Abstract

The invention relates to the field of structural design of aircraft auxiliary components, in particular to a multipurpose agricultural aviation operation door box which comprises a door box casing, wherein a lip-shaped opening is arranged at the upper portion of the casing, a blanking door is arranged at the bottom of the casing, a supporting arm is fixedly connected with the position below the blanking door, one end of the supporting arm is hinged to the bottom of the casing, and the other end of the supporting arm drives the opening or closing of the blanking door through a four-connection-rod control mechanism. The multipurpose agricultural aviation operation door box is suitable for agriculture and forestry agriculture and forestry aircraft agricultural equipment systems, simple and reliable in structure, convenient to maintain, long in service life, and capable of effectively increasing aircraft operation efficiency, reducing usage and maintenance cost, increasing aircraft operation economic benefits and filling up the blank of correlation technique in China.

Description

technical field [0001] The invention relates to the field of structural design of aircraft auxiliary devices, in particular to a multipurpose agricultural aviation operation door box. Background technique [0002] With the increasing promotion of aviation operations of general aviation agricultural and forestry aircraft, higher requirements are put forward for the door box of aircraft agricultural aviation operations. The existing domestic door boxes can no longer meet the requirements of liquid spraying, sowing, and fire extinguishing without disassembly and assembly, and the efficiency of sowing operations is low. [0003] Therefore, need to design a kind of simple in structure, the multifunctional agricultural aviation operation door box of multiple functions. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, meet the actual needs, and provide a multi-purpose agricultural aviation operation door bo...
