Spraying systems and plant protection drones

Abstract

A spraying system and a plant protection drone, the plant protection drone comprises a fuselage, a nose, and a plurality of arms (16) connected to the fuselage, and the spraying system comprises a liquid storage tank (10) and a water divider (12) , the water pump (13), the liquid pipe (14) and the nozzle (15), the liquid outlet of the liquid storage tank (10) is connected to a plurality of water pumps (13) through the water distributor (12), and the outlet of each water pump (13) The nozzles are connected to several nozzles (15) through liquid pipes (14), and several nozzles (15) connected to the same water pump (13) are all located on the same side arm (16) or on the same arm (16). The spraying system can effectively improve the spraying width and the spraying flow of the whole machine, and can realize the calibration and adjustment of the spraying flow of the single-side nozzle of the spraying system, thereby improving the spraying accuracy and spraying uniformity, and realizing the precise spraying operation of the plant protection drone. need.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, and more particularly, to a spraying system and a plant protection unmanned aerial vehicle. Background technique [0002] In recent years, drone plant protection operations have been welcomed by the public and developed rapidly due to their high operating efficiency, good terrain adaptability, low water consumption, low operating costs, and easy transition operations. One of the most core systems is the spraying system. Due to the limited flight time of drones, the demand for operational efficiency and large flow is more and more urgent. To improve operational efficiency, it is necessary to increase the spray width and the spray flow of the whole machine. At the same time, there is also a very important point. During the operation of the plant protection drone, there are high requirements for the accuracy of the spray flow of the nozzles on both sides of the fuselage. It must be as...

At the same time, there is also a very important point. During the operation of the plant protection drone, there are high requirements for the spraying flow accuracy of the nozzles on both sides of the fuselage. Get an even amount of spray

However, the existing spraying system usually cannot individually adjust the difference in the spraying flow rate of the nozzles on both sides of the fuselage, resulting in poor control accuracy of the spraying flow rate of the nozzles on both sides of the fuselage, which cannot meet the needs of precise operations. If the existing spraying system deviates, Calibration cannot be performed, and it may even cause adverse effects on the work.
