Abstract

1437420 Boring earth TIGRE TIERRA INC 22 Aug 1973 [23 Aug 1972] 39748/73 Heading E1F Apparatus for drilling in an earth formation comprises a rotary drill rod 2 having a percussive bit 7 at one end, drive means 5 retractably inserted in an axial bore in the rod and comprising a piston-like member 88, in sliding engagement with the wails of the bore, and a fluid operated hammer 80 reciprocating between the member 88 and an abutment 3 operatively connected with the bit, and passages for supplying fluid to the hammer and for exhausting fluid therefrom to discharge adjacent the bit The drive means includes an anvil 38 which is connected by dowel 76 to a swivel pin 48 on which is keyed for axial sliding a swivel head 44 which rotalably supports a core-barrelling tube 40 which is biased away from the anvil by spring 52. Thus the core-travelling tube 40 can be drawn up the rod 2 by means engaging spearhead 94. Hammer-operating fluid is exhausted through ports 104 in the anvil and passes down flutes 108 in the wail of drill rod section 2' to ports 32 in the working face 12 of the bit 7. The fluid also serves to flush out material from around the tube 40 as it is being lowered into place. The tube is hammered down by the action of the anvil 38 on the swivel head 44 until the mechanism reaches the level at which the piston engages the shoulder 3. The core-barrelling tube may be temporarily replaced by a plug when it is desired to drill without coring.
