Abstract
The utility model relates to a stepped drill bit for drilling, which comprises a hollow cylindrical steel body, wherein drill bit matrixes are uniformly arranged at the bottom of the cylindrical steel body at intervals; a step is arranged at the bottom of each drill bit matrix; a plurality of alloy blocks are mounted on the inner side and the outer side of each drill bit matrix. The stepped drill bit is compact and reasonable in structure, and convenient to manufacture; the stepped drill bit matrixes are uniformly arranged at intervals, so that the drilling speed of the drill bit is increased, vibration is alleviated, the quality of a drill hole is improved, and the working efficiency is improved.
Description
Technical field
The utility model relates to geological prospecting equipment technical field, especially a kind of step probing drill bit.
Background technology
Probing is an important technical in geological prospecting work.From earth's surface, creep into downwards with rig, in stratum, 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 is in drilling process, and its rate of penetration is slow, and vibrations are large, has brought inconvenience to boring work, affects probing work.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of step probing drill bit rational in infrastructure, thereby improves rate of penetration, reduces vibrations, increases work efficiency.
The technical scheme that the utility model adopts is as follows:
A kind of step probing drill bit, comprise into hollow cylindrical steel body, described cylindrical steel body bottom even is arranged at intervals with bit matrix, and the bottom of described bit matrix is provided with step, and the inner side and the outside that are positioned at each bit matrix are all provided with multiple alloy blocks.
As the further improvement of technique scheme:
Described bit matrix is welded in the bottom of cylindrical steel body;
Described cylindrical steel body bottom is provided with eight bit matrixes.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to make, by the bit matrix of even spaced step, has improved the speed that drill bit creeps into, and has reduced vibrations, improves drilling quality, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, cylindrical steel body; 2, alloy block; 3, bit matrix; 4, step.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the step probing drill bit of the present embodiment, comprises into hollow cylindrical steel body 1, and cylindrical steel body 1 bottom even is arranged at intervals with bit matrix 3, the bottom of bit matrix 3 is provided with step 4, and the inner side and the outside that are positioned at each bit matrix 3 are all provided with multiple 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 3, it is fast that drill bit creeps into speed per hour degree, reduces vibrations, and operating efficiency is high, and drilling quality is excellent, is conducive to differentiate and divide the work on stratum.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
