At the same time, in order to ensure that the medicinal material powder can be discharged smoothly and thoroughly, the second motor is used to drive the gear to mesh with the external gear ring, and the bumps on the inner circumference of the external gear ring transmit power to the vibration component. The vibration plate in the vibration component is used to intermittently impact the bottom of the riser, and the impact frequency depends on the rotation speed of the second motor.

[0048] A horizontal shaft 9 is rotatably installed in the horizontal pipe 3. A plurality of spiral blades 15 and rolling discs 16 are fixedly installed on the horizontal shaft 9, and the spiral blades 15 and the rolling discs 16 are arranged at intervals on the horizontal shaft 9. One end of the horizontal shaft 9 extends to the outside of the horizontal pipe 3 and is connected to the drive shaft of the first motor 8. The other end of the horizontal shaft 9 extends into the vertical pipe 4. A square rod 17 is rotatably installed in the vertical pipe 4. An active bevel gear 121 is installed at one end of the horizontal shaft 9 located in the vertical pipe 4. A driven bevel gear 122 is slidably sleeved on the square rod 17, and the active bevel gear 121 is in meshing transmission with the driven bevel gear 122;

[0049] The bottom of the vertical pipe 4 is a hemispherical cavity structure, and a sieve hole is opened at its bottom. The upper end of the square rod 17 is rotatably installed with the telescopic end of the electric push rod 18 through a rotating collar 19. The housing of the electric push rod 18 is fixed at the top of the vertical pipe 4. The lower end of the square rod 17 extends into the hemispherical cavity of the vertical pipe 4 and is fixed with a crushing sphere 21. The inside of the crushing sphere 21 is a cavity structure, and a telescopic crushing assembly 22 extending to the outside of the crushing sphere 21 is installed on the inner wall of the crushing sphere 21;

[0050] An external gear ring 24 is rotatably installed on the outside of the discharge pipe 6. A plurality of convex blocks 28 are fixed on the inner circumference of the external gear ring 24. A second motor 23 is installed on the outside of the discharge pipe 26. A gear 25 is installed on the drive shaft of the second motor 23, and the gear 25 is in meshing transmission with the external gear ring 24;

[0051] A plurality of oscillation assemblies 26 extending to the outside of the discharge pipe 26 are installed on the inside of the discharge pipe 26. The oscillation assemblies 26 are in separable extrusion contact with the convex blocks 28, and the tops of the oscillation assemblies 26 are in separable contact with the outside of the bottom of the vertical pipe 4.

[0052] The medicinal materials entering the horizontal pipe 3 are conveyed by the spiral blades 15 installed on the horizontal shaft 9. The medicinal materials are gradually conveyed into the vertical pipe 4, and are also subjected to preliminary rolling and crushing treatment by the rolling discs 16 during the conveying process, which is not only convenient for the conveyance of the medicinal materials but also facilitates subsequent efficient crushing treatment.

[0053] Furthermore, the driven bevel gear 122 is rotatably installed with a support arm 20. The support arm 20 is fixedly installed inside the vertical pipe 4. A square hole is opened in the center of the driven bevel gear 122, and the square rod 17 passes through the square hole and is slidably installed with the driven bevel gear 122.

[0054] Furthermore, a first bevel gear 11 is installed at one end of the horizontal shaft 9 close to the driving shaft of the first motor 8, and a vertical shaft 10 is rotated between the outer side of the feeding hopper 5 and the outer side of the horizontal tube 3;

[0055] The crushing assembly includes a crushing shaft 13 rotatably mounted inside the feeding hopper 5, a plurality of crushing blades are radially mounted on the surface of the crushing shaft 13, the upper end of the crushing shaft 13 and the upper end of the vertical shaft 10 are driven by a belt drive assembly 14, a first bevel gear 11 is fixed to the lower end of the vertical shaft 10, and the first bevel gear 11 located at the end of the horizontal shaft 9 and the first bevel gear 11 located at the end of the vertical shaft 10 are meshed with each other for transmission.

[0056] When the first motor 8 is started, it drives the horizontal shaft 9 to rotate, and cooperates with the two first bevel gears 11 to control the rotation of the vertical shaft 10. The vertical shaft 10 cooperates with the belt drive assembly 14 to control the rotation of the crushing shaft 13 and the crushing blade of the crushing assembly. The crushing blade cuts and crushes the medicinal materials put into the feeding hopper 5.

[0057] Furthermore, the spiral blades 15 and the rolling disc 16 are sequentially installed on the horizontal axis 9 at intervals, and a plurality of rolling balls with different diameters are fixed on the circumferential surface of the rolling disc 16. The rolling balls with different diameters can easily crush the medicinal materials and are not easy to cause blockage of the medicinal materials.

[0058] Furthermore, each telescopic crushing assembly 22 includes a sleeve 221 fixed on the inner wall of the crushing sphere 21, and a first telescopic hole is opened at the position of the crushing sphere 21 corresponding to the sleeve 221. A crushing rod 222 is slidably installed in the sleeve 221. One end of the crushing rod 222 extends to the outside of the crushing sphere 21 through the first telescopic hole and the end is spherical. A limiting plate is fixed to the other end of the crushing rod 222, and a spring 223 is provided at the end of the limiting plate away from the crushing rod 222. The spring 223 is located inside the sleeve 221.

[0059] When the medicinal materials are transported from the horizontal pipe 3 to the vertical pipe 4, they can fall into the processing range of the telescopic crushing assembly and the crushing ball 21. When the horizontal shaft 9 is driven, the meshing transmission of the active bevel gear 121 and the driven bevel gear 122 can be used to control the rotation of the square rod 17, the crushing ball 21 and the telescopic crushing assembly 22. In this process, the electric push rod 18 is used to control the lifting of the square rod 17, so that the square rod 17, the crushing ball 21 and the telescopic crushing assembly 22 can be lifted and lowered while rotating. In this process, the medicinal materials can be squeezed and crushed by the crushing ball 21 and the telescopic crushing assembly 22 efficiently and thoroughly. It is not easy to cause blockage of medicinal materials. In addition, if Figure 2 , Figure 6 and Figure 7As shown in the figure, in this embodiment, the top of the crushing sphere 21 is frustum-shaped, which can better facilitate the falling of medicinal materials to the bottom of the crushing sphere 21, that is, into the processing range of the crushing sphere 21 and the telescopic crushing assembly 22.

[0060] Further, a limiting block 190 is rotatably arranged in the rotating collar 19, and the top end of the square rod 17 extends into the rotating collar 19 and is fixedly connected to the limiting block 190.

[0061] The structural characteristics of the above-mentioned rotating collar 19 ensure that the rotation and lifting operations of the square rod 17 do not interfere with each other, guaranteeing the normal operation of the square rod 17 and the bottom crushing sphere 21.

[0062] Further, each vibration assembly 26 includes a vibration plate 265. The middle of the vibration plate 265 is rotatably installed on a rotating shaft 266. The rotating shaft 266 is fixedly installed on the inner wall of the discharge pipe 6 through a support seat. A torsion spring 267 is sleeved on the rotating shaft 266. The two ends of the torsion spring 267 are respectively fixedly installed on the support plate and the vibration plate 265. The upper part of the vibration plate 265 is detachably in contact with the outer surface of the bottom of the riser pipe 4;

[0063] The vibration assembly 26 further includes a push rod 261 slidably installed on the discharge pipe 6. A second telescopic hole is penetrated through the side of the discharge pipe 6. One end of the push rod 261 penetrates through the second telescopic hole to the outside of the discharge pipe 6 and is fixed with a contact sphere 263. The contact sphere 263 is detachably in extrusion contact with the convex block 28;

[0064] One end of the push rod 261 extending to the outside of the discharge pipe 6 is sleeved with a second spring 262. The two ends of the second spring 262 are respectively abutted against the contact sphere 263 and the outer surface of the discharge pipe 6. The other end of the push rod 261 is located inside the discharge pipe 6 and is fixed with a push block 264. The push block 264 abuts against the lower end of the vibration plate 265.

[0065] It should be noted that when the convex block 28 is not in contact with the contact sphere 263, there is an extrusion force between the upper end of the vibration plate 265 and the bottom of the riser pipe 4 to keep them in contact.

[0066] Further, the external gear ring 24 is slidably installed with a plurality of limit sliding seats 27, and the limit sliding seats 27 are fixed on the outer surface of the discharge pipe 6;

[0067] Each limit sliding seat 27 includes two strip-shaped plates symmetrically arranged up and down, and arc-shaped chutes 270 are opened on the sides of the strip-shaped plates close to each other. The external gear ring 24 is slidably matched with the arc-shaped chutes 270.

[0068] After the medicinal materials are subjected to extrusion and crushing treatment by the crushing sphere 21 and the telescopic crushing assembly 22, they can fall from the sieve holes at the bottom of the riser 4 into the material receiving box 7 for collection. In order to ensure the efficient and thorough discharge of the medicinal material powder, a second motor 23 is provided to drive the gear 25 to mesh with the external gear ring 24, and the external gear ring 24 applies a force to the shock assembly 26 by means of the convex blocks 28 installed at the inner circumference;

[0069] As Figure 9-12 shown, specifically, when the external gear ring 24 rotates, the convex blocks 28 fixed on its inner circumference squeeze the contact sphere 263 at the end of the push rod 261, thereby pushing the push rod 261 and the push block 264 to push the lower end of the shock plate 265. At this time, the second spring 262 is compressed and the torsion spring 267 is stressed and contracts. The upper end of the shock plate 265 is temporarily separated from the bottom of the riser 4. When the convex block 28 is separated from the contact sphere 263, the second spring 262 and the torsion spring 267 are reset. At this time, it can prompt the upper end of the shock plate 265 to impact the bottom of the riser 4, thereby realizing knocking and vibration, so that the medicinal material powder in the riser 4 can be smoothly and thoroughly discharged and finally collected in the material receiving box 7. When the material receiving box 7 is rotated and removed, the medicinal materials can be taken out for research and use.
