Problems solved by technology
[0002] Shock-resistant parts need to be installed on the propeller so that the leading edge of the propeller has better shock resistance; at present, the existing propellers have poor shock resistance, and the processing of the shock-resistant parts is difficult, the process is complicated, and the cost is high, which cannot meet the needs of the market
[0003] For example, on agricultural plant protection drones, it is difficult to manufacture impact-resistant components, and the impact-resistant components cannot be installed on the leading edge of the propeller, which makes the impact resistance of the drone poor.

Embodiment Construction
[0012] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a shock-resistant propeller blade proposed by the present invention.
[0013] refer to figure 1 , an impact-resistant propeller blade proposed by the present invention, the leading edge 3 of the blade 1 is bonded with 3M adhesive tape 2 .
[0014] In the working process of this embodiment, the blade 1 is subjected to a large air resistance when rotating, and the air resistance causes great wear and tear on the blade 1, wherein the leading edge 3 of the blade 1 receives the largest air resistance; the 3M adhesive tape 2 is bonded On the leading edge 3 of the blade 1, the 3M tape 2 effectively protects the leading edge 3 of the blade 1 and prevents the wear of the blade 1; the 3M tape 2 is easy to replace, easy to produce, stable in bonding, and good in use.
[0015] In a specific embodiment, the surface of the 3M adhesive tape 2 is smooth and wrinkle-free, which reduces the frictional resistan...

The invention discloses an impact resistance propeller blade. A 3M adhesive tape is adhered to the front edge of the blade, and the surface of the 3M adhesive tape is smooth and free from folds; the thickness of the 3M adhesive tape is gradually increased in the direction from blade handle of the blade to blade tip of the blade; and the width of the 3M adhesive tape is 30%-40% that of the blade. According to the impact resistance propeller blade disclosed by the invention, in the working process, during rotation, great air resistance is pressed onto the blade; large abrasion is generated on the blade by the air resistance, and the air resistance pressed onto the front edge of the blade is the largest; the 3M adhesive tape is adhered to the front edge of the blade, and is used for effectively protecting the front edge of the blade, so that the abrasion of the blade is avoided; and the 3M adhesive tape is easy to exchange, easy to produce, stable in adhesion and good in using effect.
Description
technical field [0001] The invention relates to the field of aviation equipment, in particular to an impact-resistant propeller blade. Background technique [0002] Shock-resistant parts need to be installed on the propeller so that the leading edge of the propeller has better shock resistance; at present, the existing propellers have poor shock resistance, and the processing of the shock-resistant parts is difficult, the process is complicated, and the cost is high, which cannot meet the needs of the market . [0003] For example, on agricultural plant protection drones, it is difficult to manufacture impact-resistant components, and the impact-resistant components cannot be installed on the leading edge of the propeller, which makes the impact resistance of the drone poor. Contents of the invention [0004] In order to solve the technical problems existing in the background technology, the present invention proposes an impact-resistant propeller blade, which has simple ...
