[0002] Commercial concrete refers to concrete used for commercial purposes, such as concrete that can be sold and purchased. Most of the current building constructions use commercial concrete, which is a general term for engineering composite materials that bond aggregates into a whole by cementitious materials. Usually, the term "concrete" refers to cement concrete, which uses cement as the cementitious material, sand and stone as aggregates; and is mixed with water (with or without additives and admixtures) in a certain proportion, and obtained through stirring, forming, and curing. It is also called ordinary concrete and is widely used in civil engineering.

[0003] In the Chinese patent with the publication number of CN220129117U, a mechanical stirring device for preventing the solidification of commercial concrete is disclosed.

[0004] Although the above device prevents solidification by stirring the concrete with two stirring rods rotating in different directions, this stirring method can only perform horizontal stirring, and the upper-layer concrete and the lower-layer concrete are not remixed. After a long time of placement, the phenomenon of stratification between the upper-layer concrete and the lower-layer concrete is likely to occur. For this reason, we provide a device for preventing the solidification of commercial concrete to solve the above problems. Content of the Utility Model
