Abstract
The utility model relates to an anti-deviating drill bit for exploration drilling. The anti-deviating drill bit comprises a hollow cylindrical steel body, wherein drilling bit matrixes are arranged at the bottom of the cylindrical steel body at equal intervals, each drilling bit matrix adopts a turbination structure, steps are arranged at the outer part of each drilling bit matrix, and a plurality of alloy blocks are arranged on the inner side and the outer side of each drilling bit matrix. The anti-deviating drill bit provided by the utility model is compact and reasonable in structure, and convenient to manufacture, and as the drilling bit matrixes are arranged at equal intervals, deviation of the drilling bit during drilling is effectively avoided, and the quality of drilling and working efficiency are improved.
Description
Technical field
The utility model relates to geological prospecting equipment technical field, especially a kind of anti-deviation probing drill bit.
Background technology
Probing is an important technical in geological prospecting work.With rig, from earth's surface, creep into downwards, 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, in drilling process, when running into hard bottom, the phenomenon of sideslip easily occurs, and cannot feel relieved, and 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 anti-deviation probing drill bit rational in infrastructure, thereby effectively prevents that drill bit from the phenomenon of sideslip occurring in boring procedure, feels relieved effective, and drilling quality is excellent.
The technical scheme that the utility model adopts is as follows:
A kind of anti-deviation probing drill bit, comprise into hollow cylindrical steel body, described cylindrical steel body bottom even is arranged at intervals with bit matrix, single bit matrix becomes turbination structure, the outer setting of single bit matrix has step, and 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 ten bit matrixes.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to make, by even spaced bit matrix, effectively prevents from occurring in drill bit drilling process the phenomenon of sideslip, 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 anti-deviation probing drill bit of the present embodiment, comprise into hollow cylindrical steel body 1, cylindrical steel body 1 bottom even is arranged at intervals with bit matrix 3,3 one-tenth turbination structures of single bit matrix, the outer setting of single bit matrix 3 has step 4, and the inner side and the outside that are positioned at each bit matrix 3 are all provided with a plurality of alloy blocks 2.The design of alloy block 2 has improved the intensity of drill bit.
Cylindrical steel body 1 bottom even is arranged at intervals with ten bit matrixes 3.
In actual use procedure, by being evenly arranged at intervals with bit matrix 3, drill bit creeps into the phenomenon that sideslip occurs Shi Buhui, 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.
