Description

Technical Field

[0001] The utility model relates to the technical field of sound wave pest control, in particular to a pest interference device based on sound waves. Background Technique

[0002] In agricultural production, pests and diseases seriously threaten the yield of crops. Traditional pest control methods for crops have disadvantages such as environmental harm, high cost, low timeliness, and easy resistance of pests. Research shows that using sound wave resonance technology to control crop pests can not only well overcome the above disadvantages, but also sound wave radiation helps the growth of crops. A sound wave pest repellent is a device that drives pests in a region by generating sound waves of specific frequencies. The device is installed in farmland, warehouses or special areas, and emits specific sound waves to imitate various natural enemies of pests for plants, grains or woods where insects inhabit, so as to achieve the effect of driving away pests. The prior art discloses: a sound wave pest repellent interference device, with the publication number: CN113229268A, which drives two ultrasonic pest repellents to work by setting a control panel and two ultrasonic pest repellents. Through switch one, the two ultrasonic pest repellents are powered on to work, and then the insects can be interfered by sound waves. At the same time, the frequency of the sound waves can be adjusted through a frequency modulation module. However, the ultrasonic pest repellents are fixedly oriented in one direction. Obviously, the sound wave propagation is good and the pest control effect is good in the directly facing direction, while the sound wave propagation rate in other directions is relatively low and the pest control effect is poor, and it cannot drive pests in a large range well. If ultrasonic pest repellents are added in all directions, it will also cause problems such as increased cost. Summary of the Utility Model
