DEVICE FOR ROTARY INTERNAL SOIL RIPPING Russian patent published in 2009 - IPC A01B33/02 

FIELD: agriculture.

SUBSTANCE: device comprises two rotary slot cutters arranged vertically symmetrically along direction of device motion. Slot cutters are mechanically connected to common drive and have shafts arranged horizontally and perpendicularly to direction of ripper motion. Under drive there is an internal soil miller. Rotary slot cutter is equipped with disk of slot cutter and circular slot cutter. Disk of slot cutter comprises master, slave, support and aligning gears of drive, engagement teeth of which are arranged alternately on the left and right along external cylindrical surface of each gear. On master, slave, support and aligning gear and on circular slot cutter there is a cylindrical support surface, circumferential diametre of which is equal to diametre of according circumference of engagement. Circular slot cutter is equipped with engagement teeth arranged on its side surfaces alternately on the left and right directed towards its internal cylindrical surface. By means of cylindrical surface, circular slot cutter interacts with geared engagement arranged on external cylindrical surface of master, slave, support, aligning gears of drive. Circular slot cutter is equipped with cutting tools arranged on its side surfaces alternately on the left and right and directed towards its external cylindrical surface.

EFFECT: such structural design will make it possible to perform simultaneous arrangement of two slots in soil for water absorption, decompaction and mixing of internal soil layers with preservation of humic layer, strubble and glass cover onto soil surface, to increase device reliability and to reduce energy inputs.
