The longitudinal section of the support rod 302 is a triangle to prevent the falling materials from accumulating on the support rod 302. Then, under the pressure of the pressure block 301, the telescopic plates 103 will move into the telescopic grooves 106, and then the gaps between adjacent chain plate assemblies 1 will expand, and the materials stuck inside the conveyor will fall from the gaps. This design avoids the wear of the conveyor caused by the long-term sticking of materials in the conveyor, thereby extending the service life of the conveyor. In the anti-deviation assembly 2, under the drive of the adjusting motor 201, the bidirectional screw rod 203 will carry the connecting plate 204 and the anti-deviation plate 206 for symmetrical movement and adjustment, so that the materials move in the center of the chain plate assembly 1.
