Abstract

The smoke generator used in the field of plant protection features a small particle size of the sprayed smoke, which can be diffused with the airflow and has excellent penetration and adhesion. Its dosage is small, so is the pollution. It is safe, labor-saving and highly efficient. This paper has first proposed the use of plant protection UAVs for smoke spraying, a new technology that has turned over a new leaf over plant protection UAV research and can provide theoretical basis for related research. A plant protection UAV smoke spraying device has been developed, consisting of the smoke tank, combustion chamber, fan, igniter, and controller. It utilizes pesticide burning to generate smoke, and sprays it to the plant canopy under the action of the fan and rotor airflow. It features a simple structure, safe and reliable operation, low energy consumption, high working efficiency and easy operation, thus presenting a broad application prospect. SolidWorks software is applied for structural design and smoke fluid analysis, concluding that the structural design is reasonable and the smoke flows evenly in the smoke tank and can generates even smoke. The plant protection UAV smoke spraying device manufactured based on this design has been proven in the experiments on disease and pest control in hickory forest to have good diffusion and penetrability in the plant canopy and to be evenly distributed on all parts of the pant, thus generating a good prevention and control effect.
