[0002] Traditional Chinese medicinal herbs (such as Prunella vulgaris) often contain impurities such as sand, mud, and dust. If these are not purified before use and are only washed, the process is time-consuming and water-intensive, and can easily lead to the loss of active ingredients. Furthermore, other impurities may enter the product, affecting its quality. Therefore, it is necessary to purify the Prunella vulgaris raw material before extraction. Since the raw materials are delivered in compressed bundles, they must be broken up and dispersed before purification can begin. Utility Model Content

[0016] As an optional embodiment, a second material leveling component is provided between the discharge end of the second conveying component and the inlet of the air duct. The second material leveling component is used to make the material entering the inlet evenly distributed.

[0017] As an optional embodiment, the herbal medicine purification device further includes an electrical control box, which is connected to the splitting component, the first dust suction component, the first conveying component, the second dust suction component, the second conveying component and the air separator, respectively, to control the opening and closing of each component.

[0018] The beneficial effects of the embodiments of this application are as follows:

[0019] This application breaks down bundled Chinese herbal medicines into flake or block material units by disassembling components, reducing the workload of the subsequent dispersing machine; before air separation, two dust collection processes are carried out to remove most of the dust and light impurities, effectively reducing the workload of the air separator, ensuring the stable operation of each piece of equipment, and improving the overall processing efficiency.

[0033] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0034] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0035] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0036] This application provides an embodiment of a traditional Chinese medicine purification device, such as... Figure 1 As shown, it includes a splitting component 1, a first dust collection component 2, a first conveying component 3, a second dust collection component 4, a second conveying component 5, and an air separator 6.

[0037] The splitting component 1 includes a splitting element 14, which is used to split bundles of Chinese herbal medicines into sheet-like or block-like material units.

[0038] The first dust collection component 2 is disposed on the splitting component 1 and is used to remove the first impurities carried by the Chinese herbal medicine before splitting. The first dust collection component 2 includes a dust collection hood and a fan 64 disposed above the splitting component 1. Its specific structure and working principle are prior art and will not be described in detail in this application.

[0039] The feeding end of the first conveying component 3 is connected to the discharging end of the splitting component 1. The first conveying component 3 is provided with a dispersing component 33, which is used to disperse the material unit into discrete materials.

[0040] The second dust collection component 4 is disposed on the first conveying component 3 and is used to remove the first impurities generated when the material unit is broken up. The second dust collection component 4 includes a dust collection hood and a fan 64 disposed above the first conveying component 3. Its specific structure and working principle are prior art and will not be described in detail in this application.

[0041] The feeding end of the second conveying component 5 is connected to the discharging end of the first conveying component 3, and is used to convey the discrete materials.

[0042] The inlet of the air classifier 6 is connected to the outlet of the second conveying assembly 5. The air classifier 6 includes an impurity outlet 61 and multiple outlets 62. The air classifier 6 performs air classification on the discrete material so that the second impurity in the discrete material falls out from the impurity outlet 61 and the air-classified discrete material falls out through the outlets 62. The specific gravity of the first impurity is less than that of the second impurity.

[0043] In this embodiment, taking Prunella vulgaris as an example, bundles of Prunella vulgaris are split into flakes or small pieces by the splitting component 1. Before splitting, the first dust suction component 2 removes dust and other first impurities attached to the surface of Prunella vulgaris.

[0044] Then it is broken up on the first conveying component 3, and the dust and other first impurities generated during the breaking up process are sucked up by the second dust collection component 4.

[0045] Next, the dispersed Prunella vulgaris enters the air separator 6 through the second conveying component 5. The air separator 6 separates out the second impurities with a larger specific gravity, such as soil and sand. The air-separated Prunella vulgaris comes out from the discharge port 62.

[0046] This application reduces the workload of the subsequent dispersing machine by splitting component 1, thereby improving the dispersing effect and the cleanliness of the raw materials. After two stages of dust extraction, most of the lighter impurities are removed, reducing the workload of the air classifier 6 and improving the air classification efficiency. The air classifier 6 separates impurities based on their specific gravity, effectively removing heavier impurities and improving the purity of the Chinese herbal medicines.

[0047] In one embodiment, such as Figure 2As shown, the splitting assembly 1 also includes a frame 11, a conveyor belt 12, and a robotic arm 13. The conveyor belt 12 and the robotic arm 13 are mounted on the frame 11. The robotic arm 13 is positioned corresponding to the discharge end of the conveyor belt 12. The robotic arm 13 is equipped with multiple splitting components 14 facing the conveyor belt 12. The multiple splitting components 14 move closer to or further away from the conveyor belt 12 under the action of the robotic arm 13 to split the bundled Chinese herbal medicines.

[0048] In this embodiment, bundles of Chinese herbal medicines are placed on the conveyor belt 12 of the frame 11. The conveyor belt 12 transports them to the discharge end. A robotic arm 13 moves multiple splitting components 14 close to the conveyor belt 31 to split the bundles of Chinese herbal medicines. After splitting, the robotic arm 13 moves the splitting components 14 away from the conveyor belt 31. For example, for bundles of Prunella vulgaris, they are placed on the conveyor belt 12, which transports them to a designated position. The robotic arm 13 descends, and the splitting components 14 insert into the bundles of Prunella vulgaris, splitting them into flakes or blocks.

[0049] This application achieves automated conveying of bundled Chinese herbal medicines via conveyor belt 12, improving work efficiency. The robotic arm 13 drives the splitting component 14 to split the bundles, offering flexible operation and enabling rapid splitting of the bundled Chinese herbal medicines.

[0050] In one embodiment, such as Figure 3 As shown, the splitting component 14 includes a splitting rod 141 and a reinforcing rod 142. One end of the splitting rod 141 is connected to the robotic arm 13, and the other end is inclined in the material feeding direction and connected to one end of the reinforcing rod 142. The reinforcing rod 142 and the splitting rod 141 are arranged in a V-shape.

[0051] In this embodiment, after the bundled Chinese herbal medicines are transported to the designated position by the conveyor belt 12, the robotic arm 13 drives the splitting component 14 to move closer to the conveyor belt 31.

[0052] At this point, the splitting rod 141, tilted towards the incoming material, is inserted into the bundle of Chinese herbal medicines. Because the splitting rod 141 and the reinforcing rod 142 are arranged in a V-shape, the reinforcing rod 142 acts like a barb. During the splitting process, the reinforcing rod 142 enhances the structural stability of the splitting rod 141, making it less prone to deformation under large splitting forces, ensuring continuous and stable splitting operations. Furthermore, as the splitting rod 141 splits the bundle of Chinese herbal medicines, when the robotic arm 13 moves the splitting rod 141, the reinforcing rod 142 pushes the already split sheet-like or block-like material units towards the first conveying component 3, facilitating the smoother separation of these material units from the splitting area and preparing them for subsequent conveying and processing.

[0053] Specifically, bundles of Prunella vulgaris are placed on conveyor belt 12 and transported below robotic arm 13. Robotic arm 13 descends, and splitting rod 141 inserts into the bundles of Prunella vulgaris. During the splitting process, reinforcing rod 142 not only stabilizes the splitting rod 141, preventing it from bending and deforming under the resistance of the Prunella vulgaris stems, but also, as the robotic arm 13 moves the splitting rod 141 away from conveyor belt 12, pushes the already split Prunella vulgaris leaves and small stem segments towards the first conveying assembly 3, allowing them to fall smoothly onto the first conveying assembly 3 for subsequent processing.

[0054] The V-shaped splitting rod 141 and reinforcing rod 142 in this application greatly enhance the overall strength of the splitting component 14. When splitting bundles of Chinese herbal medicines, the splitting component 14 often needs to withstand significant forces, especially when encountering bundles of herbs that are hard or tightly bound. The presence of the reinforcing rod 142 acts like adding a stable support structure to the splitting rod 141, effectively distributing the force, reducing the risk of deformation of the splitting rod 141, extending the service life of the splitting component 14, and reducing equipment maintenance and replacement costs due to damage to the splitting component 14.

[0055] The reinforcing rod 142 also has the function of pushing the split materials to one side, optimizing the material conveying process. The split materials can be transferred from the splitting area to the first conveying component 3 in a more orderly manner, avoiding the accumulation of materials in the splitting area, ensuring the continuity and smoothness of the entire purification process, and improving production efficiency.

[0056] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the first conveying assembly 3 further includes a conveyor belt 31 and baffles 32 disposed on opposite sides of the conveyor belt 31. The dispersing component 33 includes a fixing part 331 and a dispersing part 332. The fixing part 331 is connected to the baffle 32. One end of the dispersing part 332 is connected to the fixing part 331. The other end of the dispersing part 332 has a notch 333 near the material feeding direction. The notch 333 is located above the conveyor belt 31 of the first conveying assembly 3.

[0057] In this embodiment, during the purification process of traditional Chinese medicine, the material units, which are broken down into sheet or block shapes by the splitting component 1, are conveyed onto the conveyor belt 31 of the first conveying component 3. Baffles 32 are provided on both sides of the conveyor belt 31 of the first conveying component 3 to prevent the material from falling off during conveying and to ensure that the material moves stably forward along the conveyor belt 31.

[0058] When the material unit moves with the conveyor belt 31 to the location of the dispersing component 33, the dispersing component 33 fixed on the baffle 32 begins to function. The material unit enters the gap 333 area under the drive of the conveyor belt 31, and the dispersing part 332 performs a moderate dispersing operation on the material unit.

[0059] Due to this special structural design, the dispersing section 332 can disperse materials into discrete materials in a relatively gentle manner, avoiding excessive impact and compression, thereby reducing the breakage of materials.

[0060] Specifically, when the material units formed after disassembly reach the dispersing unit 33, they enter the dispersing area through the notch 333 of the dispersing section 332. The dispersing section 332 disperses the Prunella vulgaris with appropriate force and method, breaking it into a discrete state, but without excessively breaking it into small fragments due to violent impact and tearing, as some traditional dispersing equipment does. In this way, most of the Prunella vulgaris can maintain a relatively intact shape, facilitating subsequent processing and utilization.

[0061] The dispersing component 33 of this application, by setting a notch 333, can avoid indiscriminate and high-intensity impact on materials compared with some ordinary dispersing equipment, thereby effectively reducing the crushing of Prunella vulgaris raw materials.

[0062] In one embodiment, such as Figure 1 As shown, the second conveying component 5 is inclined on one side of the first conveying component 3, and the discharge end of the first conveying component 3 is provided with a feed hopper 7 so that the discrete material falls onto the second conveying component 5 through the feed hopper 7.

[0063] In this embodiment, the first conveying component 3 conveys the discrete material to the discharge end, and the discrete material falls onto the inclined second conveying component 5 through the feed hopper 7. The second conveying component 5 then conveys the discrete material to the air classifier 6.

[0064] This application ensures that discrete materials fall accurately onto the second conveying assembly 5 via the feed hopper 7, preventing material spillage. The inclined arrangement of the second conveying assembly 5 facilitates material conveying and reduces the space occupied in the horizontal direction.

[0065] In one embodiment, such as Figure 1 As shown, a first material leveling component 8 is provided on one side of the second conveying component 5. The first material leveling component 8 is used to make the material fed into the air classifier 6 through the second conveying component 5 evenly distributed.

[0066] In this embodiment, the first material leveling component 8 includes a motor, a belt drive, a material leveling roller, and a material leveling plate. The motor is connected to the belt drive, the driven wheel of the belt drive is connected to the material leveling roller, and the material leveling roller is provided with multiple material leveling plates.

[0067] The motor's operation causes its output shaft to drive the belt-driven drive wheel to rotate. The rotation of the drive wheel is transmitted to the driven wheel via the belt, thereby causing the material leveling roller connected to the driven wheel to start rotating.

[0068] When the discrete material is conveyed to the area of ​​the first leveling component 8 through the second conveying component 5, the rotating leveling roller causes the leveling plate to come into contact with the material. The rotation of the leveling plate stirs and disperses the material, initially breaking up and dispersing the material that may have piled up or been unevenly distributed, making the material more evenly distributed to a certain extent.

[0069] This application uses the first uniform material distribution component 8 to make the material entering the air classifier 6 evenly distributed, thereby improving the air classification effect of the air classifier 6 and avoiding uneven air classification due to material accumulation.

[0070] In one embodiment, such as Figure 1 As shown, the air classifier 6 also includes an inclined air duct 63 and a fan 64. The air duct 63 is provided with an inlet near the discharge end of the second conveying component 5, and the impurity outlet 61 is provided on the air duct 63 away from the discharge end of the second conveying component 5.

[0071] In this embodiment, discrete materials enter the air separator 6 from the feed inlet of the air duct 63 through the second conveying component 5. The fan 64 generates air force. In the inclined air duct 63, the material and impurities are separated by a different specific gravity, causing the second impurity with a larger specific gravity to fall out from the impurity outlet 61. The material continues to move in the air duct 63.

[0072] The inclined air duct 63 design of this application facilitates the separation of materials and impurities, improving air classification efficiency. The blower 64 provides airflow, ensuring the smooth operation of the air classification process.

[0073] In one embodiment, such as Figure 1 As shown, a second material leveling component 9 is provided between the discharge end of the second conveying component 5 and the inlet of the air duct 63. The second material leveling component 9 is used to make the material entering the inlet evenly distributed.

[0074] In this embodiment, when conveying discrete Chinese herbal medicines, the second uniform feeding component 9 evenly feeds the Chinese herbal medicines into the feed inlet of the air duct 63, making the Chinese herbal medicines more evenly distributed in the air duct 63. The structure of the second uniform feeding component 9 is the same as that of the first uniform feeding component 8.

[0075] This application improves the uniformity of materials entering the air duct 63 by using the second uniform material component 9, thereby improving the air separation accuracy and effect of the air separator 6.

[0076] In one embodiment, such as Figure 1 As shown, the herbal medicine purification device also includes an electrical control box 10, which is connected to the splitting component 1, the first dust suction component 2, the first conveying component 3, the second dust suction component 4, the second conveying component 5 and the air separator 6 respectively, to control the opening and closing of each component.

[0077] In this embodiment, the operator can start the entire herbal medicine purification device with one button through the electrical control box 10, and can also control the operation and stop of each component separately as needed.

[0078] This application enables centralized control of all components, facilitating operation and improving work efficiency. It also allows for flexible adjustment of the operating status of each component based on actual production conditions, ensuring stable operation of the equipment.

[0079] In summary, this application is used as follows:

[0080] The operator turns on the entire herbal medicine purification device through the electrical control box 10, and the disassembled components 1, 2, 3, 4, 5 and 6 begin to work.

[0081] Bundles of Prunella vulgaris are placed on the conveyor belt 12 of the splitting component 1. Before splitting, the first dust suction component 2 on the splitting component 1 is activated to remove the first impurities with a small specific gravity, such as dust, carried by the bundles of Prunella vulgaris before splitting.

[0082] Conveyor belt 12 transports bundles of Prunella vulgaris to the discharge end. At this time, the robotic arm 13, corresponding to the discharge end of conveyor belt 12, begins to move, bringing multiple splitting components 14 closer to conveyor belt 31. The splitting rods 141 in the splitting components 14 are tilted in the direction of incoming material and inserted into the bundles of Prunella vulgaris. The reinforcing rods 142 and the splitting rods 141 are arranged in a V-shape, which not only reinforces the splitting rods 141 to prevent them from deforming, but also pushes the split Prunella vulgaris material forward.

[0083] After splitting, the selfheal is broken down into flake-like or block-like material units. The split material units continue to be conveyed by the conveyor belt 31 of the first conveying assembly 3, and the baffles 32 on both sides of the conveyor belt 31 prevent the material from falling off.

[0084] When the material unit moves to the position of the dispersing component 33, the dispersing component 33, which is fixed on the baffle 32, begins to work. The dispersing component 33, with its special structural design, moderately disperses the material unit, reduces the crushing of the Prunella vulgaris raw material, reduces losses, and disperses the material unit into discrete materials.

[0085] During the dispersing process, the second dust collection component 4, which is located on the first conveying component 3, is activated to remove the first impurities generated during the dispersing of the material unit.

[0086] The first conveying assembly 3 conveys the discrete material to the discharge end. Through the feed hopper 7 at the discharge end, the discrete material falls onto the second conveying assembly 5, which is inclined and located on one side of the first conveying assembly 3. The first leveling assembly 8 on one side of the second conveying assembly 5 starts to work, leveling the discrete material to make the material fed into the air classifier 6 through the second conveying assembly 5 evenly distributed.

[0087] Discrete materials are conveyed to the air classifier 6 by the second conveying component 5. Between the discharge end of the second conveying component 5 and the inlet of the air classifier 6, the second uniform material distribution component 9 further uniformizes the material entering the inlet, making the material distribution more uniform.

[0088] The air duct 63 of the air classifier 6 is inclined. The air duct 63 has an inlet near the discharge end of the second conveying component 5 and an impurity outlet 61 far from the discharge end. The fan 64 generates air force.

[0089] After the discrete material enters the air duct 63 through the feed inlet, it utilizes the principle that the specific gravity of Prunella vulgaris is different from that of impurities such as soil and sand. Under the action of wind, the second impurity with a larger specific gravity falls out from the impurity outlet 61. The discrete Prunella vulgaris material after air separation falls out through multiple outlets 62 of the air separator 6, completing the entire purification process.

[0090] After a batch of Prunella vulgaris has been purified, the operator shuts down the splitting assembly 1, the first dust collection assembly 2, the first conveying assembly 3, the second dust collection assembly 4, the second conveying assembly 5, and the air separator 6 via the electrical control box 10, and the device stops operating.

[0091] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
