Embodiment Construction

[0033] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the unmanned helicopter 1 includes a body frame, and the body frame is equipped with a rotor flight system and a landing gear assembly controlled by the flight control host. The unmanned helicopter 1 is equipped with a pesticide application device for pesticide application. The pesticide application device includes a medicine box 3, a liquid pump 2, a foldable spray boom 4 and a centrifugal nozzle 5. The medicine box 3 is an integral streamlined structure, which is installed in the lower middle part of the body frame, and matches the streamlined shape of the unmanned helicopter's exterior structure to reduce air resistance; the medicine box 3 is equipped with a shockproof plate, which separates the inner cavity of the medicine box Two interconnected chambers are formed to slow down the fluctuation of the liquid medicine in the medicine tank caused by the flight of the aircraft, so as to ensure the safety...

Abstract

The invention provides an intelligent pesticide application unmanned helicopter and belongs to the technical field of agriculture. The unmanned helicopter comprises a helicopter body frame, wherein the helicopter body frame is provided with a rotary wing flight system and a undercarriage component which are controlled by a flight control main engine; the communication end of the flight control main engine is communicated with a global position system (GPS), the master control output end of the flight control main engine is connected with the controlled end of the rotary wing flight system and is used for sending a navigation control signal to the flight system according to a contemplated route and real-time position information transmitted from the GPS; the central part below the helicopter body frame is also provided with a pesticide application device consisting of a pesticide chest, a liquid pump, a spray beam and a spray nozzle; the liquid outlet of the pesticide chest is communicated with the spray beam with the spray nozzle through a liquid infusion pipeline and the liquid pump; the flight control main engine also comprises an auxiliary control output end; and the auxiliary control output end is connected with the controlled end of the liquid pump and is used for sending a pesticide application control signal to the liquid pump according to the preset pesticide application sites and the real-time position information transmitted from the GPS. The unmanned helicopter can realize automatic navigation flight and can automatically control the pesticide application operation.

Description

technical field [0001] The invention relates to an unmanned helicopter, in particular to an intelligent pesticide application unmanned helicopter, which belongs to the field of agricultural technology. Background technique [0002] Compared with traditional manual pesticide application in the field, aerial spraying has high operating efficiency, zero harm to operators, greatly reduced labor and labor intensity, less fog drop drift, strong penetration of fog flow to crops, and good control effect. Significant advantages such as significant improvement, especially helicopter spraying, no need for special take-off and landing airports, good maneuverability, so it provides an ideal operating platform for rapid and effective prevention and control of paddy field outbreaks of diseases, insect pests and weeds, and promotion of large-scale rice plant protection technology upgrades. [0003] At present, aerial spraying is widely used in developed countries such as the United States a...
