Problems solved by technology

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.

Embodiment 1

[0026] like Figure 1 to Figure 4 As shown, a flow meter 11 is provided between the liquid outlet of the liquid storage tank 10 and the water separator 12, and the flow meter 11 detects the actual flow rate flowing through the water pump 13 when a single water pump 13 is turned on, so as to determine the reference flow rate and The actual flow is compared to calibrate the output flow of the water pump 13 .

[0027] Specifically, before the plant protection drone performs the spraying operation, the flowmeter 11 is used to calibrate the output flow of each water pump 13 of the spraying system to ensure that the spraying flow of the nozzles on both sides of the spraying system is consistent. During the specific calibration operation, One of the water pumps 13 can be turned on separately, and the actual flow through the water pump 13 can be detected by the flow meter 11, and then the reference flow input by the user and the actual flow actually detected by the flow meter 11 are c...

Embodiment 2

[0034] A flow meter 11 is provided at the water inlet pipe, water inlet, water outlet or water outlet pipe position of each water pump 13, and the flow meter 11 detects the actual flow rate flowing through the corresponding water pump 13 when the water pump 13 is turned on, so as to determine the reference input by the user. The flow is compared with the actual flow to calibrate the output flow of the water pump 13 .

[0035]Specifically, before the plant protection drone performs the spraying operation, the flowmeter 11 is used to calibrate the output flow of each water pump 13 of the spraying system to ensure that the spraying flow of the nozzles on both sides is consistent during the spraying operation. During the specific calibration operation, The actual flow through the corresponding water pump 13 can be detected by the flow meter 11, and then the reference flow input by the user is compared with the actual flow actually detected by the flow meter 11. If the difference be...

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...
