Background Art

Concrete is a man-made building material made of raw materials such as cement, aggregate, water and admixtures through mixing, pouring, curing and other processes. It has the advantages of good plasticity, durability and convenient construction. It is widely used in construction projects, such as the construction of houses, bridges, roads, tunnels, etc. Concrete mixer is a device used to prepare concrete. It mixes raw materials such as cement, sand, gravel in a certain proportion to prepare it into concrete. Existing concrete mixers have no anti-blocking mechanism. After long-term operation, the solidification of concrete or other reasons may cause the discharge port to be blocked. If there is no anti-blocking mechanism to deal with it, the blockage will cause the equipment to stop and affect production efficiency. When blocked, manual cleaning is required. Operators clean directly with hands or tools, which consumes time and energy and poses safety hazards.
