Abstract
Provided are a nozzle device for a plant protection unmanned aerial vehicle and a droplet diameter control method thereof. The nozzle device for a plant protection unmanned aerial vehicle includes a flexible nozzle body, a magnetostrictive sleeve, and a coil. The flexible nozzle body is provided with a nozzle exit, a periphery of the flexible nozzle body is provided with a guide surface at a position corresponding to the nozzle exit, the magnetostrictive sleeve is sleeved on the periphery of the flexible nozzle body and abutted against the guide surface. The coil is wound around the periphery of the magnetostrictive sleeve. When the coil is supplied with a current to generate a magnetic field, the magnetostrictive sleeve can move relative to the guide surface, the guide surface squeezes the nozzle exit to deform the nozzle exit, thus adjusting the size of the nozzle exit.
