Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, and more specifically, to a device for testing and grinding traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to drugs collected, processed, and prepared under the guidance of traditional Chinese medical theories, with explanations of their mechanisms of action and guidance for clinical application. It primarily originates from natural medicines and their processed products, including plant-based, animal-based, and mineral-based drugs, as well as some chemical and biological products. Grinding is a crucial step in the testing of TCM materials. Grinding breaks down the medicinal materials into fine powders, facilitating subsequent extraction, separation, detection, and analysis. After grinding, the characteristics of the particle size need to be tested to ensure it meets the requirements for subsequent use.

[0003] Currently, the grinding of Chinese medicinal herbs is usually done using specialized grinding devices. Existing grinding devices include a grinding trough and a grinding wheel. The grinding trough has a semi-circular cross-section. The Chinese medicinal herbs to be ground are placed in the annular grinding trough, and the grinding wheel rolls inside the annular groove. The grinding wheel can grind and crush the Chinese medicinal herbs by its weight. However, during the grinding process, the grinding wheel will squeeze the Chinese medicinal herbs against the side walls of the grinding trough. The Chinese medicinal herbs adhere to the side walls and cannot fall to the bottom of the grinding trough, which means that the grinding wheel cannot grind the Chinese medicinal herbs thoroughly. Summary of the Invention

[0004] To address the problem in the prior art that current grinding devices cannot allow medicinal herbs adhering to the sidewalls to fall to the bottom of the grinding tank, resulting in insufficient grinding, this invention proposes a medicinal herb detection and grinding device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for testing Chinese medicinal materials, comprising a grinding cylinder, a grinding seat fixedly connected inside the grinding cylinder, the grinding seat including an annular grinding groove, a first motor fixedly connected to the bottom of the grinding cylinder, a rotating column fixedly connected to the output shaft of the first motor, a connecting column fixedly connected to the rotating column, and a grinding wheel rolling inside the grinding groove at one end of the connecting column, further comprising:

The two first guide sections are respectively close to the two side walls of the grinding tank, and the two second guide sections are both close to the middle of the grinding tank.

[0008] Furthermore, the scraping assembly includes an arc-shaped rod fixed to an L-shaped rod, one end of which is fixed to a semi-circular arc plate, and a semi-circular arc scraper is fixed to the semi-circular arc plate, the semi-circular arc scraper contacting the outer wall of the grinding wheel.

[0009] Furthermore, the mounting plate is provided with a merging assembly for driving the two guide scrapers to merge and converge. The merging assembly includes a rotating shaft rotatably connected to one end of the two mounting plates. A rotating block is fixed to the outer wall of the rotating shaft. A square plate is fixed to the bottom of the rotating block. The square plate is fixed to the guide scraper. A rotating block is fixed to the top of the rotating shaft. The two rotating blocks form a 45-degree angle with the corresponding rotating block.

[0010] Furthermore, the grinding cylinder is equipped with a drive assembly for driving the merging component. The drive assembly includes a second motor fixed to the top of the grinding cylinder, with a threaded rod fixed to the output shaft of the second motor. A fixed ring plate is fixed to the inner wall of the grinding cylinder, and the bottom end of the threaded rod is rotatably connected to the fixed ring plate. A lifting ring plate is threaded to the outer wall of the threaded rod. Multiple guide rods penetrating the fixed ring plate are fixed to the lifting ring plate. A circular limiting block is fixed to the bottom end of each guide rod. The circular limiting block has a trapezoidal cross-section and is provided with a first T-shaped circular groove and a second... The diameter of the second T-shaped ring slide groove is smaller than that of the first T-shaped ring slide groove. A connecting slide groove is provided on the ring limiting block to connect the first T-shaped ring slide groove and the second T-shaped ring slide groove. A limiting wheel is provided in the first T-shaped ring slide groove. A folded rod is rotatably connected to the limiting wheel through a rotating column. The folded rod is slidably connected to the arc rod through a limiting plate. Two connecting plates are fixed to the folded rod. A vertical rod is fixed to the connecting plate. Limiting holes are provided on both rotating blocks. The two vertical rods are respectively inserted into the corresponding limiting holes.

[0011] Furthermore, multiple connecting rods are fixedly connected to the lifting ring plate, and multiple discharge ports are opened on the grinding seat and grinding cylinder. One end of the connecting rod extends into the discharge port and is fixedly connected to a circular plate. A sealing block is fixedly connected to the circular plate, and a circular ring seat is provided on the outer wall of the sealing block. The circular ring seat is fixedly connected to the inner wall of the discharge port.

[0012] Furthermore, a rotating sleeve is rotatably connected to the outer wall of the connecting column, the grinding wheel is fixedly connected to the outer wall of the rotating sleeve, a helical gear is fixedly connected to the outer wall of the rotating sleeve, and an annular helical rack that meshes with the helical gear is fixedly connected to the top of the grinding seat.

[0013] Furthermore, a crossbar is fixed to the outer wall of the connecting column, a feeding hopper is fixed to one end of the crossbar, a discharge pipe is fixed to the bottom end of the feeding hopper, a rotating shaft is rotatably connected to the discharge pipe, a sealing plate is fixed to one end of the rotating shaft, the sealing plate has multiple holes, the sealing plate is used to seal the discharge pipe, a rotating block is fixed to the other end of the rotating shaft, and a rubber block that abuts against the rotating block is fixed to the outer wall of the discharge pipe.

[0014] The technical effects and advantages of the Chinese herbal medicine testing and grinding device of the present invention are as follows:

[0015] (1) By setting up a guide component, during the grinding process of the first motor driving the grinding wheel in the grinding tank, the grinding wheel will squeeze the Chinese medicinal materials onto the two side walls of the grinding tank, and the Chinese medicinal materials will adhere to the side walls of the grinding tank and are difficult to fall off, resulting in insufficient grinding of this part of the Chinese medicinal materials. During the rotation of the first motor driving the rotating column and the grinding wheel, the rotating column drives the guide scraper to move in the grinding tank through the L-shaped rod. The two guide scrapers can guide the Chinese medicinal materials on the side wall to the middle of the grinding tank through the first guide section and the second guide section, so as to carry out subsequent grinding operations, thereby achieving the purpose of scraping off the Chinese medicinal materials attached to the side wall of the grinding tank and guiding them to the middle of the grinding tank.

[0016] (2) By setting up a merging component and a driving component, after grinding, the Chinese medicinal materials in the grinding tank need to be discharged. Start the second motor to drive the threaded rod to rotate. The threaded rod drives the lifting ring plate to move downward. The lifting ring plate drives the circular ring limiting block to move downward through the guide rod. The downward movement of the circular ring guide block can allow the limiting wheel to enter the second T-shaped circular ring slide through the connecting slide. That is, the circular ring limiting block can push the limiting wheel and the folding rod to move towards the center of the grinding seat. The folding rod can drive the rotating block and the rotating shaft to rotate through the vertical rod and the limiting port. The rotating shaft drives the guide scraper to rotate through the rotating block and the square plate, so that the guide scraper folds. One end of the two guide scrapers contacts each other. During the rotation of the guide scraper with the rotating column, the guide scraper can scrape the Chinese medicinal materials to the discharge port to achieve the purpose of automatically discharging the Chinese medicinal materials.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figures 1-8A traditional Chinese medicine grinding and testing device includes a grinding cylinder 1, a grinding seat 2 fixedly connected inside the grinding cylinder 1, the grinding seat 2 including an annular grinding groove 3, a first motor 4 fixedly connected to the bottom of the grinding cylinder 1, a rotating column 5 fixedly connected to the output shaft of the first motor 4, a connecting column 6 fixedly connected to the rotating column 5, and a grinding wheel 7 rolling inside the grinding groove 3 at one end of the connecting column 6. The device also includes:

[0029] L-shaped rod 8 is fixed to rotating column 5. One end of L-shaped rod 8 is provided with a guide component for guiding Chinese medicinal materials on the side wall of grinding tank 3 to the bottom of grinding tank 3. L-shaped rod 8 is also provided with a scraping component for scraping off Chinese medicinal materials attached to grinding wheel 7.

[0030] In use, the Chinese medicinal materials to be ground are evenly placed in the grinding trough 3. The first motor 4 is started, which drives the rotating column 5 to rotate. The rotating column 5 drives the connecting column 6 to rotate, and the connecting column 6 drives the grinding wheel 7 to roll in the grinding trough 3. The grinding wheel 7, together with the grinding trough 3, crushes and grinds the Chinese medicinal materials. At the same time, the rotating column 5 drives the guiding component through the L-shaped rod 8. The guiding component is located behind the grinding wheel 7 and rotates around the rotating column 5. The guiding component can scrape off the Chinese medicinal materials attached to the side wall of the grinding trough 3 and guide them to the middle of the grinding trough 3 for subsequent grinding. This solves the problem that the current grinding device cannot make the Chinese medicinal materials attached to the side wall fall to the bottom of the grinding trough 3, resulting in insufficient grinding. By setting up the scraping component, the Chinese medicinal materials attached to the grinding wheel 7 can be scraped off during the grinding process. After grinding is completed, the Chinese medicinal materials are taken out of the grinding trough 3. After taking them out, the particle characteristics of the Chinese medicinal materials need to be tested so that they can be further processed or used.

[0031] Reference Figure 2 , Figure 3 and Figure 4The guiding assembly includes a horizontal plate 9 fixed to one end of an L-shaped rod 8. Two mounting plates 10 are fixed to the horizontal plate 9, and two guide scrapers 11 are fixed to the mounting plates 10. The guide scrapers 11 are in contact with the bottom of the grinding tank 3 and are elastic. Each guide scraper 11 includes a first guide section 1101 and a second guide section 1102. The two first guide sections 1101 are respectively close to the two side walls of the grinding tank 3, and the two second guide sections 1102 are both close to the middle of the grinding tank 3. The two guide scrapers 11 are combined to form a Y shape. The connection between the first guide section 1101 and the second guide section 1102 is located in the middle section of the guide scraper 11. The middle section is the transition section between the first guide section 1101 and the second guide section 1102, so as to guide the Chinese medicinal materials to the grinding tank. In the middle of the grinding groove 3, the distance between the two first guide sections 1101 is greater than the distance between the two second guide sections 1102. During the movement of the rotating column 5 and the grinding wheel 7 driven by the first motor 4, the rotating column 5 drives the horizontal plate 9 and the mounting plate 10 to rotate around the rotating column 5 through the L-shaped rod 8. The mounting plate 10 drives the two guide scrapers 11 to move in the grinding groove 3. Since the two first guide sections 1101 are close to the two side walls of the grinding groove 3 respectively, and the two second guide sections 1102 are close to the middle of the grinding groove 3, during the movement of the guide scrapers 11, the Chinese medicinal materials on the side walls of the grinding groove 3 can be scraped off through the two first guide sections 1101 and guided to the middle of the two second guide sections 1102, that is, the Chinese medicinal materials are guided to the middle of the grinding groove 3 so that the grinding wheel 7 can crush and grind the Chinese medicinal materials.

[0032] Reference Figure 3 and Figure 4 The scraping assembly includes an arc-shaped rod 12 fixed to an L-shaped rod 8. A semi-circular arc plate 13 is fixed to one end of the arc-shaped rod 12. A semi-circular arc scraper 14 is fixed to the semi-circular arc plate 13. The semi-circular arc scraper 14 is in contact with the outer wall of the grinding wheel 7. During the movement of the first motor 4 driving the rotating column 5 and the grinding wheel 7, the L-shaped rod 8 drives the arc-shaped rod 12 to move, the arc-shaped rod 12 drives the semi-circular arc plate 13 to move, and the semi-circular arc plate 13 drives the semi-circular arc scraper 14 to move. The semi-circular arc scraper 14 moves with the grinding wheel 7. Since the semi-circular arc scraper 14 is always in contact with the outer wall of the grinding wheel 7, the semi-circular arc scraper 14 can scrape off the Chinese medicinal materials attached to the grinding wheel 7.

[0033] Reference Figure 4The mounting plate 10 is provided with a merging assembly for driving two guide scrapers 11 to merge together. The merging assembly includes a rotating shaft 15 rotatably connected to one end of the two mounting plates 10. A rotating block 16 is fixed to the outer wall of the rotating shaft 15. A square plate 17 is fixed to the bottom of the rotating block 16 and is fixed to the guide scraper 11. A rotating block 18 is fixed to the top of the rotating shaft 15. The two rotating blocks 18 form a 45-degree angle with their respective rotating blocks 16. After grinding, the Chinese medicinal materials in the grinding tank 3 need to be scraped out of the grinding tank 3, so that the two rotating blocks 18 rotate 90 degrees simultaneously. One of the rotating blocks 18 drives one of the rotating shafts 15 and the rotating block 16 to rotate together. When the clockwise rotation is 90 degrees, another rotating block 18 drives another rotating shaft 15 and rotating block 16 to rotate 90 degrees counterclockwise. The two rotating blocks 16 simultaneously drive the square plate 17 to rotate around the corresponding rotating shaft 15. The square plate 17 drives the guide scraper 11 to rotate, and the guide scraper 11 folds. One end of the two rotating blocks 16 approaches each other until the two rotating blocks 16 rotate 90 degrees and one end faces each other. At this time, one end of the two guide scrapers 11 contacts each other, forming a closed arc. The guide scraper 11 is always in contact with the bottom of the grinding tank 3. Then, the L-shaped rod 8 drives the guide scraper 11 to move. The guide scraper 11 can scrape the Chinese medicinal materials in the grinding tank 3 and scrape the Chinese medicinal materials to the discharge port to be discharged from the grinding tank 3.

[0034] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6The grinding cylinder 1 is equipped with a drive assembly for driving the merging component. The drive assembly includes a second motor 19 fixedly connected to the top of the grinding cylinder 1. A threaded rod 20 is fixedly connected to the output shaft of the second motor 19. A fixed ring plate 21 is fixedly connected to the inner wall of the grinding cylinder 1. The bottom end of the threaded rod 20 is rotatably connected to the fixed ring plate 21. A lifting ring plate 22 is threadedly connected to the outer wall of the threaded rod 20. A plurality of guide rods 23 penetrating the fixed ring plate 21 are fixedly connected to the lifting ring plate 22. A circular ring limiting block 24 is fixedly connected to the bottom end of the guide rod 23. The cross-section of the circular ring limiting block 24 is trapezoidal. The positioning block 24 has a first T-shaped annular groove 25 and a second T-shaped annular groove 26. The diameter of the second T-shaped annular groove 26 is smaller than the diameter of the first T-shaped annular groove 25. The annular limiting block 24 has a connecting groove 27 for connecting the first T-shaped annular groove 25 and the second T-shaped annular groove 26. A limiting wheel 28 is provided in the first T-shaped annular groove 25. A folded rod 29 is rotatably connected to the limiting wheel 28 via a rotating column. The folded rod 29 is slidably connected to the arc-shaped rod 12 via a limiting plate. Two connecting plates 30 are fixedly connected to the folded rod 29. A vertical rod 31 is fixedly connected to the connecting plate 30. Limiting ports 32 are provided on both rotating blocks 18, and the two vertical rods 31 are respectively inserted into the corresponding limiting ports 32. During normal grinding by the first motor 4 driving the grinding wheel 7, the limiting wheel 28 moves within the first T-shaped annular groove 25. When the grinding is complete and the medicinal materials need to be discharged, the limiting wheel 28 moves to the position aligned with the connecting groove 27, and the second motor 19 is started. The second motor 19 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the lifting ring plate 22 to move downwards. The lifting ring plate 22 drives the annular limiting block 24 to move downwards via the guide rod 23. The downward movement of the positioning block 24 allows the limiting wheel 28 to enter the connecting groove 27, and the limiting wheel 28 to enter the second T-shaped annular groove 26 through the connecting groove 27. That is, the annular limiting block 24 can push the limiting wheel 28 and the folded rod 29 to move towards the rotating column 5. The folded rod 29 drives the two vertical rods 31 to move through the connecting plate 30. The two vertical rods 31 can drive the two rotating blocks 18 to rotate 90 degrees through the limiting port 32, thereby merging the two guide scrapers 11 to scrape the Chinese medicinal materials. After merging, the guide scrapers 11 can be driven to move through the first motor 4. At this time, the limiting wheel 28 moves in the second T-shaped annular groove 26.

[0035] Reference Figure 2 , Figure 5 and Figure 7Multiple connecting rods 33 are fixedly connected to the lifting ring plate 22. Multiple discharge ports are provided on the grinding seat 2 and grinding cylinder 1. A detection device (not shown in the figure) is fixedly connected to the bottom of the grinding cylinder 1 below each discharge port. The detection device can detect the Chinese medicinal materials discharged from the discharge ports, determining their particle characteristics. One end of each connecting rod 33 extends into the discharge port and is fixedly connected to a circular plate 34. A sealing block 35 is fixedly connected to the circular plate 34. A circular ring seat 36 is provided on the outer wall of the sealing block 35. The annular seat 36 is fixed to the inner wall of the outlet. After grinding is completed, the second motor 19 is started to drive the lifting ring plate 22 to move downward, thereby driving the two guide scrapers 11 to merge. At the same time, the lifting ring plate 22 drives the connecting rod 33 to move downward. The connecting rod 33 drives the sealing block 35 to move downward through the circular plate 34, so that the sealing block 35 leaves the annular seat 36. The Chinese herbal medicine powder can be discharged from the middle of the annular seat 36 into the grinding tank 3. By resetting the sealing block 35 upward, the middle of the annular seat 36 can be sealed, and the grinding operation can be carried out normally.

[0036] Reference Figure 2 and Figure 3 The outer wall of the connecting column 6 is rotatably connected to a rotating sleeve 37. The grinding wheel 7 is fixedly connected to the outer wall of the rotating sleeve 37. A helical gear 38 is fixedly connected to the outer wall of the rotating sleeve 37. The top of the grinding seat 2 is fixedly connected to an annular helical rack 39 that meshes with the helical gear 38. During the rotation of the rotating column 5 driven by the first motor 4, the rotating column 5 drives the grinding wheel 7 to move in the grinding groove 3 through the rotating sleeve 37. At the same time, the rotating sleeve 37 drives the helical gear 38 to walk on the annular helical rack 39, so that the grinding wheel 7 rolls in the grinding groove 3, preventing the grinding wheel 7 from slipping in the grinding groove 3 and causing insufficient grinding.

[0037] Reference Figure 2 and Figure 8A crossbar 40 is fixed to the outer wall of the connecting column 6. A feeding hopper 41 is fixed to one end of the crossbar 40. A discharge pipe 42 is fixed to the bottom end of the feeding hopper 41. A rotating shaft 43 is rotatably connected to the discharge pipe 42. A sealing plate 44 is fixed to one end of the rotating shaft 43. The sealing plate 44 has multiple holes and is used to seal the discharge pipe 42. A rotating block 45 is fixed to the other end of the rotating shaft 43. A rubber block 46 that abuts against the rotating block 45 is fixed to the outer wall of the discharge pipe 42. The Chinese medicinal materials to be ground are placed into the feeding hopper 41. The rotating block 45 is rotated. The rotating block 45 drives the sealing plate 44 to rotate through the rotating shaft 43, so that the sealing plate 46... 4. Rotate 90 degrees. There is friction between the rotating block 45 and the rubber block 46 to prevent the sealing plate 44 from rotating randomly. Start the first motor 4 to drive the rotating column 5 to rotate. The rotating column 5 drives the feeding hopper 41 to rotate through the crossbar 40, so that the Chinese medicinal materials in the feeding hopper 41 are discharged through the discharge pipe 42. The Chinese medicinal materials fall evenly into the grinding tank 3. After the Chinese medicinal materials are added, rotate the rotating block 45 to close the sealing plate 44. When it is necessary to add lubricant or other materials during the grinding process, put the lubricant or other materials into the feeding hopper 41. The lubricant or other materials can fall through the holes of the sealing plate 44. The feeding hopper 41, which rotates around the rotating column 5, can evenly put the lubricant or other materials into the Chinese medicinal materials in the grinding tank 3.

[0038] Working principle: When in use, the Chinese medicinal materials to be ground are evenly placed in the grinding tank 3. The first motor 4 is started, and the first motor 4 drives the rotating column 5 to rotate. The rotating column 5 drives the connecting column 6 to rotate. The connecting column 6 can drive the grinding wheel 7 to roll in the grinding tank 3. The grinding wheel 7 works with the grinding tank 3 to crush and grind the Chinese medicinal materials. At the same time, the rotating column 5 drives the guide component through the L-shaped rod 8. The guide component is located behind the grinding wheel 7 and rotates around the rotating column 5. The guide component can scrape off the Chinese medicinal materials attached to the side wall of the grinding tank 3 and guide them to the middle of the grinding tank 3 for subsequent grinding. This solves the problem that the current grinding device cannot make the Chinese medicinal materials attached to the side wall fall to the bottom of the grinding tank 3, resulting in insufficient grinding. By setting up the scraping component, the Chinese medicinal materials attached to the grinding wheel 7 can be scraped off during the grinding process of the grinding wheel 7.

[0039] During the movement of the first motor 4 driving the rotating column 5 and the grinding wheel 7, the rotating column 5 drives the horizontal plate 9 and the mounting plate 10 to rotate around the rotating column 5 via the L-shaped rod 8. The mounting plate 10 drives the two guide scrapers 11 to move in the grinding groove 3. Since the two first guide sections 1101 are close to the two side walls of the grinding groove 3 respectively, and the two second guide sections 1102 are close to the middle of the grinding groove 3, during the movement of the guide scrapers 11, the Chinese medicinal materials on the side walls of the grinding groove 3 can be scraped off through the two first guide sections 1101 and guided to the middle of the two second guide sections 1102, that is, the Chinese medicinal materials are guided to the middle of the grinding groove 3 so that the grinding wheel 7 can crush and grind the Chinese medicinal materials subsequently.

[0040] During the movement of the first motor 4 driving the rotating column 5 and the grinding wheel 7, the L-shaped rod 8 drives the arc rod 12 to move, the arc rod 12 drives the semi-circular arc plate 13 to move, the semi-circular arc plate 13 drives the semi-circular arc scraper 14 to move, and the semi-circular arc scraper 14 moves with the grinding wheel 7. Since the semi-circular arc scraper 14 is always in contact with the outer wall of the grinding wheel 7, the semi-circular arc scraper 14 can scrape off the Chinese medicinal materials attached to the grinding wheel 7.

[0041] After grinding is completed, the Chinese medicinal materials in the grinding tank 3 need to be scraped out of the grinding tank 3. The two rotating blocks 18 rotate 90 degrees at the same time. One rotating block 18 drives one of the rotating shafts 15 and rotating blocks 16 to rotate 90 degrees clockwise. The other rotating block 18 drives the other rotating shaft 15 and rotating blocks 16 to rotate 90 degrees counterclockwise. The two rotating blocks 16 simultaneously drive the square plate 17 to rotate around the corresponding rotating shaft 15. The square plate 17 drives the guide scraper 11 to rotate. The guide scraper 11 folds and one end of the two rotating blocks 16 approaches each other until the two rotating blocks 16 rotate 90 degrees and one end of them faces each other. At this time, one end of the two guide scrapers 11 contacts each other and forms a closed arc. The guide scraper 11 is always in contact with the bottom of the grinding tank 3. Then, the L-shaped rod 8 drives the guide scraper 11 to move. The guide scraper 11 can scrape the Chinese medicinal materials in the grinding tank 3 and scrape the Chinese medicinal materials to the discharge port to be discharged from the grinding tank 3.

[0042] During normal grinding by the first motor 4 driving the grinding wheel 7, the limiting wheel 28 moves within the first T-shaped annular groove 25. When the grinding is complete and the medicinal materials need to be discharged, the limiting wheel 28 moves to the position aligned with the connecting groove 27, and the second motor 19 is started. The second motor 19 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the lifting ring plate 22 to move downward. The lifting ring plate 22 drives the annular limiting block 24 to move downward through the guide rod 23. The downward movement of the annular limiting block 24 allows the limiting wheel 28 to enter the connecting groove 27, thus limiting the movement. Wheel 28 enters the second T-shaped annular groove 26 through connecting groove 27, that is, the annular limiting block 24 can push the limiting wheel 28 and the folded rod 29 to move towards the rotating column 5. The folded rod 29 drives the two vertical rods 31 to move through the connecting plate 30. The two vertical rods 31 can drive the two rotating blocks 18 to rotate 90 degrees through the limiting port 32, thereby merging the two guide scrapers 11 to scrape the Chinese medicinal materials. After merging, the guide scrapers 11 can be driven to move through the first motor 4. At this time, the limiting wheel 28 moves in the second T-shaped annular groove 26.

[0043] After grinding is completed, starting the second motor 19 can drive the lifting ring plate 22 to move downward, thereby driving the two guide scrapers 11 to merge. At the same time, the lifting ring plate 22 drives the connecting rod 33 to move downward. The connecting rod 33 drives the sealing block 35 to move downward through the circular plate 34, so that the sealing block 35 leaves the circular seat 36. The Chinese herbal medicine powder can be discharged from the middle of the circular seat 36 into the grinding tank 3. By resetting the sealing block 35 upward, the middle of the circular seat 36 can be sealed, and the grinding operation can be carried out normally.

[0044] During the rotation of the first motor 4 driving the rotating column 5, the rotating column 5 drives the grinding wheel 7 to move in the grinding groove 3 through the rotating sleeve 37. At the same time, the rotating sleeve 37 drives the helical gear 38 to walk on the annular helical rack 39, so that the grinding wheel 7 rolls in the grinding groove 3, preventing the grinding wheel 7 from slipping in the grinding groove 3 and causing insufficient grinding.

[0045] The Chinese medicinal materials to be ground are placed into the feeding hopper 41. The rotating block 45 is rotated, and the rotating block 45 drives the sealing plate 44 to rotate through the rotating shaft 43, causing the sealing plate 44 to rotate 90 degrees. There is friction between the rotating block 45 and the rubber block 46 to prevent the sealing plate 44 from rotating arbitrarily. The first motor 4 is started to drive the rotating column 5 to rotate. The rotating column 5 drives the feeding hopper 41 to rotate through the crossbar 40, so that the Chinese medicinal materials in the feeding hopper 41 are discharged through the discharge pipe 42. The Chinese medicinal materials fall evenly into the grinding tank 3. After the Chinese medicinal materials are added, the rotating block 45 is rotated to close the sealing plate 44. When it is necessary to add lubricant or other materials during the grinding process, the lubricant or other materials are put into the feeding hopper 41. The lubricant or other materials can fall through the holes of the sealing plate 44. The feeding hopper 41, which rotates around the rotating column 5, can evenly add the lubricant or other materials to the Chinese medicinal materials in the grinding tank 3.
