Abstract
The invention relates to a tooth-shaped drill bit for exploratory drilling. The tooth-shaped drill bit comprises a hollow cylindrical steel body. Multiple drill bit green bodies are evenly arranged at the bottom of the cylindrical steel body at intervals and are drill bit bodies of tooth-shaped structures. The tooth-shaped drill bit for exploratory drilling is compact and reasonable in structure, convenient to manufacture, capable of effectively preventing the drill bit bodies from cracking in drilling as the drill bit green bodies of the tooth-shaped structures are evenly arranged at intervals. The service life of the drill bit bodies is prolonged and the working efficiency is improved.
Description
Technical field
The present invention relates to geological prospecting equipment technical field, especially a kind of probing jagged bit.
Background technology
Probing is an important technical in geological prospecting work.With rig, from earth's surface, creep into downwards ， stratum and form cylindrical bore, to differentiate and to divide stratum.Can be from boring different depth obtain rock core, sample ore, soil sample and analyze and research, in order to measure physics, mechanical property and the index of rock and soil layer, provide design needs.Rig used is mainly divided into two kinds of swinging and impact types.
In prior art, probing adopts the structure at the bottom of goose soft rock with the head of drill bit, drill bit in drilling process, when running into hard bottom, the phenomenon of easily breaking, drilling life of bit is low, to boring work, has brought inconvenience, affects probing work.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of probing jagged bit rational in infrastructure, thereby effectively prevents the phenomenon that drill bit breaks in boring procedure, extends the application life of drill bit.
The technical solution adopted in the present invention is as follows:
A jagged bit, comprises into hollow cylindrical steel body, and described cylindrical steel body bottom even is arranged at intervals with a plurality of bit matrixes, and described bit matrix is tooth-shape structure drill bit.
Further improvement as technique scheme:
Described bit matrix is welded in the bottom of cylindrical steel body;
Described cylindrical steel body bottom even is arranged at intervals with six bit matrixes.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, rationally, easy to make, by the bit matrix of even spaced tooth-shape structure, effectively prevent the phenomenon of breaking in drill bit drilling process, prolongation drilling life of bit, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, cylindrical steel body; 2, bit matrix.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the probing jagged bit of the present embodiment, comprises into hollow cylindrical steel body 1, and cylindrical steel body 1 bottom even is arranged at intervals with a plurality of bit matrixes 2, and bit matrix 2 is tooth-shape structure drill bit.
Bit matrix 2 is welded in the bottom of cylindrical steel body 1.
Cylindrical steel body 1 bottom even is arranged at intervals with six bit matrixes 2.
In actual use procedure, by being evenly arranged at intervals with bit matrix 2, drill bit creeps into the phenomenon that Shi Buhui breaks, and drilling life of bit is long, and drilling quality is excellent, is conducive to differentiate and divide the work on stratum.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
Claims (3)
1. a probing jagged bit, is characterized in that: comprise into hollow cylindrical steel body (1), described cylindrical steel body (1) bottom even is arranged at intervals with a plurality of bit matrixes (2), and described bit matrix (2) is tooth-shape structure drill bit.
2. probing jagged bit as claimed in claim 1, is characterized in that: described bit matrix (2) is welded in the bottom of cylindrical steel body (1).
