Description

Technical Field

[0001] This invention belongs to the field of biopharmaceutical manufacturing technology, and more specifically, relates to a multifunctional integrated device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] The processing of Chinese medicinal herbs is an important part of traditional Chinese medicine. It refers to the process of processing Chinese medicinal materials according to their properties and clinical treatment needs. Traditional processing techniques for Chinese medicinal herbs mostly rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the consistency and stability of product quality. With the development of modern technology, people have increasingly higher requirements for the quality of Chinese medicinal herbs, and traditional methods can no longer meet the needs of modern production and the market.

[0003] A search revealed a patent with authorization announcement number CN112755129B, which discloses a processing equipment for traditional Chinese medicine decoction pieces. The equipment includes a motor, top cover, pulverizing cylinder, discharge pipe, feed hopper, airflow distribution pipe, conveying pipe, and conveying screw. The equipment also includes support legs, airflow distribution pipe shock absorption components, and heat dissipation fins. This equipment uses high-speed airflow to cause materials to collide and pulverize. However, this equipment still has certain limitations in use. When materials fall vertically through the air vent, only the portion that first comes into contact with the high-speed airflow can be effectively pulverized, while subsequent materials may pass directly through the airflow area without achieving the expected pulverization effect. This not only reduces processing efficiency but may also lead to inconsistent product quality, especially for products like traditional Chinese medicine decoction pieces that require high fineness of raw materials, potentially affecting the efficacy of the medicine. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a multifunctional integrated device for processing Chinese herbal medicine slices.

[0005] The technical solution of this invention is: a multifunctional integrated device for processing Chinese herbal medicine slices, comprising a base plate, a support base, and a processing tank. The support base is fixedly connected to the base plate, and the base plate and support base are the load-bearing carriers of this device. The processing tank is installed on top of the support base, and the top of the processing tank has a discharge port for Chinese herbal medicine powder, and the bottom of the processing tank has a collection port for dried Chinese herbal medicine debris. The processing tank is a container for processing Chinese herbal medicine slices; it also includes: a feeding frame, which is set on the upper outer side of the processing tank by a mounting block. A feeding frame is ring-shaped and surrounds the outer wall of the processing tank. The lower part of the feeding frame has a narrowed material guide port, and the bottom of the feeding frame is the feeding port. A mounting frame is located on the lower inner wall of the feeding frame, and the mounting frame is a ring-shaped frame fixed to the lower inner wall of the feeding frame. A solenoid valve is installed on the top of the support base, and the solenoid valve is located at the recovery port at the bottom of the processing tank. An airflow pulverizing mechanism is located on the top surface of the support base and is used to spray and pulverize the dried Chinese medicinal materials inside the processing tank. The airflow pulverizing mechanism includes... Includes: multiple high-pressure air pumps, circumferentially mounted on the top surface of the support base with the blasting vessel as the center; multiple guide pipes, the same number as the high-pressure air pumps, with one end sealed and connected to the lower side wall of the blasting vessel, the inlets of symmetrical guide pipes facing opposite directions, and the other end of the guide pipes connected to the air outlet of the high-pressure air pumps; a feeding pipe, one end of which is connected to the feeding port at the bottom of the feeding frame, and the other end of which is connected to the guide pipes; and a discharge nozzle, installed at the air outlet of each guide pipe. The discharge nozzles are circumferentially distributed inside the lower part of the processing tank. The discharge nozzles are used to use high-speed airflow to cause the materials to collide with each other and achieve pulverization. The feeding component is set inside the feeding pipe. The feeding component is used to assist in the regular flow of the dried Chinese medicine materials in the feeding frame into the guiding pipe, avoiding excessive material falling into the guiding pipe in a short time, which would easily cause blockage of the dried Chinese medicine materials in the guiding pipe. This ensures that the discharge nozzles spray out only an appropriate amount of dried Chinese medicine materials at high speed at a time, so that the dried Chinese medicine materials are effectively broken into powdered raw materials of Chinese medicine decoction pieces under high-speed airflow.

[0006] Furthermore, the processing tank is shaped like a truncated cone, wider at the top and narrower at the bottom. The outlet at the top of the processing tank is an opening for collecting the processed powder. The shape of the processing tank reduces the resistance of airflow entering the tank, allowing the airflow to carry the crushed Chinese medicine powder more smoothly through the outlet of the processing tank. At the same time, the insufficiently crushed Chinese medicine residue sinks to the bottom of the processing tank. The discharge nozzles are arranged circumferentially inside the processing tank and form a circle, with two opposite discharge nozzles facing each other. The nozzle opening is smaller than the diameter of the guide pipe and slightly larger than the crushed Chinese medicine material. When the high-speed airflow enters the discharge nozzle from the guide pipe, the smaller flow diameter further accelerates the airflow speed, allowing the high-speed airflow to carry the Chinese medicine material at high speed to achieve effective crushing.

[0007] Furthermore, the feeding component includes: a servo motor, symmetrically mounted within the mounting frame, the output shaft of the servo motor extending through the mounting frame and into the upper part of the feeding pipe; a spiral conveying roller, mounted on the output shaft of the servo motor, located within the upper part of the feeding pipe, the spacing between the conveying threads of the spiral conveying roller being the distance for guiding a single piece of dried Chinese medicine material; a funnel, positioned within the lower part of the feeding pipe; and a check valve, installed at the lower outlet of the funnel, the check valve providing unidirectional flow from top to bottom through the funnel. Driven by the servo motor, the spiral conveying roller rotates at the top outlet of the feeding pipe, allowing the dried Chinese medicine material leaking from the feeding port of the feeding frame to sequentially and quantitatively fall into the funnel under the conveying of the spiral conveying roller, finally entering the guide pipe through the check valve, and finally being ejected from the discharge nozzle following the high-speed airflow within the guide pipe.

[0008] Furthermore, the top of the processing tank is provided with a diversion mechanism, which includes: a diversion pipe, located at the discharge port at the top of the processing tank, the diversion pipe being a three-way pipe used to divert the crushed Chinese medicine powder and Chinese medicine granules that rise with the airflow; a feed pipe, connected to the opening at the lower part of the diversion pipe, the feed pipe being connected to the discharge port at the top of the processing tank; a powder collection pipe, connected to one side opening at the upper part of the diversion pipe, the powder collection pipe being a collection channel for Chinese medicine powder; a granule return pipe, connected to the other side opening at the upper part of the diversion pipe, the granule return pipe being a recovery channel for Chinese medicine granules; and a switching component, located at the intersection of the three-way openings inside the diversion pipe, the switching component being used to switch between the powder collection pipe and the granule return pipe, so that the powder collection pipe or the granule return pipe can be connected to the feed pipe respectively, allowing the Chinese medicine powder and Chinese medicine granules to flow into the powder collection pipe and the granule return pipe respectively, facilitating the direct collection of Chinese medicine powder and the recovery and processing of Chinese medicine granules.

[0009] Furthermore, the switching component includes: a three-way valve, rotatably and sealingly mounted at the intersection of three ports inside the diverter pipe; the three-way valve is cylindrical with openings in three directions, the openings of the three-way valve being perpendicularly intersecting; when adjacent perpendicular openings of the three-way valve are open, the remaining opening will be blocked and closed; a mounting shaft, fixed to one side of the three-way valve, the mounting shaft rotatably penetrating through the side wall of the diverter pipe; and a pharmaceutical sieve, disposed at one of the openings of the three-way valve facing opposite directions, the pharmaceutical sieve being used to separate gas at the feed pipe. The device contains Chinese herbal powder and granules; a stepper motor is installed on the outer wall of the diversion pipe, and the output shaft of the stepper motor is connected to the mounting shaft. The stepper motor drives the three-way valve to rotate in the diversion pipe through the mounting shaft, and the stepper motor can drive the three-way valve to rotate 180 degrees according to a preset value, so that the three-way valve can connect the feed pipe and the powder collection pipe, or connect the feed pipe and the granule return pipe. When the feed pipe and the powder collection pipe are connected, the medicinal screen will block at the feed pipe, so that the Chinese herbal powder and granules in the airflow are screened.

[0010] Furthermore, a reflux mechanism is provided between the particle return pipe and the feeding frame. The reflux mechanism includes: a cover plate installed at the top annular opening of the feeding frame; an air outlet screen installed on the cover plate, used to balance the air pressure inside the feeding frame; a connecting pipe connected to the outlet of the particle return pipe, with the end of the connecting pipe away from the particle return pipe being closed; and a flexible hose connected between the connecting pipe and the cover plate, extending through the cover plate into the feeding frame. When the three-way valve is switched to connect the feed pipe and the particle return pipe, the connecting pipe and the flexible hose are used to return the Chinese medicine particles screened by the medicinal screen to the feeding frame, facilitating the secondary flow of the Chinese medicine particles in the feeding frame to the airflow pulverizing mechanism for secondary crushing, so that the Chinese medicine dry material particles that have not been crushed to the required standard are fully crushed.

[0011] Furthermore, it also includes a recycling mechanism, which comprises: a collection tank, disposed on the base plate, with the top collection port of the collection tank aligned with the outlet of the solenoid valve; a reflux pump, mounted on the base plate; a connecting pipe, connecting the collection tank and the inlet of the reflux pump; and a fragment reflux pipe, one end of which is connected to the outlet of the reflux pump, and the other end of which is connected to the lower part of the feeding frame. After the solenoid valve is opened, the collection tank collects the completely crushed Chinese herbal medicine fragments at the bottom of the processing tank, and then the reflux pump guides the Chinese herbal medicine fragments inside the collection tank back to the feeding frame for secondary feeding through the connecting pipe and the fragment reflux pipe, so that the Chinese herbal medicine fragments can also flow back into the airflow pulverizing mechanism for secondary crushing, further improving the yield of crushed dried Chinese herbal medicine materials.

[0012] Furthermore, the fragment return pipe is a rigid pipe, and the fragment return pipe branches into two sections at the outlet pipe of the feeding frame. One section is horizontally connected to the lower side of the feeding frame, and the other section is inclined downwards and connected to the side of the feeding frame near the bottom. The branched pipe of the fragment return pipe helps the fragments of Chinese medicine to disperse into the feeding frame, reducing the situation of fragments of Chinese medicine sticking together or causing blockage, and accelerating the rate of circulation and crushing of fragments of Chinese medicine.

[0013] The beneficial effects of this invention are: 1. This invention utilizes a high-pressure air pump and a guide pipe design, with the feed pipe connected to the guide pipe, to create a high-speed impact of airflow within the processing tank. This effectively promotes the mutual collision of materials, improving pulverization efficiency. Furthermore, a servo motor drives the spiral conveyor roller, ensuring that the dried Chinese medicine materials enter the guide pipe in a regular manner, preventing blockage and ensuring that an appropriate amount of material is sprayed out each time, thus improving the pulverization effect.

[0014] 2. This invention can guide the crushed Chinese medicine powder and granules to the powder collection pipe and the granule return pipe respectively through the diversion pipe and the three-way valve, ensuring that only Chinese medicine powder that meets the specified particle size is collected, and granules that do not meet the standard are recycled and processed, thereby improving the particle size uniformity of the final product.

[0015] 3. This invention uses a particle return pipe to return substandard Chinese medicine particles to the feeding frame for secondary feeding and crushing, ensuring that all materials are fully crushed and improving the yield. At the same time, the fragment return pipe collects incompletely crushed Chinese medicine fragments from the bottom of the processing tank and reintroduces them into the feeding frame for secondary crushing, further improving the utilization rate of materials.

[0026] Example 1: A multi-functional integrated device for processing Chinese herbal medicine slices, such as... Figures 1-4As shown, the device includes a base plate 1, a support base 2, and a processing tank 3. The support base 2 is fixedly connected to the base plate 1. The base plate 1 and the support base 2 are the load-bearing carriers of this equipment. The processing tank 3 is installed on top of the support base 2. The top of the processing tank 3 has a discharge port 31 for Chinese herbal powder, and the bottom of the processing tank 3 has a collection port for dried Chinese herbal fragments. The processing tank 3 is a container for processing Chinese herbal decoction pieces. It also includes a feeding frame 4, which is set on the upper outer side of the processing tank 3 via a mounting block 41. The feeding frame 4 is annular and surrounds the outer wall of the processing tank 3. The material guide port is narrowed, and the bottom of the feeding frame 4 is the feeding port; the mounting frame 42 is set on the lower part of the inner wall of the feeding frame 4, and the mounting frame 42 is a ring-shaped frame that is fixed to the lower inner wall of the feeding frame 4; the solenoid valve 5 is installed on the top of the support base 2, and the solenoid valve 5 is located at the recovery port at the bottom of the processing tank 3; the airflow pulverizing mechanism 6 is set on the top surface of the support base 2 and is used to spray and pulverize the dried Chinese medicine materials in the processing tank 3; the airflow pulverizing mechanism 6 includes: a high-pressure air pump 61, which is provided in multiple units and is circumferentially mounted around the processing tank 3. Mounted on the top surface of support base 2; multiple guide pipes 62, the same number as the high-pressure air pump 61, with one end sealed and connected to the lower side wall of the processing tank 3, the inlets of two symmetrical guide pipes 62 facing opposite directions, the other end of the guide pipes 62 connected to the air outlet of the high-pressure air pump 61; a feeding pipe 63, one end connected to the feeding port at the bottom of the feeding frame 4, the other end connected to the guide pipes 62; discharge nozzles 64, installed at the air outlet of each guide pipe 62, multiple discharge nozzles 64 circumferentially distributed on the processing tank 3. Inside the lower part of the tank 3, the discharge nozzle 64 is used to use high-speed airflow to cause the materials to collide with each other and achieve crushing; the feeding component 7 is set inside the feeding pipe 63. The feeding component 7 is used to assist the regular flow of the dried Chinese medicine materials in the feeding frame 4 into the guide pipe 62, so as to avoid too much material falling into the guide pipe 62 in a short time, which would easily cause the dried Chinese medicine materials to be blocked in the guide pipe 62. This allows the discharge nozzle 64 to spray out only an appropriate amount of dried Chinese medicine materials at high speed at a time, so that the dried Chinese medicine materials are effectively crushed into powder raw materials of Chinese medicine decoction pieces under high-speed airflow.

[0027] like Figure 2 and Figure 3As shown, the processing tank 3 is a truncated cone shape that is wider at the top and narrower at the bottom. The discharge port 31 at the top of the processing tank 3 is the opening for collecting the processed powder. The shape of the processing tank 3 reduces the resistance of the airflow entering the tank, allowing the airflow to carry the crushed Chinese medicine powder more smoothly through the discharge port 31 of the processing tank 3. At the same time, the insufficiently crushed Chinese medicine residue sinks to the bottom of the processing tank 3. The discharge nozzles 64 are arranged circumferentially inside the processing tank 3 and form a circle. The two opposite discharge nozzles 64 face each other. The nozzle opening of the discharge nozzle 64 is smaller than the diameter of the guide pipe 62 and slightly larger than the crushed Chinese medicine material. When the high-speed airflow enters the discharge nozzle 64 from the guide pipe 62, the flow diameter becomes smaller, which can further accelerate the airflow speed, so that the high-speed airflow can carry the Chinese medicine material to impact at high speed to achieve effective crushing.

[0028] like Figure 3 and Figure 4 As shown, the feeding component 7 includes: a servo motor 72, symmetrically mounted within the mounting frame 42, with the output shaft of the servo motor 72 extending through the mounting frame 42 and into the upper part of the feeding pipe 63; a spiral conveying roller 71, mounted on the output shaft of the servo motor 72, located in the upper part of the feeding pipe 63, with the spacing between the conveying threads of the spiral conveying roller 71 being the distance for guiding a single piece of dried Chinese herbal medicine; a funnel 73, located in the lower part of the feeding pipe 63; and a stop. Check valve 74 is installed at the lower outlet of funnel 73. Check valve 74 allows unidirectional flow of funnel 73 from top to bottom. The servo motor 72 drives the spiral conveyor roller 71 to rotate at the top opening of the discharge pipe 63, so that the dried Chinese medicine material leaking from the discharge port of the discharge frame 4 can be conveyed by the spiral conveyor roller 71 and fall into the funnel 73 in a quantitative manner. Finally, it enters the guide pipe 62 through check valve 74 and is sprayed out from the discharge nozzle 64 with the high-speed airflow in the guide pipe 62.

[0029] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the top of the processing tank 3 is equipped with a diversion mechanism 8, which includes: a diversion pipe 81, located at the discharge port 31 at the top of the processing tank 3; the diversion pipe 81 is a three-way pipe used to divert the Chinese herbal powder and granules that rise with the airflow after crushing; a feed pipe 82, connected to the opening at the lower part of the diversion pipe 81, and connected to the discharge port 31 at the top of the processing tank 3; a powder collection pipe 83, connected to one side opening at the upper part of the diversion pipe 81, serving as a collection channel for the Chinese herbal powder; and a granule return pipe 84, connected to the diversion pipe 81. At the other end of the upper part of pipe 81, the particle return pipe 84 serves as a recycling channel for Chinese medicine particles. A switching element 9 is located at the intersection of three ports inside the diversion pipe 81. The switching element 9 is used to switch between the powder collection pipe 83 and the particle return pipe 84, allowing either the powder collection pipe 83 or the particle return pipe 84 to connect to the feed pipe 82 respectively. This enables the Chinese medicine powder and particles to flow into the powder collection pipe 83 and the particle return pipe 84 respectively, facilitating convenient and direct collection of Chinese medicine powder and recycling of Chinese medicine particles. The switching element 9 includes a three-way valve 91, which is rotatably and sealingly mounted on the diversion pipe 81. 1. At the intersection of the three internal ports, the three-way valve 91 is cylindrical with openings in three directions. The openings of the three-way valve 91 are perpendicularly intersecting. When adjacent perpendicular openings of the three-way valve 91 are open, the remaining opening will be blocked and closed. A mounting shaft 92 is fixed to one side of the three-way valve 91 and rotates through the side wall of the diversion pipe 81. A medicinal sieve 93 is installed at one of the openings of the three-way valve 91 facing opposite directions. The medicinal sieve 93 is used to separate Chinese medicine powder and granules in the gas at the feed pipe 82. A stepper motor 94 is installed on the diversion pipe 8. On the outer wall of 1, the output shaft of the stepper motor 94 is connected to the mounting shaft 92. The stepper motor 94 drives the three-way valve 91 to rotate in the diversion pipe 81 through the mounting shaft 92. The stepper motor 94 can drive the three-way valve 91 to rotate 180 degrees according to the preset value, so that the three-way valve 91 can connect the feed pipe 82 and the powder collection pipe 83, or connect the feed pipe 82 and the particle return pipe 84. When the feed pipe 82 and the powder collection pipe 83 are connected, the medicinal sieve 93 will block at the feed pipe 82, so that the Chinese medicine powder and Chinese medicine particles in the airflow are screened.

[0030] When using this device to process powdered raw materials of traditional Chinese medicine, firstly, the high-pressure air pump 61 on the support base 2 is activated simultaneously. Then, the dried Chinese medicine material to be processed is placed into the feeding frame 4. Since the feeding frame 4 surrounds the outer wall of the processing tank 3, its bottom is designed with a narrowed material guide port to ensure that the material can fall evenly and orderly into the feeding pipe 63. The feeding pipe 63 is equipped with a spiral conveying roller 71 driven by a servo motor 72. The material is regularly guided into the guide pipe 62 by rotation. During this process, the thread pitch of the spiral conveying roller 71 is precisely set to ensure that only an appropriate amount of material is conveyed each time, avoiding blockage caused by excessive material in the guide pipe 62. Since a check valve 74 is installed at the funnel 73 inside the feeding pipe 63, The airflow in the guide pipe 62 is prevented from flowing into the feed pipe 63 and can only be ejected from the discharge nozzle 64. After the material passes through the funnel 73 and check valve 74, it enters the guide pipe 62 and is driven by the high-speed airflow generated by the high-pressure air pump 61, and is ejected through the discharge nozzle 64. Under the action of the high-speed airflow, the material impacts at high speed in the processing tank 3 and achieves preliminary crushing. Since the processing tank 3 is a truncated cone shape that is wider at the top and narrower at the bottom, the resistance to airflow entering the processing tank 3 is reduced, allowing the crushed Chinese medicine powder to be discharged more smoothly through the discharge port 31 at the top of the processing tank 3. At the same time, the insufficiently crushed dry Chinese medicine residue will sink to the bottom of the processing tank 3. Since the discharge nozzles 64 are circumferentially distributed inside the processing tank 3, and the two opposite discharge nozzles 64 The opposing airflows further enhance the crushing effect of the materials. When the crushed materials rise to the top of the processing tank 3 with the airflow, the three-way valve 91 in the diversion pipe 81 is connected to the feed pipe 82 and the powder collection pipe 83. The medicinal powder and granules floating from the discharge port 31 at the top of the processing tank 3 are separated by the medicinal sieve 93. The medicinal powder can pass through the medicinal sieve 93 and enter the powder collection pipe 83 for easy collection by the user, while the substandard medicinal granules will be screened down by the medicinal sieve 93. After the initial crushing of the dry medicinal materials inside the feed frame 4 is completed in the processing tank 3, and the amount of medicinal powder collected in the powder collection pipe 83 is significantly reduced, the airflow in the processing tank 3 at this time mainly consists of medicinal granules and debris. At this point, by activating the stepper motor 94, the output shaft of the stepper motor 94 drives the mounting shaft 92 and the three-way valve 91 to rotate 180 degrees within the diversion pipe 81. This connects the three-way valve 91 within the diversion pipe 81 to the feed pipe 82 and the particle return pipe 84. The opening of the three-way valve 91 with the medicinal sieve 93 is adjusted to the top of the inner wall of the diversion pipe 81, so that the medicinal sieve 93 is no longer within the feed pipe 82. The rising airflow continues to carry most of the Chinese herbal medicine particles into the particle return pipe 84 for subsequent recycling. Thus, the stepper motor 94 controls the three-way valve 91 to circulate within the diversion pipe 81, separating the crushed Chinese herbal medicine powder and particles within the processing tank 3.This facilitates the collection and reflux crushing of Chinese herbal medicine powders and granules.

[0031] Example 2: Based on Example 1, such as Figure 1 , Figure 5 and Figure 6 As shown, a return mechanism 10 is provided between the particle return pipe 84 and the feeding frame 4. The return mechanism 10 includes: a cover plate 101, installed at the top annular opening of the feeding frame 4; an air outlet 102, installed on the cover plate 101, used to balance the air pressure inside the feeding frame 4; a connecting pipe 103, connected to the outlet of the particle return pipe 84, with the end of the connecting pipe 103 away from the particle return pipe 84 being closed; and a flexible hose 104, connected to the connecting pipe 104. Between pipe 103 and cover plate 101, hose 104 passes through cover plate 101 and extends into feeding frame 4. When three-way valve 91 is switched to connect feed pipe 82 and particle return pipe 84, the Chinese medicine particles screened by medicinal screen 93 are returned to feeding frame 4 using connecting pipe 103 and hose 104. This facilitates the secondary flow of Chinese medicine particles in feeding frame 4 to airflow pulverizing mechanism 6 for secondary crushing, so that the Chinese medicine dry material particles that have not been crushed to the standard are fully crushed.

[0032] like Figure 1 and Figure 8 As shown, it also includes a recycling mechanism 11, which includes: a collection tank 111, mounted on the base plate 1, with the top collection port of the collection tank 111 aligned with the outlet of the solenoid valve 5; a reflux pump 112, mounted on the base plate 1; a connecting pipe 113, connecting the collection tank 111 and the inlet of the reflux pump 112; and a fragment reflux pipe 114, one end of which is connected to the outlet of the reflux pump 112, and the other end of which is connected to the lower part of one side of the feeding frame 4. After the solenoid valve 5 is opened, the collection tank 111 collects the incompletely crushed Chinese herbal medicine fragments at the bottom of the processing tank 3, and then the reflux pump 112 removes the Chinese herbal medicine fragments inside the collection tank 111. The connecting pipe 113 and the fragment return pipe 114 guide the flow back to the feeding frame 4 for secondary feeding, so that the Chinese medicine fragments can also flow back into the airflow pulverizing mechanism 6 for secondary crushing, further improving the yield of the crushed Chinese medicine dry materials. The fragment return pipe 114 is a rigid pipe, and the fragment return pipe 114 is branched into two sections at the outlet pipe of the feeding frame 4. One section is horizontally connected to the lower side of the feeding frame 4, and the other section is inclined downwards and connected to the side of the feeding frame 4 near the bottom. The branched pipe of the fragment return pipe 114 helps the Chinese medicine fragments to disperse into the feeding frame 4, reducing the situation of the Chinese medicine fragments sticking together or causing blockage, and accelerating the rate of circulation crushing of the Chinese medicine fragments.

[0033] After the airflow enters the particle return pipe 84, the herbal particles mixed in the airflow will flow sequentially through the connecting pipe 103 and the hose 104, and finally return to the feeding frame 4. At this time, the air outlet 102 will discharge the gas continuously introduced into the feeding frame 4, while screening out the herbal particles in the airflow and continuously balancing the air pressure in the feeding frame 4. The herbal particles entering the feeding frame 4 will finally enter the feeding pipe 63 again, and be guided back to the guide pipe 62 through the feeding pipe 63. Driven by the high-speed airflow, they will be sprayed out from the high-pressure air pump 61 for secondary crushing. When a certain amount of incompletely crushed herbal fragments accumulate at the bottom of the processing tank 3, the high-pressure air pump 61 is temporarily shut off and the solenoid valve 5 is opened. These herbal fragments are discharged through the recovery port at the bottom of the processing tank 3. The incompletely crushed herbal fragments enter the collection tank 111 through the outlet of the solenoid valve 5. The reflux pump 112 is activated, and the Chinese herbal medicine fragments in the collection tank 111 are pumped to the fragment reflux pipe 114 through the connecting pipe 113. Finally, the Chinese herbal medicine fragments will also flow back from the fragment reflux pipe 114 to the feeding frame 4. Due to the bifurcated design of the fragment reflux pipe 114, one section is horizontally connected to the lower side of the feeding frame 4, and the other section is inclined downwards and connected to the side of the feeding frame 4 near the bottom. This helps the Chinese herbal medicine fragments to be evenly distributed in the feeding frame 4, reducing accumulation and blockage, and ensuring that the fragments can be evenly dispersed. The Chinese herbal medicine fragments entering the feeding frame 4 finally enter the guide pipe 62 through the feeding pipe 63, and are driven by the high-pressure airflow to be sprayed out through the discharge nozzle 64 for secondary crushing. Through the above process, the incompletely crushed Chinese herbal medicine particles and fragments are crushed multiple times until they reach the required fineness standard, thereby improving the crushing yield of dried Chinese herbal medicine materials.
