Description

Technical Field

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

[0002] The chemical components contained in traditional Chinese medicine are very complex, including both multiple active ingredients, inactive ingredients, and toxic ingredients. Extracting its active ingredients and further separating and purifying them to obtain active monomers is an important content in the field of traditional Chinese medicine research. Traditional Chinese medicine extraction is to use some technologies to extract its active ingredients to the greatest extent, improve the internal quality and clinical treatment effect of traditional Chinese medicine preparations, and maximize the efficacy of traditional Chinese medicine. Traditional Chinese medicine extracts are new traditional Chinese medicine products integrating modern pharmaceutical new technologies. They are raw material products for the production of traditional Chinese patent medicines, which are extracted and purified from clean medicinal materials or processed products through methods such as leaching, clarification, filtration, and evaporation.

[0003] For example, the utility model with the publication number CN214910616U discloses a steaming device for traditional Chinese medicine processing, including a frame. The top of the frame is fixedly connected with a steaming box. The upper surface of the frame is fixedly connected with a connecting box. A communicating pipe is inserted into the connecting box, and the communicating pipe is communicated with the inside of the connecting box. The lower surface of the connecting box is inserted with a first rotating shaft. The outer surface of the first rotating shaft close to the inside of the connecting box is fixedly connected with a fan blade. The lower end of the first rotating shaft is fixedly connected with a first belt pulley. The upper surface of the frame close to the connecting box is rotatably connected with a second rotating shaft. The present invention relates to the technical field of traditional Chinese medicine processing. By driving the rotation of the fan blade with steam, the cam is made to push two moving plates to move reciprocally, which is convenient for controlling the flow direction of steam, making the steam stay in the steaming box for a longer time, and facilitating the full steaming of the traditional Chinese medicine on the placing plate by steam, thereby improving the utilization rate of the medicinal materials.

[0004] The following problems still exist in the above technology when extracting the essence of traditional Chinese medicine:

[0005] 1. In the above technical solution, when extracting traditional Chinese medicine from leaves, since the leaves of traditional Chinese medicine are relatively thin, the leaves of traditional Chinese medicine often stack together. In the above technical solution, only the steam stays in the steaming box for a longer time, resulting in the leaves of traditional Chinese medicine in the middle of the stack not being able to be evaporated, reducing the efficiency of traditional Chinese medicine extraction;

[0006] 2. When extracting traditional Chinese medicine from leaves, the essence oil in the leaves of traditional Chinese medicine adheres to the placing plate, and the essence oil on the placing plate cannot be collected, resulting in waste and a very low extraction ratio.

[0007] In view of the above problems, the present invention document proposes a device and method for extracting traditional Chinese medicine from leaves. Summary of the Invention

[0008] The present invention provides a device and method for extracting traditional Chinese medicine from leaves, which solves the disadvantages in the prior art that the traditional Chinese medicine from leaves piled up in the middle cannot be evaporated, and the essence oil on the placement plate cannot be collected.

[0009] The present invention provides the following technical solutions:

[0010] A device for extracting traditional Chinese medicine from leaves, comprising: an extraction tank and a plurality of metal hollow barrels. A collection barrel is provided on one side of the extraction tank. A rotating shaft is rotatably connected inside the extraction tank. A first partition is fixedly connected inside the extraction tank, and the top end of the rotating shaft rotatably penetrates through the first partition. An air inlet pipe located below the first partition is fixedly connected to one side of the extraction tank;

[0011] A steam extraction structure is arranged on the outer wall of the rotating shaft and is used for extracting the essence of traditional Chinese medicine from leaves;

[0012] A scraping structure is arranged on the outer wall of the rotating shaft and is used for collecting the essence oil adhering to the outer wall of the metal hollow barrel;

[0013] A cleaning structure is arranged inside the collection barrel and is used for collecting the essence oil adhering to the metal hollow barrel.

[0014] In a possible design, the steam extraction structure includes two first rotating shafts and a second rotating shaft rotatably connected to the outer wall of the rotating shaft. The first rotating shaft is located above the second rotating shaft. Synchronous wheels are fixedly sleeved on the outer walls of the first rotating shaft and the second rotating shaft. The two synchronous wheels are connected by a synchronous belt. A torsion spring fixedly connected to the synchronous wheel is sleeved on the outer wall of the first rotating shaft, and the end of the torsion spring away from the synchronous wheel is fixedly connected to the rotating shaft. A breathable pipe is fixedly penetrated through the first partition. An annular pipe communicated with the breathable pipe is fixedly connected to the top of the first partition. A plurality of fan blades are fixedly connected to the outer wall of the rotating shaft, and the fan blades are located below the first partition. The fan blades drive the rotating shaft and a plurality of metal hollow barrels to rotate under the push of steam, so that the metal hollow barrels can receive the evaporation of steam in the extraction tank.

[0015] In a possible design, a load-bearing fixed ring is sleeved on the outer wall of the rotating shaft in a sliding manner. A plurality of first arc-shaped convex plates are fixedly connected to the bottom of the load-bearing fixed ring. A plurality of second arc-shaped convex plates that cooperate with the first arc-shaped convex plates are fixedly connected to the top of the first partition plate. A pull rope is fixedly connected to the top of the load-bearing fixed ring, and the other end of the pull rope is wound around the outer wall of the second rotating shaft. Since the load-bearing fixed ring is relatively heavy, when the rotating shaft drives the load-bearing fixed ring to rotate, the load-bearing fixed ring moves up and down reciprocally under the cooperation of the first arc-shaped convex plates and the second arc-shaped convex plates. When the load-bearing fixed ring moves downward, the load-bearing fixed ring drives the second rotating shaft and the corresponding metal hollow barrel to rotate several circles through the pull rope. At this time, the first rotating shaft and the corresponding metal hollow barrel also rotate. Furthermore, when the rotating shaft drives the metal hollow barrel to rotate, the metal hollow barrel can rotate on its own axis, so that the leafy traditional Chinese medicine accumulated in the metal hollow barrel can be evenly exposed to the steam extraction in the extraction tank, thereby increasing the extraction efficiency.

[0016] In a possible design, the scraping structure includes two first trapezoidal plates and a second trapezoidal plate fixedly connected to the outer wall of the rotating shaft, and the tops of the first trapezoidal plate and the second trapezoidal plate are respectively in contact with the bottom of the corresponding metal hollow barrel. The first trapezoidal plate and the second trapezoidal plate are fixedly connected by an arc-shaped liquid guide rod. A collection groove is provided at the top of the load-bearing fixed ring. A liquid guide round rod located above the collection groove is fixedly connected to the bottom of the second trapezoidal plate. An L-shaped pipe is fixedly penetrated through one side of the load-bearing fixed ring. During the rotation of the metal hollow barrel, the outer walls of a plurality of metal hollow barrels are respectively in contact with the bottoms of the first trapezoidal plate and the second trapezoidal plate. The first trapezoidal plate and the second trapezoidal plate scrape off the essence grease on the outer wall of the metal hollow barrel. The first trapezoidal plate guides the essence grease on the outer wall of the metal hollow barrel to the second trapezoidal plate through the arc-shaped liquid guide rod, and then the second trapezoidal plate guides the essence grease into the collection groove through the liquid guide round rod, so as to further collect the essence grease and avoid waste.

[0017] In a possible design, the cleaning structure includes a second partition fixedly connected inside the collection bucket. A hollow tube rotatably penetrates through the second partition. The top of the collection bucket is fixedly connected with a U-shaped frame rotatably connected to the top end of the hollow tube. The bottom end of the hollow tube is rotatably connected with a hollow shaft fixedly connected to the inner wall of the bottom of the collection bucket. The outer wall of the hollow tube is fixedly sleeved with a disc. A plurality of rotating rods rotatably penetrate through the disc. The top end and the bottom end of the rotating rod are respectively fixedly connected with a first gear and a circular magnet. The inner wall of the top of the U-shaped frame is fixedly connected with a first toothed disc, and the first toothed disc meshes with the first gear. The outer wall of the collection bucket is fixedly sleeved with an annular water pipe. The inner wall of the collection bucket is fixedly connected with a plurality of nozzles communicated with the annular water pipe. When the hollow tube rotates, the hollow tube drives the rotating rod and the metal hollowed-out bucket to rotate through the disc. Since the first gear meshes with the first toothed disc, when the hollow tube drives the metal hollowed-out bucket to rotate, the metal hollowed-out bucket starts to rotate on its own under the action of the rotating rod. The nozzles spray hot water onto the rotating metal hollowed-out bucket to remove the essence grease attached to the metal hollowed-out bucket. Then, the cleaning water is collected, and the essence grease can be extracted from it.

[0018] In a possible design, a support ring is fixedly connected to the inner wall of the extraction tank, and the support ring is flush with the top of the first trapezoidal plate. A sliding ring is slidably connected inside the extraction tank, and the sliding ring is slightly higher than the second trapezoidal plate. U-shaped blocks are fixedly connected to the inner walls of the two opposite sides of the extraction tank. The top of the U-shaped block and the bottom of the sliding ring are elastically connected by a spring. A circular hole is provided on one side of the extraction tank. The bottom of the sliding ring is fixedly connected with two closing plates for closing the circular hole, and the bottom end of the closing plate slidably penetrates through the U-shaped block. When the metal hollowed-out bucket is inserted into the insertion hole, the metal hollowed-out bucket can push the sliding ring downward to make the closing plate close the circular hole. When the metal hollowed-out bucket is taken out of the extraction tank, the sliding ring and the closing plate move upward under the action of the spring elastic force to open the circular hole. Then, a straw can be inserted into the extraction tank and docked with the L-shaped tube to extract and collect the essence grease in the collection tank.

[0019] In a possible design, a plurality of ventilation holes are provided on the top of the extraction tank. An arc-shaped collection cover covering the plurality of ventilation holes is fixedly connected to the top of the extraction tank. The top end of the arc-shaped collection cover is fixedly connected with a guide air pipe. A cooling cylinder is sleeved on the outer wall of the guide air pipe. A liquid inlet pipe is provided on one side of the top of the cooling cylinder. A liquid outlet pipe is provided on one side of the bottom of the cooling cylinder, and the other end of the liquid outlet pipe is communicated with the annular water pipe. A cover is provided at one end of the metal hollowed-out bucket. Two insertion holes are provided on one side of the extraction tank, and the two insertion holes correspond to the first rotating shaft and the second rotating shaft respectively. A sealing plate for closing the insertion hole is provided on one side of the extraction tank.

[0020] In a possible design, a driving motor is fixedly connected to the inner wall of the bottom of the collection bucket, an output shaft of the driving motor is fixedly connected to a second gear, a first toothed ring located below the second partition is fixedly sleeved on the outer wall of the hollow tube, and the first toothed ring meshes with the second gear.

[0021] In a possible design, a connecting pipe located below the first partition is fixedly connected to one side of the extraction tank, the other end of the connecting pipe extends into the collection bucket and is communicated with the hollow shaft, a valve is arranged on the outer wall of the connecting pipe, a plurality of inclined holes are arranged in the hollow tube. When the spray head sprays hot water onto the rotating metal hollow bucket to remove the essence grease attached to the metal hollow bucket, the valve on the connecting pipe is opened, and the steam in the extraction tank enters the hollow tube through the connecting pipe and the hollow shaft. The steam sprays onto the rotating metal hollow bucket through the inclined holes. The essence grease attached to the metal hollow bucket can be softened by the steam, which facilitates the cleaning of the spray head. Then, the cleaning water is collected, and the essence grease can be extracted therefrom.

[0022] The extraction method of the leaf-class traditional Chinese medicine extraction device includes the following steps:

[0023] S1. Put the leaf-class traditional Chinese medicine into a plurality of metal hollow buckets, close the metal hollow buckets through the covers, push the sealing plate to open the insertion holes, insert one end of the plurality of metal hollow buckets into the extraction tank, and the plurality of metal hollow buckets are respectively clamped with the magnets at one ends of the first rotating shaft and the second rotating shaft. During the process of inserting the metal hollow buckets into the extraction tank, the support ring supports the metal hollow bucket located above, and the metal hollow bucket below pushes the sliding ring to move downward. The sliding ring compresses and pushes the closing plate to close the circular hole. Then rotate the rotating shaft, align the other first rotating shaft and the second rotating shaft with the insertion holes, and respectively clamp the plurality of metal hollow buckets with the first rotating shaft and the second rotating shaft in sequence;

[0024] S2. Inject steam into the extraction tank through the air inlet pipe. The steam pushes the fan blade and the rotating shaft to rotate. Then, as the steam moves upward through the air-permeable pipe and the annular pipe, steam extraction is performed on the leaf-class traditional Chinese medicine in the metal hollow buckets. During the rotation of the rotating shaft, the rotating shaft drives the metal hollow buckets to rotate respectively through the first rotating shaft and the second rotating shaft, and the rotating shaft also drives the load-bearing fixing ring and the first arc-shaped convex plate to rotate. The cooperation between the first arc-shaped convex plate and the second arc-shaped convex plate drives the load-bearing fixing ring and the first arc-shaped convex plate to move up and down reciprocally. When the load-bearing fixing ring moves downward, the load-bearing fixing ring drives the second rotating shaft and the corresponding metal hollow bucket to rotate several circles through the pull rope. The second rotating shaft and the metal hollow bucket are connected by a synchronous pulley and a synchronous belt. At this time, the first rotating shaft and the corresponding metal hollow bucket also rotate, and the torsion spring starts to store energy. Therefore, when the rotating shaft drives the metal hollow bucket to rotate, the metal hollow bucket can rotate by itself, so that the leaf-class traditional Chinese medicine accumulated in the metal hollow bucket can be evenly extracted by the steam in the extraction tank, thereby increasing the extraction efficiency;

[0025] S3. When the metal hollow barrel rotates, a part of the evaporated essential oil in the leafy traditional Chinese medicine floats upward with the steam, and a part adheres to the outer wall and the inner wall of the metal hollow barrel. During the rotation of the metal hollow barrel, the outer walls of multiple metal hollow barrels respectively touch the bottoms of the first trapezoidal plate and the second trapezoidal plate. The first trapezoidal plate and the second trapezoidal plate scrape off the essential oil on the outer wall of the metal hollow barrel. The first trapezoidal plate guides the essential oil on the outer wall of the metal hollow barrel to the second trapezoidal plate through the arc-shaped liquid guide rod, and then the second trapezoidal plate guides the essential oil into the collection tank through the liquid guide round rod, so as to further collect the essential oil and avoid waste.

[0026] S4. The steam carrying the essential oil is collected through the air guide pipe. When the steam and the essential oil pass through the cooling cylinder, they are cooled by the cold water in the cooling cylinder, which is convenient for collecting the liquid water and the essential oil in the later stage. The water in the cooling cylinder absorbs the heat of the steam and begins to heat up. The warm water is injected into the annular water pipe through the liquid outlet pipe. The previously used metal hollow barrels are respectively placed into the collection barrel. A magnetic attraction is generated on one end of the metal hollow barrel by the circular magnet. Then the driving motor and the nozzle are started. The driving motor drives the hollow pipe to rotate through the second gear and the first toothed ring. The hollow pipe drives the rotating rod and the metal hollow barrel to rotate through the disc. Since the first gear meshes with the first toothed disc, when the hollow pipe drives the metal hollow barrel to rotate, the metal hollow barrel begins to rotate on its own under the action of the rotating rod. The nozzle sprays hot water onto the rotating metal hollow barrel to remove the essential oil attached to the metal hollow barrel. The valve on the connecting pipe is opened, and the steam in the extraction tank enters the hollow pipe through the connecting pipe and the hollow shaft. The steam sprays onto the rotating metal hollow barrel through the inclined holes. The steam can soften the essential oil attached to the metal hollow barrel, which is convenient for the cleaning of the nozzle. Then the cleaning water is collected, and the essential oil can be extracted from it.

[0027] S5. After the extraction in the extraction tank is completed and the extraction tank is cooled, the insertion hole is opened, and multiple metal hollow barrels are taken out from the first rotating shaft and the second rotating shaft in turn. After the sliding ring loses the extrusion of the metal hollow barrel, it moves upward. The sliding ring drives the closing plate to move upward to release the closing of the circular hole. Then the straw is inserted into the extraction tank through the circular hole and docked with the L-shaped pipe. The collected essential oil can be taken out through the L-shaped pipe.

[0028] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0029] In the present invention, a load-bearing fixed ring is slidably sleeved on the outer wall of the rotating shaft. A plurality of first arc-shaped convex plates are fixedly connected to the bottom of the load-bearing fixed ring. A plurality of second arc-shaped convex plates are fixedly connected to the top of the first partition plate. A pull rope is fixedly connected to the top of the load-bearing fixed ring, and the other end of the pull rope is wound around the outer wall of the second rotating shaft. The rotating shaft drives the load-bearing fixed ring to rotate. The load-bearing fixed ring moves up and down reciprocally under the cooperation of the first arc-shaped convex plates and the second arc-shaped convex plates. When the load-bearing fixed ring moves downward, the load-bearing fixed ring drives the second rotating shaft and the corresponding metal hollow barrel to rotate several circles through the pull rope. At this time, the first rotating shaft also rotates. Furthermore, when the rotating shaft drives the metal hollow barrel to rotate, the metal hollow barrel can rotate self, enabling the leafy traditional Chinese medicine accumulated in the metal hollow barrel to be evenly extracted by steam in the extraction tank and increasing the extraction efficiency;

[0030] In the present invention, two first trapezoidal plates and a second trapezoidal plate are fixedly connected to the outer wall of the rotating shaft, and the tops of the first trapezoidal plate and the second trapezoidal plate respectively touch the bottoms of the corresponding metal hollow barrels. The first trapezoidal plate and the second trapezoidal plate are fixedly connected by an arc-shaped liquid guide rod. A liquid guide round rod is fixedly connected to the bottom of the second trapezoidal plate. During the rotation of the metal hollow barrel, the outer walls of the plurality of metal hollow barrels respectively touch the bottoms of the first trapezoidal plate and the second trapezoidal plate. The first trapezoidal plate and the second trapezoidal plate scrape off the essence grease on the outer walls of the metal hollow barrels. The first trapezoidal plate guides the essence grease on the outer wall of the metal hollow barrel to the second trapezoidal plate through the arc-shaped liquid guide rod. Then the second trapezoidal plate guides the essence grease into the collection tank through the liquid guide round rod, thereby being able to further collect the essence grease and avoid waste;

[0031] In the present invention, a hollow tube rotatably penetrates through the second partition plate. A disc is fixedly sleeved on the outer wall of the hollow tube. A plurality of rotating rods rotatably penetrate through the disc. The top and bottom ends of the rotating rod are respectively fixedly connected with a first gear and a circular magnet. A first toothed disc is fixedly connected to the inner wall of the top of the U-shaped frame. A plurality of nozzles are fixedly connected to the inner wall of the collection barrel. When the hollow tube rotates, the hollow tube drives the rotating rod and the metal hollow barrel to rotate through the disc. Since the first gear meshes with the first toothed disc, the metal hollow barrel starts to rotate self under the action of the rotating rod. The nozzles spray hot water onto the rotating metal hollow barrel to remove the essence grease attached to the metal hollow barrel, and then collect the cleaning water, from which the essence grease can be extracted;

[0032] In the present invention, one side of the extraction tank is fixedly connected with a connecting pipe located below the first partition plate. The other end of the connecting pipe extends into the collection bucket and is communicated with the hollow shaft. A plurality of inclined holes are provided in the hollow pipe. When the spray head sprays hot water onto the rotating metal hollow barrel to remove the essence grease attached to the metal hollow barrel, the valve on the connecting pipe is opened. The steam in the extraction tank enters the hollow pipe through the connecting pipe and the hollow shaft. The steam sprays onto the rotating metal hollow barrel through the inclined holes. The steam can soften the essence grease attached to the metal hollow barrel, facilitating the cleaning of the spray head. Then, the cleaning water is collected, and the essence grease can be extracted therefrom.

[0033] In the present invention, the rotating shaft and the metal hollow barrel are driven to rotate by steam. And the load-bearing fixed ring reciprocates up and down under the cooperation of the first arc-shaped convex plate and the second arc-shaped convex plate, which can drive the rotating metal hollow barrel to rotate self. Thus, the leafy traditional Chinese medicine accumulated in the metal hollow barrel is evenly evaporated by the steam. In addition, when the metal hollow barrel rotates, the first trapezoidal plate and the second trapezoidal plate can scrape and collect the essence grease attached to the outer wall of the metal hollow barrel. And after the cold water in the cooling barrel absorbs the heat of the steam, it can clean and collect the essence grease attached to the metal hollow barrel again, avoiding the waste of essence grease.

[0058] Reference Figure 4 and Figure 5 The steam extraction structure includes two first rotating shafts 10 and a second rotating shaft 11 rotatably connected to the outer wall of the rotating shaft 5, and the first rotating shaft 10 is located above the second rotating shaft 11, the outer walls of the first rotating shaft 10 and the second rotating shaft 11 are fixedly sleeved with a synchronous wheel 13, and the two synchronous wheels 13 are connected by a synchronous belt 14 for transmission, the outer wall of the first rotating shaft 10 is sleeved with a torsion spring 15 fixedly connected to the synchronous wheel 13, and the torsion spring 15 is fixedly connected to the rotating shaft 5 at one end away from the synchronous wheel 13, a ventilation tube 7 is fixedly passed through the first partition 3, and a ring tube 8 connected to the ventilation tube 7 is fixedly connected to the top of the first partition 3, a plurality of fan blades 6 are fixedly connected to the outer wall of the rotating shaft 5 by bolts, and the fan blades 6 are located below the first partition 3, and the fan blades 6 drive the rotating shaft 5 and the plurality of metal hollow barrels 12 to rotate under the push of steam, so that the metal hollow barrels 12 can accept the evaporation of steam in the extraction tank 1.

A pull rope 19 is fixedly connected to the top of the load-bearing fixed ring 16, and the other end of the pull rope 19 is wound around the outer wall of the second rotating shaft 11. Since the load-bearing fixed ring 16 is relatively heavy, when the rotating shaft 5 drives the load-bearing fixed ring 16 to rotate, the load-bearing fixed ring 16 reciprocates up and down under the cooperation of the first arc-shaped convex plate 17 and the second arc-shaped convex plate 18. When the load-bearing fixed ring 16 moves downward, the load-bearing fixed ring 16 drives the second rotating shaft 11 and the corresponding metal hollow barrel 12 to rotate several circles through the pull rope 19. At this time, the first rotating shaft 10 and the corresponding metal hollow barrel 12 also rotate. Therefore, when the rotating shaft 5 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 can rotate by itself, so that the leafy traditional Chinese medicine accumulated in the metal hollow barrel 12 can be evenly extracted by the steam in the extraction tank 1, thereby increasing the extraction efficiency.

The first trapezoidal plate 42 guides the essence grease on the outer wall of the metal hollow barrel 12 to the second trapezoidal plate 43 through the arc-shaped liquid guide rod 44. Then, the second trapezoidal plate 43 guides the essence grease into the collection groove 46 through the liquid guide round rod 45, so as to further collect the essence grease and avoid waste.

[0061] Refer to Figure 9 and Figure 10, the cleaning structure includes a second partition plate 30 fixedly connected inside the collection bucket 2 by bolts. A hollow tube 29 rotatably penetrates through the second partition plate 30. The top of the collection bucket 2 is fixedly connected by bolts with a U-shaped frame 28 rotatably connected to the top end of the hollow tube 29. The bottom end of the hollow tube 29 is rotatably connected with a hollow shaft 40 fixedly connected to the inner wall of the bottom of the collection bucket 2 by bolts. The outer wall of the hollow tube 29 is fixedly sleeved with a disc 31. A plurality of rotating rods 33 rotatably penetrate through the disc 31.

The outer wall of the collection bucket 2 is fixedly sleeved with an annular water pipe 26. The inner wall of the collection bucket 2 is fixedly connected with a plurality of spray heads 27 communicated with the annular water pipe 26. When the hollow tube 29 rotates, the hollow tube 29 drives the rotating rod 33 and the metal hollow barrel 12 to rotate through the disc 31. Since the first gear 34 meshes with the first toothed disc 32, when the hollow tube 29 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 starts to rotate on its own under the action of the rotating rod 33. The spray heads 27 spray hot water onto the rotating metal hollow barrel 12 to remove the essence grease attached to the metal hollow barrel 12. Then, the cleaning water is collected, and the essence grease can be extracted from it.

When the metal hollow barrel 12 is inserted into the insertion hole 9, the metal hollow barrel 12 can push the sliding ring 49 downward to make the closing plate 52 close the circular hole 53. When the metal hollow barrel 12 is taken out of the extraction tank 1, the sliding ring 49 and the closing plate 52 move upward under the action of the elastic force of the spring 51 to open the circular hole 53. Then, a straw can be inserted into the extraction tank 1 and docked with the L-shaped pipe 47 to extract the essence grease in the collection tank 46.

Driven by the steam, the fan blades 6 drive the rotating shaft 5 and a plurality of metal hollow barrels 12 to rotate. Thus, the metal hollow barrels 12 can receive the evaporation of the steam in the extraction tank 1.

[0068] Refer to Figure 6 , a load-bearing fixed ring 16 is slidably sleeved on the outer wall of the rotating shaft 5. A plurality of first arc-shaped convex plates 17 are fixedly connected to the bottom of the load-bearing fixed ring 16 by bolts. A plurality of second arc-shaped convex plates 18 matched with the first arc-shaped convex plates 17 are fixedly connected to the top of the first partition plate 3 by bolts. A pull rope 19 is fixedly connected to the top of the load-bearing fixed ring 16. The other end of the pull rope 19 is wound around the outer wall of the second rotating shaft 11. Since the load-bearing fixed ring 16 is heavy, when the rotating shaft 5 drives the load-bearing fixed ring 16 to rotate, the load-bearing fixed ring 16 reciprocates up and down under the cooperation of the first arc-shaped convex plate 17 and the second arc-shaped convex plate 18. When the load-bearing fixed ring 16 moves downward, the load-bearing fixed ring 16 drives the second rotating shaft 11 and the corresponding metal hollow barrel 12 to rotate several circles through the pull rope 19. At this time, the first rotating shaft 10 and the corresponding metal hollow barrel 12 also rotate. Thus, when the rotating shaft 5 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 can rotate itself. Therefore, the leafy Chinese medicine accumulated in the metal hollow barrel 12 can be evenly extracted by the steam in the extraction tank 1, and the extraction efficiency can be increased.

[0069] Refer to Figure 5, the scraping structure includes two first trapezoidal plates 42 and a second trapezoidal plate 43 fixedly connected to the outer wall of the rotating shaft 5 by bolts, and the tops of the first trapezoidal plate 42 and the second trapezoidal plate 43 respectively touch the bottoms of the corresponding metal hollow barrels 12. The first trapezoidal plate 42 and the second trapezoidal plate 43 are fixedly connected by an arc-shaped liquid guide rod 44. A collection groove 46 is provided at the top of the load-bearing fixed ring 16. A liquid guide round rod 45 located above the collection groove 46 is fixedly connected to the bottom of the second trapezoidal plate 43 by bolts. An L-shaped pipe 47 is fixedly penetrated through one side of the load-bearing fixed ring 16. During the rotation of the metal hollow barrels 12, the outer walls of multiple metal hollow barrels 12 respectively touch the bottoms of the first trapezoidal plate 42 and the second trapezoidal plate 43. The first trapezoidal plate 42 and the second trapezoidal plate 43 scrape off the essence grease on the outer walls of the metal hollow barrels 12. The first trapezoidal plate 42 guides the essence grease on the outer wall of the metal hollow barrel 12 to the second trapezoidal plate 43 through the arc-shaped liquid guide rod 44. Then, the second trapezoidal plate 43 guides the essence grease into the collection groove 46 through the liquid guide round rod 45, so as to further collect the essence grease and avoid waste.

[0070] Refer to Figure 9 and Figure 10 , the cleaning structure includes a second partition plate 30 fixedly connected in the collection barrel 2 by bolts. A hollow tube 29 rotates through the second partition plate 30. The top of the collection barrel 2 is fixedly connected by bolts with a U-shaped frame 28 rotatably connected to the top end of the hollow tube 29. The bottom end of the hollow tube 29 is rotatably connected with a hollow shaft 40 fixedly connected to the inner wall of the bottom of the collection barrel 2 by bolts. A disc 31 is fixedly sleeved on the outer wall of the hollow tube 29. Multiple rotating rods 33 rotate through the disc 31. The top and bottom ends of the rotating rod 33 are respectively fixedly connected by bolts with a first gear 34 and a circular magnet 35. A first toothed disc 32 is fixedly connected to the inner wall of the top of the U-shaped frame 28 by bolts, and the first toothed disc 32 meshes with the first gear 34. An annular water pipe 26 is fixedly sleeved on the outer wall of the collection barrel 2. A plurality of spray heads 27 communicated with the annular water pipe 26 are fixedly connected to the inner wall of the collection barrel 2. When the hollow tube 29 rotates, the hollow tube 29 drives the rotating rod 33 and the metal hollow barrel 12 to rotate through the disc 31. Since the first gear 34 meshes with the first toothed disc 32, when the hollow tube 29 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 starts to rotate on its own under the action of the rotating rod 33. The spray heads 27 spray hot water onto the rotating metal hollow barrel 12 to remove the essence grease attached to the metal hollow barrel 12, and then collect the cleaning water, from which the essence grease can be extracted.

[0071] Refer to Figure 11, a driving motor 37 is fixedly connected to the inner wall of the bottom of the collection bucket 2 through bolts, an output shaft of the driving motor 37 is fixedly connected to a second gear 38, a first toothed ring 36 is fixedly sleeved on the outer wall of the hollow tube 29 and is located below the second partition plate 30, and the first toothed ring 36 meshes with the second gear 38.

[0072] Referring to Figure 3 and Figure 7 , a support ring 48 is fixedly connected to the inner wall of the extraction tank 1 through bolts, and the support ring 48 is flush with the top of the first trapezoidal plate 42. A sliding ring 49 is slidably connected in the extraction tank 1, and the sliding ring 49 is slightly higher than the second trapezoidal plate 43. U-shaped blocks 50 are fixedly connected to the inner walls of the two mutually remote sides of the extraction tank 1 through bolts. A spring 51 is elastically connected between the top of the U-shaped block 50 and the bottom of the sliding ring 49. A circular hole 53 is provided on one side of the extraction tank 1. Two closing plates 52 for closing the circular hole 53 are fixedly connected to the bottom of the sliding ring 49 through bolts, and the bottom end of the closing plate 52 slidably penetrates through the U-shaped block 50. When the metal hollow barrel 12 is inserted into the insertion hole 9, the metal hollow barrel 12 can push the sliding ring 49 downward to make the closing plate 52 close the circular hole 53. When the metal hollow barrel 12 is taken out of the extraction tank 1, the sliding ring 49 and the closing plate 52 move upward under the action of the elastic force of the spring 51 to open the circular hole 53. Then, a straw can be inserted into the extraction tank 1 and docked with the L-shaped pipe 47 to extract the essence oil in the extraction collection tank 46.

[0073] Referring to Figure 12 , Figure 13 and Figure 14 , a connecting pipe 39 is fixedly connected to one side of the extraction tank 1 through bolts and is located below the first partition plate 3. The other end of the connecting pipe 39 extends into the collection bucket 2 and is communicated with the hollow shaft 40. A valve is provided on the outer wall of the connecting pipe 39. A plurality of inclined holes 41 are provided in the hollow tube 29. When the spray head 27 sprays hot water onto the rotating metal hollow barrel 12 to remove the essence oil attached to the metal hollow barrel 12, the valve on the connecting pipe 39 is opened, and the steam in the extraction tank 1 enters the hollow tube 29 through the connecting pipe 39 and the hollow shaft 40. The steam sprays onto the rotating metal hollow barrel 12 through the inclined holes 41. The steam can soften the essence oil attached to the metal hollow barrel 12 to facilitate the cleaning of the spray head 27. Then, the cleaning water is collected, and the essence oil can be extracted therefrom.

[0074] An extraction method of a leaf-based traditional Chinese medicine extraction device includes the following steps:

[0075] S1. Place the leaf-based traditional Chinese medicine into multiple metal hollow barrels 12, close the metal hollow barrels 12 with the cover 55, push the sealing plate 54 to open the insertion hole 9, insert one end of the multiple metal hollow barrels 12 into the extraction tank 1, and the multiple metal hollow barrels 12 are respectively clamped with the magnets at one end of the first rotating shaft 10 and the second rotating shaft 11. During the process of inserting the metal hollow barrels 12 into the extraction tank 1, the support ring 48 supports the metal hollow barrels 12 located above, and the metal hollow barrels 12 below push the sliding ring 49 downward. The sliding ring 49 compresses and pushes the closing plate 52 to close the circular hole 53. Then rotate the rotating shaft 5 to align the first rotating shaft 10 and the second rotating shaft 11 on the other side with the insertion hole 9, and successively clamp the multiple metal hollow barrels 12 with the first rotating shaft 10 and the second rotating shaft 11 respectively;

[0076] S2. Inject steam into the extraction tank 1 through the air inlet pipe 4. The steam pushes the fan blade 6 and the rotating shaft 5 to rotate. Then, as the steam moves upward through the air permeable pipe 7 and the annular pipe 8, steam extraction is carried out on the leaf-based traditional Chinese medicine in the metal hollow barrels 12. During the rotation of the rotating shaft 5, the rotating shaft 5 drives the metal hollow barrels 12 to rotate respectively through the first rotating shaft 10 and the second rotating shaft 11, and the rotating shaft 5 also drives the load-bearing fixed ring 16 and the first arc-shaped convex plate 17 to rotate. The cooperation of the first arc-shaped convex plate 17 and the second arc-shaped convex plate 18 drives the load-bearing fixed ring 16 and the first arc-shaped convex plate 17 to move up and down reciprocally. When the load-bearing fixed ring 16 moves downward, the load-bearing fixed ring 16 drives the second rotating shaft 11 and the corresponding metal hollow barrel 12 to rotate several circles through the pull rope 19. The second rotating shaft 11 and the metal hollow barrel 12 are connected by a synchronous pulley 13 and a synchronous belt 14. At this time, the first rotating shaft 10 and the corresponding metal hollow barrel 12 also rotate, and the torsion spring 15 starts to store energy. Therefore, when the rotating shaft 5 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 can rotate by itself, so that the leaf-based traditional Chinese medicine accumulated in the metal hollow barrel 12 can be evenly extracted by steam in the extraction tank 1, thereby increasing the extraction efficiency;

[0077] S3. When the metal hollow barrel 12 rotates by itself, part of the evaporated essential oil in the leaf-based traditional Chinese medicine floats upward with the steam, and part adheres to the outer wall and inner wall of the metal hollow barrel 12. During the rotation of the metal hollow barrel 12, the outer walls of the multiple metal hollow barrels 12 respectively touch the bottoms of the first trapezoidal plate 42 and the second trapezoidal plate 43. The first trapezoidal plate 42 and the second trapezoidal plate 43 scrape off the essential oil on the outer wall of the metal hollow barrel 12. The first trapezoidal plate 42 guides the essential oil on the outer wall of the metal hollow barrel 12 to the second trapezoidal plate 43 through the arc-shaped liquid guide rod 44. Then, the second trapezoidal plate 43 guides the essential oil into the collection tank 46 through the liquid guide round rod 45, so as to further collect the essential oil and avoid waste;

[0078] S4. The steam carries the essence oil and is collected through the air guide tube 22. When the steam carries the essence oil and is passed through the cooling tube 23, it is cooled by the cold water in the cooling tube 23, so as to facilitate the later collection of liquid water and essence oil. The water in the cooling tube 23 absorbs the heat of the steam and starts to heat up. The warm water is injected into the annular water pipe 26 through the liquid outlet pipe 25. The previously used metal hollow barrels 12 are respectively placed in the collection barrel 2. The circular magnet 35 generates magnetic attraction to one end of the metal hollow barrel 12. Then the driving motor 37 and the nozzle 27 are started. The driving motor 37 drives the hollow tube 29 to rotate through the second gear 38 and the first gear ring 36. The hollow tube 29 drives the rotating rod 33 and the metal hollow barrel 12 through the disc 31. The barrel 12 rotates, and since the first gear 34 is meshed with the first toothed disc 32, when the hollow tube 29 drives the metal hollow barrel 12 to rotate, the metal hollow barrel 12 starts to rotate under the action of the rotating rod 33, and the nozzle 27 sprays hot water to the rotating metal hollow barrel 12 to remove the essential oil attached to the metal hollow barrel 12, and opens the valve on the connecting pipe 39, and the steam in the extraction tank 1 enters the hollow tube 29 through the connecting pipe 39 and the hollow shaft 40, and the steam is sprayed to the rotating metal hollow barrel 12 through the inclined hole 41, and the steam can soften the essential oil attached to the metal hollow barrel 12, which is convenient for cleaning the nozzle 27, and then the cleaning water is collected to extract the essential oil from it;

[0079] S5. When the extraction in the extraction tank 1 is completed and the cooling in the extraction tank 1 is completed, the insertion hole 9 is opened, and the multiple metal hollow barrels 12 are taken out from the first rotating shaft 10 and the second rotating shaft 11 in turn. The sliding ring 49 moves upward after losing the squeezing of the metal hollow barrel 12. The sliding ring 49 drives the closing plate 52 to move upward to release the sealing of the circular hole 53. Then, the straw is inserted into the extraction tank 1 through the circular hole 53 and connected to the L-shaped tube 47. The collected essence oil can be taken out through the L-shaped tube 47.

[0080] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 37 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0081] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

9. An extraction method using the leaf-based traditional Chinese medicine extraction device as described in claim 8, characterized in that, It includes the following steps: S1. Put the leafy traditional Chinese medicine into a plurality of metal hollow barrels (12), close the metal hollow barrels (12) through the cover (55), push the sealing plate (54) to open the insertion hole (9), insert one end of the plurality of metal hollow barrels (12) into the extraction tank (1), and the plurality of metal hollow barrels (12) are respectively clamped with the magnets at one ends of the first rotating shaft (10) and the second rotating shaft (11). During the process of inserting the metal hollow barrels (12) into the extraction tank (1), the support ring (48) supports the metal hollow barrels (12) located above, and the metal hollow barrels (12) below push the sliding ring (49) to move downward. The sliding ring (49) compresses and pushes the closing plate (52) to close the circular hole (53). Then rotate the rotating shaft (5), align the first rotating shaft (10) and the second rotating shaft (11) on the other side with the insertion hole (9), and sequentially clamp the plurality of metal hollow barrels (12) with the first rotating shaft (10) and the second rotating shaft (11) respectively; S2. Inject steam into the extraction tank (1) through the air inlet pipe (4). The steam pushes the fan blade (6) and the rotating shaft (5) to rotate. Then the steam moves upward through the air permeable pipe (7) and the annular pipe (8) to extract the leafy traditional Chinese medicine in the metal hollow barrel (12) by steam. During the rotation of the rotating shaft (5), the rotating shaft (5) drives the metal hollow barrels (12) to rotate respectively through the first rotating shaft (10) and the second rotating shaft (11). And the rotating shaft (5) also drives the load-bearing fixed ring (16) and the first arc-shaped convex plate (17) to rotate. The cooperation of the first arc-shaped convex plate (17) and the second arc-shaped convex plate (18) drives the load-bearing fixed ring (16) and the first arc-shaped convex plate (17) to move up and down reciprocally. When the load-bearing fixed ring (16) moves downward, the load-bearing fixed ring (16) drives the second rotating shaft (11) and the corresponding metal hollow barrel (12) to rotate several circles through the pull rope (19). The second rotating shaft (11) and the metal hollow barrel (12) are connected by a synchronous pulley (13) and a synchronous belt (14). At this time, the first rotating shaft (10) and the corresponding metal hollow barrel (12) also rotate, and the torsion spring (15) starts to store energy. Therefore, when the rotating shaft (5) drives the metal hollow barrel (12) to rotate, the metal hollow barrel (12) can rotate self - rotatably; S3. When the metal hollow barrel (12) rotates, part of the evaporated essential oil in the leaf-type Chinese medicine floats upward with the steam, and part of it adheres to the outer wall and inner wall of the metal hollow barrel (12). During the rotation of the metal hollow barrel (12), the outer walls of multiple metal hollow barrels (12) respectively touch the bottom of the first trapezoidal plate (42) and the second trapezoidal plate (43). The first trapezoidal plate (42) and the second trapezoidal plate (43) scrape off the essential oil on the outer wall of the metal hollow barrel (12). The first trapezoidal plate (42) guides the essential oil on the outer wall of the metal hollow barrel (12) to the second trapezoidal plate (43) through the arc-shaped liquid guiding rod (44), and then the second trapezoidal plate (43) guides the essential oil to the collection tank (46) through the liquid guiding round rod (45); S4. The steam carries the essence oil through the air guide tube (22) and is collected. When the steam carries the essence oil through the cooling tube (23), it is cooled by the cold water in the cooling tube (23) to facilitate the later collection of liquid water and essence oil. The water in the cooling tube (23) absorbs the heat of the steam and begins to heat up. The warm water is injected into the annular water pipe (26) through the liquid outlet pipe (25). The previously used metal hollow barrels (12) are respectively placed in the collection barrel (2). The circular magnet (35) generates magnetic attraction on one end of the metal hollow barrel (12). Then, the driving motor (37) and the nozzle (27) are started. The driving motor (37) drives the hollow tube (29) to rotate through the second gear (38) and the first gear ring (36). The hollow tube (29) drives the rotating rod (33) and the metal hollow barrel (12) to rotate through the disc (31). Since the first gear (34) is meshed with the first gear disc (32), when the hollow tube (29) drives the metal hollow barrel (12) to rotate, the metal hollow barrel (12) starts to rotate under the action of the rotating rod (33). The nozzle (27) sprays hot water toward the rotating metal hollow barrel (12) to remove the essence grease attached to the metal hollow barrel (12). The valve on the connecting pipe (39) is opened, and the steam in the extraction tank (1) enters the hollow tube (29) through the connecting pipe (39) and the hollow shaft (40). The steam is sprayed toward the rotating metal hollow barrel (12) through the inclined hole (41); S5. After the extraction in the extraction tank (1) is completed and the cooling in the extraction tank (1) is completed, the insertion hole (9) is opened and the plurality of metal hollow barrels (12) are sequentially removed from the first rotating shaft (10) and the second rotating shaft (11). The sliding ring (49) moves upward after losing the squeezing of the metal hollow barrels (12). The sliding ring (49) drives the closing plate (52) to move upward to release the sealing of the circular hole (53). Then, the straw is inserted into the extraction tank (1) through the circular hole (53) and docked with the L-shaped tube (47).
