When the device is not performing crushing and sampling work, the discharge inclined pipe 12 and the circular sleeve 14 are in a horizontal state and will not collide with the coal transported above the conveyor belt below.

[0026] The crushing cylinder 10 is equipped with a crushing rod 16 inside. A first bevel gear 17 is fixedly connected to the lower surface of the crushing rod 16. A second bevel gear 18 is meshed with the outer surface of the first bevel gear 17. The first bevel gear 17 and the second bevel gear 18 work together to crush the collected coal into fine particles, which facilitates further testing of the coal.

[0027] The outer surfaces of the first bevel gear 17 and the second bevel gear 18 are provided with protective boxes 19. A circular rod 20 is fixedly connected to the right side of the second bevel gear 18. Support columns 21 are fixedly connected to the front and rear sides of the upper surfaces of the two support plates 1.

[0030] Testing the coal quality of conveyor belt coal flow requires a significant amount of manpower from operators, reducing testing efficiency and practicality.

The operator can open the electric push rod 31, and the power output end of the electric push rod 31 will drive the drive rod 32 and the push frame 33 to move back and forth. The push frame 33 pushes the sliding frame 4 forward. Then the operator starts the first drive motor 6. The rotation of the power output end of the first drive motor 6 will drive the first connecting sleeve 8, the connecting frame 9, the crushing cylinder 10, the discharge inclined pipe 12, the first material box 13, the circular sleeve 14, and the second material box 15 to rotate. When the circular sleeve 14 and the second material box 15 rotate, the second material box 15 will collect the coal transported above the conveyor belt, and then, through rotation and transport by the circular sleeve 14, the collected coal will be sent to the inside of the crushing cylinder 10 by gravity. Then, the operator restarts the second drive motor 7. The rotation of the power output end of the second drive motor 7 drives the circular rod 20 and the second bevel gear 18 to rotate. The rotation of the second bevel gear 18 then drives the first bevel gear 17 and the crushing rod 16 to rotate. The crushing rod 16 can crush the coal that enters the crushing cylinder 10, quickly crushing the collected coal into fine particles, which is convenient for later coal quality testing. Then, through the rotation of the first drive motor 6, the discharge inclined pipe 12 and the first material box 13 are rotated to the downward tilt angle, so that the crushed coal flows into the interior of the first material box 13 by gravity. Then, the operator removes the first material box 13 and places it inside the detection box 25. Then, the detection box 25 is slid under the pulse laser 28 and the spectrometer 29 for testing.
