Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology and relates to an insecticidal device for rice planting and management. Background Technology

[0002] Pest and disease control is required at different stages of rice cultivation, mainly through biochemical methods. Physical pest control is less commonly used due to its high cost (management and equipment costs), low safety, and unclear effectiveness. Of course, another important reason is that physical methods can generally only treat pests after they have emerged from the molt stage, while rice has many types of pests and diseases that pose a threat even before emergence.

[0003] This solution provides a physical pest control method, primarily targeting pests after they emerge from their molted stage, such as rice planthoppers and rice skippers. Existing pest control methods are generally photo-attracting and electrocution-based, which have significant drawbacks, especially in the control of rice pests and diseases. Firstly, rice paddies are mostly wet and watery, and electrocution methods pose safety hazards and grounding failure risks, making them unreliable and unsafe for management. Secondly, they are complex in structure and costly. Thirdly, existing pest control devices are mostly mesh structures, requiring frequent cleaning of insect carcasses, resulting in high operating costs, and the pest control effect is significantly affected over time. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing an insecticidal device for rice planting management. The technical problem to be solved by this invention is an optimized structure that eliminates the need to clean up insect carcasses.

[0005] The purpose of this utility model can be achieved through the following technical solution: an insecticidal device for rice planting management, characterized in that it includes a box with an open bottom, a battery mounting box located inside the box, a light source located at the bottom of the battery mounting box, and two insect-attracting units symmetrically arranged on both sides of the light source. The insect-attracting unit includes an insect-attracting inlet on the side wall of the upper part of the box, a first reflector, and a second reflector. A light-guiding channel connecting the insect-attracting inlet and the lower opening of the box is formed between the side wall of the battery mounting box and the side wall of the box. The first reflector and the second reflector are parallel. The light emitted by the light source can be guided to the outside of the insect-attracting inlet through the first reflector and the second reflector in sequence. A throat located below the light source is formed between the two first reflectors.

[0006] Furthermore, the lower part of the battery mounting box is wedge-shaped with the larger end facing upwards. Several protective plates are suspended on the wedge-shaped surface of the battery mounting box. The upper end of the protective plate is connected to the side wall of the battery mounting box, and the lower end of the protective plate hangs freely.

[0007] Furthermore, the side wall of the box cylinder has a perforated section located below the first reflector, the perforated section consisting of several small holes formed on the side wall of the box cylinder to prevent pests from passing through.

[0008] Furthermore, the mirror surface of the first reflector is tilted at an angle of 30 to 60 degrees to the horizontal plane.

[0009] Furthermore, the battery mounting box is equipped with a storage battery that powers the light source, and the top of the box is equipped with a photovoltaic panel that powers the storage battery.

[0010] Furthermore, the first reflector is a detachable component.

[0011] Furthermore, there are gaps between adjacent protective panels, and the protective panels are made of transparent plastic.

[0012] Furthermore, the bottom of the box cylinder is provided with an insertion stake that allows the box body to be vertically fixed in the soil.

[0013] This scheme utilizes the "periscope" principle, placing the light source in the lower middle part of the box cylinder. This allows emerging pests to be induced into the light guide channel. Due to phototaxis, most pests entering the light guide channel tend to contact the light source or continue to descend to enter the area under the two first reflectors from their throats. Pests located under the two first reflectors are trapped because their upward movement is obstructed and the lower space is spacious. Due to frequent contact with water and mud, and mutual damage among high-density pests, the pests below the first reflectors are collected in the paddy field at the bottom of the box cylinder, thus eliminating the need for cleaning up the pest corpses.

[0014] To elaborate further, regarding the insect attraction: After entering through the insect-attracting inlet, pests travel upstream into the light guide channel. The suspended protective plate negatively influences the pests' resting position. Once inside the area below the light source, the protective plate acts as a "backstop," limiting the pests' upward movement to some extent. The swaying of the protective plate originates from the pests' contact with it, as well as from the airflow entering the box from the insect-attracting inlet. The swaying protective plate drives and disturbs the pests, causing some to fall to the vicinity of their throats, thus trapping them in the area below the first reflector. The airflow enters through the insect-attracting inlet and exits through the perforated section at the bottom of the box, which can also... To a certain extent, this increases the probability of pests moving along the set path and also increases the shaking frequency of the protective plate, accelerating the descent of pests and minimizing their dwell time in the light guide channel. Regarding pest removal: since the trapped pests fall directly into the rice paddy, there is no need for tedious cleaning; only periodic relocation is required. In addition to dispersing pests, the protective plate also protects the light source to some extent, preventing pests from contacting and contaminating it as they descend. Even if the first reflector is contaminated, some light can still be guided outwards towards the insect-attracting entrance through the second reflector.

[0015] Depending on the needs, this insecticidal device can be used when the field is flooded or dry. When the field is flooded, the insecticidal time is shorter after the pests are trapped, the probability of them returning is lower, the insecticidal effect is better, and the maintenance cycle is longer. In addition, if there is a rice paddy, the area below the throat will also reflect light on the water surface, making it more likely for pests to descend. This is equivalent to the box below the light source being brighter, and the pests' phototactic activity under the first reflector will be more frequent, allowing them to die from fatigue and collisions more quickly.

[0016] When using it, insert the insertion stake at the bottom of the box into the soil of the paddy field or seedbed, ensuring that the opening at the bottom of the box is sealed with soil or water, and that some of the small holes in the hollow part are above the soil or water surface, with one of the insect-attracting entrances facing the wind direction as much as possible; change the placement of the box in the field regularly.

[0017] This method is the optimal way to use the insecticidal device. The insecticidal function can still be achieved without following this method. For example, if the box is inserted deeper or shallower, there may be an insect-attracting effect and some pests may escape, but this will not affect the overall feasibility.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 , Figure 2 and Figure 3The insecticidal device shown includes a box 1 with an opening at the bottom, a battery mounting box 2 located inside the box 1, a light source located at the bottom of the battery mounting box 2, and two insect-attracting units symmetrically arranged on both sides of the light source. The insect-attracting unit includes an insect-attracting inlet 3 on the upper side wall of the box 1, a first reflector 4, and a second reflector 5. A light-guiding channel 6 is formed between the side wall of the battery mounting box 2 and the side wall of the box 1, connecting the insect-attracting inlet 3 and the lower opening of the box 1. The first reflector 4 and the second reflector 5 are parallel, and the light emitted by the light source can be guided to the outside of the insect-attracting inlet 3 through the first reflector 4 and the second reflector 5 in sequence. A throat 7 is formed between the two first reflectors 4 located below the light source.

[0024] The lower part of the battery mounting box 2 is wedge-shaped with the larger end facing upwards. Several protective plates 8 are suspended on the wedge-shaped surface of the battery mounting box 2. The upper end of the protective plate 8 is connected to the side wall of the battery mounting box 2, and the lower end of the protective plate 8 hangs freely.

[0025] The side wall of the box cylinder 1 has a perforated part 9 located below the first reflector 4. The perforated part 9 consists of several small holes opened on the side wall of the box cylinder 1 to prevent pests from passing through.

[0026] The mirror surface of the first reflector 4 is tilted at an angle of 30 to 60 degrees to the horizontal plane.

[0027] The battery mounting box 2 is equipped with a storage battery 10 that powers the light source, and the top of the box cylinder 1 is equipped with a photovoltaic panel 11 that powers the storage battery 10.

[0028] The first rearview mirror 4 is a detachable component.

[0029] There is a gap between adjacent protective plates 8, and the protective plates 8 are made of transparent plastic.

[0030] The bottom of the box cylinder 1 is provided with an insertion stake 12 that can fix the box body vertically in the soil.

[0031] This scheme utilizes the "periscope" principle, placing the light source in the lower middle part of the box cylinder 1, so that emerging pests can be induced into the light guide channel 6. Due to phototaxis, most of the pests entering the light guide channel 6 tend to contact the light source or continue to descend to enter the two first reflectors 4 from the throat 7. The pests located under the two first reflectors 4 are trapped because their upward movement is obstructed and the lower space is spacious. Due to frequent contact with water and mud, and mutual damage among the high-density pests, the pests below the first reflectors 4 are collected in the paddy field at the bottom of the box cylinder 1, thus eliminating the need for cleaning of the pest corpses.

[0032] As a more detailed explanation, regarding the insect attraction: After entering through the insect attraction inlet 3, the pests travel upstream into the light guide channel 6. The suspended protective plate 8 negatively influences the pests, causing them to rest on it. Once inside the area below the light source, the protective plate 8 acts as a "backstop," limiting the pests' upward movement to some extent. The shaking of the protective plate 8 originates from the pests' contact with it, as well as from the airflow entering the box 1 from the insect attraction inlet 3. The shaking of the protective plate 8 drives and disturbs the pests, causing some to fall to the vicinity of their throats 7, and then enter the area below the first reflector 4, where they are trapped. The airflow enters through the insect attraction inlet 3 and exits through the perforated section 9 at the bottom of the box 1. This can also increase the probability of pests moving along the set path to a certain extent, and can also increase the shaking frequency of the protective plate 8, accelerating the descent of pests and minimizing the time pests spend in the light guide channel 6. As for pest removal: since the pests fall directly into the paddy field after being trapped, there is no need for tedious cleaning; it is only necessary to change the placement position periodically. In addition to dispersing pests, the protective plate 8 can also protect the light source to a certain extent, preventing the light source from being contaminated when the pests descend. Even if the first reflector 4 is contaminated, some light can still be guided outwards to the insect-attracting entrance 3 through the second reflector 5.

[0033] Depending on the needs, this insecticidal device can be used when the field is flooded or dry. When the field is flooded, the insecticidal time is shorter after the pests are trapped, the probability of them returning is lower, the insecticidal effect is better, and the maintenance cycle is longer. In addition, if there is a rice paddy, the area below the throat 7 will also reflect light on the water surface, making it more likely for pests to descend. This means that the box 1 below the light source is also brighter, and the phototactic activity of pests below the first reflector 4 is more frequent, allowing pests to die from fatigue and collisions more quickly.

[0034] When using, insert the insertion stake 12 at the bottom of the box 1 into the soil of the paddy field or seedbed, ensuring that the opening at the bottom of the box 1 is sealed by soil or water, and that some of the small holes in the hollow part 9 are above the soil or water surface, with one of the insect-attracting entrances 3 facing the wind direction as much as possible; change the placement of the box 1 in the field regularly.

[0035] This method is the optimal way to use the insecticidal device. The insecticidal function can still be achieved without following this method. For example, if the box 1 is inserted deeper or shallower, there may be an insect-attracting effect and some pests may escape, but this will not affect the overall feasibility.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
