Shaft drilling machine










Image Number 3 for United States Patent #4483403.

A shaft drilling machine has a circularly moving drilling head. The drilling head is angularly oriented with respect to the longitudinal axis of the shaft sought to be drilled. Loosened material is transported from the lower portion of the shaft by pickup means, moving with the drilling head, and taken to the upper portion of the angularly oriented bottom of the shaft, whereupon the loosened material or borings slide, by gravity, to a centrally located vertical conveyor mechanism for final removal of the material or borings from the shaft.
