Then, the air is guided by the collecting plate 25 and blown evenly to the bottom of the screening plate 16, and the medicinal material particles remaining at the sieve holes of the screening plate 16 are blown up and crushed multiple times. A grinding bin 27 is fixedly connected to the side of the discharge bin 5 away from the transfer bin 1, a motor 3 29 is arranged inside the grinding bin 27, a grinding roller 30 is fixedly connected to the top of the inner wall of the grinding bin 27, a support plate 31 is fixedly connected to the top of the side of the grinding roller 30, a side of the motor 3 29 is rotatably connected to one side of the support plate 31, a support column 28 is fixedly connected to the side of the motor 3 29, a side of the support column 28 away from the motor 3 29 is fixedly connected to the inner wall of the grinding bin 27, the grinding roller 30 grinds the medicinal material particles to make the medicinal material crushed more thoroughly, and the medicinal material powder slides and is discharged through the gap between the bottom of the grinding roller 30 and the inner wall of the grinding bin 27; The grinding chamber 27 is fixedly connected to a sealing chamber 32 on one side away from the discharge chamber 5. A through groove is provided on one side of the bottom of the sealing chamber 32, and a collecting chamber 33 is slidably connected to the inner wall of the through groove.

The bottom of the transfer bin 1 is fixedly connected to the base 26 , the bottom of the base 26 is fixedly connected to the bottom plate 34 , the bottom of the sealing bin 32 is fixedly connected to the top of the bottom plate 34 , and the bottom of the collecting bin 33 is slidably connected to the top of the bottom plate 34 .

[0019] Working principle: the medicinal materials are put into the top bin 22 through the feeding baffle 23, and the medicinal materials fall onto the screening plate 16 in the crushing bin 15. The collecting plate 24 is located at the bottom corner of the top bin 22 to prevent the medicinal materials from getting stuck. The motor 2 17 drives the center seat 19 and the blade 21 to rotate quickly to crush the medicinal materials. The fully crushed small particles of the medicinal materials fall onto the inclined partition 2 through the sieve holes of the screening plate 16. The larger medicinal material fragments stay on the screening plate 16 and are repeatedly cut by the blade 21 until they can pass through the sieve holes of the screening plate 16. The air pump 7 sucks out the air in the filter bin 9 through the connecting pipe 8, and the air in the discharge bin 5 is filtered by the filter bin 9 and then discharged into the air pump 7. The discharge bin 5 is in a negative pressure state, and the sealing bin 32 and the collecting bin 33 are in a sealed state, so that the air in the discharge bin 5 flows from the external air into the transfer bin 1 through the feeding baffle 23, and then enters the discharge after being blocked by the partition 2. In the bin 5, the air can help the medicinal material particles slide along the surface of the partition 2 and the inner wall of the discharge bin 5 to the grinding roller 30 during the flow process. The filter bin 9 is located in the upper area of ​​the discharge bin 5 to prevent the medicinal material particles from being sucked out. The motor 3 29 drives the grinding roller 30 to rotate slowly to grind the medicinal material particles at the bottom of the grinding roller 30 and the gap between the inner wall of the grinding bin 27 to turn the medicinal material into powder. Finally, the medicinal material powder passes through the sealing bin 32 and falls into the collecting bin 33 for collection. The air pump 7 discharges the air into the bottom area of ​​the transfer bin 1 through the hose 10. At this time, the partition 2 is in an inclined state to seal the top of the transfer bin 1, so that the air in the bottom area of ​​the transfer bin 1 pushes the baffle 13 open and is discharged. The arc surface at the bottom of the partition 2 cooperates with the inclined surface at the bottom of the transfer bin 1 to reduce the residual medicinal material particles. At this stage, the partition 2 plays a role in guiding the transmission of medicinal material particles and guiding the air flow to help the medicinal material particles move. After a period of time, stop adding medicinal materials, insert the filter plate into the top bin 22 to block the medicinal material feed port, wait for the medicinal material particles to continue to move for a period of time, so that the medicinal material particles on the partition 2 are emptied, turn on the motor 3 to drive the partition 2 to rotate to a vertical state, and the air pump 7 increases the operating power to accelerate the air flow rate, the partition 2 blocks the opening of the transfer bin 1, and a certain gap is left between the arc surface at the bottom of the partition 2 and the bottom of the opening. At this time, the openings on both sides of the discharge bin 5 cannot take in air, and the outside air pushes the baffle 2 14 to enter the discharge bin 5. The baffle 2 14 is in an inclined state, and the air is discharged into the bottom area of ​​the transfer bin 1 through the hose 10. It is blown upward by the guide plate 11, dispersed by the diverter plate 12, and then evenly blown to the bottom of the screening plate 16 by the collecting plate 25. At this time, the torsion spring of the baffle 13 is reset to block the exhaust port of the transfer bin 1, most of the air is blown to the screening plate 16, and a small amount of air The particles of medicinal material remaining on the inner wall of the discharge bin 5 are blown toward the grinding roller 30 by the inclined baffle 2 14 to guide the air, and the air blowing upward in the transfer bin 1 blows out the particles of medicinal material remaining in the sieve holes of the screening plate 16, and then they are crushed to avoid the sieve holes of the screening plate 16 being blocked and reducing the passing efficiency. At this stage, the partition 2 plays a role in changing the direction of air flow, solving the problem of the sieve holes of the screening plate 16 being blocked and reducing the problem of residual medicinal material in the discharge bin 5. Then the partition 2 is reset to an inclined state, and finally the collecting bin 33 is opened to take out the medicinal material powder. The collecting bin 33 is reset to start the next round of medicinal material crushing. The reduction of medicinal material residue and the solution of blockage problems are both solved by air flow. Air flow plays a variety of roles to reduce equipment and energy consumption, and is more energy-efficient.
