the utility model provides a quick-connection type spiral drill rod for pressure relief, which comprises a drill rod body, wherein one end of the drill rod body is provided with a quick-insertion type male connector, the other end of the drill rod body is provided with a quick-insertion type female connector, and a steel belt is spirally arranged on the drill rod body.
Further, the male joint comprises an outer hexagonal joint and a bolt, the outer hexagonal joint is hollow, one end of the outer hexagonal joint is connected with the drill rod body, a groove is formed in the other end of the outer hexagonal joint, a first radial through hole is formed in the outer hexagonal joint and communicated with the groove, and the bolt is embedded into the first through hole.
Further, the inside spring that is equipped with of recess, spring one end is equipped with the screw, and the other end is equipped with the inner pin, one side that the recess is close to the body of drilling rod is equipped with the stopper, the inner pin embedding is in the stopper, screw threaded connection is in the one side of keeping away from the body of drilling rod.
Further, the bolt is fixed in the first through hole through the inner pin.
Further, the female joint comprises an inner hexagonal joint, and a second through hole corresponding to the first through hole is formed in the inner hexagonal joint.
Further, the body of the drilling rod is a hexagonal hollow rod.
The utility model has the technical effects that:
compared with the prior art, the quick-connection type spiral drill rod for pressure relief, which is disclosed by the utility model, has the advantages that the traditional threaded drill rod is changed into a quick-insertion type drill rod, so that the changing efficiency of a drill bit is greatly improved; the multiple drill rods are combined for use, so that a flow guide channel of the steel belt for the crushed slag scraps is prolonged, and the problem of accumulation of the crushed slag scraps in the drilled hole is solved; through setting up interior hexagonal joint and outer hexagonal joint, reduced the loss of drilling rod body torsion greatly.
