Apron Plate Feeder is composed of special reducer, head device, frame, running mechanism, tail tensioning device and other components. In the moving parts, the conveying trough is connected with the traction chain and the bearing mechanism respectively. The motor and the special reducer drive the head sprocket with the cogged structure to rotate, so that the traction chain that is engaged with the sprocket can drive the conveying trough with materials to move forward. The carrier wheel of the Apron Plate Feeder holds the conveying trough and bears the weight of materials and running components. The bearing mechanism - traction chain runs on the carrier wheel. The weight is borne by the frame with certain strength and rigidity, and transferred to the base material through the frame. The material is pushed into the conveying trough from the storage bin above the tail, and then discharged from the chute of the head cover when the conveying trough moves forward.
