[0045] The present invention provides another technical solution: providing an implementation method of a high-precision crushing device, comprising the following steps:

[0046] S1. Select the medicinal materials of qualified quality and check whether they are moldy or worm-eaten. Some rhizome medicinal materials need to be preliminarily cleaned and dried first, and the drying temperature is controlled at 40-60℃;

[0047] S2, slowly add the prepared medicinal materials into the feed hopper 13, turn on the main motor 41 to control the two groups of the crushing rollers 2 to rotate in opposite directions for preliminary crushing, crush the medicinal materials into small pieces of medicine blocks, reduce the difficulty of subsequent crushing, and start the motor A52 and the motor C73 at the same time after the medicine blocks fall into the inner tube 5, drive the crushing blade 54 and the chassis 61 to rotate in the opposite direction for further crushing, and drive the bevel gear A45 to rotate through the belt B44 during the crushing process, thereby driving the bevel gear B451 and the reciprocating screw 46 to rotate, and use the magnetic attraction effect of the magnetic ring A49 and the iron sleeve ring 63 to allow the qualified powder to be discharged through the annular filter plate 62 during the crushing process, and collect the powder in the collection frame 16 under the blocking effect of the guide ring 55 to avoid excessive crushing that affects the crushing accuracy and affects the crushing speed of other medicinal materials;

[0048] S3. During the crushing process, the connecting short rod 31 rotates and cooperates with the belt A33 to drive the connecting long rod 32 to rotate. During the crushing process of the crushing roller 2 and the crushing blade 54, the rubber eccentric roller 34 rotates and continuously hits the outer wall of the inner box 15 to shake off the attached powder to prevent adhesion and reduce residue.

[0049] Specifically, during the crushing process, the main motor 41 is turned on to drive the rotating shaft B42 and the crushing roller 2 to rotate, and the medicinal materials are added into the hopper 13 and initially crushed by the crushing roller 2 to become small pieces of medicinal materials. Then, the motor A52 is turned on to drive the rotating shaft A53 to rotate, and the crushing blade 54 is rotated for further high-precision crushing. At the same time, the motor C73 is turned on, and the motor C73 cooperates with the rotating shaft C74 to realize the rotation of the chassis 61. During the rotation of the rotating shaft B42, the rotating rod 43 is driven to rotate by the belt B44 transmission, and the horizontal rotation force is converted into the vertical rotation of the reciprocating screw rod 46 by the bevel gear A45 and the bevel gear B451. Under the limiting action of the limiting frame 47, the connecting block 48 is used to drive the magnetic ring A49 sleeved on the outside of the inner cylinder 5 to rise and fall, and the iron sleeve ring 63 is driven to do reciprocating lifting motion under the action of magnetic attraction. When the iron sleeve ring 63 moves downward, it drives the annular filter plate 62 to move downward, and the filter screen end of the annular filter plate 62 leaks out, and the crushing compound is rotated by the centrifugal force through the rotation of the chassis 61. The powder in the grid is thrown out through the filter screen in time. Under the blocking effect of the guide ring 55, the powder falls into the collection frame 16 to be collected. When the iron ring 63 moves upward, it drives the push rod 651 and the compression plate 652 to move upward, thereby squeezing the gas inside the gas storage pipe 653, squeezing the gas into the air ring 58 through the one-way pressure valve B655 and the air guide groove 6551, and finally discharged through the jet groove inclined 656 and the one-way pressure valve C6561, reaching the annular filter plate. When the filter plate 62 moves upward, the attached powder is blown away. The air supply pipe 6541 and the one-way pressure valve A654 are used to balance the internal air pressure of the air storage pipe 653. The air baffle 658 guides the air blowing to ensure that the air flow is stably blown to the filter screen on the annular filter plate 62 during the air blowing, and guides the blown powder at the same time. The brush 657 scrapes off the powder during the upward movement of the annular filter plate 62, and finally achieves the purpose of timely discharging the crushed powder and preventing the powder from adhering and agglomerating.

[0050] During the up and down reciprocating movement of the magnetic ring A49, the magnetic ring A49 is used to drive the magnetic ring B inside the rubber scraper ring 511 to move up and down, completing the wall scraping work while driving. During the rotation of the crushing roller 2, the connecting short rod 31 is driven to rotate. Under the limiting action of the limiting ring A311 and the limiting ring group B321, the belt A33 is used to drive the connecting long rod 32 to rotate, and then the rubber eccentric roller 34 is driven to rotate. The rubber eccentric roller 34 is used to knock on the outer wall of the inner box 15 to shake off the medicinal materials that may be attached to the inner wall of the inner box 15, thereby achieving the purpose of preventing the adhesion of medicinal powder.
