Description
Technical Field
[0001] This utility model relates to the field of insect trapping technology, and in particular to an insect trapping device. Background Technology
[0002] Healthy crop growth is a crucial cornerstone of global food security. Pests are a common problem during crop cultivation, and without proper control, they can significantly impact yields. Many common crop pests exhibit significant differences in their biological characteristics. For example, targeting phototactic pests requires specific wavelengths of light for effective trapping, while pests that rely on chemical pheromones for location require pheromone-based odor trapping. Pest monitoring also faces these challenges. Traditional traps often have a single function, necessitating the deployment of multiple specialized traps for each pest. This results in a large number of traps scattered across the field, making centralized management difficult and ultimately affecting overall pest control efficiency and the precision of field management. Furthermore, light-based traps have limited illumination range, restricting the capture area and reducing trapping efficiency. Utility Model Content

[0017] In one embodiment, the bottom of the shell body has two oppositely arranged connecting guide rails, and the two ends of the limiting plate are respectively embedded in the two connecting guide rails.

[0027] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0028] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] like Figures 1 to 3 As shown, this utility model provides a pest trapping device, which includes a support column 1, a trapping lamp assembly 2, and a trapping bucket assembly 3.
[0035] Support column 1 forms a support structure, and the trapping lamp assembly 2 is detachably mounted on support column 1. The trapping lamp assembly 2 includes a trapping lamp 21, an electric grid 22, and a protective shell 23. The trapping lamp 21 is configured to emit trapping light waves. The electric grid 22 surrounds the trapping lamp 21. The protective shell 23 includes a shell body 231, a protective net 232, and multiple light-guiding trapping plates 233. The shell body 231 surrounds the electric grid 22 and has a light-transmitting window 2311. The protective net 232 is detachably connected to the shell body 231 and blocks the light-transmitting window 2311. The protective net 232 blocks the electric grid 22, but the mesh on the surface of the protective net 232 allows pests to pass through, reducing the risk of contact between people or poultry and the electric grid 22, thus increasing the safety of the trapping lamp assembly 2 during use. Furthermore, the protective net 232 does not obstruct the trapping light waves, and can be replaced after prolonged use to ensure its permeability. Multiple light-guiding trapping plates 233 are spaced apart along the outer periphery of the shell body 231. One end of each light-guiding trapping plate 233 is connected to the shell body 231, and the other end extends outward toward the shell body 231. At least a portion of the surface of each light-guiding trapping plate 233 is provided with adhesive elements 2331. The light-guiding trapping plates 233 are configured to reflect trapping light waves. The trapping barrel assembly 3 is mounted on the support column 1. The trapping barrel assembly 3 includes a trapping barrel 31 and a trapping agent block disposed within the trapping barrel 31. The trapping agent block is configured to slowly release trapping pheromones. The trapping barrel 31 has ventilation holes.
[0036] The pest trapping device provided in this embodiment uses a trapping lamp 21 to send trapping light waves to accurately attract phototactic pests. When the pests touch the electric grid 22, they are instantly killed. The trapping agent block in the trapping barrel 31 releases trapping pheromones to trap pests that rely on chemical pheromones for location, thus luring the pests closer to be killed by the electric grid 22. One end of the light-guiding trap plate 233 extends outward toward the outer side of the shell body 231. The light-guiding trap plate 233 reflects the trapping light waves, making the propagation range of the trapping light waves farther, and the trapping lamp 21 forms a larger illumination area, which is conducive to improving the trapping efficiency. Moreover, the adhesive trapping element 2331 set on the surface of the light-guiding trap plate 233 captures pests by adhesion. The pest trapping device integrates multiple methods such as spectral trapping, pheromone trapping and physical killing, realizing multi-source composite trapping and killing. It can effectively kill a variety of common tobacco pests with different biological characteristics, which is convenient for centralized management, reduces the number of field equipment, and improves the overall pest control efficiency and the level of precision in field management.
[0037] The pest trapping device in this embodiment can be used not only for pest control in the planting process of tobacco, grain crops, and medicinal crops, but also for insect pest monitoring and pest forecasting.
[0038] The trapping light assembly 2 is detachably mounted on the support column 1. If any of the trapping light 21, the electric grid 22, or the protective shell 23 malfunctions, the trapping light assembly 2 can be disassembled for repair or replacement.
[0039] In one embodiment, the trapping lamp 21 can emit ultraviolet and green light. By employing a dual-band combination of ultraviolet and green light, it can precisely attract phototactic pests such as the beet armyworm and cotton bollworm, thus attracting a wider range of pests. The specific composition of the trapping block can be selected according to common tobacco pests, and this embodiment does not impose specific limitations. For example, the trapping block can diffuse sex pheromones targeting tobacco aphids and tobacco mirid bugs. The protective net 232 is made of plastic and has an insulating effect.
[0040] The shell body 231 has multiple edges 2312, each edge 2312 corresponding to a multiple light-guiding trapping plate 233. Each edge 2312 has a light-transmitting window 2311 on both sides, and the two light-transmitting windows 2311 are symmetrically arranged relative to the light-guiding trapping plate 233. For example, Figure 3 The middle shell body 231 is a rectangular frame with four edges 2312, and four light guide trapping plates 233 are set accordingly. The four light guide trapping plates 233 extend outward in a radiating manner, greatly increasing the trapping range.
[0041] In one embodiment, adhesive elements 2331 are provided on both sides of the light guide trapping plate 233 to expand the capture area. The adhesive elements 2331 are detachable and can be replaced when the capture efficiency decreases.
[0042] The trapping lamp assembly 2 is detachably connected to the trapping bucket assembly 3, and is positioned above the trapping bucket assembly 3. The pest trapping device also includes a rainproof eaves 4, which covers the top of the trapping lamp assembly 2. The rainproof eaves 4 includes multiple inclined water-guiding baffles 41, and the projection of the rainproof eaves 4 along its height direction at least covers the shell body 231. In one embodiment, the maximum dimension of the rainproof eaves 4 is larger than the circumferential dimension of the shell body 231, and the ends of the water-guiding baffles 41 extend to the outside of the shell body 231, providing better protection. Rainwater flows away quickly through the inclined water-guiding baffles 41 of the rainproof eaves 4, reducing rainwater accumulation and improving the safety of the lower structural components during use.
[0043] The pest trapping device also includes an electrical box assembly 5, which is located between the rainproof eaves 4 and the trapping lamp assembly 2. The electrical box assembly 5 includes an electrical box housing 51 and an electrical control module 52 disposed within the housing 51. The electrical control module 52 is electrically connected to the trapping lamp 21 and the power grid 22. The electrical control module 52 enables intelligent regulation, controlling the switching of the trapping lamp 21 and parameters such as the voltage of the power grid 22. The electrical control module 52 also provides power to the trapping lamp 21 and the power grid 22. The specific structure and control principle of the electrical control module 52 can be set with reference to existing technologies, and will not be elaborated upon in this embodiment.
[0044] The pest trapping device also includes a solar panel 6, which comprises a battery and a solar panel detachably mounted on a support column 1. The solar panel provides power to the battery, which is electrically connected to an electronic control module 52. The solar panel is tilted at the top of the support column 1. The solar panel provides power to the electronic control module 52 via the battery. In another embodiment, the electronic control module 52 has a built-in power storage device or is connected to the mains power grid to ensure power supply during cloudy or rainy weather and provide power stability. The specific structure and power supply principle of the solar panel 6 can be set with reference to existing technologies, and will not be described in detail in this embodiment.
[0045] The electrical control module 52 generates heat during operation, and heat dissipation holes 511 are provided on the side of the electrical box housing 51. Multiple heat dissipation holes 511 are provided, all located within the shielding area of the rainproof eaves 4. During heat dissipation, the rainproof eaves 4 reduce the entry of rainwater and prevent direct sunlight.
[0046] In one embodiment, the trapping bucket 31 includes a bucket body 311 and a limiting plate 312 detachably connected to the top of the bucket body 311. The limiting plate 312 has a through hole 3121 and is located below the trapping lamp 21. The trapping bucket 31 has an accommodating space. Pests killed by the trapping lamp 21 and the electric grid 22 fall into the trapping bucket 31 through the through hole 3121. The detachable connection between the limiting plate 312 and the bucket body 311 facilitates the regular cleaning of pest remains and the replacement of the bait blocks.
[0047] In one embodiment, one of the limiting plate 312 and the shell body 231 is provided with a connecting guide rail 2313, and the other is movably embedded in the connecting guide rail 2313. The quick installation between the trapping barrel 31 and the protective shell 23 is achieved through the movable connection of the connecting guide rail 2313.
[0048] Specifically, the bottom of the shell body 231 has two opposing connecting rails 2313. The two ends of the limiting plate 312 are respectively embedded in the two connecting rails 2313. One end of each connecting rail 2313 is open along its length, and the other end has a sealing limiting member used to abut and limit the limiting plate 312. The limiting plate 312 is inserted into the connecting rail 2313 from the open end and slides along the length of the connecting rail 2313 until it abuts the sealing limiting member. At this time, the trapping bucket 31 is located directly below the trapping lamp 21, facilitating the collection of killed pests through the through hole 3121. After the limiting plate 312 is pulled out from the connecting rail 2313, the connection between the bucket body 311 and the limiting plate 312 is disassembled, allowing for quick replacement of the trapping agent block inside the trapping bucket 31 and cleaning of the insects inside.
[0049] The electric field 22 includes an inner net 221 and an outer net 222 arranged sequentially from the center of the trapping lamp 21 outwards. The voltage of the inner net 221 is higher than that of the outer net 222. Through the stepped electric field arrangement, the low-voltage outer net 222 attracts large pests, while the high-voltage inner net 221 achieves instantaneous killing, resulting in higher killing efficiency.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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.
