Background technology
When geological research such as geological prospecting, oil drilling and exploitation; Need carry out drill-well operation to ground; And the geological conditions of various places differs; The geological conditions on the same face of land also possibly condition of different occur owing to the difference of structure, need provide the drill bit that can adapt to various geological conditions to carry out drill-well operation thus.
At present, the PDC drill bit is the drill bit commonly used that current geological drilling is used, because this PDC drill bit has characteristics such as high-wearing feature, high impact-resistant, anti-oblique, anti-mud drum, high rotating speed; Therefore, in drilling process, the PDC drill bit has high-performance advantages such as high drilling speed, low the pressure of the drill, high drilling depth; It can reduce the geological drilling cost greatly in the application of drilling process, accelerates bit speed; The advantage of PDC drill bit self and characteristics make it can adapt to most geological conditions just.
And owing to during geological drilling, normally carry out the drilling condition very severe in the open air; Requirement to the PDC drill bit is very high; In order to guarantee the use of PDC drill bit, himself quality is that to guarantee that the PDC drill bit uses basic, though the PDC drill quality is improving constantly; But inevitably drill bit damage in use; And occur that cutting damages when to medium ground, using the PDC drill bit and PDC can't in time change soft, and or when the bit diameter size is bigger, cause the difficulty changed, cause for the field work of PDC and bring certain degree of difficulty.
And in order to overcome said defective, the designer of the utility model has effectively developed a kind of portable drill bit.
Summary of the invention
The purpose of the utility model is to provide a kind of portable drill bit, and it is simple in structure, and is easy-to-use, can realize being convenient for carrying and change fast, makes that drill bit can in time obtain changing and safeguarding, has prolonged the application life of drill bit.
For realizing said purpose, the utility model discloses a kind of portable drill bit, this portable drill bit comprises drill body 1, at least two chip areas 2, at least two wings 3, a plurality of main cutting tooth 4 and a plurality of nozzles 5; It is characterized in that:
Said drill body 1 is cylindrical, and said at least two wings 3 are arranged at the cutting end of drill body 1, and said chip area 2 is between wing 3, along being arranged at intervals with a plurality of main cutting teeth 4 on the cutting edge of each wing 3.
Wherein, corresponding each main cutting tooth 4 is provided with a cutting teeth tooth cave 6 on the said wing 3, and said cutting teeth tooth cave 6 is a groove-like, and said main cutting tooth 4 is fixed in the said cutting teeth tooth cave 6 through trip bolt 7.
Wherein, Said cutting teeth tooth cave 6 is provided with screwed hole; Said main cutting tooth 4 is provided with fixed via, said trip bolt 7 pass on the said main cutting tooth 4 said fixed via with said cutting teeth tooth cave 6 on the engagement of said screwed hole so that said main cutting tooth 4 is fixed in the said cutting teeth tooth cave 6.
Wherein, said trip bolt 7 comprises head of screw and thread segment, and the said fixed via of said main cutting tooth 4 is provided with the ladder section with the said head of screw form fit of said trip bolt 7.
Wherein, said a plurality of nozzle 5 is arranged at the cutting end of said drill body 1.
Through said structure, the portable drill bit of the utility model can be realized being convenient for carrying and change fast, makes that drill bit can in time obtain changing and safeguarding, has prolonged the application life of drill bit.
The detailed content of the utility model can through after explanation and the institute's accompanying drawing stated obtain.
