At the same time, the adjustment component can be used to adjust the distance between adjacent support frames to achieve enhanced wind resistance. Increasing the gravity of the support frame can improve the stability of the entire conveying system and reduce the impact of wind on the conveyor belt. Reasonable adjustment of the support frame spacing can optimize the overall structure and further enhance the wind resistance. The conveying efficiency is improved. The stable conveying system can ensure the smooth operation of the conveyor belt and reduce conveying interruptions caused by wind.

At the same time, the wave surface has a certain elasticity, and the gravity of the material can be concentrated to pull the wave surface apart, so that the vents can be opened to generate airflow, dry the material or have other effects.

At the same time, because the inner side of the rib is set in a fish scale shape, it can effectively increase the friction between the rib and the material, making the material more stable during transportation and not easy to slip or scatter. During the ropeway transportation process, due to the large inclination angle and vibration, the reliability of material transportation is better improved, and at the same time, the material can be guided to flow more smoothly, reducing the accumulation and blockage of materials at the rib.

A plurality of rollers 14 are rotatably connected at equal intervals on both sides of the conveyor belt 2 through a connecting assembly, and the rollers 14 are rollingly arranged on the steel cables 13;

As shown in Figures 3, 4 and 5, the roller member 14 includes a cylinder 15 and a rotating shaft 16, and retaining rings 17 are fixedly sleeved on both sides of the cylinder 15, and a steel cable 13 can be embedded between the two retaining rings 17.

At the same time, the spurs 20 can be drilled into the steel cable 13, so that the burrs and the steel cable 13 have a certain effect, forming a certain adsorption effect, and increasing the stability of the roller member 14.

A plurality of limiting components 21 are evenly fixed in an annular shape on the inner side surface of the retaining ring 17. The limiting components 21 can both limit the position of the steel cable 13 and reduce the friction with the steel cable 13.

The limiting assembly 21 includes a limiting groove 22, a limiting plate 23, a wedge-shaped rubber plate 24 and an arc-shaped silicone plate 25.

At the same time, the steel cable 13 can contact the side of the limit plate 23 close to the cylinder 15, because a feather-like structure is set on the side of the limit plate 23 here, and the feather-like structure can increase the air flow between the limit plate 23 and the steel cable 13, thereby reducing friction resistance.

As shown in Figure 6, the connecting component includes two semicircular pressure plates 26 with inner arc surfaces arranged opposite to each other, and the two semicircular pressure plates 26 are fixedly connected by an arc-shaped connecting plate 27.

The limit sliding plates 31 are slidably arranged in the side plates of the support frame 4. During use, the two U-shaped limit plates 29 and the top limit rod 30 can be used to generate a stop on the upper end of the conveyor belt 2. The top limiting force ensures stable operation. At the same time, because the limiting sliding plate 31 slides out of the side plate of the supporting frame 4 and is fixedly connected to the counterweight 6 by bolts, the counterweight 6 includes a counterweight block 11. The counterweight block 11 can use counterweight blocks 11 with different gravity according to actual use. The outer diameter of the limiting column is slightly smaller than the inner diameter of the limiting through hole, or a rubber ring is fixed between the limiting column and the limiting through hole. In this way, the force generated by the counterweight block 11 is transmitted through the top limiting rod 30, so that the two U-shaped limiting plates 29 can produce a tendency to press the conveyor belt 2 downward to ensure stable operation of the conveyor belt 2.
