[0002] Concrete is a composite material made by mixing various materials such as cement, sand, water and admixtures in a specific ratio and then hardening it over a certain period of time. It is the most widely used artificial civil engineering material in the world. Concrete can be classified according to its use into structural concrete, mass concrete, waterproof concrete, heat-resistant concrete, expansive concrete, radiation-proof concrete, road concrete, etc. Concrete has high hardness, a wide range of raw material sources, and low cost, and is widely used in structures such as houses, highways, military engineering, and nuclear power plants.

[0003] Among them, the utility model patent with announcement number CN220945991U discloses an automated concrete proportioning and feeding device. However, the above patent still has some shortcomings in use. It cannot mechanically measure and feed materials, making feeding more troublesome. Moreover, its mixing effect needs to be improved, which is not conducive to the accurate proportioning of concrete. Therefore, we propose a concrete proportioning and feeding mechanism to solve the above problems. Utility Model Content
