Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicinal material crushing, in particular to a Chinese medicinal material crushing device and a Chinese medicinal material multiple processing crushing method. Background Art

[0002] Traditional Chinese medicine (TCM) refers to native herbs used under the guidance of traditional Han Chinese medicine. They are produced in regions with specific natural conditions and ecological environments. They come in a wide variety of types and from a wide range of sources. They are classified based on their pharmacological effects and compositional properties. TCMs are typically dried and stored in a hard, dry block. However, when consumed or used as medicine, these blocks are typically crushed and ground into a powder. This not only facilitates patient consumption but also ensures the full efficacy of the TCM.

[0003] In the existing Chinese medicinal material crushing equipment, such as Chinese patent application CN119972257A, when the Chinese medicinal materials are crushed by the crushing knife, the screw drives the lifting platform to slide on the surface of the positioning frame, and the sieve plate stuck in the lifting platform slides in the slide groove through the slide frame as the lifting platform moves, so that the sieve plate is in a balanced state when it moves, so that the crushed Chinese medicinal materials can be screened out from the sieve holes. The raw materials that cannot be screened out from the sieve plate contact the crushing knife as the sieve plate moves up and down, and are crushed twice, thereby improving the crushing efficiency and avoiding the medicinal materials that are not completely crushed from being stuck in the sieve plate during crushing; when the crushing roller rotates, the rotating block drives the rotating block to rotate on the surface of the crushing roller. As the rotation angle changes, the rotating block flips on the surface of the circular shaft, so that the crushing cutting knife flips outward to crush the Chinese medicinal materials. Since the crushing roller remains in a rotating state, when the crushing cutting knife after flipping rotates to the top as the crushing roller, the rotating block rotates and resets on the surface of the circular shaft, so that the rotating block passes through the rotating groove, avoiding the jamming phenomenon between the crushing roller and the rotating groove when the crushing cutting knife crushes the Chinese medicinal materials.

[0004] However, there are still the following problems: after the Chinese medicinal materials are crushed, if the crushing degree of the processed Chinese medicinal materials is unsatisfactory, they need to be crushed again. At present, when the processed Chinese medicinal materials are crushed again, the staff will put the processed Chinese medicinal materials into the equipment again for processing, or the screen will be moved towards the crushing roller, and the crushing roller will re-process the unqualified processed Chinese medicinal materials on the screen. However, these current methods of re-crushing Chinese medicinal materials affect the processing speed of the Chinese medicinal materials that have not been processed, and reduce the processing efficiency of the Chinese medicinal materials in the equipment. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a traditional Chinese medicinal material crushing equipment, which has the following beneficial effects: 1. The Chinese herbal medicine crushing equipment processes the untreated Chinese herbal medicine by feeding it into the crushing equipment. The middle part of the crushing component crushes the Chinese herbal medicine, and the processed Chinese herbal medicine falls on the sieve. The sieve screens and intercepts the unqualified processed Chinese herbal medicine, causing the unqualified processed Chinese herbal medicine to fall on both sides of the sieve.

[0031] Among them, when performing the crushing treatment of Chinese medicinal materials, the Chinese medicinal materials are piled at the top inlet of the feed hopper 22. The Chinese medicinal materials slide into the guide hopper 25 due to the increase in their own gravity. The guide hopper 25 guides the Chinese medicinal materials to the middle position between the first crushing roller 23 and the second crushing roller 24. The stepping motor 28 is started. The stepping motor 28 drives the traction wheel 210 to rotate. The traction wheel 210 drives the belt 211 to rotate. The belt 211 drives the driven wheel 29 to rotate. The driven wheel 29 drives the second crushing roller 24 to rotate. The second crushing roller 24 drives the second gear 27 to rotate. The second gear 27 drives the first gear 26 to rotate. The first gear 26 drives the first crushing roller 23 to rotate, so that the first crushing roller 23 and the second crushing roller 24 rotate in opposite directions, so that the first crushing roller 23 and the second crushing roller 24 use the middle part to perform the crushing treatment on the Chinese medicinal materials. The processed Chinese medicinal materials fall onto the screen 31.

[0032] Example 3, asFigures 7 - 12 As shown, the difference from the above embodiment is that the auxiliary mechanism 3 further includes a vibration motor 32. A screen 31 is fixedly installed at the top end of the body 1. The screen 31 is located inside the communication part between the treatment box 21 and the body 1. The transverse dimension of the screen 31 is adapted to the dimension of the communication part between the treatment box 21 and the body 1.

[0036] Working principle of the present invention: The unprocessed Chinese medicinal materials are fed into the crushing device for processing, so that the middle part of the crushing assembly 2001 crushes the Chinese medicinal materials. The processed Chinese medicinal materials fall onto the screen 31. The screen 31 sieves and retains the unqualified processed Chinese medicinal materials, so that the unqualified processed Chinese medicinal materials fall to both sides of the screen 31. Then, the conveying spoon 36 conveys the unqualified processed Chinese medicinal materials on the screen 31 back to both sides of the crushing assembly 2001, so that the unqualified processed Chinese medicinal materials are reprocessed, so as to use the middle part of the crushing assembly 2001 to crush the unprocessed Chinese medicinal materials, and use both sides of the crushing assembly 2001 to reprocess the unqualified processed Chinese medicinal materials, so that the reprocessing process of the Chinese medicinal materials in the crushing device does not affect the crushing process of the unprocessed Chinese medicinal materials as a whole, and at the same time, it also avoids the situation of component conflicts in the processing process caused by the staff putting back the unqualified processed Chinese medicinal materials again or the screen 31 leaning towards the crushing assembly 2001 during the reprocessing of the unqualified processed Chinese medicinal materials, thereby improving the processing efficiency of the crushing device for Chinese medicinal materials; Among them, when performing crushing treatment on traditional Chinese medicinal materials, the traditional Chinese medicinal materials are stacked at the top inlet of the feeding hopper 22. The traditional Chinese medicinal materials slide into the guiding hopper 25 due to the increase in their own gravity caused by the stacking. The guiding hopper 25 guides the traditional Chinese medicinal materials to the middle position between the first crushing roller 23 and the second crushing roller 24. Then, the stepping motor 28 is started. The stepping motor 28 drives the traction wheel 210 to rotate. The traction wheel 210 drives the belt 211 to rotate. The belt 211 drives the driven wheel 29 to rotate. The driven wheel 29 drives the second crushing roller 24 to rotate. The second crushing roller 24 drives the second gear 27 to rotate. The second gear 27 drives the first gear 26 to rotate. The first gear 26 drives the first crushing roller 23 to rotate, so that the first crushing roller 23 and the second crushing roller 24 rotate in opposite directions, so that the first crushing roller 23 and the second crushing roller 24 use the middle part to perform crushing treatment on the traditional Chinese medicinal materials. The treated traditional Chinese medicinal materials fall onto the screen 31; As the treated traditional Chinese medicinal materials fall onto the screen 31, the vibration motor 32 is started. The vibration motor 32 vibrates the screen 31 by using the connecting frame 33, so that the screen 31 vibrates the treated traditional Chinese medicinal materials, making the unqualified treated traditional Chinese medicinal materials be screened and intercepted on the screen 31 and fall to both sides of the screen 31. Then, the servo motor 311 is started. The servo motor 311 drives the second toothed roller 312 to rotate. The second toothed roller 312 drives the toothed belt 313 to rotate.
