Abstract
The invention relates to the structural design field of aircraft auxiliary devices, particularly to a feeding box of an agricultural aviation aircraft. The feeding box of the agricultural aviation aircraft comprises a box body which is of a fiber reinforced plastic sandwich structure; an inner layer and an outer layer of the fiber reinforced plastic sandwich structure are glass cloth layers; a middle layer of the fiber reinforced plastic sandwich structure is a foamed plastic sandwich layer. According to the feeding box of the agricultural aviation aircraft, the box body is of the fiber reinforced plastic sandwich structure and accordingly the high pressure can be born, the weight is light, the acid and alkali corrosion resistance is good, the maintenance cost is low, and the service life is long.
Description
Technical field
The present invention relates to aircraft additional device structure design field, specifically, relate to a kind of agriculture boat aircraft hopper.
Background technology
Along with the popularization day by day of General Aviation agricultural aircraft aviation operation, a kind ofly both met agriculture boat spraying operation demand, the agriculture boat hopper that meets again aircraft agricultural equipment system feature becomes agriculture boat equipment research emphasis.Domestic existing agriculture boat hopper has two kinds of all-metal and metallic frameworks, and is all installed in aircraft cabin, and not only weight is heavier, has also additionally taken in a large number carry-on finite space.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality needs, a kind of agriculture boat aircraft hopper is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
An agriculture boat aircraft hopper, comprises casing, and described casing adopts frp sandwich construction, and the ectonexine of described frp sandwich construction is glass woven fabric laying, and interlayer is plastic foam sandwich structured layer.
Described casing top is upper wall, and described upper wall is provided with top-feed lid, and described casing rear portion is provided with rear portion filling opening.
The shape of described casing upper wall and aircraft configuration shape face match and substitute the part of aircaft configuration covering.
Also be provided with breather pipe, one end of described breather pipe is communicated with box house, and the other end is communicated with atmosphere.
In described casing, be provided with anti-sloshing baffles, the diaphragm structure that described anti-sloshing baffles is horizontally set, is covered with honeycomb hole on the wooden partition of dividing plate.
Beneficial effect of the present invention is:
1. casing adopts frp sandwich construction, can bear elevated pressures, and quality is light, acid-alkali-corrosive-resisting, and maintenance cost is low, long service life;
2. the design of two charge doors realizes the aircraft dosing of not stopping;
3. upper wall is pressed aircraft Design of Aerodynamic Configuration, replaces a part for aircraft skin, reduces aircraft resistance and structural weight;
4. built-in breather pipe, prevents generation negative pressure in hopper;
5. liquid, solid (particulate matter) are general, can integral disassembly, assembly, and version is simple, and opening is unobstructed, and clean and maintenance is convenient
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: referring to Fig. 1.
An agriculture boat aircraft hopper, comprises casing 2, and described casing adopts frp sandwich construction, and the ectonexine of described frp sandwich construction is glass woven fabric laying 7, and interlayer is plastic foam sandwich structured layer 8.This version intensity is high, and good rigidly, is applicable to large-size components, glass woven fabric material, the number of plies, and the choose reasonable of foamed plastic sandwich material, density, thickness and glue can meet the actual demand of agriculture aircraft aviation operation hopper.This design can meet the requirements such as aviation liquid container pressure test, and the hopper of relative all-metal or metal framework structure can reduce the structural weight of 50-100%.Glass-felt plastic non-metallic material has good decay resistance, long service life, and the various agricultural chemicals of applicable agriculture boat operation etc. spray the operating needs of carrier.The various repairing characteristics of glass-reinforced plastic material are applicable to this glass-felt plastic agriculture boat hopper, greatly reduce maintenance time and cost, indirectly improve aircraft operation benefit.
Casing top is upper wall 10, and described upper wall 10 is provided with top-feed lid 11, and described casing 2 rear portions are provided with rear portion filling opening 4.Top-feed lid 11 can be hopper provides liquid and solid (particulate matter) reinforced passage, and rear portion filling opening 4 makes liquid feeding passage away from properller, can implement at aircraft rear portion the aircraft floor liquid feeding that do not stop.
The shape of described casing upper wall 10 and aircraft configuration shape face match and substitute the part of aircaft configuration covering.Agriculture boat aircraft hopper is the airborne tankage of large scale, for rationally utilizing the finite space on aircraft and reducing aircaft configuration weight, upper wall 10 is designed to aircraft configuration shape face, substitutes aircaft configuration covering, is a kind of rationally efficient enforcement approach.
Also be provided with breather pipe 1, one end of described breather pipe 1 and casing 2 internal communication, the other end is communicated with atmosphere, and the negative pressure while preventing agriculture boat operation and jury launch in hopper produces.
In described casing, be provided with anti-sloshing baffles 12, the diaphragm structure that described anti-sloshing baffles 12 is horizontally set, is covered with honeycomb hole on the wooden partition of dividing plate, has met the requirement of large-scale liquid container to liquid anti-shake.Box house adopts large radian corner, and the design of each bevel angle meets object and stack angle of repose requirement, while making hopper loading solid material, can not produce the residual phenomenas such as bridging.
On rear portion filling opening 4 sides, be also provided with observation window 3, can Real Time Observation reinforced according to the situation control of material in casing.Hopper bottom is furnished with rustproof aluminum alloy lower flange 6, for hopper jury launch device or other equipment connections.Hopper can, by strengthening the bolt assembly at pad 9,5 places before and after dismounting, to hopper integral disassembly, assembly, be convenient to casing and safeguard.
The invention of glass-felt plastic agriculture of the present invention boat medicine-chest, has improved the system effectiveness of aircraft agricultural equipment, saves agriculture boat aircraft operation cost, and improving agriculture boat operational benefit, also to fill up domestic correlation technique blank.
