Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only of the invention
A part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Referring to Fig. 3 and Fig. 4, stake top drilling machine drilling tool of the invention includes: knife rest 11, cutterhead 12, disk cutter 13, landwaste receipts
Acquisition means 14, chip-removal hole 15.Disk cutter 13 is arranged on cutterhead 12 along a plurality of equally distributed Archimedes spiral, and landwaste is received
Above-mentioned a plurality of Archimedes spiral is arranged between any two in acquisition means 14, and the tail of landwaste collection device 14 is arranged in chip-removal hole 15
Portion is provided with main chip-removal hole 16 and channel of chip removal 17 in knife rest 11, and chip-removal hole 15 is connected to main chip-removal hole via channel of chip removal 17
16.In addition, the cutting operation section of stake top drilling machine drilling tool of the invention is " W " shape, i.e., it is specific as shown in figure 3, disk cutter 13
It is arranged by high and low on cutterhead 12 along short transverse, so that disk cutter 13 is relative to bottom rock layer when wellbore construction
The cutting operation section of B is substantially in " W " shape.
As a kind of specific embodiment, as shown in figure 4, disk cutter 13 can along three Archimedes spiral a1, a2,
A3 is arranged on cutterhead 12, is provided with multiple disk cutters 13 along every Archimedes spiral a1, a2, a3；Archimedes's spiral shell
Landwaste receipts are provided between line a1 and a2, between Archimedes spiral a2 and a3 and between Archimedes spiral a3 and a1
Acquisition means 14 amount to three groups of landwaste collection devices 14.
Preferably, landwaste collection device 14 is that the landwaste of Archimedes spiral shape collects conduit, in stake top of the invention
As when the direction C rotates and carries out wellbore construction along Fig. 4, disk cutter 13 cuts bottom rock layer B on drilling machine drilling tool edge, with
