The large-inclination belt conveyor has the advantages of simple structure, reliable operation, convenient maintenance, etc. of the general belt conveyor, and has the characteristics of large-inclination conveying, compact structure, less floor area, etc., so it is an ideal equipment for conveying materials at large inclinations.

[0004] In the mining field, large-inclination belt conveyors are widely used, and they are mostly used to transport multi-edged and fragmented lumps such as coal and ore. On the one hand, during the large-inclination belt transportation process, due to the large slope, large pieces of gangue are very easy to roll down during the downward transportation process. Especially in the roadway where the machine track is integrated and used as a pedestrian passage, the flying gangue phenomenon brings serious safety hazards to the transportation of personnel and materials. Flying gangue may cause accidents such as the collision of mine cars, injury to personnel, and damage to the track. On the other hand, during the long-term operation of the belt, due to the uneven distribution of materials, belt aging and other influences, the belt may deviate. Belt deviation will not only affect the transportation efficiency, but also may cause faults such as belt wear and tear, and even lead to the shutdown of the entire transportation system. Summary of the Invention

[0007] A further improvement of the present invention is that an extension plate is connected and installed on the rear side of the horizontal section of the support frame, and a spring is elastically supported between the extension plate and the baffle.

[0008] A further improvement of the present invention is that a guide rod connected to the baffle is slidably provided on the extension plate, the guide rod is in a quarter arc shape, and the spring is sleeved on the guide rod.

[0009] A further improvement of the present invention is that a through hole is provided on the extension plate for the guide rod to pass through, and a top block for limiting is installed on the upper end of the guide rod.

[0010] A further improvement of the present invention is that the frame also includes a horizontal section connected to the lower end of its inclined section, and a first rotating drum is rotatably connected and installed at the tail of the horizontal section of the frame. A plurality of supporting rollers capable of supporting the conveyor belt are rotatably installed between the first rotating drum and the second rotating drum, and a guide groove capable of engaging and limiting the guide strip is provided on the first rotating drum.

[0011] A further improvement of the present invention is that both ends of the supporting roller are provided with a cone-shaped deviation correction wheel which is small inside and large outside.
