The plate chain drives the head wheel, the red hub is made of cast iron, with weight-reducing holes to reduce its own weight; the black gear ring is a quenched wear-resistant steel, which can be replaced separately after wear, reducing maintenance costs. The tooth profile is precisely adapted to the plate-type lifting chain to ensure uniform force on both sides, effectively preventing eccentric wear and tooth jumping of the chain, and improving transmission stability.As the driving wheel, it is driven by the motor reducer, which transmits power through the meshing of the gear ring and the plate lifting chain, and the traction hopper completes the vertical lifting and unloading action of the material.
