Concrete condition understands concrete meaning of the above-mentioned term in the invention.
In order to solve the technical issues of plant protection drone rotor 3 existing in the prior art is easily damaged, the present embodiment is mentioned
For a kind of plant protection drone of anticollision as shown in Figure 1 and Figure 2, including rotor platform 1,1 edge of rotor platform is evenly distributed with
Multiple rotor arms 2,2 end of rotor arm are provided with rotor 3, and rotor 3 is driven by flight motor 4 to be rotated, wherein on rotor platform 1
Multiple dampening assemblies 5 are evenly distributed with, dampening assembly 5 is connect with rotor arm 2.
Dampening assembly 5 is provided with one for for rotor arm 2 on one side on shell 12 as shown in figure 4, including a shell 12
The through-hole 11 of one end insertion, rotor arm 2 be inserted into it is arranged symmetrically on two opposite sides of one end inside shell 12 there are two
Pulley；Be symmetrical arranged in shell 12 there are two buffer stopper 10, two opposite sides of buffer stopper 10 are disposed as inclined-plane, pulley with
Contact of incline plane is simultaneously slided along inclined-plane；10 upper and lower ends of buffer stopper are slidably connected with 12 inner top wall of shell, bottom wall respectively；Two
It is provided with the first spring 13 between 12 internal side wall of buffer stopper 10 and shell, is set between 12 bottom walls in linking arm bottom end and shell
It is equipped with second spring 14；
2 other end of rotor arm runs through the side wall of a protective shell 8 and is fixedly connected with 8 inner wall of protective shell, the upper surface of protective shell 8
It is separately installed with ventilative anticollision lid 9 with lower end surface, the space that protective shell 8 and upper and lower two anticollision lids 9 are formed is for accommodating rotation
The wing 3；It is hinged with support rod 6 below rotor platform 1, is hinged with electric pushrod 7 on underlying 9 bottom surface of anticollision lid, it is electronic to push away
7 bottom end of bar and 6 middle part of support rod are hinged.
One end that above-mentioned telescopic rod is connect with rotor 3 is extended to be fixedly connected with 8 inner wall of protective shell, which is prolonged
Length is protective shell 8 and telescopic rod has two fixed connection, i.e., the two-end-point of one diameter can make protective shell 8 more steady in this way
Gu being connected between the protective shell 8 and anticollision lid 9 by existing connection type, such as buckle, threaded connection etc..
Above-mentioned unmanned plane at work, since protective shell 8 and upper and lower two protection caps are protected, the plant branch in flight course
It is normal that rotor 3 is effectively protected in the case where leaf will not protrude within the scope of 3 radius of turn of rotor, not will cause 3 stuck damage of rotor
Rotation, enables unmanned plane to work normally.
During unmanned plane during flying, when colliding, rotor arm 2 is to 8 internal motion of shell, and pulley 15 is along buffer stopper
Inclined-plane sliding on 10, since the distance between two pulleys 15 are constant, but the distance between two inclined-planes are variation, institute
With in 15 sliding process of pulley, two buffer stoppers 10 are moved to both sides, at this point, in the bullet of the first spring 13 and second spring 14
Under power effect, buffer stopper 10 can be stopped mobile, that is, counteract the active force that collision generates and reduced to reach damping effect
Power suffered by rotor arm 2 achievees the purpose that protect rotor 3 and rotor arm 2.
The hinged support rod 6 in 1 lower section of rotor platform can control it to pack up and put down, such as Fig. 1, figure by electric pushrod 7
Shown in 3, compared to most of unmanned plane undercarriages, structure is simpler, and commercially available common product is used only in electric pushrod 7
, convenient maintenance and replacement, while reducing unmanned plane overall cost.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
