Technical Field
[0001] The utility model relates to the technical field of drill bits for civil engineering, in particular to a wear-resistant drill bit for pile foundations. Background Art
[0002] Wear-resistant drill bits for pile foundations generally refer to tools used to drill holes in the ground or rock in order to install pile foundations. These drill bits need to have good wear resistance because they need to withstand the friction and wear of geological materials during continuous rotation and entry into the ground. This type of drill bit is usually made of high-strength alloy material and undergoes special heat treatment and surface coating treatment to enhance its hardness and wear resistance. In addition, the geometry and structure of the drill bit also need to be considered during design to improve its drilling efficiency and durability under various geological conditions.
[0003] The existing patent (publication number: CN220267597U) proposes a pile foundation drill bit. The utility model includes an adjustable adjusting arm, the width of which can be adjusted as needed, so it can flexibly respond to the excavation needs of pile foundations of different diameters, greatly improving the excavation efficiency; by designing a cylinder and a linkage arm, the width of the adjusting arm can be changed, making the excavation process more refined and improving the excavation accuracy; the serrations at the bottom of the excavation plate and the grinding head on the outside of the adjusting arm make the excavation of the side walls and bottom of the pile foundation more in-depth and comprehensive.
[0004] However, existing high-efficiency pile foundation drill bits are often accompanied by high equipment costs and require good maintenance to maintain their performance, which increases project budgets and operating costs. The drill bits are not easy to disassemble. When encountering obstacles or needing to replace the drill bits to adapt to different strata, the operation becomes complicated and time-consuming. When worn parts need to be replaced or repairs are required, the drill bits cannot be quickly disassembled, which slows down the progress of the project. Therefore, the utility model proposes a wear-resistant drill bit for pile foundations to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the shortcomings in the prior art and provides a wear-resistant drill bit for pile foundation.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wear-resistant drill bit for pile foundation, comprising a drill rod, a threaded blade is fixed on the drill rod, a drill bit is arranged at the bottom of the drill rod, a drill blade is arranged on the drill bit, and a disassembly assembly is arranged on the drill rod;
[0007] The disassembly assembly includes a fixed column, a slot is provided on the fixed column, a fixed seat is provided on the drill rod, a limiting slot is provided on the fixed seat, a rotating shaft is rotatably connected to the side of the fixed seat close to the limiting slot, a clamping block is fixed on the rotating shaft, and a handle is fixed on the clamping block.
[0008] As a preferred embodiment of a wear-resistant drill bit for pile foundation, the drill blade is configured as an inclined surface.
[0009] The beneficial effects of adopting the above further scheme are: the drill blade with an inclined surface can help the drill bit to be more easily positioned when starting to drill the pile foundation, reduce deviation, and thus improve the position accuracy of the pile foundation; the drill blade with an inclined surface can make the drill bit enter the ground more gradually, thereby reducing initial resistance, which helps prevent the drill bit from bending or breaking; the inclined drill blade helps to better guide soil blocks to be discharged from the inclined surface, avoid chip blockage, and improve the efficiency and quality of pile foundation drilling.
[0010] As a preferred embodiment of a wear-resistant drill bit for pile foundation, the material of the drill bit is diamond.
[0011] The beneficial effects of adopting the above further scheme are: diamond is the hardest material known in nature, so it can easily drill through various hard materials such as stone, concrete, ceramics and some metals. Due to its high hardness, diamond drill bits wear more slowly during use, which means that they can last longer without replacement, reducing long-term use costs.
[0012] As a preferred embodiment of a wear-resistant drill bit for a pile foundation, the fixing column is fixed on a drill rod, and the fixing seat sleeve is arranged on the drill rod.
[0013] The beneficial effect of adopting the above further solution is that since the fixing column is fixed on the drill rod, the drill rod supports and fixes the fixing column, and since the fixing seat is sleeved on the drill rod, the fixing seat can be connected to the drill rod.
[0014] As a preferred embodiment of a wear-resistant drill bit for a pile foundation, the fixing column is slidably connected in the limiting groove.
[0015] The beneficial effect of adopting the above further solution is that since the fixing column is slidably connected to the limiting groove, the limiting groove can limit the fixing column.
[0016] As a preferred embodiment of a wear-resistant drill bit for pile foundation, the clamping block is clamped in the clamping groove.
[0017] The beneficial effect of adopting the above further solution is that since the clamping block is clamped in the clamping slot, the clamping block can fix the fixing column in the clamping slot, thereby fixing the drill rod on the fixing seat.
[0018] Compared with the prior art, the advantages and positive effects of the utility model are:
[0019] The operator slides the fixed column fixed on the drill rod into the limit groove provided on the fixed seat. When the fixed column moves to the side close to the clamping block, the handle is turned, and the handle drives the clamping block to rotate on the rotating shaft, and the clamping block is clamped in the clamping groove provided on the fixed column, so that the drill rod can be fixed on the fixed seat. The threaded blade is set so that the threaded blade can bring the broken soil out of the pile foundation. Since the drill blade is set as an inclined surface, the drill blade has a certain angle with the ground, thereby solving the technical problem of the overall easy disassembly and installation of the drill bit.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a wear-resistant drill bit for pile foundation, comprising a drill rod 1, a threaded blade 2 is fixed on the drill rod 1, a drill bit 3 is arranged at the bottom of the drill rod 1, a drill blade 4 is arranged on the drill bit 3, and a disassembly component 5 is arranged on the drill rod 1;
[0029] like Figure 1 - Figure 3As shown, the disassembly assembly 5 includes a fixing column 51, a slot 52 is provided on the fixing column 51, a fixing seat 53 is provided on the drill rod 1, a limiting slot 54 is provided on the fixing seat 53, a rotating shaft 55 is rotatably connected to the side of the fixing seat 53 close to the limiting slot 54, a clamping block 56 is fixed on the rotating shaft 55, and a handle 57 is fixed on the clamping block 56. The operator first aligns the fixing column 51 on the drill rod 1 with the limiting slot 54 on the fixing seat 53 and slides the fixing column 51 to connect them. When the fixing column 51 moves to a position close to the clamping block 56, the operator rotates the handle 57, and the clamping block 56 is rotated on the fixing shaft 55 and clamped into the slot 52 of the fixing column 51 through mechanical transmission, so that the drill rod 1 is firmly locked on the fixing seat 53. This design simplifies the installation and disassembly process of the drill rod 1 and improves the work efficiency. In addition, the design of the threaded blade 2 makes During the drilling process, the broken soil can be effectively brought out from the pile foundation, thus avoiding the accumulation of broken soil at the bottom of the hole, reducing the blockage problem during drilling, and improving the drilling efficiency. At the same time, since the drill blade 4 is set as an inclined surface and forms a certain angle with the ground, this helps the drill blade 4 to cut into the ground more easily, reduces the wear of the drill bit 3, and increases the drilling speed. The inclined design of the drill blade 4 is also beneficial to improving the guiding performance of the drill bit 3, making the drill hole more straight and improving the drilling accuracy. This design is particularly suitable for deep hole drilling operations under complex geological conditions, and can effectively cope with the drilling needs of different strata such as hard soil layers and gravel layers. Since the material of the drill bit 3 is diamond, diamond is the hardest material known in nature, so it can easily drill through various hard materials, thereby solving the technical problem of the overall easy disassembly and installation of the drill bit 3.
[0030] The above scheme still has the problem that the drill bit 3 cannot improve the pile foundation drilling accuracy when drilling the pile foundation, and cannot meet the deep hole drilling operation under complex geological conditions, such as Figure 1 as well as Figure 3 - Figure 4 As shown: the drill blade 4 is set as an inclined surface. The drill blade 4 with an inclined surface can help the drill bit 3 to be positioned more easily when starting to drill the pile foundation, reduce deviation, and thus improve the position accuracy of the pile foundation. The drill blade 4 with an inclined surface can make the drill bit 3 more gradual when entering the ground, thereby reducing initial resistance, which helps to prevent the drill bit 3 from bending or breaking. The inclined drill blade 4 helps to better guide the discharge of soil blocks from the inclined surface, avoid chip blockage, and improve the efficiency and quality of pile foundation drilling. The material of the drill bit 3 is diamond, which is the hardest material currently known in nature, so it can easily drill through various hard materials, such as stone, concrete, ceramics and some metals. Due to its high hardness, the diamond drill bit 3 wears slowly during use, which means that they can last longer without replacement, reducing long-term use costs;
[0031] like Figure 1 - Figure 3As shown, the fixing column 51 is fixed on the drill rod 1, and the fixing seat 53 is sleeved on the drill rod 1. Since the fixing column 51 is fixed on the drill rod 1, the drill rod 1 supports and fixes the fixing column 51. Since the fixing seat 53 is sleeved on the drill rod 1, the fixing seat 53 can be connected to the drill rod 1. The fixing column 51 is slidably connected in the limiting groove 54. Since the fixing column 51 is slidably connected in the limiting groove 54, the limiting groove 54 can limit the fixing column 51. The clamping block 56 is clamped in the clamping groove 52. Since the clamping block 56 is clamped in the clamping groove 52, the clamping block 56 can fix the fixing column 51 in the clamping groove 52, thereby fixing the drill rod 1 on the fixing seat 53.
[0032] Working principle:
[0033] like Figure 1-4 As shown in the figure, the operator first aligns the fixing column 51 on the drill rod 1 with the limiting groove 54 on the fixing seat 53 and slides them together. When the fixing column 51 moves to a position close to the clamping block 56, the operator turns the handle 57, and through mechanical transmission, the clamping block 56 rotates on the rotating shaft 55 and clamps into the clamping groove 52 of the fixing column 51, thereby firmly locking the drill rod 1 on the fixing seat 53. This design simplifies the installation and removal process of the drill rod 1 and improves work efficiency. In addition, the design of the threaded blade 2 enables the crushed soil to be effectively taken out of the pile foundation during the drilling process, avoiding the accumulation of crushed soil at the bottom of the hole and reducing the blockage problem during drilling. At the same time, since the drill blade 4 is set as an inclined surface and forms a certain angle with the ground, it is helpful for the drill blade 4 to cut into the ground more easily, reducing the wear of the drill bit 3 and increasing the drilling speed. The inclined design of the drill blade 4 is also conducive to improving the guiding performance of the drill bit 3, making the drill hole more straight and improving the drilling accuracy. This design is particularly suitable for deep hole drilling operations under complex geological conditions and can effectively cope with the drilling needs of different strata such as hard soil layers and gravel layers. Since the material of the drill bit 3 is diamond, which is the hardest material known in nature, it can easily drill through various hard materials.
