Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of core drilling protection, in particular to a core drilling structure with anti-sticking and convenient cleaning. BACKGROUND

[0002] Core drilling is a common exploration method for solid mineral geological exploration. The cylindrical drill bit and drilling tool break the rock along the circumference at the bottom of the hole, leaving a columnar core at the center of the hole bottom. The core is taken out of the hole for geological and mineral research, hence the name core drilling.

[0003] The existing core drilling structure, such as the utility model patent with the patent number CN218324798U, discloses a core drilling structure with anti-sticking and convenient cleaning. The motor is used as the driving force. However, the motor needs to be powered through the cable arrangement. During the drilling process, the environment is humid and complex, which can easily cause cable wear and tear, electrical leakage, and safety accidents. In addition, the drill bit works in the ground and generates water and heat, which can further damage the motor. During the lifting of the drill bit, small sand and gravel can accumulate and move outward, causing the sidewall to be blocked and stuck, affecting the smooth extraction of the drill bit. Moreover, the drill bit is directly washed during cleaning, making it difficult to remove the adhering debris and resulting in poor cleaning effect. SUMMARY

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1-9 As shown, the present invention discloses a convenient and easy-to-clean anti-jamming core drilling and coring structure, comprising a frame 1, a drilling mechanism 2 mounted on the frame 1, an anti-jamming structure 3 mounted on the drilling mechanism 2, an anti-jamming mechanism 4 mounted on the drilling mechanism 2, a cleaning mechanism 5 mounted on the drilling mechanism 2, an adjusting mechanism 6 mounted on the cleaning mechanism 5, and a flushing mechanism 7 mounted on the cleaning mechanism 5.

[0031] Specifically, the drilling mechanism 2 includes a connecting rod 201, which is installed at the center of the frame 1. A connecting seat 202 is detachably installed at the bottom of the connecting rod 201. A second drill bit 204 is installed at the bottom of the connecting seat 202. A first annular drill bit 203 is engaged at the top edge of the connecting seat 202. Multiple locking pins 205 are threaded onto the top side wall of the connecting seat 202. One end of each locking pin 205 engages with the inside of the first drill bit 203. The installation of the connecting rod 201 facilitates the detachable connection of the connecting seat 202. The connecting seat 202 facilitates the installation of the second drill bit 204, which is beneficial for drilling operations. The connecting rod 201 is driven by the equipment on the frame 1, thereby driving the connecting seat 202 and the second drill bit 204 to rotate, and making the drill bit contact the rock formation for drilling. After drilling is completed, the lifting of the connecting seat 202, combined with the rotation of the first drill bit 203, helps to break up the sand and gravel debris on the top edge of the connecting seat 202, making it easy to smoothly pull out the connecting seat 202.

[0032] Specifically, a column 206 is installed at the center of the top of the second drill bit 204. The column 206 extends into the interior of the connecting seat 202 and is rotatably connected to the interior of the connecting seat 202. The second drill bit 204 is rotatably connected to the bottom of the connecting seat 202 via the column 206. The column 206 has a "T"-shaped structure and is slidably connected to the interior of the connecting seat 202 via multiple compression springs 209. Multiple equidistantly distributed ring-shaped limiting blocks 208 are fixedly connected to the top of the second drill bit 204. Block 208 is slidably connected to the inner bottom of the connecting seat 202. Under the action of the column 206, it is beneficial to install the second drill bit 204 at the bottom of the connecting seat 202. Under the action of the compression spring 209, the column 206 slides, and the multiple limiting blocks 208 separate from the inside of the connecting seat 202, so that the second drill bit 204 will not rotate with the connecting seat 202. This is beneficial to enable the sun gear 304 on the column 206 to drive the multiple planetary gears 302, so as to realize the rotation of the helical rod 301.

[0033] Specifically, a guide plate 207 is vertically fixedly connected to the top edge of the second drill bit 204. The guide plate 207 has a circular structure, and its top is slidably connected to the inside of the connecting seat 202. The top edge of the second drill bit 204 has a certain slope. The installation of the guide plate 207 helps to shield and protect the gap between the connecting seat 202 and the second drill bit 204, preventing sand and gravel debris from entering and causing the connecting seat 202 and the second drill bit 204 to not fit tightly together.

[0034] Specifically, the anti-jamming structure 3 includes a helical rod 301. Multiple vertically arranged helical rods 301 are rotatably connected to the top of the connecting seat 202. The bottoms of the multiple helical rods 301 extend into the interior of the connecting seat 202. Planetary gears 302 are fixedly connected to the bottoms of the multiple helical rods 301 respectively. A sun gear 304 is rotatably connected to the center of the connecting seat 202. The multiple planetary gears 302 mesh with the sun gear 304 respectively. A drive rod 303 is installed on the top of the column 206. The drive rod 303 is slidably connected to the sun gear 304. The drive rod 303 has a hexagonal prism structure and is connected to the sun gear 304 by the multiple helical rods 301. Under the action of the swivel rod 301, the sand and gravel accumulated on the top of the connecting seat 202 are rolled towards the middle, so that when the connecting seat 202 is lifted, a large amount of sand and gravel will not enter the hole gap and cause jamming, making it impossible to lift and pull out the connecting seat 202. When the connecting seat 202 and the sun gear 304 rotate, multiple planetary gears 302 and the sun gear 304 rotate, thereby causing multiple swivel rods 301 to rotate. Through the sliding of the drive rod 303 and the sun gear 304, the drive rod 303 can be positioned and slid on the sun gear 304, realizing the engagement and disengagement of the second drill bit 204.

[0035] Specifically, the abutting mechanism 4 includes push rods 402. Multiple push rods 402 arranged in a ring are installed at the inner edge of the second drill bit 204. The push rods 402 are slidably connected to the inside of the second drill bit 204 via compression springs 404. A slider 403 is installed at one end of each of the push rods 402, extending to the outside of the second drill bit 204. Multiple grooves 406 arranged in a ring are provided on the bottom sidewall of the connecting seat 202. Multiple top blocks 407 arranged in a ring are slidably connected inside the second drill bit 204. A connecting spring 405 connects the top blocks 407 to the push rods 402. One end of each top block 407 has an arc-shaped structure and abuts against the inside of the groove 406. Under the action of the groove 406, the top blocks 407 retract. Under the action of the compression springs 404, the push rods 402 drive the sliders 403 to retract inside the second drill bit 204, thereby facilitating... During the drilling operation, the second drill bit 204 rotates and, after disengaging from the connecting seat 202, the groove 406 on the side wall of the connecting seat 202 drives the top block 407 to abut. The top block 407 then drives the connecting spring 405 to drive the top rod 402, causing the top rod 402 to slide free from the action of the compression spring 404. This allows the slider 403 to slide out and abut against the rock formation, effectively limiting the second drill bit 204 from rotation and increasing the torque of the auger rod 301. Simultaneously, the slider 403 can slide up and down against the rock formation, facilitating the sliding lifting and removal of the connecting seat 202 and the second drill bit 204. Under the action of the connecting spring 405, the top block 407 and the top rod 402 have elasticity, allowing the top block 407 to continue sliding after the slider 403 abuts, thus disengaging the connecting seat 202 from the second drill bit 204.

[0036] Specifically, one side wall of the slider 403 has an arc-shaped structure, and guide wheels 401 are rotatably connected to multiple sliders 403. The guide wheels 401 extend to the outside of the second drill bit 204, which facilitates the smooth sliding of the slider 403 with the rock strata. Under the action of the guide wheels 401, the second drill bit 204 slides up and down smoothly, but is not easy to rotate.

[0037] Specifically, the cleaning mechanism 5 includes a mounting base 502. The bottom of the frame 1 is fixedly connected to symmetrical mounting bases 502. Symmetrical clamping plates 501 are installed on the two mounting bases 502. Brushes 503 are respectively installed on the two clamping plates 501. The clamping plates 501 have a "T" shaped structure and one end of the clamping plate 501 has an arc-shaped structure. The two mounting bases 502 facilitate the installation of the two clamping plates 501 and the connection of the brushes 503, thereby facilitating the removal of dust and debris adhering to the connecting seat 202 and the second drill bit 204 without causing wear to the second drill bit 204.

[0038] Specifically, the adjustment mechanism 6 includes a drive shaft 602, which is rotatably connected to the bottom of the frame 1. Both ends of the drive shaft 602 extend into the interior of both sides of the frame 1. Bevel gears 604 are fixedly connected to both ends of the drive shaft 602. A stepper motor 601 is detachably connected to one side of the frame 1. The output shaft of the stepper motor 601 is connected to one end of the drive shaft 602. Transmission rods 606 are rotatably connected to the interior of both sides of the bottom of the frame 1. Drive gears 605 are respectively installed at both ends of the two transmission rods 606, and the two drive gears 605 mesh perpendicularly with the two bevel gears 604. Screws 603 are rotatably connected inside the two mounting seats 502. The screws 603 extend into the interior of the clamping plate 501 and are threadedly connected to the interior of the clamping plate 501. One end of each screw 603... Extending into the frame 1, two screws 603 are fitted with bevel gears 604 at one end. The two bevel gears 604 mesh with two other drive gears 605. The clamping plate 501 is slidably connected to the mounting base 502 via the screws 603. The installation of the screws 603 facilitates the sliding of the clamping plate 501. The operation of the stepper motor 601 facilitates the rotation of the drive shaft 602. The drive shaft 602 drives the two transmission rods 606 to rotate via the two bevel gears 604. The drive gears 605 on the transmission rods 606 drive the other two bevel gears 604 to rotate, thereby causing the two screws 603 to rotate synchronously. The two screws 603 allow the two clamping plates 501 to slide and adjust their positions, facilitating the scraping and cleaning of the second drill bit 204 of different sizes.

[0039] Specifically, the rinsing mechanism 7 includes nozzles 703. Multiple nozzles 703 arranged in a ring are installed on one side of each of the two clamping plates 501. A water storage tank 707 is provided inside the two clamping plates 501. One end of each nozzle 703 extends into the water storage tank 707. A water inlet groove 705 is provided inside the two clamping plates 501, communicating with the water storage tank 707. A conveying pipe 706 is connected to the sidewall of the two clamping plates 501, with one end connected to the water inlet groove 705. A movable groove 704 is provided on the sidewall of the mounting base 502, through which the conveying pipe 706 slides. The frame 1 is connected to a water tank 701 at its bottom. A water inlet pipe 702 is installed on the water tank 701. Two delivery pipes 706 extend to the inner bottom of the water tank 701. The installation of the water tank 701 facilitates water storage. The water inlet pipe 702 facilitates water filling into the water tank 701. The water pump inside the water tank 701 works to transport water through the delivery pipes 706 to the water storage tank 707. The pressurized water is sprayed out through multiple nozzles 703, which facilitates the high-pressure water spray to clean the second drill bit 204 and wash away debris.

[0040] In use, the installation of the connecting rod 201 facilitates the detachable connection of the connecting seat 202. The connecting seat 202 facilitates the installation of the second drill bit 204, enabling drilling operations. The connecting rod 201, driven by the equipment on the frame 1, rotates the connecting seat 202 and the second drill bit 204, causing the drill bit to contact the rock formation for drilling. After drilling, the lifting of the connecting seat 202, combined with the rotation of the first drill bit 203, helps to break up sand and gravel particles at the top edge of the connecting seat 202, as well as particles protruding from the inner wall of the hole, facilitating the smooth extraction of the connecting seat 202. The column 206 further facilitates the installation of the second drill bit 204 onto the connecting seat 202. At the bottom, under the action of the compression spring 209, the column 206 slides, and multiple limiting blocks 208 separate from the interior of the connecting seat 202, preventing the second drill bit 204 from rotating with the connecting seat 202. This facilitates the driving of the sun gear 304 on the column 206 onto multiple planetary gears 302, enabling the spiral rod 301 to rotate. The installation of the guide plate 207 helps to shield and protect the gap between the connecting seat 202 and the second drill bit 204, preventing sand and gravel debris from entering and causing the connecting seat 202 and the second drill bit 204 to not fit tightly. Through the rotation of the multiple spiral rods 301, the sand and gravel at the top of the connecting seat 202 are rolled towards the center, making it less likely for sand and gravel particles to get stuck between the connecting seat and the rock strata. The lower connecting seat 202 is then pulled out. When the connecting seat 202 rotates with the sun gear 304, multiple planetary gears 302 and the sun gear 304 rotate, thereby causing multiple helical rods 301 to rotate. The sliding of the drive rod 303 with the sun gear 304 facilitates the positioning and sliding of the drive rod 303 on the sun gear 304, enabling the engagement and disengagement of the second drill bit 204. Under the action of the groove 406, the top block 407 retracts, and under the action of the compression spring 404, the top rod 402 drives the slider 403 to retract inside the second drill bit 204, facilitating the rotation of the second drill bit 204 for drilling operations. After the second drill bit 204 disengages from the connecting seat 202, the groove 406 on the side wall of the connecting seat 202 drives the top block 407 to abut, and the top block 407 drives the connecting spring 405. Driven by the push rod 402, it slides away from the pressure spring 404, allowing the slider 403 to slide out and contact the rock layer. This facilitates smooth up-and-down sliding of the second drill bit 204, preventing it from rotating easily. This increases the torque of the auger rod 301, improving the sand and gravel collection effect. Simultaneously, the slider 403 can slide up and down with the rock layer, facilitating the sliding lifting and removal of the connecting seat 202 and the second drill bit 204. Under the action of the connecting spring 405, the push block 407 and the push rod 402 have elasticity, allowing the push block 407 to continue sliding after the slider 403 contacts the rock layer. This disengages the connecting seat 202 from the second drill bit 204, ensuring smooth sliding of the slider 403 with the rock layer and reducing the risk of jamming. The guide wheel 401 further enhances this effect.The sliding mechanism of slider 403 is made smoother and more stable, with better guiding effect. The two mounting seats 502 facilitate the installation of the two clamping plates 501, and the clamping plates 501 facilitate the connection of brush 503. This makes it easier to wipe away dust and debris from connecting seat 202 and second drill bit 204 without causing wear to the second drill bit 204. The installation of screw 603 facilitates the sliding of clamping plates 501. The operation of stepper motor 601 facilitates the rotation of drive shaft 602. Drive shaft 602 drives two transmission rods 606 to rotate via two bevel gears 604. The drive gear 605 on the 06 drives two other bevel gears 604 to rotate, thereby causing the two screws 603 to rotate synchronously. The two screws 603 allow the two clamping plates 501 to slide and adjust their positions, facilitating the scraping and cleaning of second drill bits 204 of different sizes. The installation of the water tank 701 facilitates water storage. Water is easily added to the water tank 701 via the inlet pipe 702. The water pump inside the water tank 701 transports water through the delivery pipe 706 to the water storage tank 707, and the pressurized water is sprayed out through multiple nozzles 703, which is beneficial for cleaning the second drill bit 204, washing away debris and impurities.
