Body assembly of an agricultural aircraft

Abstract

The invention discloses an agricultural aircraft body assembly. The agricultural aircraft body assembly is characterized in that cantilevers (14) are arranged at the periphery of a device bin (13), wherein a motor bin (15) is arranged at the outer end of each cantilever (14), the device bin (13) is internally divided into a cavity and a liquid medicine cavity by a transverse plate (17), and a chemical feeding pipe (18) is arranged on the device bin (13); two positioning frames (19) are mounted in each cantilever (14), a base plate (20) is fixedly inserted into each two positioning frames (19), and an electronic governor is mounted on each base plate (20); an undercarriage (1) comprises two bottom tubes (3), a support tube (4) is welded to each bottom tube (3), and a support plate (5) is fixed on the top of each support tube (4). The agricultural aircraft body assembly has the beneficial effects that on one hand, the cost can be lowered, the height size of an aircraft can be reduced, and the shaking of a liquid chemical can be prevented; on the other hand, the spaces of the cantilevers can be adequately utilized, and the agricultural aircraft body assembly is good in firmness and stability.

Description

technical field [0001] The invention belongs to the technical field of agricultural aircraft, and in particular relates to an airframe assembly of an 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 landing gear of the existing agricultural quadcopter is supported at the bottom of the fuselage equipment compartment by four quick-change devices. These four quick-change devices have complex structures and high costs, and the positions of the four quick-change devices are relatively concentrated, which will cause the support machine to Body stability is poor.

AI Technical Summary

Problems solved by technology

The landing gear of the existing agricultural quadcopter is supported at the bottom of the fuselage equipment compartment by four quick-change devices. These four quick-change devices have complex structures and high costs, and the positions of the four quick-change devices are relatively concentrated, which will cause the support machine to poor body stability

In addition, the contact surfaces between the four quick-change devices and the fuselage are small, and the reliability of the connection with the fuselage is not good.

Not only that, the medicine box containing the liquid medicine is generally installed under the fuselage, and the medicine box needs to be manufactured separately, which is difficult to process and assemble, and the production cost is high, which will increase the height of the entire aircraft; when there is less liquid medicine in the medicine box, Affected by the working vibration of the aircraft, the liquid medicine will sway, which will affect the balance of the aircraft and reduce the effect of spraying the liquid medicine

In addition, the electronic governor is generally arranged in the equipment compartment. This arrangement not only greatly occupies the space of the equipment compartment, but also affects the arrangement of other components in the equipment compartment; it is also extremely inconvenient to disassemble and assemble, and the performance is not guaranteed.
