[0003] Belt material conveyor is widely used in various industries, including mining, metallurgy, coal, chemical industry, building materials, grain and other fields. It can transport various bulk, block and powder materials, such as coal, ore, sand and gravel, cement, fertilizer, grain, etc. In short, belt material conveyor is an efficient and convenient material conveying equipment, which can greatly improve work efficiency and reduce labor intensity, and is widely used in various industries.

[0004] However, the existing belt material conveyors also have certain shortcomings. First, the existing belt material conveyors simply use conveyor belts to transport materials. Due to the influence of factors such as vibration and wind, it is easy to cause material deviation problems.

[0005] Secondly, the conveyor belts used in existing belt material conveyors are mostly made of materials such as rubber, PVC or nylon. Due to the influence of the material's own characteristics, long-term use will cause the conveyor belt to become loose, thereby causing the conveying capacity of the conveyor belt to become weakened. Summary of the invention
