Abstract
The utility model provides a drilling head, wherein the lower end of a drill bit pipe is connected with a conical rotary drilling device through a support bar, wherein the rotary drilling device is provided with a plurality of rotary drilling blades on the outer end of a conical cross bar which is connected. The drilling head can be connected on a drilling pipe of a drilling machine through adopting a flange or a rotary connecting mode, which is used as a drilling bit to be used by an underground pipe-driving well, and the rotary drilling blades which are mounted can be engaged with a rotary plate on an original drilling bit to form a high-speed drilling-down effect, and the well drilling speed can improve more than 10 times. The utility model has the advantages of saving energy, saving labor, fast speed and excellent effect.
Description
Technical field
The utility model relates to a kind of drill bit of beating the buried pipe well, a kind of specifically drilling well head that is provided with the tapered rotary drill device of arch.
Background technology
The rig of beating the buried pipe well that uses now bores sand, be that several blades are set around the leading portion of drill bit pipe, and a tapered drill bit is housed on the top, during use, mainly rely on the blade rotation to cooperate tapered drill bit to bore downwards, because tapered drill bit lacks screw action, can only by around blade and rig pressurization could advance downwards, have that speed is slow, weak effect and a big problem of power consumption, particularly under the situation that meets with underground stone, speed is slower, and energy consumption is also bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of drilling well head, has the characteristics of fast, the effective and lowering energy-saving of speed.
The utility model comprises drill bit pipe and several blades that are provided with thereof all around, and the technical scheme that is adopted is: the lower end at the drill bit pipe is connected with a tapered rotary drill device of arch by pole.
The pole of described drill bit pipe lower end is two, divides the corresponding outer wall that is located at drill bit pipe both sides in vertical direction.
The tapered rotary drill device of described arch is to be provided with several rotary drill blades in the outer end of the tapered cross bar of arch.
Described several rotary drill blades arch tapered cross bar outer end with encircle tapered in the middle of the place be to two side ends and be equal to that number average is even to be arranged.
The tapered cross bar of described arch is to be equal to the even rotary drill blade branch both sides relative tilt setting of arranging of number average to two side ends in the middle of the arch awl.
When the utility model uses, can adopt flange or the mode of spinning to be connected on the drilling pipe of rig, several rotary drill blades of being adorned are under the rig effect, can outward winding at a high speed earth and stone, compared with prior art, can improve work efficiency more than 10 times, have energy and labour saving, fast, the effective distinguishing feature of speed.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 looks up structural representation for the utility model.
The specific embodiment
Shown in the accompanying drawing embodiment: the lower end at drill bit pipe 1 is connected with a tapered rotary drill device of arch by pole 2, the pole 2 of drill bit pipe 1 lower end is two, divide the corresponding outer wall that is located at drill bit pipe 1 both sides in vertical direction, encircleing tapered rotary drill device is to be provided with several rotary drill blades 4 in the outer end of the tapered cross bar 3 of arch.Several rotary drill blades 4 arch tapered cross bar 3 outer ends with the arch awl in the middle of the place be to two side ends and be equal to that number average is even to be arranged.Encircle tapered cross bar 3 and be equal to even 4 fens both sides of the rotary drill blade relative tilt setting of arranging of number average to two side ends to encircle tapered centre.
When the utility model uses, dock with the drilling pipe of rig, also can adopt spiral interface to be screwed on the drilling pipe, specifically can be provided with according to the drilling pipe virtual condition of rig at the upper end of drill bit pipe 1 adjunction flange.
