The outer end of the adjustment column 15 is fitted with a locking pin through a sleeve. The arc-shaped protruding edges 16 are evenly distributed with… Several perforations that cooperate with the locking pin structure allow the operator to precisely adjust the position of the adjusting baffle 9 by moving the adjusting pin 15 within the arc-shaped adjusting port 14. This controls the alignment between the small opening 10 and the microporous channel 7, thereby regulating the release rate and amount of particulate matter.

Next, the servo motor 5 is started, and its output shaft drives the distribution disk 6 to start rotating and shaking back and forth in an orderly manner, so that the particulate matter is evenly distributed in the microporous channel 7 of the distribution disk 6 under the action of centrifugal force. During this process, the arc-shaped guide blocks 12 on both sides of the distribution disk 6 slide along the arc-shaped guide groove in the guide seat 13, ensuring the stability and accuracy of the distribution disk 6 during the movement. If it is necessary to adjust the height of the distribution disk 6 to adapt to different experimental conditions, the height can be adjusted by loosening the tightening bolt on the outside of the connecting sleeve 3 and adjusting the position of the support bracket 4. After completing the above steps, the particulate matter is released through the microporous channel 7 at the set speed and amount, thus completing a series of operations.
