Detailed description of the invention
Referring to Fig. 1 to Fig. 2, the present invention provides a kind of combination rock bit 100, and it includes connecting screw rod the 1st,
Bit leg 2 and gear wheel 3, described connection screw rod 1 has the connection end 11 of the drilling rod for rig and for described bit leg
2 installation ends 12 installed, described bit leg 2 one end is installed on described connection screw rod 1, and the other end supplies described
Gear wheel 3 is installed.
Referring to Fig. 1 to Fig. 6, the quantity of described bit leg 2 and described gear wheel 3 is three, described connection
Three grooves 121 installed for described bit leg 2 are uniformly offered on the outer peripheral edge of the installation end 12 of screw rod 1,
Certainly in other embodiments, the quantity of described bit leg the 2nd, described gear wheel 3 and described groove 121 can be two
Or more and concrete depending on actual demand, such as accompanying drawing 9, the quantity of described bit leg 2 and described gear wheel 3 is equal
It is four, the outer peripheral edge of the installation end 12 of described connection screw rod 1 uniformly offers and installs for described bit leg 2
Four grooves 121.Described bit leg 2 is connected with by welding is fixing with described installation groove 121, described
Bit leg 2 has the first end 21 matching with described groove 121 and the second end installed for described gear wheel
22, the end face of described second end 22 is inclined to set and abuts for described gear wheel 3, and which is provided with described
The auxiliary section 23 that gear wheel 3 matches, thereby, described gear wheel 3 can be advantageously mounted on described bit leg 2,
It is formed with stop section 24, when described bit leg 2 is installed on institute between described first end 21 and described second end 22
When stating on connection screw rod 1, described first end 21 matches with described groove 121, described stop section 24 and
The end face of installation end 12 of described connection screw rod 1 abuts against, it is thus possible to ensure described gear wheel 3 in described
Connect the uniformity in the axial direction of screw rod 1.
Refer to Fig. 7 to Fig. 9, when the gap-ratio of the gear wheel of rock bit is bigger, such as 310 specifications
Gap between the gear wheel of rock bit is just bigger, now, for more preferable fractured rock, described connection spiral shell
The end face center of the installation end 12 of bar 1 is provided with scraping drill bit 4, and described scraping drill bit 4 is positioned at described
Between bit leg 2, described scraping drill bit 4 one end is installed on the installation of described connection screw rod 1 by being welded and fixed
On end 12.
Based on the disclosure of technique scheme, the present invention provides a kind of combination rock bit 100 to have following to be had
Benefit effect:
The present invention open one combination rock bit 100, it includes connecting screw rod the 1st, bit leg 2 groups and gear wheel 3
Group, described connection screw rod 1 has connecting end 11 and supplying the installation of described bit leg 2 installation of the drilling rod for rig
End 12, described bit leg 2 one end is installed on described connection screw rod 1, and its other end is installed for described gear wheel 3；
Its connection screw rod 1 and bit leg 2 use split-type design manufacture, and then, same connection screw rod 1 from different
Bit leg 2 and gear wheel can form the rock bit of different size, and identical connection screw rod the 1st, bit leg 2
And between gear wheel, use different connecting portions, it is also possible to rock bit (such as 250 rule of composition different size
It is basic that the 2nd, the gear wheel of the rock bit of the rock bit of lattice and 310 specifications the 3rd, bit leg connects screw rod 1 these three
The specification of assembly is the same, different with welding position owing to connecting, and constitutes the tooth of two kinds of diameter specifications
Wheel drill bit, as a same reason, with this three kinds of constant basic bodies, changes and connects and welding position, it is possible to group
The rock bit of synthesis multiple diameter specification.) thus, under conditions of manufacturing specification rock bit as much,
The species of required connection screw rod the 1st, bit leg 2 and gear wheel is less, so that the complexity of process equipment is more
Low, thus, reduce manufacture difficulty and strengthen the versatility of the parts combining rock bit 100.
Above in conjunction with accompanying drawing, exemplary description is carried out to the present invention, it is clear that the realization of the present invention is not by upper
State the restriction of mode, as long as have employed the various improvement that technical solution of the present invention is carried out or not improved by this
The design of invention and technical scheme are directly used in other occasions, all within the scope of the present invention.
