Agricultural drones spray pesticides mostly in the high temperature and humid environment, and the single operation time is generally long, so the maintenance work of agricultural spraying drones should be paid attention. Look at the maintenance methods of agricultural spraying drones here!
1. The agricultural spraying drones must be cleaned every day during operation, and it can be cleaned once a week during non-operation. As long as the cleaning work is aimed at the main body of the fuselage, such as big paddle, tail paddle, fuselage plate, tail rod, exposed bearing, etc. Gasoline should be used to clean the fire head, and the carbon deposits on the fire head should be brushed off by copper wire brush. After cleaning, measure whether the gap between the fire head is 0.7MM with a tape. Remember not to wash the parts of electronic equipment directly with water to avoid bad contact or damage.
2. In addition to cleaning the agricultural spraying drones, inspection work should also be done. The inspection mainly includes:(1) the fixed condition of each screw of the main rotor, the fixed condition of the big pulp, and whether the T-head is loose;(2) whether there is Sway in the horizontal direction of the main shaft, and whether it is loose up and down;(3) whether the main tail belt is loose or worn;(4) whether the connecting part of the tie rod is loose or deformed, whether the ball nose is worn or not, and the gap size;(5) whether the water pump and nozzle are blocked, whether the line water pipe is oxidized or not;(6) when checking the exposed bearing of the main shaft and the exposed shaft of the tail horizontal shaft, the bearing is suggested to be coated with lubricating oil.
3. Agricultural spraying drones need to be stored during a non-use period. The storage is not just to find a place to store, but to pay attention to the following points: first, the storage place must be waterproof, sunscreen, insect-proof, fire prevention and keep away from places where electric leakage may be formed; Secondly, when storing, pay attention to fixing firmly and ensure that the agricultural spraying drones will not be squeezed by other objects; Thirdly, if the storage time is too long, in order to prevent the deformation of the main rotor, the main rotor can be disassembled and hung; Fourth, when storing the battery and the remote controller, it should be placed in a separate box, paying attention to fire prevention, moisture prevention and anti-riot sun. And put the battery into the storage voltage, and charge it every other month (when it is stored for a long time); Fifth, every active part should be electrified or lubricated every other period of time; Sixth, after storage, supervision work should be done well to prevent others from misoperation and misadjustment.
4, Although careful in the process of using agricultural spraying drones, but can not avoid some small faults, and usually these small faults are mainly caused by the lack of maintenance. For example, after finishing the work for the client, because it was too late or the operator had a lot of things to do, he only cleaned the surface of the unmanned aerial vehicle simply, but did not follow the requirements. Generally, it will not have much impact if unmanned aerial vehicles are not cleaned as required once, but failure is easy to occur if they are not cleaned for many times. For example, the main rotor and the tail rotor margin mechanism are not cleaned and maintained timely after the operation is completed, resulting in pesticide residues that will affect the work of the margin mechanism, increasing the working load of the steering gear and causing serious heating of the steering gear. If this situation occurs, the pesticide residues in the margin mechanism should be cleaned immediately, and the lubricant should be used for cleaning and lubrication, thus the problem is basically solved.
Agricultural spraying drones are expensive, so the life span of unmanned aerial vehicles is also a concern. Generally speaking, the main components of unmanned aerial vehicles can be used for a long time without man-made damage or crash. However, in the process of using agricultural spraying drones, we should adhere to the principle of “three-part use, seven-part maintenance” and pay attention to daily maintenance. Cherish it and its life span will be long, otherwise, its life span will be short.

Key points: This project mainly refers to the cleaning work of the main body of the fuselage, such as the cleaning work of the big paddle, the tail paddle, the fuselage plate, the tail rod and the exposed bearing. The exposed bearing is suggested to be coated with lubricating grease to achieve the purposes of lubrication, rust prevention and corrosion prevention.
During the cleaning process, pay attention to observe the integrity of the big paddle, the tail paddle and the tail rod, whether it expands, whether it is cracked and so on, and whether the fixing screws on the fuselage board are loose and so on.

Cycle: check and confirm every day during the operation period, and check and confirm every week during non-operation period.
Key points: Check whether the front axle of gear box has sway in the horizontal direction. If there is sway, it is recommended to return to the factory for maintenance.
Check the one-way bearing. The normal condition is that the clockwise rotation can only rotate, and the anticlockwise direction will drive the spindle to rotate.
6. Check the shaking quantity of the starting shaft
Cycle: check and confirm every day during the operation period, and check and confirm every week during non-operation period.
Key points: Check whether the starting shaft has obvious sway. If there is sway, it is recommended to return to the factory for maintenance.

Key points: the storage point of the fuselage should pay attention to fire prevention, moisture prevention, dust prevention, dust prevention and sun protection, and keep away from the places that may cause circuit leakage.
It is suggested that the battery and remote controller should be stored in a separate box. The storage point of the box should also pay attention to fire prevention, moisture prevention and anti-riot sun, and be far away from places that may cause electric leakage. The storage of the fuel tank should pay attention to fire prevention, moisture proof, and anti-riot sun, and keep away from places where may cause electric leakage. The fuel tank cannot be stored in the carriage for a long time. If the oil tank is stored with oil, please do not screw the vent to death.

Key points: pay attention to whether there are few teeth, forks and other conditions that may lead to fracture, and check whether the tightness is appropriate.
20. Check and replace the air filter
Cycle: it is recommended to replace it at least once a week during the operation. Working in a relatively harsh environment can shorten the inspection and replacement cycle.
Key points: whether the air filter is clean or not will affect the working efficiency of the engine, so check the air filter frequently; When replacing and installing, pay attention to whether the fixed clamps are aligned and firm.
21. Clean the fire head

22. Inspection and replacement of gear oil
Cycle: it is recommended to check once a week during the operation. After one month of continuous use, you can unscrew the refueling hole to check whether the gear oil is aging. The first flight that has not been used for a long time must also be checked and confirmed. The gear oil should be changed once after the running-in phase of 10 flight hours, and then the gear oil should be changed once every 30 flight hours.
Key points: check the sealing condition of gear oil once a week for leakage. Gear oil aging is obviously recommended to replace.
23. Line inspection
Agricultural spraying drones belong to precision equipment, and any slight changes in components will affect its flight status and service life. Therefore, not only should we be careful in the process of its use, transfer, and storage, but also its daily maintenance work is very important, which even determines its service life to a large extent.
