Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0017] Such as Figures 1 to 2 This unmanned helicopter for agriculture, forestry and plant protection with a large load capacity of the present invention includes a frame 1, a transmission system, a rotor system, a power plant, a fuel system, a landing gear 2, a fairing 3, a flight control system 4, a data chain system 5, sprinkler system and ground control system 6. Landing gear 2 is a skid structure, which increases the safety of helicopter take-off and landing. The transmission system, rotor system, power plant, fuel system, landing gear 2, fairing 3, flight control system 4 and spraying system are all arranged on the frame 1, and the fairing 3 is wrapped in the frame 1, the fairing 3 makes the unmanned helicopter have certain concealment. Described power unit is a pist...

Abstract

The invention discloses an agricultural and forestal plant protection unmanned helicopter with large load capacity. The agricultural and forestal plant protection unmanned helicopter with large load capacity comprises a rack, a transmission system, a rotor wing system, a power device, a fuel oil system, an undercarriage, a fairing, a flight control system, a data chain system, a spraying system and a ground control system. The transmission system, the rotor wing system, the power device, the fuel oil system, the undercarriage, the fairing, the flight control system and the spraying system are arranged on the rack, and the fairing wraps the rack. The spraying system comprises a U-shaped pesticide box and a spraying rod, and the U-shaped pesticide box guides liquid pesticide into the spraying rod through a water pump of a gasoline engine. According to the scheme, a manned helicopter is used as a prototype and is structurally improved, the characteristic that the manned helicopter is large in load capacity is retained, the agricultural and forestal plant protection unmanned helicopter can be provided with the high-capacity U-shaped pesticide box, and therefore, the working efficiency of spraying operation of the helicopter is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural spraying unmanned helicopters, and in particular relates to an unmanned helicopter for agriculture, forestry and plant protection with a large load capacity. Background technique [0002] my country is the most populous agricultural country in the world, with 1.8 billion mu of basic farmland and vast forests, requiring a large number of agricultural and forestry plant protection operations every year. The number of people poisoned by pesticides in my country is as high as 100,000 every year, and the fatality rate is about 20%. Although there is no official statistics on the number of deaths caused by pesticide residues and pollution, it should be an alarming number. [0003] Therefore, the demand for agricultural and forestry plant protection UAVs in China is quite huge. Agricultural and forestry plant protection UAVs have the advantages of high efficiency and safety, autonomous or remote c...
