The operating components in the middle section of the conveyor (except for the head and tail) are supported and dragged on a series of gantry supports through the track, with each support generally spaced 3000mm apart. The bottom support feet are welded to the embedded steel plate of the foundation, and the upper and middle parts of the support are equipped with towing frames. The track is welded to this towing frame. The joints of each section of steel rail are connected with fishplates and bolts, leaving a gap of 6mm at each joint. An upper guard rail is installed at the arc section where the conveyor direction is changed to prevent the running parts from floating on the track when the chain tension is too high. In order to ensure the safety of on-site inspection workers, safety nets are installed on both sides of the entire conveyor direction, and the safety nets are suspended on brackets.

In summary, the working process of this conveyor is as follows: a sufficiently long running component wraps around the head, the tail sprocket is docked to form a closed chain, the chain at the bottom of the material groove meshes with the head and tail sprockets, and the rollers on the side of the material groove are respectively supported on the upper and lower tracks in the middle back and forth section. When the power of the electric motor is transmitted from the gearbox to the head wheel shaft, the driving sprocket drives the running component to perform cyclic motion, The roller supports the chain and the material groove to roll along the track, so that the material loaded in the groove is transported to the head and unloaded with the operation of the moving parts. Materials are usually added from the tail, but can also be added freely in the middle of the conveyor according to process requirements.
