Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention will be further described,

[0014] Such as Figure 1 to Figure 4 As shown, the present invention provides a quick-release mechanism for a propeller, which includes a motor 1 and a propeller 7 installed at the end of the aircraft wing, the propeller mount 6 is movably connected to the bottom of the propeller 7, and the propeller mount 6 is provided with an opening relative to the bottom of the propeller mount 6. Arc-shaped slot 61. And the utilization screw of motor 1 is fixed with cuboid motor mount 2, is provided with the pressing shaft 5 of telescopic connection along the both sides of length direction, is respectively provided with bearing pin 4 on the horizontal direction perpendicular to pressing shaft 5, bearing pin 4 The inner spring 3 moves with the expansion and contraction of the pressing shaft 5. The groove 61 of the propeller mounting base 6 is provided with a groove suitable for the pr...

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 [0001] The invention relates to a propeller mechanism of a plant protection unmanned aerial vehicle, in particular to a quick-release mechanism of a propeller. Background technique [0002] At present, domestic plant protection UAV technology is developing rapidly. Relying on its advantages of high efficiency, flexible operation and strong adaptability, it has begun to gradually replace the method of manual spraying. The multi-rotor plant protection drone is the most numerous among the many plant protection drones. It relies on the lift of the rotor to drive the spraying of the medicine box. It has a large load capacity, is easy to control, and is widely used. However, as a multi-rotor structure, the terrain in the plant protection process is complex, and the rotor itself is fragile, and it is easy to appear under the action of external force. In actual use, it is inevitable that the rotor will be damaged. When the rotor is damaged or repaired and replaced, ...
