[0002] Ophiopogon japonicus is the tuberous root of the plant Ophiopogon japonicus, belonging to the Liliaceae family. Clinically, it is commonly used in two forms: with and without the core. The earliest mention of removing the core from Ophiopogon japonicus is found in Tao Hongjing's "Mingyi Bielu" (Records of Famous Physicians), which states that Ophiopogon japonicus with the core intact can cause irritability, while removing the core can better nourish the lungs and stomach, and clear the mind.

[0003] Currently, the pharmaceutical industry has a habit of using Ophiopogon japonicus with the core removed, but this is generally done manually. In the process of developing the invention, the inventor discovered that manually removing the core from Ophiopogon japonicus has bottleneck problems such as high difficulty, low efficiency, high cost, and inability to be mass-produced, which limits the choice of using Ophiopogon japonicus with the core removed.

The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0041] This application provides a device for removing the core from Ophiopogon japonicus, including: a hopper 3, a conveying mechanism, a core removal mechanism, an Ophiopogon japonicus collection mechanism, and an Ophiopogon japonicus core collection mechanism.

[0042] like Figures 1 to 6 As shown, hopper 3 is used to provide uncorked Ophiopogon japonicus 50; the conveying mechanism is connected to hopper 3 to receive the uncorked Ophiopogon japonicus 50. The conveying mechanism includes a conveying roller group 6 and a conveying pressure roller group 8. The conveying roller group 6 and the conveying pressure roller group 8 are arranged opposite to each other to define a conveying channel for only a single uncorked Ophiopogon japonicus 50 to pass through. The coring mechanism includes a coring needle 21 and a peeling knife 22. The coring needle 21 has a coring channel 53. The entrance of the coring channel 53 is located at the first end of the coring needle 21. The first end of the coring needle 21 passes through the conveying channel from the outlet of the conveying channel to remove the cork from the uncorked Ophiopogon japonicus 50 and collect the Ophiopogon japonicus core 52 in the coring channel 53. The peeling knife 22 is located on the outer side of the coring needle 21. The cutting edge of the peeling knife 22 faces the discharge direction of the conveying channel to peel off the corked Ophiopogon japonicus 51 fitted on the coring needle 21. The entrance of the Ophiopogon japonicus collection mechanism is located below the peeling knife 22 to collect the peeled corked Ophiopogon japonicus 51. The outlet of the core removal channel 53 is located at the second end of the core removal needle 21, and the second end of the core removal needle 21 extends into the Ophiopogon japonicus collection mechanism.

[0043] like Figure 10 As shown, in this embodiment, the first end of the core-removing needle 21 is a sharp conical tip, and the inner diameter is designed to be 1.2 to 1.5 times the diameter of the Ophiopogon japonicus core 52. The outer surface of the core-removing needle 21 and the wall surface of the core-removing channel 53 have a high degree of smoothness. The central axis of the core-removing needle 21 is collinear with the central axis of the conveying channel so that the conical tip of the core-removing needle 21 is directly facing the Ophiopogon japonicus core 52, which facilitates the separation of the Ophiopogon japonicus core 52 from the Ophiopogon japonicus.

[0044] like Figure 10 As shown, in this embodiment of the application, the peeling blade 22 can be positioned directly above the core-removing needle 21. The peeling blade 22 is mounted on a support, and a very small gap is left between the cutting edge of the peeling blade 22 and the outer side of the core-removing needle 21 to ensure that the cutting edge of the peeling blade 22 does not contact the outer side of the core-removing needle 21.

[0045] As an optional embodiment of the Ophiopogon japonicus de-coring device for removing the cores from undone Ophiopogon japonicus 50, the undone Ophiopogon japonicus 50 is poured into hopper 3. After being buffered and shaped by hopper 3, the undone Ophiopogon japonicus 50 enters the conveying mechanism. The undone Ophiopogon japonicus 50 is elongated. The inner diameter of the conveying channel of the conveying mechanism is set to be slightly larger than the outer diameter of the undone Ophiopogon japonicus 50, for example, between 1.1 and 1.3 times the outer diameter of the undone Ophiopogon japonicus 50, so that the conveying channel can only accommodate one undone Ophiopogon japonicus 50 at a time. When the undone Ophiopogon japonicus 50 is conveyed to the de-coring needle 21 by the conveying channel, the core 52 of the Ophiopogon japonicus enters the de-coring channel 53 of the de-coring needle 21 and is pushed towards the outlet of the de-coring channel 53 by subsequent Ophiopogon japonicus cores 52, until it falls into the Ophiopogon japonicus core collection mechanism. The core-removed Ophiopogon japonicus 51 is sleeved on the outside of the core-removing needle 21. When the subsequent core-removed Ophiopogon japonicus 51 is pushed to the peeling knife 22, it is radially cut open on the side facing the peeling knife 22 and peeled off from the core-removing needle 21, and enters the Ophiopogon japonicus collection mechanism.

[0046] The Ophiopogon japonicus de-coring device provided in this application embodiment can de-cored freshly harvested Ophiopogon japonicus after removing fibrous roots and grading by size, or it can moisten dried, graded Ophiopogon japonicus before de-coring. When de-coring uncorked Ophiopogon japonicus 50, the uncorked Ophiopogon japonicus 50 is first poured into the hopper 3, and the conveying mechanism transports the uncorked Ophiopogon japonicus 50 in the hopper 3 to the de-coring mechanism in a single-pass manner. The de-coring needle 21 extends into the conveying channel of the conveying mechanism to remove the Ophiopogon japonicus core 52, and the removed Ophiopogon japonicus core 52 is collected in the de-coring channel 53 and conveyed to the Ophiopogon japonicus core collection mechanism. The de-cored Ophiopogon japonicus 51 passes through the outside of the de-coring needle 21 and is detached from the de-coring needle 21 by the peeling action of the peeling knife 22 before entering the Ophiopogon japonicus collection mechanism. This achieves mechanized de-coring of Ophiopogon japonicus, resulting in high production efficiency, low cost, and mass production of Ophiopogon japonicus de-coring.

[0047] As an optional embodiment, the hopper 3 is a conical hopper, and the inner wall of the hopper 3 is provided with a discharge groove 54, which extends longitudinally. For example... Figure 5 As shown, the conical hopper in this embodiment can buffer the uncorked Ophiopogon japonicus 50, and the feeding trough 54 is located in the lower half of the inner wall of the hopper 3. There can be multiple feeding troughs 54, which are arranged circumferentially along the inner wall of the hopper 3 to initially arrange the uncorked Ophiopogon japonicus 50, so that the uncorked Ophiopogon japonicus 50 can subsequently enter the conveying mechanism in a single arrangement.

[0048] As an optional embodiment, a conveying pipe 5 connects the hopper 3 to the conveying mechanism. A control valve 4 is installed on the conveying pipe 5, and an adjustable frequency vibrator 2 is installed on the outer side of the conveying pipe 5. Figure 5As shown, the control valve 4 can control the speed and quantity of Ophiopogon japonicus entering the conveying pipe 5. The vibration frequency of the adjustable frequency vibrator 2 is adjustable, ensuring that the uncorked Ophiopogon japonicus 50 is discharged smoothly and continuously between the conveying pressure roller group 8 and the conveying support roller group 6, so that the uncorked Ophiopogon japonicus 50 moves steadily and continuously towards the coring needle 21. In this embodiment, the adjustable frequency vibrator 2 can be an adjustable frequency ultrasonic vibrator.

[0049] As an optional embodiment, the conveying roller assembly 6 includes at least two first rollers 7 with first arc-shaped grooves 55 on their sides, and the conveying pressure roller assembly 8 includes at least two second rollers 10 with second arc-shaped grooves 56 on their sides. The at least two first arc-shaped grooves 55 and the at least two second arc-shaped grooves 56 are arranged in a one-to-one correspondence to define the conveying channel. Figure 7 and Figure 9 As shown, the width of the first arc-shaped groove 55 along the axial direction of the first roller 7 and the width of the second arc-shaped groove 56 along the axial direction of the second roller 10 are approximately the same as the average diameter of the uncorrupted Ophiopogon japonicus 50. The width of the second arc-shaped groove 56 is slightly smaller than the width of the first arc-shaped groove 55 so that the uncorrupted Ophiopogon japonicus 50 is in a slightly compressed state in the conveying channel. Through the rolling of the first roller 7 and the second roller 10, the uncorrupted Ophiopogon japonicus 50 is moved forward.

[0050] As an optional embodiment, the conveying pressure roller group 8 is positioned above the conveying support roller group 6 via a positioning bracket 45. The conveying mechanism also includes an adjusting component, which is installed on the conveying pressure roller group 8 or the conveying support roller group 6. The inner diameter of the conveying channel is adjusted by adjusting the distance between the conveying support roller group 6 and the conveying pressure roller group 8. Figure 8 As shown, the adjusting component in this embodiment can be a spring-damped up-and-down adjusting mechanism equipped with a pressure roller adjusting device 9. The pressure roller adjusting device 9 is installed on the conveying roller assembly 6. By rotating the pressure roller of the pressure roller adjusting device 9, the up-and-down movement of the conveying pressure roller assembly 8 is adjusted. During adjustment, based on the average diameter of the uncorrupted Ophiopogon japonicus 50, the distance between the conveying pressure roller assembly 8 and the conveying roller assembly 6 is first adjusted by the pressure roller adjusting device 9, so that the uncorrupted Ophiopogon japonicus 50 is slightly stressed in the conveying channel under the support and pressure of the conveying roller assembly 6 and the conveying pressure roller assembly 8, and can move forward. The adjusting component in this embodiment can also be a lifting mechanism provided on the conveying roller assembly 6. The lifting mechanism adjusts the conveying roller assembly 6 to make the conveying roller assembly 6 move up and down.

[0051] As an optional embodiment, the conveying mechanism further includes a conveying drive motor 2 and a transmission chain 13 driven by the conveying drive motor 2; the conveying roller group 6 includes a first driving wheel and a first driven wheel provided on each of the first rollers 7, with any two adjacent first driven wheels meshing, and the first driving wheel and the first driven wheel being driven connected; the conveying pressure roller group 8 includes a second driving wheel 11 and a second driven wheel 10 provided on each of the second rollers 10, with any two adjacent second driven wheels meshing, and the second driving wheel 11 and the second driven wheel 10 being driven connected; the transmission chain 13 is sleeved on the first driving wheel and the second driving wheel 11. The first driving wheel of the conveying roller group 6 and the second driving wheel 11 of the conveying pressure roller group 8 are connected to the conveying drive motor 2 through the transmission chain 13, so that the conveying roller group 6 and the conveying pressure roller group 8 rotate in the same direction to drive the uncorked Ophiopogon japonicus 50 forward. In this embodiment, the conveying mechanism may also include a tensioning wheel 12 and a variable frequency speed control motor, which cooperate with the transmission chain 13 to jointly drive the first driving wheel and the second driving wheel 11 to rotate.

[0052] like Figure 3 As shown, in this embodiment of the application, the hopper 3, the conveying roller group 6, and the conveying pressure roller group 8 can all be set on an operating table 1, which is stable and reliable.

[0053] As an optional embodiment, the Ophiopogon japonicus collection mechanism includes a connected Ophiopogon japonicus buffer tank 43 and an Ophiopogon japonicus receiving tank 41. The opening of the buffer tank 43 faces the peeling blade 22. A first partition valve 42 is provided at the connection between the receiving tank 41 and the buffer tank 43. At least one of the buffer tank 43 and the receiving tank 41 is connected to a first vacuum generator. The cored Ophiopogon japonicus 51 peeled off by the peeling blade 22 can fall into the buffer tank 43 under gravity. When the buffer tank 43 is connected to the first vacuum generator, the buffer tank 43 is in a low-pressure or vacuum environment, and the peeled cored Ophiopogon japonicus 51 can be sucked in through the opening. When there is a large amount of cored Ophiopogon japonicus 51 in the buffer tank 43, the vacuum tube on the buffer tank 43 is closed, the first partition valve 42 is opened, and the cored Ophiopogon japonicus 51 is discharged to the receiving tank 41. Figure 3 As shown, the opening of the Ophiopogon japonicus buffer tank 43 is provided with a groove-shaped suction nozzle 44. The opening is located at the top of the groove-shaped suction nozzle 44, which can greatly expand the opening area of ​​the Ophiopogon japonicus buffer tank 43 and improve the receiving effect of the de-cored Ophiopogon japonicus 51. Figure 3As shown, an openable observation window 1 is provided in the middle of the Ophiopogon japonicus buffer tank 43, and an openable observation window 2 is provided in the middle of the Ophiopogon japonicus receiving tank 41. A first vacuum generator is connected to the Ophiopogon japonicus buffer tank 43 and the Ophiopogon japonicus receiving tank 41 via a vacuum tube. A valve is provided on the vacuum tube, and an anti-inhalation device 1 is provided at the end of the vacuum tube extending into the Ophiopogon japonicus buffer tank 43, and an anti-inhalation device 2 is provided at the end of the vacuum tube extending into the Ophiopogon japonicus receiving tank 41, to prevent the cored Ophiopogon japonicus 51 from being sucked into the vacuum tube. Vacuum switching between the Ophiopogon japonicus buffer tank 43 and the Ophiopogon japonicus receiving tank 41, as well as the transfer of the cored Ophiopogon japonicus 51, are achieved through the vacuum valve and the vent valve. The bottom of the Ophiopogon japonicus receiving tank 41 is provided with a snap-on quick-opening bottom cover and a vent valve. When it is necessary to discharge the cored Ophiopogon japonicus 51, the first intermediate valve 42 and the vacuum valve are closed, and the vent valve and the snap-on quick-opening bottom cover are opened to discharge the cored Ophiopogon japonicus 51.

[0054] As an optional embodiment, the Ophiopogon japonicus heart collection mechanism includes a connected Ophiopogon japonicus heart buffer tank 33 and an Ophiopogon japonicus heart receiving tank 37. The second end of the core-removing needle 21 extends into the Ophiopogon japonicus heart buffer tank 33. A second diaphragm valve 34 is provided at the connection between the Ophiopogon japonicus heart receiving tank 37 and the Ophiopogon japonicus heart buffer tank 33. At least one of the Ophiopogon japonicus heart buffer tank 33 and the Ophiopogon japonicus heart receiving tank 37 is connected to a second vacuum generator. Ophiopogon japonicus heart 52 can be drawn into the Ophiopogon japonicus heart buffer tank 33 by the pushing action of subsequent Ophiopogon japonicus heart 52. When the Ophiopogon japonicus heart buffer tank 33 is connected to the second vacuum generator, the Ophiopogon japonicus heart buffer tank 33 is in a low-pressure or vacuum environment, and the Ophiopogon japonicus heart 52 can be sucked in through the outlet of the core-removing channel 53. When there is a large amount of Ophiopogon japonicus heart 52 in the Ophiopogon japonicus heart buffer tank 33, the vacuum tube 32 on the Ophiopogon japonicus heart buffer tank 33 is closed, the second diaphragm valve 34 is opened, and the Ophiopogon japonicus heart 52 is discharged to the Ophiopogon japonicus heart receiving tank 37. The Ophiopogon japonicus heart buffer tank 33 is equipped with an openable observation window 29, and a snap-on quick-opening top cover 28 with a locking fastener 26. The second generator is connected to the Ophiopogon japonicus heart buffer tank 33 and the Ophiopogon japonicus heart receiving tank 37 via a vacuum tube 32. A valve is installed on the vacuum tube 32, and an anti-inhalation device 30 is installed at the end of the vacuum tube 32 extending into the Ophiopogon japonicus heart buffer tank 33. An anti-inhalation device 45 is installed at the end of the vacuum tube 32 extending into the Ophiopogon japonicus heart receiving tank 37 to prevent Ophiopogon japonicus heart 52 from being sucked into the vacuum tube 32. Vacuum switching and transfer of Ophiopogon japonicus heart 52 between the Ophiopogon japonicus heart receiving buffer tank and the Ophiopogon japonicus heart receiving tank 37 are achieved through vacuum valve 31 and vent valve 40. The middle part of the Ophiopogon japonicus heart receiving tank 37 is provided with an openable observation window 36, and the bottom is provided with a snap-on quick-opening bottom cover 39 and an emptying valve 40. When it is necessary to discharge the Ophiopogon japonicus heart 52, the second middle partition valve 34 and the vacuum valve 31 are closed, and the emptying valve 40 and the snap-on quick-opening bottom cover are opened to discharge the Ophiopogon japonicus heart 52.

[0055] The first vacuum generator and the second vacuum generator mentioned above can be the same vacuum generator or two different vacuum generators, depending on actual needs.

[0056] The aforementioned Ophiopogon japonicus buffer tank 43, Ophiopogon japonicus receiving tank 41, Ophiopogon japonicus core buffer tank 33 and Ophiopogon japonicus core receiving tank 37 are all supported on the working surface by tank support legs 38.

[0057] As an optional embodiment, the core-removing mechanism further includes a core-removing drive motor 25, which is drivenly connected to the core-removing needle 21 to drive the core-removing needle 21 to rotate along its own central axis. Figure 3 As shown, the core removal drive motor 25 drives the core removal needle 21 via a transmission belt 23 and a pulley 24. A shaft support seat is provided on the core removal needle 21 to ensure the smoothness of its high-speed rotation. A sealing assembly 27 is provided at the connection point with the Ophiopogon japonicus core buffer tank 33 to ensure the vacuum seal of the Ophiopogon japonicus core buffer tank 33. The frequency and speed of the core removal drive motor 25 can be adjusted according to the core removal process of the Ophiopogon japonicus.

[0058] As an optional embodiment, the Ophiopogon japonicus decapitation device also includes a sprayer 46 and a water tank 16 for supplying water to the sprayer 46. The sprayer 46 includes nozzles facing the conveying mechanism. Figure 11 As shown, based on the movement of the uncorked Ophiopogon japonicus 50 between the conveying roller group 8 and the conveying support roller group 6, and on the coring needle 21, the water pump 15 is activated periodically or irregularly to pressurize the water in the water tank 16 to the sprayer 46, performing atomized spraying on the area between the conveying roller group 8 and the conveying support roller group 6, and on the coring needle 21. This washes the equipment and materials, and provides lubrication to ensure smooth conveying of the Ophiopogon japonicus. In this embodiment, the sprayer 46 can be an array-type atomizing sprayer 46, which can effectively improve the spraying effect.

[0059] like Figure 3 As shown, the water pump 15 can be installed in the frame on the operating table 1. The water pump outlet 14 is connected to the pipeline to supply water to the water tank 16. The water tank 16 is equipped with a drain outlet 17, a vent 18 and a water inlet 19, etc., to enable the water tank 16 to work normally.

[0060] like Figure 12 As shown in the embodiments of this application, the Ophiopogon japonicus de-coring device can also be arranged in an array to improve production efficiency and capacity, and realize mass production of Ophiopogon japonicus de-coring.
