Rectangular stirring drilling machine
The invention relates to a rectangular stirring drilling machine. During work, a motor drives a short drill rod E through a transmission case to drive a drill bit to rotate, the drill bit stirs cement paste and soil injected by a grounding device to a circular pile in a rotation process, meanwhile, the transmission case drives four long knives of the outer end of a short drill rod A and four long knives of the outer end of a short drill rod D to rotate clockwise, the transmission case drives four long knives of the outer end of a short drill rod B and four long knives of the outer end of a short drill rod C to rotate counterclockwise, the force balance of the transmission case is achieved, and the long knives of the outer ends of the short drill rod A, the short drill rod B, the short drill rod C and the short drill rod D and multiple knife teeth of each long knife stir the soil and the cement paste in the rectangle outside the circular pile to form a rectangular cement and soil pile body.
