Description

Technical Field

[0001] This utility model relates to the field of reinforced drill bit technology, specifically a heat-resistant and wear-resistant integrated reinforced drill bit. Background Technology

[0002] In the drilling process, the drill bit is the primary tool for breaking rocks, and the wellbore is formed by the drill bit breaking rocks. The quality of wellbore formation and the time taken to form depend not only on the characteristics of the rock formation being drilled and the performance of the drill bit itself, but also, and perhaps more importantly, on the degree of compatibility between the drill bit and the formation. Appropriate drill bit selection plays a crucial role in improving drilling speed and reducing overall drilling costs.

[0003] After prolonged use, existing drill bits typically require disassembly for cleaning and replacement. However, current drill bit structures are often complex, making disassembly cumbersome and increasing the time required for workers. This hinders the rapid disassembly process and consequently affects the efficiency of cleaning and replacing drill bits. Utility Model Content

The rotating shaft 3 is the main structure of the drill bit, that is, the drill bit is rotated by the rotating shaft 3. Drill teeth 11 are provided at the bottom of the drill bit body 1, and the drill teeth 11 are the bottom structure of the drill bit body 1. The outer side of the drill teeth 11 is inclined, thereby ensuring the wear resistance of the drill bit. A spherical block 12 is provided on the outer side of the drill bit body 1. The spherical block 12 is hemispherical, that is, in When the drill bit is in use, the outer spherical block 12 also provides good wear resistance, which can effectively prevent the drill bit from being damaged. A through-hole 13 is provided on the top of the spherical block 12, which extends to the inside of the drill bit body 1. The through-hole 13 facilitates the cleaning of dirt and other impurities on the inside of the drill bit body 1. A drill bit mounting seat 4 is provided at the bottom of the rotating shaft 3. The drill bit mounting seat 4 is a mounting structure used to install the drill bit body 1. The rotating shaft 3 drives the drill bit mounting seat 4 to rotate, thereby driving the drill bit body 1 to rotate.

[0022] The drill bit mounting base 4 has an installation groove 41 on its inner side, which is an installation structure. The drill bit body 1 has an installation post 2 on its top, which is also an installation structure. The installation post 2 is movably installed in the installation groove 41, that is, the installation groove 41 is connected to the installation post 2, so that the drill bit body 1 is installed in the drill bit mounting base 4. A limit strip 21 is provided on the outer side of the installation post 2, and a limit rail 42 is provided on the inner side of the installation groove 41. The limit strip 21 and the limit rail 42 are slidably connected, that is, the limit rail 42 limits the limit strip 21, so that the installation post 2 is slidably installed in the installation groove 41 and cannot be rotated. A connection port 22 is provided on the outer side of the top of the drill bit body 1, and a connecting bolt 43 is provided on the outer side of the bottom of the drill bit mounting base 4. The connecting bolt 43 is slidably connected to the connection port 22. When the installation post 2 is installed in the installation groove 41, the connecting bolt 43 is connected to the connection port 22.

[0023] A semi-circular groove 31 is provided on the upper outer side of the drill bit mounting base 4.

That is, by rotating the fixing bolt 32 in the semi-circular groove 31, the movable bolt 33 rotates in the movable opening 44, which drives the bolt 34 to rotate, thereby connecting the bolt 34 to the threaded opening 23, thus fixing the mounting post 2.

[0024] The working principle of this utility model is as follows: the mounting post 2 connects to the mounting groove 41, thereby allowing the drill bit body 1 to be installed in the drill bit mounting seat 4. The limiting rail 42 limits the limiting strip 21, allowing the mounting post 2 to slide in the mounting groove 41 and preventing it from rotating. By rotating the fixing bolt 32 in the semi-circular groove 31, the movable bolt 33 rotates in the movable opening 44, driving the bolt 34 to rotate, thereby connecting the bolt 34 to the threaded opening 23, thus fixing the mounting post 2. After the mounting post 2 is installed in the mounting groove 41, the connecting bolt 43 connects to the connecting opening 22, making the drill bit installation more stable. When the drill bit is in use, the rotating shaft 3 drives the drill bit mounting seat 4 to rotate, thereby driving the drill bit body 1 to rotate. The outer side of the drill teeth 11 is inclined, thus ensuring the wear resistance of the drill bit. The outer spherical block 12 also provides good wear resistance, effectively preventing damage to the drill bit. The through-hole 13 facilitates the cleaning of dirt and other impurities on the inner side of the drill bit body 1.
