Application analysis of hydraulic nozzle and rotary atomization sprayer on plant protection UAV

Abstract

Plant Protection Unmanned Aerial Vehicle(UAV) is the most representative technological product in the construction of precision agriculture in recent years. From direct seeding to areal plant protection, UAV is playing an irreplaceable role. InJapanandChina, UAV plant protection has been adopted by more than 4 million farmers in the past    5 years. The sprayer, as an executive component of the plant protection UAV has also made great progress in the past few years. At present, the sprayers being widely used on UAV platforms are Hydraulic Nozzles and Rotary Atomization Sprayers. This article will detail the two popular sprayers and compare them in field applications. The results showed that the rotary atomization sprayer is more suitable for low-volume and variable-rate spraying, both are not possible by hydraulic nozzles. Since variable spraying is an important functionality for precision agriculture, rotary atomization sprayer will be the direction for future UAV and robot sprayer design.
