Technical Field
[0001] This utility model relates to the field of medicinal material processing devices, and in particular to an integrated device for grinding and mixing traditional Chinese medicine. Background Technology
[0002] Traditional Chinese medicine (TCM), a treasure of Chinese medicine, has a complex and meticulous preparation process. Grinding and stirring are key steps in TCM processing. Grinding breaks TCM herbs into powder through mechanical action to better extract the active ingredients. Stirring mixes the TCM herbs or their extracts evenly to achieve the desired therapeutic effect. With the advancement of technology, TCM grinding and stirring equipment has undergone a transformation from traditional manual methods to modern machinery, greatly improving the efficiency and quality of TCM preparation.
[0003] Traditional Chinese medicine grinding equipment mostly uses manual grinding or simple mechanical crushing methods, which have problems such as low grinding efficiency, uneven particle size, and easy contamination. Manual grinding is time-consuming and laborious, and it is difficult to ensure the uniformity and consistency of grinding. Simple mechanical crushing equipment often cannot accurately control the particle size and is prone to impurity contamination, affecting the extraction effect and safety of Chinese medicine. Although machine grinding is efficient, the electric equipment may generate heat during the grinding process, which may affect some active ingredients of the medicinal materials and reduce the efficacy.
[0004] Similarly, traditional Chinese medicine mixing equipment also has problems such as uneven mixing, the creation of dead corners, and high energy consumption. Uneven mixing can lead to an imbalance in the proportion of various components in Chinese medicine extracts, affecting the efficacy. The existence of dead corners will prevent some Chinese medicinal materials from being fully mixed, resulting in waste. In addition, traditional mixing equipment has high energy consumption, which is not conducive to energy conservation, emission reduction and sustainable development.
[0005] Therefore, designing an integrated device that combines grinding function to maintain the activity of Chinese medicine with thorough mixing of the ground powder is an urgent problem to be solved in the field of Chinese medicine. Utility Model Content

Detailed Implementation
[0028] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail below:
[0029] This utility model discloses an integrated device for grinding and mixing traditional Chinese medicine, such as... Figure 1 As shown, an integrated grinding and stirring device for traditional Chinese medicine includes a tank 1. A motor 6 is bolted to the bottom of the tank 1. One end of a drive shaft 3 is connected to the output end of the motor 6 via a coupling. The other end of the drive shaft 3 extends upward through the tank 1, and a stirring structure is installed on the outer wall of the drive shaft 3. A grinding assembly is installed on the top of the tank 1. The grinding assembly and the stirring structure are driven by the same drive shaft 3. A feed pipe 12 is vertically arranged at the bottom of the tank 1, penetrating the interior of the tank 1. In this embodiment, the motor 6 serves as a power source, driving the grinding assembly and the stirring structure to work synchronously via the drive shaft 3, thus achieving integrated grinding and stirring of traditional Chinese medicine. After the motor 6 starts, it drives the drive shaft 3 to rotate via the coupling. The drive shaft 3 penetrates the tank 1, driving the grinding assembly at the top to perform grinding operations on one hand, and driving the stirring structure inside the tank 1 to perform stirring on the other. The integrated design improves work efficiency and reduces equipment space occupation. At the same time, the same drive shaft 3 drives grinding and stirring, ensuring the synchronicity of the two actions and improving the uniformity of traditional Chinese medicine processing.
[0030] Additionally, it should be noted that the feed pipe 12 is pre-sealed to facilitate thorough mixing of the powder.
[0031] like Figure 1 , 4As shown in Figure 7, the grinding assembly includes a powder receiving tray 2, a lower grinding disc 21, a grinding groove 211, and an upper grinding disc 22. The powder receiving tray 2 is bolted to the top of the tank body 1. The lower grinding disc 21 is fixedly installed inside the powder receiving tray 2. The upper grinding disc 22 is arranged on the upper side of the lower grinding disc 21. The top of the drive shaft 3 extends through the powder receiving tray 2, the lower grinding disc 21, and the upper grinding disc 22 in sequence to the upper side of the upper grinding disc 22, and is fixed to the top of the upper grinding disc 22 by a fixing component. A feeding structure is installed on the top of the upper grinding disc 22. A feeding port is opened on the top of the upper grinding disc 22 corresponding to the feeding structure. Grinding grooves 211 are respectively opened on the contact surfaces of the upper grinding disc 22 and the lower grinding disc 21. In this embodiment, the Chinese medicine enters the grinding groove 211 through the feeding structure, and the upper and lower grinding discs rotate relative to each other to generate a grinding effect, grinding the Chinese medicine into powder. The drive shaft 3 drives the upper grinding disc 22 to rotate. The grinding mechanism moves relative to the fixed lower grinding disc 21, grinding the Chinese medicine into powder between the upper grinding disc 22 and the lower grinding disc 21. The ground powder falls into the tank 1 through the feeding hole 51 at the bottom of the powder receiving disc 2. The design of the grinding component ensures thorough grinding of the Chinese medicine and improves grinding efficiency. At the same time, the feeding hole 51 allows the powder to fall smoothly into the tank 1, avoiding accumulation and waste. In addition, grinding with a traditional grinding disc gradually breaks down the cell walls of the Chinese medicine through slow rotation, releasing more effective ingredients. This method better preserves the original aroma and efficacy of the medicinal materials because no high temperature is generated during the grinding process, avoiding damage to the medicinal components. While machine grinding is more efficient, the electric equipment generates heat during the grinding process, which can affect some active ingredients of the medicinal materials, thereby reducing efficacy.
[0032] like Figure 1 As shown, the feeding structure includes a support frame 4, a mounting ring 41, and a feeding funnel 42. The support frame 4 is bolted to the top of the upper grinding disc 22. The mounting ring 41 is located inside the support frame 4. The feeding funnel 42 is bolted to the inside of the mounting ring 41. The outlet of the feeding funnel 42 extends into the feeding port at the top of the upper grinding disc 22. In this embodiment, the Chinese herbal raw materials are poured in from the inlet of the feeding funnel 42 and fall into the grinding tank 211 through the guidance of the funnel. The outlet of the funnel is opposite to the feeding port at the top of the upper grinding disc 22, ensuring that the Chinese herbal medicine can be accurately fed into the grinding area. The design of the feeding structure simplifies the process of adding Chinese herbal raw materials and improves the convenience of operation. At the same time, the guiding effect of the funnel ensures that the Chinese herbal raw materials can be evenly distributed, which is conducive to the uniform grinding. However, it should be noted that some herbs need to be simply chopped before being added.
[0033] like Figure 1 , 2As shown, the fixing assembly includes positioning studs 23, fixing posts 31, fixing plates 32, and fixing nuts 33; several positioning studs 23 are embedded and fixed on the top of the upper grinding disc 22; the portion of the drive shaft 3 located on the upper side of the upper grinding disc 22 is integrally formed with a rectangular column-shaped fixing post 31; the fixing plate 32 is fitted onto the fixing post 31, and the interior of the fixing plate 32 is provided with rectangular holes that match the cross-section of the fixing post 31, as well as several through holes that match the positioning studs 23; after the fixing plate 32 is fitted onto the fixing studs 23 and the fixing post 31, the fixing nuts 33 are threadedly connected to the outer side walls of the fixing studs 23 to achieve the fixing between the drive shaft 3 and the upper grinding disc 22; in this embodiment, the fixing assembly is used to fix the connection between the drive shaft 3 and the upper grinding disc 22. The fixing post 31 on the drive shaft 3 passes through the rectangular hole on the fixing plate 32, and the through hole on the fixing plate 32 is opposite to the positioning stud 23 on the top of the upper grinding disc 22; the fixing nut 33 is threaded to fix the fixing plate 32, drive shaft 3 and upper grinding disc 22 together; the design of the fixing component ensures a stable connection between the drive shaft 3 and the upper grinding disc 22, avoiding vibration and loosening during the grinding process; at the same time, the fixing method is simple and reliable, and easy to install and maintain.
[0034] like Figure 3 , 5 As shown, the bottom of the powder receiving tray 2 has several feeding holes 51 around the edge of the lower grinding disc 21. An inclined block 5 is provided between the feeding holes 51 and the inner wall of the powder receiving tray 2 to facilitate the concentration of the powder at the feeding port. In this embodiment, the powder receiving tray 2 is used to collect the ground powder and allow it to fall into the tank 1 through the feeding holes 51. The design of the inclined block 5 helps the powder to concentrate at the feeding port. The ground powder falls onto the powder receiving tray 2 and is concentrated at the feeding holes 51 by the guiding action of the inclined block 5. As the powder accumulates, it falls into the tank 1 through the feeding holes 51. The design of the powder receiving tray 2 and the feeding holes 51 ensures the smooth collection and falling of the powder, avoiding waste and accumulation. The guiding action of the inclined block 5 improves the efficiency of the powder falling; simultaneously, the vibration of the motor and the frictional vibration of the upper grinding disc 22 and the lower grinding disc 21 are transmitted to the powder receiving tray 2, promoting the falling of the powder.
[0035] like Figure 4 , 6As shown, the stirring structure includes a stirring ring 7 and stirring bars 71. The stirring ring 7 is bolted to the outer wall of the drive shaft 3. The stirring bars 71 are welded inside the stirring ring 7. In this embodiment, the stirring structure is used to stir the traditional Chinese medicine in the tank 1. The drive shaft 3 drives the stirring ring 7 to rotate, and the stirring bars 71 stir the traditional Chinese medicine in the tank 1 under the action of the stirring ring 7. The arrangement of multiple stirring rings 7 and stirring bars 71 ensures the uniformity and thoroughness of the stirring. The design of the stirring structure improves the stirring efficiency of the traditional Chinese medicine and ensures the uniform mixing of the traditional Chinese medicine. At the same time, the arrangement of multiple stirring rings 7 and stirring bars 71 makes the stirring more thorough, which is conducive to the effective extraction of traditional Chinese medicine.
[0036] like Figure 4 , 6 As shown, the stirring ring 7 is a ring-shaped structure with the same outline between the drive shaft 3 and the inner wall of the tank 1; there are N stirring rings 7, N≥2; there are M stirring strips 71, M≥2; the stirring strips 71 within the same stirring ring 7 are not arranged in parallel; scrapers 72 are fixedly installed on the outer wall and bottom of the stirring ring 7; the scrapers 72 are in close contact with the inner wall of the tank 1; the scrapers 72 are made of rubber; in this embodiment, scrapers 72 are fixedly installed on the outer wall and bottom of the stirring ring 7, used to scrape off residual medicinal powder from the inner wall of the tank 1. During the rotation of the stirring ring 7, the scrapers 72 are in close contact with the inner wall of the tank 1, scraping off the medicinal powder adhering to the inner wall; as the stirring ring 7 continues to rotate, the scraped medicinal powder is fully mixed; the design of the scrapers 72 avoids the residue and waste of medicinal powder on the inner wall of the tank 1, improving the utilization rate of traditional Chinese medicine; at the same time, the rubber scrapers 72 have a certain elasticity, which can be in close contact with the inner wall of the tank 1, ensuring the scraping effect;
[0037] like Figure 1 As shown, a bracket 11 is installed on the outer wall of the tank 1. In this embodiment, the bracket 11 is fixed to the ground or workbench by bolts or other connecting parts to provide stable support for the tank 1. During the operation of the device, the bracket 11 remains stationary to ensure the stability and safety of the tank 1. This improves the stability and safety of the device and avoids vibration and shaking during grinding and stirring. At the same time, the material and structure of the bracket 11 ensure its load-bearing capacity and durability.
[0038] The implementation principle of this utility model embodiment is as follows:
[0039] When using this invention, first ensure that all parts of the device are installed completely and securely, and that the motor 6, grinding components, stirring structure, and feeding pipe 12 are in normal working condition; place an appropriate amount of Chinese herbal raw materials into the feeding funnel 42, ready for grinding; connect the power supply and start the motor 6; the motor 6 drives the drive shaft 3 to start rotating through the coupling; when the drive shaft 3 rotates, the upper grinding disc 22 fixed at its upper end rotates accordingly, forming relative motion with the lower grinding disc 21; the Chinese herbal raw materials fall from the feeding funnel 42 into the grinding tank 211, and are gradually turned into powder by the squeezing and grinding action of the upper and lower grinding discs; the ground powder falls onto the powder receiving plate 2, and gradually falls into the tank 1 through the guiding action of the feeding hole 51 and the inclined block 5; at the same time, the rotation of the drive shaft 3 also drives the stirring structure to stir. The stirring ring 7 and stirring bar 71 rotate inside the tank 1 to thoroughly mix the Chinese herbal powder. The scraper 72 on the outside and bottom of the stirring ring 7 adheres closely to the inner wall of the tank 1, scraping off the powder adhering to the wall to ensure uniformity and thoroughness of mixing. The motor 6 runs continuously, and the grinding and stirring processes are carried out simultaneously until the predetermined grinding and stirring effect is achieved. During this process, the speed of the motor 6 can be adjusted as needed to control the intensity and speed of grinding and stirring. After grinding and stirring are completed, the motor 6 is turned off and the power is disconnected. The discharge pipe 12 valve at the bottom of the tank 1 is opened to discharge the ground Chinese herbal powder from the device. The inside of the device is cleaned in preparation for the next use.
