PURPOSE: A manless spraying helicopter for agriculture is provided to reduce the number of workers and the time by spraying dusting powders with a helicopter wirelessly driven. CONSTITUTION: A manless spraying helicopter for agriculture comprises a body(10), outriggers(20), a driving part, a spraying part, a dust powder storing part, a receiving part(60), a control part, and a power part. The body has a circular section in a lateral direction. The outriggers are received in the body. When the outriggers are placed on the ground, the outriggers are unfolded from the body. The driving part comprises an electric motor, a rotary shaft(33), and coaxial contra-rotating rotors(35). The rotary shaft is installed in one end of the electric motor and is extended to the top of the body. The same axial contra-rotating rotors are installed in the rotary shaft to generate buoyancy. The spraying part comprises a spraying and pressing shaft, a piston, and a cylinder. The receiving part wirelessly receives control signals from a remote controller. The control part controls the outriggers and the driving part based on the control signals receiving from the receiving part. |
