Description

Technical Field

[0001] This utility model relates to the field of rotary screening machine technology, specifically to a rotary screening machine for traditional Chinese medicine. Background Technology

[0002] In the processing of traditional Chinese medicine, screening is a crucial preliminary step. The screening effect directly affects the quality and efficiency of subsequent processing, extraction, and preparation. The efficacy and value of traditional Chinese medicine are often closely related to its size and shape. Different parts or different growth stages of the same medicinal material will have different contents of active ingredients. By screening and processing medicinal materials of uniform size, it is possible to ensure uniform heating during processing and consistent dissolution rate of active ingredients during extraction, thereby ensuring the quality stability of the final product.

[0003] Traditional Chinese medicine (TCM) herbal screening mainly relies on manual screening. Operators need to use simple tools such as sieves to separate herbs of different sizes by shaking and sorting. This method is not only extremely labor-intensive, but also very inefficient for large-scale TCM processing, making it difficult to meet the needs of industrial production. Moreover, the accuracy of manual screening depends entirely on the operator's experience. Different people have different screening standards, which can easily lead to inconsistent specifications of the screened herbs, requiring corresponding solutions. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rotary screening machine for Chinese herbal medicines, which can effectively solve the problems of low screening efficiency and inaccurate grading of herbal medicines in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a rotary screening machine for traditional Chinese medicine, including a machine body;

[0007] A rotary screening mechanism includes a rotary screening component, a vibration component, and a partitioning component. The rotary screening component includes a motor fixedly connected to the upper surface of the machine body via a bracket. The output end of the motor is fixedly connected to a rotating shaft, which is rotatably connected to the inner top surface of the machine body via a bearing. A support cylinder is fixedly connected to the bottom end of the rotating shaft, and a connecting column is slidably connected inside the support cylinder. A screen cylinder is fixedly connected to the bottom end of the connecting column. A feed groove is provided on the side wall of the screen cylinder. Two limiting grooves are provided on the side wall of the support cylinder, and limiting blocks are slidably connected in both limiting grooves. Both limiting blocks are fixedly connected to the side wall of the connecting column. A spring is fixedly connected between the top end of the connecting column and the inner top surface of the support cylinder.

[0008] According to the above-mentioned rotary screening machine for Chinese herbal medicine, the vibration component includes a fixed plate fixedly connected to the inner wall of the machine body. The upper surface of the fixed plate is provided with a through groove. An annular plate is fixedly connected to the circumference of the sieve cylinder. Multiple hemispheres of the first type are fixedly connected at equal intervals on the upper surface of the fixed plate. Two hemispheres of the second type are fixedly connected to the bottom surface of the annular plate.

[0009] According to the above-mentioned rotary screening machine for Chinese herbal medicines, the partitioning component includes a first filtration zone, a second filtration zone, and a third filtration zone located on the bottom surface of the sieve cylinder. Multiple annular guide plates are fixedly connected to the bottom surface of the sieve cylinder, and a collection box is fixedly connected to the inner bottom surface of the machine body. A first annular partition and a second annular partition are fixedly connected inside the collection box.

[0010] According to the above-mentioned rotary screening machine for Chinese herbal medicines, the filter pore sizes of the first, second, and third filtration zones gradually increase.

[0011] According to the above-mentioned rotary screening machine for traditional Chinese medicine, the sieve cylinder has a through groove, and multiple hemispheres are equidistantly arranged around the axis of the sieve cylinder.

[0012] According to the above-mentioned rotary screening machine for Chinese herbal medicines, multiple annular guide plates are respectively matched with the first filtration zone, the second filtration zone, and the third filtration zone. The first annular partition, the second annular partition, the collection box, the sieve cylinder, and the multiple annular guide plates are all concentrically arranged.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] 1. This utility model provides rotational power to the sieve cylinder through the set rotating screening component, so that the Chinese herbal medicines in the sieve cylinder are evenly distributed and fully contact the sieve surface under the action of rotational force. At the same time, under the action of spring, the connecting column can drive the sieve cylinder to move up and down slightly, enhance the relative movement between the Chinese herbal medicines and the sieve surface, improve the initial screening effect, and the cooperation between the limiting groove and the limiting block ensures that the connecting column rotates synchronously with the support cylinder, ensuring the stability of the screening process.

[0015] 2. The present invention, through the vibration component, can generate regular vibration of the sieve cylinder by the alternating contact between the second hemisphere and multiple first hemispheres while the sieve cylinder rotates. This vibration can effectively prevent the accumulation of Chinese herbal medicines on the sieve surface and blockage of the sieve holes, while further improving the screening efficiency and thoroughness.

[0016] 3. This utility model, through its partitioned components, can grade and screen Chinese herbal medicines using three filtration zones with different pore sizes. Simultaneously, with the cooperation of the annular guide plate, the first annular partition, and the second annular partition, Chinese herbal medicines of different specifications are accurately guided to the corresponding areas in the collection box for collection. This achieves precise grading of Chinese herbal medicines, meets the diverse needs of different processing scenarios for the specifications of Chinese herbal medicines, and improves the practicality of the equipment.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4 A rotary screening machine for traditional Chinese medicine, comprising a body 1;

[0026] The rotary screening mechanism includes a rotary screening component 2, a vibration component 3, and a partitioning component 4. The rotary screening component 2 includes a motor 21 fixedly connected to the upper surface of the machine body 1 via a bracket. The output end of the motor 21 is fixedly connected to a rotating shaft 22. The rotating shaft 22 is rotatably connected to the inner top surface of the machine body 1 via a bearing. The bottom end of the rotating shaft 22 is fixedly connected to a support cylinder 23. A connecting column 24 is slidably connected inside the support cylinder 23. The bottom end of the connecting column 24 is fixedly connected to a screen cylinder 25. A feed groove 26 is provided on the side wall of the screen cylinder 25. Two limiting grooves 27 are provided on the side wall of the support cylinder 23. Limiting blocks 28 are slidably connected in both limiting grooves 27. Both limiting blocks 28 are fixedly connected to the side wall of the connecting column 24. A spring 29 is fixedly connected between the top end of the connecting column 24 and the inner top surface of the support cylinder 23.

[0027] The vibration assembly 3 includes a fixing plate 31 fixedly connected to the inner wall of the machine body 1. A through groove is opened on the upper surface of the fixing plate 31. An annular plate 32 is fixedly connected to the circumference of the screen cylinder 25. Multiple first hemispheres 33 are fixedly connected at equal intervals on the upper surface of the fixing plate 31. Two second hemispheres 34 are fixedly connected to the bottom surface of the annular plate 32. The screen cylinder 25 passes through the through groove. The multiple first hemispheres 33 are all equidistantly arranged around the axis of the screen cylinder 25.

[0028] The partitioning component 4 includes a first filtration zone 41, a second filtration zone 42, and a third filtration zone 43 located on the bottom surface of the sieve cylinder 25. Multiple annular guide plates 44 are fixedly connected to the bottom surface of the sieve cylinder 25. A collection box 45 is fixedly connected to the inner bottom surface of the machine body 1. A first annular partition 46 and a second annular partition 47 are fixedly connected inside the collection box 45. The filter holes of the first filtration zone 41, the second filtration zone 42, and the third filtration zone 43 are gradually increasing in size. By using filter holes of different sizes, the herbs can be graded and screened. The multiple annular guide plates 44 cooperate with the first filtration zone 41, the second filtration zone 42, and the third filtration zone 43 respectively. The first annular partition 46, the second annular partition 47, the collection box 45, the sieve cylinder 25, and the multiple annular guide plates 44 are all concentrically arranged.

[0029] The working principle of this utility model is as follows: When in use, the herbs to be screened are added into the sieve cylinder 25 through the feeding trough 26. Then, the motor 21 is started. When the motor 21 is powered on, its output shaft drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the support cylinder 23 to rotate synchronously. Under the locking action of the limiting block 28 and the limiting groove 27, the connecting column 24 rotates together with the support cylinder 23, thereby making the sieve cylinder 25 rotate synchronously. The herbs put into the sieve cylinder 25 diffuse to the surroundings under the action of centrifugal force and fully contact the filtration area at the bottom of the sieve cylinder 25. At the same time, under the action of the subsequent vibration component 3, the connecting column 24 will slide up and down in the support cylinder 23, and the spring 29 will extend and retract accordingly, so that the sieve cylinder 25 will move up and down while rotating, which enhances the friction and collision between the herbs and the sieve surface, thereby improving the screening effect.

[0030] When the sieve cylinder 25 rotates under the drive of the rotating screening component 2, the annular plate 32 rotates synchronously with the sieve cylinder 25. The two second hemispheres 34 on its bottom surface will alternately contact the multiple first hemispheres 33 on the fixed plate 31. When the spherical surface of the second hemisphere 34 collides with the spherical surface of the first hemisphere 33, an upward thrust will be generated, pushing the annular plate 32 and the sieve cylinder 25 to move upward. The connecting column 24 will move upward in the support cylinder 23 and compress the spring 29. When the second hemisphere 34 rotates away from the first hemisphere 33, the elastic force of the spring 29 will push the connecting column 24 downward, causing the sieve cylinder 25 and the annular plate 32 to return to their original position. This cycle repeats, causing the sieve cylinder 25 to vibrate up and down while rotating. This vibration can make the Chinese herbal medicines in the sieve cylinder 25 jump continuously, effectively preventing the medicinal materials from clogging the sieve holes, ensuring the smooth progress of the screening process, and further improving the screening efficiency and thoroughness.

[0031] Under the combined action of rotation and vibration of the sieve cylinder 25, the Chinese herbal medicines inside the sieve cylinder 25 continuously come into contact with the bottom filtration zone. Since the filter pore sizes of the first filtration zone 41, the second filtration zone 42, and the third filtration zone 43 gradually increase, the Chinese herbal medicines with smaller diameters will fall through the filter pores of the first filtration zone 41 and, blocked by the innermost annular guide plate 44, fall into the collection chamber inside the first annular partition 46 in the collection box 45. The Chinese herbal medicines with medium diameters will fall through the filter pores of the second filtration zone 42 and, guided by the middle annular guide plate 44, fall into the collection chamber between the first annular partition 46 and the second annular partition 47. The Chinese herbal medicines with larger diameters will fall through the filter pores of the third filtration zone 43 and fall into the collection chamber outside the second annular partition 47. The Chinese herbal medicines with even larger diameters will remain inside the sieve cylinder 25, thus completing the grading and screening.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
