A high-strength bulldozer die-forged chain with a pitch of 228.6mm (9 inches) is used as the traction part. Two chains are connected to form a closed loop by passing through a pair of driving sprockets installed at the head of the machine body and a pair of tensioning wheels at the tail of the machine body. Each link of the two rows of chains is equipped with overlapping, heavy-duty conveying troughs to form a continuous conveying line capable of carrying materials.

Its dead weight and the weight of the materials are supported by multiple rows of supporting rollers, chain support wheels, and slideway beams installed on the machine body. The transmission system is connected to the reducer through an AC variable frequency speed regulating motor, and then the expansion sleeve is directly connected to the drive device to drive the carrying mechanism to run at a low speed.

The materials unloaded from the tail silo are transported to the front of the machine body along the conveying line for discharge, to achieve the purpose of continuous and uniform feeding to the working machinery below.
