Description

Technical Field

[0001] The utility model relates to the technical field of anti-sticking drill bits, and specifically relates to an internal and external flipping anti-sticking drill bit. Background Technique

[0002] A drill bit is a common drilling tool in the drilling and related industries. Drill bits are mainly classified into drag bits, roller cone bits, diamond bits and PDC bits according to types. Drag bits break rocks by cutting. Roller cone bits rely on the periodic longitudinal vibration generated by the overall rotation around the drill bit axis and the self-rotation of the roller cones to continuously compress and stretch the drill string. The lower drill string converts this periodically changing elastic deformation into an impact force on the formation through the teeth to break rocks. Diamond bits use diamond particles embedded in the bit matrix to break different types of rocks by plowing, crushing or grinding. PDC bits use self-sharpening PDC cutting teeth to cut into the formation and break rocks by cutting.

[0003] The existing technology has the following problems:

[0004] 1. In the traditional drill bit structure, the drill bit is prone to sand settling and sticking during drilling operations, resulting in the inability to guarantee the drilling efficiency of the device.

[0005] 2. In the traditional drill bit structure, the drill bit continuously rotates with the ground surface during drilling operations, resulting in serious vibration wear on the structure at the drill bit, and the service life of the drill bit cannot be guaranteed. Content of the Utility Model

[0006] In view of the deficiencies of the existing technology, the utility model provides an internal and external flipping anti-sticking drill bit, which solves the problems put forward in the background technique.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0009] Preferably, the buffer assembly includes a buffer plate, a damping rod, a connecting spring and a connecting cylinder. A connecting cylinder is fixedly connected to the top end inside the connecting seat. A buffer plate is slidably connected to the inner wall of the connecting cylinder.

[0013] Preferably, the number of the connecting springs is four groups. The positions of the connecting springs are co-centered. The connecting springs are evenly distributed at an equal angle on one side of the damping rod.

[0014] Preferably, a connecting groove adapted to the size of the buffer plate is formed on the inner wall of the connecting cylinder. The buffer plate is slidably connected to the inner wall of the connecting cylinder through the connecting groove.

[0015] Compared with the prior art, the present utility model provides an inside-out anti-sticking drill bit, which has the following beneficial effects:

[0016] 1. For the inside-out anti-sticking drill bit, the hydraulic rod is used to push the lifting platform to lift and lower. The lifting and lowering of the lifting platform drives the activity plate and the second connecting block to slide inside the clamping seat. The movement of the second connecting block drives the rotating rod to rotate along the position of the second connecting block. At the same time, the rotation of the rotating rod is used to push the first connecting block and the fixed seat to move. The movement of the fixed seat drives the connecting drill bit to rotate along the position of the fixed seat, so that the drill bit can be flipped to eliminate the effect of sand sticking during drilling. At the same time, the gap between the cutting teeth on the surface of the connecting drill bit can further improve the efficiency of the device for eliminating sediment.

[0017] 2. For the inside-out anti-sticking drill bit, when the connecting drill bit contacts the ground for drilling operations, the surface of the connecting drill bit continuously rotates with the ground to generate vibration energy, which can continuously push the buffer plate. At the same time, the buffer plate continuously compresses the connecting spring inside the connecting cylinder. After the connecting spring is compressed, it rebounds. The damping rod absorbs the rebounding energy of the connecting spring, so as to achieve the effect of absorbing the vibration energy on the surface of the connecting drill bit and ensure the service life of the connecting drill bit.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, in this implementation: An internal and external flipping anti-sticking drill bit includes a drill body 1. A connecting seat 2 is fixedly connected to the top end of the drill body 1. A flipping assembly 3 is movably connected to the top end of the connecting seat 2. A buffer assembly 4 is movably connected inside the connecting seat 2. A fixed seat 34 is fixedly connected to the top end of the connecting seat 2. A rotating block 33 is rotatably connected to one side of the fixed seat 34. A connecting drill bit 31 is fixedly connected to one side of the rotating block 33. Cutting teeth 32 are fixedly connected to the surface of the connecting drill bit 31. A first connecting block 35 is fixedly connected to the inner side of the connecting drill bit 31 shown. A rotating rod 36 is rotatably connected to one side of the first connecting block 35. One end of the rotating rod 36 is rotatably connected to a second connecting block 37. One end of the second connecting block 37 is fixedly connected to a movable plate 38. A clamping seat 39 located on the inner wall of the drill body 1 is slidably connected to one side of the movable plate 38. A fixing plate 312 is fixedly connected to the bottom end of the clamping seat 39. A hydraulic rod 311 is fixedly connected to the top end of the fixing plate 312. A lifting platform 310 is fixedly connected to the movable end of the hydraulic rod 311. By setting the flipping assembly 3, it is ensured that the sand and gravel generated during surface operation can be shunted within the spacing of the cutting teeth 32 of the connecting drill bit 31, effectively avoiding the accumulation of sand and gravel. At the same time, the hydraulic rod 311 pushes the lifting platform 310 to rise and fall. The lifting platform 310 drives the movable plate 38 and the second connecting block 37 to slide inside the clamping seat 39. At the same time, the rotating rod 36 on one side of the second connecting block 37 rotates to push the first connecting block 35 and the fixed seat 34 to move. The movement of the fixed seat 34 drives the connecting drill bit 31 to rotate along the position of the fixed seat 34 to achieve the flipping effect of the connecting drill bit 31, ensuring that the connecting drill bit 31 can eliminate the effect of sand sticking and jamming by changing its own shape.

[0025] In this embodiment, the buffer assembly 4 includes a buffer plate 41, a damping rod 42, a connecting spring 43, and a connecting cylinder 44. A connecting cylinder 44 is fixedly connected to the top end inside the connecting seat 2. The buffer plate 41 is slidably connected to the inner wall of the connecting cylinder 44. The damping rod 42 is fixedly connected to the bottom end of the buffer plate 41. The connecting spring 43 is fixedly connected to one side of the damping rod 42. By setting the buffer assembly 4, it is ensured that when the connecting drill bit 31 drills on the surface, the connecting drill bit 31 continuously impacts the buffer plate 41. The buffer plate 41 is under pressure and continuously compresses the connecting spring 43 inside the connecting cylinder 44. After the connecting spring 43 is compressed, it rebounds. The damping rod 42 absorbs the rebounding energy of the connecting spring 43 to achieve the buffering effect on the surface of the connecting drill bit 31, ensuring the service life of the device.

[0026] The number of connecting drill bits 31 is four groups. The positions of the connecting drill bits 31 are all on the same center of the circle. The connecting drill bits 31 are evenly distributed at an equal angle on one side of the drill body 1. It is ensured that when the connecting drill bits 31 operate on the surface to generate sand and gravel, the gaps between the cutting teeth 32 on the surface of the connecting drill bits 31 can disperse the sand and gravel, avoiding excessive accumulation of sand and gravel on the surface of the connecting drill bits 31.

[0027] The inside of the snap - on seat 39 is provided with a movable slot adapted to the size of the movable plate 38. The movable plate 38 is slidably connected to the inside of the snap - on seat 39 through the movable slot, ensuring that the hydraulic rod 311 pushing the lifting platform 310 can drive the movable plate 38 to slide inside the snap - on seat 39. At the same time, the rotating rod 36 on one side of the second connecting block 37 on one side of the movable plate 38 rotates to push the first connecting block 35 and the fixed seat 34 to move. The movement of the fixed seat 34 drives the connecting drill bit 31 to rotate along the position of the fixed seat 34 to achieve the flipping effect of the connecting drill bit 31.

[0028] The number of movable plates 38 is four groups. The positions of the movable plates 38 are co - centered. The movable plates 38 are evenly distributed at equal angles on the inner wall of the drill body 1, ensuring that the hydraulic rod 311 pushing the lifting platform 310 can flip the four groups of connecting drill bits 31 simultaneously, ensuring effective treatment of the accumulated grit on the surface of the connecting drill bits 31.

[0029] The number of connecting springs 43 is four groups. The positions of the connecting springs 43 are co - centered. The connecting springs 43 are evenly distributed at equal angles on one side of the damping rod 42, ensuring that the damping rod 42 can fully absorb the resilience energy of the connecting springs 43, ensuring effective vibration damping of the device at the connecting drill bit 31.

[0030] The inner wall of the connecting cylinder 44 is provided with a connecting slot adapted to the size of the buffer plate 41. The buffer plate 41 is slidably connected to the inner wall of the connecting cylinder 44 through the connecting slot, ensuring that when the connecting drill bit 31 performs drilling operations on the ground surface, the generated vibration energy continuously pushes the surface of the buffer plate 41. The buffer plate 41 slides on the inner wall of the connecting cylinder 44 and continuously compresses the connecting springs 43 to achieve the transmission effect of the vibration energy.

[0031] Working principle and usage process of the present utility model: The present utility model is an internal and external flipping anti-sticking drill bit. When anti-sticking treatment is required for the drill bit position of the device during use, the lifting platform 310 is lifted or lowered by the hydraulic rod 311. The lifting or lowering of the lifting platform 310 drives the movable plate 38 and the second connecting block 37 to slide inside the clamping seat 39. The movement of the second connecting block 37 drives the rotating rod 36 to rotate along the position of the second connecting block 37. At the same time, the rotation of the rotating rod 36 drives the first connecting block 35 and the fixed seat 34 to move. The movement of the fixed seat 34 drives the connecting drill bit 31 to rotate along the position of the fixed seat 34, enabling the drill bit to eliminate the effect of sand settling and sticking through flipping. At the same time, the gap between the cutting teeth 32 on the surface of the connecting drill bit 31 can further improve the efficiency of the device in eliminating sediment. At the same time, when protection for the connecting drill bit 31 is required, drilling operation is carried out by contacting the surface of the connecting drill bit 31 with the ground. At this time, the continuous rotation of the surface of the connecting drill bit 31 with the ground generates vibration energy that continuously pushes the buffer plate 41. At the same time, the buffer plate 41 continuously compresses the connecting spring 43 inside the connecting cylinder 44. After the connecting spring 43 is compressed, it rebounds, and the damping rod 42 absorbs the rebounding energy of the connecting spring 43, thereby achieving the effect of absorbing the vibration energy on the surface of the connecting drill bit 31 and ensuring the service life of the connecting drill bit 31.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
