Description

Technical Field

[0001] This invention relates to the field of medicinal herb cleaning technology, and particularly to medicinal herb cleaning equipment and methods. Background Technology

[0002] In the field of traditional Chinese medicine processing, medicinal materials usually need to be cleaned first. A herb washing machine is a device that can automatically clean medicinal materials, replacing manual cleaning by workers and making the process more convenient and efficient.

[0003] Currently, most common herb washing machines on the market mainly use a conveyor to carry Chinese medicinal herbs forward and use high-pressure water jets to rinse the herbs during the process, thereby achieving the cleaning effect.

[0004] However, when cleaning root-type Chinese medicinal materials, existing washing machines are ineffective because these materials have many long and thin roots. Simply rinsing with high-pressure water is not only ineffective in removing dirt and grime from the roots, but it also easily breaks the roots, damaging the medicinal materials. Furthermore, these roots tend to tangle together, making them prone to breakage and resulting in waste of the medicinal materials. Summary of the Invention

[0005] This application provides a medicine washing device and a medicine washing method, which can solve the problems of poor cleaning effect and easy breakage of roots and fibrous Chinese medicinal materials when the existing medicine washing machine is used to clean them.

[0006] This application provides a medicine washing device, including a medicine washing cylinder, which is a hollow cylinder with its central axis along the horizontal direction. The medicine washing cylinder is provided with a water inlet and an openable and closable drain outlet at the lower end. A filter screen for filtering out impurities is provided at the drain outlet. An openable and closable medicine outlet is provided on the upper side of the medicine washing cylinder. Two rigid mesh clamping plates are rotatably arranged in the medicine washing cylinder, and their rotation axes are both along the central axis of the medicine washing cylinder. A clamping component is provided between the two clamping plates to adjust the distance between the two clamping plates so as to clamp or loosen root and fibrous medicinal materials between the two clamping plates. A first motor is provided to drive the clamping plates to rotate. Soft clamping elements are provided on two adjacent surfaces of the two clamping plates to contact and clamp the medicinal materials in the middle from both sides.

[0007] In one embodiment, the clamping component includes a first mounting plate, which is arranged along the length of the clamping plates. The first mounting plate is located on the side of one of the clamping plates away from the other clamping plate and is spaced apart from the clamping plates. A first connecting plate extends from the clamping plate away from the other clamping plate and is connected to the clamping plate through the first connecting plate. A plurality of first threaded holes are arranged along the length of the first mounting plate, and a first bolt is screwed into each of the first threaded holes. By tightening the first bolt against the clamping plate it is close to, the medicinal material between the two clamping plates is clamped.

[0008] In one embodiment, the first mounting plate is rotatably connected to the drug clamping plate that is furthest away from it via the first connecting plate, with the axis of rotation parallel to the length direction of the first mounting plate.

[0009] In one embodiment, a second mounting plate is further fixed on the first mounting plate, and a first spring is arranged between the second mounting plate and the first bolt along the axis of the first bolt. One end of the first spring is connected to the second mounting plate, and the other end is connected to a pressure plate. The pressure plate contacts the nut of the first bolt to provide a clamping effect on the first spring.

[0010] In one embodiment, a set of soft clamping elements is provided on two adjacent surfaces of the two clamping plates. Each set of clamping elements includes several first rubber seats and several second rubber strips. The length directions of the first rubber seats and the second rubber strips are both along the length direction of the clamping plate. The first rubber seats are located on the side of the clamping plate away from its axis of rotation. The first rubber seats on the two clamping plates are respectively used to contact the roots of root-like medicinal materials from both sides, and form a clamping effect on the roots of root-like medicinal materials as the two clamping plates approach each other. The several second rubber strips are arranged along the width direction of the clamping plate between the first rubber seats and the axis of rotation of the clamping plate. The second rubber strips farther away from the axis of rotation of the clamping plate are thicker. When the first rubber seats clamp the roots, the second rubber strips on the two clamping plates contact the roots from both sides and form a clamping effect on the roots.

[0011] In one embodiment, a short shaft is fixed at the pivot of each of the medicine clamping plates, and the two short shafts are arranged on the left and right, with their central axes coinciding with the pivot of the medicine clamping plate. The two short shafts are rotatably connected to each other, and the pivot is along its central axis. One of the short shafts is connected to the first motor and is driven to rotate by the first motor.

[0012] In one embodiment, the dispensing port is located on the side of the washing cylinder, and the lower end of the dispensing port is located at the height of the rotating shaft of the clamping plate. A first opening and closing plate is slidably disposed at the dispensing port, and the first opening and closing plate can slide to completely cover the dispensing port or remove the dispensing port.

[0013] In one embodiment, the filter screen is detachably connected to the drain outlet.

[0014] A method for washing medicinal roots includes the following steps:

[0015] S1. Open the medicine dispensing port on the medicine washing tube, and place the root-like medicinal materials one by one along the length of the medicine clamping plate on one of the medicine clamping plates;

[0016] S2. Adjust the distance between the two clamping plates by using the clamping assembly to make the clamping parts contact and clamp the root-like medicinal materials from both sides;

[0017] S3. Close the medicine outlet and release water into the medicine washing cylinder from the water inlet;

[0018] S4. The two clamping plates are driven to rotate in the washing tube by the first motor, so that the root-like medicinal materials are washed in the water as they rotate.

[0019] S5. After cleaning, open the drain to drain the water, and then open the medicine outlet to remove the medicinal materials.

[0020] A method for washing medicinal materials includes the following steps:

[0021] S1. Open the medicine dispensing port on the medicine washing tube, so that the medicine clamping plate is located on the upper side of the medicine washing tube, and pour the medicine into the medicine washing tube;

[0022] S2. Close the medicine dispensing port and release water into the medicine washing cylinder from the water inlet, so that the water level rises to the height of the medicine clamping plate pivot.

[0023] S3. The first motor drives the two medicine clamping plates to rotate clockwise into the water and stops them when they are about to come out of the water.

[0024] S4. The first motor is reversed to rotate the two medicine clamping plates 540° counterclockwise.

[0025] S5. Then the first motor rotates forward another 540°;

[0026] S6. Repeat S4-S5 until the herbs are clean;

[0027] S7. The medicine clamping plate carries the medicine to the water surface near the medicine dispensing port;

[0028] S8. Open the drain outlet to drain the water, then open the medicine outlet and take out the medicinal materials.

[0029] In summary, the washing equipment and method in this application have the following advantages compared to the prior art:

[0030] (1) The clamping plate carries the root-like medicinal materials and rotates them in the washing tube, so that every part of the root-like medicinal materials can fully contact the relatively flowing water, so that the root-like medicinal materials can be cleaned during the rotation in the water, the cleaning effect is better and the roots are not easily broken; the root-like medicinal materials are arranged one by one and clamped on the clamping plate, so that their roots will not be tangled together during the cleaning process, avoiding the waste of medicinal materials caused by the roots being tangled and broken;

[0031] (2) The clamping component can protect the medicinal materials and can adapt to different sizes of the medicinal materials within a certain range through deformation. As the distance between the two clamping plates decreases, the root medicinal materials are clamped by appropriate pressure and greater friction.

[0032] (3) Using a washing method for medicinal materials, non-root medicinal materials can be washed by constantly moving the medicinal materials back and forth in the water, resulting in a better washing effect. Attached Figure Description

[0047] Please see Figure 1A washing device includes a washing cylinder 11, which is a hollow cylinder with its central axis along a horizontal direction. A support base 1 is fixedly mounted on the lower side of the washing cylinder 11, and the cylinder is fixed to the ground by the support base 1. The washing cylinder 11 and the support base 1 are fixedly connected by welding, and the support base 1 is fixed to the ground by anchor bolts.

[0048] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 The washing cylinder 11 has a water inlet 2 at its upper end, and a water pipe 3 is connected to the water inlet 2 to supply water to the washing cylinder 11. The washing cylinder 11 has an openable and closable drain outlet 4 at its lower end. The opening and closing structure here can refer to the conventional setting of the drain outlet 4 of the water tank commonly used in the prior art (such as a gate valve 6 or a gate structure).

[0049] Please see Figure 6 The lower end of the drain outlet 4 is provided with a filter screen plate 12 for filtering out impurities, which can filter out medicinal residue and other impurities in the water during the drainage process. In one embodiment, a first mounting groove 5 is provided on the side wall of the drain outlet 4, which is horizontally connected to the inside and outside of the groove. The filter screen plate 12 is slidably connected to the first mounting groove 5, and can slide into or out of the drain outlet 4 through the first mounting groove 5. When the filter screen plate 12 enters the first mounting groove 5, it can be fixed by a threaded connection. When the filter screen plate 12 needs to be removed, simply unscrew the bolts at this location. This makes the filter screen plate 12 detachable at the drain outlet 4. When the medicinal residue or impurities filtered by the filter screen plate 12 accumulate to a certain extent, the filter screen plate 12 can be removed for cleaning to ensure its filtration effect. Furthermore, a first handle 13 is also fixed on the filter screen plate 12, which is convenient for workers to pull it out or push it in.

[0050] Please see Figure 5 , Figure 7 The washing cylinder 11 has an openable and closable medicine outlet 7 on its upper side for workers to put in and take out medicinal materials. Two rigid mesh clamping plates 14 are rotatably installed in the washing cylinder 11, and their rotation axes are both along the central axis of the washing cylinder 11, for stirring in the washing cylinder 11.

[0051] A clamping component is provided between the two clamping plates 14 to adjust and maintain the distance between the two clamping plates 14, so as to clamp or loosen the root-like medicinal materials between the two clamping plates 14. A first motor 26 is provided to drive the clamping plates 14 to rotate. The clamping plates 14 carry the root-like medicinal materials and rotate in the washing tube 11, so that every part of the root-like medicinal materials can fully contact the relatively flowing water, so that the root-like medicinal materials are cleaned during the rotation in the water. The cleaning effect is good and the roots 33 are not easily broken. The root-like medicinal materials are arranged one by one and clamped on the clamping plates 14 so that their roots 33 will not tangle together during the cleaning process, avoiding waste of medicinal materials caused by the roots 33 tangling and breaking.

[0052] The two clamping plates 14 are each provided with a soft clamping element on two adjacent surfaces, which are used to contact and clamp the medicinal material in the middle from both sides. In this way, the clamping element can protect the medicinal material and can adapt to different sizes of the medicinal material within a certain range through deformation. As the distance between the two clamping plates 14 decreases, the root medicinal material is clamped by appropriate pressure and greater friction.

[0053] Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 In one embodiment, the clamping component includes a first mounting plate 19, which is arranged along the length of the clamping plates 14. The first mounting plate 19 is located on the side of one of the clamping plates 14 away from the other, and there is a gap between it and the clamping plates 14. Both ends of the first mounting plate 19 extend towards the clamping plate 14 away from it and are fixedly provided with first connecting plates 20, which are connected to the clamping plate 14. A plurality of first threaded holes 21 are arranged along its length on the first mounting plate 19, and the first threaded holes 21 are facing the clamping plates 14. A first bolt 22 is screwed into each of the first threaded holes 21. By turning the first bolt 22 against the clamping plate 14 it is close to, the gap between the two clamping plates 14 is adjusted, thereby clamping the medicine between the two clamping plates 14. This configuration is easy to implement and relatively simple to operate.

[0054] Please see Figure 8 , Figure 10In one embodiment, the first mounting plate 19 is rotatably connected to the adjacent medicine clamping plate 14 via the first connecting plate 20, with the axis of rotation parallel to the length direction of the first mounting plate 19. This configuration allows the first bolt 22 to be adjusted to be perpendicular to the adjacent medicine clamping plate 14 by rotating the first mounting plate 19, ensuring that the bottom surface of the first bolt 22 is in contact with the medicine clamping plate 14, resulting in a more stable effect.

[0055] Please see Figure 8 , Figure 10 In one embodiment, a second mounting plate 23 is also fixed to the first mounting plate 19 by welding. The second mounting plate 23 is located on the side of the first mounting plate 19 opposite to the washing plate. A first spring 24 is arranged between the second mounting plate 23 and the first bolt 22 along the axial direction of the first bolt 22. One end of the first spring 24 is fixedly connected to the second mounting plate 23 by welding, and the other end is fixedly connected to a pressure plate 25. The pressure plate 25 contacts the nut of the first bolt 22 to provide a clamping effect on the first spring 24 along its axial direction after it has been adjusted, thus preventing excessive rotation of the first bolt 22 after adjustment, which would affect the clamping effect on the root-like medicinal materials during the cleaning process. Furthermore, there are multiple first springs 24 arranged along the length of the clamping plate 14, resulting in a more stable structure.

[0056] Please see Figure 3 , Figure 4 , Figure 8 , Figure 10In one embodiment, a set of soft clamping elements is provided on two adjacent surfaces of the two clamping plates 14. Each set of clamping elements includes a first rubber seat 28 and multiple second rubber strips 29. The length directions of the first rubber seat 28 and the second rubber strips 29 are both along the length direction of the clamping plate 14. The first rubber seat 28 is located on the side of the clamping plate 14 away from its axis of rotation. The first rubber seats 28 on the two clamping plates 14 are respectively used to contact the roots 32 of the root-like medicinal materials from both sides, and form a clamping effect on the roots 32 of the root-like medicinal materials as the two clamping plates 14 approach each other. Multiple second rubber strips 29 are arranged along the width direction of the clamping plate 14 between the first rubber seat 28 and the pivot of the clamping plate 14. The second rubber strips farther away from the pivot of the clamping plate 14 are thicker (because when the two clamping plates 14 are not closed, the closer to the pivot of the clamping plate 14, the smaller the spacing). When the first rubber seat 28 clamps the root 32, the second rubber strips 29 on the two clamping plates 14 contact the root hairs 33 from both sides and clamp the root hairs 33. In this arrangement, the first rubber seat 28 and the second rubber strips 29 respectively contact and clamp the root 32 and root hairs 33 of the root-type medicinal material, so that the root hairs 33 will not swing around during the cleaning process, and the effect is more stable. Preferably, on two adjacent surfaces of the two first rubber seats 28, multiple recessed areas 30 are equidistantly arranged along the length of the medicine clamping plate 14. The positions of the multiple recessed areas 30 on the two first rubber seats 28 are one-to-one corresponding, and each pair of corresponding recessed areas 30 is used to place the root 32 of a root-like medicinal material. This arrangement improves the effect. Furthermore, the width of the second rubber strip 29 can be as small as possible.

[0057] Please see Figure 8In one embodiment, each of the medicine clamping plates 14 has a short shaft 15 fixed at its pivot point by welding. The length of a single short shaft 15 is approximately half the length of the medicine clamping plate 14. Two short shafts 15 are arranged one on the left and one on the right, with their central axes coinciding with the pivot point of the medicine clamping plate 14. The two short shafts 15 are rotatably connected, with the pivot point along their central axis. Two second mounting grooves are recessed on the inner wall of the medicine washing cylinder 11. The ends of the two short shafts 15 that are far apart are respectively inserted into and rotatably connected to the two mounting grooves to provide support. On two adjacent surfaces of the two short shafts 15, one has an annular protrusion fixed around its center, and the other has a corresponding annular recess. The rotatable connection between the two short shafts 15 is achieved by inserting the annular protrusion into the annular recess. One of the short shafts 15 is connected to the output shaft of the first motor 26 (or it can be a conventional transmission setting such as gear transmission or belt transmission), and is driven to rotate by the first motor 26. The housing of the first motor 26 is fixed on the support base 1.

[0058] Please see Figure 1 In one embodiment, the dispensing port 7 is located on the side of the washing cylinder 11, occupying approximately half of the upper half of the washing cylinder 11, and the lowest point of the dispensing port 7 is slightly higher than the pivot point of the clamping plate 14. A first opening and closing plate 8 is slidably disposed at the dispensing port 7. The first opening and closing plate 8 is an arc-shaped plate that slides along the direction of contact with the side wall of the washing cylinder 11. Both sides of the first opening and closing plate 8 are provided with sliding grooves 10 along the sliding direction of the first opening and closing plate 8 to provide support for the sliding of the first opening and closing plate 8. It can slide to completely cover the dispensing port 7 or move the dispensing port 7 away, thereby realizing the opening and closing of the dispensing port 7. The structure is easy to implement and relatively simple to operate. Furthermore, when the dispensing port 7 is closed, its position can be fixed by a pin structure 9 to make it more stable. The pin structure 9 is prior art, and its specific structure will not be described in detail here.

[0059] Please see Figure 7 A method for washing medicinal roots includes the following steps:

[0060] S1. Open the medicine outlet 7 on the medicine washing tube 11, and place the root-type medicinal materials one by one along the length of the medicine clamping plate 14 on one of the medicine clamping plates 14;

[0061] S2. Adjust the distance between the two clamping plates 14 by using the clamping assembly to make the clamping parts contact and clamp the root-like medicinal materials from both sides;

[0062] S3. Close the medicine outlet 7 and release water into the medicine washing cylinder 11 from the water inlet 2, so that the water level roughly reaches the pivot of the medicine clamping plate 14;

[0063] S4. The first motor 26 drives the two clamping plates 14 to rotate in the washing cylinder 11, so that the root medicinal materials are washed in water as they rotate.

[0064] S5. After cleaning, open the drain port 4 to drain the water, and open the medicine outlet 7 to remove the medicine on the medicine clamping plate 14.

[0065] This method is applicable to the aforementioned washing equipment.

[0066] Please see Figure 7 A method for washing medicinal materials includes the following steps:

[0067] S1. Open the medicine outlet 7 on the medicine washing tube 11, so that the medicine clamping plate 14 is located on the upper side of the medicine washing tube 11, and pour the medicine into the medicine washing tube 11;

[0068] S2. Close the medicine outlet 7 and release water into the medicine washing cylinder 11 from the water inlet 2, so that the water level rises to the height of the shaft of the medicine clamping plate 14;

[0069] S3. The first motor 26 drives the two medicine clamping plates 14 to rotate clockwise into the water and stops when they are about to come out of the water. At this time, the medicine is located between the medicine clamping plates 14 and the water surface.

[0070] S4. By reversing the first motor 26, the two medicine clamping plates 14 are rotated 540° counterclockwise, pushing the medicine to the water surface on the other side from the opposite direction.

[0071] S5. Then the first motor 26 rotates forward 540°;

[0072] S6. Repeat S4-S5, repeatedly pushing the herbs in the water to rinse them until they are clean;

[0073] S7. The medicine clamping plate 14 carries the medicine to the water surface near the medicine dispensing port 7;

[0074] S8. Open the drain outlet 4 to drain the water, then open the medicine outlet 7 and take out the medicinal materials.

[0075] This method is mainly applicable to cleaning non-root medicinal materials using the above-mentioned washing equipment. It allows the medicinal materials to be constantly moved back and forth in the water, resulting in a better cleaning effect.
