Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine extraction, and particularly relates to a traditional Chinese medicine extraction device. Background Art

[0002] The development process of the traditional Chinese medicine extraction device industry can be traced back to the early 20th century. At that time, traditional Chinese medicine extraction mainly relied on manual operation, with low extraction efficiency and low purity of the extract. With the development of technology and the acceleration of the industrialization process, traditional Chinese medicine extraction equipment has gradually achieved automation and intelligence. In the 1980s of the 20th century, a variety of new traditional Chinese medicine extraction equipment emerged, such as ultrasonic extraction equipment, multi-functional extraction tanks, dynamic extraction equipment, etc. These equipment adopted advanced extraction technologies, such as ultrasonic enhanced extraction, dynamic extraction, etc., improving the efficiency and purity of traditional Chinese medicine extraction. Entering the 21st century, the traditional Chinese medicine extraction equipment industry has been further developed, and the structure and function of the equipment have become more perfect.

[0003] When some existing traditional Chinese medicine extraction devices perform traditional Chinese medicine extraction, they only crush the traditional Chinese medicine raw materials, and do not screen the crushed traditional Chinese medicine. This may affect the extraction quality during the extraction process.

[0004] In summary, the problem that the existing traditional Chinese medicine extraction devices may affect the extraction quality during the extraction process has become a difficult problem that urgently needs to be solved in this field. Therefore, it is necessary to propose a traditional Chinese medicine extraction device. Summary of the Invention

[0005] To solve the above problems, the present invention provides a traditional Chinese medicine extraction device. Through the design of the screening component, the extraction device can screen the particle size of traditional Chinese medicine raw materials, ensuring that the traditional Chinese medicine raw materials entering the extraction frame have a uniform particle size, thereby improving the extraction efficiency and the quality of the extract.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A traditional Chinese medicine extraction device includes a drive box. A side wall of the drive box is fixedly connected with an extraction frame. The top of the extraction frame is fixedly connected with a protection frame. A feed inlet is opened on the protection frame. The device also includes a controller. An inner side wall of the drive box is fixedly connected with a horizontal partition. The horizontal partition divides the interior of the drive box into a movement cavity and a placement cavity from top to bottom in sequence. An inner side wall of the movement cavity is fixedly connected with a fixed rod. One end of the fixed rod far from the inner side wall of the movement cavity is fixedly connected with a driving member. The controller is used to control the rotation of the output shaft of the driving member.

[0007] The extraction frame is provided with a screening component for screening the particle size of traditional Chinese medicine raw materials, a shaking component for shaking the screening component, and a stirring component for stirring and extracting traditional Chinese medicine raw materials. The shaking component is located below the screening component, and the stirring component is located below the shaking component.

[0008] On the output shafts at both ends of the driving member, there are respectively a first transmission assembly for driving the screening assembly to operate and a second transmission assembly for driving the stirring assembly to operate. The second transmission assembly is located below the first transmission assembly, and the first transmission assembly is located on one side of the screening assembly.

[0009] The first transmission assembly includes a first worm gear coaxially and fixedly connected to the output shaft at one end of the driving member. On the inner side wall of the movement cavity, there are symmetrically fixedly connected fixing frames. Between adjacent fixing frames, there is a worm rotatably fitted. The first worm gear meshes with the worm. On one side of the driving box, there is a sliding block slidably fitted horizontally. At the bottom of the sliding block, there is a second worm gear rotatably fitted. On the side wall of the movement cavity, there is a first through hole, and the second worm gear meshes with the worm through the first through hole.

[0010] The screening assembly includes a screening frame hinged to the sliding block, and a filter screen is detachably connected to the screening frame.

[0011] At the lower part of the extraction frame, there is a discharge port, and a rubber plug is detachably connected to the discharge port.

[0012] The technical principle of the above solution is as follows: The staff crushes the traditional Chinese medicine raw materials and puts them into the extraction frame through the feed port, so that they enter the screening frame, and adds the extraction liquid into the extraction frame.

[0013] The staff controls the rotation of the output shaft of the driving member through the controller, so that it drives the first worm gear to rotate. The first worm gear drives the worm to rotate. The worm drives the second worm gear to rotate. The second worm gear drives the sliding block to slide horizontally on the side wall of the driving box, so that it drives the screening frame to move horizontally and screen the traditional Chinese medicine raw materials. During this process, the screening frame will vibrate under the action of the vibration assembly, further enhancing the screening effect of the traditional Chinese medicine raw materials.

[0014] During the rotation of the output shaft of the driving member far from the first worm gear, it drives the second transmission assembly to operate, and the second transmission assembly drives the stirring assembly to operate, stirring the traditional Chinese medicine raw materials and the extraction liquid.

[0015] After the extraction is completed, the staff removes the rubber plug and discharges the extraction liquid in the extraction frame to complete the extraction of the traditional Chinese medicine.

[0016] The above solution has the following beneficial effects: 1. In the present invention, through the design of the screening assembly, the extraction device can screen the particle size of the traditional Chinese medicine raw materials, thereby ensuring that the traditional Chinese medicine raw materials entering the extraction frame have uniform particle size, and thus improving the extraction efficiency and the quality of the extract.

[0017] 2. In the present invention, the setting of the jitter component helps to prevent the traditional Chinese medicine raw materials from clogging the filter screen during the screening process, thereby improving the screening efficiency. By rotating the output shaft of the driving member, the first transmission component is driven to operate. Then, through the meshing transmission between the worm and the second worm gear, the sliding block and the screening frame generate jitter, effectively promoting the uniform distribution of the traditional Chinese medicine raw materials on the filter screen, thus improving the screening effect.

[0018] 3. In the present invention, the rotational force of the output shaft of the driving member is transmitted to the stirring component through the second transmission component, achieving sufficient stirring of the traditional Chinese medicine raw materials, and improving the extraction efficiency and the uniformity of the extract.

[0019] Furthermore, the stirring component includes a stirring rod rotatably fitted to the inner bottom wall of the extraction frame, and a plurality of stirring blades are fixedly connected to the side wall of the stirring rod in the circumferential direction.

[0020] Beneficial effects: The cooperation between the stirring rod and the stirring blades can achieve sufficient stirring of the traditional Chinese medicine raw materials, ensuring the uniform distribution of the traditional Chinese medicine raw materials in the extraction liquid. Through its stirring effect, the active ingredients of the traditional Chinese medicine raw materials can be dissolved into the extraction liquid more quickly, thereby improving the extraction efficiency.

[0021] Furthermore, the second transmission component includes a first gear coaxially and fixedly connected to the output shaft of the driving member at the end far from the first worm gear. The first gear meshes with a chain, and the chain meshes with a second gear, and the second gear is coaxially and fixedly connected to the stirring rod.

[0022] Beneficial effects: The chain drive has the characteristics of stable transmission, low noise, and strong load-bearing capacity. By connecting the first gear and the second gear through the chain, the rotational force of the first gear can be effectively transmitted to the second gear.

[0023] Furthermore, the jitter component includes a jitter block fixedly connected to the inner side wall of the extraction frame. The jitter block is located in the movement path of the screening frame and is made of an elastic material.

[0024] Beneficial effects: Due to its elastic characteristics, the jitter block can cause slight jitter of the filter screen during its movement, which can break the clogging or accumulation of the traditional Chinese medicine raw materials that may form on the filter screen, enabling the traditional Chinese medicine raw materials to pass through the filter screen more smoothly, thereby improving the filtering efficiency.

[0025] Furthermore, a guiding cylinder is fixedly connected at the feed inlet.

[0026] Beneficial effects: The presence of the guiding cylinder helps to reduce the clogging of the traditional Chinese medicine raw materials at the feed inlet. At the same time, under the action of gravity, the traditional Chinese medicine raw materials can more easily slide along the guiding cylinder, avoiding the problem of unsmooth feeding caused by the accumulation of the traditional Chinese medicine raw materials.

[0027] Furthermore, a dust-proof cover plate is detachably connected to the top of the guiding cylinder.

[0028] Beneficial effects: The design of the dust-proof cover plate helps to maintain the cleanliness of the extraction process and ensure the quality of extraction.

[0029] Furthermore, an observation plate is fixedly connected to one side wall of the extraction frame, and the observation plate is made of a transparent material.

[0030] Beneficial effects: The transparent observation plate enables the staff to directly observe the extraction situation inside the extraction frame, ensuring that the staff can monitor the specific situation during the extraction process in real time, so as to take necessary intervention measures in a timely manner.

[0031] Furthermore, anti-slip layers are fixedly connected to the bottom of both the drive box and the extraction frame.

[0032] Beneficial effects: The design of the anti-slip layer significantly improves the friction between the drive box and the extraction frame and the placement surface, thereby enhancing the stability of the extraction device during operation.

[0033] Furthermore, an opening and closing door is hinged at the position of the placement cavity on the side wall of the drive box.

[0034] Beneficial effects: The design of the opening and closing door enables the staff to easily place the items to be used in the placement cavity.

[0035] Furthermore, the guide cylinder is in an inverted conical shape.

[0036] Beneficial effects: The design of the inverted conical guide cylinder can reduce the resistance of the traditional Chinese medicine raw materials during the flow process, enabling them to pass through the guide cylinder more smoothly and enter the extraction frame.

[0037] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. Description of the Drawings

Detailed implementation manners

[0044] The following is a further detailed description through specific implementation manners: Embodiment 1: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 : A traditional Chinese medicine extraction device includes a drive box 1 and a controller. An extraction frame 2 is integrally formed on the side wall of the drive box 1. Anti-slip layers are fixedly adhered to the bottoms of both the drive box 1 and the extraction frame 2. A protective frame 3 is welded to the top of the extraction frame 2. A feed inlet is opened on the protective frame 3. A transverse partition 4 is welded to the inner side wall of the drive box 1. The transverse partition 4 divides the interior of the drive box 1 into a movement cavity and a placement cavity from top to bottom in sequence. An opening and closing door 5 is hinged at the position of the placement cavity on the side wall of the drive box 1. A fixing rod 6 is welded to the inner side wall of the movement cavity. One end of the fixing rod 6 away from the inner side wall of the movement cavity is bolted and fixedly connected to a driving member. The controller is used to control the rotation of the output shaft of the driving member. In this embodiment, the driving member is selected as a double-headed motor.

[0045] A screening assembly for screening the particle size of traditional Chinese medicine raw materials, a shaking assembly for shaking the screening assembly, and a stirring assembly for stirring and extracting traditional Chinese medicine raw materials are provided in the extraction frame 2. The shaking assembly is located below the screening assembly, and the stirring assembly is located below the shaking assembly.

[0046] The screening assembly includes a screening frame 7 hinged to a sliding block 12, and a filter screen 8 is detachably clamped on the screening frame 7.

[0047] The shaking assembly includes a shaking block 9 fixedly adhered to the inner side wall of the extraction frame 2. The shaking block 9 is located in the movement path of the screening frame 7, and the shaking block 9 is made of an elastic material. In this embodiment, the material of the shaking block 9 is selected as rubber.

[0048] First transmission assemblies for driving the operation of the screening assembly and second transmission assemblies for driving the operation of the stirring assembly are respectively provided on the output shafts at both ends of the double-headed motor. The second transmission assembly is located below the first transmission assembly, and the first transmission assembly is located on one side of the screening assembly.

[0049] The first transmission assembly includes a first worm gear 10 coaxially and fixedly clamped to the output shaft at one end of the double-headed motor. Fixed frames are symmetrically welded to the inner side wall of the movement cavity. A worm 11 is rotatably fitted between adjacent fixed frames. The first worm gear 10 meshes with the worm 11. A sliding block 12 is horizontally slidably fitted to one side of the drive box 1. A second worm gear 13 is rotatably fitted to the bottom of the sliding block 12. A first through hole is formed in the side wall of the movement cavity. The second worm gear 13 meshes with the worm 11 through the first through hole.

[0050] The stirring assembly includes a stirring rod 14 rotatably fitted to the inner bottom wall of the extraction frame 2. A plurality of stirring blades 15 are integrally formed on the side wall of the stirring rod 14 in the circumferential direction.

[0051] The second transmission assembly includes a first gear 16 coaxially and fixedly clamped to the output shaft at the end of the double-headed motor away from the first worm gear 10. The first gear 16 meshes with a chain 17. The chain 17 meshes with a second gear 18. The second gear 18 is coaxially and fixedly clamped to the stirring rod 14.

[0052] A discharge port is formed in the lower part of the extraction frame 2. A rubber plug 19 is detachably clamped at the discharge port.

[0053] The specific implementation process is as follows: The staff puts the crushed traditional Chinese medicine raw materials into the screening frame 7 inside the extraction frame 2 through the feed port, and adds the extraction liquid into the extraction frame 2. Then, the staff controls the rotation of the output shaft of the double-headed motor through the controller, so that it drives the first worm gear 10 to rotate. The first worm gear 10 drives the worm 11 to rotate. The worm 11 drives the second worm gear 13 to rotate. At this time, since the second worm gear 13 is rotatably fitted with the sliding block 12, and the sliding block 12 is horizontally slidably fitted to one side of the drive box 1, when the second worm gear 13 rotates, it will drive the sliding block 12 to move horizontally along the groove direction of the worm 11, so that the sliding block 12 drives the screening frame 7 to move horizontally, and the traditional Chinese medicine raw materials are screened.

[0054] Since the shaking block 9 is located in the movement path of the screening frame 7, and since the sliding block 12 is hinged to the screening frame 7, the screening frame 7 will contact the shaking block 9 when moving horizontally, causing the screening frame 7 to shake, further improving the screening effect of the traditional Chinese medicine raw materials.

[0055] After the screening of the traditional Chinese medicine raw materials is completed, they are lowered into the extraction frame 2 and mixed with the extraction liquid. At this time, the output shaft of the double-headed motor away from the first worm gear 10 drives the first gear 16 to rotate during rotation. The first gear 16 drives the chain 17 to rotate. The chain 17 drives the second gear 18 to rotate. The second gear 18 drives the stirring rod 14 to rotate. The stirring rod 14 drives the stirring blades 15 to rotate together with it, fully stirring and mixing the traditional Chinese medicine raw materials with the extraction liquid, and extracting the traditional Chinese medicine raw materials.

[0056] After completing the extraction operation of traditional Chinese medicine raw materials, the staff removed the rubber stopper 19, and then released the extract after the traditional Chinese medicine extraction was completed, thus completing the traditional Chinese medicine extraction operation.

[0057] In the present invention, by screening the particle size of traditional Chinese medicine raw materials, it is ensured that the traditional Chinese medicine raw materials entering the extraction frame 2 have a uniform particle size, thereby improving the efficiency of traditional Chinese medicine extraction and the quality of the extract.

[0058] Example 2: As shown in the attached Figure 1 and Figure 5 figures, the difference from Example 1 is that a conical guide cylinder 20 is welded at the feed inlet, and a dust-proof cover plate is detachably clamped at the top of the guide cylinder 20.

[0059] The specific implementation process is as follows: When the traditional Chinese medicine raw materials enter the extraction frame 2 through the guide cylinder 20, due to the conical design of the guide cylinder 20, it will reduce the resistance of the traditional Chinese medicine raw materials during the flow process, enabling them to more smoothly enter the extraction frame 2 through the guide cylinder 20. The dust-proof cover plate can block external impurities, thereby reducing the pollution suffered by the traditional Chinese medicine raw materials during the extraction process.

[0060] Example 3: As shown in the attached Figure 1 and Figure 2 figures, the difference from Example 2 is that an observation plate 21 is embedded and installed on one side wall of the extraction frame 2, and the observation plate 21 is made of a transparent material.

[0061] The specific implementation process is as follows: During the extraction process, the staff can observe the extraction situation of the traditional Chinese medicine raw materials in real time through the observation plate 21. Thus, when the extraction degree of the traditional Chinese medicine raw materials is insufficient, the staff can take necessary intervention measures in a timely manner, such as increasing the rotation speed of the stirring rod 14 to drive the rotation speed of the stirring blade 15 to increase together, thereby increasing the stirring rate of the traditional Chinese medicine raw materials and the extract.

[0062] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
