ABSTRACT OF THE DISCLOSURE The invention provides a continuous excavating apparatus principally designed for use in mining operations and includes an elongated frame having heavy upright side walls and a mobile support mechanism. At its front end the frame mounts an endless bucket line for pivotal motion about both an upright and a transverse axis, the heavy frame providing a counterbalance for the forces generated during the excavating operation. The buckets are mounted on hinge pins whose enlarged ends engage supporting sprockets in a fashion to reduce and distribute wear resultant from normal operation, and the buckets include replaceable excavating teeth enabling ready replacement when required.
