Abstract
The utility model provides a double-water hole diamond compact anchor rod bit, and belongs to rock breaking tools. A connection bridge is arranged between two knife wings of the bit, and the lower portion of each diamond compact is provided with a water outlet hole. Scouring capacity of the diamond compact bit on waste slag in the drilling process is improved, a drill body generates heat by friction in a working condition, the temperature can be timely reduced through the two water holes even when sparks are generated, the temperature of the surface of the drill body in use is effectively reduced, and accordingly drilling stress of the diamond compact is reduced. The problems that according to a common diamond compact anchor rod bit, due to the overhigh temperature, pieces are too early to fall and debris fails are well solved, abrasion of the drill body is slowed accordingly through water flushing and temperature reducing, drilling efficiency of the bit is greatly improved, and the servile life of the bit is greatly prolonged.
Description
Technical field
The utility model belongs to rock crushing tool, is mainly used in being applicable to creeping into of department's bolting with wire mesh rock pores such as mine, traffic, water power, is specifically related to a kind of oval external diameter anchor rod drill bit of diamond compact.
Background technology
China Patent No. is in 201120287795.0, to disclose a kind of " anchor rod drill bit of diamond compact ", it comprises drill bit, drilling rod, drill bit and drilling rod are threaded connection, it is characterized in that drill bit comprises diamond compact, the water hole of spheric, on drill bit, be arranged with two wings, equal soldering spheric diamond compact on each wing, water hole is longitudinally through drill bit, drilling rod.It is in actual use, and it is too fast that drill body heats up, and causes diamond compact premature failure, drill body serious wear, and wherein too small the or water outlet of weep hole is inhomogeneous is the one of the main reasons that causes temperature of diamond bit too high.
Background technology
The utility model aims to provide that a kind of water yield is large, and water outlet is even, and water spraying direction is accurate, the anchor rod drill bit of diamond compact that application life is longer.
Realizing this practical novel technical scheme is: between two wings of drill bit, be provided with connecting bridge, the fluctuation of drill body both wings is reduced; Below each diamond compact, all set out water hole.
The utility model has two weep holes, to diamond compact difference while spray cooling.
The utility model improved diamond compact bit at drilling process the scouring capability to waste residue, drill body and operating mode frictional heat, while even producing spark, can lower the temperature in time by two water holes, thereby effectively lowered the temperature on surface during drill body is used, thereby lowered the stress that creeps into of diamond compact.Preferably resolve common anchor rod drill bit of diamond compact, due to excess Temperature, cause falling too early the Problem of Failure such as sheet, fragment, by bath, lower the temperature, the wearing and tearing of drill body are also slowed down thereupon, thereby have greatly improved drilling efficiency and the bit life of drill bit.
