According to the utility model, described agricultural machinery main body (1) comprises body (8) and is arranged on the medicine liquid spray system (9) on described body; Body (8) and medicine liquid spray system (9) all can use structure known in the art, system and layout.
According to the utility model, the two ends of described collapsible rotor arm (2) are respectively nearly agricultural machinery main body (1) end and rotor end, described rotor end assembles motor and the rotor that promising flight provides power, and nearly agricultural machinery main body (1) end is fixed by socket with the folding head (4) of described fold mechanism (3), the strengthening mechanisms such as such as screw are preferably used to reinforce.
According to the utility model, described folding head (4) is held with the nearly agricultural machinery main body (1) of rotor arm (2) and is fixed by socket, it is fixed on corresponding aperture position flexible connection with it on the baffle plate (5) in agricultural machinery main body (1) in advance by the Kong Weiyu that nearly agricultural machinery main body (1) on it is held, such as, by conventional screw, nut combinations, linkage etc.;
Described folding head (4) and baffle plate (5) have qualifying bit corresponding to shape (10), include but not limited to S shape etc., when rotor arm (2) is in folded state, because of gravity naturally droop time, the engaging of the S shape qualifying bit (10) above preset by folding head (4) and baffle plate (5), realize the fixing of pendant position, in order to avoid rotor arm (2) shakes in transportation, there is unnecessary collision with fuselage miscellaneous part and cause structure and they deteriorate;
According to the utility model, when rotor arm (2) launches, it realizes rotor arm (2) by folding head (4) and the clamping of turn buckle (6) and launches the fixing of attitude.Turn buckle (6) is fixed in agricultural machinery main body (1), centered by rotor arm (2) that can be corresponding, left rotation and right rotation swings, when rotating to time parallel with rotor arm (2), the projection such as can preset with folding head (4) engages and the expansion attitude of rotor arm (2) is fixed.
According to the utility model, when rotor arm (2) launches, itself and agricultural machinery main body (1) horizontal surface are the dihedral angle of 5 degree; Horn dihedral of the prior art normally dihedral angle 7-8 degree, contriver of the present utility model is found by repetition test, by this dihedral is set in specific 5 degree, significantly can increase the stability of aircraft, aircraft configuration also can be made more attractive in appearance; In addition, 5 degree of dihedral angles not only can increase the stability of aircraft, can also cruise duration of significant prolongation aircraft, economize energy.
According to the utility model, the constant intensity under attitude is being launched with agricultural machinery main body (1) in order to increase rotor arm (2), described turn buckle (6) possesses self-locking function, it is realized with the spacing hole (11) be preset on agricultural machinery main body (1) panel by the ripple pearl (7) arranged thereon, when rotating to clamped position, the spacing hole (11) that the bottom surface that ripple pearl (7) stretches out turn buckle (6) downwards because of its elastic reaction enters in agricultural machinery main body (1) is inner, thus realizes self-locking function.This structure design can enter to prevent unmanned plane further in flight course to cause the accident because vibrations make turn buckle be shifted, and makes flight operation more safe and reliable.
According to the utility model, the quantity of described rotor arm (2) is preferably 4, and it distributes around agricultural machinery main body (1) in two rotational symmetry; In addition, fold mechanism of the present utility model (3) each parts all adopt industrial grade metal construction, and be different from the plastic cement structure of prior art, the service life of technical solutions of the utility model increases greatly.
To sum up, relative to other fog machines of prior art, the utility model has the advantage of:
1. collapsible, and folded state is stablized, and is convenient to transport;
2. more stable, the safety of flight;
3. cruise duration is long;
4. greatly extend service life;
5. structure is simple, low cost of manufacture.
