Abstract

The utility model provides a geological drill bit with a super-high matrix and water, which comprises a drill bit mounting seat and a drill bit arranged above the drill bit mounting seat; the drill bit top is equipped with first round hole, and the drill bit top is equipped with the recess, and the recess is equipped with threely and around drill bit axle center evenly distributed, and the drill bit lateral wall is equipped with the water hole, and the equidistance is equipped with two water holes between two recesses. The utility model discloses when the drill bit operation, through water hole water injection cooling, avoid high temperature to cause the rising of drill bit wearing and tearing, the difficult fracture of matrix layer simultaneously.

Description

Geological drill bit with ultrahigh matrix and water-permeable function

Technical Field

The utility model mainly relates to a geological exploration technical field especially relates to a geological drill bit that superelevation matrix can lead to water.

Background

The drill bit is installed at the front end of a drilling tool used for geological drilling, the matrix of the drill bit in the current market is low, meanwhile, due to the fact that the temperature of the drill bit is increased when the drill bit works, the abrasion speed of the drill bit is increased, the matrix is easy to break, and the working cost and the working progress of geological exploration are increased to a certain extent when the drill bit is replaced.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a geological drill bit with a super-high matrix and water, which comprises a drill bit mounting seat 1 and a drill bit 2 arranged above the drill bit mounting seat 1; 2 tops of drill bit are equipped with first round hole 3, and 2 tops of drill bit are equipped with recess 4, recess 4 is equipped with threely and around 2 axle center evenly distributed of drill bit, and 2 lateral walls of drill bit are equipped with water hole 5, two the equidistance is equipped with two water holes 5 between the recess 4.

Preferably, the depth of the groove 4 is 3mm to 4 mm.

Preferably, the water hole 5 extends through the drill 2 to the first circular hole 3.

Preferably, a second round hole 6 is arranged in the drill mounting seat 1.

Preferably, the second circular hole 6 is internally threaded.

Preferably, the drill bit 2 is fixedly welded to the drill bit mounting seat 1.

Preferably, the top surface of the drill bit 2 is provided with a groove surface structure.

The utility model has the advantages that:

1. when the drill bit runs, water is injected through the water holes to reduce the temperature, so that the increase of the abrasion degree of the drill bit caused by high temperature is avoided; and the carcass layer is not easy to break.
