Description

Technical Field

[0001] This utility model relates to the field of oriental fruit fly trapping technology, and in particular to an oriental fruit fly trapping device. Background Technology

[0002] The oriental fruit fly, a highly destructive agricultural pest, poses a serious threat to the yield and quality of many fruit crops, such as citrus, mango, and guava. The adult flies have a strong reproductive capacity and a wide feeding range. Females lay eggs inside the fruit, and the hatched larvae feed on the fruit pulp, causing the fruit to rot and fall off, resulting in significant economic losses for fruit farmers. Therefore, effectively controlling the oriental fruit fly population is a crucial step in ensuring the healthy development of the fruit industry. Current technologies typically involve trapping oriental fruit flies using bait. Insect attractants are added to the traps, and the attractants evaporate to attract and trap the flies.

[0003] However, as the trapping process continues, the attractant will continuously evaporate, and its effective ingredients will gradually decrease, leading to a decline in its attractiveness to the oriental fruit fly. In order to maintain the normal working efficiency of the trap, fruit farmers need to manually add the attractant regularly. This process is not only tedious and time-consuming, increasing labor costs, but also makes it difficult to accurately control the amount of attractant added, as well as the frequency and timing of manual addition. This may cause the trap to be in an inefficient or ineffective working state for a period of time, thus affecting the control effect on the oriental fruit fly. Utility Model Content

[0004] The purpose of this invention is to provide a trapping device for the oriental fruit fly, which can automatically replenish the attractant, save labor, and adjust the amount of attractant added as needed to replenish the attractant quantitatively and prevent it from affecting the trapping effect of the oriental fruit fly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A trapping device for the oriental fruit fly includes an outer shell, one end of which is threaded to a detachable base, and the other end of which is provided with a liquid storage cylinder extending into it. The outer side of the outer shell has a plurality of air holes arranged at equal intervals. A U-shaped rod is slidably connected to one end of the outer side of the liquid storage cylinder near the base. A filling port is provided at one end of the liquid storage cylinder near the outer shell, and a limiting plug is slidably connected to the U-shaped rod at one end near the filling port. The U-shaped rod has a limiting slide opening at one end near the base. The liquid storage cylinder is rotatably connected to the eccentric part of the end near the base, and a first threaded rod is slidably connected to the limiting slide opening. A float is provided at the free end of the first threaded rod. A push rod is provided perpendicularly to the liquid storage cylinder at the outer end of the first threaded rod near the float. An adjusting threaded sleeve is threadedly connected to the outer end of the first threaded rod near the float. A threaded opening is provided at the end of the outer shell away from the base. Multiple limiting buckles are provided at equal intervals along the length direction of the outer side of the liquid storage cylinder near the threaded opening. A second threaded rod is threadedly connected inside the threaded opening and movably connected to each limiting buckle. The U-shaped rod is slidably connected to the second threaded rod.

[0006] By adopting the above technical solution, during use, the insect attractant is added to the storage tank for storage. The insect attractant flows into the base through the filling port. Under the buoyancy of the insect attractant, a float moves, causing the float to rotate relative to the storage tank. Simultaneously, the first threaded rod moves relative to the limiting slide. When the first threaded rod drives the adjusting threaded sleeve to contact the U-shaped rod, it causes the U-shaped rod to slide relative to the storage tank, moving the limiting plug to block the filling port, thereby stopping the addition of insect attractant to the base. By adjusting the rotation of the adjusting threaded sleeve relative to the first threaded rod, the position of the adjusting threaded sleeve can be adjusted, thereby changing the amount of insect attractant added to the base. The attractant evaporates and flows out through the pores, attracting the oriental fruit fly. The fly, drawn in, crawls into the outer shell through the pores. As the attractant evaporates, the float descends, causing the first threaded rod to rotate. This first threaded rod, via a push rod, moves the U-shaped rod, which in turn moves the limiting plug, opening the filling port and allowing the attractant to be added inside the base. Rotating the second threaded rod relative to the threaded opening causes it to move relative to the limiting buckle, which in turn moves the U-shaped rod relative to the liquid reservoir, thus blocking the filling port with the limiting plug. This facilitates the removal of the base from the outer shell and prevents the attractant from flowing out of the filling port when cleaning the oriental fruit flies and waste liquid inside the base.

[0007] A further feature of this invention is that: two opposing limiting blocks are provided on the outer side of the liquid storage cylinder near the base, and limiting slots that are slidably connected to the corresponding limiting blocks are provided on both the left and right ends of the U-shaped rod.

[0008] A further feature of this invention is that the end of the liquid storage cylinder furthest from the base is threadedly connected to a detachable end cap.

[0009] A further feature of this invention is that a knob is provided at the end of the second threaded rod away from the U-shaped rod, and limit blocks are provided at both the end of the second threaded rod near the knob and the end away from the knob.

[0010] By adopting the above technical solution, it is easy to limit the distance that the second threaded rod moves relative to the threaded opening.

[0011] A further feature of this invention is that a U-shaped hanging rod is rotatably connected to the end of the outer shell away from the base, and a hook is provided at the end of the U-shaped hanging rod away from the outer shell.

[0012] A further feature of this invention is that a transparent observation window is provided on the outer side of the base.

[0013] By adopting the above technical solution, it is easier to observe the bottom interior.

[0014] In summary, this utility model has the following beneficial effects: It can automatically replenish insect attractants and adjust the amount of insect attractant added, adding insect attractants quantitatively. Insect attractants can be stored in a storage tank and added into the base through a filling port. The insect attractant moves a float, which in turn rotates a first threaded rod relative to the storage tank. This, in turn, moves a U-shaped rod up and down through a threaded sleeve and a push rod. The U-shaped rod moves a limit plug, changing the opening and closing state of the filling port, thereby controlling the automatic addition of insect attractants into the base. By rotating the adjusting threaded sleeve, the position of the adjusting threaded sleeve can be changed, thus allowing for the quantitative addition of insect attractants into the base. Secondly, by rotating the second threaded rod relative to the threaded opening, the U-shaped rod can be moved relative to the liquid storage cylinder, which in turn causes the limiting plug to block the filling port. This makes it easier to remove the base from the outer shell and clean the fruit flies and waste liquid inside the base, thus preventing the filling liquid from flowing out of the liquid storage cylinder.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example, refer to Figure 1-4 A trapping device for the oriental fruit fly includes a housing 1. The lower end of the housing 1 is threadedly connected to a detachable base 3. The outer side of the base 3 is provided with a transparent observation window 23. The middle of the upper end of the housing 1 is provided with a liquid storage cylinder 4 that extends into it. The upper end of the liquid storage cylinder 4 is threadedly connected to an end cap 5. The upper end of the housing 1 is rotatably connected to a U-shaped hanging rod 20. The upper end of the U-shaped hanging rod 20 is provided with a hook 21 for easy hanging.

[0022] The outer shell 1 has several air holes 2 arranged at equal intervals. The lower end of the outer shell of the liquid storage cylinder 4 has two limiting blocks 7 arranged at equal intervals. The lower end of the outer shell of the liquid storage cylinder 4 is slidably connected to a U-shaped rod 8 that is slidably connected to each limiting block 7. The left and right ends of the U-shaped rod 8 are each provided with a limiting slot 9 that is slidably connected to the corresponding limiting block 7. A filling port 6 is provided on the rear side of the lower end of the liquid storage cylinder 4. A limiting plug 15 that is slidably connected to the filling port 6 is provided on the rear side of the lower end of the U-shaped rod 8. The filling port 6 is blocked by the limiting plug 15, thereby controlling the filling of insect attractant into the base 3.

[0023] A limiting slide 10 is provided at the lower end of the U-shaped rod 8. A first threaded rod 11 is rotatably connected to the left side of the lower end of the liquid storage cylinder 4 and is slidably connected to the limiting slide 10. A float 12 is provided at the end of the first threaded rod 11 away from the liquid storage cylinder 4. A push rod 13 is slidably connected to the end of the first threaded rod 11 near the liquid storage cylinder 4 and horizontally above the U-shaped rod 8. A threaded sleeve is threadedly connected to the outer side of the first threaded rod 11 below the U-shaped rod 8, which can facilitate automatic filling of insect attractant and also facilitate adjustment of the insect attractant filling amount.

[0024] The upper end of the outer shell 1 is provided with a threaded opening 16. The outer side of the liquid storage cylinder 4 is provided with multiple limit buckles 18 at equal intervals along its length near the threaded opening 16. The threaded opening 16 is internally threaded with a second threaded rod 17 that is rotatably and slidably connected to each limit buckle 18. The U-shaped rod 8 is slidably connected to the second threaded rod 17. A knob 19 is provided at the upper end of the second threaded rod 17. A limit block 22 is provided at both the upper and lower ends of the outer side of the second threaded rod 17, which can prevent the insect attractant from flowing out of the filling port 6 when the base 3 is disassembled.

[0025] Usage: In use, the insect attractant is added to the storage cylinder 4 for storage, and then the end cap 5 is installed on the storage cylinder 4 to prevent the insect attractant in the storage cylinder 4 from evaporating to the outside. The insect attractant flows into the base 3 through the filling port 6. Under the buoyancy of the insect attractant, the float 12 is pushed to move. The float 12 drives the first threaded rod 11 to rotate relative to the storage cylinder 4. At the same time, the first threaded rod 11 moves relative to the limiting slide port 10. When the first threaded rod 11 drives the adjusting threaded sleeve 14 to contact the U-shaped rod 8, it drives the U-shaped rod 8 to slide relative to the storage cylinder 4, and drives the limiting block 22 to slide relative to the limiting slot 9, thereby driving the limiting plug 15 to move and block the filling port 6, thereby stopping the addition of insect attractant to the base 3. By adjusting the rotation of the adjusting threaded sleeve 14 relative to the first threaded rod 11, the position of the adjusting threaded sleeve 14 can be adjusted, thereby changing the amount of insect attractant added to the base 3.

[0026] The base 3 is suspended by hooks 21 on the U-shaped hanging rod 20. The insect attractant evaporates and flows out through the vent 2, attracting the oriental fruit fly. The oriental fruit fly is attracted and crawls into the outer shell 1 through the vent 2. As the insect attractant evaporates, the float 12 descends, causing the first threaded rod 11 to rotate. The first threaded rod 11 drives the U-shaped rod 8 to move through the push rod 13, thereby causing the limiting plug 15 to move and opening the filling port 6. Insect attractant is added to the inside of the base 3. By turning the knob 19, the second threaded rod 17 rotates. The second threaded rod 17 rotates relative to the threaded opening 16, thereby causing the second threaded rod 17 to move relative to the limiting buckle 18, and causing the U-shaped rod 8 to move relative to the liquid storage cylinder 4, thereby causing the limiting plug 15 to block the filling port 6, making it easy to remove the base 3 from the outer shell 1 and prevent the insect attractant from flowing out of the filling port 6 when cleaning the oriental fruit flies and waste liquid inside the base 3.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
