Description

Technical Field

[0001] This utility model relates to the field of diamond drill bit technology, specifically a mining combined reaming diamond drill bit. Background Technology

[0002] Drill bits that serve as cutting edges are called diamond drill bits. These are one-piece drill bits with no moving parts, resulting in a simple structure and high strength, wear resistance, and impact resistance. Field experience has proven that diamond drill bits offer advantages such as high drilling speed, high footage, long service life, stable operation, fewer downhole accidents, and good wellbore quality when drilling in soft to medium-hard formations. Diamond drill bits not only have a long service life but are also reusable. Repaired diamond drill bits performed almost as well as brand-new ones, significantly reducing drilling costs.

[0003] Currently, diamond drill bits experience significant wear and tear during high-speed grinding, necessitating timely replacement. However, since existing diamond drill bits are one-piece drill bits, if one drill tooth is damaged, the entire drill bit needs to be replaced, which is not only cumbersome but also results in high replacement costs. Utility Model Content

[0004] The purpose of this invention is to provide a mining-grade combined reaming diamond drill bit to solve the problems mentioned in the background art.

[0010] In a preferred embodiment of this utility model, a first hexagon socket bolt is provided on the outside of the first fixing port. The first hexagon socket bolt passes through the first fixing port and is threadedly connected to the first screw hole.

[0011] In a preferred embodiment of this utility model, the mounting strip is provided with a second fixing port, and the mounting groove is provided with a second threaded port, the second fixing port being connected to the second threaded port.

[0012] In a preferred embodiment of this utility model, a second hexagon socket bolt is provided on the outer side of the second fixing port. The second hexagon socket bolt passes through the second fixing port and is threadedly connected to the second screw hole.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: The drill rod is installed on the mounting piece by connecting the connecting post to the connecting port. The limiting rail limits the limiting strip, allowing the connecting post to slide in the connecting port.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please refer to Figure 1-4 This utility model discloses a mining combined reaming diamond drill bit, including a mounting base 1. The mounting base 1 serves as the mounting structure for the diamond drill bit and is used to install other structures of the diamond drill bit. The bottom of the mounting base 1 is provided with an external thread 11, which is the mounting structure used to install the overall structure. The rotation direction of the diamond drill bit is opposite to the thread direction of the external thread 11. A mounting component 2 is provided above the mounting base 1. The mounting component 2 is the mounting structure. The top of the mounting base 1 has a threaded head 12, and the bottom inner side of the mounting component 2 is provided with a threaded opening 21. The threaded opening 21 is threadedly connected to the threaded head 12, that is, the threaded head 12 is connected through the threaded opening 21, so that the mounting component 2 is installed on the mounting base 1, and vice versa. The rotation direction of the diamond drill bit is opposite to the thread direction of the threaded opening 21. A drill rod 3 is provided above the mounting component 2, and drill teeth 4 are provided above the drill rod 3. The drill rod 3 and drill teeth 4 are the main structure of the diamond drill bit, that is, used for drilling holes and wells.

[0024] The drill rod 3 has a connecting post 33 at its bottom and a connecting port 22 on the inner side of the mounting part 2. The connecting post 33 is installed and removed from the connecting port 22. The drill rod 3 is installed on the mounting part 2 by connecting the connecting post 33 to the connecting port 22. Limit rails 23 are provided on both sides of the inner wall of the connecting port 22, and limit strips 32 are provided on both sides of the connecting post 33. The limit strips 32 are slidably connected to the limit rails 23. The other two sides of the inner wall of the connecting port 22 have first fixing ports 24, and the other two sides of the connecting post 33 have first threaded ports 31. The limit rails 23 limit the limit strips 32, allowing the connecting post 33 to slide in the connecting port 22. The first threaded ports 31 mate with the first fixing ports 24. The first hexagon socket head cap screws 13 are provided on the outer side of the first fixing ports 24. The first hexagon socket head cap screws 13 are threadedly connected to the first threaded ports 31. The drill rod 3 is fixed by passing through the first fixing ports 24 and connecting to the first threaded ports 31. Conversely, it can be disassembled.

[0025] The drill bit 4 has an installation strip 41 at its bottom and an installation groove 42 on the outside of the drill rod 3. The installation strip 41 and the installation groove 42 are slidably connected. The installation strip 41 has a second fixing port 44 and the installation groove 42 has a second threaded port 43. The drill bit 4 is installed on the drill rod 3 by connecting the installation groove 42 to the installation strip 41. The second fixing port 44 is connected to the second threaded port 43. A second hexagon socket head cap screw 14 is provided on the outside of the second fixing port 44. The second hexagon socket head cap screw 14 is threadedly connected to the second threaded port 43. The drill bit 4 is fixedly installed on the drill rod 3 by passing through the second fixing port 44 and connecting to the second threaded port 43. Disassembly is performed by reversing the process. Therefore, when a drill bit 4 is damaged, only the damaged drill bit 4 needs to be removed, without disassembling and replacing the entire drill bit. This not only makes operation more convenient but also reduces the cost of the drill bit.

[0026] The working principle of this utility model is as follows: The entire diamond drill bit is installed through the external thread 11. The threaded head 12 is connected through the threaded port 21, thereby installing the mounting part 2 on the mounting base 1. Conversely, disassembly is performed. The connecting post 33 is connected to the connecting port 22, thereby installing the drill rod 3 on the mounting part 2. The limiting rail 23 limits the limiting strip 32, thereby allowing the connecting post 33 to slide in the connecting port 22. The first threaded port 31 is connected to the first fixing port 24. The first internal hex bolt 13 passes through the first fixing port 24 and connects to the first threaded port 31, thereby fixing the drill rod 3. Conversely, disassembly is performed. The mounting strip 41 is connected to the mounting groove 42, thereby installing the drill tooth 4 on the drill rod 3. The second fixing port 44 is connected to the second threaded port 43. The second internal hex bolt 14 passes through the second fixing port 44 and connects to the second threaded port 43, thereby fixing the drill tooth 4 on the drill rod 3. Conversely, disassembly is performed. Thus, when a drill tooth 4 is damaged, only the damaged drill tooth 4 needs to be removed, without disassembling and replacing the entire drill bit.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
