  • Automated core drilling device capable of mating with a center-mounted core-catching device
    Patent number: 9186730
    Abstract: An automated core drilling device comprising a rigid drilling tower, a floating chuck assembly, and a drill bit. Rigid drilling tower comprising at least three vertical column members, a lower perimeter frame, and an upper perimeter frame. Floating chuck assembly comprising a drill bit axis-of-rotation vertical clearance channel, at least three horizontal support arms, at least three feed motor platforms, at least three feed motors, a hub casing, a hollow-centered bit driveshaft, a bit driveshaft sprocket, an offset spindle driveshaft sprocket, an offset spindle driveshaft, and an offset spindle motor. An automated core drilling device further comprising a computer with custom software, a monitor point for the electric current draw of said offset spindle motor or a monitor point for the revolution rate of said offset spindle driveshaft, and a control point for the electric current draw of each of said at least three feed motors.
