Main shaft device: it is composed of shaft, sprocket, backup roll, expansion sleeve, bearing seat and rolling bearing. The sprocket on the shaft drives the chain to run, so as to achieve the purpose of conveying materials.

Chain unit: mainly composed of track chain, chute plate and other parts. The chain is a traction component. Chains of different specifications are selected according to the traction force. The plate is used for loading materials. It is installed on the traction chain and driven by the traction chain to achieve the purpose of conveying materials.

Supporting wheel: there are two kinds of rollers, long roller and short roller, which are mainly composed of roller, support, shaft, rolling bearing (long roller is sliding bearing), etc. The first function is to support the normal operation of the chain, and the second is to support the groove plate to prevent plastic deformation caused by material impact.

Sprocket: To support the return chain to prevent excessive deflection, affecting the normal operation of the chain.
