Method and Means for Drilling an Earthen Hole

Abstract

An earthen hole drilling device having an elongated tube with first and second ends where a source of vacuum pressure is connected to the first end and shroud is connected to the second end. A waterline is connected to a source of pressurized water at one end and extends into an interior of the shroud through an opening where the line is connected to a nozzle that is angled at 45°. The shroud additionally has at least one opening that allows air induction/conduction through the shroud in order to dislodge material that accumulates within the shroud.

1 . An earthen hole drilling device comprising:
 an elongated tube having first and second ends;   a source of vacuum pressure connected to the first end of the tube;   a shroud connected to the second end of the tube;   a water line connected to a source of pressurized water at one end and extends into an interior of the shroud through an opening where the line is connected to a nozzle; and   the shroud has at least one opening.   
     
     
         2 . The device of  claim 1  wherein the nozzle is disposed within the interior of the shroud. 
     
     
         3 . The device of  claim 1  wherein the line is bent such that the nozzle is set to spray at approximately a 45° angle in relation to a central axis of the tube. 
     
     
         4 . The device of  claim 1  wherein air flows through the at least one opening to create air induction that assists in dislodging material that accumulates on the shroud.
