The outer surface of the moving plate 12 is movably connected to the top of the base plate 1, the bottom of the mounting plate 3 and the inner surface of the mounting frame 2 respectively. The rotation of the rotating rod 8 will cause the moving plate 12 to move horizontally left and right.

[0031] When the driving motor 6 starts to run, the rotating shaft 7 will drive the rotating rod 8 to rotate, and the round rod 9 will start to rotate, so that the sleeve rod 10 will drive the connecting rod 11 to move horizontally left and right, so that the two moving plates 12 will move horizontally away from each other under the limiting action of the mounting plate 3 and the mounting frame 2.

[0033] When the first motor 15 starts to run, the rotating rod 16 drives the driving wheel 17 to rotate.

[0034] Among them, a connecting plate 18 is movably connected to the right side of the top of the base plate 1, and a driven wheel 19 is movably sleeved inside the top of the connecting plate 18. The driven wheel 19 is transmission-connected to the driving wheel 17 through a conveyor belt 20, and the bottom of the outer surface of the conveyor belt 20 is movably connected to the top of the mounting plate 3.

[0035] When the driving wheel 17 starts to rotate, the driving wheel 17 is driven to rotate through the conveyor belt 20 .

[0036] Among them, an inclined plate 21 is fixedly connected to the right side of the top of the base plate 1, a transverse groove 23 is opened on the right side of the top of the base plate 1, and fixed blocks 22 are fixedly installed on the front and rear sides of the right side of the top of the base plate 1. The front of the fixed block 22 is fixedly connected to the third motor housing 24, and the left side of the fixed block 22 is fixedly connected to a limiting rod 29.

A second motor 25 is fixedly installed inside the third motor housing 24, and a threaded rod 26 is fixedly connected to the other end of the output shaft of the second motor 25.

[0037] When the second motor 25 starts to operate, the threaded rod 26 will rotate.

[0038] The other end of the threaded rod 26 penetrates the fixed block 22 and extends between the fixed blocks 22 and is movably connected to the front of the fixed block 22. The outer surface of the threaded rod 26 is threadedly connected with a movable plate 27, and the outer surface of the movable plate 27 is movably connected to the inside of the transverse groove 23.

[0039] When the threaded rod 26 rotates, the movable plate 27 will move forward horizontally under the limiting effect of the transverse groove 23 .

[0040] The left side of the movable plate 27 is hinged with an inclined rod 28 , and the other end of the inclined rod 28 is hinged with the right side of the connecting plate 18 .

[0041] When the moving plate 27 starts to move, it will drive the inclined rod 28 to move, and make the connecting plate 18 move horizontally to the left.

[0043] An operator can add coal to the outer surface of the conveyor belt 20 through the feed opening 33 .

[0044] The working principle and use process of this utility model:

[0045] First, coal is added to the top of the conveyor belt 20 through the feed port 33, and then the first motor 15 is started, which will cause the rotating rod 16 to drive the driving wheel 17 and the conveyor belt 20 to rotate, and drive the driven wheel 19 to rotate together. Finally, the coal will slide out of the device through the inclined plate 21. When a lot of coal powder falls from the top of the bottom plate 1, affecting the working efficiency of the conveyor belt 20, the drive motor 6 is started, so that the rotating shaft 7 drives the rotating rod 8 and the round rod 9 to rotate, and the sleeve rod 10 drives the connecting rod 11 to start moving. Finally, the two moving plates 12 move horizontally opposite to each other, completing the function of pushing the coal powder into the collecting box 4 through the rectangular groove 32, realizing the purpose of automatically cleaning the coal powder, and reducing the labor intensity of the operator.

[0046] When the conveyor belt 20 is damaged during long-term use and needs to be vulcanized, the second motor 25 is started to rotate the threaded rod 26, and the movable plate 27 is allowed to move horizontally forward under the limiting action of the transverse groove 23, and drive the inclined rod 28 to move. At this time, under the limiting action of the limiting rod 29, the connecting plate 18 drives the driven wheel 19 to move horizontally to the left, and finally the conveyor belt 20 is released from the tensioned state, making it easy for the operator to remove the conveyor belt 20 for vulcanization operation, thereby improving the efficiency of the operator's maintenance work on the conveyor belt 20.
