Embodiment
Below in conjunction with the accompanying drawing 1-9 of the present invention, technical scheme is clearly and completely described, it is clear that
Described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the implementation in the present invention
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of protection of the invention.
In an embodiment of the invention, as Figure 1-5, a kind of coring bit, including：Drill bit 10, is being bored
Jump ring chamber 21 is offered inside crown 10, and jump ring 2 is provided with inside jump ring chamber 21, the bottom of drill bit 10 is in tapered.
Jump ring 2 is provided with inside jump ring chamber 21, sampling operation of the coring bit to rock core is met.The bottom of drill bit 10 is in cone
Type, tapered structure has been more convenient the positioning work of drill bit, and a tapered face can be formed on bottom of the drill bit in drilling formation pore,
Centering steady drill bit drilling tool is played not swing.
As Figure 1-5, in order to improve the intensity of drill bit 10, cutting is fixedly connected with the cutting face of drill bit 10
Tooth 1.In use, cutting tooth 1 is primarily subjected to the friction between rock and impact, extends the use of drill bit
Life-span.
As shown in figs. 4-7, in order to be further ensured that the reasonable in design of cutting tooth 1, using PDC diamond compacts.Cutting
Tooth 1 includes：Alloy basic unit 11 and diamond layer 12；Alloy basic unit 11 is fixedly connected with diamond layer 12, and diamond layer 12 is being bored
The cutting edge side of crown 10, alloy basic unit 11 fits fixation with drill bit 10.Soft medium ground (6 grades of rocks in
Layer) there are high stock-removing efficiency, wearability and temperature tolerance, can fast drilling, raising operating efficiency.
As shown in fig. 6-7, in order to ensure that cutting tooth 1 is fixed on behind the end of drill bit 10, drill bit 10 is in tapered knot
Structure, the secondary cutting face of cutting tooth 1 is obliquely installed from high to low from the center of drill bit 10 to marginal position, further ensured
The tapered structure of drill bit 10.
As shown in figure 9, rock core is during coring bit is stretched into for convenience, rock core is easier to strut jump ring 2.By jump ring
2 obtain the design of inner chamber downside in horn-like.Rock core is stretched into from horn-like opening end, gradually struts jump ring 2, is facilitated rock core and is stretched into
Drill bit internal.
As shown in figure 8, the inner chamber of jump ring 2 is in petal-shaped, thread groove 22 is opened up in the inwall of jump ring 2.Preferably plum blossom flap
Structure design, easily opens when entering for core in jump ring 2, and reduces friction between jump ring 2 and the surface of core two, it is ensured that rock
Core diameter size and core-taking rate.
As Figure 1-3, required to ensure that the length of coring bit is met, in addition to：Under screw rod 20, screw rod 20
End opens up external screw thread, and drill bit 10 is fixedly connected by opening up internal thread with the external screw thread of screw rod.And screw rod 20
Stretched into from the upper end of drill bit 10, the bottom of screw rod 20 and either flush on jump ring chamber 21.Jump ring 2 has been further facilitated to insert
Inside jump ring chamber 21, and when in use, position-limiting action is played in the bottom of screw rod 20 to jump ring 2, has further facilitated 2 pairs of jump ring
The sampling of rock core.
As Figure 1-5, in order to solve drill bit in drilling formation pore, enable drill bit that there is high stock-removing efficiency and row's powder
Power, is easy to outside rock dust and the smooth tap of bottom hole heat, does not cause the burning of bits.Side wall and the side of drill bit 10 in screw rod 20
Wall opens up helicla flute 3.
As Figure 1-3, connection for convenience between screw rod 20 and drilling rod, the upper interior of screw rod 10 or outside
Provided with drilling rod connection screw thread 4, facilitate the connection between drilling rod connection screw thread 4 and drilling rod.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
