A lifting slide plate 503 is screwed onto rod 502. The left side of the lifting slide plate 503 is connected to the connecting plate 6. The fixing mechanism 7 includes a fixing plate 701. A fixing groove 702 is provided on the right side of the fixing plate 701. A fixing motor 703 is provided at the top of the inner cavity of the fixing groove 702. A fixing screw 704 is provided at the bottom power output end of the fixing motor 703. The fixing screw 704 is rotatably connected in the fixing groove 702. A fixing slide plate 705 is screwed onto the fixing screw 704. A sampling cylinder 8 is located at the bottom right side of the fixing plate 701. A sampling head 801 is connected to the bottom of the sampling cylinder 8. A piston plate 802 is slidably connected to the inner cavity of the sampling cylinder 8. A support rod 803 is provided at the top of the piston plate 802. A support plate 804 is provided at the top of the support rod 803. The left side of the support plate 804 is connected to the fixing slide plate 705.

[0026] The controller 2 is connected to the drive motor 301, the lifting motor 501, and the fixed motor 703. The drive motor 301 can rotate in both directions. When the drive motor 301 is started, it drives the drive rod 302 to rotate in the forward direction. The drive rod 302 drives the drive gear 303 to rotate, which in turn drives the mounting gear 402 to rotate. The mounting gear 402 drives the mounting rod 401 to rotate, which in turn drives the mounting plate 4 to rotate. The mounting plate 4 then drives the connecting plate 6 to rotate, and the connecting plate 6, through the fixed plate 701, drives the sampling cylinder 8 to rotate. After the sampling cylinder 8 is moved directly above the inlet pipe 9, the drive motor 301 is turned off.

[0027] The lifting motor 501 can rotate in both directions. Starting the lifting motor 501 drives the lifting screw 502 to rotate in the forward direction. The lifting screw 502 then drives the lifting slide plate 503 to rotate. The lifting slide plate 503 is a square plate, and the lifting groove 403 is adapted to it. The lifting slide plate 503 is slidably connected within the lifting groove 403. Under the limit of the lifting groove 403, the lifting slide plate 503 moves downward, causing the connecting plate 6 to move downward. The connecting plate 6 then causes the fixing plate 701 to move downward, which in turn causes the sampling cylinder 8 to move downward. After the sampling cylinder 8 extends into the pulp inside the box 1 through the inlet pipe 9, the lifting motor 501 is turned off.

[0028] The fixed motor 703 can rotate in both directions. Starting the fixed motor 703 drives the fixed lead screw 704 to rotate in the forward direction. The fixed lead screw 704 then drives the fixed sliding plate 705 to rotate. The fixed sliding plate 705 is a square plate, and the fixed groove 702 is adapted to it. The fixed sliding plate 705 is slidably connected within the fixed groove 702. Under the limitation of the fixed groove 702, the fixed sliding plate 705 moves upward, driving the support plate 804 to move upward. The support plate 804 then drives the support rod 803 to move upward, which in turn drives the piston plate 802 to move upward. After the pulp is drawn into the sampling cylinder 8 through the sampling head 801, the fixed motor 703 is turned off.

[0029] At this time, control the lifting motor 501 to rotate in the reverse direction to drive the connecting plate 6 to move upward, and move the sampling cylinder 8 out of the box 1. Control the drive motor 301 to rotate in the reverse direction to drive the mounting plate 4 to rotate in the reverse direction, and move the sampling cylinder 8 directly above the bottom plate 3. After placing the measuring cup directly below the sampling cylinder 8, control the fixing motor 703 to rotate in the reverse direction to drive the piston plate 802 to move downward, and discharge the pulp extracted in the sampling cylinder 8 into the measuring cup, thus completing the pulp sampling.
