Description

Technical Field

[0001] The invention belongs to the technical field of biological medicine manufacturing, and in particular relates to a multifunctional integrated device for preparing Chinese herbal medicine slices. Background Art

[0002] The preparation of Chinese herbal medicines is an important part of traditional Chinese medicine. It refers to the process of processing Chinese medicinal materials according to drug properties and clinical treatment needs. Traditional preparation technology of Chinese herbal medicines mostly relies on manual operation, which is not only inefficient, but also difficult to ensure the consistency and stability of product quality. With the development of modern science and technology, people have higher and higher requirements on the quality of Chinese herbal medicines, and traditional methods can no longer meet the needs of modern production and market.

[0003] After searching, the patent with authorization announcement number CN112755129B discloses a processing equipment based on Chinese herbal medicine slices, including a motor, a top cover, a crushing cylinder, a discharge pipe, a feed hopper, an air flow distribution pipe, a feed pipe and a feed screw. The processing equipment also includes support legs, an air flow distribution pipe shock-absorbing assembly and heat dissipation fins. The processing equipment uses high-speed airflow to make materials collide with each other to achieve the purpose of crushing; however, the processing equipment still has certain limitations when used. When the material falls vertically through the air outlet, only the part of the material that first contacts the high-speed airflow can be effectively crushed, while the subsequent material may directly pass through the air flow area and fail to achieve the expected crushing effect. This not only reduces the processing efficiency, but may also lead to uneven product quality, especially for Chinese herbal medicine slices, which have high requirements on the fineness of raw materials and may affect the efficacy of the medicine. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a multifunctional integrated equipment for preparing Chinese herbal medicine slices.

[0005] The technical scheme of the present invention is: a multifunctional integrated equipment for preparing Chinese herbal medicine slices, comprising a bottom plate, a support seat and a preparation tank, wherein the bottom plate is fixedly connected to the support seat, the bottom plate and the support seat are load-bearing carriers of the equipment, the preparation tank is installed on the top of the support seat, the top of the preparation tank is provided with a discharge port for Chinese herbal medicine powder, the bottom of the preparation tank is provided with a recovery port for Chinese herbal medicine dry product debris, and the preparation tank is a container for preparing Chinese herbal medicine slices; and further comprising: a material discharge frame, which is arranged on the upper outer side of the preparation tank through a mounting block, the The material discharge frame is annular and surrounds the outer wall of the processing tank, the lower part of the material discharge frame is a smaller material guide port, and the bottom of the material discharge frame is a material discharge port; the installation frame is arranged at the lower part of the inner wall of the material discharge frame, and the installation frame is an annular frame body surrounding and fixedly connected to the lower inner wall of the material discharge frame; the electromagnetic valve is installed on the top of the support seat, and the electromagnetic valve is located at the recovery port at the bottom of the processing tank; the airflow crushing mechanism is arranged on the top surface of the support seat and is used to spray and crush the dry Chinese medicine material in the processing tank; the airflow crushing mechanism includes The invention is summarized as follows: a high-pressure air pump, which is provided with a plurality of them and is circumferentially installed on the top surface of the support seat with the preparation tank as the center; a plurality of guide pipes, the number of which is consistent with the high-pressure air pump and one end of which is sealed and connected to the lower side wall of the preparation tank, and the pipe openings of the two symmetrical guide pipes are facing each other, and the other end of the guide pipe is connected to the air outlet of the high-pressure air pump; a feed pipe, one end of which is connected to the feed opening at the bottom of the feed frame, and the other end of the feed pipe is connected to the inside of the guide pipe; a discharge nozzle is installed at the air outlet of each guide pipe, The discharging nozzles are circumferentially distributed in the lower part of the processing tank, and the discharging nozzles are used to utilize high-speed airflow to make materials collide with each other to achieve crushing; the discharging piece is arranged in the discharging pipe, and the discharging piece is used to assist the dry Chinese medicine materials in the discharging frame to be regularly guided into the guide pipe to avoid too much material falling into the guide pipe in a short time, which may cause the dry Chinese medicine materials to be easily blocked in the guide pipe, so that the discharging nozzle only sprays out an appropriate amount of dry Chinese medicine materials at a high speed at a time, so that the dry Chinese medicine materials can be effectively crushed into powder raw materials for Chinese herbal medicine slices under the high-speed airflow.

[0006] Furthermore, the processing tank is in the shape of a truncated cone which is wider at the top and narrower at the bottom. The discharge port at the top of the processing tank is an opening for collecting the processed powder. The processing tank which is wider at the top and narrower at the bottom can reduce the resistance of the airflow entering the tank, so that the airflow drives the crushed Chinese medicine powder to be discharged more smoothly through the discharge port of the processing tank. At the same time, the Chinese medicine dry product residue that is not fully crushed sinks to the bottom of the processing tank. The discharge nozzles are all circumferentially arranged inside the processing tank and form a circle, and the two opposite discharge nozzles are facing each other. The nozzle of the discharge nozzle is smaller than the diameter of the guide tube, and the nozzle of the discharge nozzle is slightly larger than the crushed Chinese medicine dry product material. When the high-speed airflow enters the discharge nozzle from the guide tube, the smaller flow diameter can further accelerate the speed of the airflow, so that the high-speed airflow can drive the Chinese medicine dry product material to collide at high speed to achieve effective crushing.

[0007] Furthermore, the material discharge part includes: a servo motor, which is symmetrically installed in the installation frame, and the output shaft of the servo motor penetrates the installation frame and then extends into the upper tube of the material discharge pipe; a spiral feed roller, which is installed on the output shaft of the servo motor, and the spiral feed roller is located in the upper tube body of the material discharge pipe, and the spacing between the conveying threads of the spiral feed roller is the distance for conducting a single Chinese herbal medicine material; a funnel, which is arranged in the lower tube body of the material discharge pipe; a check valve, which is installed at the lower leakage port of the funnel, and the check valve is a unidirectional conduction of the funnel from top to bottom. The spiral feed roller is driven by the servo motor to rotate at the top tube port of the material discharge pipe, so that the Chinese herbal medicine material leaking from the material discharge port of the material discharge frame can be conveyed by the spiral feed roller and fall into the funnel in a quantitative manner in sequence, and finally enter the guide tube from the check valve, and finally follow the high-speed airflow in the guide tube to be sprayed out from the discharge nozzle.

[0008] Furthermore, a diversion mechanism is provided on the top of the processing tank, and the diversion mechanism includes: a diversion pipe, which is arranged at the discharge port on the top of the processing tank, and the diversion pipe is a three-way pipe and is used to divert the Chinese medicine powder and Chinese medicine particles that rise with the airflow after being crushed; a feeding pipe, which is connected to the opening at the lower part of the diversion pipe, and the feeding pipe is connected to the discharge port at the top of the processing tank; a powder collecting pipe, which is connected to the opening on one side of the upper part of the diversion pipe, and the powder collecting pipe is a collection channel for Chinese medicine powder; a particle reflux pipe, which is connected to the opening on the other side of the upper part of the diversion pipe, and the particle reflux pipe is a recovery channel for Chinese medicine particles; a switching member, which is arranged at the intersection of the three-way opening inside the diversion pipe, and the switching member is used to switch the powder collecting pipe or the particle reflux pipe, so that the powder collecting pipe or the particle reflux pipe can be connected to the feeding pipe respectively, so that the Chinese medicine powder and Chinese medicine particles can flow into the powder collecting pipe and the particle reflux pipe respectively, so as to conveniently and directly collect the Chinese medicine powder and recycle the Chinese medicine particles.

[0009] Furthermore, the switching component includes: a three-way valve, which is sealed and rotatably installed at the intersection of the three-way ports inside the shunt pipe, the three-way valve is a cylinder and has openings in three directions, the openings of the three-way valve are vertically crossed, and when the adjacent vertical openings of the three-way valve are connected, the opening of the remaining one will be in a blocked and closed state; a mounting shaft, which is fixed to one side of the three-way valve, and the mounting shaft rotates to penetrate the side wall of the shunt pipe; a medicinal screen, which is arranged at one of the openings facing the three-way valve, and the medicinal screen is used to separate the medicinal sieve in the gas at the feed pipe. Chinese medicine powder and Chinese medicine granules; a stepper motor is installed on the outer wall of the shunt pipe, the output shaft of the stepper motor is connected to the installation shaft, the stepper motor drives the three-way valve to rotate in the shunt pipe through the installation shaft, and the stepper motor can drive the three-way valve to rotate 180 degrees at a preset angle, so that the three-way valve can connect the feed pipe and the powder collection pipe, or connect the feed pipe and the granule reflux pipe, and when the feed pipe and the powder collection pipe are connected, the medicinal screen will block the feed pipe, so that the Chinese medicine powder and Chinese medicine granules in the airflow can be sieved.

[0010] Furthermore, a reflux mechanism is provided between the particle reflux pipe and the discharge frame, and the reflux mechanism includes: a cover plate installed at the top annular opening of the discharge frame; an air outlet sieve port installed on the cover plate, and the air outlet sieve port is used to balance the air pressure in the discharge frame; a butt joint pipe connected to the outlet of the particle reflux pipe, and the end of the butt joint pipe away from the particle reflux pipe is closed; a hose connected between the butt joint pipe and the cover plate, and the hose penetrates the cover plate and extends into the discharge frame. When the three-way valve is switched to connect the feed pipe and the particle reflux pipe, the butt joint pipe and the hose are used to return the Chinese medicine particles screened by the medicinal sieve to the discharge frame, so as to facilitate the subsequent secondary diversion of the Chinese medicine particles in the discharge frame to the air flow pulverizing mechanism for secondary crushing, so that the Chinese medicine dry material particles that fail to meet the crushing standards can be fully crushed.

[0011] Furthermore, it also includes a recycling mechanism, which includes: a collecting tank, which is arranged on the bottom plate, and the top collecting port of the collecting tank is aligned with the outlet of the solenoid valve; a reflux pump, which is installed on the bottom plate; a connecting pipe, which is connected between the collecting tank and the inlet of the reflux pump; a fragment reflux pipe, one end of which is connected to the outlet of the reflux pump, and the other end of the fragment reflux pipe is connected to the lower part of one side of the discharge frame. After the solenoid valve is opened, the completely crushed Chinese medicine fragments at the bottom of the preparation tank are collected by the collecting tank, and then the Chinese medicine fragments in the collecting tank are guided back to the discharge frame through the connecting pipe and the fragment reflux pipe for secondary discharge through the reflux pump, so that the Chinese medicine fragments can also flow back to the airflow crushing mechanism for secondary crushing, thereby further improving the yield of the crushing of the Chinese medicine dry material.

[0012] Furthermore, the fragment reflux pipe is a hard pipe, and the fragment reflux pipe is bifurcated into two sections at the outlet pipe body connected to the discharge frame, one section is horizontally connected to the lower side of the discharge frame, and the other section is inclined downward to connect to the side of the discharge frame near the bottom. The bifurcated pipe body of the fragment reflux pipe helps the Chinese medicine fragments to disperse into the discharge frame, reduces the situation where the Chinese medicine fragments are pushed together or cause blockage, and accelerates the rate of circulation and crushing of the Chinese medicine fragments.

[0013] The beneficial effects of the present invention are: 1. The present invention adopts the design of a high-pressure air pump and a guide pipe, and cooperates with a feed pipe to be connected to the guide pipe, so that the airflow forms a high-speed collision in the processing tank, effectively promoting the mutual collision of materials and improving the crushing efficiency. The servo motor drives the spiral feeding roller to make the dry Chinese medicine materials enter the guide pipe regularly, avoiding blockage of the guide pipe, ensuring that an appropriate amount of material is sprayed out each time to improve the crushing effect.

[0014] 2. The present invention can guide the crushed Chinese medicine powder and particles to the powder collection pipe and the particle reflux pipe respectively through the shunt pipe and the three-way valve, ensuring that only the Chinese medicine powder reaching the specified particle size is collected, and the particles that do not reach the standard are recycled and processed, thereby improving the particle size uniformity of the final product.

[0015] 3. The present invention uses a particle reflux pipe to return substandard Chinese medicine particles to the feed frame for secondary feeding and crushing, ensuring that all materials can be fully crushed and improving the yield. At the same time, the incompletely crushed Chinese medicine fragments at the bottom of the preparation tank are collected through a fragment reflux pipe and re-introduced into the feed frame for secondary crushing, further improving the utilization rate of the materials.

The processing tank 3 is a container for processing Chinese medicine pieces; it also includes: a feeding frame 4, which is arranged on the upper outer side of the processing tank 3 through a mounting block 41. The feeding frame 4 is annular and surrounds the outer wall of the processing tank 3. The bottom of the feeding frame 4 The lower part is a smaller material guide port, and the bottom of the feeding frame 4 is a feeding port; the mounting frame 42 is arranged at the lower part of the inner wall of the feeding frame 4, and the mounting frame 42 is an annular frame body that surrounds and is fixed to the lower inner wall of the feeding frame 4; the electromagnetic valve 5 is installed on the top of the support seat 2, and the electromagnetic valve 5 is located at the recovery port at the bottom of the processing tank 3; the air flow crushing mechanism 6 is arranged on the top surface of the support seat 2 and is used to spray and crush the dry Chinese medicine materials in the processing tank 3; the air flow crushing mechanism 6 includes: a high-pressure air pump 61, which is provided with a plurality of and is circumferentially arranged around the processing tank 3 Installed on the top surface of the support seat 2; multiple guide pipes 62, the number of which is consistent with the high-pressure air pump 61 and one end of which is sealed and connected to the lower side wall of the processing tank 3, the pipe openings of the two symmetrical guide pipes 62 are facing each other, and the other end of the guide pipe 62 is connected to the air outlet of the high-pressure air pump 61; a feed pipe 63, one end of which is connected to the feed opening at the bottom of the feed frame 4, and the other end of the feed pipe 63 is connected to the guide pipe 62; a discharge nozzle 64, installed at the air outlet of each guide pipe 62, and multiple discharge nozzles 64 are circumferentially distributed in the processing tank 3. In the lower part of the tank 3, the discharge nozzle 64 is used to utilize high-speed airflow to make the materials collide with each other to achieve crushing; the discharge piece 7 is arranged in the discharge pipe 63, and the discharge piece 7 is used to assist the dry Chinese medicine materials in the discharge frame 4 to be regularly guided to the guide pipe 62, so as to avoid too much material falling into the guide pipe 62 in a short time, which may cause the dry Chinese medicine materials to be easily blocked in the guide pipe 62, so that the discharge nozzle 64 only sprays out an appropriate amount of dry Chinese medicine materials at a high speed at a time, so that the dry Chinese medicine materials can be effectively crushed into powder raw materials for Chinese herbal medicine slices under the high-speed airflow.

[0027] like Figure 2 and Figure 3As shown, the processing tank 3 is in the shape of a truncated cone which is wide at the top and narrow at the bottom. The discharge port 31 at the top of the processing tank 3 is an opening for collecting the processed powder. The processing tank 3 which is wide at the top and narrow at the bottom can reduce the resistance of the airflow entering the tank, so that the airflow drives the crushed Chinese medicine powder to be discharged more smoothly through the discharge port 31 of the processing tank 3. At the same time, the Chinese medicine dry product residue that is not fully crushed sinks to the bottom of the processing tank 3. The discharge nozzles 64 are all circumferentially arranged inside the processing tank 3 and form a circle, and the two opposite discharge nozzles 64 are facing each other. The nozzle of the discharge nozzle 64 is smaller than the diameter of the guide tube 62, and the nozzle of the discharge nozzle 64 is slightly larger than the crushed Chinese medicine dry product material. When the high-speed airflow enters the discharge nozzle 64 from the guide tube 62, the smaller flow diameter can further accelerate the speed of the airflow, so that the high-speed airflow can drive the Chinese medicine dry product material to collide at high speed to achieve effective crushing.

[0028] like Figure 3 and Figure 4 As shown, the material discharge part 7 includes: a servo motor 72, which is symmetrically installed in the installation frame 42, and the output shaft of the servo motor 72 penetrates the installation frame 42 and then extends into the upper tube of the material discharge pipe 63; a spiral feed roller 71, which is installed on the output shaft of the servo motor 72, and the spiral feed roller 71 is located in the upper tube body of the material discharge pipe 63, and the spacing between the conveying threads of the spiral feed roller 71 is the distance for conducting a single Chinese medicine dry product material; a funnel 73, which is arranged in the lower tube body of the material discharge pipe 63; a stopper The check valve 74 is installed at the lower leakage port of the funnel 73. The check valve 74 is a unidirectional guide from top to bottom for the funnel 73. The servo motor 72 drives the spiral feed roller 71 to rotate at the top pipe port of the discharge pipe 63, so that the dry Chinese medicine materials leaking from the discharge port of the discharge frame 4 can be transported by the spiral feed roller 71 and fall into the funnel 73 in sequence and quantitatively, and finally enter the guide pipe 62 from the check valve 74, and finally follow the high-speed airflow in the guide pipe 62 to be ejected from the discharge nozzle 64.

[0029] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, a diversion mechanism 8 is provided on the top of the processing tank 3, and the diversion mechanism 8 includes: a diversion pipe 81, which is arranged at the discharge port 31 on the top of the processing tank 3, and the diversion pipe 81 is a three-way pipe and is used to divert the Chinese medicine powder and Chinese medicine particles that rise with the air flow after being crushed; a feed pipe 82, which is connected to the opening at the lower part of the diversion pipe 81, and the feed pipe 82 is connected to the discharge port 31 on the top of the processing tank 3; a powder collection pipe 83, which is connected to a side opening at the upper part of the diversion pipe 81, and the powder collection pipe 83 is a collection channel for Chinese medicine powder; a particle reflux pipe 84, which is connected to the diversion pipe At the other side opening of the upper part of the tube 81, the particle reflux pipe 84 is a recovery channel for the Chinese medicine particles; the switching member 9 is arranged at the intersection of the three-way opening inside the shunt tube 81, and the switching member 9 is used to switch the powder collection pipe 83 or the particle reflux pipe 84, so that the powder collection pipe 83 or the particle reflux pipe 84 can be connected to the feed pipe 82 respectively, so that the Chinese medicine powder and the Chinese medicine particles can flow into the powder collection pipe 83 and the particle reflux pipe 84 respectively, so as to conveniently and directly collect the Chinese medicine powder and recycle the Chinese medicine particles; the switching member 9 includes: a three-way valve 91, which is sealed and rotatably installed on the shunt tube 8 1 is at the intersection of the three-way ports inside, the three-way valve 91 is a cylinder with openings in three directions, the openings of the three-way valve 91 are vertically crossed, when the adjacent vertical openings of the three-way valve 91 are connected, the opening of the remaining one will be in a blocked and closed state; the mounting shaft 92 is fixed to one side of the three-way valve 91, and the mounting shaft 92 rotates to penetrate the side wall of the shunt pipe 81; the medicinal screen 93 is set at one of the openings of the three-way valve 91 facing each other, and the medicinal screen 93 is used to separate the Chinese medicine powder and Chinese medicine particles in the gas at the feeding pipe 82; the stepping motor 94 is installed on the shunt pipe 8 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 shunt pipe 81 through the mounting shaft 92, and the stepper motor 94 can drive the three-way valve 91 to rotate by 180 degrees according to the preset value, so that the three-way valve 91 can connect the feed pipe 82 with the powder collection pipe 83, or connect the feed pipe 82 with the particle return pipe 84, and when the feed pipe 82 and the powder collection pipe 83 are connected, the medicinal screen 93 will be blocked at the feed pipe 82, so that the Chinese medicine powder and Chinese medicine particles in the airflow are screened.

[0030] When using the present device to process the powder raw materials of Chinese herbal medicine slices, firstly, the high-pressure air pump 61 on the support seat 2 is synchronously activated, and then the dry Chinese herbal medicine materials to be processed are placed in the feeding frame 4. Since the feeding frame 4 surrounds the outer wall of the processing tank 3, its bottom is designed as a smaller material guide port to ensure that the materials can fall into the feeding pipe 63 evenly and orderly. A spiral feeding roller 71 is installed inside the feeding pipe 63 and is driven by a servo motor 72. The materials are regularly introduced into the guide pipe 62 by rotation. In this process, the conveying thread pitch of the spiral feeding roller 71 is precisely set to ensure that only an appropriate amount of materials are conveyed each time, avoiding the blockage problem caused by excessive materials in the guide pipe 62. Since a check valve 74 is provided at the funnel 73 in the feeding pipe 63, The airflow in the guide tube 62 cannot flow into the discharge tube 63 and can only be sprayed out from the discharge nozzle 64. When the material passes through the funnel 73 and the check valve 74, it will enter the guide tube 62, driven by the high-speed airflow generated by the high-pressure air pump 61, and sprayed out through the discharge nozzle 64. Under the action of the high-speed airflow, the material collides at high speed in the processing tank 3 and is initially crushed. Since the processing tank 3 is in the shape of a truncated cone with a wide top and a narrow bottom, the resistance of the airflow entering the processing tank 3 is reduced, so that the crushed Chinese medicine powder can be discharged more smoothly through the discharge port 31 on the top of the processing tank 3. At the same time, the Chinese medicine dry product residue that is not fully crushed will sink to the bottom of the processing tank 3. Since the discharge nozzle 64 is circumferentially distributed inside the processing tank 3, and the two opposite discharge nozzles 64 The two valves are arranged in opposite directions to further enhance the crushing effect of the material. When the crushed material rises to the top of the processing tank 3 with the air flow, the three-way valve 91 in the shunt pipe 81 is in a state of being connected to the feed pipe 82 and the powder collecting pipe 83. The Chinese medicine powder and Chinese medicine particles floating from the discharge port 31 at the top of the processing tank 3 are separated by the medicinal screen 93. The Chinese medicine powder can pass through the medicinal screen 93 and enter the powder collecting pipe 83 for the convenience of collection by the user, while the Chinese medicine particles that do not meet the standards will be screened by the medicinal screen 93. After the initial Chinese medicine dry product material inside the discharge frame 4 is initially crushed in the processing tank 3 and the amount of Chinese medicine powder collected in the powder collecting pipe 83 is significantly reduced, most of the Chinese medicine particles and debris are mixed in the air flow in the processing tank 3 at this time. At this time, 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 in the shunt pipe 81, so that the three-way valve 91 in the shunt pipe 81 is in a state of being connected to the feed pipe 82 and the particle return pipe 84, and the opening of the three-way valve 91 with the medicinal screen 93 will be rotated and adjusted to the top of the inner wall of the shunt pipe 81, so that the medicinal screen 93 is no longer in the feed pipe 82. At this time, the upward airflow continues to drive most of the Chinese medicine particles therein to flow into the particle return pipe 84, so as to carry out subsequent recovery and processing operations on the Chinese medicine particles. Therefore, the stepper motor 94 controls the three-way valve 91 to perform cyclic switching in the shunt pipe 81, so that the crushed Chinese medicine powder and Chinese medicine particles in the processing tank 3 are diverted.This makes it easier to collect and reflux crush Chinese medicine powder and granules.

[0031] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 5 and Figure 6 As shown, a reflux mechanism 10 is provided between the particle reflux pipe 84 and the material discharging frame 4, and the reflux mechanism 10 comprises: a cover plate 101, which is installed at the annular opening at the top of the material discharging frame 4; an air outlet sieve 102, which is installed on the cover plate 101, and the air outlet sieve 102 is used to balance the air pressure in the material discharging frame 4; a butt joint pipe 103, which is connected to the outlet of the particle reflux pipe 84, and the end of the butt joint pipe 103 away from the particle reflux pipe 84 is closed; a hose 104, which is connected to the butt joint pipe 103. Between the tube 103 and the cover plate 101, the hose 104 penetrates the cover plate 101 and extends into the unloading frame 4. When the three-way valve 91 is switched to connect the feed pipe 82 and the particle return pipe 84, the docking tube 103 and the hose 104 are used to return the Chinese medicine particles screened by the medicinal screen 93 to the unloading frame 4, so as to facilitate the subsequent secondary diversion of the Chinese medicine particles in the unloading frame 4 to the air flow pulverizing mechanism 6 for secondary crushing, so that the Chinese medicine dry material particles that fail to meet the crushing standards can be fully crushed.

[0032] like Figure 1 and Figure 8 As shown, it also includes a recovery mechanism 11, which includes: a collecting tank 111, which is arranged on the bottom plate 1, and the top collecting port of the collecting tank 111 is aligned with the outlet of the electromagnetic valve 5; a reflux pump 112, which is installed on the bottom plate 1; a connecting pipe 113, which is connected between the collecting tank 111 and the inlet of the reflux pump 112; a fragment reflux pipe 114, one end of which is connected to the outlet of the reflux pump 112, and the other end of the fragment reflux pipe 114 is connected to the lower part of one side of the feeding frame 4. After the electromagnetic valve 5 is opened, the Chinese medicine fragments that are not completely crushed at the bottom of the processing tank 3 are collected by the collecting tank 111, and then the Chinese medicine fragments inside the collecting tank 111 are removed by the reflux pump 112. The connecting pipe 113 and the fragment return pipe 114 are guided back to the unloading frame 4 for secondary unloading, so that the Chinese medicine fragments can also flow back to the air flow crushing mechanism 6 for secondary crushing, further improving the yield of the Chinese medicine dry material crushing; the fragment return pipe 114 is a hard pipe, and the fragment return pipe 114 is connected to the outlet pipe body of the unloading frame 4 and is bifurcated into two sections, one of which is horizontally connected to the lower side of the unloading frame 4, and the other section is inclined downward to connect to the side of the unloading frame 4 near the bottom. The bifurcated pipe body of the fragment return pipe 114 helps the Chinese medicine fragments to be dispersed into the unloading frame 4, reduces the situation where the Chinese medicine fragments are pushed or blocked, and speeds up the rate of cyclic crushing of the Chinese medicine fragments.

[0033] After the airflow enters the particle reflux pipe 84, the Chinese medicine particles mixed in the airflow will flow through the docking pipe 103 and the hose 104 in sequence, and finally flow back to the feeding frame 4. At this time, the air outlet sieve port 102 will discharge the gas continuously introduced into the feeding frame 4, and at the same time screen the Chinese medicine particles in the airflow, and continuously balance the air pressure in the feeding frame 4. The Chinese medicine 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, and be ejected from the high-pressure air pump 61 for secondary crushing under the drive of the high-speed airflow. When a certain amount of incompletely crushed Chinese medicine fragments accumulate at the bottom of the processing tank 3, the high-pressure air pump 61 is temporarily closed and then the solenoid valve 5 is opened. These Chinese medicine fragments are discharged through the recovery port at the bottom of the processing tank 3, and the incompletely crushed Chinese medicine fragments enter the collecting tank 111 through the outlet of the solenoid valve 5. Finally, The reflux pump 112 is activated to pump the Chinese medicine fragments in the collection tank 111 to the fragment reflux pipe 114 through the connecting pipe 113, and finally the Chinese 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 tilted downward to connect to the side of the feeding frame 4 near the bottom, which helps to evenly distribute the Chinese medicine fragments in the feeding frame 4 to reduce accumulation and blockage, ensuring that the fragments can be evenly dispersed. The Chinese 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 ejected through the discharge nozzle 64 for secondary crushing. Through the above process, the Chinese medicine particles and Chinese medicine fragments that are not completely crushed are crushed after multiple cycles until the required fineness standard is reached, thereby improving the crushing yield of the Chinese medicine dry material.
