Abstract

Both there is drilling function the utility model relates to a kind of, the drilling formula variable diameter sizing drill hammer that there is reaming again, determine hole aperture function, including drill hammer, boring bar head is embedded with alloy bit, and drilling rod shaft cuts portion by variable diameter from bottom to top and the sizing portion of cutting is constituted;The alloy bit diameter is greater than drilling rod shaft diameter;Interruption is gradually increased from bottom to top embedded in the diameter for the cutter tip that drilling rod shaft variable diameter cuts portion;The sizing portion of cutting from bottom to top by be interrupted cut on the drilling rod shaft head constitute and cut head diameter it is identical.Advantage: first is that having started drill hammer hole structure, sinker bar intensity is enhanced;Second is that keeping hole wall more smooth, borehole accuracy is higher, more efficient using expanding mode pore-forming is cut.

Description

A kind of drilling formula variable diameter sizing drill hammer
Technical field
Not only there is drilling function, but also the drilling formula variable diameter for having reaming, determining hole aperture function the utility model relates to a kind of Sizing drill hammer belongs to drill hammer manufacturing field.
Background technique
All first patent CN206066363U of the applicant, title " second level variable diameter drill hammer ", including impact drill Head, it is characterized in that: the diameter of the drill hammer drilling rod becomes larger by starting point, the spiral being distributed on variable diameter drilling rod Chip space blade is embedded with expanding alloy head.
Summary of the invention
Purpose of design: on the basis of in the introduction, designing one kind not only has drilling function, but also has reaming, determines hole The drilling formula variable diameter sizing drill hammer of aperture function.
Design scheme: in order to realize above-mentioned purpose of design.In structure design, boring bar head is embedded with alloy to the utility model Drill bit and drilling rod shaft cuts the design that portion and the sizing portion of cutting are constituted by variable diameter from bottom to top, is the main skill of the utility model Art feature.The purpose of this design is: drilling rod shaft is without opening spiral shell since alloy bit is on the shaft of drilling rod Chip space is revolved, and then improves the intensity of drilling rod shaft;Secondly as varying diameter portion is from bottom to top gradually expanded and embedded in drilling rod Alloy cutting head on shaft can cut the hole wall that alloy bit drills out under the drive of impact drill, expand it gradually Cut sizing (aperture) greatly and by sizing cutting portion;Third is that due to the cutter tip that is located on drilling rod shaft from and and it is upper between abscission ring To distribution, the spacing between cutter tip and cutter tip then constitutes drilling cuttings, passage of cuttings, which can be quick Drilling cuttings, chip material are discharged on ground.
Technical solution: a kind of drilling formula variable diameter sizing drill hammer, including drill hammer, boring bar head are bored embedded with alloy Head, drilling rod shaft cuts portion by variable diameter from bottom to top and the sizing portion of cutting is constituted;The alloy bit diameter is greater than drilling rod shaft Diameter;Interruption is gradually increased from bottom to top embedded in the diameter for the cutter tip that drilling rod shaft variable diameter cuts portion;The sizing portion of cutting is certainly It is lower and it is upper be embedded in by interruption cut on drilling rod shaft head constitute and cut head diameter it is identical.
The utility model compared with the background art, first is that having started drill hammer hole structure, it is strong to enhance sinker bar Degree;Second is that keeping hole wall more smooth, borehole accuracy is higher, more efficient using expanding mode pore-forming is cut.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of drilling formula variable diameter sizing drill hammer.
Specific embodiment
Embodiment 1: referring to attached drawing 1.A kind of drilling formula variable diameter sizing drill hammer, including drill hammer 4, boring bar head is embedding There is alloy bit 1, drilling rod shaft cuts portion 2 by variable diameter from bottom to top and sizing cuts portion 3 and constitutes;1 diameter of alloy bit Greater than drilling rod shaft diameter;Interruption is gradually increased from bottom to top embedded in the diameter for the cutter tip that drilling rod shaft variable diameter cuts portion 2; Sizing cut portion 3 from bottom to top by be interrupted cut on the drilling rod shaft head constitute and cut head diameter it is identical.Variable diameter is cut The diameter of the cutter tip in portion 2 refers to the circumferential height and drilling rod shaft that cut head and stretch out drilling rod shaft on drilling rod shaft The sum of diameter.The diameter that sizing cuts the cutter tip in portion 3 refers to that the circumferential head that cuts on drilling rod shaft stretches out drilling rod bar The sum of the height of body and drilling rod shaft diameter.
It is to be understood that: although above-described embodiment contrasts detailed text to the mentality of designing of the utility model Description, but these verbal descriptions only describe the simple text of the utility model mentality of designing, rather than practical new to this It is practical new to each fall within this for the limitation of type mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing In the protection scope of type.
