Description

Technical Field

[0001] This utility model relates to the field of pest control technology, and in particular to a pest trap for the protection of ancient trees. Background Technology

[0002] Currently, physical trapping technology has become a core method for the integrated pest management of ancient trees due to its advantages such as being environmentally friendly and causing minimal disturbance to the growth of ancient trees. However, traditional traps have significant limitations in practical applications: the core component (the trapping core) is directly exposed to the air. In the initial stage, due to its large size and wide contact area with the air, the evaporation rate is fast and the concentration is high. As the usage time increases, the trapping core shrinks in size due to continuous evaporation, and the contact area with the air decreases accordingly, resulting in a sharp drop in the evaporation rate and unstable release concentration (excessive waste in the early stage and ineffectiveness in the later stage). This "fast at the beginning and slow at the end" release characteristic causes the trapping effect to fluctuate greatly over time, making it difficult to form a continuously effective pest trapping barrier.

[0003] For the protection of ancient trees, the shortcomings of traditional traps are even more prominent: ancient trees mostly grow in complex environments such as mountainous areas and forests, and manually replacing the trap cores is not only costly and difficult, but frequent operation may also cause additional interference to the roots and branches of the ancient trees. Therefore, there is an urgent need for a trapping device that can stably release trapping signals and reduce maintenance frequency to meet the long-term, low-interference protection needs of ancient trees. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a pest trap for the protection of ancient trees, solving the technical problem of unstable release rate of traditional slow-release cores.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pest trap for the protection of ancient trees includes a trap cage, a slow-release tube fixedly installed on the trap cage, a push plug slidably installed inside the slow-release tube, a spring installed between the push plug and the slow-release tube, a trapping core filled inside the slow-release tube, a screw cap threaded onto the bottom end of the slow-release tube, and a sealing ring fixedly installed on the push plug.

[0007] Preferred configuration: The trap is fixedly equipped with an escape-proof net, and the slow-release tube is fixedly equipped with an escape-proof disc. The bottom of the escape-proof disc has a span groove. The escape-proof net and the escape-proof disc work together to ensure that pests can only enter but cannot exit.

[0008] Preferred design: A rain cover is fixedly installed at the top of the trap, and hooks are symmetrically and rotatably installed on the rain cover. A tension spring is installed between the two hooks, so that the trap can be stably installed on the tree branch, avoiding the traditional single-hanging structure from being easily blown off by the wind.

[0009] Preferably, the top of the slow-release tube is symmetrically provided with pressure stabilizing holes, and the bottom of the slow-release tube is provided with an opening, which can balance the pressure in the upper chamber of the slow-release tube.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By utilizing the synergistic effect of the slow-release tube, push plug, spring, and trapping core, the problem of reduced contact area and unstable evaporation rate caused by volume shrinkage of traditional trapping cores is solved. The spring force continuously pushes the push plug, ensuring that the trapping core maintains a constant contact area with the opening at the bottom of the slow-release tube. The sealing ring on the push plug ensures that the upper end of the trapping core is sealed inside the slow-release tube, achieving a stable release concentration of the trapping core during its service life. Compared with traditional structures, this extends the effective trapping time, reduces replacement frequency, and lowers maintenance costs. Attached Figure Description

[0020] This application provides an insect trap for the protection of ancient trees, which effectively solves the technical problem of unstable release rate of traditional slow-release cores. Through the synergistic effect of the slow-release tube, push plug, spring and trap core, it solves the problem of reduced contact area and unstable volatilization rate caused by volume shrinkage of traditional trap cores. The spring force continuously pushes the push plug, so that the trap core always maintains a constant contact area with the opening at the bottom of the slow-release tube. The sealing ring on the push plug ensures that the upper end of the trap core is sealed in the slow-release tube, so as to achieve stable release concentration of the trap core during the service life. Compared with the traditional structure, it extends the effective trapping time, reduces the replacement frequency and reduces maintenance costs.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem of unstable release rate of traditional sustained-release cores. The overall idea is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a pest trap for the protection of ancient trees, including a trap cage 1, a slow-release tube 2 fixedly installed on the trap cage 1, a push plug 3 slidably installed inside the slow-release tube 2, a spring 4 installed between the push plug 3 and the slow-release tube 2, a trapping core 5 filled inside the slow-release tube 2, a screw cap 6 threadedly installed at the bottom end of the slow-release tube 2, and a sealing ring 7 fixedly installed on the push plug 3.

[0024] An escape-proof net 8 is fixedly installed on the trap 1, and an escape-proof disc 9 is fixedly installed on the slow-release tube 2. The bottom of the escape-proof disc 9 has a span groove 13. The escape-proof net 8 and the escape-proof disc 9 work together to ensure that pests can only enter but not exit. A rain cover 10 is fixedly installed on the top of the trap 1, and hooks 11 are symmetrically rotated on the rain cover 10.

[0025] A tension spring 12 is installed between the two hooks 11, which allows the trap cage 1 to be stably installed on the tree branch, avoiding the traditional single-hook structure from being easily blown off by the wind. The top of the slow-release tube 2 is symmetrically provided with pressure stabilizing holes 14, and the bottom of the slow-release tube 2 is provided with an opening, which can balance the pressure in the upper chamber of the slow-release tube 2.

[0026] Trapping cage 1: As the main structure of the pest trap, it provides a space for pests to be trapped. Its top is fixed with a rain cover 10, and its interior is equipped with a slow-release tube 2 and an escape-proof net 8. It is the core place where the entire trapping process takes place.

[0027] Slow-release tube 2: The inside is filled with a trapping core 5, with an opening at the bottom and a screw cap 6 installed by threads, and pressure stabilizing holes 14 symmetrically opened at the top. An escape-proof disc 9 is installed on the side. It provides a space for the trapping core 5, controls the contact between the trapping core 5 and the air, so that the trapping core 5 slowly releases the trapping odor, and at the same time works with other components to prevent pests from escaping.

[0028] Push plug 3: As the trapping core 5 evaporates and is consumed, under the elastic force of the spring 4, the push plug 3 pushes the trapping core 5 down, keeping the contact area between the trapping core 5 and the bottom opening of the slow-release tube 2 constant, thereby maintaining the stability of the concentration of the trapping odor release.

[0029] Spring 4: It pushes the pusher 3 with its own elastic force, so that the pusher 3 can continuously push the trapping core 5 down, thus solving the problem of reduced contact area and unstable evaporation rate caused by the shrinkage of the trapping core 5.

[0030] The trap core 5 is composed of silicone oil, fumed silica, D-limonene, di-tert-butyl-p-cresol, bait, and insecticide. The bait includes alcohol acetate (for codling moth and peach fruit moth) and hexenal (for apple aphid), etc. It is solid and comes into contact with air through the bottom opening of the slow-release tube 2, releasing an attractive odor to pests and attracting them into the trap cage 1. At the same time, the insecticide it contains can poison and kill the pests that enter the trap cage 1 and consume it.

[0031] Screw cap 6: Used to open or close the inlet of the slow-release tube 2, facilitating the installation and replacement of the trap core 5. After installation, it seals the inlet of the slow-release tube 2 to ensure that the trap core 5 evaporates stably inside the slow-release tube 2.

[0032] Sealing ring 7: Ensures the seal between the push plug 3 and the slow-release tube 2, so that the upper part of the trapping core 5 is sealed inside the slow-release tube 2 and does not come into contact with the air. Only the bottom comes into contact with the air through the bottom opening of the slow-release tube 2 to volatilize, thus maintaining the stability of the release of the trapping odor.

[0033] Escape-proof net 8: guides pests into trap cage 1, while preventing pests from escaping from the side of trap cage 1, so that pests can only enter the trap cage 1 along the escape-proof net 8.

[0034] Escape-proof disc 9: When pests climb up along the slow-release tube 2, the escape-proof disc 9 acts as a barrier. The span groove 13 creates a span between the inner and outer edges of the escape-proof disc 9, further preventing pests from climbing out and trapping them inside the trap cage 1.

[0035] Rain cover 10: Fixed to the top of the trap cage 1, it shelters the trap cage 1 and its internal components from wind and rain, prevents rainwater from entering the trap cage 1 and affecting the volatilization of the trap core 5 and the normal operation of the trap, and extends the service life of the trap core 5.

[0036] Hook 11: After being pulled and rotated to unfold, it hangs on the tree branch. Then, under the elastic force of the tension spring 12, it rotates inward to reset and locks the tree branch from both sides, thus fixing the trap on the tree branch.

[0037] Tension spring 12: provides an inward rotational elastic force for hook 11, so that hook 11 can be firmly locked onto the branch after being hooked, ensuring that the trap is stably suspended on the branch;

[0038] Span groove 13: Makes the inner and outer edges of the escape-proof disc 9 form a span, increasing the difficulty for pests to climb out and effectively preventing pests from climbing out of the trap 1 along the slow-release tube 2.

[0039] Pressure stabilizing hole 14: keeps the upper chamber of the slow-release tube 2 in contact with the outside air to balance the internal and external air pressure, which helps the push plug 3 to slide.

[0040] Working principle:

[0041] First, during installation, unscrew the cap 6, then insert the trapping core 5 into the slow-release tube 2 from the bottom. Once the trapping core 5 is inserted, the push plug 3 will push the spring 4 to slide, compressing the spring 4. Then tighten the cap 6 to block the entrance of the slow-release tube 2. Next, pull and rotate the two hooks 11 to unfold them, stretching the tension spring 12. Hang the two hooks 11 on the tree branch and then release them. At this time, the two hooks 11 will rotate inward and reset under the elastic force of the tension spring 12, so that the two hooks 11 can be locked onto the tree branch from both sides to complete the installation.

[0042] The second step is to use the trap 5 after installation. The bottom of the trap 5 is in contact with the air through the opening at the bottom of the slow-release tube 2, while the rest of the trap 5 is located inside the slow-release tube 2 and is not in direct contact with the air. The part of the trap 5 that is in contact with the air will slowly evaporate from the opening at the bottom of the slow-release tube 2, releasing the odor that attracts pests. As time goes by, the bottom of the trap 5 will continue to evaporate and disappear. At this time, the push plug 3 will push the trap 5 down under the elastic force of the spring 4, so that the area of ​​the lower part of the trap 5 in contact with the air is consistent, and the concentration of the odor released by the trap 5 during use is maintained within a stable range.

[0043] Third, after being attracted, the pests will enter along the escape-proof net 8. Because the area where the trap core 5 releases its scent is located at the bottom of the slow-release tube 2, the pests will continue to go deeper along the escape-proof net 8, preventing them from only staying at the entrance. When the pests enter the trap cage 1, if they eat the trap core 5, the insecticide in the trap core 5 will kill them. If the pests climb up along the slow-release tube 2, they will be blocked by the escape-proof disc 9. The span groove 13 of the escape-proof disc 9 creates a span between the inner edge and the outer edge of the escape-proof disc 9 to prevent the pests from climbing out, thus trapping the pests inside the trap cage 1.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
