Abstract
Description
Technical Field
[0001] This application relates to the field of insect control technology, and more specifically, to an insect control device for rice cultivation. Background Technology
[0002] Rice pest control devices are agricultural protective equipment used in rice cultivation to drive away pests through physical, chemical, or biological means, thereby reducing the damage caused by pests to rice growth, ensuring healthy rice growth, and improving rice yield and quality.
[0003] When the insect repellent device is running continuously, the dead mosquitoes killed by the electric grid tend to accumulate on the surface of the grid, which not only blocks the grid openings but also affects the normal voltage conduction of the grid. This results in mosquitoes not being effectively killed when they come into contact with the grid. The insect-catching efficiency decreases significantly with the extension of the usage time, and frequent manual cleaning is required to maintain basic functions, which increases the labor costs and maintenance burden of agricultural production.
[0004] In view of this, this application proposes a pest control device for rice cultivation. Utility Model Content
[0005] The purpose of this application is to provide a rice planting pest control device that solves the technical problems mentioned in the background art.
[0006] This application provides a rice planting insect repellent device, including a protective frame, an insect trapping component inside the protective frame, a fixing ring fixedly connected to the lower end face of the protective frame, and a placement box below the fixing ring.
[0007] The insect-catching assembly includes a support base located inside and below the protective frame. An insect-catching lamp is fixedly connected to the upper surface of the support base. An electric grid is provided around the insect-catching lamp, and the lower surface of the electric grid is fixedly connected to the support base. A sealing top plate is fixedly connected to the upper surface of the electric grid. A rotating strip is rotatably connected to the upper surface of the sealing top plate. Multiple protrusions are fixedly connected to the outer wall of the upper end of the electric grid. A connecting strip is fixedly connected to the lower part of one end of the rotating strip. An elastic block is fixedly connected to the end face of the connecting strip near the electric grid.
[0008] Optionally, a fixing frame is fixedly connected to the upper end face of the protective frame, and a photovoltaic panel is fixedly connected to the upper end face of the fixing frame.
[0009] Optionally, an external threaded ring is fixedly connected to the lower end face of the fixing ring, and the external threaded ring is rotatably connected to the placement box via a thread.
[0010] Optionally, the placement box has a grid frame inside.
[0011] Optionally, a motor is fixedly connected to the lower end face of the sealing top plate, and the output end of the motor is fixedly connected to the rotating bar.
[0012] Optionally, multiple connecting rods are fixedly connected between the support base and the fixing ring.
[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:
[0014] 1. This application utilizes a rotating bar and elastic blocks. The elastic blocks strike the protruding blocks of the electric grid, causing it to vibrate continuously and dislodge mosquitoes adsorbed on the grid. This prevents mosquitoes from accumulating and clogging the grid, ensuring the electric grid maintains its high-efficiency insect-catching state over a long period. The insect-attracting liquid inside the box releases an odor, which, combined with the light source of the insect-catching lamp at night, forms a dual insect-attracting mechanism with a wider coverage area. This effectively attracts various mosquitoes from the surrounding rice paddies to the electric grid, increasing the success rate of insect trapping.
[0015] 2. This application allows the placement box to be removed from the external threaded ring by rotating it. The mesh frame inside the placement box can filter and separate mosquitoes in the insect attractant liquid, so staff do not need to directly contact the insect attractant liquid, making cleaning more convenient. At the same time, the insect attractant liquid can be reused, reducing waste and lowering maintenance costs. Attached Figure Description

[0021] The present application will be further described in detail below with reference to the accompanying drawings.
[0022] Reference Figures 1-4This application provides a rice planting insect control device, including a protective frame 1. An insect-trapping component 4 is located inside the protective frame 1. A fixing ring 5 is fixedly connected to the lower end face of the protective frame 1, and a placement box 7 is located below the fixing ring 5. The insect-trapping component 4 includes a support base 401 located at the lower part of the protective frame 1. An insect-trapping lamp 402 is fixedly connected to the upper end face of the support base 401. An electric grid 403 is provided around the insect-trapping lamp 402, and the lower end face of the electric grid 403 is fixedly connected to the support base 401. A sealing top plate 404 is fixedly connected to the upper end face of the electric grid 403. A rotating bar 405 is rotatably connected to the upper end face of 404. Multiple protrusions 407 are fixedly connected to the outer wall of the upper end of the electric grid 403. A connecting bar 408 is fixedly connected to the lower end of one end of the rotating bar 405. An elastic block 409 is fixedly connected to the end face of the connecting bar 408 near the electric grid 403. As the rotating bar 405 and the elastic block 409 rotate, the elastic block 409 hits the protrusions 407 of the electric grid 403, causing the electric grid 403 to vibrate continuously, which knocks off the mosquitoes adsorbed on the net, preventing the mosquitoes from accumulating and clogging the electric grid, and ensuring that the electric grid 403 maintains a high-efficiency insect-catching state for a long time.
[0023] A fixed frame 2 is fixedly connected to the upper end of the protective frame 1, and a photovoltaic panel 3 is fixedly connected to the upper end of the fixed frame 2. A motor 406 is fixedly connected to the lower end of the sealed top plate 404, and the output end of the motor 406 is fixedly connected to the rotating bar 405. Multiple connecting rods 6 are fixedly connected between the support base 401 and the fixed ring 5. The photovoltaic panel 3 uses solar energy to power the device, without the need for an external power supply. It is suitable for installation in outdoor areas without power supply conditions, such as rice fields, reducing the cost of use, and is environmentally friendly and energy-saving. It can work continuously around the clock.
[0024] The lower end face of the fixing ring 5 is fixedly connected to an external threaded ring 9, and the external threaded ring 9 is connected to the placement box 7 by a threaded rotation. The interior of the placement box 7 is equipped with a mesh frame 8. The insect-attracting liquid inside the placement box 7 releases an odor, which, combined with the light source of the night-time insect-trapping lamp 402, forms a dual insect-attracting mechanism with a wider coverage area. This effectively attracts various mosquitoes and insects around the rice paddy to the electric grid 403, increasing the success rate of insect trapping. During later cleaning, the placement box 7 can be removed from the external threaded ring 9 by rotating it. The mesh frame 8 inside the placement box 7 can filter and separate the mosquitoes in the insect-attracting liquid, so workers do not need to directly contact the insect-attracting liquid, making cleaning more convenient. At the same time, the insect-attracting liquid can be reused, reducing waste and lowering maintenance costs.
[0025] Working principle: When in use, install the device on the fence beside the rice paddy, pour the insect-attracting liquid into the placement box 7, then place the mesh frame 8 into the placement box 7, and finally rotate the placement box 7 onto the external threaded ring 9. The photovoltaic panel 3 can charge the power supply inside the device, allowing it to operate normally at night. Activating the insect-catching lamp 402, the power grid 403, and the motor 406 causes the motor 406 to rotate, which in turn rotates the rotating bar 405. The rotating bar 405 then rotates the connecting bar 408 and the elastic block 409 synchronously. The elastic block 409 continuously impacts and passes through multiple protrusions 407 on the power grid 403, thereby causing the power grid 403 to vibrate.
[0026] The insect-attracting liquid inside the placement box 7 releases an odor to attract mosquitoes near the rice paddy. At night, the insect-catching light 402 also attracts mosquitoes, causing them to pass through the protective frame 1 and approach the electric grid 403. When a mosquito touches the electric grid 403, the electrified grid knocks it down. Some mosquitoes may get caught on the grid, but the vibration of the grid will bounce them off, preventing them from sticking to the grid and affecting later use. The fallen mosquitoes will pass through the fixing ring 5 and fall into the insect-attracting liquid in the placement box 7. When cleaning up the mosquitoes later, the placement box 7 can be rotated and removed, and the mesh frame 8 inside the placement box 7 can be taken out of the insect-attracting liquid. The mesh frame 8 will filter out the mosquitoes inside the insect-attracting liquid, making it easier for staff to clean up the mosquitoes inside the liquid without wasting the insect-attracting liquid.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
