Abstract

The invention discloses a novel multi-rotor-wing glide vehicle plant protection machine which comprises an glide vehicle body main body, rotor wings, motors and an automatic flight director, and the novel multi-rotor-wing glide vehicle plant protection machine is characterized in that the structure of the glide vehicle body main body is in an intersect-parallel shape or in a two-rectangle combined type; high-power direct-current brushless motors are respectively assembled on eight outer endpoints of the intersect-parallel shape or the two-rectangle combined type; the rotor wing is assembled on an output rotating shaft of each motor; the automatic flight director is arranged in the middle of the glide vehicle body main body in the intersect-parallel shape or in the two-rectangle combined type through a connecting piece. The novel multi-rotor-wing glide vehicle plant protection machine is safe and stable in flight, simple in structure, fewer in faults, simple and convenient to operate, convenient to maintain, light in weight, accurate in control, low in meteorological condition requirements and low in construction cost and contributes to large-area popularization and application.

Description

Novel multi-rotor aerocraft fog machine

Technical field

The invention belongs to a kind of pesticide spraying device, particularly one is novel multi-rotor aerocraft fog machine.

Background technology

Emerging driverless operation plant protection aircraft in recent years, rely on its reliable and stable flight, win approval widely, but original aircraft main body is provided with circular central plate 8(sees Fig. 4), assembling flight instrument on circular central plate 8, the periphery of circular central plate connects eight rotor connecting arms 9 of dispersion shape, the outer end assembling rotor 1 of rotor connecting arm 9.Complex structure, parts are many, and fastener is many, trouble point is many, plate centered by load-carrying part, this is very large on strength of aircraft impact, requires center plate intensity higher, simultaneously, because such structure is cantilever design, its arm roots is stressed is 6 times of arm tip, its loading characteristic: 6 times of the vibration meetings that produce at the motor of cantilever tip be transmitted to cantilever root, cause flight instrument fly control gyroscope and too frequently calculate, revise flight attitude coefficient, make fly to control gyrosystem error or crash.Simultaneously because conventional confguration aircraft is in the time flying, there is the motor of 4 rotor connecting arms in 45 degree positions, so, under any state of flight, have 4 rotor connecting arms to have twisting resistance to exist, this torsion affects less for little load carrying airplane, but just need to deal with such torsion with more sturdy material for heavy－duty aircraft, overall aircraft cost increases a lot, and the most fatal is the increase of weight in addition.

Summary of the invention

The object of this invention is to provide a kind of novel multi-rotor aerocraft fog machine, flight safety is steady, simple in structure, and fault is few, operates simple and easyly, easy to maintenance, lightweight, controls precisely, and meteorological conditions requires low, cheap, is conducive to spread practicality.

Technical scheme provided by the invention is as follows: comprise airframe main body, rotor, motor and the instrument that automatically flies, it is characterized in that: fuselage agent structure is that intersecting parallels or two rectangles are combined, outside intersecting parallels or combined eight of two rectangles, on end points, assemble respectively high power DC brushless motor, on the output revolving shaft of each motor, assemble rotor; In the middle of the combined fuselage main body of intersecting parallels or two rectangles by the attaching parts instrument that automatically flies.

Good effect of the present invention: 1, " well " font or the combined frame of two rectangles, its arm of force is 1/3rd of the scatter-type arm of force, with respect to scattering frame, this aircraft is applicable to doing heavy－duty flight, simultaneously because its usable area increases greatly, make the motor oscillating of arm point reduce to the numerical value being perfectly safe, have a smooth flight, can not affect gyrostatic normal calculating and running.2, under extreme low-altitude state, there is twisting resistance without any a motor arm, simultaneously because it is simple in structure, trouble point is few, go wrong if operate indivedual motors in simple and easy, easy to maintenance, failure rate is low, real work, available quick-replaceable.3, lightweight, California bearing ratio reaches 1:200.4, adopt autopilot, can identify accurately rapidly flight attitude, can realize automatic takeoff, landing automatically, around a flight, gives directions flight, airline operation, control more accurate, conversion mutually in flight course.Simultaneously send adjustment signal with the frequency of 500HZ, make the outdoor unremitting flight that aircraft can be below strong breeze.Meteorological conditions requires low, and fly-30-+50 degree Celsius can be flown.5, complete machine is cheap, is applicable to doing " fool " type remotely pilotless agricultural spraying machine of common peasant household, is conducive to spread practicality.

Fig. 2 is the birds-eye view of Fig. 1.

Fig. 3 is that fuselage agent structure is the combined schematic diagram of two rectangles.

Fig. 4 is original Aircraft Main body structure schematic diagram.

The specific embodiment

See Fig. 1-3, fuselage agent structure 3 is intersecting parallels for carbon fiber pipe assembles or two rectangles are combined, outside intersecting parallels or combined eight of two rectangles, on end points, assembles respectively high power DC brushless motor 2, assembles rotor 1 on the output revolving shaft of each motor 2; In the middle of the combined fuselage main body of intersecting parallels or two rectangles, assemble flight instrument 7 and battery case 6 automatically by attaching parts, each motor 2 connects the control interface of flight instrument 7 automatically, automatically flight instrument 7 adopts existing commercially available existing product and technology, and it is by ground remote controller control.Chemical spraying device 4 and alighting gear 5 are set below fuselage main body.
