WIPO Patent Application WO/2023/240953

A1

Disclosed in the present invention are an anti-freezing mechanism for an excavator crowding air bag and an anti-freezing system using same. The anti-freezing mechanism comprises an air conveying part, an air guide part, an anti-freezing part and a rotation stopping part, wherein the air conveying part comprises a protective shell, an air conveying pipe inside the protective shell, a first magnetic block fixed to one side of the protective shell, and insertion connection pipes arranged in an extending manner at two ends of the air conveying pipe; and the air guide part comprises air guide pipes matched with the insertion connection pipes. In the anti-freezing mechanism for an excavator crowding air bag and the anti-freezing system using same, the air conveying part can be rotated by means of pressing the rotation stopping part, so that the anti-freezing part can be located above or below same, and, by using different manners such as alcohol volatilization or intermittent dripping of alcohol to make same mixed with air, the mixed gas can be conveyed into an air bag, thus effectively preventing the mixed gas from freezing due to low temperature and effectively protecting the air bag.
