Description

Technical Field

[0001] This utility model relates to the field of insect trapping, and more specifically, to a portable device for trapping or killing insects, and even more specifically, to a partially buried insect trap with a simple structure. Background Technology

[0002] In the tobacco industry, the health of tobacco plant leaves plays a crucial role in the quality of the final tobacco product. Tobacco leaves, as the key part of the tobacco plant for photosynthesis, synthesis of organic matter, and the embodiment of its economic value, are highly susceptible to various insect infestations. Insect damage to tobacco leaves not only directly reduces leaf area, affecting the plant's photosynthetic efficiency, especially in seedlings, and even severely reducing tobacco yield, but the wounds caused by insects can also become entry points for pathogens, leading to various diseases and further damaging the quality of the tobacco. To ensure tobacco quality, insect traps are a scientific and practical method commonly used in tobacco cultivation management for monitoring and controlling pests. Insect traps play a key role in tobacco fields as an important pest monitoring and control tool. These traps are generally designed as small devices, distributed evenly throughout the tobacco field. Through specific bait or trapping mechanisms, they attract and capture surrounding insects, helping growers to understand the types, numbers, and activity patterns of insects in the tobacco field, providing a strong basis for developing scientific and reasonable pest control strategies.

[0003] The inventors discovered that, in essence, insect traps need to attract and kill insects. However, due to weather changes, water needs to be added to the insect traps during the dry season, otherwise the dispersal effect of the trapping medium is poor. Moreover, most insects are attracted to water. Furthermore, without water to restrain them, there is no adhesion for the insects, allowing them to escape easily. During the frequent rainy season, the trapping medium is often irrigated and overflowed by rainwater, causing the insect-prevention to fail. Utility Model Content

[0004] To address the problems of reduced trapping efficiency and easy escape of insects due to water shortage during the dry season, as well as the failure of the trapping medium due to rainwater erosion during the rainy season, this application provides a partially buried insect trap. The first aspect of this application provides a partially buried insect trap, including an inner container comprising a first shell and a cover, wherein the interior of the first shell is a first receiving cavity for placing a trapping medium; and an outer container comprising a second shell, wherein the interior of the second shell is a second receiving cavity; wherein at least a portion of the first shell can be accommodated within the second receiving cavity, and the outer wall of the accommodated portion of the first shell is spaced apart from the inner wall of the second receiving cavity; a plurality of first radial through holes of a first height are provided on the outer peripheral wall of the accommodated portion of the first shell, and a plurality of second radial through holes of a second height are provided on the outer peripheral wall of the second shell, wherein the first radial through holes are relatively higher than the second radial through holes.

[0005] In a further feasible embodiment of this application, a trapping medium net is provided on the bottom wall of the first shell.

[0006] In a further feasible embodiment of this application, the insect trap also includes a base, which includes a first part and a second part. The first part contacts the bottom of the trench into which the insect trap is buried, and the second part creates a gap between the bottom wall of the second housing and the bottom of the trench.

[0007] In a further feasible embodiment of this application, the inner container includes a fence, and the cover is connected to the open end of the first housing through the fence, so that a gap is left between the cover and the opening of the first housing.

[0008] In a further feasible embodiment of this application, the cover includes a central portion and an edge portion, the edge portion protruding radially from the first housing, and a plurality of water guiding holes are provided at the edge portion; the diameter of the second housing gradually increases in the direction away from the cover to form a water guiding surface on the outer wall of the second housing; rainwater passing through the water guiding holes falls onto the water guiding surface.

[0009] In a further feasible embodiment of this application, the side of the cover facing away from the first shell adopts a curved or inclined surface from the center outward.

[0010] In a further feasible embodiment of this application, the first housing includes a mounting portion and a body portion along the axial direction, with the mounting portion protruding radially relative to the body portion; when the inner container is assembled inside the outer container, a portion of the mounting portion abuts against the end of the second housing.

[0011] In a further feasible embodiment of this application, the mounting part is provided with a plurality of holding openings, which are notches that are recessed inward relative to the outside of the mounting part.

[0012] In the optional embodiments of this application, the first height is 1 / 2 to 2 / 3 of the overall height of the first shell; the second height is 1 / 3 to 1 / 2 of the overall height of the second shell.

[0013] In a further embodiment of this application, the bottom wall of the first housing and the bottom wall of the second housing are spaced apart. Compared with existing technologies, the partially buried insect trap provided by this utility model has the following advantages: Through the above design, the first shell has water storage capacity. The first shell forms a water level linkage system with the second shell through the first radial through hole. When rainwater enters the first receiving cavity and overflows the through hole, the excess water is discharged through the through hole, forming a dynamic water storage layer. The water stored in the second shell can reduce the evaporation rate of the first shell. The double-layer structure forms a water interlayer, which inhibits the heat conduction of the soil and the photolysis reaction of the trap. Thus, rainwater can be stored during rainy weather to maintain the humidity of the trapping medium. On sunny days, it can be used to enhance the diffusion efficiency of volatile traps. The water level in the water storage layer in the first receiving cavity rises to form a "wet trap". Insects slide into the mixed medium in the first receiving cavity and are killed. This method reduces the frequency of human intervention and maintenance pressure compared with traditional traps.

[0014] In summary, this application provides a simple, partially buried insect trap. The first shell and the second shell form a "water level threshold control" through a first radial through-hole. When there is no rainfall, the water storage layer maintains humidity through artificial water replenishment or natural dew, ensuring that the trapping medium continues to function. When it rains, after the water level exceeds the through-hole, the excess water is discharged through the second radial through-hole, preventing the medium from overflowing from the opening of the inner container.

[0023] Please refer to Figures 1 to 5 This application provides a partially buried insect trap 100, including an inner container 10 and an outer container 20. The inner container 10 includes a first shell 11 and a cover 12. The first shell 11 has a first receiving cavity A inside, which is used to place a trapping medium (such as sex pheromones, food bait, etc.). The outer container 20 includes a second shell 21, which has a second receiving cavity B inside. At least a portion of the first shell 11 can be accommodated in the second receiving cavity B. The outer wall of the accommodated portion of the first shell 11 is spaced apart from the inner wall of the second receiving cavity B. The outer peripheral wall of the accommodated portion of the first shell 11 has a plurality of first radial through holes a of a first height, and the outer peripheral wall of the second shell 21 has a plurality of second radial through holes b of a second height. The first radial through holes a are relatively higher than the second radial through holes b.

[0024] Understandably, when in use, the outer container 20 of the insect trap is partially buried underground for fixation and protection, while also making contact with the surrounding soil. A portion of the inner container 10 is exposed above ground, serving as an entrance for insects to lure them into the first containment cavity A. When rainwater is used for irrigation, it first enters the first containment cavity A of the inner container 10. As the water level rises, the water overflows the first radial through-hole a on the inner container 10 and flows from the first containment cavity A into the second containment cavity B of the outer container 20. If the rainfall continues to increase, causing the water level in the second containment cavity B to also rise, the water will continue to flow out through the second radial through-hole b on the outer container 20 and be absorbed into the surrounding soil. The height of the first radial through hole a is higher than that of the second radial through hole b. This design ensures that rainwater needs to reach a certain height after flowing into the second receiving cavity B before it can flow out through the second radial through hole b. The height difference provides the inner container 10 with a certain water storage capacity, while preventing water in the soil from flowing back into the inner container 10 directly through the second radial through hole b. The trapping medium is placed at the bottom of the first shell 11 of the inner container 10. Due to its structure and the overall buried design, the trapping medium cannot overflow through the exposed part of the inner container 10, and is thus effectively retained inside the trap.

[0025] In the optional embodiments of this application, the first height is 1 / 2 to 2 / 3 of the overall height of the first housing 11; the second height is 1 / 3 to 1 / 2 of the overall height of the second housing 21; simply put, when the first height is taken as a reference to the first housing 11, it is located at 1 / 2 to 2 / 3 of the overall height of the first housing 11, and the second height is similar.

[0026] In a further embodiment of this application, the bottom wall of the first housing 11 and the bottom wall of the second housing 21 are spaced apart to form a channel at the bottom between the two housings.

[0027] In some alternative solutions, a trapping medium net c can be provided at the bottom of the first housing 11, specifically at the bottom of the first receiving cavity A, to improve the stability of the trapping medium. The trapping medium net c can act as a fine sieve. When the trapping medium flows inside the first housing 11 or is disturbed by the outside, the mesh structure of the net can block larger components such as particles and lumps in the medium, preventing them from moving or being lost at will, thereby maintaining the overall relative stability of the medium and reducing the disorderly diffusion of the medium at the bottom of the housing.

[0028] More importantly, the above design enables the first shell 11 to store water. The first shell 11 forms a water level linkage system with the second shell 21 through the first radial through hole a. When rainwater enters the first receiving cavity A and overflows through hole a, excess water is discharged through the outer through hole, forming a dynamic water storage layer (water level height = distance from through hole a to the bottom). The water in the second shell 21 can reduce the evaporation rate of the first shell 11. The double-layer structure forms a water interlayer, inhibiting the heat conduction of the soil and the photolysis reaction of the trap. Thus, rainwater can be stored during rainy weather to maintain the humidity of the trapping medium. On sunny days, it can be used to enhance the diffusion efficiency of volatile traps (such as sex pheromones). The water level in the storage layer rises to form a "wet trap," causing insects to slide into the mixed medium in the first receiving cavity A for killing. This method reduces the frequency of human intervention and maintenance pressure compared to traditional traps. Furthermore, due to the liquid level difference between the first radial through hole a and the second radial through hole b, the trapping medium is difficult to flow out through through hole b.

[0029] In summary, this application provides a simple partially buried insect trap 100, in which the first shell 11 forms a "water level threshold control" with the second shell 21 through the first radial through-hole a. When there is no rainfall, the water storage layer (height = distance from through-hole a to the bottom) is kept moist by artificial water replenishment or natural dew, ensuring that the trapping medium (such as sticky insect glue, sex pheromone slow-release tablets) continues to function; when it rains, after the water level exceeds through-hole a, the excess water is discharged through the second radial through-hole b (horizontal drainage), preventing the medium from spreading out from the opening of the inner container; the double-layer through-hole design realizes "graded drainage".

[0030] When the relative rainfall is low, the water level will not exceed the through hole a; conversely, when the rainfall is high, the second radial through hole b will be activated, and the water will be quickly diverted to the surrounding land, which is especially suitable for areas with large interannual fluctuations in rainfall.

[0031] The insect trap also includes a base 30, which includes a first part 31 and a second part 32. The first part 31 is in contact with the bottom of the trench into which the insect trap is buried, and the second part 32 creates a gap between the bottom wall of the second housing 21 and the bottom of the trench.

[0032] Understandably, the second part 32 separates the bottom wall of the second shell 21 from the bottom of the tank to form a flow (about 2-3 cm high), preventing rainwater or irrigation water from accumulating at the bottom of the trap; reducing soil moisture erosion of the bottom of the shell and extending the service life of the trap. At the same time, the space between the second part 32 can serve as a drainage buffer, guiding rainwater to drain quickly from the bottom of the trap and preventing mud and sand from directly contacting the shell openings and causing blockage.

[0033] Whether to use base 30 depends on soil type, climate conditions, and installation location. For example, it is preferred to use base 30 in areas with high rainfall or hard surfaces.

[0034] The inner container 10 includes a fence 13, and the cover 12 is connected to the opening end of the first housing 11 through the fence 13, so that there is a gap between the cover 12 and the opening of the first housing 11; the cover 12 and the first housing 11 form a directional channel through the fence 13, and the gap width only allows the target insects to enter, while preventing large organisms (such as rodents) from destroying the trap; the cover 12 blocks direct rainwater, preventing rainwater from directly entering the first containment cavity A, protecting the sticky insect glue or agent from being diluted, and leaves, dust and other debris are intercepted outside by the fence 13, improving the cleanliness of the interior.

[0035] The cover 12 includes a central portion 121 and an edge portion 122. The edge portion 122 protrudes radially from the first housing 11 and a plurality of water guiding holes d are provided at the edge portion 122. The diameter of the second housing 21 gradually increases in the direction away from the cover 12 to form a water guiding surface on the outer wall of the second housing 21. Rainwater passing through the water guiding holes d falls onto the water guiding surface.

[0036] Understandably, the water guide hole d of the edge portion 122 directs the rainwater intercepted by the cover 12 to the outer wall of the second shell 21, preventing rainwater from accumulating on the top of the cover 12 or flowing back to the first receiving cavity A along the outer wall of the first shell 11; the conical outer wall (tilt angle 15°-20°) of the second shell 21 forms a water guide surface, and the rainwater slides down quickly along the water guide surface. The water guide hole d → water guide surface, ensuring that it does not contact the bottom medium inside the first shell 11 during rainfall. At the same time, the conical design of the second shell 21 lowers the center of gravity, and with the support of the base 30, the wind resistance is improved, reducing the risk of tipping over in soft soil.

[0037] Furthermore, the side of the central portion 121 facing away from the first housing 11 adopts a curved or inclined surface from the center outward; the curved or inclined surface (inclination angle 5°-10°) of the central portion 121 quickly guides rainwater to the water guide hole d of the edge portion 122, avoiding rainwater from accumulating on the top of the cover to form a puddle. At the same time, the arc transition of the curved / inclined surface can buffer the impact force of rainwater and reduce the risk of rainwater splashing into the first receiving cavity A.

[0038] The first housing 11 includes a mounting portion 111 and a body portion 112 along the axial direction. The mounting portion 111 protrudes radially relative to the body portion 112. When the inner container 10 is assembled inside the outer container 20, a portion of the mounting portion 111 abuts against the end of the second housing 21.

[0039] Specifically, the radially protruding annular structure of the mounting part 111 is used to mechanically limit the inner container 10 with the end of the second shell 21 of the outer container 20, ensuring the axial positioning of the inner container 10 within the outer container 20; the body part 112 is a cylindrical body that contains the trapping medium, and its outer diameter is slightly smaller than the inner diameter of the second shell 21 for easy insertion. The protruding design of the mounting part 111 forms a "step," and the user only needs to push the inner container 10 axially into the outer container 20 until the mounting part 111 abuts against the end of the second shell 21 to complete the positioning without additional adjustment. The operator only needs to align the mounting part 111 of the inner container 10 with the opening of the outer container 20 and push it in axially until the mounting part 111 is completely fitted with the end of the second shell 21 to complete the assembly without tools or rotation.

[0040] The mounting part 111 is provided with several grip openings 111a, each grip opening 111a being a notch recessed inward relative to the outside of the mounting part 111. The grip openings 111a are arc-shaped or rectangular notches, evenly distributed on the radial protruding ring of the mounting part 111, usually two or four notches, to ensure that the user can grip from different angles. The inner wall of the notch can be designed with a frosted surface or horizontal stripes to increase the friction between the fingers and the grip openings 111a and prevent slippage during disassembly.

[0041] The following is an analysis of the installation steps and base adaptation design of insect traps, with point-by-point explanations based on land adaptability, ease of installation, and structural stability requirements: Trench pretreatment: The user first digs a trench in the ground with a diameter slightly larger than that of the outer container 20 (about 15-20cm deep) to ensure that the outer container 20 can be vertically embedded.

[0042] Pressure compression fixation: In soft soil, directly press the outer container 20 vertically into the trench and fix it by soil friction; if the soil is hard or dry, it needs to be installed with the base 30. The base 30 raises the outer container 20 by about 3-5cm to prevent it from being completely buried in hard soil.

[0043] Align the mounting part 111 of the inner container 10 with the opening of the outer container 20; push it in axially until the mounting part 111 abuts the end of the outer container 20 (as described above); confirm that there is no shaking between the inner container 10 and the outer container 20, and the assembly is complete; cover the opening end of the first shell 11 with loose soil (about 5-8 cm high), leaving only the fence 13 exposed (about 3-5 cm high), ensuring that insects can enter through the fence 13, while preventing debris or rainwater from directly entering. The strip-shaped openings (about 2-3 mm wide) of the fence 13 remain ventilated after burying; then add the induction medium to complete the setup.

[0044] When cleaning and updating the induction medium is required, simply clean the soil from the opening end of the first housing 11, press your finger against the handle 111a, and apply a uniform axial pulling force to pull out the inner container 10; the outer container 20 can remain fixed in the ground, and there is no need to move it when cleaning or updating the medium, thus avoiding repeated digging of trenches or adjustment of angles.

[0045] The technical features described above can be combined arbitrarily. Although possible combinations of these technical features are not described, any combination of these technical features should be considered to be covered by this specification, provided that such combination does not contain contradictions.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; although this application has been described in detail with reference to the previous embodiments, those skilled in the art should understand that they can still adjust the technical solutions described in the previous embodiments, or make equivalent substitutions for some or all of the technical features; and these adjustments or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
