Abstract

People in China always use fixed-wing air crafts until now from aerial seeding in 1956. Flight cost is high, and the fixed-wing air crafts are not suitable for performing operations in mountain and gorge areas. Medium-size helicopter aerial seeding very needs to be developed in China. The utility model provides a built-in seeding device of a medium-size helicopter, and is suited for the performing operation of aerial seeding in plateau areas and particularly in mountain and gorge areas. The utility model is composed of a seed broadcaster and a material box which are combined. The utility model is characterized in that the seed broadcaster is arranged on an outer wall at the abdomen part of a helicopter. The material box is arranged in a helicopter room. The feed inlet of the seed broadcaster and the discharge hole of the material box are butted together and fixedly connected as integration through the openings of an outer hung floor in the helicopter room. The utility model has the advantages that 1. the utility model borrows an FB-85 type air stamping seed broadcaster of a fixed-wing aircraft, does not use any components of a medium-size helicopter, does not drill any holes, and is provided with original connection lugs. The seed broadcaster is successfully arranged at the bottom of the abdomen part of the aircraft. 2. The utility model successfully solves the emergency of large-scale aerial seeding arboriculture of medium-size helicopters in western areas of China, and is suitable for the performing operations of seeding, medicine spreading, fire extinguishing, etc.

Description

The built-in sowing apparatus of Medium Helicopter

Technical field

The utility model relates to the General Aviation field and expand the sowing apparatus that Medium Helicopter is sowed, spread pesticides, stamps out a fire in farming, woods, animal husbandry, exactly is the built-in sowing apparatus that is applicable to that Medium Helicopter uses.

Background technology

World today advanced country is used for the aircraft of scattered seeds by airplane for afforestation, is fixed wing aircraft and helicopter two big classes.Eighties of last century the fifties, the U.S., the former Soviet Union, New Zealand, Japan and other countries extensively adopts the scattered seeds by airplane for afforestation of multiple model helicopter, broadcasts sowing equipment but be light-duty outer suspension type, and carrying capacity is little, the ceiling is low, be not suitable for very much the big mountain area operation of physical features fluctuating.China is since 1956 carry out plant seeds by airplane, continue to use fixed wing aircraft always, only transport five B at present and bear national scattered seeds by airplane for afforestation, have only fortune 12 to be fit to the highlands operations with fortune 12, but flight cost is too high, area, no regular airport such as Ganzi, Aba state particularly, empty flight journey is too far away, the majority economic radius that oversteps the extreme limit, what have broadcasts the district above 350 kilometers, flight cost is too high: relief is too big, and the highest mountain peak, district is most to surpass 300 meters to the actual job flying height apart from broadcasting, and seeding quality more be cannot say for sure to demonstrate,prove; Can't bear Tibet Autonomous Region's plant seeds by airplane task.Because fixed wing aircraft is subjected to airport, air route, the factors such as district's weather, blank pipe of broadcasting restrict too big, particularly in high mountain gorge area operation, flight difficulty height, broadcast sowing required flying height and be difficult to reasons such as assurance, in order to accelerate the paces of western China large-scale afforestation, be badly in need of the plant seeds by airplane of exploitation Medium Helicopter.

Summary of the invention

Goal of the invention of the present utility model is: overcome the problems referred to above that present scattered seeds by airplane for afforestation exists, provide to be suitable in the plateau district, particularly the built-in sowing apparatus of Medium Helicopter of high mountain gorge area plant seeds by airplane operation.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

The built-in sowing apparatus of a kind of Medium Helicopter, combined by dispenser and hopper, it is characterized in that: dispenser is contained on the helicopter belly outer wall, and hopper is contained in the cabin, by the floor opening in the cabin, the seed inlet of dispenser and hopper go out kind of a mouth and dock and connect firmly and be integral.

Additional technical feature is: 1. this sowing apparatus, by the FB-85 type dispenser that is installed on the Medium Helicopter belly outer wall, with be installed in the hopper of hanging opening part in the cabin outside the floor, go out kind of a mouth by existing FB-85 type dispenser seed inlet of this cause for gossip and hopper and dock to connect firmly to be integral and constitute.2. outside engine room floor central authorities, hang opening part, install additional and sow platform, the floor slide rail connects firmly mutually in this platform and the cabin, platform be provided with the floor outside hang relative, the convenient opening that hopper is installed of opening, hopper goes out kind of mouth and docks with the platform seed inlet, the dispenser seed inlet goes out kind of a mouth with hopper and docks by up passing the platform seed inlet under the fuselage, and is connected with the lug of dispenser front portion by the screw rod around the platform openings.3. outside fuselage on the triangular supports of both sides, vertical pull bar to the bottom of fuselage below dispenser is set is connected with transverse channel steels, the lug on the dispenser afterbody is connected with channel-section steel.4. the hopper in the cabin, hypomere is trapezoidal or bullet, its epimere is rectangle or cylindrical body, discharging opening trapezoidal or the bullet lower end connects by dispenser seed inlet under platform seed inlet and the fuselage, on platform, four jiaos at middle part is fixed on by steel cable on the floor, both sides in cabin hopper by the high strength frame fixation.5. the right back floor brake pipe joint adjunction T-pipe joint of getting off the plane in the cabin, its cold air is received pressure reducer by conduit, and the air coolant tube that enters again in manual air cock and the dispenser links, and the protecting material movable lug in the control dispenser opens or closes the discharge chamber door.6. the direct current bus-bar is wired to 20A insurance electric switch on machine, be wired to two master cocies, first master cock is the amount of sowing regulating control in touch block control dispenser, and puddle mixer and electric switch fine setting in second master cock control dispenser realize adjusting and control to the amount of sowing.

Advantage of the present utility model is: 1. successful solution Medium Helicopter be used for farming, woods, animal husbandry and sow, spread pesticides, put out the technical barrier that forest fire does not have suitable sowing apparatus.2. the built-in seeding device of Medium Helicopter of the present invention has been got rid of helicopter at one stroke and has been hung 8 meters flight hidden dangers of being brought.3. also do not have in the world under the situation of the baroque rotary dispenser of the large-scale 2-3 of carrying ton, use the main composition member that fixed wing aircraft air punching press FB-85 type dispenser is made this sowing apparatus, not only saved cost greatly and made operation become simple yet.4. present, the built-in sowing apparatus of device on Medium Helicopter, motivation what parts of taking up an official post not, any eyelet of on machine, not drilling, all install additional along original lug on the machine, and successful is contained in FB-85 type dispenser under the aircraft belly, is the invention of a success, solved the urgent need of the extensive scattered seeds by airplane for afforestation of present western China, become and expanded the breach of Medium Helicopter in farming, woods, animal husbandry field business.5. the utility model sowing apparatus is used for plant seeds by airplane, and is good through the test seeding quality, reaches the quality and technical index of GB regulation fully, and reduced flight cost, can guarantee to finish extensive plant seeds by airplane task in best sowing time, improves plant seeds by airplane efficient.
