Abstract
The invention relates to a zigzag tooth-shaped drill bit for exploratory drilling. The zigzag tooth-shaped drill bit comprises a hollow cylindrical steel body. Drill bit green bodies are evenly arranged at the bottom of the hollow cylindrical steel body at intervals. The drill bit green bodies comprise first drill bit green bodies and second drill bit green bodies. The first drill bit green bodies and the second drill bit green bodies are arranged at the bottom of the cylindrical steel body in a staggered mode. The first drill bit green bodies and the second drill bit green bodies are of tooth-shaped structures. The zigzag tooth-shaped drill bit is compact and reasonable in structure and convenient to manufacture. The drill bit green bodies are evenly arranged at intervals and of the tooth-shaped structures which are arranged in the staggered mode. The drilling speed and the working efficiency are improved.
Description
Technical field
The present invention relates to geological prospecting equipment technical field, staggered jagged bit for especially a kind of probing.
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 is in drilling process, and its rate of penetration is slower, and inefficiency affects probing work.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides staggered jagged bit for a kind of probing rational in infrastructure, thereby improves rate of penetration, increases work efficiency.
The technical solution adopted in the present invention is as follows:
Staggered jagged bit for a kind of probing, comprise into hollow cylindrical steel body, described cylindrical steel body bottom even is arranged at intervals with bit matrix, described bit matrix is divided into the first bit matrix and the second bit matrix, described the first bit matrix and the second bit matrix are crisscross arranged in cylindrical steel body bottom, and described the first bit matrix all becomes tooth-shape structure with the second bit matrix.
Further improvement as technique scheme:
Described bit matrix is welded in the bottom of cylindrical steel body.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy to make, by even spaced bit matrix, bit matrix adopts the tooth-shape structure being crisscross arranged, and improves rate of penetration, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, cylindrical steel body; 2, the first bit matrix; 3, the second 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, staggered jagged bit for the probing of the present embodiment, comprise into hollow cylindrical steel body 1, cylindrical steel body 1 bottom even is arranged at intervals with bit matrix, bit matrix is divided into the first bit matrix 2 and the second bit matrix 3, the first bit matrix 2 and the second bit matrix 3 are crisscross arranged in cylindrical steel body 1 bottom, and the first bit matrix 2 all becomes tooth-shape structure with the second bit matrix 3.
Bit matrix is welded in the bottom of cylindrical steel body 1.
In actual use procedure, by even interleaved, be provided with bit matrix, drill bit rate of penetration is fast, and operating efficiency is high, 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 (2)
1. staggered jagged bit for a probing, it is characterized in that: comprise into hollow cylindrical steel body (1), described cylindrical steel body (1) bottom even is arranged at intervals with bit matrix, described bit matrix is divided into the first bit matrix (2) and the second bit matrix (3), described the first bit matrix (2) and the second bit matrix (3) are crisscross arranged in cylindrical steel body (1) bottom, and described the first bit matrix (2) all becomes tooth-shape structure with the second bit matrix (3).
2. staggered jagged bit for probing as claimed in claim 1, is characterized in that: described bit matrix is welded in the bottom of cylindrical steel body (1).
