The top surface of each moving plate 51 is rotatably connected to a first rotating column 54, the top of each first rotating column 54 is fixedly connected to a rotating plate 55, and the bottom surface of each rotating plate 55 is fixedly connected to a push plate 56. The outer wall of each first rotating column 54 is fixedly connected to a connecting ring 57, and the outer wall of each connecting ring 57 is fixedly connected to a positioning rod 58. The top surface of each moving plate 51 is close to the fixed The position of the positioning rod 58 is fixedly connected to the limiting block 59, and the limiting block 59 is set on the side away from the first fixed plate 21. The side of each movable plate 51 away from the limiting block 59 is fixedly connected to the first fixed rod 510, and the side of each rotating plate 55 close to the limiting block 59 is fixedly connected to the second fixed rod 512. The side of each second fixed rod 512 close to the first fixed rod 510 is fixedly connected to the spring 511, and the end of the spring 511 away from the second fixed rod 512 is fixedly connected to the close first fixed rod 510.

[0024] In the embodiment, when the coal fuel contacts the pushing plates 56 during conveying, the pushing plates 56 on both sides drive the rotating plates 55 to rotate, so that the pushing plates 56 do not block the coal fuel, and when the rotating plates 55 rotate, the springs 511 change from the relaxed state to the stretched state, so that the pushing plates 56 can automatically reset, so that the pushing plates 56 can buffer the coal fuel to some extent, and reduce the probability of blockage caused by the coal fuel falling too fast.

[0025] Further, As shown in Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 ; In combination with the above: In order to improve the cleaning effect of the coal fuel blockage, in an optional embodiment, the top surface of each rotating plate 55 is rotatably connected with a second rotating column 513 near the first rotating column 54, the top end of the second rotating column 513 is rotatably connected with a connecting plate 514, the bottom surface of any side of the connecting plate 514 is fixedly connected with a second connecting rod 515, the two sides of the side plate 2 near the second connecting rod 515 are fixedly connected with a second mounting plate 517, the second mounting plate 517 is rotatably connected with a second threaded rod 519, the second threaded rod 519 is threadedly connected with a second threaded ring 516, the second threaded ring 516 is fixedly connected with the second connecting rod 515, a second motor 518 is installed on the second mounting plate 517 away from the second connecting rod 515, the output shaft of the second motor 518 penetrates through the proximal second mounting plate 517 and is fixedly connected with the second threaded rod 519, and the top surface of each side plate 2 is provided with a second sliding groove 53, and the bottom surface of each moving plate 51 is fixedly connected with a second sliding block 52, the second sliding block 52 is arranged in the proximal second sliding groove 53, and the moving plate 51 is slidably connected with the side plate 2 through the second sliding block 52 and the second sliding groove 53.

[0026] In the embodiment, when the coal fuel appears blockage, the second motor 518 can be started to drive the second threaded rod 519 to rotate, drive the second threaded ring 516 to move, drive the connecting plate 514 to move, and drive the pushing plates 56 on both sides to move together. Under the action of the limiting block 59, the pushing plate 56 will be limited when moving towards the bottom and will not rotate, so that the pushing plate 56 pushes the blocked coal fuel, quickly cleans the coal fuel blockage in cooperation with the feeding structure 4, and ensures the stability of the coal fuel conveying.

[0027] Further, As shown in Figures 1 to 2 ; In combination with the above: In order to facilitate the receiving of coal fuel, in an optional embodiment, the top end of the side plate 2 is fixedly connected with a feeding hopper 23, and the bottom surface of the discharging plate 1 is fixedly connected with a support frame 11.

[0028] In this embodiment: the support frame 11 can support the device, and the feeding hopper 23 can facilitate the feeding of coal fuel into the device.

[0029] The working principle and use process of the present application: coal fuel will fall through the feeding hopper 23 onto the feeding roller 3 between the side plates 2 during conveying, and quickly slide to the bottom end of the discharging plate 1 under the action of the feeding roller 3, completing the conveying of the coal fuel. When a large amount of coal fuel is dropped at one time, the coal fuel may accumulate in one place, causing the coal fuel to be blocked between the side plates 2, preventing the feeding roller 3 from rotating. At this time, the first motor 411 can be started to drive the first threaded rod 412 to rotate, causing the first threaded ring 413 to drive the moving rod 42 to move in the guide opening 41, causing the moving rod 42 to drive the rack 45 to move on the side plate 2, causing the rack 45 to continuously mesh with the plurality of gears 43 during movement, causing the gears 43 to drive the feeding roller 3 to rotate, thereby causing the feeding roller 3 to move the accumulated coal fuel, allowing the coal fuel to be normally conveyed. Since there is a gap between the feeding rollers 3, coal ash from the coal fuel may fall through the gap onto the discharging plate 1, possibly forming an accumulation. When the moving rod 42 moves, the sleeve 48 drives the slag pushing shovel 49 to move, causing the slag pushing shovel 49 to push the coal ash to the bottom end of the discharging plate 1, preventing the accumulation of coal ash and ensuring the stability of the coal fuel conveying. When the coal fuel comes into contact with the pushing plate 56 during conveying, the two pushing plates 56 drive the rotating plate 55 to rotate, preventing the pushing plate 56 from blocking the coal fuel. When the rotating plate 55 rotates, the spring 511 changes from a relaxed state to a stretched state, allowing the pushing plate 56 to automatically reset, causing the pushing plate 56 to buffer the coal fuel, reducing the probability of blockage due to the coal fuel falling too quickly. When the coal fuel is blocked, the second motor 518 can be started to drive the second threaded rod 519 to rotate, causing the second threaded ring 516 to drive the connecting plate 514 to move, causing the connecting plate 514 to drive the two pushing plates 56 to move together. Under the action of the limiting block 59, the pushing plate 56 will be limited from rotating when moving towards the bottom, thereby causing the pushing plate 56 to push the blocked coal fuel. In cooperation with the feeding structure 4, the coal fuel blockage is quickly cleaned, ensuring the stability of the coal fuel conveying.

[0030] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent ones.
