DEVICE FOR SUBSOIL ROTARY MILLING WITH FORCED CLEANING OF MECHANICAL DRIVE AND ITS CUTTING ELEMENT FROM SOIL Russian patent published in 2014 - IPC A01B13/16 A01B33/02 

FIELD: agriculture.

SUBSTANCE: device comprises two rotary milling chisel ploughs located vertically symmetrically along the direction of travel of the device, mechanically connected to a common driver. The rotary milling chisel plough is provided with an annular milling chisel plough. The annular milling chisel plough is provided with outer cutting elements, provided along its outer side at the side surfaces alternately on the left and on the right. In front of the cutting element a container for receiving soil is made. The container for receiving soil is simultaneously a cavity of engagement of the gear drive on the outer side of the annular milling chisel plough. The container for receiving soil of the annular milling chisel plough is provided with a recess on its rear surface formed parallel to the plane of the annular milling chisel plough between the bottom of the container for receiving soil and the cutting element of the annular milling chisel plough. The rear surface in the direction of rotation of the pinion tooth is provided with a projection which width is 20-30% of the width of the pinion tooth, which lateral plane is made in one plane with the lateral surface of the tooth, directed towards the central plane of the pinion.

EFFECT: this constructive implementation enables to improve cleaning the container for receiving soil of the annular milling chisel plough and the cutting element of the annular milling chisel plough from the extracted soil, to reduce the tractive resistance and energy consumption, to improve reliability of the device.
