Q1: What is a hand-crank wheel drilling machine? What scenarios is it mainly used for?
A: A hand-crank wheel drilling machine refers to equipment that controls the lifting and downward pressure of the drill bit by manually turning a handwheel (combined with a gear rack or chain reduction mechanism). It is widely used for geological exploration sampling, agricultural soil surveys, and orchard fertilization.
Q2: How deep and how wide can a hand-crank wheel drilling machine drill?
A: In standard configuration, The maximum drilling depth is 70 centimeters and the maximum drilling diameter is 60 centimeters.
Q3: If jamming occurs during drilling, can the handwheel reverse to back out the drill?
A: Absolutely. The handwheel mechanism supports both clockwise and counterclockwise operation, and the power head supports reverse rotation. Once hitting an underground obstacle and jamming, simply turn the handwheel in reverse and reverse the power head to easily back the drill out of the hole. Clear the obstacle and continue working.
