[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3 An embodiment of this utility model is provided: an air-drying and pulverizing device for processing Codonopsis pilosula, including a crushing chamber 1, a feeding mechanism 2 at the top of the crushing chamber 1, a screening mechanism 3 at the bottom of the crushing chamber 1 for screening out unqualified Codonopsis pilosula, and a conveying mechanism 5 outside the crushing chamber 1 for putting the screened Codonopsis pilosula back into the feeding mechanism 2. The raw material of Codonopsis pilosula first enters the crushing chamber 1 through the feeding mechanism 2 for crushing. The crushed Codonopsis pilosula material falls into the screening mechanism 3 at the bottom. The screening mechanism 3 screens out the unqualified Codonopsis pilosula that does not meet the particle size standard. Then, the external conveying mechanism 5 transports these unqualified Codonopsis pilosula back to the feeding mechanism 2 to realize the recycling of unqualified materials and ensure the quality of Codonopsis pilosula crushing.

[0017] Reference Figures 1-2 The feeding mechanism 2 includes a feeding bin 22, which is fixedly connected to the top of the crushing bin 1. Guide plates 6 are fixedly connected to both sides of the inner wall of the feeding bin 22. A first fan 7 is fixedly connected to the top of the feeding bin 22. A first filter screen 8 is fixedly connected to the top and bottom of the first fan 7. A second fan 9 is fixedly connected to both outer walls of the feeding bin 22. A second filter screen 10 is fixedly connected to both the front and rear sides of the second fan 9. A second feed inlet 12 is opened on the inner wall of the feeding bin 22. A feed pipe 13 is fixedly connected inside the second feed inlet 12.

[0018] The raw materials of Codonopsis pilosula in block and strip shapes are transported to the feed pipe 13 by manual labor or feeding equipment, and then smoothly enter the inner part of the discharge hopper 22 through the second feed port 12 connected to the feed pipe 13. At this time, the first fan 7 at the top of the discharge hopper 22 and the second fans 9 on both sides of the outer wall start synchronously. The first fan 7 blows air downward from the top of the discharge hopper 22, and the second fan 9 blows air into the hopper from both sides of the discharge hopper 22. The airflow of the two fans cooperates to form a stable negative pressure air duct inside the discharge hopper 22. The continuous suction generated by this air duct will act on the second feed port 12, actively sucking the raw materials of Codonopsis pilosula to be entered into the feed pipe 13, avoiding the accumulation and clumping of raw materials at the edge of the second feed port 12, and ensuring that the material enters the discharge hopper 22 at a continuous and uniform rate to prevent material interruption or congestion. Meanwhile, the guide plates 6, fixed at a certain angle on both sides of the inner wall of the feeding hopper 22, guide the material to fall towards the center of the hopper bottom along the inclined path of the guide plates 6. This prevents the material from directly impacting the areas near the second fan 9 on both sides of the feeding hopper 22 due to gravity, thereby preventing the material from adhering to and accumulating on the surface of the second filter screen 10 on the outside of the second fan 9, ensuring that the air intake efficiency of the second fan 9 is not affected. The first filter screen 8 at the top of the first fan 7 can filter dust, lint, and other impurities in the outside air, preventing impurities from entering the feeding hopper 22 with the airflow; the first filter screen 8 at the bottom of the first fan 7 can block the Codonopsis pilosula raw material from being sucked into the fan, protecting the fan components; and the second filters 10 on the front and rear sides of the second fan 9 can also filter impurities in the air entering from both sides, further preventing external impurities from mixing into the Codonopsis pilosula material, ultimately ensuring the purity of the Codonopsis pilosula raw material entering the subsequent crushing hopper 1, providing a foundation for the product quality of the subsequent crushing process.

[0019] Reference Figure 1 , Figure 4 and Figure 5 The screening mechanism 3 includes a screening chamber 23, which is fixedly connected to the bottom of the crushing chamber 1. A screen 24 is slidably connected inside the screening chamber 23. A spring 25 is fixedly connected to the top of the screen 24. The end of the spring 25 away from the screen 24 is fixedly connected to the inner wall of the screening chamber 23. A vibration motor 26 is fixedly connected to the center of the bottom of the screen 24. A first connecting pipe 27 is fixedly connected to the outside of the screening chamber 23.

[0020] The Codonopsis pilosula granules, crushed in crushing chamber 1, fall steadily under gravity and eventually settle onto the surface of screen 24 inside screening chamber 23. The vibrating motor 26 at the bottom center of screen 24 is energized, directly transmitting high-frequency vibration energy to the screen 24, causing it to vibrate up and down along the sliding trajectory of the inner wall of screening chamber 23. A spring 25, connected to the top of screen 24 and fixed to the inner wall of screening chamber 23, undergoes elastic deformation, stretching and contracting synchronously with the vibration of screen 24. This elastic restoring force helps screen 24 maintain a stable and uniform vibration frequency, preventing excessive vibration amplitude from causing material splashing or insufficient vibration from affecting screening efficiency. Under the continuous vibration of screen 24, fine particles that meet the requirements for subsequent processing will pass smoothly through the mesh of screen 24 and fall to the bottom of screening chamber 23 under gravity. However, lumpy or coarse particles that exceed the particle size limit will be intercepted by screen 24 and remain above the screen surface. As the vibration continues, these substandard materials will gradually move towards the edge of the screen 24 under the vibration thrust of the screen 24, and will eventually be discharged through the first connecting pipe 27 outside the screening chamber 23, and accurately transported to the conveying mechanism 5, in preparation for subsequent secondary crushing.

[0021] Reference Figure 1 and Figure 6 The conveying mechanism 5 includes a conveying pipe 28, which is fixedly connected to the outside of the first connecting pipe 27. A rotating shaft 29 is rotatably connected inside the conveying pipe 28, and a spiral blade 30 is fixedly connected to the outside of the rotating shaft 29. A second motor 31 is fixedly connected to the top of the conveying pipe 28, and the output end of the second motor 31 is fixedly connected to one end of the rotating shaft 29 through the conveying pipe 28. A second connecting pipe 33 is fixedly connected to the outside of the conveying pipe 28, and the end of the second connecting pipe 33 away from the conveying pipe 28 is fixedly connected to the inner wall of the first feed inlet 11.

[0022] Unqualified Codonopsis pilosula material enters the conveying pipe 28 through the first connecting pipe 27. The second motor 31 starts and drives the rotating shaft 29 to rotate. The spiral blades 30 outside the rotating shaft 29 rotate synchronously with the rotating shaft 29. Through the spiral pushing action of the spiral blades 30, the unqualified material in the conveying pipe 28 is conveyed from the bottom to the top. Finally, it is conveyed to the first feed inlet 11 through the second connecting pipe 33 and re-enters the feeding mechanism 2 for secondary crushing.

[0023] Reference Figures 1-3The crushing chamber 1 is rotatably connected to a first crushing wheel 14 and a second crushing wheel 15. A first gear 16 is fixedly connected to one end of the first crushing wheel 14 and a second gear 17 is fixedly connected to one end of the second crushing wheel 15. The first gear 16 and the second gear 17 mesh. A support 21 is fixedly connected to the outside of the screening chamber 23. A first motor 20 is fixedly connected to the top of the support 21. The output end of the first motor 20 is fixedly connected to one end of the first crushing wheel 14 through the crushing chamber 1. Multiple baffles 19 are provided on both sides of the inner wall of the crushing chamber 1.

[0024] The first motor 20 starts and drives the first crushing wheel 14 to rotate. Since the first gear 16 and the second gear 17 mesh with each other, the first crushing wheel 14 drives the second crushing wheel 15 to rotate synchronously through gear transmission, and the two crushing wheels rotate in opposite directions. After the material from the feeding mechanism 2 enters the crushing chamber 1, the two crushing wheels cooperate to squeeze and shear the material. At the same time, the baffle strip 19 on the inner wall can slow down the falling speed of the material, prevent the material from passing through the crushing chamber 1 too quickly and causing insufficient crushing, and ensure that the crushed particle size of the Codonopsis pilosula material is uniform.

[0025] The bottom of the screening chamber 23 is fixedly connected to the discharge pipe 4.

[0026] The qualified Codonopsis pilosula material after being screened by the screening mechanism 3 falls to the bottom of the screening bin 23 under the action of gravity, and is finally discharged from the device through the discharge pipe 4.

[0027] Reference Figures 1-3 The crushing chamber 1 is fixedly connected to a protective cover 18, and the first gear 16 and the second gear 17 are both located inside the protective cover 18.

[0028] The protective cover 18 completely covers the first gear 16 and the second gear 17. On the one hand, it can prevent external dust and impurities from entering the gear meshing area and avoid the gears from getting stuck or worn due to impurities, thus affecting the transmission efficiency. On the other hand, it can prevent the gears from coming into contact with external objects or people during rotation, thus eliminating safety hazards.

[0029] Reference Figures 1-3 Both the screening chamber 23 and the conveying pipe 28 are fixedly connected to several support legs 32.

[0030] Several support legs 32 support the screening chamber 23 and the conveying pipe 28 respectively, so that the screening chamber 23 is stably connected to the crushing chamber 1, and the conveying pipe 28 is kept at a preset installation angle of inclination or horizontal, so as to prevent the screening chamber 23 or the conveying pipe 28 from shifting due to vibration during the operation of the device, and ensure the stable operation of the screening and conveying process.

[0031] Working principle: Codonopsis pilosula raw material enters the feeding bin 22 of the feeding mechanism 2 through the feed pipe 13 and the second feed port 12. The first fan 7 and the second fan 9 start to form a negative pressure air duct in the feeding bin 22 to prevent material accumulation in the second feed port 12. The guide plate 6 prevents material from accumulating on the second filter screen 10. The first filter screen 8 and the second filter screen 10 filter impurities in the air. After the material enters the crushing bin 1, the first motor 20 drives the first crushing wheel 14 to rotate. Through the meshing of the first gear 16 and the second gear 17, the second crushing wheel 15 rotates in the opposite direction to crush the material. The baffle bar 19 slows down the falling speed of the material to prevent insufficient crushing. The crushed material falls into the screen in the screening bin 23 of the screening mechanism 3. On screen 24, the vibrating motor 26 drives the screen 24 to vibrate, and the spring 25 helps to maintain the vibration stability. Qualified materials are discharged through the discharge pipe 4, and unqualified materials enter the conveying pipe 28 of the conveying mechanism 5 through the first connecting pipe 27. The second motor 31 starts and drives the rotating shaft 29 and the external spiral blade 30 to rotate, and conveys the unqualified materials to the first feed port 11 through the second connecting pipe 33, and re-enters the feeding mechanism 2 for secondary crushing. The external protective cover 18 of the crushing chamber 1 covers the first gear 16 and the second gear 17 to prevent impurities from affecting the transmission and to eliminate safety hazards. The external support legs 32 of the screening chamber 23 and the conveying pipe 28 play a supporting role to prevent the device from vibrating and causing the components to shift, and to ensure the stable operation of the overall process.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
