Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb harvesting technology, and in particular to a harvesting device for Epimedium. Background Technology

[0002] Epimedium, a common perennial herb in traditional Chinese medicine, primarily derives its medicinal value from the leaves and stems of its above-ground parts. In actual production, the above-ground parts of mature plants need to be harvested. Currently, the industry mainly uses two methods for harvesting Epimedium: manual harvesting and small-scale mechanical harvesting. Manual harvesting typically involves using tools such as sickles and scissors to cut the above-ground parts of each plant. After harvesting, the leaves and stems are separated manually, and the leaves are further screened to remove impurities. This method is suitable for small-scale planting. Large-scale planting often uses general-purpose small-scale herb harvesting equipment. This equipment typically uses rotating blades to cut the plants and then sends the cut material into a collection box, completing the harvesting and initial collection process.

[0003] However, existing harvesting methods have significant limitations in practical applications and are difficult to adapt to the specific needs of Epimedium processing. The integrated manual harvesting and sorting process is cumbersome, inefficient, and has high labor costs. Furthermore, the consistency of manual sorting is poor, making it difficult to ensure the accuracy of leaf screening. General-purpose small harvesting equipment can only achieve whole harvesting and collection of materials and cannot separate leaves and stems during the harvesting process. This requires additional subsequent separation steps, increasing processing costs and operating cycles. At the same time, existing equipment lacks switchable operating modes and cannot flexibly select whole harvesting or stem-leaf separation harvesting according to actual processing needs. This results in insufficient adaptability, and some of the materials collected by the equipment contain small stems and impurities, requiring secondary manual screening, which further reduces operating efficiency. Summary of the Invention

[0004] This application discloses a harvesting device for Epimedium to solve the technical problems of low harvesting efficiency and inability to separate stems and leaves in existing Epimedium harvesting methods in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] This invention provides a harvesting device for Epimedium, comprising a frame, a cutting mechanism, a sorting component, a collecting component, a screening component, and a mode switching mechanism. The cutting mechanism is mounted at the front end of the frame, and the sorting component is mounted behind the cutting mechanism and fixed to the frame. The sorting component includes a vibration sorting module and a wind-powered sorting module. The vibration sorting module is positioned corresponding to the discharge end of the cutting mechanism, and the wind-powered sorting module is positioned at the discharge end of the vibration sorting module. The collecting component includes a leaf collecting box and a stem collecting box, both mounted in the middle of the frame. The blade collection box is positioned corresponding to the discharge end of the wind-powered sorting module, and the stalk collection box is positioned below the blade collection box, forming a drop guide with the discharge end of the vibration sorting module. The screening assembly is installed inside the blade collection box and includes a screen and a fixing frame. The fixing frame is connected to the inner wall of the blade collection box, and the screen is mounted on the fixing frame. The mode switching mechanism includes a switching baffle and a driving component. The switching baffle is rotatably installed between the wind-powered sorting module and the blade collection box, and the driving component is connected to the switching baffle to drive the switching baffle to open and close.

[0007] Preferably, the wind-powered sorting module includes a fan, an air guide hood, and an air speed regulator. The air guide hood is provided corresponding to the discharge end of the vibration sorting module. The fan is connected to the air guide hood, and the air speed regulator is electrically connected to the fan. The vibration sorting module includes a vibration sorting chamber and a vibration frame disposed in the vibration sorting chamber. The vibration sorting chamber is connected to the air guide hood, and a baffle mesh plate is slidably disposed between the vibration sorting chamber and the air guide hood.

[0008] Preferably, the cutting mechanism includes a cutting blade assembly, a blade shaft, and a drive motor. The blade shaft is rotatably mounted on the front end of the frame, the cutting blade assembly is fixed on the blade shaft, the output shaft of the drive motor is rotatably connected to the blade shaft, and the cutting blade assembly is evenly distributed along the circumference of the blade shaft.

[0009] Preferably, the air guide shroud has a trumpet-shaped structure, with the end near the vibration sorting module being the feed inlet and the end away from the vibration sorting module being the air outlet. The diameter of the air outlet is smaller than the diameter of the feed inlet. The wind speed regulating component is a speed regulating valve connected in series with the air inlet pipe of the blower.

[0010] Preferably, both the leaf collection box and the stem collection box are box structures with open tops. The side walls of the leaf collection box are provided with ventilation holes, and the bottom of the stem collection box is provided with an anti-slip pad and is connected to the frame by a drawer-type sliding connection.

[0011] Preferably, the screen is inclined, and a buffer spring is provided on the fixing frame. One end of the buffer spring is connected to the fixing frame, and the other end abuts against the screen.

[0012] Preferably, the driving component of the mode switching mechanism is a miniature cylinder or a stepper motor. The driving component is fixed on the frame, and its output end is connected to the switching baffle. When the switching baffle is fully closed, it blocks the air outlet of the air guide shroud, allowing the cut material to fall directly into the stalk collection box.

[0013] Preferably, a guide plate is provided between the cutting mechanism and the sorting component. The guide plate is fixed on the frame and is inclined downwards, with one end corresponding to the discharge end of the cutting blade assembly and the other end extending to the feed inlet of the vibration sorting module.

[0014] The technical solution adopted in this invention can achieve the following beneficial effects:

[0015] This invention achieves integrated harvesting and stem-leaf separation of Epimedium through the coordinated operation of a cutting mechanism, a vibration sorting module, and a wind-powered sorting module. After the cutting mechanism cuts the entire plant, the material enters the vibration sorting module via a guide plate, where vibration initiates initial loosening and size separation. The material then enters the wind-powered sorting module, utilizing the density and mass differences between Epimedium leaves and stems. An adjustable airflow blows the lighter leaves to a leaf collection box, while the heavier stems fall into the stem collection box below, effectively separating the stems and leaves. An inclined screen in the screening assembly further filters the leaves, removing small stem fragments and ensuring leaf purity. The mode-switching mechanism allows the device to flexibly switch operating modes according to actual needs: when mixed stem and leaf collection is required, the drive unit closes the switching baffle, blocking the wind-powered sorting path, and the material falls directly into the stem collection box; when stem and leaf separation is required, the switching baffle opens, initiating the complete sorting process. This mechanical sorting scheme avoids the inefficiency of traditional manual sorting and the impact of chemical treatment methods on the quality of medicinal materials, significantly improving harvesting efficiency. At the same time, it ensures the integrity and cleanliness of Epimedium leaves or other effective medicinal parts, providing high-quality raw materials for subsequent drying and processing. The drawer-type sliding connection collection box design facilitates quick unloading and cleaning. The overall structure is compact and easy to operate, making it particularly suitable for large-scale harvesting of Epimedium in forest planting environments. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The following is in conjunction with the appendix Figures 1 to 2 The present application provides a detailed description of a harvesting device 1 for Epimedium through specific embodiments and application scenarios.

[0027] This invention provides a harvesting device 1 for Epimedium, comprising a frame 10, a cutting mechanism 11, a sorting component 12, a collecting component 13, a screening component 14, and a mode switching mechanism 15. The cutting mechanism 11 is installed at the front end of the frame 10, and the sorting component 12 is installed behind the cutting mechanism 11 and fixed on the frame 10. The sorting component 12 includes a vibration sorting module 120 and a wind-powered sorting module 121. The vibration sorting module 120 is disposed at the discharge end of the cutting mechanism 11, and the wind-powered sorting module 121 is disposed at the discharge end of the vibration sorting module 120. The collecting component 13 includes a leaf collecting box 130 and a stem collecting box 131. Installed in the middle of the frame 10, the blade collection box 130 is set at the discharge end of the wind separation module 121, and the stalk collection box 131 is set below the blade collection box 130, forming a drop guide with the discharge end of the vibration separation module 120; the screening component 14 is installed inside the blade collection box 130, including a screen 140 and a fixing frame, the fixing frame is connected to the inner wall of the blade collection box 130, and the screen 140 is installed on the fixing frame; the mode switching mechanism 15 includes a switching baffle and a driving component, the switching baffle is rotatably installed between the wind separation module 121 and the blade collection box 130, and the driving component is connected to the switching baffle to drive the switching baffle to open and close.

[0028] Specifically, the cutting mechanism 11 is bolted to the front crossbeam of the frame 10, forming a rigid connection with the frame 10 to ensure cutting stability. The sorting assembly 12 is fixed to the middle crossbeam of the frame 10 by welding and bolting. The vibration sorting module 120 and the air-powered sorting module 121 are arranged sequentially along the material conveying direction. The feed end of the vibration sorting module 120 is aligned with the discharge end of the cutting mechanism 11, and the feed end of the air-powered sorting module 121 is welded to the discharge end of the vibration sorting module 120. In the collection assembly 13, the blade collection box 130 is fixed to the inner side of the middle of the frame 10 by bracket bolts, with a volume of 15L. The stalk collection box 131 has a volume of 30L, and their central axes coincide. The vertical distance between the upper edge of the stalk collection box 131 and the discharge end of the vibration sorting module 120 is 12cm, forming a stable drop guide.

[0029] Understandably, the frame 10 provides the installation foundation and support for the overall components. After the cutting mechanism 11 completes the cutting of the above-ground parts of Epimedium, the material is conveyed to the vibration sorting module 120 for pre-separation, and then enters the wind-powered sorting module 121 for fine separation. The blades are guided by wind into the blade collection box 130, and the stems are guided by drop into the stem collection box 131. The screening component 14 performs secondary impurity removal on the blades. The mode switching mechanism 15 achieves different harvesting modes by opening and closing the switching baffle. All components work together to complete the integrated operation of harvesting, sorting, and collection. This embodiment realizes the integrated integration of harvesting, vibration pre-separation, wind-powered fine separation, screening, collection, and mode switching, effectively improving the stem and leaf separation efficiency after Epimedium harvesting. All components are firmly connected, operate stably, are suitable for dense planting of Epimedium, and take into account both separation efficiency and medicinal quality.

[0030] Furthermore, the wind-powered sorting module 121 includes a fan 1210, an air guide shroud 1211, and an air speed regulator. The air guide shroud 1211 is set at the discharge end of the vibration sorting module 120. The fan 1210 is connected to the air guide shroud 1211, and the air speed regulator is electrically connected to the fan 1210. The vibration sorting module 120 includes a vibration sorting chamber 1200 and a vibration frame 1201 set in the vibration sorting chamber 1200. The vibration sorting chamber 1200 is connected to the air guide shroud 1211, and a baffle mesh plate 1212 is slidably arranged between the vibration sorting chamber 1200 and the air guide shroud 1211.

[0031] Specifically, the blower 1210 is a centrifugal blower with a rated power of 500W, an air volume range of 100-300m³ / h, and stable air pressure, which can accurately adapt to the airflow requirements for sorting Epimedium stems and leaves. In practical applications, other models can also be selected for this component, and this application embodiment does not limit this; the air guide shroud 1211 is made of transparent acrylic sheet through injection molding and is trumpet-shaped. In this embodiment, the inlet diameter is 18cm, the outlet diameter is 10cm, and the length is 25cm, which facilitates... It can observe the internal sorting situation and gather airflow; the wind speed regulating component is a speed regulating valve, which is electrically connected to the terminal of the fan 1210 through a wire; the vibration frame 1201 is a rectangular stainless steel frame. In this embodiment, the top of the vibration frame 1201 is integrally formed with a comb-shaped protrusion, and the vibration motor is fixed to the bottom center by bolts; the two sides of the baffle mesh plate 1212 are slidably connected to the connection between the vibration sorting chamber 1200 and the air guide hood 1211 through T-shaped slide rails; a handle is welded to one end of the mesh plate, which can be manually pushed and pulled to adjust the opening and closing.

[0032] Understandably, in practical applications, when the blower 1210 starts, the harvested Epimedium enters the vibrating sorting chamber 1200 under the suction of the blower 1210. Simultaneously, due to the obstruction of the baffle mesh plate 1212, mature Epimedium plants cannot enter the air guide shroud 1211. At this time, the vibrating motor drives the vibrating frame 1201 to vibrate, and the comb-like protrusions knock the stems and leaves, causing the leaves to fall off. The vibrating sorting chamber 1200 restricts the material conveying range; the baffle mesh plate 1212 obstructs... During vibration, whole plants that are not shaken off enter the air guide hood 1211. Only shaken-off leaves and small stem segments are allowed to enter the air guide hood 1211. After a specified vibration time, the baffle mesh plate 1212 is pulled open, and the Epimedium with preliminary stem-leaf separation enters the air guide hood 1211 for subsequent wind-driven stem-leaf separation. Afterward, the airflow generated by the fan 1210 converges through the air guide hood 1211, and the airflow speed is adjusted by the wind speed regulator to achieve precise separation of leaves and stem segments.

[0033] Furthermore, the cutting mechanism 11 includes a cutting blade assembly 110, a blade shaft 111, and a drive motor 112. The blade shaft 111 is rotatably mounted on the front end of the frame 10, the cutting blade assembly 110 is fixed on the blade shaft 111, and the output shaft of the drive motor 112 is rotatably connected to the blade shaft 111. The cutting blade assembly 110 is evenly distributed around the blade shaft 111.

[0034] Specifically, the cutting blade assembly 110 has an arc-shaped blunt blade structure. The drive motor 112 drives the cutter shaft 111 to rotate at a constant speed through belt transmission. The cutter shaft 111 drives the cutting blade assembly 110 to rotate synchronously. The arc-shaped blunt blade assembly cuts the above-ground parts of Epimedium evenly, avoiding damage to the stems and leaves.

[0035] Understandably, the 110 blunt blade design of the cutting blade assembly, combined with uniform rotation, can reduce damage to stems and leaves and ensure the quality of medicinal materials; at the same time, the transmission of each component is stable, the cutting efficiency is high, and it is suitable for the dense planting row spacing requirements of Epimedium.

[0036] Furthermore, the air guide shroud 1211 has a trumpet-shaped structure, with the end near the vibration sorting module 120 being the feed inlet and the end away from the vibration sorting module 120 being the air outlet. The diameter of the air outlet is smaller than the diameter of the feed inlet. The wind speed regulating component is a speed regulating valve, which is connected in series on the air inlet pipe of the blower 1210.

[0037] Specifically, the trumpet-shaped air guide shroud 1211 gathers airflow through a gradual change in diameter, increasing the air pressure at the outlet; the speed control valve is connected in series on the air inlet pipe, and controls the air outlet speed of the fan 1210 by adjusting the air inlet flow, which can adapt to the sorting needs of Epimedium stems and leaves of different maturity levels.

[0038] Understandably, the use of the horn-shaped air guide shroud 1211 results in a significant air gathering effect, stable and adjustable airflow speed, and improved airflow sorting accuracy; at the same time, the sealed connection prevents airflow leakage, ensures sorting efficiency, and adapts to different working conditions.

[0039] Furthermore, both the leaf collection box 130 and the stem collection box 131 are box structures with open tops. The leaf collection box 130 has ventilation holes 1300 on its side wall, and the stem collection box 131 has an anti-slip pad 1310 at the bottom and is connected to the frame 10 by a drawer-type sliding connection.

[0040] Specifically, the leaf collection box 130 is injection molded from high-density polyethylene material, with ventilation holes 1300 evenly opened on the side wall to facilitate airflow and avoid airflow turbulence inside the box; the stem collection box 131 is also made of high-density polyethylene material, with rubber anti-slip pads 1310 attached to the bottom to enhance placement stability. The stem collection box 131 is connected to the frame 10 on both sides by two-section drawer slides, which can achieve smooth pulling and is not easy to jam. In some embodiments, limit blocks are also provided at both ends of the slides to prevent them from falling off.

[0041] Understandably, in this design, the leaf collection box 130 discharges airflow through the ventilation hole 1300, allowing the leaves to fall and be collected smoothly; the stem collection box 131 is easily accessible via a drawer-type slide rail, and the anti-slip pad 1310 enhances the stability of the equipment during operation, preventing the box from sliding; the overall design ensures smooth airflow and prevents leaf accumulation during collection; the stem collection box 131 is easy to access and highly stable, reducing the intensity of manual operation and effectively improving work efficiency.

[0042] Furthermore, the screen 140 is inclined, and a buffer spring 141 is provided on the fixed frame. One end of the buffer spring 141 is connected to the fixed frame, and the other end abuts against the screen 140.

[0043] Specifically, in this embodiment, the tilt angle of the screen 140 is 20°. The tilt setting facilitates the sliding of small stem segments and impurities along the screen 140. The fixing frame is a rectangular stainless steel frame with a side length that matches the inner wall of the leaf collection box 130. Buffer springs 141 are set on the fixing frame at the four corners of the bottom of the screen 140. One end is welded to the fixing frame, and the other end abuts against the pressure strip at the bottom of the screen 140. The edge of the screen 140 is pressed by the stainless steel pressure strip, and the pressure strip is connected to the fixing frame by bolts to ensure that the screen 140 is firmly fixed and can shake slightly.

[0044] Understandably, after the leaves fall into the screen 140, they slide under their own weight and the slight vibration of the equipment. Small stem segments and impurities fall through the screen holes. The buffer spring 141 buffers the impact of the falling leaves and at the same time causes the screen 140 to shake slightly, improving the screening effect. In addition, the tilt setting improves the screening efficiency, and the buffer spring 141 reduces leaf damage and ensures the quality of medicinal materials.

[0045] Furthermore, the driving component of the mode switching mechanism 15 is a miniature cylinder or a stepper motor. The driving component is fixed on the frame 10, and the output end is connected to the switching baffle. When the switching baffle is fully closed, it blocks the air outlet of the air guide shroud 1211, so that the cut material falls directly into the stalk collection box 131.

[0046] Specifically, in this embodiment, the driving component of the mode switching mechanism 15 is a miniature cylinder. The cylinder is welded to the frame 10 via a bracket. The output end is connected to the rotating shaft of the switching baffle via a connecting rod. The connecting rod is made of stainless steel, and both ends are connected to the cylinder piston rod and the rotating shaft via spherical bearings to ensure flexible transmission. The driving component drives the switching baffle to rotate around the rotating shaft via the connecting rod. When it is open, the airflow drives the blades into the blade collection box 130 to achieve the stem-leaf separation mode. When it is closed, the air outlet is sealed, and the material falls directly into the stem collection box 131 after vibration to achieve the overall harvesting mode.

[0047] Furthermore, a guide plate 16 is provided between the cutting mechanism 11 and the sorting component 12. The guide plate 16 is fixed on the frame 10 and is inclined downward. One end corresponds to the discharge end of the cutting blade assembly 110, and the other end extends to the feed port of the vibration sorting module 120.

[0048] Specifically, the guide plate 16 is set at a 25° angle, which can ensure that the material slides smoothly and avoid damage caused by excessive sliding speed. The cut material falls on the guide plate 16 and slides smoothly along the inclined guide plate 16, and is accurately introduced into the feed port of the vibration sorting module 120, avoiding material scattering, ensuring the continuity of the sorting process, and further improving the overall harvesting and sorting efficiency.
