[0002] In pesticide spraying operations, the efficiency and value of drones have gradually been recognized. Studies have shown that agricultural drones can save 90% of water and 30%-50% of pesticide usage, and are 40 to 60 times more efficient than manual labor and 5 times more efficient than tractors. A small drone with a payload of 8-10 kg of pesticide can complete one acre of spraying operations per minute.

[0003] Chinese patent CN209506092U proposes a spraying device for a pesticide spraying drone, including a drone body, a medicine storage box and a spray pump. An auxiliary wheel is fixedly installed at the end of the support frame, and a proximity sensor is fixedly installed on the support frame corresponding to the auxiliary wheel through a rubber bracket. The output end of the proximity sensor is electrically connected to the input end of the PLC processor inside the drone body, and a fan-shaped nozzle is spirally installed at the end of the spray rod through a spiral port. The spraying device of the pesticide spraying drone has the advantages of uniform spraying of pesticides during spraying, avoiding waste of drugs, and effectively avoiding the drone from falling when it hits crops or buildings, affecting the efficiency of spraying pesticides. It solves the problem that the existing drone sprays pesticides by using the four corners of the bottom of the drone to spray farmland, which is easy to cause repeated spraying of farmland, waste of drugs, and the drone hits crops or buildings during flight, reducing the spraying efficiency of pesticides. However, the above scheme cannot reduce the buffering force of the operating drone during landing, which easily causes the operating drone to be damaged by collision and internal parts, reducing the service life of the operating drone.
