DEVICE FOR ROTARY INTERNAL SOIL TILLAGE Russian patent published in 2012 - IPC A01B13/16 A01B33/02 

FIELD: agriculture.

SUBSTANCE: device comprises a shaft of a horizontal internal soil milling appliance with cutters, and the shaft is made with cantilevers. The shaft is arranged perpendicularly to the direction of tiller movement and is mechanically connected to two rotary slot cutters. Slot cutters are arranged vertically symmetrically along the direction of the device movement, cutters have actuators. An odd actuator of a cutter is arranged at the angle of 90° to the cutter plane. A cutting edge of the odd actuator is aligned in parallel to the cutter axis. The odd actuator is arranged at the angle of 60-65° to the cutter plane and is aligned in a direction opposite to the odd actuator. The cutting edge of the even actuator is arranged in the plane parallel to the cutter axis of rotation.

EFFECT: structural design will make it possible to provide for decompaction of inner soil levels and their mixing with each other both in direction of device movement and in transverse direction with high quality, reliability and low energy inputs.
