AI Technical Summary
When existing drone spraying devices decelerate, turn, or take off and land, the liquid in the liquid tank shakes violently due to inertia, creating a water hammer effect. This causes the drone's center of gravity to shift, its flight attitude to vibrate violently, and it may even lose control and crash. In addition, the liquid is sprayed unevenly, which affects crop growth and economic benefits.
A pesticide spraying device for crop cultivation was designed. By installing a pesticide tank on the drone body, an electric push rod drives the piston plate to move up and down. Combined with an eccentric turntable and flow components, the device achieves stable squeezing and injection of pesticide liquid, avoids the inertia of pesticide liquid affecting flight, and enhances the fluidity and concentration uniformity of pesticide liquid.
It effectively prevents drone flight instability caused by pesticide inertia, ensures uniform spraying of pesticides, improves spraying effect, avoids pesticide sedimentation, and improves crop growth quality and economic benefits.
