The spraying drone is actually a plant protection drone, and the spraying drone is just a popular name, which is a kind name that farmers give to the drone that can spray pesticides.
The professional name of spraying drone is called plant protection drone. As the name implies, it is an unmanned aircraft used for agricultural and forestry plant protection operations.This type of unmanned aircraft is composed of three parts： flying platform (fixed wing, helicopter, multicopter), navigation flight control, and spraying mechanism.It realizes spraying operations through ground remote control or navigation flight control, and then protects agricultural and forestry plants.
A drug spraying drone usually consists of the following main components:
Fuselage: The fuselage is the main structure of the UAV, including wings, fuselage, empennage and other parts. The fuselage is usually designed with lightweight materials, such as carbon fiber composites, to improve the flight performance and stability of the drone.
Power system: Spraying drones usually use electric propellers or jet engines as power systems. Electric propeller drones have the advantages of low noise, low emissions, and simple maintenance, and are suitable for small-scale farmland; while jet-engine drones are suitable for large-scale farmland, with longer flight time and greater load capacity.
Pesticide spraying system: The pesticide spraying drone is equipped with a pesticide spraying system, including sprayers, spray pumps and spray control systems. The sprayer sprays by spraying pesticide solutions or granules, the spray pump provides the pressure required for spraying, and the spraying control system is responsible for controlling the spraying time, dosage and spraying pattern.
Navigation and remote control system: The spraying drone is positioned and navigated through the Global Positioning System (GPS) and inertial navigation system to ensure the accuracy and stability of the flight path. The remote control system allows the operator to remotely control the drone from the ground and monitor the flight status and mission progress.
In this process, the spraying drone is just a tool, a tool that can improve work efficiency, and the degree of operation automation is high. But it is not just a tool, because in the process of pesticide spraying by drones, there are many factors that affect the effect of pesticide spraying. If these factors are not resolved, the spraying effect will be very poor, or Injury occurs.
At present, there are still many problems in the use of plant protection drones, such as:
1. There are very few spraying drones that can really be used for plant protection. It is not a plant protection drone that can fly and spray pesticides. If many technical difficulties are not overcome, the purpose of plant protection will not be achieved at all.
2. The training and after-sales service are not in place, and no one dares to fly the buyer, which is regarded as a decoration.
3. There is a shortage of special anti-flying agents for plant protection drones, farmers lack knowledge of pesticides, and there are many cases of blind blending of agents by individuals, which is prone to problems such as excessive pesticide residues and poor pest control effects.
4. It is difficult to formulate industry standards and apply for machine purchase subsidies.
