Abstract (en)
[origin: EP0919669A2] The drilling bucket comprises a housing (22) with a frame (24), suspended from its upper end, and two scoops (28, 30) pivoting about parallel axes. It incorporates a system for correcting the inclination of the bucket, consisting of two shoes (32, 34), each having side panels perpendicular to the axes of the pivots and parallel to the vertical axis, connected to a central member located opposite the sides of the frame. Each shoe is equipped with separate mechanisms for adjusting its upper and lower ends.
