Parallel upper supporting rollers 15 for supporting the conveyor belt are arranged on the upper sides of the lower horizontal section frame 2, the inclined section frame 4 and the upper horizontal section frame 6, and parallel lower supporting rollers 16 for supporting the conveyor belt are arranged on their lower sides. Sealing structures are arranged on the outer sides of the tail frame 1, the lower horizontal section frame 2, the concave arc section frame 3, the inclined section frame 4, the convex arc section frame 5, the upper horizontal section frame 6 and the head frame 7.

[0025] Furthermore, upper retaining rollers 17 are arranged at intervals on the upper sides of the lower horizontal section frame 2, the inclined section frame 4 and the upper horizontal section frame 6, and lower retaining rollers 18 are arranged at intervals on their lower sides. The upper retaining rollers and the lower retaining rollers are respectively installed on both sides of the conveyor belt to prevent the conveyor belt from running off - track.

[0026] In this embodiment, the upper pressing pulley and the lower pressing pulley have the same structure. The upper and lower pressing pulleys are respectively in contact with the upper surfaces of the corrugated baffles on both sides of the corrugated side - wall conveyor belt. The upper pressing pulley applies a downward pressure when it rises, and the lower pressing pulley applies an upward force when it falls, ensuring that the corrugated side - wall conveyor belt passes smoothly through the concave arc section and the convex arc section frames. The lower pressing roller of the concave arc section and the upper supporting roller of the convex arc section are both long supporting rollers with different diameters. Among them, there is one lower pressing roller of the concave arc section with a larger diameter, and several upper supporting rollers of the arc section with smaller diameters.

[0027] Furthermore, the parallel upper supporting roller 15 is a long supporting roller, and its two ends are rotatably arranged above the lower horizontal section frame 2, the inclined section frame 4 and the upper horizontal section frame 6 through brackets.
