Background Art

Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

The concrete mixing equipment used in construction in the related art is generally in the shape of a horizontal drum, and one end is open for loading and unloading materials. The inner wall is fixedly connected with spiral blades, which rotate with the inner wall to achieve mixing when in use. The rotation form is single, and the mixing efficiency and effect need to be improved.
