[0003] The connection process between traditional rotary drilling bits and drilling rigs is relatively complex and inconvenient to disassemble and install, which further affects the working efficiency of the drill bit, making the time for single pile drilling exceed 15 days. At the same time, under long-term operation, traditional drill bits are prone to breakage and loosening of bolts and nuts at the connection points due to temperature rise and vibration, requiring secondary tightening, which reduces working efficiency.

[0004] The existing patent (publication number: CN222542363U) discloses a composite drill bit for rotary drilling rigs. This utility model can overcome the difficulties of conventional drill bits, such as slipping easily when encountering water in mudstone formations and slow drilling speed, thereby improving construction efficiency and reducing construction costs.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the drill bits of some existing geological drilling rigs are connected to the drill rod of the rig via threads, which is inconvenient for both connection and disassembly. Furthermore, due to the large end face area of ​​the drill bit, it is not convenient to accurately position the drill bit at the required drilling location, resulting in a relatively limited functionality.

[0006] Therefore, a multifunctional geological drilling rig composite drill bit is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A multifunctional geological drilling rig composite drill bit includes a drill bit body 1 and a drill rod body 2. The bottom of the drill bit body 1 is provided with a positioning mechanism 5. The front and rear sides of the bottom of the drill rod body 2 are fixedly connected with connecting blocks 10. The top of the drill bit body 1 is provided with a connecting mechanism 8. The inside of the drill rod body 2 is provided with a water supply pipe 3. The bottom of the drill bit is provided with drill teeth 9.

[0030] The positioning mechanism 5 includes a tapered drill 501, a rod 502, a screw 503, and a barrel 504. The bottom of the rod 502 is fixedly connected to the bottom of the tapered drill 501. The rod 502 is movably inserted into the inside of the barrel 504. The screw 503 passes through the barrel 504 on the side near the barrel 504 and is threadedly connected to the inside of the rod 502.

[0031] In this embodiment: the conical drill 501 is inserted into the ground with its sharp shape, and the tip guides the drill bit body 1 to find the correct position. After the rectangular insert rod 502 is initially fixed to the insert barrel 504, the screw 503 is tightened to ensure stability, providing support for the drill teeth 9 to drill. Regarding the connection between the drill rod body 2 and the drill bit body 1, the bottom connecting block 10 of the drill rod body 2 is inserted into the connecting frame 804 of the drill bit body 1. Pulling the pull ring 801 causes the connecting rod 803 to pass through the connecting block 10 and the connecting frame 804. The magnetic block 802 attracts the connecting frame 804 to achieve initial positioning. The limiting button 15 of the elastic clip 14 locks into the limiting hole 6 for further reinforcement, ensuring a stable connection and facilitating rapid drilling. During disassembly and operation, the water supply pipe 3 inside the drill rod body 2 is connected to an external water source. Water is sprayed out from the drain nozzle 13 through the fixed pipe 12 to cool the drill teeth 9 and wash away debris. The debris is discharged through the chip removal hole 7 by the external suction device, meeting the multi-functional requirements. At the same time, the drill bit body 1, drill teeth 9, etc. are made of composite high-strength materials to enhance wear resistance and impact resistance, enabling them to withstand high pressure and torque, ensuring stable operation for a long time. This solves the problem that some existing geological drilling rigs connect the drill bit to the drill rod of the drilling rig through threads, which is inconvenient for connection and disassembly. In addition, due to the large end face area of ​​the drill bit, it is not convenient to accurately position the drill bit at the required drilling position, resulting in a relatively simple function.

[0032] Specifically, such as Figure 2 As shown, the connecting mechanism 8 includes a pull ring 801, two magnetic blocks 802, a connecting rod 803, and two connecting frames 804. The left side of the pull ring 801 is fixedly connected to the right side of the connecting rod 803. The top of the magnetic block 802 is fixedly connected to the bottom of the connecting rod 803. The connecting block 10 is movably inserted into the inside of the connecting frame 804. The left side of the connecting rod 803 passes through the connecting frame 804 and the connecting block 10 and extends to the outside of the connecting frame 804. The left side of the magnetic block 802 is magnetically attracted to the surface of the connecting frame 804.

[0033] Specifically, such as Figure 2 and Figure 6 As shown, elastic clips 14 are fixedly connected to the front and rear sides of the connecting rod 803. Limiting buttons 15 are fixedly connected to the surface of the elastic clips 14. Limiting holes 6 are opened on the surface of the connecting frame 804. The limiting buttons 15 are movably engaged inside the limiting holes 6.

[0034] Specifically, such as Figure 2 and Figure 4As shown, chip removal holes 7 are provided inside both the drill bit body 1 and the drill rod body 2.

[0035] In this embodiment: by inserting the connecting block 10 into the connecting frame 804, the hand-held pull ring 801 moves the connecting rod 803 through the connecting frame 804 and the connecting block 10, and the magnetic block 802 is attracted to the surface of the connecting frame 804 to achieve initial positioning. At the same time, after the elastic clip 14 on the connecting rod 803 passes through the limiting hole 6, the limiting button 15 locks the limiting hole 6, further enhancing the stability of the connection between the drill rod body 2 and the drill bit body 1. The debris generated during drilling can be discharged through the corresponding chip removal holes 7 inside the drill bit body 1 and the drill rod body 2 by an external suction device.

[0036] Specifically, such as Figure 3 As shown, a bracket 4 is fixedly connected to the bottom of the drill bit body 1, the top of the drill teeth 9 is fixedly connected to the bottom of the bracket 4, and the top of the insertion barrel 504 is fixedly connected to the bottom of the bracket 4.

[0037] Specifically, such as Figure 3 As shown, there are several drill teeth 9, which are staggered at the bottom of the support 4.

[0038] In this embodiment: the bracket 4 can provide stable support for the drill teeth 9, making it convenient for the drill teeth 9 to be arranged in an alternating manner, which facilitates geological exploration drilling work.

[0039] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, a fixed pipe 12 is fixedly connected to the inner wall of the drill bit body 1. The bottom of the water supply pipe 3 is fixedly connected to the top of the fixed pipe 12. A drain nozzle 13 is fixedly connected to the bottom of the fixed pipe 12. There are several drain nozzles 13, which are evenly distributed at the bottom of the fixed pipe 12. A through hole 11 is opened inside the drill rod body 2. The top of the water supply pipe 3 passes through the through hole 11 and extends into the interior of the drill rod body 2.

[0040] Specifically, such as Figure 3 As shown, the drill bit body 1, drill teeth 9, support 4, and tapered drill 501 are all made of composite high-strength material.

[0041] In this embodiment: the water supply pipe 3 is connected to an external water source, and the water flows into the water supply pipe 3 through the through hole 11, is transported downward to the fixed pipe 12, and is then sprayed out through the evenly distributed drain nozzles 13 to cool the drill teeth 9 and wash away the debris generated during drilling. Since the drill bit body 1, drill teeth 9, bracket 4 and conical drill 501 are made of composite high-strength materials, they have stronger wear resistance and impact resistance, ensuring stable operation for a long time.

[0042] Working principle: In the positioning mechanism 5 at the bottom of the drill bit body 1, the tapered drill 501, with its sharp shape, can quickly insert into the ground at the point where drilling is required before drilling operations. Utilizing its tip guiding characteristics, it accurately locates the drilling position for the drill bit body 1, which has a large end face. The rectangular insert rod 502 and the insert can 504 are inserted together to initially fix the tapered drill 501. Then, the screw 503 is tightened through the threaded connection between the insert can 504 and the insert rod 502 to ensure the tapered drill 501 is stable and does not loosen, thus facilitating accurate drilling of the subsequent drill teeth 9. The drilling provides stable support. The drill rod body 2 and the drill bit body 1 are connected by a plug-in connection mechanism 8. The connecting block 10 at the bottom of the drill rod body 2 is inserted into the connecting frame 804 at the top of the drill bit body 1. The connecting rod 803 is moved through the connecting frame 804 and the connecting block 10 by holding the pull ring 801. The magnetic block 802 is attracted to the surface of the connecting frame 804 to achieve initial positioning. At the same time, after the elastic clip 14 on the connecting rod 803 passes through the limiting hole 6, the limiting button 15 locks the limiting hole 6, further enhancing the stability of the connection. To prevent the drill rod body 2 from detaching from the drill bit body 1 during operation, this method facilitates quick installation and disassembly. The water supply pipe 3 inside the drill rod body 2 is connected to an external water source. Water flows through the through hole 11 into the water supply pipe 3, is transported downward to the fixed pipe 12, and then sprayed out through the evenly distributed drain nozzles 13 to cool the drill teeth 9 and wash away the debris generated during drilling. The debris can be discharged through the chip removal holes 7 inside the drill bit body 1 and the drill rod body 2 by an external suction device, meeting the needs of multi-functional use. The drill bit body 1, drill teeth 9, bracket 4 and conical drill 501 are made of composite high-strength material, which makes them more wear-resistant and impact-resistant. They can maintain good performance when subjected to huge pressure and torque during drilling, ensuring stable operation for a long time. This solves the problem that the drill bit of some existing geological drilling rigs is connected to the drill rod of the drilling rig by threads, which is inconvenient for connection and disassembly. In addition, due to the large end face area of ​​the drill bit, it is not convenient to accurately position the drill bit at the required drilling position, resulting in a relatively single function.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
