Description

Technical Field

[0001] This utility model relates to the field of pest control technology in rice paddies, and in particular to a flying insect trapping device for rice paddies. Background Technology

[0002] In rice cultivation, pests such as the rice stem borer and the rice leaf roller are important factors affecting rice yield. Pest control is also an important task in rice cultivation. Among them, solar-powered insecticidal lamps use solar panels as a power source, storing the electricity generated by the sun during the day and discharging it to the insecticidal lamps at night. This attracts pests to the light source, and the electric grid outside the light source kills the pests, making it a highly efficient pest control method.

[0003] However, after flying insects are electrocuted by the electric grid, their corpses easily adhere to the grid wires due to body fluid adhesion and electrostatic adsorption. As the insect corpses accumulate, they form irregular obstructions on the grid surface. This weakens the light penetration of the attractant lamp, reducing the effective insect-attracting range and lowering the insect-attracting efficiency. It also hinders the conduction of current in the grid, causing the actual voltage of the grid to drop. Rice planthoppers and stem borers that could be instantly electrocuted may escape with only minor injuries due to insufficient voltage, significantly reducing the success rate of capture. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a flying insect trapping device for rice paddies. It solves the problem that after flying insects are electrocuted, their carcasses easily adhere to the electric grid wires due to body fluids and electrostatic adsorption. This accumulation creates irregular obstructions, which weaken the attracting light and reduce the effective insect-attracting range. Furthermore, it hinders the current flow, causing a drop in grid voltage, allowing rice planthoppers and stem borers to escape with minor injuries, significantly reducing the success rate of insect capture.

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

[0006] A flying insect trapping device for rice paddies includes a support frame with an inner groove. Attracting lights are fixedly installed on the side walls of the support frame. Vertical rods are fixedly installed on the support frame, and a solar panel is fixedly installed between two vertical rods. Side strips are symmetrically installed on the support frame, and two electric grids are symmetrically installed on the two side strips. A drive motor is fixedly installed inside the inner groove, and a rotating shaft is installed at the output end of the drive motor. The rotating shaft is rotatably installed inside the support frame, and a scraper is fixedly installed on the rotating shaft, which is in contact with the two electric grids. A collection box is provided on the support frame, located below the electric grids. The solar panel provides independent power in the field, the attracting lights lure insects, the electric grids trap and kill them, the scraper automatically cleans up insect carcasses, and the collection box collects the insects, improving trapping efficiency and reducing manual maintenance.

[0007] Preferably, a first threaded ring is threadedly installed on the support, and an auxiliary support is fixedly installed at equal intervals at the lower end of the first threaded ring. The height of the auxiliary support can be changed by adjusting the first threaded ring to adapt to different growth stages of rice. The auxiliary support works in conjunction with the main support to enhance the stability of the equipment on muddy fields.

[0008] Preferably, the two electric grids are fixedly installed between the two side strips, and the side strips are in contact with the scraper strip. The side strips firmly fix the electric grids and prevent them from loosening. The scraper strip is in contact with the side strips for cleaning, which can simultaneously remove the electric grids and insect carcasses from the side strips, ensuring that there are no dead corners in the cleaning.

[0009] Preferably, a sealing plate is fixedly fitted on the attracting light. The sealing plate covers the connection parts of the attracting light, side strips and electric grid. The sealing plate covers the key connection parts, preventing mud and rainwater from entering the field, preventing short circuits and component corrosion, and extending the service life of the equipment.

[0010] Preferably, the vertical poles are symmetrically fixed on both sides of the bracket, and the vertical poles extend upward perpendicular to the bracket. The solar panels are horizontally mounted on the top of the two vertical poles, and the vertical poles support the solar panels to a high position, avoiding shading by rice plants, ensuring full sunlight reception, improving light energy conversion efficiency, and ensuring sufficient power supply for the equipment.

[0011] Preferably, the bracket is threaded with a second threaded ring, and a collection box is fixedly installed on the second threaded ring. The collection box is open at the top, and the threaded connection facilitates quick assembly and disassembly of the collection box. The open design at the top maximizes the collection of insect carcasses, reduces the scattering of insect carcasses, and reduces the difficulty of cleaning.

[0012] Preferably, the collection box has a detachable collection base plate inside, one side of which extends out of the collection box to form an extension that is easy to pull out. The pull-out base plate makes it convenient to operate and clean on the field ridge without disassembling the collection box, thus avoiding the spillage of insect carcasses and facilitating thorough cleaning.

[0013] Preferably, the scraper is configured to correspond to two electric grids, and the length of the scraper is adapted to the height of the electric grids. The scraper corresponds to the electric grids and the length is adapted, so that it can completely cover the surface of the electric grids, thoroughly remove insect carcasses, and ensure the conductivity of the electric grids and the light transmittance of the attracting lamps.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device achieves self-powered operation in rice paddies without external power supply through solar panels. It is equipped with attractant lights for precise insect attraction and electric grids for efficient insect killing. At the same time, a drive motor drives scrapers to automatically clean up insect carcasses in the electric grids to prevent a decrease in killing efficiency. Finally, insect carcasses are collected in a collection box. The whole system is integrated and highly adaptable to rice paddy field scenarios, achieving low-maintenance and continuous high-efficiency killing of flying insects. Attached Figure Description

[0022] This application provides a flying insect trapping device for rice paddies, effectively solving the problem that after flying insects are electrocuted, their corpses easily adhere to the electric grid wires due to body fluid adhesion and electrostatic adsorption. The irregular blockage formed by the accumulation weakens the attraction light and reduces the effective insect-attracting range, and also hinders the current, causing a drop in grid voltage. This allows rice planthoppers and stem borers to escape with minor injuries, significantly reducing the success rate of capture. This device achieves self-powered operation in rice paddies without external power supply through solar panels. Combined with the attraction light for precise insect attraction and the electric grid for efficient insect killing, a drive motor drives a scraper to automatically clean the insect corpses from the grid to prevent a decrease in capture efficiency. Finally, the insect corpses are collected in a collection box. The entire system is integrated and highly adaptable to rice paddy environments, achieving low-maintenance and continuous high-efficiency capture of flying insects.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that after flying insects are electrocuted by the electric grid, their corpses easily adhere to the grid wires due to body fluid adhesion and electrostatic adsorption. The irregular obstruction formed by the accumulation weakens the light of the attracting lamp, reduces the effective insect-attracting range, and also hinders the current, causing the grid voltage to drop, allowing rice planthoppers, stem borers, etc., to escape with minor injuries, greatly reducing the success rate of killing them. The overall idea is as follows: A flying insect killing device for rice paddies includes a support 1, which is a long and rigid structure with a rectangular inner groove 2 along its length. The depth and width of the inner groove 2 are adapted to the installation dimensions of the drive motor 11, ensuring that the drive motor 11 can be stably placed in the groove. The attracting lamp 5 is fixedly installed in the middle of the side wall of the support 1 by bolts, with its light emission direction horizontally facing the electric grid 8, and the axis of the attracting lamp 5 is parallel to the plane of the electric grid 8. Two vertical rods 9 are symmetrically welded to the two side walls of the bracket 1 and located above the attracting lamp 5. The spacing between the two vertical rods 9 is adapted to the width of the solar panel 10. The solar panel 10 is fixed to the top of the two vertical rods 9 with bolts, and is in a horizontal position. Its terminals are connected to the internal energy storage module of the equipment through wires. Two power grids 8 are located on the left and right sides of the attracting lamp 5, respectively, and are equidistant from the attracting lamp 5. The plane of the power grids 8 is perpendicular to the ground. The power grids 8 are connected to the power supply module of the equipment through wires. The drive motor 11 is fixed to the bottom of the inner groove 2 with bolts, and its output end faces upward. It is fixedly connected to the lower end of the rotating shaft 12 through a coupling. The rotating shaft 12 is a cylindrical structure, and its top end is rotatably connected to the inner wall of the inner groove 2 via a bearing. It can rotate around its own axis. The scraper 13 is fixed to the side wall of the rotating shaft 12 by bolts. The end of the scraper 13 away from the rotating shaft 12 is closely attached to the surface of the electric grid 8, and the length of the scraper 13 is the same as the height of the electric grid 8. When rotating, it can cover the entire surface of the electric grid 8. The collection box 15 is a box-shaped structure with an open top. It is fixed to the lower part of the bracket 1 by a connecting structure and is located directly below the two electric grids 8. Its opening size is larger than the maximum distance between the two electric grids 8, ensuring that all the insect corpses on the electric grid 8 can fall into the box.

[0025] A first threaded ring 3 is threaded onto the support 1, and auxiliary supports 4 are fixedly mounted at equal intervals at the lower end of the first threaded ring 3. The inner ring of the first threaded ring 3 has an internal thread that matches the external thread of the outer wall of the support 1. The threaded ring can rotate and move up and down along the axial direction of the support 1, and its installation position is close to the bottom end of the support 1. There are 3-4 auxiliary supports 4, which are rod-shaped structures and are fixed at equal intervals on the lower end face of the first threaded ring 3. Each auxiliary support 4 is inclined away from the support 1 at an angle of 30-45 degrees. The length of the auxiliary supports 4 is adapted to the depth of insertion into the field soil to ensure that it is not easy to tip over when supporting the equipment together with the support 1.

[0026] Side strips 7 are symmetrically fixedly installed on the bracket 1. Two electric grids 8 are respectively fixedly installed between the two side strips 7, and the side strips 7 are in contact with the scraper 13. The side strips 7 are two long, rigid structures, symmetrically fixed to the side wall of the bracket 1 and located on both sides of the attractant lamp 5. The length of the side strips 7 is the same as the height of the electric grids 8. The opposite side wall is provided with a slot for fixing the electric grids 8. The two electric grids 8 are respectively fixed between the two side strips 7 by the slots. The upper and lower ends of the electric grids 8 are flush with the upper and lower ends of the side strips 7, and the electric grids 8 are perpendicular to the side strips 7. While the scraper 13 is in contact with the electric grids 8, its side edge is also in close contact with the side wall of the side strips 7 near the electric grids 8, ensuring that the insect carcasses adhering to the surface of the side strips 7 can be cleaned simultaneously when rotating.

[0027] A sealing plate 6 is fixedly fitted onto the attractant light 5. The sealing plate 6 covers the connection points of the attractant light 5, the side strip 7, and the electric grid 8. The sealing plate 6 has a ring-shaped waterproof structure, and its inner diameter is adapted to the outer diameter of the attractant light 5. It is tightly fitted onto the outside of the attractant light 5 and fits snugly against the side wall of the bracket 1 without any gaps. The outer diameter of the sealing plate 6 covers the connection gap between the attractant light 5 and the bracket 1, the connection end between the side strip 7 and the bracket 1, and the connection end between the electric grid 8 and the side strip 7, completely blocking these areas and preventing mud and rainwater from seeping in.

[0028] Vertical poles 9 are symmetrically fixed on both sides of the bracket 1, extending upwards perpendicularly to the bracket 1. Solar panels 10 are horizontally mounted on the tops of the two vertical poles 9. The length of the vertical poles 9 is greater than the height of the rice plant at maturity, and they are welded perpendicularly to the side wall of the bracket 1 at a 90-degree angle. The tops of the vertical poles 9 are polished to ensure a smooth surface, and the tops of the two vertical poles 9 are at the same height. The bottom edge of the solar panel 10 is bolted to the connecting bracket at the top of the two vertical poles 9, ensuring that the solar panel 10 is always horizontal, with its light-receiving surface facing due south. Waterproof wires pass through the inside of the vertical poles 9 and connect to the energy storage battery of the device.

[0029] A second threaded ring 14 is threaded onto the bracket 1, and a collection box 15 is fixedly mounted on the second threaded ring 14. The collection box 15 is open at the top. The inner ring of the second threaded ring 14 has an internal thread that matches the external thread of the outer wall of the bracket 1. The installation position is directly below the electric grid 8. The threaded ring can be rotated along the axis of the bracket 1 to adjust its height. The collection box 15 has a cuboid structure, and its outer wall is welded to the inner ring of the second threaded ring 14. The upper opening of the collection box 15 is rectangular, and the edge of the opening is 5-8cm higher than the bottom of the electric grid 8. The inner wall of the box is polished to keep it smooth, so that the insect carcasses can slide to the bottom. The depth of the box is 15-20cm, which can hold a certain amount of insect carcasses.

[0030] The collection box 15 has a detachable collection base plate 16 installed inside. One side of the collection base plate 16 extends out of the collection box 15, forming an extension section that is easy to pull out. The collection base plate 16 is a rectangular plate that matches the internal cross-section of the collection box 15. The upper and lower ends of the inner sidewall of the collection box 15 are provided with sliding grooves along the length direction. The two sides of the base plate are embedded in the sliding grooves, and can be pulled out horizontally along the sliding grooves to achieve detachment. The extension section is a rectangular structure extending outward from one side of the base plate, with a length of 10-15cm. The surface of the extension section is provided with anti-slip texture, making it easy for users to grip and pull out. The width of the extension section is the same as that of the base plate, ensuring that the base plate will not shift when pulled out.

[0031] The scraper 13 is set for two electric grids 8, and the length of the scraper 13 is adapted to the height of the electric grid 8. The number of scraper 13 is the same as the number of electric grids 8. They are all fixed to the side wall of the rotating shaft 12 by welding. The angle between the two scraper 13 and the rotating shaft 12 is the same, ensuring that the two electric grids 8 are cleaned synchronously when rotating. The length of the scraper 13 is perfectly adapted to the height of the electric grid 8. The top of the scraper 13 is flush with the top of the electric grid 8, and the bottom is flush with the bottom of the electric grid 8. The end of the scraper 13 away from the rotating shaft 12 is made of flexible and wear-resistant material, which always fits tightly against the surface of the electric grid 8. There are no gaps when rotating, which can thoroughly scrape off the insect carcasses on the electric grid 8.

[0032] To address the problems existing in the prior art, this utility model provides a flying insect trapping device for rice paddies. This device achieves self-powered operation in rice paddies without external power supply through solar panels. It is combined with attractant lights for precise insect attraction and electric grids for efficient insect killing. At the same time, a drive motor drives scrapers to automatically clean the insect carcasses in the electric grids to prevent a decrease in killing efficiency. Finally, the insect carcasses are collected in a collection box. The whole device operates in an integrated manner, which is highly adaptable to the rice paddy field environment and achieves low-maintenance and continuous high-efficiency killing of flying insects.

[0033] Working principle:

[0034] In use, the first threaded ring 3 can be rotated on the support 1. The rotation of the first threaded ring 3 will drive the auxiliary support 4 to move up and down. After the first threaded ring 3 and the auxiliary support 4 are adjusted to a suitable height, the device can be inserted into the paddy field. At this time, the support 1 and the auxiliary support 4 are inserted into the paddy field to support the device. During the day, the device absorbs sunlight and stores energy through the solar panel 10. At night, the attractant light 5 will be lit. The light shines through the two electric grids 8 to attract flying insects. At this time, the device will power the two electric grids 8. After flying onto the electric grids 8, they will be electrocuted. Some of the dead flying insects will slide down the electric grids 8 to the collection box 15, and the other part will stick to the electric grids 8. At this time, the device can be controlled to intermittently start the drive motor 11. Under the action of the drive motor 11, the rotating shaft 12 will be rotated. The rotating shaft 12 will drive the scraper 13 to slide on the two electric grids 8 to scrape off the dead flying insects on the electric grids 8. The scraped dead insects will fall down the electric grids 8 into the collection box 15 and be collected.

[0035] 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
