Description

Technical Field

[0001] This utility model relates to the field of insect control devices, and in particular to an insect control device for rice cultivation. Background Technology

[0002] Rice pest control devices are primarily used to protect rice from pests during the growing process, ensuring both yield and quality. These devices can be widely applied in various rice-growing areas, from large-scale farms to small family plots. Current practical applications typically require the following technologies:

[0003] 1. Highly efficient trapping and repelling technologies, such as special light sources, odor attractants, and sound wave repelling devices;

[0004] 2. Durable and easy-to-maintain materials and structure, adaptable to different farmland environments and climatic conditions.

[0005] Currently, various equipment, methods, and approaches are used to achieve pest control in rice cultivation.

[0006] For example, a Chinese patent discloses a rice-growing insect-repelling device (patent number: CN208821525U). This device utilizes a motor with a rotating base and grinding teeth at the bottom, in conjunction with a shell on the inner wall of the bottom, to trap pests using pheromone traps and a trapping lamp. The pests enter the shell through trapping holes and are killed by an electric grid. Their bodies fall onto a guide block's slope and slide into the gap between the rotating base and the inner wall of the shell. Driven by the motor, the interlaced grinding teeth break them down, creating fertilizer for rice cultivation. This avoids the need for timed pest cleaning and improves ease of use. Simultaneously, through the cooperation of a solar panel and a fan blade, when the fan blade rotates at a high speed, the AC motor reverses. At this time, the control unit cuts off the battery's power supply to the motor, and the fan blade drives the motor's rotating shaft to reverse, generating electricity to provide additional energy to the battery. This also drives the rotating base to rotate and grind the pests, and the fan blade's rotation further disperses the pheromones from the pheromone traps. This solves the problem of power supply stability while improving the trapping efficiency of the rice-growing insect-repelling device.

[0007] However, the above method has a prominent problem: the support rod in the device is relatively fixed and lacks lifting and adjustment function. It cannot adjust the height according to the actual terrain and water level changes of the paddy field, resulting in poor adaptability. When facing different placement requirements, additional support structures need to be built to achieve the appropriate height, which increases the difficulty of installation and use. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a rice planting insect-proof device that solves the technical problems of relatively fixed support rods, lack of lifting and adjustment functions, inability to adjust height according to actual terrain and water level changes in paddy fields, poor adaptability, and the need to build additional support structures to achieve appropriate heights when facing different placement requirements, which increases the difficulty of installation and use.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A rice-growing insect-proof device includes a support rod, a worm gear rotatably connected inside the support rod, a worm wheel rotatably connected inside the support rod, the worm gear and the worm wheel meshing with each other, an externally threaded rod threadedly connected inside the worm wheel, the externally threaded rod slidably connected inside the support rod, a sliding adjustment rod sleeved on the upper end of the externally threaded rod, the sliding adjustment rod slidably connected inside the support rod, and the insect-proof device body fixedly connected to the upper end of the sliding adjustment rod.

[0011] Preferably, the worm gear has a threaded groove inside, and the external threaded rod is threaded into the threaded groove.

[0012] Preferably, the support rod is internally fixedly connected to an arc-shaped limiting block, and the external threaded rod has a limiting groove inside.

[0013] Preferably, the arc-shaped limiting block is slidably connected inside the limiting groove, and a set of trapping holes are opened inside the insect-proof device body.

[0014] Preferably, an annular mounting base is fixedly connected to the outer surface of the sliding adjustment rod, and a set of sleeves is fixedly connected to the lower end of the annular mounting base.

[0015] Preferably, each of the sleeves has a sliding rod slidably connected to its outer surface, and each of the sliding rods has a ground nail inside it.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When facing different placement requirements, the user holds the worm gear and screws it. The worm gear rotates and engages with the worm wheel, which is connected to the external threaded rod. When the worm wheel rotates, it will drive the external threaded rod to slide vertically upward. The placement height of the insect-repelling device can be adjusted by sliding the external threaded rod lifting and adjusting the rod, so as to adapt to different insect-killing placement requirements.

[0018] Second, all four sliding rods are inserted into the ground through internally installed ground nails. The sliding rods slide inside the sleeves to form telescopic support rods. With the cooperation of the four sleeves and sliding rods with the support rods, not only is additional support provided during installation, enhancing the stability of the device, but the four sleeves and sliding rods, whose telescopic distance can be adjusted individually, can adapt to more installation environments.

[0025] This application provides a rice pest control device that effectively solves the problems of relatively fixed support rods, lack of height adjustment function, inability to adjust height according to actual terrain and water level changes in paddy fields, poor adaptability, and the need to build additional support structures to achieve suitable heights when facing different placement requirements, increasing the difficulty of installation and use. When facing different placement requirements, the user holds the worm gear and screws it. The worm gear rotates and engages with the worm wheel, which is threadedly connected to the external threaded rod. When the worm wheel rotates, it drives the external threaded rod to slide vertically upward. The placement height of the pest control device body can be adjusted by sliding the external threaded rod to meet different pest control placement requirements.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that the support rod in the device is relatively fixed, lacks lifting and adjustment function, cannot be adjusted according to the actual terrain and water level changes of the paddy field, has poor adaptability, and requires additional support structure to achieve the appropriate height when facing different placement requirements, which increases the difficulty of installation and use. The overall idea is as follows: A rice planting insect prevention device includes a support rod 11, a worm gear 12 rotatably connected inside the support rod 11, a worm wheel 13 rotatably connected inside the support rod 11, the worm gear 12 and the worm wheel 13 meshing, and an externally threaded rod 14 threadedly connected inside the worm wheel 13. 14 is slidably connected inside the support rod 11. The upper end of the external threaded rod 14 is sleeved with a sliding adjustment rod 15. The sliding adjustment rod 15 is slidably connected inside the support rod 11. The upper end of the sliding adjustment rod 15 is fixedly connected to the insect-proof device body 16. When facing different placement requirements, the user holds the surface of the worm 12 and screws it. The worm 12 rotates and engages, driving the worm wheel 13 to rotate. The worm wheel 13 and the external threaded rod 14 are threadedly connected. When the worm wheel 13 rotates, it will drive the external threaded rod 14 to slide vertically upward. The external threaded rod 14 lifts the sliding adjustment rod 15 to slide, thereby adjusting the placement height of the insect-proof device body 16 to adapt to different insect-killing placement requirements.

[0028] The worm gear 13 has a threaded groove 17 inside, and the external threaded rod 14 is threadedly connected to the inside of the threaded groove 17. The support rod 11 has an arc-shaped limiting block 18 fixedly connected inside, and the external threaded rod 14 has a limiting groove 19 inside. The arc-shaped limiting block 18 is slidably connected to the limiting groove 19. The insect-proof device body 16 has a set of trapping holes 21 inside. The support rod 11 is inserted into the rice planting field. The insect-proof device body 16 is supported by the support rod 11 and the sliding adjustment rod 15. The sliding adjustment rod 15, which slides in the support rod 11, can adjust the placement height of the insect-proof device body 16. The insect-proof device body 16 contains a trapping lamp that attracts insects. The trapping lamp emits light to attract insects to fly into the insect-proof device body 16 along the trapping holes 21. The electric grid set in the insect-proof device body 16 kills and expels the insects, thereby reducing the damage caused by insects to the rice crops.

[0029] An annular mounting base 22 is fixedly connected to the outer surface of the sliding adjustment rod 15. A set of sleeves 23 is fixedly connected to the lower end of the annular mounting base 22. Sliding rods 24 are slidably connected to the outer surface of each set of sleeves 23. Ground nails 25 are set inside each set of sliding rods 24. When the device is installed and positioned, the multiple sliding rods 24 set at the lower end of the annular mounting base 22 are pulled to fit against the ground. The four sliding rods 24 are inserted into the ground through the ground nails 25 set inside. The sliding rods 24 slide in the sleeves 23 to form a telescopic rod-type support rod. The four sleeves 23 and sliding rods 24 cooperate to support the insertion rod 11. When providing installation support, it not only provides additional support and enhances the stability of the device placement, but also allows the four sleeves 23 and sliding rods 24, whose telescopic distance can be adjusted independently, to adapt to more installation environments.

[0030] To address the problems existing in the prior art, this utility model provides a rice planting insect-proof device. When facing different placement requirements, the user holds the surface of the worm 12 and screws it. The rotation of the worm 12 engages with the worm wheel 13, which rotates. The worm wheel 13 and the external threaded rod 14 are threadedly connected. When the worm wheel 13 rotates, it will drive the external threaded rod 14 to slide vertically upward. The external threaded rod 14 lifts and slides the sliding adjustment rod 15 to adjust the placement height of the insect-proof device body 16, adapting to different insect-killing placement requirements.

[0031] Support rod 11: As the main support structure of the entire device, it is inserted into the rice planting field to provide a foundation for the installation and support of other components;

[0032] Worm 12: Drives worm wheel 13 to rotate through the user's turning operation, and is the power input component for adjusting the height;

[0033] Worm gear 13: meshes with worm 12, converting the rotational motion of worm 12 into the vertical lifting motion of external thread rod 14;

[0034] External thread rod 14: threadedly connected to worm gear 13, it slides vertically upward when worm gear 13 rotates, lifting sliding adjustment rod 15 to achieve height adjustment;

[0035] Sliding adjustment rod 15: It is sleeved on the upper end of the external thread rod 14 and slides as the external thread rod 14 is lifted, thereby driving the insect-proof device body 16 to adjust its height;

[0036] Insect control device body 16: It is equipped with trapping lights and electric grids inside to attract and kill pests, reducing damage to rice crops;

[0037] Threaded groove 17: It is formed inside the worm gear 13 and is used to connect with the external threaded rod 14 to realize transmission;

[0038] Arc-shaped limiting block 18: Fixed inside the support rod 11, it cooperates with the limiting groove 19 inside the external thread rod 14 to restrict the rotation of the external thread rod 14, so that it can only slide vertically.

[0039] Limiting groove 19: It is formed inside the external thread rod 14 and cooperates with the arc-shaped limiting block 18 to ensure the movement direction of the external thread rod 14;

[0040] Trapping hole 21: It is opened inside the insect-proof device body 16, allowing pests to fly in and guiding them into the insect-proof device body 16 for elimination.

[0041] Annular mounting base 22: fixed to the outer surface of the sliding adjusting rod 15, providing an installation position for the sleeve 23;

[0042] Sleeve 23: Fixed to the lower end of the annular mounting base 22, it cooperates with the sliding rod 24 to form a telescopic rod-type support rod, providing additional support for the device;

[0043] Sliding rod 24: It is slidably connected to the outer surface of sleeve 23 and has a ground nail 25 inside. By inserting it into the ground, it enhances the stability of the device.

[0044] Ground nail 25: Set inside the sliding rod 24, inserted into the ground, to further secure the device.

[0045] Working principle:

[0046] The first step is to insert the support rod 11 into the rice planting field. The support rod 11 and the sliding adjustment rod 15 support the insect-proof device body 16. The sliding adjustment rod 15, which slides inside the support rod 11, can adjust the placement height of the insect-proof device body 16. The insect-proof device body 16 contains a trapping lamp that attracts insects. The trapping lamp emits light to attract insects to fly into the insect-proof device body 16 through the trapping hole 21. The electric grid set inside the insect-proof device body 16 kills and expels the insects, thereby reducing the damage caused by insects to the rice crops.

[0047] The second step involves the user holding the worm gear 12 and turning it to meet different placement height requirements. The worm gear 12 rotates and engages with the worm wheel 13, which is threadedly connected to the external threaded rod 14. When the worm wheel 13 rotates, it drives the external threaded rod 14 to slide vertically upwards. The external threaded rod 14 lifts and slides the sliding adjustment rod 15 to adjust the placement height of the insect-repelling device body 16, adapting to different insect-killing placement requirements. During the installation and positioning operation, the multiple sliding rods 24 at the lower end of the annular mounting base 22 are pulled to fit against the ground. All four sliding rods 24 are inserted into the ground through the internal ground nails 25. The sliding rods 24 slide within the sleeve 23 to form a telescopic support rod. The four sleeves 23 and sliding rods 24 work together to support the insertion rod 11, providing additional support and enhancing the stability of the device placement. Furthermore, the four individually adjustable sleeves 23 and sliding rods 24 can adapt to more installation environments.

[0048] 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.
