Description

Technical Field

[0001] This utility model relates to the field of geological exploration tools, specifically a multifunctional geological exploration drill bit. Background Technology

[0002] Geological exploration is a survey and research activity that involves exploring and detecting geology through various means and methods to determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. In mineral prospecting, it is used to discover industrially significant mineral deposits, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide mineral reserves and geological data required for mine construction design. However, existing drilling equipment can only take samples after drilling is completed. During drilling, the drill rod positioning is inaccurate, and after drilling is completed, the drill rod needs to be cleaned and maintained, and disassembly is relatively difficult.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221879307U) discloses a multifunctional geological exploration drill bit, including a drive shaft, a spiral conveyor blade fixedly connected to the outside of the drive shaft, a connecting flange fixedly connected to the top of the drive shaft, and a drilling fixing mechanism fixedly connected to the bottom of the outside of the drive shaft. The drilling fixing mechanism includes two first movable bases, each with a first movable ring movably connected to its outer side. Each of the two first movable rings has a telescopic rod fixedly connected to one side, and each of the two telescopic rods has a second movable ring fixedly connected to one end. Compared with existing technologies, this utility model, by setting up a drilling fixing mechanism, allows the angle of the two telescopic rods to be adjusted via the first movable bases and first movable rings. After the two telescopic rods extend, they drive the scraper to adjust its angle via the second movable rings and second movable bases. This can stabilize the soil on the inner wall of the borehole during drilling, reduce soil loss, and improve drilling efficiency.

[0004] Although the aforementioned patent, by setting up a fixed collar, transmission block, push block, arc-shaped block, rotating push rod, locking post, transmission groove, and limiting groove, improves the stability of the drill bit by setting up a fixed collar, transmission block, push block, arc-shaped block, rotating push rod, locking post, transmission groove, and limiting groove, compared with the prior art, two rotating push rods drive two push blocks to engage with the limiting groove on the outside of the locking post through the arc-shaped block on one side, and then the transmission block at the bottom of the fixed collar engages with the transmission groove at the top of the locking post, so that the transmission shaft drives the drill bit to rotate. However, the limiting by the external transmission push rod of the drill bit makes it easy for the rock to come into contact with the transmission push rod and wear during drilling. At the same time, the gap between the transmission push rod and the drill bit is easy to fill with mud and sand during drilling, making disassembly more difficult and resulting in poor stability.

[0005] Therefore, this utility model provides a multifunctional geological exploration drill bit to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a multifunctional geological exploration drill bit, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: It includes a rotating rod and a drill bit. A cylinder is fixedly connected to the bottom of the rotating rod, and a circular groove is formed inside the top of the drill bit. A convenient assembly includes multiple insert rods, all of which are slidably connected to the inside of the cylinder. Multiple insertion holes matching the insert rods are formed on the inner wall of the circular groove. A limit plate is fixedly connected to one end of each insert rod. A trigger block is slidably connected inside the cylinder, and a top rod is threadedly connected inside the rotating rod. During use, the convenient assembly allows for quick locking of the drill bit and rotating rod after they are engaged, improving stability and ensuring the external integrity of the drill bit and rotating rod. This prevents rocks and sand from damaging the convenient assembly during drilling operations. This design prevents wear and blockage, ensuring the stability of the convenient components and making the drill bit more efficient and quick to disassemble, replace, or maintain. It prevents blockages caused by long-term use from affecting disassembly efficiency. During installation, the cylinder engages with the inside of the groove, allowing the drill bit and rotating rod to lock together. Rotating the push rod causes it to move downwards along the internal threads of the rotating rod. The push rod then exerts a reverse force on the trigger block, causing it to slide downwards synchronously inside the cylinder. As the trigger block slides downwards, its external inclined section applies a reverse force to multiple limiting plates, ultimately causing multiple insert rods to extend outwards from the cylinder. Finally, the insert rods are locked inside the insertion holes, achieving a locking mechanism after the drill bit and rotating rod are engaged. During disassembly, reversing the push rod and simultaneously using the return spring force allows the insert rods to disengage from the insertion holes and be stored inside the cylinder, achieving quick disassembly.

[0008] As a preferred technical solution of this application, the inside of the rotating rod is provided with a threaded groove that meshes with the outside of the push rod, and a nut is fixedly connected to the top of the push rod. The nut can be easily matched and adjusted with tools to control the lifting and lowering of the push rod inside the rotating rod, so that the push rod slides down and squeezes the trigger block.

[0009] As a preferred technical solution of this application, a reset spring is sleeved on the outside of each of the plurality of insertion rods. The reset spring is made of stainless steel. The spring force of the reset spring acts in the opposite direction on the limiting plate, so that when the trigger block does not apply force to the limiting plate, the insertion rod will retract into the inside of the cylinder.

[0010] As a preferred technical solution of this application, a telescopic rod is fixedly connected to the bottom of the trigger block, and a limiting spring is sleeved on the outside of the telescopic rod. Through the limiting spring, when the top rod no longer applies force to the trigger block, the elastic force of the reset spring can make the trigger block slide upward inside the cylinder and no longer apply force to the limiting plate.

[0011] As a preferred technical solution of this application, the inner wall of the circular groove is uniformly provided with ribs, and the outside of the cylinder is uniformly fixedly connected with ribs that match the ribs. The ribs can be locked inside the ribs, so that the cylinder can be locked inside the circular groove.

[0012] As a preferred technical solution of this application, the trigger block has a conical structure, and the inside of the cylinder has a cavity for the trigger block to slide up and down. The outer conical oblique section of the trigger block can cause the trigger block to exert a reverse force on each limiting plate when it slides down, and push each plug rod to the outside of the cylinder.

[0013] As a preferred technical solution of this application, a spiral conveying plate is fixedly connected to the outside of the rotating rod, and a connecting flange is fixedly connected to the top of the rotating rod. During the drilling operation, the spiral conveying plate can transport the soil inside the hole to the outside of the hole, and the connecting flange can facilitate the matching and connection of the rotating rod with one end of the motor drive shaft.

[0014] (III) Beneficial Effects During use, the convenient component allows for quick locking of the drill bit and rotating rod after they are engaged, improving stability and ensuring the integrity of the drill bit and rotating rod. This prevents rock and sand from causing wear and blockage during drilling operations, ensuring the stability of the convenient component. It also makes the disassembly, replacement, and maintenance of the drill bit more efficient and faster, preventing blockages caused by long-term use from affecting disassembly efficiency.

[0017] 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.

[0018] This utility model provides a multifunctional geological exploration drill bit, such as Figure 1-4 As shown, the multi-functional geological exploration drill bit includes a rotating rod 2 and a drill bit 1. A cylinder 7 is fixedly connected to the bottom of the rotating rod 2, and a circular groove 6 is opened inside the top of the drill bit 1. The convenient assembly includes multiple insertion rods 10, all slidably connected inside the cylinder 7. Multiple insertion holes 8, matching the insertion rods 10, are provided on the inner wall of the circular groove 6. Limit plates 15 are fixedly connected to opposite ends of the insertion rods 10. A trigger block 12 is slidably connected inside the cylinder 7, and a top rod 5 is threadedly connected inside the rotating rod 2. During use, the convenient assembly allows for quick locking of the drill bit 1 and rotating rod 2 after they are engaged, improving stability and ensuring the external integrity of the drill bit 1 and rotating rod 2. This prevents rock and sand from causing wear and blockage to the convenient assembly during drilling operations, ensuring its stability and ease of disassembly, replacement, or maintenance of the drill bit 1. The process is more efficient and faster, and will not be affected by blockage due to long-term use, thus improving disassembly efficiency. During use and installation, the cylinder 7 is engaged inside the groove 6, which allows the drill bit 1 and the rotating rod 2 to be engaged. Then, the top rod 5 is rotated to make it move downward inside the rotating rod 2. Finally, the top rod 5 will exert a reverse force on the trigger block 12, causing the trigger block 12 to slide downward synchronously inside the cylinder 7. When the trigger block 12 slides downward, its external inclined section will exert a reverse force on multiple limiting plates 15, which will eventually cause multiple insertion rods 10 to extend outward from the cylinder 7. Finally, the insertion rods 10 are engaged inside the insertion hole 8, realizing the limiting lock after the drill bit 1 and the rotating rod 2 are engaged. During disassembly, by reversing the top rod 5 and simultaneously using the elastic force of the return spring 11, the insertion rods 10 can be disengaged from the insertion hole 8 and stored inside the cylinder 7, achieving the effect of quick disassembly.

[0019] The rotating rod 2 has a threaded groove inside that meshes with the outside of the push rod 5. The top of the push rod 5 is fixedly connected to a nut 16. The nut 16 can be easily matched and adjusted with tools to control the threaded lifting and lowering of the push rod 5 inside the rotating rod 2, so that the push rod 5 slides down and presses the trigger block 12. Each of the multiple insert rods 10 is fitted with a return spring 11. The return spring 11 is made of stainless steel. The elastic force of the return spring 11 acts in the opposite direction on the limiting plate 15, so that when the trigger block 12 does not apply force to the limiting plate 15, the insert rod 10 will retract into the inside of the cylinder 7.

[0020] A telescopic rod 13 is fixedly connected to the bottom of the trigger block 12. A limiting spring 14 is sleeved on the outside of the telescopic rod 13. Through the limiting spring 14, when the top rod 5 no longer applies force to the trigger block 12, the elastic force of the reset spring 11 allows the trigger block 12 to slide upward inside the cylinder 7 and no longer apply force to the limiting plate 15. The inner wall of the circular groove 6 is uniformly provided with ribs 9. Ribs that match the ribs 9 are uniformly fixedly connected to the outside of the cylinder 7. The ribs can be locked inside the ribs 9, so that the cylinder 7 can be locked inside the circular groove 6. The trigger block 12 has a conical structure. The inside of the cylinder 7 has a cavity for the trigger block 12 to slide up and down. The outer conical oblique section of the trigger block 12 allows it to exert a reverse force on each limiting plate 15 when it slides down, and push each insert rod 10 to the outside of the cylinder 7. The outside of the rotating rod 2 is fixedly connected to a spiral conveying plate 3, and the top of the rotating rod 2 is fixedly connected to a connecting flange 4. During the drilling operation, the spiral conveying plate 3 can transport the soil inside the hole to the outside of the hole. The connecting flange 4 can facilitate the matching and connection between the rotating rod 2 and one end of the motor drive shaft.

[0021] When using this multi-functional geological exploration drill bit, during installation, the cylinder 7 engages with the inside of the groove 6, allowing the drill bit 1 and the rotating rod 2 to be locked together. Then, rotating the push rod 5 causes it to move downwards along the thread inside the rotating rod 2. Ultimately, the push rod 5 exerts a reverse force on the trigger block 12, causing the trigger block 12 to slide downwards synchronously inside the cylinder 7. As the trigger block 12 slides downwards, its external inclined section exerts a reverse force on multiple limiting plates 15, ultimately causing multiple insertion rods 10 to extend outwards from the cylinder 7. Finally, the insertion rods 10 are locked inside the insertion hole 8, achieving the limiting and locking of the drill bit 1 and the rotating rod 2 after engagement. During disassembly, reversing the push rod 5 synchronously utilizes the elastic force of the return spring 11, allowing the insertion rods 10 to disengage from the insertion hole 8 and be stored inside the cylinder 7, achieving a quick disassembly effect.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
