[0002] As the main material of modern construction, the quality and performance of concrete are of vital importance. Traditional concrete mixing devices have many problems, such as uneven mixing, high energy consumption, and low efficiency. These problems not only affect the quality of concrete, but also increase production costs and time. With the development of the construction industry and the improvement of environmental protection requirements, the demand for efficient, energy-saving, and environmentally friendly concrete production mixing devices is becoming increasingly urgent. Therefore, improving the technology and methods of concrete mixing devices has become an urgent problem to be solved.

[0003] After massive searches, it was found that the prior art publication number is CN213617494U, which discloses a material mixing device for concrete production with good mixing effect. The first motor and the second motor are set to make the first fan blade and the second fan blade rotate in opposite directions to mix and stir the concrete, and the inclination angle of the first fan blade and the second fan blade are both forty-five degrees, and they are inclined towards each other, which solves the problem that the concrete is thick and requires a lot of force to stir it.
