A bolt 25 is threadedly connected to the inner surface of the sleeve 15 to facilitate the overall positioning and fixing of the sleeve 15. The outer surface of the bolt 25 is threadedly connected to the supply pipe 1 to facilitate the positioning and fixing of the sleeve 15. A limiting groove 24 is provided on the upper surface of the fixing plate 2. The inner surface of the limiting groove 24 is adapted to the L-shaped fixing plate 5 to limit the movement of the L-shaped fixing plate. The outer surface of the lead screw 4 is rotatably connected to the fixing plate 2. The outer surface of the rotating shaft 7 is rotatably connected to the L-shaped fixing plate 5. The inner surface of the sliding groove 9 is adapted to the connecting frame 11 to limit the movement of the connecting frame 11. The outer surface of the supply pipe 1 is slidably connected to the sleeve 15. The drive motor 3 and the stepper motor 6 are both electrically connected to an external power source.
[0028] The outer surface of the supply pipe 1 is provided with a discharge hole 16, the outer surface of the sleeve 15 is provided with a through hole 17, the outer surface of the sleeve 15 is fixedly connected to a hopper 18, the inner surface of the hopper 18 is slidably connected to a drawer box 19, the inside of the drawer box 19 is provided with a sampling chamber 20, the inner surface of the sampling chamber 20 is fixedly connected to a discharge pipe 21, which facilitates the discharge of samples from the corresponding sampling chamber 20.

[0029] Working principle: When it is necessary to sample the pulp supplied inside the supply pipe 1, first loosen and remove bolt 25 to release the restriction on the sleeve 15. Then, start the stepper motor 6 to drive the rotating shaft 7 to rotate the turntable 8 one revolution. Then, with the cooperation of the fixed column 12, connecting strip 13, and connecting rod 14, the sleeve 15 moves to the right along the supply pipe 1. Finally, it is reset. When the through hole 17 on the sleeve 15 overlaps with the discharge hole 16 on the supply pipe 1, the pulp inside the supply pipe 1 will pass through the overlapping hole. The stacked pulp falls into the drawer 19 inside the hopper 18 and is stored in three sampling chambers 20, thereby improving the accuracy of subsequent sample testing. Furthermore, by starting the drive motor 3, the lead screw 4 drives the turntable 8 to move left and right through the L-shaped fixing plate 5, thereby adjusting the rotation radius of the connecting bar 13 around the through hole 17. When the rotation radius is adjusted, the overlap position of the discharge hole 16 and the through hole 17 will change, thereby changing the pulp sampling quantity and ensuring the representativeness of the sample.
