Abstract
The invention relates to a high-strength drill bit for exploratory drilling. The high-strength drill bit for exploratory drilling comprises a hollow cylindrical steel body. Drill bit green bodies are evenly arranged at the bottom of the cylindrical steel body at intervals. A step is arranged at the bottom of each drill bit green body. A through hole is formed in the lower portion of each drill bit green body. The high-strength drill bit further comprises reinforced ribs which penetrate through the through holes formed in the lower portions of the drill bit green bodies respectively. Multiple alloy blocks are installed on inner sides and outer sides of the drill bit green bodies. The high-strength drill bit for exploratory drilling is compact and reasonable in structure and convenient to manufacture. The drill bit green bodies are evenly arranged at intervals and the reinforced ribs are installed among the drill bit green bodies, so that the strength of the drill bit is effectively improved, the service life of the drill bit 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 high strength drill 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 flat-bottom structure with drill bit, and drill bit, in drilling process, when running into hard bottom, easily damages, and its intensity is low, has brought inconvenience to boring work, and application life is short, affects probing work.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of probing rational in infrastructure high strength drill bit, thereby has improved the intensity of drill bit, extends the application life of drill bit.
The technical solution adopted in the present invention is as follows:
A kind of probing high strength drill bit, comprise into hollow cylindrical steel body, described cylindrical steel body bottom even is arranged at intervals with bit matrix, the bottom of single bit matrix is provided with step, the bottom of single bit matrix has through hole, also comprise reinforcing rib, described reinforcing rib is through the through hole of each bit matrix bottom; The inner side and the outside that are positioned at each bit matrix are all provided with a plurality of alloy blocks.
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 12 bit matrixes.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy to make by even spaced bit matrix, and is provided with reinforcing rib between each bit matrix, effectively raises the intensity of drill bit, extends 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, alloy block; 3, reinforcing rib; 4, bit matrix; 5, step.
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 of the present embodiment high strength drill bit, comprise into hollow cylindrical steel body 1, cylindrical steel body 1 bottom even is arranged at intervals with bit matrix 4, the bottom of single bit matrix 4 is provided with step 5, the bottom of single bit matrix 4 has through hole, also comprises reinforcing rib 3, and reinforcing rib 3 is through the through hole of each bit matrix 4 bottom; The inner side and the outside that are positioned at each bit matrix 4 are all provided with a plurality of alloy blocks 2.The design of alloy block 2 has improved the intensity of drill bit.
In actual use procedure, by being evenly arranged at intervals with bit matrix 4, not fragile when drill bit creeps into, formidable opponent is high, long service life, 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.
