Description
Technical field
The utility model relates to engineering technical field of mechanical equipment, particularly a kind of major diameter staged scraper composite sheet reaming bit.
Background technology
In the large diameter borehole construction of present domestic solid mineral exploration, according to technology needs, need to carry out major diameter and creep into.Hard and when using general reaming bit to creep into sub-surface in various, efficiency is low, and engineering progress is slow, and has considerable restraint for the degree of depth of boring, and cannot reach boring arbitrarily can the effect of reaming; Prior art can reach the reaming bit of any degree of depth, has and cannot carry out reaming by the hard and following bottom of centering, be only applicable to loose bottom.If China Patent No. is the utility model patent of CN201020137790.5, publication date is on November 3rd, 2010, disclose the reaming bit for scall large diameter borehole, the technical scheme adopted is: comprise a body, body upper end is processed with the screw thread connected with drilling tool, lower end is connected with starter, body is welded with wedge shape wing body, and the face soldering of wedge shape wing body sword has antifriction alloy; Every three of wedge shape wing body is one group, and each group is evenly distributed on around body.In such scheme, shaft design wedge shape wing body, can rapidly and efficiently creep into, but reaming bit is only applicable to scall, cannot carries out reaming to the boring of medium ground.
Utility model content
In view of this, the purpose of this utility model is for prior art Problems existing, proposes a kind of major diameter staged scraper composite sheet reaming bit, can be used for the reaming of medium ground boring.
The utility model discloses a kind of major diameter staged scraper composite sheet reaming bit, comprise drill bit body and the starter being arranged at described drill bit body lower end, described drill bit body is provided with multiple wing body, and described wing body is ladder-type structure.
The beneficial effects of the utility model show:
A kind of major diameter staged scraper composite sheet reaming bit is provided, directly can creeps into boring, solve general drill bit and easily break tooth, inefficient problem; Staged wing body is provided with sword face, and be applicable to medium ground large diameter borehole construction, can rapidly and efficiently creep into, efficiency is more than 2 times, general drill bit; For probing industry provides new drill at medium ground construction large diameter borehole, be applicable to any deep drilling, widely applicable, and manufacturing process is simple, and its structure is simple.
