Abstract:
Provided are a spray system and an unmanned aerial vehicle for crop protection. The unmanned aerial vehicle for crop protection comprises a body, a nose, and a plurality of arms (16) connected to the body. The spray system comprises a liquid storage tank (10), a water separator (12), water pumps (13), a liquid tube (14), and nozzles (15). A liquid outlet of the liquid storage tank (10) is connected to the water pumps (13) by means of the water separator (12). The water outlet of each of the water pumps (13) is connected to a portion of the nozzles (15). Part of the nozzles (15) connected to a same water pump (13) are all provided at arms (16) at the same side or on a single arm (16). The spray system effectively increases spray width and spray flow volume of the vehicle overall, and calibrates and adjusts the spray flow volume of nozzles arranged at a single side of the spray system. Spraying accuracy and uniformity are thus improved, thereby meeting requirements for accurate spray operations employing an unmanned aerial vehicle for crop protection.
