Abstract
The invention provides a propeller quick-release mechanism. The propeller quick-release mechanism comprises a motor and a propeller which are mounted at the tail end of an aerofoil, wherein the lower part of the propeller is movably connected with a propeller mounting base; arc-shaped clamping grooves with opposite openings are formed in the propeller mounting base; the rotating end of the motor is movably connected with a cuboid-shaped motor mounting base; a retractably connected pressing shaft is arranged on each of the two sides of the motor mounting base; a pin shaft is fixed in the horizontal direction perpendicular to each pressing shaft; a groove adapting to the pressing shafts is formed in the arc-shaped part of each clamping groove; the arc-shaped parts and the pin shafts are in movable limited connection with each other. Through retraction of the pressing shafts, the propeller can be mounted and dismounted, the limit structure is reasonable, the flight demand is met, quick replacement and collection of vulnerable parts are realized conveniently and quickly, and particularly, when the propeller quick-release mechanism is used for mass production and use, low efficiency caused by the reason that professionals and professional tools are not in place is avoided.
Description
Technical field
The present invention relates to plant protection unmanned plane propeller mechanism, be specifically related to screw propeller quick-release mechanism.
Background technology
At present, domestic plant protection unmanned air vehicle technique development rapidly, relies on its efficiency high, flexible operation, adaptable advantage, starts the method progressively substituting artificial spray medicine.Many rotors plant protection unmanned plane is again that in numerous plant protection unmanned plane, quantity is maximum, and it relies on rotor lift to drive medicine-chest to spray, and load carrying ability is easy to greatly control, and is widely used.But as many rotor structures, plant protection process mesorelief is complicated, and rotor itself is fragile, be easy under External Force Acting occur, there will be the situation that rotor damages in actual use unavoidably, in time there is rotor damage or examine and replace, often need the instrument of specialty and personnel to dismantle, maintainability is low.In handling process, irregular due to rotor, not only causes whole body volume huge, and easily loses rotor, cause inconvenience.
Summary of the invention
The present invention is directed to the problem that many rotor wing unmanned aerial vehicles rotor when reality uses damages replacing, transportation dismounting difficulty, provide a kind of installing/dismounting simple, screw propeller quick-release mechanism reliable and stable during use.
The present invention realizes by the following technical solutions, screw propeller quick-release mechanism, comprise the motor and screw propeller that are arranged on wing end, described screw propeller underside connects screw propeller mount pad, screw propeller mount pad is provided with the arc-shaped slot that opening is oppositely arranged, the turning end of described motor is flexibly connected the motor mount of cuboid, the both sides flexible pressing axis connected respectively of mount pad, the horizontal direction of vertical pressing axle is fixed with bearing pin respectively; The curved portions of described draw-in groove is provided with the groove adapted with pressing axis, and curved portions and described bearing pin form the spacing of activity and be connected.
For limiting position further, in the middle part of described screw propeller mount pad and motor mount contact part, be provided with spacing limit shaft and axis hole.
For ease of installing, the side, front and back of described motor mount is provided with the otic placode of screw.
Usefulness of the present invention is; by the flexible Assembly &Disassembly that can realize screw propeller of pressing axis; position limiting structure is reasonable; meet flight needs; realize fast by the replacing of high-mortality parts with pack up, convenient and swift, especially in large-scale production with when using; avoid professional and professional tool is not in place causes inefficiency, the setting of modular universal of the present invention has very high comformability for the screw propeller of various sizes and model.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described,
As shown in Figures 1 to 4, the invention provides a kind of screw propeller quick-release mechanism, it comprises the motor 1 and screw propeller 7 that are arranged on aircraft wing end, and the underside of screw propeller 7 is connected with screw propeller mount pad 6, the arc-shaped slot 61 that the below of screw propeller mount pad 6 establishes opening relative.And the screw that utilizes of motor 1 is fixed with the motor mount 2 of cuboid, both sides are alongst provided with the flexible pressing axis 5 connected, the horizontal direction vertical with pressing axis 5 is respectively equipped with bearing pin 4, the spring 3 of bearing pin 4 in inside is along with the telescopic moving of pressing axis 5.Draw-in groove 61 place of screw propeller mount pad 6 is provided with the groove adapted with pressing axis 5, and such screw propeller mount pad 6 coordinates to contact with motor mount 2 and connects, and the bearing pin 4 in pressing axis 5 forms spacing connection with draw-in groove 61.
In order to make motor mount 2 and screw propeller mount pad 6 position limit further, be provided with the limit shaft 62 matched and axis hole 22 at the middle part of its contact surface, in order to better fix, the side, front and back of motor mount 2 be provided with the otic placode 21 of screw.
The present invention in use, motor mount 2 is arranged on motor 1, fixed by screw, pressing axis 5 can telescopic moving under the effect of contained spring 3, bearing pin 4 is driven to move around in pin shaft hole, when pressing axis 5 forced compression, distance between both sides bearing pin 4 narrows, the screw propeller mount pad 6 installing screw propeller 7 is contacted connection with motor mount 2, extended distance now between draw-in groove 61 is greater than the distance between bearing pin 4, the limit shaft 62 at middle part matches fixing with spacing hole 22, groove on draw-in groove 61 matches with pressing axis 5, after decontroling pressing axis 5, under the effect of spring 3, bearing pin 4 matches with the opening of the arc of draw-in groove 61 formation position limiting structure.
After installation, contact up and down between motor mount 2 with screw propeller mount pad 6 and make it horizontally rotate upper limit, bearing pin 4 match with draw-in groove 61 rotate and move up and down all spacing, formed omnibearing spacing, its material is alloy material, and intensity meets flight requirement, adopts bearing pin 4 can make spacing more firm under the influence of centrifugal force during design, rational in infrastructure, easy to use.
