Abstract

The invention provides a diamond drill bit which is easy to install and use and an installation method thereof, comprising a drill barrel, a cooling hole, a connecting barrel structure, a drill gear structure, a connecting rod, a hex head bolt and a discharge hole, and the drill bit barrel is welded on the upper end of the connecting barrel structure The cooling holes are set longitudinally on the left and right sides of the front surface of the drill barrel; the drill gear structure bolts are connected to the upper end of the drill bit barrel; the connecting rod is inserted into the lower end of the connecting barrel structure; side middle position. The outer surface of the drill bit barrel of the present invention is provided with the setting of the scale line, which is convenient to check the drilling depth of the drill bit and ensures the smooth progress of the drilling work; the setting of the connecting barrel can quickly install the drill bit, and the setting of the safety ring can The drill bit and the drilling machine are connected with a safety rope to ensure safety during the drilling operation.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a diamond drill bit which is easy to install and use and an installation method thereof. Background technique [0002] The drill that makes the cutting edge is called a diamond drill. One-piece drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new technologies of drilling in the world in the 1980s. Field use proves that when drilling in soft-medium hard formations, diamond bits have the advantages of fast speed, more footage, long life, stable work, fewer downhole accidents, and good wellbore quality. The diamond drill bit not only has a long service life, but also can be reused. The diamond drill bit returned to the factory for repair has the same effect as the factory diamond drill bit, which can save a lot of drilling costs....
