Its main structures include chains, sprockets, conveyor belts and brackets. The chain rotates through the sprocket 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, food and other industries. According to different needs, chain conveyors can be designed as horizontal, inclined or vertical conveying methods to flexibly adapt to the material conveying needs of various production lines.

The rotation of the two bevel gears E will drive the transmission shafts B on the arc-shaped plates A and B to rotate. The rotation of the two transmission shafts B will drive the bevel gear C to rotate through the bevel gears D on the top. The rotation of the bevel gear C will drive the two rotating pins on the arc-shaped plates A and B to rotate through the two sprockets B and the chain B. The rotation of the two rotating pins will drive the transmission pinion to rotate.

[0015] The rotation of the two transmission pinions on the arc-shaped plate A and the arc-shaped plate B will rotate the arc-shaped rack, so that the arc-shaped rotating bars on the arc-shaped plate A and the arc-shaped plate B will rotate in a circle inside the small pulley.
