Abstract

The invention provides a shaft sealing washer, a spraying device and an unmanned aerial vehicle. The shaft sealing washer is used for mounting a drive shaft and comprises a sealing washer body; the sealing washer body is provided with a first end and a second end opposite to the first end; the sealing washer body is provided with an assembly through hole penetrating through the first end and the second end of the sealing washer body; the first end of the sealing washer body is provided with a contracting groove close to the assembly through hole; a contact portion, between the assembly through hole and the contracting groove, of the sealing washer body is elastic; and when the drive shaft penetrates through the assembly through hole, the contact portion of the sealing washer body moves towards the contracting groove under abutting-pressing of the drive shaft to generate elastic deformation. By the adoption of the technical scheme, the technical problem that sealing performance between a drive shaft and a mounting shell is poor due to poor elastic deformation performance of a sealing washer in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle equipment, and more specifically relates to a shaft sealing gasket, a spraying device and an unmanned aerial vehicle. Background technique [0002] In recent years, with the rapid development of multi-rotor aircraft technology (that is, UAV technology), UAV has the advantages of flexible maneuverability, fast response, unmanned flight, and low operation requirements, which has caused the development of UAV in many fields. Application, especially in the field of agricultural plant protection, the application of plant protection drones to spray crops not only improves the efficiency of spraying work, but also effectively protects farmers from spraying liquid damage and protects the health of farmers. [0003] In the prior art quality assurance UAV, the spraying device on the plant protection UAV is one of the important components of the spraying work during the application of the pla...
