Agricultural spraying uav are essential tools for agricultural plant protection and must be regularly maintained or overhauled. The timely maintenance of agricultural spraying drones can reduce the various hazards caused by pesticide residues and maximize the service life of drones.

1. Agricultural spraying uav machine cleaning
Cycle: The agricultural spraying uav must be cleaned every day during the operation, and it can be cleaned once a week during the non-operation period.
Cleaning precautions: mainly clean wet towels for the machine, wipe the outer surface of the fuselage such as the propeller, medicine box surface and arm, do not rinse directly with running water, and then wipe clean with a dry rag to store.
2. Agricultural spraying drone inspection spraying system
Agricultural spraying uav chemical liquid direct contact spraying system, including medicine box, pipeline, diaphragm pump, spray head, nozzle, flowmeter, etc. Pesticide belongs to chemical agents that have certain corrosion characteristics to metals and plastics. Use clean water to spray the liquid medicine in the system until clean water flows out. Brush the nozzle with clean water in the clean water. If spraying the adsorbed herbicides and growth regulators, soak and repeat cleaning with detergent in warm water. Check and replace the nozzle regularly And flow meter.
3. Maintenance of agricultural spraying uav power system

The main smart batteries, plugs, motors and other components of agricultural spraying uav. The incorrect use of smart batteries during charging and storage will affect their life. Generally, the charging current of smart batteries is between 1C and 2C, and there is no emergency. Under the circumstances, it is recommended to charge with a small current. In addition, charging and discharging under high temperature conditions can easily cause battery bulging. The loss of smart battery storage has a significant adverse effect on its life. The long-term storage capacity is maintained between 50% and 60%, each three Charge and discharge once a month.
