Oil-driven bevel-gear differential-speed-type multi-rotor agricultural spraying aircraft

Abstract

An oil-operated bevel gear differential multi-rotor agricultural spraying aircraft relates to the technical field of agricultural unmanned aerial vehicles. The invention can realize the purposes of large load capacity, long flight time, good spraying operation quality, high operation efficiency, low operation cost, eliminating phytotoxicity caused by farmers spraying pesticides, and saving labor force. The engine is fixedly connected with the driving gear of the gear or belt transmission mechanism, and the driven gear of the gear transmission mechanism is fixedly mounted on the horizontal central shaft of the central bevel gear transmission box. The horizontal central shaft and the two central output shafts of the central bevel gear transmission box are both Bevel gear 1 and bevel gear 2 of the bevel gear differential transmission box are fixedly connected with the rotor input shaft of the rotor bevel gear transmission box of the rotor transmission mechanism, and the two rotor output shafts of the rotor bevel gear transmission box are fixedly equipped with Rotor, the worm gear in the worm gear transmission mechanism is installed on the rotor input shaft, and the worm is connected with the speed regulating motor. The invention is used in the fields of agricultural spraying operation, aerial inspection, air transportation and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural unmanned aerial vehicles, in particular to an oil-operated bevel gear differential multi-rotor agricultural spraying aircraft, which belongs to the flying platform used in the field of agricultural production. Background technique [0002] With the vigorous development of agriculture, agricultural production puts forward a higher demand for modern agricultural facilities. The advantages of agricultural aviation operations are becoming more and more significant, and their uses are becoming more and more extensive. Aviation operations can also play an important role in the standardization and intensification of agricultural services, ensuring the efficiency of large-scale land production, monitoring the use of pesticides for farmers, preventing natural disasters and pests, and improving the human living environment and ecological balance. [0003] At present, large state-owned farms such as rec...

AI Technical Summary

Problems solved by technology

[0003] At present, large state-owned farms such as reclamation areas mainly use man-machine spraying operations. For example, Beidahuang General Aviation mainly serves several reclamation areas in the northeast. Man-machine spraying operations are limited by airspace and pilot qualifications, and there are high spraying costs and poor spraying effects. many disadvantages

UAVs suitable for spraying mainly include helicopters and multi-rotors. Helicopter technology is relatively mature, but its mechanical mechanism is complex, high in cost, and poor in stability. Multi-rotor UAVs are stable in flight, flexible in control, and low in cost. At present, multi-rotor drones are mainly powered by batteries. Due to the constraints of battery performance, batteries need to be replaced frequently, with low load, short flight time, long operation time, and low work efficiency.

[0004] There is a four-rotor oil-driven device that uses the principle of a helicopter to combine four helicopter pitch mechanisms. Due to the complex structure of the pitch mechanism itself and poor control flexibility, it is not suitable for agricultural production.
