Abstract
The present invention relates to the oil hollow drill being easy to dust lead, including cylindrical main rod body, through hole is offered in main rod body, main rod body outer wall is arranged with cylinder, cylinder outer wall offers multiple groove, it is equipped with groove I in each groove, groove I is identical with the diameter of the cross section of groove, the distance of the opening on groove I top is less than the diameter of groove I cross section, groove I all protrudes from groove axial, horizontal, the bottom of groove I is provided with ring baffle, and ring baffle is axially provided with chip pocket in groove I.The present invention is by having dust lead and admittedly consider the groove I of function to be worth doing arranging, it is possible to the scrap well collected and produce during fixing drilling well, overcomes the existing drilling rod can not the chip removal problem that cause blocking in well.
Description
Technical field
The present invention relates to field of petroleum machinery, in particular it relates to a kind of oil hollow drill being easy to dust lead.
Background technology
Hollow drill is when degree of depth drilling well, the drilling well Excretas such as a lot of soil bits, aggregate chips and mud can be produced in well, if these chip removal things can not in time, well discharge, can cause that in well, Excreta is piled up, the destruction that drill bit, drilling rod etc. are not only caused by the blocking in well, but also there will be the problems such as drill bit is stuck, drilling rod is immovable, not only rig is caused destruction but also have impact on the work efficiency of rig, be unfavorable for practicality and development.
Summary of the invention
The technical problem to be solved is to provide a kind of oil hollow drill being easy to dust lead, to overcome existing drilling rod chip removal can not cause the problem of blocking in well.
This invention address that the problems referred to above be the technical scheme is that and be easy to the oil hollow drill of dust lead, including cylindrical main rod body, through hole is offered in main rod body, main rod body outer wall is arranged with cylinder, cylinder outer wall offers multiple groove, it is equipped with groove I in each groove, the cross-sectional outer diameter of groove I is identical with the cross-sectional inner diameter of groove, the distance of the opening on groove I top is less than the diameter of groove I cross section, groove I is axially, laterally all protrude from groove, the bottom of groove I is provided with ring baffle, ring baffle is axially provided with chip pocket in groove I.Cylinder the stability that can strengthen hollow drill is set, it is easy to arrange groove I on drilling rod, arranging on the one hand owing to it is axially of groove I, laterally all protrude from groove, groove I is made to carry out second time drilling well, improve smoothness and the flatness of the borehole wall, Reinforcing Shaft, on the other hand, the soil bits that groove I produces when can collect drilling well, some scrap of aggregate chips etc., the scrap being will not block drilling well, guarantee being smoothed out of drilling well, simultaneously, ring baffle it is provided with in groove I, this ring baffle and groove I have identical radian, and in ring baffle, it is provided with chip pocket, ring baffle and chip pocket with the use of can well the scrap collected is fixed in groove I, improve effect and the stability of groove I dust lead, the present invention is by having dust lead in setting and admittedly consider the groove I of function to be worth doing, the scrap produced when can be good at collection and fixing drilling well, overcome existing drilling rod chip removal can not cause the problem of blocking in well.
Further, one end that main rod body coordinates with ring baffle is provided with locating shaft, and described through hole runs through locating shaft.Oil drill rocker and connector are positioned by oil drill rocker locating shaft when connecting, it is prevented that oil drill rocker occurs, it is ensured that the guidance quality of oil drill rocker and connector.
Further, the length of locating shaft is 60-80mm.Locating shaft mainly plays a good location and guide effect when connecting, the problem considering locating shaft location and guiding intensity and material, the length of locating shaft is set to 60-80mm, while minimal material, strengthens its location and guiding intensity in use.
Further, groove I is evenly arranged with 6.Groove I offers the structural stability having influence on cylinder too much, and dust lead effect is bad very little, and the scrap in well is derived by 6 groove I simultaneously, improves work efficiency while guaranteeing cylinder stability.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by having dust lead and admittedly consider the groove I of function to be worth doing arranging, it is possible to the scrap well collected and produce during fixing drilling well, overcomes existing drilling rod chip removal can not cause the problem of blocking in well.
2, the present invention is by arranging locating shaft, it is ensured that the guidance quality of oil drill rocker and connector.
Accompanying drawing explanation
Fig. 1 is the structural representation of hollow drill.
Labelling and corresponding parts title in accompanying drawing:
1 through hole；2 locating shafts；3 main rod body；4 ring baffles；5 groove I；6 cylinders.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, detailed description further is done in invention, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figure 1, it is easy to the oil hollow drill of dust lead, including cylindrical main rod body 3, through hole 1 is offered in main rod body 3, main rod body 3 outer wall is arranged with cylinder 6, cylinder 6 outer wall offers 5 grooves, groove I 5 it is equipped with in each groove, the cross-sectional outer diameter of groove I 5 is identical with the cross-sectional inner diameter of groove, the distance of the opening on groove I 5 top is less than the diameter of groove I 5 cross section, groove I 5 is axially, laterally all protrude from groove, the bottom of groove I 5 is provided with ring baffle 4, ring baffle 4 is axially provided with chip pocket in groove I 5, one end that main rod body 3 coordinates with ring baffle 4 is provided with locating shaft 2, the length of locating shaft 2 sets son as 60-80mm, described through hole 1 runs through locating shaft 2.
Cylinder 3 the stability that can strengthen hollow drill is set, it is easy on drilling rod, arrange groove I 5, arranging on the one hand owing to it is axially of groove I 5, laterally all protrude from groove, groove I 5 is made to carry out second time drilling well, improve smoothness and the flatness of the borehole wall, Reinforcing Shaft, on the other hand, the soil bits that groove I 5 produces when can collect drilling well, some scrap of aggregate chips etc., the scrap being will not block drilling well, guarantee being smoothed out of drilling well, simultaneously, ring baffle 4 it is provided with in groove I 5, this ring baffle 4 has identical radian with groove I 5, and it is provided with chip pocket in ring baffle 4, ring baffle 4 and chip pocket with the use of can well the scrap collected is fixed in groove I 5, improve effect and the stability of groove I 5 dust lead；Oil drill rocker and connector are positioned by oil drill rocker locating shaft 2 when connecting, it is prevented that oil drill rocker occurs, it is ensured that the guidance quality of oil drill rocker and connector.
As it has been described above, the present invention can be realized preferably.
