[0002] Concrete, referred to 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, mixed with water in a certain proportion, and obtained by mixing. It is also called ordinary concrete. Concrete mixing equipment is a machine that mixes cement, sand and stone aggregates and water to make concrete mixture;

[0003] However, after the concrete mixing equipment puts in raw materials in appropriate proportions, the concrete raw materials are mixed through a single mixing rod combined with the spiral inner wall of the concrete mixing equipment. However, the sizes of the raw materials such as sand and gravel put in are different, and heavier materials such as sand and gravel will sink to the bottom better than materials such as water, resulting in low overall concrete mixing efficiency, which has brought certain adverse effects on actual use, and therefore needs to be improved.
