Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pest control, and in particular to a fall armyworm adult trapping device. Background Technology
[0002] The fall armyworm, also known as the autumn armyworm or fall cutworm, is a species of moth belonging to the genus *Noctuidae* in the family Noctuidae. The adult has a wingspan of 32 to 40 mm. Its forewings are variable in color; females are gray to grayish-brown, while males are dark brown with black spots and light-colored markings. The fall armyworm causes serious damage to crops and grasslands. A Chinese utility model patent with publication number CN222485868U discloses a trapping device for the fall armyworm. This device includes a first trapping mechanism and a second trapping mechanism that slides onto the top of the first trapping mechanism. The first trapping mechanism includes a hollow first cylinder with an inlet on its side. A one-way insect-entry component is installed at the inlet. The interior of the first cylinder... The device features a tray containing an attractant; a second trapping mechanism includes a hollow second cylinder with a trapping lamp at the top and an electric insect net at the bottom. When a fall armyworm is attracted by the attractant and enters the first cylinder unidirectionally, it is then drawn to the vicinity of the second cylinder by the trapping lamp and touches the electric insect net, where it is electrocuted. This not only effectively improves the trapping effect on fall armyworms, but also allows the second cylinder to be stored inside the first cylinder via a sliding fitting, solving the problem of traditional trapping devices lacking portability due to fixed installation. It is movable and easy to store, making it convenient and practical.
[0003] However, after the fall armyworm is attracted by the bait, the above-mentioned trapping device can only complete the trapping by waiting for the fall armyworm to actively enter the trap on its own. This results in poor initiative of the trapping device and a low success rate of trapping. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fall armyworm adult trapping device that can actively suck fall armyworms into the trapping box, with high initiative in trapping and improved trapping success rate.
[0005] This utility model discloses a fall armyworm adult trapping device, comprising a trapping box, a mounting base, and a trapping mechanism. The trapping box has a trapping chamber inside, and an inlet communicating with the trapping chamber is located on the upper surface of the trapping box. The mounting base is installed in the trapping chamber of the trapping box, and the trapping mechanism is detachably mounted on the mounting base. The device also includes a funnel, a duct, a fan, and a solar panel. The funnel is installed at the inlet of the trapping box, with its lower opening extending into the inlet and its upper part extending outwards from the outside of the trapping box. The duct... Installed on the trap box, the lower end of the duct extends into the funnel and aligns with the bait overflow hole of the trap box. A fan is installed inside the duct, and a solar panel is installed at the top of the duct, powering the fan. During operation, the trap box is placed on a bracket or buried in the ground with the upper edge of the funnel flush with the ground. The solar panel powers the fan, turning it on. The fan expels air upwards from inside the duct, causing the lower end of the duct to rapidly draw air from the funnel and the trap chamber of the trap box. This creates an airflow intake zone around the funnel. Simultaneously, the attractant gas diffused from the trapping box is drawn into the duct along with the airflow and discharged above the duct. This causes the attractant to spread more rapidly with the exhaust airflow from the fan, expanding the trapping area. Fall armyworms within the trapping area are attracted to the vicinity of the trapping box. When a flying fall armyworm approaches the funnel and enters the airflow intake zone, it is sucked into the funnel and falls through the lower opening of the funnel into the trapping chamber of the trapping box. When a crawling fall armyworm enters the airflow intake zone... The fall armyworm is drawn into the funnel by the airflow, causing it to slide down the inclined funnel and fall into the trapping chamber of the trapping box through the lower opening. This traps both flying and crawling fall armyworms. Because the lower opening of the funnel extends into the insect inlet of the trapping box, the lower part of the funnel intercepts the trapped fall armyworm, preventing it from crawling or flying out. Compared with existing technologies, this method can actively draw the fall armyworm into the trapping box, resulting in a higher degree of active trapping and a higher success rate.
[0006] Preferably, it also includes an upper cover plate, which is installed on the outer side of the upper end of the duct pipe and is located above the funnel. The upper cover plate can reduce the entry of rainwater and dust into the funnel and the trapping chamber of the trapping box, and limit the airflow inhalation area between the upper cover plate and the funnel, thereby improving the inhalation effect of the inhaled airflow on the fall armyworm.
[0007] Preferably, it also includes multiple trapping lights, which are installed on the upper cover plate; the solar panel supplies power to the multiple trapping lights, causing them to emit light and trap fall armyworm, thereby improving the trapping efficiency.
[0008] Preferably, it also includes a handle, which is installed on the culvert pipe and the culvert pipe is mounted on the trap box in a height adjustable manner; the installation of the handle makes it convenient to lift and press the culvert pipe, and also makes it convenient to move and transport the trap box by holding the handle.
[0009] Preferably, it also includes air guide blocks. The upper crossbeam of the handle is located in the middle above the upper end of the duct pipe. Air guide blocks are provided on both sides of the upper crossbeam of the handle. The two air guide blocks guide the airflow discharged by the fan to both sides. By dividing and guiding the airflow through the two air guide blocks, the diffusion range of the inducer is improved.
[0010] Preferably, the device also includes a column, a sliding sleeve, and a hook rod. The column is vertically installed in the trapping chamber of the trapping box. The sliding sleeve is installed on the lower side wall of the duct pipe and is slidably fitted onto the column. The lower end of the hook rod is elastically rotatably mounted on the sliding sleeve, and a hook is provided on the upper part of the hook rod for hooking the top of the column. The duct pipe is slidably fitted onto the column through the sliding sleeve, allowing the duct pipe to rise and fall. When the duct pipe falls, trapping stops and the upper cover plate covers the funnel. When the duct pipe rises, trapping begins, and the hook of the hook rod is hooked onto the top of the column, thus locking the duct pipe.
[0011] Preferably, the device also includes an electric shock net and a high-voltage module. The electric shock net is installed in the trapping chamber of the trapping box, located below the lower opening of the funnel. The high-voltage module is installed in the trapping chamber of the trapping box and is electrically connected to the electric shock net and the solar panel. The solar panel supplies power to the high-voltage module, which in turn supplies power to the electric shock net, causing the electric shock net to shock the fall armyworms that fall into the trapping chamber of the trapping box, thereby increasing the success rate of trapping fall armyworms.
[0012] Compared with the prior art, the beneficial effects of this utility model are: it can actively suck the fall armyworm into the trap box, with high initiative in trapping and improved trapping success rate. Attached Figure Description

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0016] like Figures 1 to 5 As shown, a fall armyworm adult trapping device includes a trapping box 1, a mounting base 2, and a trapping mechanism 3. The trapping box 1 has a trapping chamber inside, and an inlet communicating with the trapping chamber is located on the upper surface of the trapping box 1. The mounting base 2 is installed in the trapping chamber of the trapping box 1, and the trapping mechanism 3 is detachably installed on the mounting base 2. The device also includes a funnel 4, a duct 5, a fan 6, and a solar panel 7. The funnel 4 is installed on the inlet of the trapping box 1, with its lower opening extending into the inlet and its upper part extending outwards from the outside of the trapping box 1. The duct 5 is installed on the trapping box 1, with its lower end extending into the funnel 4 and facing the attractant overflow hole of the trapping mechanism 3. The fan 6 is installed in the duct 5, and the solar panel 7 is installed on the upper part of the duct 5, providing power to the fan 6. The device also includes a top cover 8. The upper cover plate 8 is located above the funnel 4 and is installed on the outer side of the upper end of the duct pipe 5. It also includes multiple trapping lights 9, which are installed on the upper cover plate 8. It also includes a handle 13, which is installed on the duct pipe 5. The duct pipe 5 is mounted on the trapping box 1 in a height-adjustable manner. It also includes air guide blocks 14. The upper crossbeam of the handle 13 is located in the middle above the upper end of the duct pipe 5. Air guide blocks 14 are provided on both sides of the upper crossbeam of the handle 13. The two air guide blocks 14 guide the airflow discharged by the fan 6 to both sides. It also includes a column 10, a sliding sleeve 11, and a hook rod 12. The column 10 is vertically installed in the trapping chamber of the trapping box 1. The sliding sleeve 11 is installed on the lower side wall of the duct pipe 5 and is slidably fitted on the column 10. The lower end of the hook rod 12 is elastically rotatably installed on the sliding sleeve 11. The upper part of the hook rod 12 is provided with a hook for hanging the top of the column 10.
[0017] During operation, the handle 13 facilitates lifting and pressing of the duct pipe 5, and also allows for easy movement and transport of the trapping box 1. The trapping box 1 is placed using a support or buried in the ground with the upper edge of the funnel 4 flush with the ground. The duct pipe 5 is slidably fitted onto the column 10 via a sliding sleeve 11, allowing the duct pipe 5 to rise and fall. Trapping stops after the duct pipe 5 descends, and the upper cover 8 covers the funnel 4. The upper cover 8 reduces the entry of rainwater and dust into the funnel 4 and the trapping chamber of the trapping box 1, and confines the airflow intake area within the upper cover 8 and the funnel. Between the funnels 4 and 5, the intake airflow is enhanced to improve the absorption effect on the fall armyworm. Trapping begins after the culvert 5 is raised, and the hook of the hook rod 12 is attached to the top of the column 10, locking the culvert 5. The solar panel 7 powers multiple trapping lights 9, causing them to emit light and trap the fall armyworm. The solar panel 7 also powers the fan 6, turning it on. The fan 6 expels air upwards from inside the culvert 5, causing the lower end of the culvert 5 to rapidly draw in air from the funnel 4 and the trapping chamber of the trapping box 1, creating an airflow around the funnel 4. In the airflow intake zone, the attractant gas diffused from the trapping box 3 is drawn into the duct 5 along with the airflow and discharged above the duct 5. Two air guide blocks 14 divide and guide the airflow, causing the attractant to diffuse more rapidly with the exhaust airflow of the fan 6, expanding the trapping range. Fall armyworms within the trapping range are attracted to the vicinity of the trapping box 1. When a flying fall armyworm approaches the funnel 4 and enters the airflow intake zone, it is drawn into the funnel 4 and falls into the trapping chamber of the trapping box 1 through the lower opening of the funnel 4. When a crawling fall armyworm enters the airflow... When the fall armyworm enters the suction area, it is drawn into the funnel 4 by the airflow, causing it to slide down the inclined funnel 4 and fall into the trapping chamber of the trapping box 1 through the lower opening of the funnel 4. This achieves the trapping of both flying and crawling fall armyworms. Since the lower opening of the funnel 4 extends into the insect inlet of the trapping box 1, the lower part of the funnel 4 intercepts the trapped fall armyworm, preventing it from crawling or flying out. Compared with existing technologies, this method can actively draw the fall armyworm into the trapping box 1, resulting in higher trapping initiative and a higher success rate. Example 2
[0018] like Figure 1 , Figure 2 and Figure 6 As shown, based on Embodiment 1, it also includes an electric shock net 15 and a high-voltage module 16. The electric shock net 15 is installed in the trapping chamber of the trapping box 1, located below the lower opening of the funnel 4. The high-voltage module 16 is installed in the trapping chamber of the trapping box 1, and is electrically connected to the electric shock net 15 and the solar panel 7. The solar panel 7 supplies power to the high-voltage module 16, and the high-voltage module 16 supplies power to the electric shock net 15, so that the electric shock net 15 shocks the fall armyworms that fall into the trapping chamber of the trapping box 1, thereby improving the success rate of trapping fall armyworms.
[0019] like Figures 1 to 6 As shown, this utility model discloses a fall armyworm adult trapping device. During operation, the trapping box 1 is first positioned by holding the handle 13, and the duct pipe 5 is raised, causing the upper cover 8 to open the funnel 4. Then, the solar panel 7 supplies power to multiple trapping lights 9, causing them to illuminate and attract the fall armyworm. The solar panel 7 also supplies power to the fan 6, turning it on. The fan 6 expels air upwards from inside the duct pipe 5, causing the lower end of the duct pipe 5 to rapidly draw in air from the funnel 4 and the trapping chamber of the trapping box 1, creating an airflow intake zone around the funnel 4. Simultaneously, the attractant gas diffused from the trapping box 3 is drawn into the duct pipe 5 along with the airflow and discharged above the duct pipe 5. The air guide block 14 directs the airflow of the attractant to both sides, allowing the attractant to spread faster with the exhaust airflow of the fan 6 and expand the trapping range. Then, the fall armyworms within the trapping range are attracted to the vicinity of the trapping box 1. When the flying fall armyworms approach the funnel 4 and enter the airflow inhalation area, they are sucked into the funnel 4 and fall into the trapping chamber of the trapping box 1 through the lower opening of the funnel 4. When the crawling fall armyworms enter the airflow inhalation area, they are sucked into the funnel 4 by the airflow, causing the fall armyworms to slide down the inclined funnel 4 and fall into the trapping chamber of the trapping box 1 through the lower opening of the funnel 4. Finally, the electric net 15 electrocutes and kills the fall armyworms that have fallen into the trapping chamber of the trapping box 1.
[0020] The main functions achieved by this utility model are: 1. It can actively draw fall armyworms into trap box 1, demonstrating high initiative in trapping and increasing the success rate of trapping; 2. Multiple light-emitting lamps are used to attract and trap fall armyworms, improving trapping efficiency; 3. The electric shock net 15 can shock the fall armyworm that falls into the trap chamber of the trap box 1, thereby increasing the success rate of trapping fall armyworm.
[0021] The fall armyworm adult trapping device of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired beneficial effect can be implemented. The trapping box 1, mounting base 2, trapping machine box 3, funnel 4, duct pipe 5, fan 6, solar panel 7, trapping light 9, column 10, sliding sleeve 11, hook rod 12, handle 13, electric shock net 15, and high voltage module 16 of this utility model are commercially available.
