The raw material is poured into the opening above the hopper 5, and the raw material will slide into the cavity 9 of the machine body 2 along the side wall of the hopper 5, and the driving motor 4 drives the crushing assembly 3 to crush the raw material. A discharge port for discharging powdery particles is provided on the machine body 2, and the discharge port is connected to the cavity 9. The collecting box 6 is arranged at a distance on one side of the machine body 2, and the collecting box 6 is connected to the discharge port of the machine body 2 through a connecting pipe 11. In this embodiment, the collecting box 6 is arranged in a funnel shape, and the powder particles after crushing are collected in the collecting box 6 from the discharge port through the connecting pipe 11.

[0033] At the same time, some powder particles are suspended in the gas in the collection box 6. In order to collect these powder particles, the dust box 7 is arranged at intervals on one side of the collection box 6. Several filter bags 10 for adsorbing powder particles can be removed from the dust box 7. The exhaust fan 8 is fixed on one side of the dust box 7. The exhaust fan 8 discharges the gas in the dust box 7 through the filter bag 10. The collection box 6 and the dust box 7 are connected by a connecting pipe 11. The exhaust fan 8 extracts the gas in the dust box 7. The gas with powder particles in the collection box 6 reaches the dust box 7 through the connecting pipe 11. The gas with powder particles is filtered by the filter bag 10. The powder particles remain on the surface of the filter bag 10. The filtered gas is discharged to the outside of the machine with the exhaust fan 8, which improves the recovery efficiency of the powder particles and achieves the effect that no powder particles enter the air during the crushing process.

[0034] Specifically, the crushing assembly 3 includes a knife holder 31 rotatably connected to the cavity 9 and a moving knife 32 circumferentially mounted on the knife holder 31. The knife holder 31 is set in a disc shape. The drive motor 4 is fixed to one side of the body 2. The drive motor 4 is set horizontally. The knife holder 31 is fixedly connected to the output shaft of the drive motor 4 and is set vertically. A side door 12 that can be opened and closed is rotatably connected to the side of the body 2 away from the drive motor 4. The side door 12 is used to separate or connect the cavity 9 with the outside world. A static knife 13 is set on the side surface of the side door 12 facing the cavity 9. The static knife 13 is set in a ring-shaped sawtooth shape. The movable knife 32 includes a knife handle 321 and a knife block 322. In this embodiment, six knife handles 321 and six knife blocks 322 are provided. The six knife handles 321 are evenly spaced and fixed on the knife holder 31 in the circumferential direction. The knife block 322 is fixed vertically to the knife handle 321. One end of the knife block 322 is fixedly connected to the knife handle 321, and the other end of the knife block 322 is arranged toward the stationary knife 13 and there is a certain gap between the knife block 322 and the stationary knife 13. The end of the knife block 322 close to the stationary knife 13 is provided with an inclined surface 14. The setting of the inclined surface 14 makes the knife block 322 have a sharp tip, that is, the blade of the movable knife 32.

[0035] Correspondingly, the raw material is poured into the hopper 5, and the raw material slides from the hopper 5 into the cavity 9 of the machine body 2, and the static knife 13 remains stationary. The driving motor 4 drives the knife 32 frame 31 to rotate, and the rotation of the knife frame 31 drives the moving knife 32 to rotate, and the raw material falls from the hopper 5 onto the static knife 13. The raw material collides between the moving knife 32 and the static knife 13, and is subjected to the shear force of the moving knife 32 and the static knife 13. The rotation of the moving knife 32 cooperates with the static knife 13 to crush the raw material into powder particles, forming multi-stage crushing, thereby improving the crushing efficiency of the raw material. During the rotation of the moving knife 32, an air pressure difference is formed in the cavity 9, so that the raw material is pressed toward the static knife 13, which is conducive to the crushing of the raw material. The movable blade 32 is driven to rotate by the driving motor 4, and the raw materials are poured into the hopper 5. The raw materials enter the cavity 9 and are crushed into powder particles by the cooperation of the movable blade 32 and the stationary blade 13. The powder particles are discharged from the discharge port. The continuous operation is suitable for assembly line production, and the leakage of powder particles caused by pouring out the powder particles can be effectively reduced, thereby improving the recovery efficiency of the powder particles.

[0036] Furthermore, a filter screen 15 is provided on the cavity wall of the cavity 9, and a plurality of convex strips 16 are fixed on the cavity wall of the cavity 9, and the plurality of convex strips 16 are arranged on the cavity wall of the cavity 9 at intervals in the circumferential direction. In the present embodiment, the plurality of convex strips 16 are divided into six groups, and a plurality of filter screens 15 are provided, and a filter screen 15 is provided between two adjacent groups of convex strips 16, and the filter screen 15 is engaged with the convex strips 16. The mesh size of the filter screen 15 is consistent with the size of the powder particles to be obtained, and the mesh of the filter screen 15 is connected to the discharge port. When the raw material is crushed into the mesh size, the powder particles will enter the discharge port from the filter screen 15. The raw material that has not been crushed into the mesh size continues to be crushed for the second time in the cavity 9 until it is crushed into the required powder particle size. In this way, it can be ensured that the size of the powder particles sent out from the discharge port reaches the required size, thereby improving the quality of the crushed powder particles.

[0037] Further, see Figure 3 and Figure 4 The machine body 2 is also provided with a door lock 17 for locking the side door 12. The door lock 17 includes a rotating rod 171 and a gripping block 172. One end of the rotating rod 171 is hinged to the machine body 2, and the gripping block 172 is fixedly connected to the other end of the rotating rod 171. A U-shaped block 18 is fixed to the side door 12. The U-shaped block 18 is arranged corresponding to the rotating rod 171. The side door 12 is rotated so that the side door 12 closes the cavity 9. At this time, the U-shaped block 18 is located on one side of the rotating rod 171. The rotating rod 171 is rotated so that the rotating rod 171 is clamped into the U-shaped groove 19 of the U-shaped block 18, so that the U-shaped block 18 and the rotating rod 171 are clamped and fixed, so that the side door 12 and the machine body 2 remain fixed. When the side door 12 needs to be opened, the rotating rod 171 is rotated so that the rotating rod 171 is separated from the U-shaped block 18, and the clamping fixation between the rotating rod 171 and the U-shaped block 18 is released, and the side door 12 can be opened. A handle 20 for easy grip is fixedly connected to the outer side of the side door 12. The handle 20 is provided to facilitate the operator to apply force to pull the side door 12, thereby opening and closing the side door 12 more conveniently.

[0038] In addition, the side door 12 is also provided with an air inlet 21, and the side door 12 is also fixedly connected with a ventilation net 22 by bolts, and the ventilation net 22 is located at the air inlet 21. The ventilation net 22 is used to prevent some iron objects from entering the body 2 by mistake, causing damage to the movable knife 32 and the static knife 13. The air inlet 21 is used to increase the air volume entering the body 2, reduce the temperature rise during the crushing process, and avoid the influence of the temperature increase on the quality of the powder particles. At the same time, increasing the air volume can also increase the movement of the powder particles to the discharge port, reduce the adhesion of the powder particles in the body 2, and improve the recovery efficiency of the powder particles.

[0039] The implementation principle of a Chinese medicinal material grinder in the embodiment of the present application is:

[0040] The operator first turns on the drive motor 4 and the exhaust fan 8, and the drive motor 4 drives the knife 32 frame 31 to rotate, and then pours the raw material into the hopper 5. The raw material slides from the hopper 5 to the cavity 9 of the body 2. The raw material is in powdery and granular form after being crushed by the moving knife 32 and the static knife 13. The moving knife 32 and the static knife 13 work together to crush the raw material into powdery particles, forming multi-stage crushing, which improves the crushing efficiency of the raw material. Until the particle size of the powdery particles can pass through the filter screen 15, the powdery particles fall into the collection box 6 through the connecting pipe 11, and some of the powdery particles reach the dust removal box 7 through the connecting pipe 11 with the gas in the collection box 6, and are adsorbed on the filter bag 10. It can effectively reduce the leakage of powdery particles caused by pouring out powdery particles, thereby improving the recovery efficiency of powdery particles. At the same time, the powdery particles are precipitated and collected in the collection box 6, and the powdery particles suspended in the gas are recovered in the dust removal box 7, which further improves the recovery efficiency of the powdery particles.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
