Technical Field
[0001] This invention belongs to the field of drill bit technology, and particularly relates to a noise-reducing drill bit and its usage method. Background Technology
[0002] In the drilling process, the drill bit is the main tool for breaking rocks, and the wellbore is formed by the drill bit breaking rocks. The quality of a wellbore formation and the time it takes to form depend not only on the characteristics of the rock formation being drilled and the performance of the drill bit itself, but also on the degree of compatibility between the drill bit and the formation. The proper selection of the drill bit plays an important role in improving drilling speed and reducing overall drilling costs.
[0003] When using drill bits normally, in order to meet market demands, optimization is generally focused on how to drill holes better and how to make them more convenient for users. However, noise reduction is often overlooked. Drill bits do have the advantages of better drilling results and easier user use, but they have certain limitations. During normal use, drill bits tend to throw soil from side to side and are very noisy.

The two positioning grooves are respectively opened on the left and right sides of the bottom of the push plate. The outer surfaces of the two moving blocks are slidably connected to the inside of the positioning grooves. The two ends of the two support rods are movably connected to the first annular block and the moving blocks, respectively.
[0008] The auxiliary components include annular support inclined block, support inclined rod and support top block. The two ends of the annular support inclined block are fixedly connected to the inner wall of the drill body. The support inclined rod is fixedly installed on the top of the inner wall of the drill body. The other end of the support inclined rod is fixedly connected to the annular support inclined block. The support top block is fixedly installed on one side of the support inclined rod. The end of the support top block away from the support inclined rod is fixedly connected to the annular support inclined block.
[0009] In a preferred embodiment of the present invention, the positioning element includes a threaded through hole, which is located on the rear side of the first annular block. The front side of the threaded through hole communicates with the interior of the first annular block. A threaded rod is threadedly connected to the interior of the threaded through hole. The front side of the threaded rod passes through the threaded through hole and is flush with the inner wall of the first annular block. The front side of the threaded rod is used in conjunction with the outer surface of the push rod. The rear side of the threaded rod passes through the threaded through hole and extends to the rear side of the first annular block. A rotating handle is fixedly installed on the rear side of the threaded rod.
[0010] As a preferred embodiment of the present invention, the top of the auxiliary drill bit is provided with a tapered groove, and the number of tapered grooves is multiple and evenly distributed.
[0011] As a preferred embodiment of the present invention, a vibrating block is fixedly installed on the top of the push plate, the top of the vibrating block is conical, and a vibrator is used in conjunction with the bottom of the vibrating block, the vibrator being embedded in the top of the push plate.
[0012] Preferably, a protective block is embedded in the top of the push plate, and the height of the protective block is higher than the height of the vibrator. The top of the protective block cooperates with the bottom of the vibrating block.
[0013] As a preferred embodiment of the present invention, the push rod is provided with strip grooves on both the left and right sides, and strip blocks are fixedly installed on both the left and right sides of the inner wall of the first annular block, with the opposite ends of the two strip blocks being slidably connected to the inside of the strip groove.
[0014] As a preferred embodiment of the present invention, the top of the auxiliary drill bit is provided with an annular groove, and a second annular block is used in conjunction with the inside of the annular groove. The outer surface of the second annular block is provided with uniformly distributed circular grooves.
[0015] A method of using a noise-reducing drill bit, wherein the noise-reducing drill bit is any one of the noise-reducing drill bits described in any one of the claims, the method of using the drill bit includes the following steps:
[0016] S1: First, connect the drill bit to the equipment to be used;
[0017] S2: Then, start working using the drill bit;
[0018] S3: Use a drill bit to drill a hole, and use an auxiliary drill bit to assist in drilling.
[0019] S4: During drilling, the waste generated during drilling enters the interior of the drill body through a circular through-hole;
[0020] S5: When waste enters the interior of the drill body, it squeezes the push plate, thereby causing the push rod to shorten, thus making better use of the drill body to collect waste;
[0021] S6: After the drill bit is removed, the push rod is pushed by the equipment, which then pushes the push plate to move inside the drill body, thereby achieving cleaning.
[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0023] 1. This invention uses a drill bit to drill holes and an auxiliary drill bit for further drilling, thus achieving better drilling results. During normal drilling, the soil is quickly thrown out by the rotating drill bit, which can easily cause blockages in the drill hole and generate a lot of noise. Therefore, a cavity is provided inside the drill body to store the soil. After the drill bit is removed from the soil, the device pushes the push rod to move, which effectively moves the push plate inside the drill body. At the same time, the use of the support rod, positioning groove, and moving block provides auxiliary pushing during the pushing process, resulting in better pushing effect and better noise reduction.
[0024] 2. The present invention uses manual rotation of the rotary handle to generate power for the entire positioning component. Since force can be transmitted, rotating the rotary handle simultaneously drives the threaded rod to rotate inside the threaded through hole, thus enabling the threaded rod to position the push rod and improving the positioning effect of the first annular block.
[0025] 3. By setting multiple conical grooves evenly distributed, the present invention can achieve good auxiliary storage and at the same time achieve good noise reduction.
[0026] 4. By setting up a vibrating block and a vibrator, the vibrating block can be driven to vibrate by the vibrator, which can loosen the soil squeezed inside the drill body, making the cleaning effect better and reducing noise.
[0027] 5. By setting a protective block that is higher than the height of the vibrator, the present invention can protect the vibrator, improve the vibration effect, and also improve the cleaning effect.
[0028] 6. By setting strip grooves and strip blocks, the present invention enables the first annular block to have an adjustable range, thereby improving the positioning effect.
[0029] 7. By setting an annular groove and a second annular block, and opening a uniformly distributed circular groove on the outer surface of the second annular block, the present invention not only prevents the use of the annular block for auxiliary drilling, but also enables the use of the circular groove for noise reduction.

[0037] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0038] The structure of the present invention will now be described in detail with reference to the accompanying drawings.
[0039] like Figures 1 to 6 As shown, an embodiment of the present invention provides a noise reduction drill bit, including a drill body 1 and a drill bit 2 for drilling. An auxiliary drill bit 3 for assisting drilling is provided between the drill body 1 and the drill bit 2. A cleaning component 4 for cleaning and an auxiliary ejection component 5 are provided inside the drill body 1. A circular through hole 7 for feeding is opened inside the drill bit 2. One end of the circular through hole 7 is connected to the inside of the drill body 1.
[0040] The cleaning component 4 includes a push rod 41, a push plate 42, a first annular block 43, two support rods 44, two positioning grooves 45, two moving blocks 46, and a positioning element 47. The outer surface of the push plate 42 is slidably connected to the inside of the drill body 1. The bottom of the push rod 41 is fixedly connected to the top of the push rod 41. The first annular block 43 is sleeved on the outer surface of the push rod 41. The positioning element 47 is located on the rear side of the first annular block 43. The two positioning grooves 45 are respectively opened on the left and right sides of the bottom of the push plate 42. The outer surfaces of the two moving blocks 46 are slidably connected to the inside of the positioning grooves 45. The two ends of the two support rods 44 are movably connected to the first annular block 43 and the moving blocks 46, respectively.
[0041] The auxiliary component 5 includes an annular support inclined block 51, a support inclined rod 52, and a support top block 53. The two ends of the annular support inclined block 51 are fixedly connected to the inner wall of the drill body 1. The support inclined rod 52 is fixedly installed on the top of the inner wall of the drill body 1. The other end of the support inclined rod 52 is fixedly connected to the annular support inclined block 51. The support top block 53 is fixedly installed on one side of the support inclined rod 52. The end of the support top block 53 away from the support inclined rod 52 is fixedly connected to the annular support inclined block 51.
[0042] refer to Figure 4 The positioning component 47 includes a threaded through hole 471, which is located on the rear side of the first annular block 43. The front side of the threaded through hole 471 is connected to the interior of the first annular block 43. A threaded rod 472 is threadedly connected to the interior of the threaded through hole 471. The front side of the threaded rod 472 passes through the threaded through hole 471 and is flush with the inner wall of the first annular block 43. The front side of the threaded rod 472 is used in conjunction with the outer surface of the push rod 41. The rear side of the threaded rod 472 passes through the threaded through hole 471 and extends to the rear side of the first annular block 43. A rotating handle 473 is fixedly installed on the rear side of the threaded rod 472.
[0043] The above solution is adopted: the power source of the entire positioning component 47 is realized by manually rotating the rotating handle 473. Since the force can be transmitted, while rotating the rotating handle 473, the threaded rod 472 is driven to rotate inside the threaded through hole 471. In this way, the threaded rod 472 can be positioned for the push rod 41, so that the positioning effect of the first annular block 43 is better.
[0044] refer to Figure 1 , Figure 2 and Figure 3 The top of the auxiliary drill bit 3 is provided with a tapered groove 6, and there are multiple tapered grooves 6, which are evenly distributed.
[0045] The above solution involves setting multiple conical grooves 6 evenly distributed to provide excellent auxiliary storage and also to effectively reduce noise.
[0046] refer to Figure 3 A vibrating block 8 is fixedly installed on the top of the push plate 42. The top of the vibrating block 8 is conical, and a vibrator 9 is used in conjunction with the bottom of the vibrating block 8. The vibrator 9 is embedded in the top of the push plate 42.
[0047] The above solution involves setting up a vibrating block 8 and a vibrator 9. The vibrator 9 can drive the vibrating block 8 to vibrate, thereby loosening the soil squeezed inside the drill body 1, improving the cleaning effect, and also reducing noise.
[0048] refer to Figure 3 A protective block 10 is embedded in the top of the push plate 42, and the height of the protective block 10 is higher than the height of the vibrator 9. The top of the protective block 10 is used in conjunction with the bottom of the vibrator 8.
[0049] The above solution involves setting up a protective block 10, which is higher than the height of the vibrator 9. This protects the vibrator 9, improves the vibration effect, and enhances the cleaning effect.
[0050] refer to Figure 3 The push rod 41 has strip grooves 11 on both the left and right sides. The inner wall of the first annular block 43 has strip blocks 12 fixedly installed on both the left and right sides. The two strip blocks 12 are slidably connected to the inside of the strip grooves 11 at opposite ends.
[0051] By adopting the above solution, by setting the strip groove 11 and the strip block 12, the first annular block 43 can have an adjustable range, thereby improving the positioning effect.
[0052] refer to Figure 2 The top of the auxiliary drill bit 3 is provided with an annular groove 13, and a second annular block 14 is used inside the annular groove 13. The outer surface of the second annular block 14 is provided with evenly distributed circular grooves 15.
[0053] The above solution is adopted: by setting an annular groove 13 and a second annular block 14, and opening a uniformly distributed circular groove 15 on the outer surface of the second annular block 14, not only can the second annular block 14 not be used for auxiliary drilling, but the circular groove 15 can also be used for noise reduction.
[0054] A method for using a noise-reducing drill bit, wherein the noise-reducing drill bit is any one of items 1-7, and the method of use includes the following steps:
[0055] S1: First, connect drill bit 2 to the equipment to be used;
[0056] S2: Then, start working using drill bit 2;
[0057] S3: Use drill bit 2 to drill a hole, while simultaneously using auxiliary drill bit 3 to assist in drilling;
[0058] S4: During drilling, the waste generated during drilling enters the interior of the drill body 1 through the circular through hole 7;
[0059] S5: When the waste enters the interior of the drill body 1, it squeezes the push plate 42, thereby causing the push rod 41 to shorten, so as to better utilize the drill body 1 to collect the waste.
[0060] S6: After the drill bit is removed, the push rod 41 is pushed by the equipment, and then the push plate 42 is pushed to move inside the drill body 1, thereby achieving cleaning.
[0061] Working principle of the invention:
[0062] In operation, drilling is first performed using drill bit 2, followed by auxiliary drilling bit 3 for further drilling. This ensures efficient drilling. During normal drilling, the soil is quickly ejected during rotation, which can easily cause blockages and generate significant noise. Therefore, a cavity is provided inside the drill body 1 to store the soil. After the drill bit is removed from the soil, the device pushes the push rod 41, which in turn moves the push plate 42 within the drill body 1. The push plate 42 is powered by manually rotating the rotary handle 473, which, being transmissible, simultaneously drives the threaded rod. The rod 472 rotates inside the threaded through hole 471, which enables the threaded rod 472 to be positioned relative to the push rod 41, thus improving the positioning effect of the first annular block 43. Then, the moving block 46 moves to its limit position inside the positioning groove 45, which improves the pushing effect and makes the force on the push plate 42 more even. Furthermore, the annular support inclined block 51 ensures that there will be no difficulty in pushing out due to the small outlet. At the same time, the support inclined rod 52 and the support top block 53 support the annular support inclined block 51 to prevent deformation of the annular support inclined block 51, which improves the pushing effect and also improves the noise reduction effect.
