Abstract: An oblique submerged reverse deep rotary tilling device configured to be connected to a tractor. The tilling device includes a stander, a mounted frame, a gearbox and an oblique blade roller. The oblique blade roller has configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and an advancing direction of the tractor is 55˜70° while the rotary blade tips are all toward the right side of the advancing direction. Side force balance blades are installed to the left side of the oblique blade roller, rotate in a plane that is parallel to the advancing direction, and have a rotating center axis disposed at an angle to the oblique blade roller to balance the axial component force of the oblique blade roller.

Abstract: This invention provides an oblique submerged reverse deep rotary tilling device, which includes a stander, a mounted frame, a gearbox and an oblique blade roller. However, the oblique blade roller is mainly made up of configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and the traction speed is 55˜70° while the rotary blade tips are all toward the right side of the traction speed. Side force balance blades are installed to the left side of the oblique blade roller and used to balance the axial component force of the oblique blade roller. The working pattern of this invention is an oblique submerged reverse rotary tillage method. Therefore, there is no soil restriction on the top of the tilling soil clod. Meanwhile, due to cutting soil configured regularly, the right-side soil has been cut when the rotary tilling blades soil begins tilling. The soil is mainly destroyed by tension.
