This invention discloses a mixing device with a shaft lifting mechanism, relating to the field of mixing equipment. It includes a mixing tank containing a mixing assembly, a lifting assembly, a drive assembly, and a material lifting assembly. The mixing assembly includes a mixing rod, and the lifting assembly can drive the mixing rod to move vertically within the mixing tank. The material lifting assembly includes an inner lifting cylinder and a lifting spiral blade. The mixing assembly also includes an outer lifting cylinder. A mixing channel is formed on the mixing rod, one end of which communicates with the outer lifting cylinder, and the other end is located on the side wall of the mixing rod. The lifting spiral blade is disposed inside the inner lifting cylinder, and the outer lifting cylinder is fitted onto the inner lifting cylinder.
