Description

Technical Field

[0001] This invention belongs to the technical field of traditional Chinese medicine preparation devices and methods, specifically relating to an extraction device and method for preparing traditional Chinese medicine preparations for the prevention and treatment of fruit tree rot. Background Technology

[0002] Traditional Chinese medicine preparations are pharmaceutical forms with specific dosage forms and specifications, made from Chinese medicinal herbs as raw materials and under the guidance of traditional Chinese medicine theory through processes such as processing, compatibility, extraction, and other techniques.

[0003] There are various preparations made from traditional Chinese medicine for fruit tree rot. They usually have multiple functions such as sterilization, wound repair, promoting healing and nutritional rejuvenation. They are favored by green orchards because they have no residue and no drug resistance. The following is an introduction to traditional Chinese medicine preparations. Ulcer-Resistant Agent: This is a traditional Chinese medicine preparation widely used for treating canker and gummosis in fruit trees such as apples, peaches, and kiwis. Its active ingredients include alkaloids and geniposide, which can directly kill bacteria, repair lesions and wounds, and promote healing. Liangguo'an: As another traditional Chinese medicine fungicide, Liangguo'an has triple effects of protection, treatment, and eradication. It is suitable for treating diseases such as rot, ring rot, and anthracnose in various fruit trees, including apples, pears, peaches, and citrus. It can interfere with the synthesis of pathogen cell walls, inhibit spore germination, and at the same time provide nutrients such as amino acids, polysaccharides, and trace elements to enhance the tree's resistance to adverse conditions.

[0004] In the preparation of traditional Chinese medicine preparations, it is often necessary to extract the juice from the inside of the plant, mix it with chemical reagents, and then extract it through distillation. However, when the plant is placed on the support plate, it needs to be spread out manually to facilitate the subsequent uniform extrusion. However, the above operation method reduces work efficiency and is inconvenient to operate manually. At the same time, after the particulate matter on the filter screen is separated from the liquid, an additional power is needed to drive the mechanism to collect the particulate impurities. The structural design is complicated, wastes energy, and is not conducive to environmental protection. Summary of the Invention

[0005] The purpose of this invention is to provide an extraction device and method for preparing herbal preparations for preventing and treating fruit tree rot, in order to solve the technical problem that when plants are placed on a support plate, they need to be laid flat by manual operation to facilitate subsequent uniform extrusion. However, the above-mentioned operation method reduces work efficiency and is inconvenient for manual operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An extraction device for preparing traditional Chinese medicine preparations for the prevention and treatment of fruit tree rot includes: An extrusion preparation mechanism includes a cylinder mounted on a first housing, a piston rod at the bottom of the cylinder extending to a pressure plate, the bottom of the pressure plate movably abutting against a support plate with a guide groove, and a servo motor placed on the first housing connected to one end of the central shaft on the support plate. The output shaft of the servo motor and the rotating wheel are connected by a conveyor belt. One end of the rotating wheel is connected to an eccentric wheel placed on the side wall of the first housing. The outer wall of the eccentric wheel is movably attached to the inclined filter screen. Both sides of the bottom end of the inclined filter screen are connected to the extension end of the side wall of the first housing through compression springs. The bottom two sides of the support plate and the cover plate on the side wall of the first box are connected by a first telescopic rod, and the bottom of the first telescopic rod is provided with a movable shaft that is adapted to the cover plate.

[0007] Furthermore, the outer wall of the pressure plate is connected with a sliding groove along the height direction of the first box, and both ends of the support plate are integrally formed with arc-shaped parts. One end of the inclined filter screen is connected to a collection box placed on the outer wall of the first box through an opening, and the collection box is connected to the first box in a detachable manner.

[0008] Furthermore, a lifting rod is fixedly installed on the top of the inclined filter screen. A cam groove is provided on the outer edge of the lifting rod. The outer wall of the cam groove abuts against the protrusion on the rotating rod. An annular groove is provided on the outer edge of the rotating rod, and one end of the annular groove is fixedly connected to the inner wall of the first box through a guide ring. The rotating rod is connected to the guide ring by rotating.

[0009] Furthermore, a cleaning brush is installed on the top of the rotating rod by adhesive fixation, and an movable hole is opened in the height direction of the inner wall of the rotating rod, penetrating its interior and connecting to the lifting rod.

[0010] Furthermore, it also includes a distillation extraction mechanism, which includes a second box containing a reagent. One end of the second box and the first box are connected to a distillation tank through a conduit on the pump body. A drive motor is fixedly installed on the top of the distillation tank. The output shaft of the drive motor extends and is connected to a reciprocating screw through a rotating shaft. The rotating shaft and the reciprocating screw are connected by a coupling.

[0011] Furthermore, a second telescopic rod is connected to the outer wall of the rotating shaft by a plug-in installation method, a slider fixed on the heating plate is screw-driven on the reciprocating screw, a heater is provided below the heating plate on the inner wall of the second box, and a guide groove is connected to the outer wall of the heating plate along the height direction of the side wall of the second box.

[0012] Furthermore, one end of the heating plate is connected to a fixed rod via a bent rod that penetrates the interior of the distillation tank. One end of the fixed rod has a through hole, and the top of the fixed rod has a vertical hole that connects to the guide tube. A U-shaped block is installed on the movable end of the second telescopic rod. The U-shaped block movably abuts against the push plate. A limit groove is connected to the push plate along the length direction of the limit block at the top of the inner wall of the distillation tank. The limit block and the fixed end of the second telescopic rod are connected by a mounting plate.

[0013] Furthermore, a heat-conducting block is fixedly installed on the inner wall of the distillation tank, and one end of the heat-conducting block is connected to a preheater placed on a guide tube through a vacuum tube.

[0014] The extraction method for preparing traditional Chinese medicine preparations for preventing and treating fruit tree rot includes the following steps: S1.1 Place the required plants on the support plate of the first box, start the cylinder to squeeze out the liquid in the branches by squeezing, and filter it through the inclined filter screen, and deliver it to the distillation box with the help of the tube on the pump body; In steps S1.2 and S1.1, the pump connected to the second tank is started to transport the chemical solution in the second tank to the distillation tank, thereby achieving the mixing effect between the liquids. S1.3 Start the drive motor and drive the rotating shaft and reciprocating screw to rotate. Under the action of screw transmission, the heating plate moves upward and increases the internal temperature of the heating chamber by the work done by the gas, thereby making up for the heat loss of the distillation tank. The rotating shaft drives the rotation of the second telescopic rod and, through the action of resistance, realizes the horizontal movement of the push plate, thereby expanding the stirring area. In steps S1.4 and S1.3, during the movement of the push plate, the turbulence area between the push plate and the mounting plate increases or decreases accordingly. The heat inside the second box is transferred to the preheater through heat transfer, thereby preheating the plant medicine liquid and the chemical medicine liquid.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, to extract the sap from the plant, the plant first enters the support plate inside the first chamber. A servo motor drives the support plate to rotate, causing the material to be evenly spread on the support plate. When the cylinder is activated, the pressure plate effectively presses the plant, causing the sap inside the plant to separate under the pressure. The inclined filter screen can filter and separate the sap from particulate impurities. During the start-up process, the servo motor drives the eccentric wheel on the rotating wheel to rotate via the conveyor belt. Under the action of the moving contact, in conjunction with the compression spring on the inclined filter screen, the inclined filter screen can be driven to vibrate up and down. Combined with the gravity of the particles, they can slide into the collection box, thus completing the automatic collection work. The structure is reasonably designed, with strong integrated performance, simplified manpower, and a high degree of automation.

[0016] In this invention, the inclined filter screen can drive the synchronous movement of the lifting rod during its up-and-down movement. Combined with the cam groove on the lifting rod and the protrusion on the rotating rod, the vertical movement of the lifting rod can be converted into the rotational movement of the rotating rod on the guide ring. Simultaneously, the annular groove on the rotating rod allows it to rotate freely, while the guide ring provides corresponding support. During the rotation of the rotating rod, a cleaning brush can perform a rotational cleaning operation on the bottom of the support plate, ensuring the cleanliness of the support plate. This allows the liquid to flow normally in the guide channel. The first telescopic rod at the bottom of the support plate, combined with the movable shaft on the cover plate, provides support for the support plate and ensures its free rotation through rotation and telescopic movement, improving the stability and safety of the device.

[0017] In this invention, when the plant-based medicinal liquid and the chemical medicinal liquid are mixed in the distillation tank, the drive motor drives the rotating shaft and the reciprocating screw to rotate synchronously. During the rotation of the reciprocating screw, the heating plate can be moved upward, thereby increasing the internal temperature of the heating chamber through gas work, thus compensating for the natural heat loss of the distillation tank. During the rotation, the second telescopic rod on the rotating shaft can expand its extension distance with the help of centrifugal force, thereby making the liquids fully stirred and mixed. During the movement of the movable end on the second telescopic rod, the U-shaped block can be moved to contact the push plate. The mounting plate between the limiting block and the second telescopic rod can position the limiting block, making the limiting block and the push plate rotate synchronously. It can also change the size of the turbulence area between the mounting plate and the push plate, further making the liquid inside the heating chamber fully mixed, improving the distillation effect and product quality.

[0018] The extraction method used in the preparation of traditional Chinese medicine preparations is simple to operate and highly integrated, allowing for full contact between the medicinal liquids. It also enables good control of the internal temperature of the distillation process. Furthermore, the transmission components allow for good regulation of the metering and temperature of the introduced medicinal liquid, and also provide a preheating effect for the liquid entering the system, effectively ensuring the quality of the medicinal liquid.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference manual attached Figure 1 -Appendix Figure 8 As shown, the extraction device for preparing traditional Chinese medicine preparations for preventing fruit tree rot includes: an extrusion preparation mechanism 1, which includes a cylinder 3 mounted on a first housing 2, a piston rod at the bottom of the cylinder 3 extending to a pressure plate 4, and the bottom of the pressure plate 4 movably abutting against a support plate 6 with a guide groove 5. One end of the central shaft on the support plate 6 is connected to a servo motor 7 placed on the first housing 2, and the output shaft of the servo motor 7 and the rotating wheel 8 are connected by a conveyor belt 9. One end of the rotating wheel 8 is connected to an eccentric wheel 10 placed on the side wall of the first housing 2. The outer wall of the eccentric wheel 10 is movably attached to the inclined filter screen 11. Both sides of the bottom end of the inclined filter screen 11 are connected to the extension end of the side wall of the first housing 2 through compression springs 12. Both sides of the bottom end of the support plate 6 and the cover plate on the side wall of the first housing 2 are connected by a first telescopic rod 13. The bottom of the first telescopic rod 13 is provided with a movable shaft 14 that is adapted to the cover plate.

[0024] Specifically, the outer wall of the pressure plate 4 is connected with a sliding groove along the height direction of the first box 2, and both ends of the support plate 6 are integrally formed with arc-shaped parts. One end of the inclined filter screen 11 is connected to a collection box 15 placed on the outer wall of the first box 2 through an opening. The collection box 15 is connected to the first box 2 in a detachable manner.

[0025] To extract the sap from the plant, the plant first enters the support plate 6 inside the first chamber 2. The servo motor 7 drives the support plate 6 to rotate back and forth, so that the material is evenly spread on the support plate 6. When the cylinder 3 is started, the pressure plate 4 can effectively press the plant, so that the sap inside the plant is separated under the pressure. The inclined filter screen 11 can filter and separate the sap and particulate impurities. During the start-up process, the servo motor 7 drives the eccentric wheel 10 on the rotating wheel 8 to rotate through the conveyor belt 9. Under the action of the moving contact, in conjunction with the compression spring 12 on the inclined filter screen 11, the inclined filter screen 11 can be driven to vibrate up and down. Combined with the gravity of the particles, they can slide into the collection box 15, thus completing the automatic collection work. The structure is reasonably designed, with strong integrated performance, simple manpower, and high degree of automation.

[0026] The chemical and herbal solutions used in traditional Chinese medicine for preventing and treating fruit tree rot are prepared in the following proportions by weight: Wound protectant: 16 parts rosin; 2 parts lard; 6 parts alcohol; 1 part rosin oil. The chemical solution is alcohol, and the rosin oil is obtained by extrusion. The two are then mixed and stirred.

[0027] Instructions for use: First, heat the lard until melted, then add rosin powder and melt it. Remove from heat and let cool. Then slowly add alcohol and rosin oil, stirring well. It can be used to seal wounds after grafting or scraping away rot.

[0028] The above-mentioned drug mixture is just one of the conventional technical means for those skilled in the art, and has not been described in detail here, but does not affect the effective implementation of the technical solution of the present invention.

[0029] The inclined filter screen 11 has an opening at one end, which can be opened and closed by an electric push rod assembly in conjunction with a baffle. The electric push rod assembly is a conventional technical means for those skilled in the art. Although there are no corresponding drawings, it does not affect the effective implementation of the technical solution of the present invention.

[0030] A lifting rod 16 is fixedly installed on the top of the inclined filter screen 11. A cam groove 17 is formed on the outer edge of the lifting rod 16. The outer wall of the cam groove 17 abuts against the protrusion 19 on the rotating rod 18. An annular groove 20 is formed on the outer edge of the rotating rod 18, and one end of the annular groove 20 is fixedly connected to the inner wall of the first housing 2 through a guide ring 21. The rotating rod 18 is connected to the guide ring 21 by rotation. A cleaning brush 22 is installed on the top of the rotating rod 18 by adhesive fixation. An movable hole is formed in the height direction of the inner wall of the rotating rod 18, penetrating its interior and connecting to the lifting rod 16.

[0031] The inclined filter 11 can drive the synchronous movement of the lifting rod 16 during its up-and-down movement. In conjunction with the cam groove 17 on the lifting rod 16 and the protrusion 19 on the rotating rod 18, the vertical movement of the lifting rod 16 can be converted into the rotational movement of the rotating rod 18 on the guide ring 21. At the same time, the annular groove 20 on the rotating rod 18 allows the rotating rod 18 to rotate freely, and the guide ring 21 can provide corresponding support force to the rotating rod 18. During the rotation of the rotating rod 18, the bottom of the support plate 6 can be cleaned by the cleaning brush 22, thereby ensuring the cleanliness of the support plate 6. This allows the liquid to flow normally in the guide channel 5. The first telescopic rod 13 at the bottom of the support plate 6, together with the movable shaft 14 on the cover, can not only provide corresponding support for the support plate 6, but also ensure the free rotation of the support plate 6 through rotation and telescopic means, which improves the stability of the device and enhances its safety performance.

[0032] The extraction device for preparing traditional Chinese medicine preparations for preventing and treating fruit tree rot also includes a distillation extraction mechanism 23. The distillation extraction mechanism 23 includes a second box 24 containing the medicine. One end of the second box 24 and the first box 2 are connected to a distillation tank 26 through a conduit 25 on the pump body. A drive motor 27 is fixedly installed on the top of the distillation tank 26. The output shaft of the drive motor 27 extends and is connected to a reciprocating screw 29 through a rotating shaft 28. The rotating shaft 28 and the reciprocating screw 29 are connected by a coupling.

[0033] The outer wall of the rotating shaft 28 is connected to the second telescopic rod 30 by plug-in installation. The reciprocating screw 29 has a slider 32 fixed on the heating plate 31. Below the heating plate 31 is a heater 33 placed on the inner wall of the second box 24. The outer wall of the heating plate 31 is connected to a guide groove along the height direction of the side wall of the second box 24.

[0034] One end of the heating plate 31 is connected to a fixed rod 34 via a bent rod that penetrates the interior of the distillation tank 26. One end of the fixed rod 34 has a through hole 35, and the top of the fixed rod 34 has a vertical hole that connects to the guide tube 25. A U-shaped block 36 is installed on the movable end of the second telescopic rod 30. The U-shaped block 36 movably abuts against the push plate 37. A limiting groove is connected to the push plate 37 along the length direction of the limiting block 38 at the top of the inner wall of the distillation tank 26. The limiting block 38 and the fixed end of the second telescopic rod 30 are connected by a mounting plate 39.

[0035] The limiting block 38 is fixed to the fixed end of the second telescopic rod 30 by the mounting plate 39. This allows the push plate 37 to rotate freely with the limiting block 38 and also allows the push plate 37 to move freely horizontally on the limiting block 38. Moreover, during the horizontal movement of the push plate 37, the turbulence area between the push plate 37 and the mounting plate 39 changes and adjusts accordingly, thereby changing the turbulence area of ​​the rotation and ensuring full contact between the liquid medicine.

[0036] Specifically, a heat-conducting block 40 is fixedly installed on the inner wall of the distillation tank 26. One end of the heat-conducting block 40 is connected to a preheater 42 placed on the guide tube 25 through a vacuum tube 41. When the heating plate 31 moves upward, the through hole 35 on the fixing rod 34 moves upward accordingly, opening or expanding the liquid inlet flow rate, so that the liquid volume matches the heating temperature.

[0037] Reference manual attached Figure 9 The extraction method for preparing traditional Chinese medicine preparations for the prevention and treatment of fruit tree rot includes the following steps: S1.1 Place the required plant on the support plate 6 of the first box 2, start the cylinder 3 to squeeze out the liquid in the branches by squeezing, and filter it through the inclined filter screen 11, and transport it to the distillation box 26 with the help of the conduit 25 on the pump body. In steps S1.2 and S1.1, the pump connected to the second tank 24 is started, thereby transporting the chemical solution in the second tank 24 to the distillation tank 26, thereby achieving the mixing effect between the liquids; S1.3 Start the drive motor 27 and drive the rotating shaft 28 and reciprocating screw 29 to rotate. Under the action of screw transmission, the heating plate 31 moves upward and increases the internal temperature of the heating chamber by the work of gas, thereby compensating for the heat loss of the distillation tank 26. The rotating shaft 28 drives the second telescopic rod 30 to rotate and, through the action of resistance, realizes the horizontal movement of the push plate 37, thereby expanding the stirring area. In steps S1.4 and S1.3, during the movement of the push plate 37, the turbulence area between the push plate 37 and the mounting plate 39 increases or decreases accordingly. The heat inside the second box 24 is transferred to the preheater 42 through heat transfer, thereby preheating the plant medicine liquid and the chemical medicine liquid.

[0038] The extraction method used in the preparation of traditional Chinese medicine preparations is simple to operate and highly integrated, allowing for full contact between the medicinal liquids. It also enables good control of the internal temperature of the distillation process. Furthermore, the transmission components allow for good regulation of the metering and temperature of the introduced medicinal liquid, and also provide a preheating effect for the liquid entering the system, effectively ensuring the quality of the medicinal liquid.

The rotating shaft (28) drives the second telescopic rod (30) to rotate and, through the action of resistance, realizes the horizontal movement of the push plate (37), thereby expanding the stirring area. In steps S1.4 and S1.3, during the movement of the push plate (37), the turbulence area between the push plate (37) and the mounting plate (39) increases or decreases accordingly. The heat inside the second box (24) is transferred to the preheater (42) by heat transfer, so that the plant medicine liquid and chemical medicine liquid are preheated.
