Description

Technical Field

[0001] This application relates to the field of sorting machines for Chinese medicinal materials, and in particular to a sorting and cleaning device for Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine emphasizes the use of authentic medicinal materials, as the size and age of the herbs significantly affect their medicinal properties. In actual production, herbs need to be sorted according to size to ensure the stability and reliability of the medicinal properties of the finished product. Before sorting, the herbs must be cleaned to obtain cleaner materials for easier sorting. If the herbs are sorted before cleaning, the reliability of the sorting results will be affected; therefore, a cleaning step is essential before sorting. However, the cleaning process generates a lot of sludge and waste from broken herbs, which is difficult to remove. Similarly, the sorting process also easily generates waste, affecting sorting efficiency and quality, and existing sorting equipment is difficult to clean.

[0003] In Chinese patent literature, patent number CN2020205452307, authorized and announced on December 15, 2020, discloses an automatic sorting device for traditional Chinese medicine decoction pieces, including a sorting tank; a feeding funnel is provided in the upper inner cavity of the sorting tank; a feeding channel coaxially arranged with the bottom of the feeding funnel is connected to the inner cavity of the sorting tank; a rotating shaft is coaxially arranged in the upper inner cavity of the sorting tank; a sieve screen is also fixedly installed inside the sorting tank; the inner cavity of the sorting tank located between the feeding funnel and the sieve screen is a separation chamber; at least four sets of feeding rods are provided on the rotating shaft extending into the separation chamber. Its shortcomings are: the sorting device has a tank-type structure, the sieve screen is not easy to remove, and it cannot be cleaned when waste residue clogs the sieve screen; in addition, its sorting function relies on the sieve screen to complete the removal of waste from the traditional Chinese medicine decoction pieces.

[0004] There is a lack of integrated machines for cleaning and sorting raw materials of Chinese medicinal herbs in the current technology. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, this utility model provides a sorting and cleaning device for traditional Chinese medicine, which sorts and cleans simultaneously, with high sorting efficiency; the screening belt has high working efficiency, does not require frequent disassembly and washing, and cleaning and replacement are also very simple.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution.

[0007] A sorting and cleaning device for traditional Chinese medicine includes a feeding belt and a washing tank. One end of the washing tank has a water inlet. The washing tank includes a large material trough and a small material trough, and an air blower is installed inside the washing tank. A large material discharge belt is installed inside the large material trough. A downwardly inclined feeding belt is installed below the feeding belt, and a screening plate located inside the small material trough is installed at the end of the feeding belt. The screening plate has screening holes, and a small material discharge belt is installed inside the small material trough. Both ends of the screening plate are rotatably connected to the side walls of the small material trough. The middle of the screening plate protrudes downwards, and a lifting mechanism is installed below the screening plate. The end of the washing tank away from the water inlet is connected to a filter chamber via a pipe.

[0008] The feeding belt transports the medicinal herbs, while the screening belt traps large-volume herbs, allowing smaller ones to fall into a smaller trough. A lifting mechanism pushes the screening belt, allowing the larger herbs to fall into a larger trough. The lifting mechanism also shakes the screening belt, facilitating their transfer to the washing tank. This allows for simultaneous cleaning and sorting of the herbs, improving production efficiency. Furthermore, the screening belt is located outside the washing tank, allowing for direct rinsing without disassembly, making cleaning and replacement very convenient. An air-blowing pipe suspends the herbs, and water from the inlet propels them to the other end, simultaneously completing feeding and cleaning without damaging the surface of the herbs, thus improving their utilization efficiency.

[0009] Preferably, the screening belt is arc-shaped. The arc-shaped screening belt can smoothly rebound upwards, thus achieving smooth ejection of the screening belt and facilitating the feeding of large volumes of medicinal materials.

[0010] Preferably, both the large and small material feeding belts are equipped with upward-sloping discharge belts at their ends, and these discharge belts are fitted with spray devices. The discharge belts discharge the medicinal materials, while the spray devices spray water to clean them, thus improving the cleaning efficiency.

[0011] Preferably, several water inlets are arranged in a rectangular array on one side wall of the cleaning tank to ensure stable unidirectional water flow within the cleaning tank.

[0012] Preferably, the lifting mechanism includes a lifting cylinder fixed outside the washing tank and a lifting rod driven by the lifting cylinder. A lifting guide sleeve is provided on the outer side of the washing tank wall to cooperate with the lifting rod. A crossover rod is provided inside the small material trough, connecting to the lifting rod. A lifting rod is mounted on the crossover rod, and the screening belt plate is connected to the lifting rod. The lifting crossover rod is raised and lowered synchronously by controlling the lifting of the lifting rod, thereby driving the lifting rod to rise and fall, completing the control of the convex direction of the screening belt plate. This facilitates the screening of small-volume medicinal materials and the unloading of large-volume medicinal materials, ensuring sorting efficiency.

[0013] Preferably, the screening belt and the lifting rod are connected by a shock-absorbing spring. The shock-absorbing spring plays a role in damping and buffering, improving the reliability of the elastic deformation of the screening belt, and preventing material leakage caused by sudden deformation of the screening belt.

[0014] Preferably, the filter chamber is equipped with a filter screen, with a wastewater chamber and a clean water chamber on either side of the filter screen. A sludge discharge port is located in the wastewater chamber on the side of the filter screen facing the cleaning tank. The filter screen filters the cleaning water, facilitating recycling and improving environmental performance; the sludge discharge port facilitates sludge removal.

[0015] Preferably, the spray system is connected to the clean water chamber via pipes. The water used in the spray system is filtered water from the sewage tank, which can be reused for cleaning, resulting in high cleaning efficiency, low water consumption, and greater environmental friendliness.

[0016] Preferably, the air-blowing pipes are straight, and four evenly spaced air-blowing pipes are provided in the cleaning tank. Each of the four air-blowing pipes has an upward-facing air-blowing hole, and a one-way valve is installed inside the air-blowing pipe. The uniform air-blowing of the four air-blowing pipes ensures reliable suspension and propulsion of the medicinal materials by the air bubbles. The air bubbles drive the water flow, further enhancing the cleaning effect.

[0017] This utility model has the following beneficial effects: it can sort two specifications of medicinal materials; the lifting mechanism can shake the material on the screening belt, making it convenient to feed the material into the washing tank for cleaning. Thus, this application can simultaneously complete the cleaning and sorting of medicinal materials, improving production efficiency. Moreover, the screening belt is located directly outside the washing tank and can be directly rinsed. There is no need to disassemble it during cleaning, making cleaning and replacement very convenient; the air blower suspends the medicinal materials, and the water inlet pushes the medicinal materials to the other end, completing feeding and cleaning at the same time, without damaging the surface of the medicinal materials, thus improving the efficiency of medicinal material use.

[0022] Example

[0023] like Figures 1 to 2As shown, a traditional Chinese medicine sorting and cleaning device includes a feeding belt 1 and a cleaning tank 4. The feeding belt 1 has a downwardly inclined feeding belt 2 at its lower side, and a screening belt plate 3 located within a small material trough 41 at its end. One end of the cleaning tank 4 has a water inlet 43, with several water inlets 43 arranged in a rectangular array on the side wall of one end of the cleaning tank 4. The cleaning tank 4 contains air-blowing pipes 44. The air-blowing pipes 44 are straight, and four air-blowing pipes 44 are evenly spaced within the cleaning tank 4. Each of the four air-blowing pipes 44 has upward-facing air-blowing holes with a spiral axis, providing a spiral propulsion effect for air blowing and improving the anti-clogging ability of the air-blowing holes. A one-way valve is installed within each air-blowing pipe 44. The cleaning tank 4 includes a large material trough 42 and a small material trough 41. One of the four air-blowing pipes 44 is located in the large material trough 42, and the other three are located in the small material trough 41. A large material trough 42 is equipped with a large material discharge belt 45; a small material trough 41 is equipped with a small material discharge belt 46. The large material discharge belt 45 is horizontally positioned, with its two ends spanning the sides of the large material trough 42, and the small material discharge belt 46's two ends spanning the sides of the small material trough 41. The large material discharge belt 45 and the small material discharge belt 46 are located above the aeration pipe 44 in their respective washing tanks 4. Both belts are mesh belts made of stainless steel. The mesh size of the large material discharge belt 45 can be matched to the aperture of the sieve holes, while the mesh size of the small material discharge belt 46 is denser, and millimeter-sized mesh belts can be selected according to actual needs. The function of the small material discharge belt 46 and the large material discharge belt 45 is to prevent the medicinal materials from falling onto the bottom plate of the washing tank 4, acting as a barrier to ensure the aeration effect of the air bubbles on the medicinal materials. The screening belt plate 3 has screening holes inside, and its two ends are rotatably connected to the two side walls of the small material trough 41 respectively; the two ends of the screening belt plate 3 are hinged to the two side walls of the small material trough 41. The middle of the screening belt plate 3 protrudes downward, and the screening belt plate 3 is arc-shaped. A lifting mechanism is provided on the lower side of the screening belt plate 3. The lifting mechanism includes a lifting cylinder 51 fixed outside the washing tank 4 and a lifting rod 52 driven by the lifting cylinder 51. The outer side of the tank wall of the washing tank 4 is provided with lifting guide sleeves 53 that cooperate with the lifting rods 52. Each lifting rod 52 cooperates with two lifting guide sleeves 53, and the two lifting guide sleeves 53 are spaced apart on the tank wall of the washing tank 4. A bridging rod 54 is provided inside the small material trough 41, which is connected to the lifting rod 52. A horizontal first rod 55 is provided at the upper end of the large material trough 42, connecting to the lifting rod 52 on one side of the large material trough 42. The first rod 55 is connected to a vertically arranged second rod 56 inside the small material trough 41, and the second rod 56 is connected to one end of the bridging rod 54. A horizontal third rod 57 is provided at the upper end of the small material trough 41, connecting to the lifting rod 52 on one side of the small material trough 41. A vertically arranged fourth rod 571 is provided inside the small material trough 41, with both ends connected to the third rod 57. A lifting rod 58 is provided on the bridging rod 54, and the screening belt plate 3 is connected to the lifting rod 58. Two lifting rods 58 are provided.The upper and lower ends of the two lifting rods 58 on opposite sides are respectively equipped with rods for connection and fixation to ensure strength. A reinforcing angle plate 541 is provided between the fourth rod 571 and the bridging rod 54, and a reinforcing angle plate 541 is also provided between the second rod 56 and the bridging rod 54. The screening belt plate 3 and the lifting rods 58 are connected by a shock-absorbing spring 59. The end of the washing tank 4 away from the water inlet 43 is connected to the filter chamber through a pipe. The filter chamber is equipped with a filter screen 63, with a sewage chamber 61 and a clean water chamber 62 on both sides of the filter screen 63. A sludge discharge port 64 is provided in the sewage chamber 61 on the side of the filter screen 63 facing the washing tank 4. The ends of the large material feeding belt 45 and the small material feeding belt 46 are both equipped with an upwardly inclined discharge belt 8. The discharge belt 8 is equipped with a waterproof discharge motor, and the discharge belt 8 is moved by the rotation of the discharge motor. The discharge belt 8 is equipped with a spray device. The spray device includes a spray head 7, which is connected to the clean water chamber 62 through a pipe.

[0024] The feeding belt 1 transports the medicinal herbs, while the screening belt 3 intercepts large-volume herbs, allowing smaller-volume herbs to fall into the small trough 41. The lifting mechanism pushes the screening belt 3, allowing large-volume herbs to fall into the large trough 42. The lifting mechanism also shakes the screening belt 3, facilitating the discharge of smaller-volume herbs into the washing tank 4 for cleaning. Thus, this application allows for simultaneous cleaning and sorting of medicinal herbs, improving production efficiency. Furthermore, the screening belt 3 is located directly outside the washing tank 4, allowing for direct rinsing without disassembly, making cleaning and replacement very convenient. The air blower 44 suspends the herbs by blowing air, and the water inlet 43... The unidirectional water outlet at one end of the cleaning tank 4 drives the medicinal materials to move in one direction. Combined with the upward pushing action of the air bubbles in the air blower 44, the medicinal materials are cleaned by the convection of the water. Finally, the cleaned medicinal materials are transported upward out of the cleaning tank 4 through the discharge belt 8. After being sprayed and rinsed by the spray device, they fall from the rear end of the discharge belt 8 onto the horizontally set conveyor belt 9 and are then sent out. The sewage in the cleaning tank 4 flows to the filter chamber for filtration. The sludge accumulates on the left side of the filter screen 63 and can be directly discharged from the sludge discharge port 64. The filtered clean water is recycled through the spray device. After sterilization treatment, the filtered water can also be introduced into the water inlet 43 and recycled in the cleaning tank 4 to improve the utilization efficiency of water resources.
