[0002] Belt conveyors are widely used in the metallurgical, mining, and power industries for conveying various materials. A large-inclination belt conveyor can only use a corrugated baffle belt to convey materials due to its large inclination angle, resulting in a large amount of residual material on the return belt surface that cannot all fall into the discharge hopper or auxiliary chute. Vibration during the operation of the belt conveyor causes the residual material on the return belt surface to scatter on the ground around the belt conveyor, which not only pollutes the working environment and increases the labor intensity of the workers on the post, but also causes waste of the material. Therefore, it is necessary to design a device capable of preventing the residual material on the return belt surface of a large-inclination belt conveyor from scattering randomly. SUMMARY

The tensioning drum is installed on the tensioning hanger and located below the return belt surface of the large-inclination belt conveyor. The sealing conveyor belt passes through the tensioning drum, the redirection drum, and the tail drum to form a ring-shaped conveyor belt. The belt surface on the sealing conveyor belt is tightly attached to the return belt surface of the baffle belt of the large-inclination belt conveyor to form a sealed space.

[0006] In the above-mentioned device for preventing the residual material on the return belt surface of a large-inclination belt conveyor from falling, the tensioning drum is installed on the tensioning hanger through a spiral tensioning device.

[0007] In the above-mentioned device for preventing the residual material on the return belt surface of a large-inclination belt conveyor from falling, the redirection drum includes an upper redirection drum and a lower redirection drum. The upper redirection drum is located above the tail of the large-inclination belt conveyor. The lower redirection drum is located below the tail of the large-inclination belt conveyor.

[0008] In the above-mentioned device for preventing the residual material on the return belt surface of a large-inclination belt conveyor from falling, the lower belt surface of the sealing conveyor belt is supported by a plurality of lower supporting rollers arranged at equal intervals.

[0009] The utility model discloses a sealing conveyor belt is arranged in the lower part of return belt surface of large inclination angle belt conveyor, utilizes sealing conveyor belt to prevent residual material in return belt surface from scattering on the ground around the belt conveyor, not only can effectively improve the working environment, reduce the labor intensity of post worker, but also reduce the waste of material.
