A method for using a solid-state drug detection and screening device as claimed in claim 6, characterized in that: The following steps are involved: 1) First, the servo motor provides power to drive the first rotating rod to rotate, and the crank shaft and the transmission rod cooperate with the connecting ears to drive the connecting sleeve to slide up and down along the limit ring in the center of the fixed ring frame, thereby realizing the vibration screening process of the sieve plate for solid drugs; 2) The vibration frequency of the screen plate can be increased by sliding the connecting sleeve and the connecting round rod and utilizing the elastic effect of the compression spring; 3) Then, the driven pulley and the driving pulley and the belt drive each other, which can drive the second rotating rod to rotate, and the worm and the worm wheel are meshed to drive the transmission shaft to rotate at the same time; 4) The ratchet sleeve and the ratchet gear cooperate with each other to drive the rotating shaft and the crushing fan to rotate, thereby realizing the crushing process of the solid medicine; 5) In addition, two cylinders provide power to push the lifting frame upward, which can separate the screening cylinder from the crushing cylinder; 6) Manually adjust the elastic buckle to release the limit on the connecting block, and then pull the three positioning clamps forward to quickly remove the crushing barrel.
