Description

Technical Field

[0001] This utility model relates to the field of drill bit technology, and in particular to a drill bit that is easy to recycle. Background Technology

[0002] Excavation and drilling operations in soil, soft rock, and some loose strata require excavation equipment. This equipment uses drill bits to drill holes in the ground. Drill bits are common underground excavation tools, equipped with cutting blades and a cutting body, capable of quickly cutting and removing geological materials.

[0003] Publication No. CN2769486Y discloses a spiral drill bit, including a square connector, ribs, spiral blades, a central tube, and a front connector. It also includes a connecting disc mechanism and a reinforcing mechanism. The connecting disc mechanism is located between the central tube and the square connector. One side of the reinforcing mechanism is connected to the connecting disc and the square connector, and the other side is connected to the spiral blades. Using this structure, during mass production of spiral drill bits, it is no longer necessary to directly weld the square connector to the central tube, significantly reducing the number of spiral drill bits in stock. When needed, only the connecting disc mechanism needs to be welded to the drill rod connector compatible with a specific drilling rig, greatly shortening the delivery time. Although... The added reinforcing mechanism not only solved the problem of weld breakage and deformation between the spiral blade and the central tube, but also directly transmitted most of the drill bit's torque to the spiral blade and cutting tool through the four-way connector, reducing the stress on the central tube and solving the problem of central tube breakage. However, when recycling the cutter head and the cutter shank, they need to be recycled separately because the cutter head and the shank are made of different materials. Traditional drill bits are fixed to the cutter head and the shank by welding. When recycling, the cutter head and the shank need to be separated by heating or other methods. The whole process is cumbersome and dangerous, making it inconvenient for workers to recycle the drill bits. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drill bit that is easy to recycle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drill bit that is easy to recycle, comprising a mounting frame, a handle, a drill bit, and a spiral drill blade. The mounting frame is fixedly mounted on the top of the handle, the drill bit is disposed at the bottom of the handle, a hollow fixing rod is sleeved on the surface of the handle, the spiral drill blade is fixedly mounted on the surface of the hollow fixing rod, a slider is fixedly mounted on the surface of the handle, an annular connecting block is fixedly mounted at the bottom of the mounting frame near the handle, fixing holes A are provided at the top of the annular connecting block and the surface of the handle, a bolt is passed through the top of the surface of the hollow fixing rod, a mounting block is fixedly mounted on the top of the drill bit, a limit hole is provided at the bottom of the handle, a metal pin is passed through the bottom of the surface of the handle, and a fixing hole B is provided on the side of the mounting block.

[0006] Furthermore, a groove is formed inside the hollow fixing rod near the slider, and the groove is slidably connected to the slider. This allows the hollow fixing rod to move on the tool holder.

[0007] Furthermore, the bolt is slidably connected to the fixing hole A, and the bolt is also slidably connected to the hollow fixing rod. Therefore, the hollow fixing rod can be fixed to the tool holder by the bolt after it has been moved onto the tool holder.

[0008] Furthermore, the hollow fixing rod is slidably connected to the annular connecting block. This facilitates the disassembly of the hollow fixing rod.

[0009] Furthermore, the metal pin is slidably connected to the fixing hole B, and the limiting hole is slidably connected to the mounting block. This is to facilitate the disassembly of the cutter head.

[0010] Furthermore, both the bottom end of the cutter head and the bottom end of the auger blade are equipped with a crushing mechanism. The crushing mechanism includes a fixing block, which is fixedly installed at the bottom end of both the cutter head and the auger blade. A threaded rod is threaded through the interior of each fixing block, and a connecting piece is fixedly installed at the bottom end of the threaded rod. A diamond block is fixedly installed at the bottom end of the connecting piece. This allows the drill bit to adapt to different environments for drilling and excavation.

[0011] Furthermore, the threaded rod is threadedly connected to the fixing block. This is to facilitate the installation of the connecting parts.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a slider, bolt and hollow fixing rod, the spiral drill bit can be disassembled by moving on the tool holder, and then the tool head can be disassembled by moving the mounting block in the limiting hole. This avoids the phenomenon of separating the welded parts of the tool holder and tool head by heating or other processes, making the drill bit more convenient to retrieve.

[0014] 2. In this utility model, by setting up diamond, connector and fixing block, the drill bit can easily break the rock when drilling and excavating hard rocks during use, avoiding the phenomenon of damage to the auger or drill bit due to the hardness of the rock, making the drill bit more practical and able to drill and excavate in different environments.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a technical solution: a drill bit that is easy to recycle, including a mounting frame 1, a handle 2, a cutter head 11, and a spiral drill blade 6. The mounting frame 1 is fixedly installed on the top of the handle 2, the cutter head 11 is located at the bottom of the handle 2, a hollow fixing rod 4 is sleeved on the surface of the handle 2, and a groove 10 is formed inside the hollow fixing rod 4 near the slider 8. The groove 10 is slidably connected to the slider 8. The spiral drill blade 6 is fixedly installed on the surface of the hollow fixing rod 4, and the slider 8 is fixedly installed on the surface of the handle 2. An annular connecting block is fixedly installed at the bottom of the mounting frame 1 near the handle 2. Fixing holes A7 are formed on the surface of the annular connecting block and at the top of the surface of the handle 2. Bolts 5 are slidably connected to fixing holes A7 and to the hollow fixing rod 4. A bolt 5 is inserted through the top of the surface of the hollow fixed rod 4. An installation block 12 is fixedly installed on the top of the cutter head 11. A limit hole 13 is opened at the bottom of the cutter handle 2. A metal pin 14 is inserted through the bottom of the surface of the cutter handle 2. A fixing hole B15 is opened on the side of the installation block 12. The hollow fixed rod 4 is slidably connected to the annular connecting block. The metal pin 14 is slidably connected to the fixing hole B15. The limit hole 13 is slidably connected to the installation block 12. The design of the slider 8, bolt 5 and hollow fixed rod 4 is to allow the spiral drill bit 6 to be disassembled by moving on the cutter handle 2. Then, the cutter head 11 can be disassembled by moving the installation block 12 in the limit hole 13. This avoids the phenomenon of separating the welded parts of the cutter head 11 from the cutter handle 2 by heating or other processes, making the drill bit more convenient to retrieve.

[0025] Example 2

[0026] Please see Figure 3-4 Both the bottom end of the cutter head 11 and the bottom end of the spiral drill blade 6 are equipped with a crushing mechanism. The crushing mechanism includes a fixing block 9, which is fixedly installed at the bottom ends of the cutter head 11 and the spiral drill blade 6. A threaded rod 16 is provided through the inside of the fixing block 9. A connector 17 is fixedly installed at the bottom end of the threaded rod 16, and a diamond block 18 is fixedly installed at the bottom end of the connector 17. The threaded rod 16 and the fixing block 9 are threadedly connected. The design of the diamond block, connector 17 and fixing block 9 is to enable the drill bit to easily crush rocks when drilling and excavating harder rocks during use, avoiding damage to the spiral drill blade 6 or the drill bit due to the hardness of the rocks, making the drill bit more practical and capable of drilling and excavating in different environments.

[0027] Working principle: When the drill bit needs to be recycled, first pick up the metal rod and align it with one end of the metal pin 14. Use a hammer to strike the metal rod so that it presses against the metal pin 14 until the metal pin 14 moves out of the handle 2. Then move the drill bit 11 downwards and rotate the connector 17. The rotation of the connector 17 drives the threaded rod 16 to rotate until the threaded rod 16 rotates away from the fixing block 9, allowing the diamond on the connector 17 to be removed. At this time, use a wrench to rotate and move the bolt 5 until the bolt 5 moves away from the annular connecting block. Then move the hollow fixing rod 4 downwards. The movement of the hollow fixing rod 4 drives the slider 8 to move in the groove 10 until the hollow fixing rod 4 moves away from the handle 2, allowing the spiral drill bit 6 to be disassembled. Then, the spiral drill bit 6, handle 2, and drill bit 11 can be recycled separately.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
