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. Since rotary blades have axial component speed, tilled soil clods will be destroyed mainly by rightward pulling force applied by rotary blades, and the tilled soil clods are mainly thrown to cultivated land. Thus, the invention can reduce secondary tillage and energy consumption. In addition, the invention can avoid interference among gearbox, bearing seat and untilled soil, so the blade roller can easily sink into the ground to achieve deep tillage.
