By setting the angle adjustment mechanism 4, the inclined bracket 2 can be driven to adjust the inclination, and the angle can be adjusted according to the actual needs of the site during the inclination process. In this way, the coal mine can be lifted and transported during transportation, so as to dock with conveyors at different heights, thereby improving the transportation flexibility of the coal mine conveyor.

[0018] See also Figure 1 , Figure 3 The angle adjustment mechanism 4 includes a base plate 401 , and two first fastening bolts 403 are threadedly connected to the outer surface of the base plate 401 .

In this embodiment, the first guide groove 402 can limit and guide the first U-shaped frame 405, so that when the hydraulic cylinder 404 pushes the first U-shaped frame 405 to move, the first U-shaped frame 405 can move stably and directional under the limitation of the first guide groove 402, and the outer surface of the first U-shaped frame 405 is fixedly connected to the first fixed shaft 409, and the outer surface of the first fixed shaft 409 is rotatably connected to the connecting plate 410.

[0020] Two symmetrical telescopic plates 406 are fixedly connected to the outer surface of the first U-shaped frame 405, and second fastening bolts 407 are installed on the outer surfaces of the two telescopic plates 406. In this embodiment, the second fastening bolts 407 can limit and fix the telescopic part of the telescopic plate 406. When the telescopic adjustment of the telescopic plate 406 is completed, the height of the telescopic plate 406 is fixed under the fixation of the second fastening bolts 407, thereby providing auxiliary support for the tilt bracket 2 to ensure the stability of the tilt transportation of the tilt bracket 2. The telescopic ends of the two telescopic plates 406 are fixedly connected with a first slider 408, and the outer surface of the first slider 408 is slidably connected to the inner wall of the slide groove 3. In this embodiment, when the first U-shaped frame 405 pushes the first fixed shaft 409 to move, the tilt bracket 2 is driven to adjust the angle under the linkage action. At this time, the movement of the first U-shaped frame 405 drives the telescopic plate 406 to move, and the first slider 408 slides on the inner wall of the slide groove 3, thereby enabling the telescopic plate 406 to be adaptively adjusted according to the included angle height of the tilt bracket 2 and the bottom plate 401.

[0021] The upper surface of the bottom plate 401 is fixedly connected to a frame 411, and two second guide grooves 412 are provided on the outer surface of the frame 411. The inner walls of the two second guide grooves 412 are slidably connected to a second U-shaped frame 413. In this embodiment, the second guide grooves 412 can limit the second U-shaped frame 413, thereby allowing the second U-shaped frame 413 to slide vertically in a directional manner, and after the second U-shaped frame 413 slides to the lowest end of the second guide grooves 412, the height of the second fixed shaft 414 is still higher than the first fixed shaft 409, so that when the first fixed shaft 409 moves, the second fixed shaft 414 always moves upward, and the outer surface of the second U-shaped frame 413 is fixedly connected to the second fixed shaft 414, and one end of the connecting plate 410 away from the outer surface of the first fixed shaft 409 is rotatably connected to the outer surface of the second fixed shaft 414. In the embodiment, the connecting plate 410 is rotatably connected to the first fixed shaft 409 and the second fixed shaft 414. At this time, the movement of the first fixed shaft 409 can push the second fixed shaft 414 to move steadily upward under the connection of the connecting plate 410. The outer surface of the second U-shaped frame 413 is fixedly connected to two pushing plates 415. The side surfaces of the two pushing plates 415 close to each other are fixedly connected to the second slider 416, and the outer surface of the second slider 416 is slidably connected to the inner wall of the slide groove 3. In the present embodiment, the second slider 416 slides inside the slide groove 3. When the second slider 416 is driven by the pushing plate 415 to adjust the angle of the tilt bracket 2, the tilt bracket 2 swings with the left end as the center of the circle. At this time, the second slider 416 slides on the inner wall of the slide groove 3, which can prevent the tilt bracket 2 from getting stuck and being unable to adjust the angle.

[0022] A transmission shaft 5 is rotatably connected to one side of the two support frames 1 that are close to each other, a first motor 6 is fixedly embedded on the outer surface of one of the support frames 1, and the output end of the first motor 6 is fixedly connected to one end of the transmission shaft 5, a first driven shaft 7 is rotatably connected to one side of the two support frames 1 that are close to each other, a second driven shaft 8 is rotatably connected to one side of the two inclined brackets 2 that are close to each other, and a tensioning mechanism 9 is provided on the outer surfaces of the two support frames 1.

[0023] See also Figure 1 , Figure 4 The tensioning mechanism 9 includes two fixed brackets 901, the outer surfaces of the two fixed brackets 901 are fixedly connected to the upper surface of the support frame 1, the outer surfaces of the two fixed brackets 901 are rotatably connected to the screw rod 902, and one end of the screw rod 902 away from the outer surface of the fixed bracket 901 is rotatably connected to the upper surface of the support frame 1, the upper surfaces of the two screw rods 902 are fixedly embedded with a second motor 903, and the output end of the second motor 903 is fixedly connected to one end of the screw rod 902.

[0024] The outer surface of the fixed bracket 901 is fixedly connected to a guide rod 904, and one end of the guide rod 904 away from the outer surface of the fixed bracket 901 is fixedly connected to the upper surface of the support frame 1, and the outer surfaces of the two screw rods 902 are threadedly connected to a moving block 905, and the inner wall of the moving block 905 is slidably connected to the outer surface of the guide rod 904. In this embodiment, the guide rod 904 can limit the moving block 905, so as to avoid self-rotation under the drive of the thread of the screw rod 902, thereby enabling the moving block 905 to stably drive the rotating shaft 906 to be raised and lowered. The inner walls of the two moving blocks 905 are rotatably connected to the rotating shaft 906, and the outer surface of the rotating shaft 906 is fixedly connected to two symmetrical tension wheels 907. In this embodiment, the rotating shaft 906 drives the tension wheels 907 on both sides to move while performing the lifting and lowering adjustment, thereby the tension of the side guard conveyor belt 11 can be adjusted according to the actual needs of the site.

[0025] The side of the two inclined brackets 2 that are close to each other is rotatably connected with a support roller 10, the outer surface of the transmission shaft 5 is installed with a sidewall conveyor belt 11, and the first driven shaft 7, the second driven shaft 8 and the support roller 10 are transmission-connected through the sidewall conveyor belt 11.

At this time, while the first U-shaped frame 405 moves, it drives the first fixed shaft 409 and the connecting plate 410 to move. At this time, after the first fixed shaft 409 moves to the left, the connecting plate 410 drives the second fixed shaft 414 to move upward. At this time, the movement of the second fixed shaft 414 drives the second U-shaped frame 413 to move, and under the limiting guidance of the second guide groove 412, the second U-shaped frame 413 is stably moved vertically. The belt of the second U-shaped frame 413 on the second fixed shaft 414 When the tilt bracket 2 moves upward, it drives the pushing plate 415 and the second slider 416 to move. At this time, the second slider 416 can push the tilt bracket 2 to adjust the angle. At this time, after the adjustment of the tilt bracket 2 is completed, when the first U-shaped frame 405 stops moving, the tilt bracket 2 drives the first slider 408 inside the slide slot 3 to move, thereby driving the telescopic plate 406 to adjust the length, and then rotating the second fastening bolts 407 on both sides to fix the length of the telescopic plate 406, thereby auxiliary support for the tilt bracket 2, ensuring the stability of the tilted transportation of the tilt bracket 2, finally, start the second motor 903 to drive the screw rod 902 to rotate, the rotation of the screw rod 902 drives the moving block 905 to move, and under the limit of the guide rod 904, the moving block 905 is stably lifted and lowered vertically, and while the moving block 905 is lifted and lowered vertically, it drives the rotating shaft 906 and the two tension wheels 907 to move, thereby adjusting the tension of the side guard conveyor belt 11.
