary to the sun pinion and the annular slot cutter. The shaft of intrasoil rotary cutter of the lower soil layer is mounted to the idler planetary gears of the rotary slot cutter. The shafts of intrasoil rotary cutter of the topsoil are mounted in the support planetary gears of the rotary slot cutter.

EFFECT: constructive implementation enables to improve the quality of soil treatment by layer by layer loosening the soil.
