Description

Technical Field

[0001] This invention relates to the field of drill bit technology, specifically to a mining roller cone drill bit that is easy to assemble. Background Technology

[0002] Mining roller cone drill bits are drilling tools widely used in mining, geological exploration, and oil and gas drilling, primarily for drilling into hard strata such as rock and ore. They break rocks through the rotation and impact of the roller cones, making them one of the key rock-breaking devices in mining operations.

[0003] After prolonged operation, existing mining roller cone drill bits may corrode or become obstructed in rotation, necessitating component replacement. Currently, drill bit replacement is a rather cumbersome process, hence the new design addressing this issue. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a mining roller cone drill bit that is easy to assemble, comprising a drill bit device, wherein a spraying device is fixedly connected to one side of the external output end of the drill bit device, and a buffer device is fixedly connected to the external side of the drill bit device away from the spraying device.

[0005] The drill bit assembly includes a body. The middle of one side of the body is fixedly connected to the outer side of a spraying device. The spraying device is connected to a water supply pipe, and the spraying device flushes the components with liquid, which cools and dissipates heat, reduces friction between the drill bit and the workpiece / rock cuttings, and prevents cutting material from adhering to the drill bit, thus maintaining normal equipment operation. A drill bit block is fixedly connected to the side of the body near the spraying device. A drive device controls the rotation of the drill rod, causing the body to drive the drill bit block to rotate against the ground, thereby achieving the function of drilling and breaking the soil. The side of the body away from the drill bit block is fixedly connected to the outer side of a buffer device. A drill bit housing is fixedly connected to one side of the body. When the drill bit contacts the ground, a buffer device acts as a shock absorber, absorbing the impact load during drilling and providing a certain degree of protection for the equipment components. During equipment operation, a drill rod is inserted into the inner side of the drill bit housing. The drill rod is inserted into the inner side of the drill bit housing, and a hydraulic sliding block is used to engage the block with a square groove, thereby securing the components and facilitating assembly and disassembly to meet subsequent equipment requirements. A locking block is slidably connected to the outer side of the drill rod near the drill bit housing. A square groove is provided on the inner side of the drill bit housing, and the outer side of the locking block engages with the inner side of the square groove.

[0006] Preferably, an annular base is fixedly connected to the outer side of the drill bit housing away from the buffer device. An anti-detachment mechanism is fixedly connected to the outer side of the annular base. When the drill rod docks with the inner side of the drill bit housing, it impacts the anti-impact mechanism, which acts as a shock absorber and buffer to reduce collisions between components and avoid affecting the docking accuracy. The anti-detachment mechanism is engaged with the outer side of the drill rod to fix the component, further improving the stability of the component and preventing it from falling off during operation. This avoids affecting the efficiency and accuracy of subsequent operations and keeps the equipment running normally. The anti-impact mechanism is slidably connected to the inner wall of the drill bit housing near the buffer device.

[0007] Preferably, the anti-impact mechanism includes an anti-impact plate, and a sliding rod is fixedly connected to one side of the outer side of the anti-impact plate. The outer side of the sliding rod is slidably connected to the bottom of the inner wall of the drill bit housing. When the drill rod docks with the drill bit housing, the drill rod impacts the anti-impact plate, causing the anti-impact plate to drive the sliding rod to compress and contract the first spring, thereby achieving the effect of shock absorption and buffering, reducing the impact pressure on the components, reducing rigid collisions between components, thereby slowing down the wear between components and extending the service life of the components. The first spring is sleeved on the outer side of the sliding rod near the anti-impact plate, and a silicone block is fixedly connected to the outer side of the anti-impact plate away from the first spring. The silicone block is made of silicone material, which provides a certain degree of wear resistance and buffering, and provides a certain degree of protection for the components, increasing the wear resistance between components and further improving the buffering effect.

[0008] Preferably, the anti-detachment mechanism includes an anti-detachment housing, the outer side of which is fixedly connected to the outer side of the annular base. An electric push rod is fixedly connected to the inner wall of the anti-detachment housing, and an anti-detachment block is fixedly connected to one side of the electric push rod. The anti-detachment housing serves to block soil and reduce the entry of external impurities. The electric push rod controls the anti-detachment block to align with the groove on the outer side of the drill rod, thereby increasing the fixing force between the components and further improving the stability between the components. This prevents detachment during subsequent rotation operations and avoids affecting the operating efficiency of the components.

[0009] Preferably, a rubber block is fixedly connected to the side of the anti-detachment block away from the electric push rod. The rubber block acts as a shock absorber and buffer, reducing wear between components and preventing excessive squeezing force that could damage the components, thereby extending the service life of the components. A cutout is provided on one side of the outer surface of the rubber block. By creating the cutout and groove, the surface texture of the components is increased, thereby improving the surface friction performance of the components and further improving the clamping effect on the components. At the same time, the groove also provides a certain degree of protection.

[0010] Preferably, the buffer device includes a receiving plate, and a buffer housing is fixedly connected to the outer side of the receiving plate near the drill bit housing. A second spring is provided on the inner side of the buffer housing. When the drill bit device contacts the ground, the component is subjected to the ground reaction force, causing the connecting rod to slide inward to the buffer housing and compress the second spring, thereby playing a role in shock absorption and buffering. On the one hand, it reduces vibration and impact load by absorbing or dissipating impact energy through elastic deformation or damping, reducing the vibration amplitude. On the other hand, it extends tool life and reduces costs. By reducing vibration, impact, and stress damage, the buffer mechanism can significantly extend the service life of the drill bit, reduce the frequency of tool replacement, reduce processing costs, and reduce damage to the drill rod and equipment. By blocking or weakening the transmission of the impact received by the drill bit to the drill rod and drilling machine, it reduces the fatigue fracture of the drill rod, thereby maintaining the normal operation of the equipment. A connecting rod is fixedly connected to the outer side of the second spring, and the outer side of the connecting rod is slidably connected to the inner side of the buffer housing. A receiving base plate is fixedly connected to the outer side of the connecting rod away from the second spring, and the outer side of the receiving base plate is fixedly connected to the outer side of the machine body. A braking mechanism is fixedly connected to the outer side of the buffer housing.

[0011] Preferably, the braking mechanism includes a brake housing, the outer side of which is fixedly connected to the outer side of the buffer housing. When the drill bit device stops operating and rises, the second spring rebounds. Rapid rebound can easily increase the mechanical wear of the components, thereby affecting their service life, and can also easily increase the rapid vibration of the components. The stored elastic potential energy will be released instantaneously in the form of kinetic energy, which may cause severe impact on the equipment components or contact surfaces, accelerating component wear and fatigue. When the spring rebounds rapidly, the parts in contact with it will be subjected to repeated impact loads, resulting in wear, indentation, or cracks on the contact surfaces. An outer block is slidably connected to the inner side of the brake housing, and the outer side of the outer block is fixedly connected to the outer side of the connecting rod. When the second spring rebounds rapidly, it drives the outer block to squeeze the third spring inside the brake housing, thereby achieving the effect of braking the rebound speed, thereby reducing the vibration frequency of the components, reducing wear between components, and providing a certain protective effect for the components. The third spring is provided on the inner side of the brake housing.

[0012] Preferably, the spraying device includes a spraying base, which is located on the outside of the machine body. Water flows through the spraying base to flush the drill bit and soil, achieving efficient heat dissipation and cooling to prevent material softening, increased wear, or structural failure caused by high temperatures. It also lubricates, reduces friction, and prevents soil adhesion to the outside of the drill bit, thus avoiding affecting the efficiency of component rotation and drilling, increasing soil moisture, and reducing drilling difficulty. One side of the spraying base is fixedly connected to the outside of the machine body. A first funnel cover is fixedly connected to the side of the spraying base away from the machine body, and a second funnel cover is fixedly connected to the side of the spraying base close to the first funnel cover. The distance between the first and second funnel covers prevents external impurities from entering. External impurities directly block the holes on the surface of the components. When the first funnel cover is blocked, water flows outward through the second funnel cover to flush the first funnel cover, thus maintaining continuous operation of the equipment and reducing the probability of component blockage. A rotating mechanism is fixedly connected to the inside of the second funnel cover.

[0013] Preferably, the rotating mechanism includes a fixed frame, a support shaft is fixedly connected to the inner side of the fixed frame, a rotating column is rotatably connected to the outer side of the support shaft, a fan blade is fixedly connected to one side of the outer side of the rotating column, and a scraper is fixedly connected to the outer side of the rotating column away from the fan blade. The fan blade is impacted by the water flow, causing the fan blade to control the rotation of the rotating column. The rotating column drives the scraper to rotate, thereby scraping the inner wall of the component, cleaning up excess impurities, reducing impurity accumulation, preventing impurities from accumulating and clumping, and preventing them from affecting the subsequent liquid flow effect.

[0014] This invention provides a mining roller cone drill bit that is easy to assemble. It has the following beneficial effects:

[0015] I. This easily assembled mining roller cone drill bit features a drill bit assembly design where the drill rod is inserted into the inner side of the drill bit housing. A hydraulic sliding block on the drill rod engages with a square groove, securing the components and facilitating assembly and disassembly to meet subsequent equipment requirements. A drive unit controls the rotation of the drill rod, causing the drill bit to rotate against the ground, thus achieving the drilling and soil breaking action. A buffer device absorbs shocks and impact loads during drilling when the drill bit contacts the ground, providing some protection for the equipment components. During operation, a spraying device is connected to a water supply pipe. The system uses a spraying device to flush the components with liquid, which cools and dissipates heat while reducing friction between the drill bit and the workpiece / rock cuttings, preventing cutting material from sticking to the drill bit and ensuring normal equipment operation. When the drill rod mates with the inner side of the drill bit housing, it impacts the anti-impact mechanism, which acts as a shock absorber to reduce collisions between components and avoid affecting the assembly accuracy. The anti-detachment mechanism engages with the outer side of the drill rod to fix the components, further improving their stability and preventing them from falling off during operation, thus avoiding affecting subsequent operation efficiency and accuracy and ensuring normal equipment operation.

[0016] II. This easily assembled mining roller cone drill bit features an anti-impact mechanism. When the drill rod mates with the drill bit housing, the drill rod impacts the anti-impact plate, causing the anti-impact plate to drive the sliding rod to compress and contract the first spring. This achieves shock absorption and buffering, reducing impact pressure on components and minimizing rigid collisions between components. This slows down wear and extends the service life of the components. The silicone block is made of silicone, which provides wear resistance and cushioning, protecting the components, increasing wear resistance, and further enhancing the buffering effect.

[0017] Third, this easy-to-assemble mining roller cone drill bit features an anti-detachment mechanism. The anti-detachment shell acts as a barrier against soil, reducing the entry of external impurities. An electric push rod controls the anti-detachment block to engage with the groove on the outside of the drill rod, increasing the fixing force between components and further improving their stability. This prevents detachment during subsequent rotation operations, ensuring operational efficiency. Rubber blocks act as shock absorbers, reducing wear between components and preventing excessive pressure that could damage them, thus extending their service life. Furthermore, the presence of faceted cuts and grooves increases surface texture, improving surface friction and enhancing clamping effectiveness. The grooves also provide some protection.

[0018] IV. This easily assembled mining roller cone drill bit, through its buffer device design, when the drill bit assembly contacts the ground, the components are subjected to ground reaction force, causing the connecting rod to slide inwards towards the buffer housing, compressing and contracting the second spring, thereby playing a role in shock absorption and buffering. On the one hand, it reduces vibration and impact loads by absorbing or dissipating impact energy and reducing vibration amplitude through elastic deformation or damping. On the other hand, it extends tool life and reduces costs. By reducing vibration, impact, and stress damage, the buffer mechanism can significantly extend the service life of the drill bit, reduce the frequency of tool replacement, reduce processing costs, and reduce damage to the drill rod and equipment. By blocking or weakening the transmission of impact received by the drill bit to the drill rod and drilling rig, it reduces fatigue fracture of the drill rod, thereby maintaining the normal operation of the equipment.

[0019] V. This easily assembled mining roller cone drill bit features a spray device designed for external use. Water flows through the spray base to flush the drill bit and soil, effectively cooling the material and preventing softening, increased wear, or structural failure due to high temperatures. It also lubricates, reduces friction, and prevents soil adhesion, minimizing soil buildup and ensuring efficient drilling. This increases soil moisture and reduces drilling difficulty. The distance between the first and second funnel covers prevents external impurities from entering, directly clogging the surface pores. When the first funnel cover is clogged, water is sprayed outwards through the second funnel cover to flush it, ensuring continuous operation and reducing the probability of component blockage.

[0031] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a mining roller cone drill bit that is easy to assemble, including a drill bit device 1, a spraying device 3 fixedly connected to one side of the external output end of the drill bit device 1, and a buffer device 2 fixedly connected to the external side of the drill bit device 1 away from the spraying device 3.

[0032] The drill bit device 1 includes a body 11. The middle of one side of the body 11 is fixedly connected to the outside of the spraying device 3. A drill bit block 18 is fixedly connected to the side of the body 11 near the spraying device 3. The side of the body 11 away from the drill bit block 18 is fixedly connected to the outside of the buffer device 2. A drill bit housing 12 is fixedly connected to the side of the buffer device 2 away from the body 11. A drill rod 13 is inserted into the inside of the drill bit housing 12. A locking block 14 is slidably connected to the side of the drill rod 13 near the drill bit housing 12. A square groove 17 is provided on the inside of the drill bit housing 12. The outside of the locking block 14 is engaged with the inside of the square groove 17. The drill rod 13 is inserted into the inner side of the drill bit housing 12. The drill rod 13 is hydraulically slidable by the locking block 14, which aligns with the square groove 17 to secure the components. This facilitates assembly and disassembly, meeting the subsequent needs of the equipment. The drill rod 13 is rotated by the drive device, causing the machine body 11 to rotate the drill bit 18 against the ground, thus achieving the function of drilling. When the drill bit 18 contacts the ground, the buffer device 2 acts as a shock absorber, absorbing the impact load during drilling and providing a certain degree of protection for the equipment components. During equipment operation, the spraying device 3 is connected to a water supply pipe, which sprays liquid to flush the components. This serves to cool and dissipate heat, and also reduces friction between the drill bit and the workpiece or rock cuttings, preventing cutting material from sticking to the drill bit, thereby maintaining the normal operation of the equipment.

[0033] An annular base 15 is fixedly connected to the outer side of the drill bit housing 12 away from the buffer device 2. An anti-detachment mechanism 19 is fixedly connected to the outer side of the annular base 15. An anti-impact mechanism 16 is slidably connected to the inner wall of the drill bit housing 12 near the buffer device 2. When the drill rod 13 mates with the inner side of the drill bit housing 12, it impacts the anti-impact mechanism 16, which acts as a shock absorber to reduce collisions between components and avoid affecting the assembly accuracy. The anti-detachment mechanism 19 engages with the outer side of the drill rod 13 to fix the components, further improving their stability, preventing them from falling off during operation, avoiding affecting subsequent operation efficiency and accuracy, and maintaining normal equipment operation.

[0034] The anti-impact mechanism 16 includes an anti-impact plate 161. A sliding rod 163 is fixedly connected to one side of the outer side of the anti-impact plate 161. The outer side of the sliding rod 163 is slidably connected to the bottom of the inner wall of the drill bit housing 12. A first spring 164 is sleeved on the outer side of the sliding rod 163 near the anti-impact plate 161. A silicone block 162 is fixedly connected to the outer side of the anti-impact plate 161 away from the first spring 164. When the drill rod 13 docks with the drill bit housing 12, the drill rod 13 impacts the anti-impact plate 161, causing the anti-impact plate 161 to drive the sliding rod 163 to compress and contract the first spring 164, thereby achieving a shock absorption and buffering effect, reducing the impact pressure on the components, reducing rigid collisions between components, thereby slowing down wear between components and extending the service life of the components. The silicone block 162 is made of silicone, which provides a certain degree of wear resistance and buffering, and provides a certain degree of protection for the components, increasing the wear resistance between components and further improving the buffering effect.

[0035] The anti-detachment mechanism 19 includes an anti-detachment housing 191, the outer side of which is fixedly connected to the outer side of the annular base 15. An electric push rod 192 is fixedly connected to the inner wall of the anti-detachment housing 191, and an anti-detachment block 193 is fixedly connected to one side of the electric push rod 192. The anti-detachment housing 191 serves to block soil and reduce the entry of external impurities. The electric push rod 192 controls the anti-detachment block 193 to engage with the groove on the outer side of the drill rod 13, thereby increasing the fixing force between the components and further improving the stability between the components. This prevents detachment during subsequent rotation operations and avoids affecting the operating efficiency of the components.

[0036] A rubber block 194 is fixedly connected to the side of the anti-detachment block 193 away from the electric push rod 192. A slit 195 is opened on the outer side of the rubber block 194. The rubber block 194 plays a role in shock absorption and cushioning, reducing wear between components, avoiding excessive squeezing force that could damage the components, and thus extending the service life of the components. Secondly, by opening the slit 195, the groove is made to increase the surface texture of the components, thereby improving the surface friction performance of the components and further improving the clamping effect on the components. At the same time, the groove also provides a certain degree of protection.

[0037] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7As shown, the buffer device 2 includes a receiving plate 21. A buffer housing 22 is fixedly connected to the outside of the receiving plate 21 near the drill bit housing 12. A second spring 24 is provided on the inside of the buffer housing 22. A connecting rod 23 is fixedly connected to the outside of the second spring 24. The outside of the connecting rod 23 is slidably connected to the inside of the buffer housing 22. A receiving base plate 26 is fixedly connected to the outside of the connecting rod 23 away from the second spring 24. The outside of the receiving base plate 26 is fixedly connected to the outside of the machine body 11. A braking mechanism 25 is fixedly connected to the outside of the buffer housing 22. When the drill bit assembly 1 contacts the ground, the components are subjected to ground reaction force, causing the connecting rod 23 to slide inward toward the buffer housing 22 and compress the second spring 24, thereby playing a role in shock absorption and buffering. On the one hand, it reduces vibration and impact load by absorbing or dissipating impact energy through elastic deformation or damping, thus reducing the vibration amplitude. On the other hand, it extends tool life and reduces costs. By reducing vibration, impact, and stress damage, the buffer mechanism can significantly extend the service life of the drill bit, reduce the frequency of tool replacement, reduce processing costs, and reduce damage to the drill rod 13 and equipment. By blocking or weakening the transmission of impact from the drill bit to the drill rod 13 and drilling rig, it reduces fatigue fracture of the drill rod, thereby maintaining the normal operation of the equipment.

[0038] The braking mechanism 25 includes a brake housing 251. The outer side of the brake housing 251 is fixedly connected to the outer side of the buffer housing 22. An outer block 252 is slidably connected to the inner side of the brake housing 251. The outer side of the outer block 252 is fixedly connected to the outer side of the connecting rod 23. A third spring 253 is provided on the inner side of the brake housing 251. When the drill bit device 1 stops operating and rises, the second spring 24 rebounds. Rapid rebound can easily increase the mechanical wear of the components, thereby affecting the service life of the components, and can easily increase the rapid vibration of the components. The stored elastic potential energy will be released instantaneously in the form of kinetic energy, which may cause severe impact on the equipment components or contact surfaces, accelerating component wear and fatigue. When the spring rebounds rapidly, the parts in contact with it will be subjected to repeated impact loads, resulting in wear, indentation or cracks on the contact surface. When the second spring 24 rebounds rapidly, it drives the outer block 252 to squeeze the third spring 253 on the inner side of the brake housing 251, thereby achieving the effect of braking the rebound speed, thereby reducing the vibration frequency of the components, reducing the wear between components, and providing a certain protective effect for the components.

[0039] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9As shown, the spraying device 3 includes a spraying base 31. One side of the spraying base 31 is fixedly connected to the outside of the body 11. A first funnel cover 32 is fixedly connected to the outside of the spraying base 31 away from the body 11. A second funnel cover 33 is fixedly connected to the outside of the spraying base 31 near the first funnel cover 32. A rotating mechanism 34 is fixedly connected to the inside of the second funnel cover 33. The spraying device 3 is located on the outside of the machine body 11. Water flows through the spraying base 31 to flush the drill bit block 18 and the soil. On the one hand, it can efficiently dissipate heat and cool down, avoiding material softening, accelerated wear or structural failure caused by high temperature. On the other hand, it can lubricate, reduce friction and prevent adhesion, reducing soil adhesion to the outside of the drill bit block 18, avoiding affecting the efficiency of component rotation and drilling, increasing soil moisture and reducing drilling difficulty. The distance between the first funnel cover 32 and the second funnel cover 33 can block the entry of external impurities. External impurities directly block the holes on the surface of the components. When the first funnel cover 32 is blocked, water flows out through the second funnel cover 33 to flush the first funnel cover 32, thereby maintaining continuous operation of the equipment and reducing the probability of component blockage.

[0040] The rotating mechanism 34 includes a fixed frame 341, a support shaft 342 fixedly connected to the inner side of the fixed frame 341, a rotating column 343 rotatably connected to the outer side of the support shaft 342, a fan blade 344 fixedly connected to one side of the rotating column 343, and a scraper 345 fixedly connected to the outer side of the rotating column 343 away from the fan blade 344. Water flow impacts the fan blade 344, causing it to control the rotation of the rotating column 343. The rotating column 343 then drives the scraper 345 to rotate, thereby scraping the inner wall of the component, cleaning away excess impurities, reducing impurity accumulation, preventing impurities from clumping together, and preventing them from affecting the subsequent liquid flow.

[0041] In use, one end of the drill rod 13 is connected to the drive mechanism, and the other end is docked with the drill bit housing 12. The hydraulic sliding block 14 of the drill rod 13 docks with the inner side of the square groove 17 to achieve the function of locking the components. By locking the components, the components can be quickly disassembled and assembled to meet the needs of subsequent operations. When the drill rod 13 docks with the inner side of the drill bit housing 12, the drill rod 13 comes into contact with the anti-impact mechanism 16. The anti-impact mechanism achieves the function of shock absorption and buffering, reducing the impact pressure of the components and reducing the rigid collision between the components, thereby slowing down the wear between the components and extending the service life of the components. The silicone block 162 is made of silicone material, which provides a certain degree of wear resistance and buffering. The silicone material provides a certain degree of protection for the components, increases the wear resistance between the components, and further improves the buffering effect. After the components are initially docked quickly, the anti-detachment mechanism 19 docks with the groove on the outside of the drill rod 13. The anti-detachment mechanism 19 increases the fixing force between the components, thereby further improving the stability between the components and preventing them from falling off during subsequent rotation operations, thus preventing the impact on the operating efficiency of the components.

[0042] When the drill bit assembly 1 contacts the soil surface or during drilling, the buffer device 2 acts as a shock absorber. On one hand, it reduces vibration and impact loads by absorbing or dissipating impact energy through elastic deformation or damping, thus reducing vibration amplitude. On the other hand, it extends tool life and reduces costs. By reducing vibration, impact, and stress damage, the buffer mechanism can significantly extend the life of the drill bit, reduce tool replacement frequency, lower processing costs, and reduce damage to the drill rod 13 and equipment. By blocking or weakening the transmission of impact from the drill bit to the drill rod 13 and drilling rig, it reduces fatigue fracture of the drill rod, thereby maintaining normal equipment operation. Furthermore, during drilling with the drill bit assembly 1, a water pipe is connected to the side of the machine body 11 near the buffer device 2, allowing water to flow... Water is sprayed outward from the spraying device 3, and the water flow passes through the spraying base 31 to flush the drill bit block 18 and the soil. On the one hand, it provides efficient heat dissipation and cooling, preventing material softening, accelerated wear, or structural failure caused by high temperatures. On the other hand, it lubricates, reduces friction, and prevents adhesion, reducing soil adhesion to the outside of the drill bit block 18, thus avoiding affecting the efficiency of component rotation and drilling, increasing soil moisture, and reducing drilling difficulty. The distance between the first funnel cover 32 and the second funnel cover 33 serves to block the entry of external impurities. External impurities directly block the holes on the surface of the components. When the first funnel cover 32 is blocked, water is sprayed outward through the second funnel cover 33 to flush the first funnel cover 32, thereby maintaining continuous operation of the equipment and reducing the probability of component blockage.
