Abstract
The invention relates to a deflection prevention drill bit for drilling. The deflection prevention drill bit comprises a hollow cylindrical steel body, drill bit moulds are evenly arranged at the bottom of the cylindrical steel body at intervals, each drill bit mould is of a turbination structure, a step is arranged outside each drill bit mould, and a plurality of alloy blocks are arranged on the inner side and the outer side of each drill bit mould. The deflection prevention drill bit is compact and reasonable in structure and convenient to manufacture; through the drill bit moulds evenly arranged at intervals, the phenomenon of deflection of the drill bit in the process of drilling can be effectively prevented, hole drilling quality can be improved, and work efficiency can be improved.
Description
Technical field
The present invention 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 ， 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, the phenomenon of sideslip easily occurs, and cannot feel relieved, and has brought inconvenience to boring work, affects probing work.
Summary of the invention
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 solution adopted in the present invention 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.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, 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 invention.
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 invention 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.
Bit matrix 3 is welded in the bottom of cylindrical steel body 1.
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 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.
