Abstract

Powder spraying has unique strength in plant pest prevention and control. This article has first proposed the application of plant protection UAVs for powder spraying, to utilize advantages of powder to improve the control effect. It has designed a plant protection UAV powder spraying device, consisting of the pesticide tank, powder blowing pipe, air pump, fan and controller, put forward the working principle of the powder spraying device using the air pump, fan and rotor to work together to achieve air flow powder transport, pneumatic powder spraying and rotor wind transport. SW software has been employed to complete the structural design and fluid analysis of pesticide powder, indicating the reasonable structural design, proven by the powder spraying and even powder flow. The plant protection UAV powder spraying device manufactured based on this design features a simple structure, convenient operation and high working efficiency. The experimental results in the pest control in the hickory forest show that the pesticide spreads well in the plant canopy and penetrates evenly in all parts of the plant, thus to produce a good control effect. This device has high promotion value in UAV plant protection, especially for fruit tree plant protection.
