Agricultural four-axis aircraft

Abstract

The invention discloses an agricultural four-axis aircraft. An equipment bin (15) is located in the middle and is in the shape of a drum, the upper end of the equipment bin (15) is open, the lower end of the equipment bin (15) is closed, and each supporting pipe (14) of an undercarriage (13) is connected with the equipment bin (15) through two fastening pieces; four cantilevers (16) are evenly distributed on the periphery of the equipment bin (15), the inner ends of the cantilevers (16) are integrated with the equipment bin (15), and motor bins (17) are arranged at the outer ends of the cantilevers (16) respectively; motors (31) are arranged in the motor bins (17), and propellers (32) are arranged above the motor bins (17). The agricultural four-axis aircraft is simple in structure, the motors and impellers can be conveniently and quickly disassembled and assembled, the pesticide spraying range is wide, the spraying effect is good, the undercarriage and the aircraft body of the agricultural aircraft can be firmly connected, the undercarriage can be conveniently disassembled and assembled, and a pesticide box can be quickly replaced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a four-axis agricultural aircraft. Background technique [0002] With the development of society and the advancement of science and technology, large-scale spraying of pesticides and fertilization on farmland are gradually completed by unmanned aerial vehicles. The existing agricultural unmanned aerial vehicles are complex in structure, bulky and heavy, which seriously restricts their large-scale popularization and application. for example: [0003] 1) The installation structure of the existing aircraft motor is not only complicated to assemble, time-consuming and labor-intensive, but also takes up a lot of space for the rotor motor, which will increase the height of the entire aircraft; [0004] 2) The installation structure of the propeller is relatively complicated, and the installation process is relatively cumbersome. The installation process is ...

AI Technical Summary

Problems solved by technology

[0003] 1) The installation structure of the existing aircraft motor is not only complicated to assemble, time-consuming and labor-intensive, but also takes up a lot of space for the rotor motor, which will increase the height of the entire aircraft;

[0004] 2) The installation structure of the propeller is relatively complicated, and the installation process is relatively cumbersome. The installation process is time-consuming and laborious, which is not conducive to saving production costs; When it is damaged, the propeller can only be scrapped as a whole, which leads to waste of resources and increases the cost of use;

[0005] 3) The chemical liquid spraying system is not only complex in structure, cumbersome in assembly, large in size, heavy in weight, and high in production costs, but also has a small spraying range, narrow range, uneven spraying, and poor spraying effect; When there is less liquid medicine, the liquid medicine will oscillate due to the vibration of the aircraft, which will affect the balance of the aircraft and reduce the effect of spraying liquid medicine. In addition, the medicine pump is installed on the top of the medicine tank, which will also increase the height dimension;

[0006] 4) The fuselage of the aircraft is not only heavy and bulky, poor in structural strength, easy to damage, but also difficult to process;

[0007] 5) Although the connection structure between the landing gear and the fuselage of the aircraft is relatively reliable, the disassembly operation is cumbersome, and tools must be used, which is time-consuming and laborious; when the agricultural aircraft is in operation, when the liquid medicine in the medicine box is sprayed , it must be refilled through the filling port set on the medicine box before it can work again, which will greatly reduce the operating efficiency of the aircraft
