Specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1, the embodiment of the present invention provides a kind of side flip alloy bit, and it includes：
Joint 1, the joint 1 is provided with the interface 10 of the drilling rod grafting for drilling tool；
Base 2, the base 2 is sheathed on the one end of the joint 1 away from the interface 10, and the base 2 is near described
One end of joint 1 is embedded with an adapter 20, and the adapter 20 is embedded in the joint 1 and limits the relative of the joint 1 and base 2
Rotate, and the base 2 is additionally provided with a groove 21 set along the length direction of the base 2；
Parent plate 3, described matrix plate 3 is plugged in the groove 21, and the side wall of described matrix plate 3 is provided with multiple contiguous blocks
A carbide button 31 is installed with 30, and each contiguous block 30；
Meanwhile, the joint 1 and base 2 are hollow structure, and the joint 1 and base 2 are collectively forming a runner 4,
And described matrix plate 3 is provided with the aperture of door 5 being connected with the runner 4.
Compared with prior art, side flip alloy bit of the invention is set and bit direction by drill end
Consistent contiguous block and carbide button, can effectively drill hard layer, weathered layer and the lithosphere of general bit bore inefficiency, carry
The drilling efficiency and pile efficiency of drill bit are risen.
Side flip alloy bit of the invention may also include a pair of the door closures 6 for being relatively arranged on the both sides of described matrix plate 3, institute
State the top of door closure 6 and be provided with a connection member 7, the connection member 7 is connected with the bearing pin of the base 2.Door closure 6 is in drilling process
Because rock and soil pressure effect holding is closed, when extracting out because air pressure effect is opened, the UNICOM of runner 4 is drilled, be easy to
Implement cementing operations.
The masked area of door closure 6 can be set to be adapted with the area of the aperture of door 5.It is too short, operation of drilling cannot be ensured
When door closure 6 aperture of door 5 is covered, is prevented from getting out sand and is poured into runner 4, long, in drilling operation, door closure 6 is easily squeezed generation
Deformation bending.
The gear mud bar 8 that one circle is adapted with the masked area of the door closure 6 can be set on the edge of the aperture of door 5.It is this to set
The cutting force that is subject to of door closure 6 when on the one hand can avoid reducing bore operation is put, prevents door closure 6 to be squeezed the bending that deforms；
On the other hand the closed performance of aperture of door 5 can further be strengthened, it is to avoid sand pours in down a chimney air stream enter runner 4.
Gear mud bar 8 may be provided on parent plate 3, while can well providing the closed performance of aperture of door 5, drilled
In operation loose shift is difficult during the extruding force of ground.
Door closure 6 can be around the bearing pin of the connection member 7 in the outer rotation of the base 2, when the door closure 6 is closed, with the bottom
2 table co-planars of seat.This set shortens the length of door closure 6 in existing apparatus, it is to avoid door closure in existing band door closure drill bit
Masking aperture of door 5 cannot be brought into close contact, the defect of bending deformation easily occurs.
Can be by the setting in opposite direction of 3 top and bottom carbide button of parent plate 31.Make carbide button 31 located at contiguous block 30 and brill
Bar angular velocity of rotation direction identical side, carbide button 31 and the contact area of rock-soil layer, strengthen drill bit during increase bore operation
Drilling efficiency, reduces the inessential abrasion to drill bit.
Can there will be an angle for 30-60 degree between the setting direction of contiguous block 30 and the length direction of described matrix plate 3, increase is bored
Carbide button 31 and the contact area of rock-soil layer, strengthen bit bore efficiency during the operation of hole, reduce the inessential abrasion to drill bit.
Tooth 9 can be also threaded on side flip alloy bit of the present invention, the thread 9 is twist fixed on described
On the outer wall of joint 1.
Between the joint 1, base 2 and the adapter 20；Between the base 2, contiguous block 30 and described matrix plate 3；
Can be used between the carbide button 31 and the contiguous block 30 and be welded and fixed.Stable connection, can tolerate high temperature and easy to disassemble
Change.
The brazing of the carbide button 31 can be fixed on the contiguous block 4.Brazing bonding strength is high, and can bear highest
Temperature extremes operating mode, is easy to strengthen drilling life of bit.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as protection of the invention
Within the scope of.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
