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

Abstract

The invention discloses an oil-driven bevel-gear differential-speed-type multi-rotor agricultural spraying aircraft, and relates to the technical field of agricultural-utilization unmanned aerial vehicles. The oil-driven bevel-gear differential-speed-type multi-rotor agricultural spraying aircraft can achieve the purposes that the loading capacity is large, the flight time is long, the quality of spraying operation is good, the operational efficiency is high, the operational cost is low, the chemical injury brought by chemicals spraying by farmers is relieved, and the labor force is saved. An engine is fixedly connected with a gear or a driving gear of a belt transmission mechanism, a driven gear of a gear transmission mechanism is fixedly installed on a horizontal center shaft of a central bevel-gear transmission case, and first bevel gears of a bevel-gear differential-motion transmission case are fixedly installed at the horizontal center shaft and two central output shafts of the central bevel-gear transmission case correspondingly; and a second bevel gear is in transmission connection with a rotor input shaft of a rotor bevel-gear transmission case of a rotor transmission mechanism, rotors are fixedly installed at two rotor output shafts of the rotor bevel-gear transmission case correspondingly, a worm wheel in a worm wheel and worm transmission mechanism is rotatably installed at the rotor input shaft, and a worm is in transmission connection with an adjustable-speed motor. The oil-driven bevel-gear differential-speed-type multi-rotor agricultural spraying aircraft is used in the fields of agricultural spraying operation, air patrol, 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.

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.
