Abstract

The invention relates to the field of engineering drilling and coal seam prospecting drilling tools, and specifically discloses a diamond coated drill bit, which comprises a crushing head, a first connecting end, a second connecting end, a reinforcing mechanism, wherein the first connecting end is integrally formed with the crushing head and located at the lower end of the crushing head, the second connecting end is arranged at the lower end of the first connecting end, and the reinforcing mechanism is arranged at the lower portion of the side face of the second connecting end; a drill pipe connection end, a first abrasive water jet channel, a second abrasive water jet channel, a third abrasive water jet channel, and an abrasive water jet port communicate with each other; and the crushinghead, the first connecting end, the second connecting end, a protective sleeve, and the outer wall of a curved plate are all provided with a nano diamond coating layer. The diamond coated drill bit can fix a hole wall while drilling a hole during ring drilling under sedimentary rock, the phenomenon of drill falling caused by the collapse during the drill retracting process is greatly reduced; thedrill bit ensures the overall stability of the drill bit while adopting split design, the drill bit is split after the drilling is completed, the internal abrasive channel of the drill bit is cleaned,and the occurrence of blockage is effectively prevented.

Description

technical field [0001] The invention relates to the field of drilling tool accessories for engineering drilling and coal seam prospecting, in particular to a diamond-coated drill bit. Background technique [0002] In the coal mine drilling process, the drill bit is the main tool for breaking rock, and the borehole is formed by breaking the rock with the drill bit. Whether a wellbore is formed well or not, the length of time it takes is not only related to the characteristics of the drilled formation rock and the performance of the drill bit itself, but also to the degree of matching between the drill bit and the formation. The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the overall cost of drilling. The roadway surrounding rock in coal mines is mainly sedimentary rock, and the strength of sedimentary rock is low. Conventional drill bits are used for drilling, especially when drilling deep holes. Due to the deve...
