Abstract:
1. A soil drill rod extractor for insertion and removal of a soil drill rod from the ground, comprising: (a) said drill rod having a plurality of alternating rod threads, (b) an extraction collar surrounding said drill rod having a smooth and un-threaded exterior surface and internal threads rotatably engaging said rod threads, (c) a guide sleeve perpendicularly connected to a flat ground plate for stabilization with the ground surface and a sleeve opening through which said drill rod travels down into the ground precisely perpendicular to the ground surface, whereby impact of said drill rod forces said drill rod into the ground perpendicular to the ground surface, whereby rotation of said extraction collar causes travel of said extraction collar down the said drill rod into contact with said guide sleeve, whereby further rotation of said extraction collar results in upward force upon said drill rod, whereby said drill rod travels up out of the ground.
