Description
Technical field
The present invention relates to a kind of for producing the auger in hole at soil or rock.
Background technology
Publication number is the auger of describing in the patent of WO2004/057148, and wherein said annular bit is longer relatively with regard to axially, because the top of annular bit at first is made up of flange, flange comprises by hard metal spike.Except flange, also have a sleeve pipe, at first form groove on the sleeve pipe, when locking onto lead bit, annular bit forms lockhole then.When cutter surpassed the groove be located on the annular bit sleeve pipe and lockhole in the axial direction substantially, cutter was also longer relatively at axial direction.Simultaneously, the body shaft of lead bit is to longer, adjusts the length of required corresponding aperture according to the lockhole of annular bit, and its length is wherein sub-fraction just, be less than its 1/4th.
Summary of the invention
The present invention relates to a kind ofly be made up of lead bit and annular bit for producing the auger in hole at soil or rock, lead bit is used for the drill sampling dotting punch, and annular bit is used for drilling through the periphery in hole.Adjust annular bit according to lead bit in boring procedure, rotated and impact to annular bit by lead bit under the help on described plane, described plane is adjusted between two drill bits and transferring power.Can remove and the installation annular bit along lead bit, and then make the coupling ring that is lockable to annular bit be connected into annular bit with splicing sleeve, sleeve pipe can be pulled in the boring, and is connected on the annular bit under the effect of described coupling ring.
Annular bit is made in short-term as far as possible in the present invention, and the auger on basis of the present invention can be that prior art in the patent of WO2004/057148 is carried out material alteration according to publication number.Characteristics of the present invention be coupling ring along the periphery adjustment of annular bit, workpiece and coupling ring and annular bit lock mutually, at least two both sides of all being located at straight line L, the mid point of straight line through a plane is rotated annular bit.
Advantage of the present invention be the axial length of annular bit because new location and the mounting means of coupling ring is shorter, similarly, the length of coupling ring also correspondingly shortens.But owing to be hard metal material, the column-shaped barrel of annular bit must reach certain thickness, and cylindrical shell on this basis can form groove to connect coupling ring in the periphery of annular bit.In some cases, even a groove has also enough connected coupling ring, but two and plural groove can significantly not increase the length of coupling ring.The best installation of coupling ring is to shrink at the annular bit top and weld.In addition, when annular bit shortened, jet-bedding also can shorter, and flushing flow makes on the pneumatic line of boring throttling takes place, and when throttling reduced gradually, penetration rate was but accelerated.When with coupling ring, as retaining ring for shaft shoulder, when the workpiece of locking arranges according to the lockhole of annular bit related to the present invention, do not consider the lockhole of annular bit, form sufficiently long complete groove as the corresponding surface of retaining ring for shaft shoulder on the coupling ring at annular bit.
Description of drawings
Below in conjunction with accompanying drawing in detail the present invention is described in detail, wherein
Fig. 1 is the sectional view of annular bit of the present invention and coupling ring.
Fig. 2 is the position view of the coupling ring relevant with annular bit.
Fig. 3 is the lateral view of lead bit.
Fig. 4 is the groove schematic diagram of annular bit upper latch notch lock ring.
The specific embodiment
As shown in Figure 1, an annular bit 1 is provided with a column-shaped barrel, and barrel front end comprises a flange 14, and it forms the extension, and the flange axial length is h2, and links to each other with the hard metal spike 13 of flange.Cylindrical shell is located at the rear end from flange 14, is made up of two grooves 12 on the external surface, and coupling ring 2 links to each other with groove, and the overhang 13 that is arranged in coupling ring 2 inner surfaces is located at described groove 12.Equally also be provided with lockhole on the cylindrical shell of annular bit 1, so as with the locking of the corresponding hole site of lead bit.Lockhole is included in the plane that transfers is impacted, the plane 5 on for example plane 4 and 6, and driven rotary.
Can rise in plane 4, plane of constantly rising especially, and cylindrical shell is located at the rear end of annular bit 1 upper flange 14, comprises the corresponding component 12 of overhangs in the coupling ring 2 and the corresponding component 4-6,5,16 and 17 of lead bit 10 Lock Part 7-9.
Described lockhole 4-6 can be used as coupling ring 2 and is located at same position on the cylindrical shell of annular bit 1.Coupling ring 2 axial lengths are h1, and lockhole 4-6 is identical with coupling ring 2 length from the length of cylindrical shell.Therefore, annular bit 1 will shorten in axial run duration.Lockhole 4-6 passes the cylindrical shell of annular bit, thereby the cannelure in the annular bit 12 might not continue to link to each other along cylindrical shell.
Be illustrated in figure 3 as lead bit 10, it is provided with lockhole 7-9 as the corresponding aperture position of annular bit 1 lockhole, compares with the horizontal die head that is used for annular bit, and one of them can shorten the length of lead bit 10 horizontal die heads.
Figure 4 shows that the lockhole of the bayonet socket lock ring of being located in the annular bit.The inner surface of annular bit 1 is provided with vertical channel 18, and end is provided with level trough 17 simultaneously.One male member as tetragonal male member, is located at a side of lead bit, and at first shifts to the end of vertical channel 18, and lead bit when reversing male member is positioned at the plane 5 of level trough 17 ends dorsad and moves, and drives lead bit and rotate to annular bit.Equally, described male member also can impact annular bit by impacting annular bit 1 plane 16 when latched position.In this case, groove 17 and 18 the degree of depth are all less than the wall thickness of annular bit 1.
