AI Technical Summary
Existing open-air blasting hole cleaning devices are difficult to effectively clean debris on the inner surface of the blasting hole, and it is impossible to completely clean the debris in the hole by only sucking dust through negative pressure.
A powerful fan-driven vacuum tube is combined with an auger blade. The vacuum tube rotates at the bottom of the fixed plate and drives the auger blade to scrape away debris. At the same time, the vacuum tube is used to extract dust in the hole to scrape and clean debris on the surface of the blasting hole.
It achieves efficient scraping of debris and cleaning of dust on the inner surface of open-pit blasting holes, reduces construction difficulty, and provides convenience for subsequent blasting operations.
