[0002] A chain conveyor is a type of conveying equipment that uses chains as transmission and load-bearing elements. It is widely used in industrial production and material handling. Its main structure includes chains, sprockets, conveyor belts and brackets. The chain rotates through the sprockets to move the material along the conveying path. It is suitable for heavy loads and high temperature environments. Chain conveyors have the advantages of strong load-bearing capacity, wear resistance and smooth operation. They are often used in coal mining, metallurgy, chemical industry and food industries. According to different needs, chain conveyors can be designed into horizontal, inclined or vertical conveying methods to flexibly adapt to the material conveying needs of various production lines.

[0003] The chain is a load-bearing mechanical component that is easily damaged and consumed. During operation, in order to ensure the smooth movement of each moving part and reduce wear, the chain usually needs to be lubricated.
