AI Technical Summary
Existing drilling equipment for highway construction is not convenient for adjusting the drilling direction according to construction needs, which makes it inconvenient to use. In addition, the dust generated during drilling affects visibility and health and safety.
The base plate features a swivel caster for easy movement, combined with angle and height adjustment mechanisms. The worm gear driven by the motor meshes with the worm wheel to achieve flexible adjustment of the drill bit's direction and height. It is also equipped with a dust removal mechanism that uses a water pump and atomizing nozzles to clean up dust during drilling.
It enables flexible adjustment of the drill bit direction and height, improves the practicality of the device, reduces dust during drilling, and protects the health and safety of users.
