The device body 1 is moved to the sampling position, so that the sampling head 3 fixedly connected to the device body 1 moves to the sampling position. At this time, by moving the joystick 5 downward, the hydraulic chamber 4 slidably connected to the piston of the joystick 5 is cooperated, so that the pressure in the hydraulic chamber 4 increases, and the movable rod 6 slidably connected to the piston of the hydraulic chamber 4 is driven to move. The top of the movable rod 6 is fixedly connected to a spring 7, and the spring 7 is located in the internal position of the hydraulic chamber 4. The spring 7 is fixedly connected to the inner wall of the hydraulic chamber 4. The side of the movable rod 6 is fixedly connected to a gear rod 8. The side of the device body 1 is rotatably connected to a rotating shaft 9, and the front end of the rotating shaft 9 is fixedly connected to a gear 10 , the gear 10 is located at the side of the gear rod 8, and the gear 10 is in meshing state with the gear rod 8. When the movable rod 6 moves, the movable rod 6 drives the gear rod 8 fixedly connected thereto to move, and the gear rod 8 drives the gear 10 meshing therewith to rotate. A protective plate 11 is fixedly connected to the bottom of the rotating shaft 9. When the gear 10 rotates, the gear 10 drives the rotating shaft 9 fixedly connected thereto to rotate, and the rotating shaft 9 drives the protective plate 11 fixedly connected thereto to rotate, and the sampling head 3 is opened for sampling; after the sampling is completed, the joystick 5 is released, so that the joystick 5 loses its restriction, that is, the movable rod 6 loses its restriction, and moves and resets under the action of the spring 7 fixedly connected thereto, and similarly, the protective plate 11 is reset, blocking the sampling head 3 to prevent coal from adhering to the sampling head 3, thereby improving the accuracy of the detection result.

[0024] When in use, the device body 1 is moved to the sampling position, so that the sampling head 3 fixedly connected to the device body 1 moves to the sampling position. At this time, by moving the joystick 5 downward, the hydraulic chamber 4 slidably connected to the piston of the joystick 5 is cooperated, so that the pressure in the hydraulic chamber 4 increases, driving the movable rod 6 slidably connected to the piston of the hydraulic chamber 4 to move, and the movable rod 6 drives the gear rod 8 fixedly connected thereto to move, and the gear rod 8 drives the gear 10 meshing therewith to rotate, so that the gear 10 drives the rotating shaft 9 fixedly connected thereto to rotate, and the rotating shaft 9 drives the protective plate 11 fixedly connected thereto to rotate, and the sampling head 3 is opened for sampling; after the sampling is completed, the joystick 5 is released, so that the joystick 5 loses its restriction, that is, the movable rod 6 loses its restriction, and moves and resets under the action of the spring 7 fixedly connected thereto, and similarly the protective plate 11 is reset to block the sampling head 3.
