Abstract
A bullet-carried rust removal mechanism and a rust removal device are provided. The bullet-carried rust removal mechanism includes bullets, the bullets can reciprocate linearly under the driving of an external driving mechanism to thereby repeatedly knock a surface to be derusted, and an end of each of the bullets away from the driving mechanism is a knocking portion for derusting conveniently. The bullet-carried rust removal mechanism has a relatively small volume and a position to be derusted can be accurately positioned during derusting.
Claims18
A bullet-carried rust removal mechanism comprising:
- bullets and a driving mechanism, wherein the bullets are configured for reciprocating linearly under the driving of the driving mechanism to thereby repeatedly knock a surface to be derusted;
- and an end of each of the bullets away from the driving mechanism is a knocking portion for derusting;
- wherein the bullet-carried rust removal mechanism further comprises bullet-carried rust removal mechanism bases;
- wherein each of the bullet-carried rust removal mechanism bases is provided with a gas receiving cavity, and the driving mechanism is communicated with the gas receiving cavity;
- and
- wherein the driving mechanism is provided with a gas distribution mechanism, each of the bullets is movably embedded in the gas receiving cavity, a side wall of each of the bullets abuts against an inner wall of the gas receiving cavity to isolate gas pressure in the gas receiving cavity from atmosphere, the gas distribution mechanism is configured to introduce a gas into the gas receiving cavity to thereby drive each of the bullets to knock the surface to be derusted, and each of the bullets returned back after knocking the surface to be derusted.
