The invention provides a facility agriculture wireless remote control automatic spraying machine which can improve the facility vegetable production labor efficiency and reduce harms of pesticide to human bodies and pollution to the environment. The facility agriculture wireless remote control automatic spraying machine comprises a machine frame, a walking system, a spraying system, a folding frame, a folding cylinder, a telescopic frame, a telescopic cylinder and a wireless remote controller. The walking system comprises a walking motor, a walking gearbox and drive wheels. The spraying system comprises a pesticide box, a spraying pump and spray nozzles. The bottom end of the folding frame is movably connected to the machine frame. The folding cylinder is used for controlling the folding frame to be lifted up or folded. The telescopic frame is arranged on the folding frame. The telescopic cylinder is used for controlling the telescopic frame to be stretched out or drawn back. The wireless remote controller operates the walking system, the folding frame and the telescopic frame to act by sending wireless signals and operates the spraying system to spray pesticide. A controller and a battery are connected to form a serial connection circuit. The controller is connected with the folding cylinder, the telescopic cylinder, the walking motor and the spraying pump, and can receive wireless signals sent by the wireless remote controller.
