Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, and in particular to a grinding and crushing device for traditional Chinese medicine pharmacies. Background Technology

[0002] Grinding and crushing traditional Chinese medicine (TCM) is a process that uses mechanical force to pulverize large pieces of solid TCM materials to a suitable fineness. The external forces applied to the pulverizing material by the pulverizing machinery mainly fall into the following categories: cutting, squeezing, grinding, impacting, splitting, tearing, and filing. The ease of pulverizing a medicine depends primarily on its structure and properties, and is also closely related to the magnitude of the external force. Currently, most grinding mechanisms used are automated, which are often unsuitable for grinding and crushing small doses of TCM and are inconvenient for pharmacists to dispense medication on demand. Therefore, we propose a TCM pharmacy grinding and crushing device to address the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, where the grinding mechanisms currently in use are mostly automated, which are often unsuitable for grinding and pulverizing small doses of traditional Chinese medicine and are not convenient for pharmacists to prepare medicines at any time. Therefore, this invention proposes a grinding and crushing device for traditional Chinese medicine pharmacies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A grinding and crushing device for traditional Chinese medicine pharmacies includes a grinding tube, a hand ring fixedly fitted on the grinding tube, a retaining ring clamped on the grinding tube, a support plate fixedly installed on the inner side of the retaining ring, and a through hole on the support plate. The crushing device also includes:

[0006] The grinding mechanism is a through-hole that fits into the inner wall of the through-hole. The bottom of the grinding mechanism extends into the grinding tube. The grinding mechanism fits into the inner wall of the grinding tube and is used to pulverize and grind Chinese medicinal materials.

[0007] The screening mechanism is installed at the bottom of the grinding tube and is used to screen the ground Chinese medicinal materials granules.

[0008] In one possible design, the grinding mechanism includes a rotating shaft and a limiting tube fixedly installed at the bottom of a support plate. The limiting tube corresponds to the position of the perforation. The rotating shaft passes through the perforation and the limiting tube respectively, and the rotating shaft contacts the inner wall of the limiting tube. The bottom end of the rotating shaft extends into the grinding tube and a grinding roller is fixedly installed thereon. The grinding roller cooperates with the inner wall of the grinding tube for grinding and crushing Chinese medicinal materials. An adapter groove is opened at the bottom of the grinding roller. A connecting arm is fixedly installed at the top of the rotating shaft, and a hand crank is rotatably connected to one side of the top of the connecting arm.

[0009] In one possible design, the rotating shaft has multiple annular slots at equal intervals, a support assembly is installed on the top of the support plate, and an arc-shaped locking strip is connected to the support assembly. The arc-shaped locking strip is movably and slidably engaged with the multiple annular slots.

[0010] In one possible design, the support assembly includes a fixed plate fixedly mounted on one side of the top of the support plate, a pull rod slidably connected through the fixed plate, one end of the pull rod being fixedly connected to an arc-shaped retaining strip, and a tension spring being sleeved on the pull rod, with both ends of the tension spring being fixedly connected to the pull rod and one side of the fixed plate, respectively.

[0011] In one possible design, mounting plates are fixedly installed on the top of both sides of the grinding tube, ball head clamps are fixedly installed on the top of the mounting plates, insert plates are fixedly installed on both sides of the clamping ring, insert plates have insertion holes, rubber sleeves are fixedly installed in the insertion holes, and ball head clamps pass through the corresponding rubber sleeves and are movably clamped with the rubber sleeves.

[0012] In one possible design, the screening mechanism includes a first threaded ring fixedly mounted on a grinding tube, a second threaded ring threadedly connected to the first threaded ring, a mating ring fixedly mounted on the inner side of the second threaded ring, the mating ring being sleeved on the bottom end of the grinding tube, a screen plate fixedly mounted on the inner side of the mating ring, a mating shaft fixedly mounted at the top center of the screen plate, the top end of the mating shaft extending into the adapter groove, and the mating shaft contacting the inner side wall of the adapter groove.

[0013] In this application, during actual use, when first clamping the retaining ring to the top of the grinding tube, the grinding roller can be placed inside the grinding tube. Simultaneously, the connecting shaft can be inserted into the adapter groove to support and limit the grinding roller, preventing positional displacement when the grinding roller is squeezed by the medicinal materials during rotation. Two ball-head clamping rods can then pass through their corresponding rubber sleeves. As the ball-head clamping rods pass through the corresponding rubber sleeves, the inner wall of the rubber sleeves deforms, allowing the rubber sleeves to wrap around the ball-head clamping rods, creating a stable clamping effect. Next, the longitudinal movement of the rotating shaft adjusts the height of the grinding roller, thereby adjusting the distance between the bottom of the grinding roller and the inclined surface of the grinding tube, thus enabling the grinding of the medicinal materials to a specified degree. After adjusting the height of the grinding roller to the desired size, the pull rod can be released. The tension spring, under stress, pulls the pull rod closer to the rotating shaft, causing the arc-shaped locking strip to move into the corresponding annular groove. This allows for automatic positioning of the rotating shaft. Next, the medicinal herbs are placed into the grinding tube. The rotating shaft can then be rotated by turning the hand crank, which in turn rotates the grinding roller. With the support of the grinding tube, the medicinal herbs are ground and crushed. The crushed herbs fall onto the screen plate, where the particles are screened. After grinding, the second threaded ring can be twisted to disengage from the first threaded ring, allowing the herbs on the screen plate to be cleaned.

[0014] Beneficial effects: In this utility model, the Chinese medicine grinding and crushing device can grind and crush Chinese medicines by means of a grinding mechanism. After the Chinese medicinal materials are put into the grinding tube, the rotating shaft can be driven to rotate by turning the hand crank. At this time, the grinding roller can be driven to rotate. In this way, with the support of the grinding tube, the Chinese medicinal materials can be ground and crushed.

[0015] In this utility model, the traditional Chinese medicine grinding and crushing device, through a screening mechanism, allows the traditional Chinese medicine to be ground into granules and fall onto the screen plate when the screen plate is set at the bottom of the grinding tube. At this time, the screen plate can be used to screen the granules of traditional Chinese medicine. After the traditional Chinese medicine is ground, the second threaded ring can be twisted to disengage it from the first threaded ring, thereby cleaning the traditional Chinese medicine that has fallen onto the screen plate. Furthermore, the docking shaft, after being inserted into the adapter groove, can support and limit the grinding roller, so that the grinding roller will not shift its position when squeezed by the traditional Chinese medicine during rotation.

[0016] This invention features a grinding tube that allows pharmacists to easily operate it by hand, enabling them to grind and crush small doses of Chinese medicinal herbs, thus providing pharmacists with excellent ease of use when preparing Chinese medicinal herbs in their daily practice.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-4 A crushing device is disclosed, which mainly includes a grinding tube 1, with a hand ring 2 fixedly fitted on the outside of the grinding tube 1 for easy hand rotation. Above the grinding tube 1, a retaining ring 3 is clamped, and a support plate 8 is fixedly installed on the inner side of the retaining ring 3. The support plate 8 has a through hole for the grinding mechanism to pass through.

[0024] The grinding mechanism mainly consists of a rotating shaft 10. At the bottom of the support plate 8, a limiting tube 9 corresponding to the perforation position is fixedly installed. The rotating shaft 10 passes through the perforation and the limiting tube 9 sequentially, and is in close contact with the inner wall of the limiting tube 9. The bottom of the rotating shaft 10 extends into the grinding tube 1, and a grinding roller 14 is fixedly installed thereon. The grinding roller 14 fits tightly with the inner wall of the grinding tube 1, and is used to pulverize and grind the added Chinese medicinal materials. An adapter groove 15 is provided at the bottom of the grinding roller 14. At the top of the rotating shaft 10, a connecting arm 12 is fixedly installed, and a hand crank 13 is rotatably connected to one side of the top of the connecting arm 12. When grinding Chinese medicinal materials is required, simply put the materials into the grinding tube 1, and then rotate the hand crank 13 to drive the rotating shaft 10 to rotate, thereby driving the grinding roller 14 to rotate inside the grinding tube 1, grinding and crushing the Chinese medicinal materials.

[0025] To adjust the distance between the grinding roller 14 and the inner wall of the grinding tube 1 to accommodate the grinding needs of different Chinese medicinal materials, multiple annular slots 11 are evenly spaced on the rotating shaft 10. A support assembly is installed on the top of the support plate 8, and an arc-shaped locking strip 23 is connected to the support assembly. The arc-shaped locking strip 23 can slide and engage with the multiple annular slots 11. By moving the rotating shaft 10 longitudinally, the height of the grinding roller 14 can be adjusted, thereby changing the distance between the bottom of the grinding roller 14 and the inclined portion of the grinding tube 1. After adjustment, the height of the rotating shaft 10 can be limited by engaging the arc-shaped locking strip 23 with the corresponding annular slot 11, without affecting its normal rotation.

[0026] The support assembly mainly consists of a fixed plate 21 fixedly installed on one side of the top of the support plate 8. A pull rod 22 is slidably connected through the fixed plate 21, and one end of the pull rod 22 is fixedly connected to an arc-shaped retaining strip 23. A tension spring 24 is sleeved on the pull rod 22, and both ends of the tension spring 24 are fixedly connected to the pull rod 22 and one side of the fixed plate 21, respectively. When the grinding roller 14 is moved to the specified height, the pull rod 22 is released. The tension of the tension spring 24 will cause the pull rod 22 to move the arc-shaped retaining strip 23 closer to the rotating shaft 10 until the arc-shaped retaining strip 23 is engaged in the corresponding annular groove 11, thereby achieving automatic positioning of the rotating shaft 10.

[0027] To secure the grinding tube 1 and the retaining ring 3, mounting plates 6 are fixedly installed on the top of both sides of the grinding tube 1, and ball-head retaining rods 7 are fixedly installed on the top of the mounting plates 6. Insert plates 4 are fixedly installed on both sides of the retaining ring 3, with insertion holes on the insert plates, and rubber sleeves 5 are fixedly installed inside the insertion holes. When the retaining ring 3 is engaged with the top of the grinding tube 1, the two ball-head retaining rods 7 pass through the corresponding rubber sleeves 5. Because the rubber sleeves 5 are elastic, when the ball-head retaining rods 7 pass through the rubber sleeves 5, the inner wall of the rubber sleeves 5 deforms and wraps around the ball-head retaining rods 7, forming a stable engagement effect.

[0028] This application can be used in the field of traditional Chinese medicine processing technology, or in other fields applicable to this application.

[0029] Example 2: Reference Figure 2 An improvement upon Embodiment 1: A grinding and crushing device for traditional Chinese medicine pharmacies, applied to the field of traditional Chinese medicine processing technology, comprises a screening mechanism mainly consisting of a first threaded ring 16 fixedly installed at the bottom of a grinding tube 1, with a second threaded ring 17 threadedly connected to the first threaded ring 16. A connecting ring 18 is fixedly installed on the inner side of the second threaded ring 17, and the connecting ring 18 is sleeved on the bottom end of the grinding tube 1. A screen plate 19 is fixedly installed on the inner side of the connecting ring 18, and a connecting shaft 20 is fixedly installed at the top center of the screen plate 19. The top end of the connecting shaft 20 extends into the adapter groove 15 at the bottom of the grinding roller 14 and is in close contact with the inner side wall of the adapter groove 15. When the traditional Chinese medicine is ground into granules, it falls onto the screen plate 19 for screening. After grinding is completed, the second threaded ring 17 is twisted to disengage it from the first threaded ring 16, thus easily cleaning the traditional Chinese medicine granules that have fallen onto the screen plate 19. Meanwhile, after the docking shaft 20 is inserted into the adapter groove 15, it can support and limit the grinding roller 14 to prevent it from shifting position due to the squeezing of Chinese medicinal materials during rotation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
