Problems solved by technology

However, when the drill bit with serrated structure drill teeth is working, due to the influence of factors such as side pressure, groove depth, drill tooth lip surface structure and material, the force of each part of the drill tooth is different and the wear is not synchronized, which is easy to cause the drill bit The inner and outer drill teeth of the working part are interrupted to shorten the service life of the drill bit, which greatly increases the auxiliary drilling time such as lifting the drill bit and replacing the drill bit, resulting in a large waste of time and resources

Abstract

The invention provides a drill bit which comprises a cylindrical drill bit body and a plurality of drill teeth arrayed on the drill bit body. Each drill tooth comprises a working layer and a filling layer, the working layers are arrayed at intervals along the radial direction of the drill bit body, each filling layer is clamped between two adjacent working layers, and the hardness of the working layers is higher than that of the filling layers. The drill bit has the advantages of high drilling efficiency, difficulty in abrading and breaking the drill teeth, long service life and the like, the labor intensity of constructors is reduced, and damaged drill bit replacement time and resource waste are reduced.

Description

technical field [0001] The invention relates to the field of excavation or drilling equipment, in particular to a drill bit for excavation or drilling. Background technique [0002] In geological exploration, especially in deep hole drilling in hard rock formations, the teeth of the working part of the current drill bit are mainly planar structure teeth or serrated structure teeth. When drilling particularly hard rock formations, the drill bit with planar structure drill teeth often appears "slipping" phenomenon or slow footage due to the large contact area with the surface to be drilled. In order to solve the above problems, technicians generally use drill bits with saw-toothed drill teeth, which are usually designed with multiple rings of drill teeth arranged in sequence, thereby reducing the contact area with the surface to be drilled as a whole, and increasing the contact area between the drill teeth and the drill teeth. The contact point of the surface prevents the phe...
