The AT reverse circulation drilling rig is a new type of high-efficiency, environmentally friendly, multi-functional crawler-mounted drilling machine that uses dual-wall drill rods. After internal pipe discharge, the cuttings are collected through a cyclone collector for geological exploration sampling and analysis work. It can perform compressed air reverse circulation percussion drilling in multiple strata layers. All actions such as rig lifting, rig compensation, rod connection and disconnection, rotation and feed, leg extension, mast raising, and traveling are fully controlled by the hydraulic system, significantly reducing labor intensity while improving construction efficiency and project quality.
