Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] refer to figure 1 As shown, the novel diamond drill bit of the present invention includes a drill body 1, a fan-shaped block 2, and a nozzle 3. The fan-shaped block 2 includes several, and is arranged around the drill body 1. The nozzles 3 are arranged in two fan-shaped Between the blocks 2, a through hole 4 and a pressure head type detachable cutting tool 5 are also included. Inside (pressure head type detachable cutting tool 5 cooperates with through hole 4).

[0018] Each sector block 2 is provided with several through holes 4 , and each through hole 4 is arranged in a helical shape.

[0019] The through-holes 4 on each sector 2 are distributed symmetrically around the center of the drill body 1 (the through-holes 4 on each sector 2 are located on the same cutting line as the through-holes 4 at corresponding positions on other sector 2 ). ...

Abstract

The invention discloses a novel diamond bit which comprises a bit body, a plurality of sector blocks and water gaps. The sector blocks are arranged on the bit body in a surrounding mode, and the water gaps are formed between every two sector blocks. The novel diamond bit further comprises through holes and pressure head type detachable cutting tools, the through holes are formed in the sector blocks, and the pressure head type detachable cutting tools are detachably installed in the through holes. Each sector block is provided with the multiple through holes, and all the through holes are distributed in a spiral line shape. The through holes in the sector blocks are distributed in a central symmetrical mode around the bit body. Rock powder is accumulated in the through holes, provides abrasives for working lip faces and is beneficial to eliminating matrix polishing. The part, probably being abraded abnormally, at the hole bottom of the diamond bit can be enhanced through the through holes and the pressure head type detachable cutting tools installed in the through holes, the efficiency for smashing rock is improved, the service life of the bit is effectively prolonged, the drilling speed is effectively increased, and the novel diamond bit can be applied to drilling in hard rock or soft and hard interbedding stratums and is wider in drillable stratum range.

Description

technical field [0001] The invention belongs to the field of diamond drill drilling, and in particular relates to a novel diamond drill. Background technique [0002] When diamond bits drill into hard, dense and weakly abrasive rock formations such as hard rock and soft-hard interbedded rock, drill bit polishing and slippage often occur. It takes a lot of time and drill bits, which leads to the extension of the entire drilling construction period, low drilling speed, very low timeliness and service life of the drill bits, resulting in increased exploration costs and a significant decline in economic benefits. Solving the problem of low drilling efficiency in such rock formations is a long-standing technical problem in the drilling industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of diamond drill bit, which can prevent polishing and increase the drilling speed and drill life, and improve The ...
