Abstract
An auger drilling apparatus includes a spoil disposal box guided on the lower end of the auger leads. The auger extends vertically through the box and deposits spoil from the hole being drilled into the box. During drilling, the box rests on the ground at the top of the hole being drilled. When the box is filled, it can be raised on the leads to an elevated position and eject the spoil directly into a dump truck.
Claims12
A drilling apparatus comprising:
- an auger for drilling a hole in the ground;
- leads extending parallel to and supporting said auger and means for guiding said auger to move longitudinally of said leads during drilling;
- drive means for rotating said auger and for moving said auger longitudinally of said leads;
- and a container for receiving spoil produced by said auger during drilling, said container being guided upon a lower end of said leads, said auger extending through said container and said container being movable on said leads independently of said auger;
- means for moving said container longitudinally of said leads independently of said auger between a ground-engaging loading position, wherein the container is situated on the ground at the top of a hole being drilled by the auger to receive spoil removed from the hole by the auger, and an elevated dumping position wherein the container is raised above the ground, and means for discharging spoil from the container when the latter is in the dumping position.
