Abstract
The utility model provides an inwards concave drilling bit of a super-strong diamond composite sheet, belonging to a rock breaking tool. The inwards concave drilling bit is mainly used for gas drainage boreholes of coal mines, water detecting holes, grouting holes and geological prospecting boreholes. The inwards concave drilling bit comprises a drilling rod and a drilling bit, wherein the drilling bit is connected with the drilling rod by threads. The inwards concave drilling bit is characterized in that the drilling bit comprises a diamond composite sheet, a rock breaking post, a water hole and a diameter-keeping strip; and the drilling bit is embedded with the rock breaking post and soldered with the diamond composite sheet and the diameter-keeping strip. The inwards drilling bit can be drilled in hard rock layers, has good wearability, strong anti-twisting performance, quick rock-breaking speed, good chip cooling characteristic, unobvious diameter shrinkage phenomenon and high construction efficiency.
Description
Technical field
The utility model belongs to rock crushing tool, is mainly used in the gas discharge in mine hole, visits water hole, injected hole and geological prospecting borehole, is specifically related to a kind of ultrastrong diamond compact indent drill bit.
Background technology
Existing drill bit abrasion resistance is lower, in actual applications, the easy avalanche of diamond compact, the undergauge phenomenon is more obvious in boring procedure, thereby influences single the bit bore degree of depth.
Summary of the invention
The utility model aims to provide the ultrastrong diamond compact indent drill bit that a kind of abrasion resistance is better, toughness is higher, the undergauge phenomenon is not obvious, application life is long.
The realization the technical solution of the utility model is: comprise drilling rod, drill bit, drill bit and drilling rod are by being threaded, it is characterized in that drill bit comprises diamond compact, broken rock pillar, water hole, guarantor footpath bar, being inlaid with brokenly rock pillar and soldering on the drill bit has diamond compact and protects the footpath bar.
The utility model can pierce the medium ground, and abrasion resistance is good, resistance to torsion is strong, and broken rock speed is very fast, and the cooling chip removal is good, and the undergauge phenomenon is not obvious, the efficiency of construction height.
