Description

Technical Field

[0001] This application relates to the field of core exploration equipment technology, and in particular to a core segmentation marking device and marking method. Background Technology

[0002] In geological exploration, rock cores play a crucial role. They are cylindrical rock samples extracted from a borehole using a ring core drill bit and other core-taking tools, according to the needs of geological exploration or engineering work. These samples provide us with the most direct and practical data on underground strata and mineral-bearing characteristics.

[0003] A search revealed that Chinese Patent CN210128882U discloses a core segmentation device, including a device base, on which a first core fixing seat and a second core fixing seat are provided; the first core fixing seat is used to clamp and fix the corresponding segment of the core to be broken, and the second core fixing seat is used to clamp and fix the corresponding segment of the remaining core; the distance between the first core fixing seat and the second core fixing seat is not greater than the allowable segmentation error of the core.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: the core segmentation device shears and misaligns the core, "breaking" it into an irregular shell-like fracture surface, which cannot meet the laboratory requirement of flat ends. Furthermore, the irregular fracture surface makes it difficult to accurately locate the segmentation positions, and the marking fluid easily flows along the fracture gaps, causing blurry and misaligned markings. Additionally, most of the rock powder is directly lost during the breaking process, making it unsuitable as an auxiliary sample for rock layer composition analysis. Therefore, a core segmentation marking device and identification method are proposed to solve the problems mentioned above. Summary of the Invention

Connecting rods are hinged between the left and right sides of the slider and the two transmission blocks, respectively. A connecting block is fixedly connected to the top of the left transmission block, and the first piston cylinder is fixedly connected to the top of the T-shaped slide.

[0016] The advantages of adopting the above-mentioned optional scheme are: by linking the horizontal plate and the guide rod, the lifting of the segmentation device is converted into the movement of the slider; the slider drives the transmission blocks on both sides through the connecting rod, which respectively link the collection structure and the marking structure, realizing the timing coordination of cutting, cleaning and marking, reducing operation steps and improving work coordination.

[0017] Optionally, a limiting plate adapted to the slider is fixedly connected to the outer side of the T-shaped slide block, and an elastic telescopic rod that abuts against the moving block is fixedly connected to the outer side of the transmission block on the right side.

[0018] The advantages of adopting the above-mentioned optional solutions are: limiting the sliding range of the slider by the limiting plate to prevent excessive movement of the slider from causing damage to the components and improving structural safety; and buffering the impact force of the transmission block on the moving block by the elastic telescopic rod to avoid rigid collisions that cause wear to the components, extend the service life of the marking structure, and ensure stable marking action.

[0019] Optionally, the electric push rod is fixedly installed on the top of the horizontal plate and extends to its lower surface. The rotating disk is fixedly connected to the output end of the electric push rod. A retaining spring is provided between the rotating disk and the rotating seat.

A pin extending into the inside of the rotating seat is rotatably connected to the outside of the mounting cylinder. A reciprocating rolling groove adapted to the pin is opened inside the rotating seat.

[0020] The advantages of adopting the above-mentioned optional solutions are: the abutment spring ensures that the rolling ball fits against the outside of the first piston cylinder, improving the vibration effect; the pin and reciprocating rolling groove guide the rotating seat to rotate regularly, causing the rolling ball to vibrate and avoiding dust blockage caused by insufficient local vibration; the overall structure achieves efficient anti-blocking and ensures continuous operation of the collection structure.

[0021] Optionally, the bracket is fixedly connected to the top of the base plate, the support plate is fixedly connected to one side of the top of the base plate, the mounting plate is fixedly connected to the top of the support plate, the mounting seat is fixedly connected to the outside of the mounting plate, an electric telescopic cylinder is fixedly connected to the outside of the mounting seat, a fixed seat is fixedly connected to the output end of the electric telescopic cylinder, a shield is fixedly connected to the bottom of the fixed seat, a drive motor is fixedly installed on the back of the shield, the cutting saw blade is fixedly connected to the output shaft of the drive motor, the telescopic cylinder is hinged to the bottom of the mounting plate, a limit sleeve is rotatably connected to the bottom of the mounting plate, the output end of the telescopic cylinder is rotatably connected to the back of the limit sleeve, a locking device for clamping and limiting the rock core is fixedly installed on the outside of the limit sleeve, the guide rod is fixedly connected to the top of the fixed seat and extends to the upper surface of the mounting seat, and the limit sleeve is fixedly connected to another connecting shaft.

[0022] The advantages of adopting the above-mentioned optional solutions are: the electric telescopic cylinder precisely controls the lifting and lowering of the cutting saw blade, and the drive motor ensures that the saw blade rotates at high speed, thereby improving the cutting quality; the shield prevents the cutting debris from flying, locks the equipment to fix the rock core, avoids cutting deviation, and ensures operational safety and cutting accuracy.

[0023] Another technical problem to be solved by the present invention is to provide a method for identifying rock core segments, comprising the following steps: S1. Cutting and suction linkage: Start the telescopic cylinder of the segmentation device to push the limit sleeve to rotate, so that the locking device clamps the rock core; start the drive motor to drive the cutting saw blade to rotate, and the electric telescopic cylinder pushes the fixed seat to move down to cut; the guide rod synchronously drives the horizontal plate of the synchronous structure to move down, and pushes the first plug rod through the transmission block, so that the first plug plate slides in the first piston cylinder, and the suction tube sucks up the impurities under negative pressure. S2, Vibration Anti-clogging Start: The electric push rod moves down with the horizontal plate, driving the rotating disk to rotate, which in turn drives the ball to vibrate the first piston cylinder through the rotating seat to prevent dust blockage; S3. Reset Linkage After Cutting: After cutting is completed, the electric telescopic cylinder drives the cutting saw blade to move upward, the guide rod pulls the horizontal plate to move upward, and the right transmission block pushes the elastic telescopic rod to squeeze the moving block. S4. Precision marking operation: The wave groove of the moving block drives the roller to slide, so that the second stopper plate squeezes the marking liquid and sprays it from the nozzle to the cutting area through the infusion pipe; S5. Dust discharge and finishing: The vibration mechanism continues to work, helping the dust in the first piston cylinder to be discharged through the discharge pipe and retained in sections, completing one section marking; if multiple sections need to be cut and marked, repeat the above steps, and all structures continue to work together.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, when the segmented device cuts downwards, the guide rod linkage synchronization structure drives the collection structure to generate negative pressure to suck up dust, and the dust enters the first piston cylinder through the conveying pipe; at the same time, the vibration structure moves downwards with the horizontal plate, driving the rolling ball to vibrate the first piston cylinder, realizing the synchronization of cutting and dust suction. The vibration effectively avoids dust clogging the channel, greatly improves the work efficiency, and can also reduce dust diffusion and improve the working environment.

[0025] 2. In this invention, when the cutting is completed, the electric telescopic cylinder drives the cutting saw blade to move upward, the guide rod pulls the horizontal plate to move upward, and the transmission pushes the marking structure moving block, causing the second stopper plate to slide, and the marking liquid is hydraulically injected into the nozzle to be accurately sprayed onto the segment, realizing cutting before marking, effectively avoiding dust contamination of the marking liquid during cutting, ensuring accurate and clear marking, providing accurate identification for subsequent core processing, and improving the quality of operation.

[0026] 3. In this invention, the vibration structure can continue to function regardless of whether the segmentation device is in the downward cutting or upward reset phase. When cutting downward, the vibration prevents the collection structure from being blocked, ensuring smooth dust collection. When the mark is moved upward, the electric push rod moves up with the horizontal plate and can still drive the rotating disk to move downward, causing the ball to vibrate the first piston cylinder. This vibration not only helps the dust collected in the first piston cylinder to be discharged smoothly through the first check valve on the right and the discharge pipe, but also cleans the residual dust on the cylinder wall, reserving cleaning space for the next dust collection, and improving the reusability and operational stability of the collection structure.

[0027] 4. This invention, through the reciprocating sliding of the first stopper plate in the collection structure, independently collects the dust from each cutting operation. After cutting, the dust is discharged with the vibration and reset with the first stopper plate, and is retained in segments, ensuring that the dust samples of each core segment are not mixed. The collected dust can be used as an auxiliary sample to provide data support for the analysis of core composition and structure, making full use of sample resources, improving work efficiency, and meeting the needs of high efficiency, accuracy, and cleanliness in the core processing process. It helps to clarify the occurrence state and distribution law of rare and precious elements in the mining area, summarize their relationship with copper polymetallic ores, and condense the mineralization law of rare and precious elements.

[0030] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail. This application discloses a core segmentation and marking device. Please refer to... Figures 1 to 8 A core segmentation and marking device includes a frame 1 and a segmentation device 2 disposed on the surface of the frame 1. The frame 1 includes a base plate 11, a bracket 12, a support plate 13, and a mounting plate 14. The segmentation device 2 includes a mounting base 21, a cutting saw blade 25, a telescopic cylinder 27, and a guide rod 210. The surface of the base plate 11 is provided with a collection structure 3 for collecting debris and dust generated during core cutting. The surface of the base plate 11 is provided with a marking structure 4 for marking the core segments. The outside of the collection structure 3 is provided with a synchronization structure 5 and a vibration mechanism 6 that are respectively linked to the marking structure 4.

[0031] Specifically, bracket 12 is fixedly connected to the top of base plate 11, support plate 13 is fixedly connected to one side of the top of base plate 11, mounting plate 14 is fixedly connected to the top of support plate 13, and mounting base 21 is fixedly connected to the outside of mounting plate 14.

[0032] It should be noted that an electric telescopic cylinder 22 is fixedly connected to the outside of the mounting base 21. A fixed seat 23 is fixedly connected to the output end of the electric telescopic cylinder 22. A shield 24 is fixedly connected to the bottom of the fixed seat 23. A drive motor 26 is fixedly installed on the back of the shield 24. The cutting saw blade 25 is fixedly connected to the output shaft of the drive motor 26. A telescopic cylinder 27 is hinged to the bottom of the mounting plate 14. A limit sleeve 28 is rotatably connected to the bottom of the mounting plate 14. The output end of the telescopic cylinder 27 is rotatably connected to the back of the limit sleeve 28. A locking device 29 for clamping and limiting the rock core is fixedly installed on the outside of the limit sleeve 28. A guide rod 210 is connected to the top of the fixed seat 23 and extends to the upper surface of the mounting base 21. The electric telescopic cylinder 22 controls the lifting and lowering of the cutting saw blade 25, the drive motor 26 provides cutting power, and the locking device 29 fixes the rock core. The three work together to achieve stable cutting of the rock core. The shield 24 can also prevent rock fragments from flying.

[0033] To achieve real-time collection and segmented retention of cutting dust, the collection structure 3 includes a first piston cylinder 31 disposed outside the mounting plate 14. A conveying pipe 36 is disposed on one side of the outside of the first piston cylinder 31, and the bottom end of the conveying pipe 36 is fixedly connected to a mounting shell 34. A suction pipe 35 is fixedly connected inside the mounting shell 34. By setting the suction pipe 35, dust can be sucked up in real time close to the cutting area. The dust is sent into the first piston cylinder 31 through the conveying pipe 36 and the first check valve 311 on the left side to prevent the dust from spreading.

[0034] The first piston cylinder 31 has a first stopper plate 37 slidably connected inside, and a first stopper rod 38 is fixedly connected to the outside of the first stopper plate 37. A connecting block 39 is fixedly connected to the other end of the first stopper rod 38. A first return spring 310 is fixedly connected between the first stopper rod 38 and the connecting block 39, and the first return spring 310 is wrapped around the outside of the first stopper rod 38. A connecting plate 32 is provided on the outside of the mounting shell 34, and two connecting shafts 33 are fixedly connected to the outside of the connecting plate 32. The mounting shell 34 is fixedly connected to one of the connecting shafts 33. A limiting sleeve 28 is fixedly connected to the other connecting shaft 33. The first stopper plate 37 is automatically reset by the first return spring 310, achieving reset after impurity suction. The first check valve 311 on the right side and the discharge pipe 312 enable directional discharge of dust.

[0035] Specifically, both the left and right sides of the first piston cylinder 31 are fixedly connected to first check valves 311. The left first check valve 311 and the delivery pipe 36 are fixedly connected, and the inside of the right first check valve 311 is fixedly connected to a discharge pipe 312. The dust from each cutting is collected independently by the reciprocating sliding of the first stopper plate 37 through the collection structure 3. After cutting, the dust is discharged by the vibration and reset with the first stopper plate 37, and is retained in segments to ensure that the dust samples of each core segment are not mixed. The collected dust can be used as an auxiliary sample to provide data support for the analysis of core composition and structure, making full use of sample resources and improving work efficiency.

[0036] In order to achieve accurate marking and facilitate subsequent identification after core segmentation, the marking structure 4 includes a liquid storage tank 41 fixedly connected to the outside of the mounting plate 14, a second piston cylinder 42, and a nozzle 410 disposed on one side of the suction pipe 35. A second stopper plate 43 is slidably connected inside the second piston cylinder 42, and a liquid delivery pipe 49 is disposed between the second piston cylinder 42 and the nozzle 410.

[0037] The second stopper plate 43 has a fixed connection at its bottom to a second stopper rod 44 extending to the bottom side of the second piston cylinder 42. A second return spring 46 is fixedly connected between the outer surface of the bottom end of the second stopper rod 44 and the second piston cylinder 42. Two second check valves 47 are fixedly connected to the outside of the second piston cylinder 42. A suction pipe 48 is fixedly connected between the top second check valve 47 and the storage tank 41. A delivery pipe 49 is fixedly connected between the right-side second check valve 47 and the nozzle 410, which is located on the surface of the rock core. By setting the second return spring 46 to assist the second stopper plate 43 in resetting, the marking liquid is automatically drawn from the storage tank 41 through the suction pipe 48 and the top second check valve 47 for replenishment.

[0038] Specifically, a connecting rod 45 is fixedly connected to the bottom end of the second stopper rod 44, a hook block 411 is fixedly connected to the outside of the second piston cylinder 42, a moving block 412 is slidably connected to the outside of the hook block 411, and a sliding groove 413 adapted to the moving block 412 is opened inside the moving block 412. A roller 415 extending into the moving block 412 is rotatably connected to the bottom end of the connecting rod 45, and a wave groove 414 adapted to the moving block 412 is opened inside the moving block 412. The roller 415 and the wave groove 414 are slidably connected, and the second stopper plate 43 is reciprocally slidably connected to the inside of the second piston cylinder 42 through the roller 415 and the wave groove 414. Through the cooperation of the roller 415 and the wave groove 414, the linear motion of the moving block 412 is converted into the reciprocating sliding of the second stopper plate 43, so that the marking liquid is evenly sprayed from the nozzle 410 through the infusion pipe 49 and the second check valve 47 on the right side, ensuring clear marking and providing accurate identification for subsequent core identification.

[0039] To achieve sequential linkage between cutting, waste collection, and marking actions, and to reduce independent operation steps, the synchronization structure 5 includes a horizontal plate 51 fixedly connected to the outside of the guide rod 210 and a T-shaped slide block 52 fixedly connected to the outside of the mounting plate 14. A transmission rod 53 is fixedly connected to the bottom of one side of the horizontal plate 51, and a slider 54 is fixedly connected to the top of the transmission rod 53. Two transmission blocks 55 are horizontally slidably connected to the outside of the T-shaped slide block 52. The slider 54 is vertically slidably connected to the outside of the T-shaped slide block 52. Connecting rods 56 are hinged to the two transmission blocks 55 on the left and right sides of the slider 54, respectively. A connecting block 39 is fixedly connected to the top of the left transmission block 55, and a first piston cylinder 31 is fixedly connected to the top of the T-shaped slide block 52. Through the synchronization structure 5, the raising and lowering of the guide rod 210, i.e., synchronized with the cutting saw blade 25, is transformed into the horizontal sliding of the two transmission blocks 55, realizing the sequential coordination of waste collection structure 3 during cutting and marking structure 4 after cutting, thus reducing operation steps.

[0040] The T-shaped slide 52 has a fixedly connected limiting plate 57 that matches the slider 54 on its outer side, and the right-side transmission block 55 has a fixedly connected elastic telescopic rod 58 that abuts against the moving block 412 on its outer side. By setting the limiting plate 57, the slider 54 is prevented from moving excessively to protect the components, and the elastic telescopic rod 58 buffers the impact of the transmission block 55 on the moving block 412, ensuring a smooth connection between the collecting and marking actions and avoiding rigid collision damage to the components.

[0041] In order to prevent dust blockage in the collection structure 3 and to help retain dust in segments, the vibration mechanism 6 includes an electric push rod 61 and a rotating disk 62 disposed on the outer side of the first piston cylinder 31. The rotating disk 62 is fixedly connected to the outside of the mounting cylinder 63. The mounting cylinder 63 is rotatably connected to a rotating seat 65 extending to its bottom side. The bottom end of the rotating seat 65 is fixedly connected to a ball 66 that is rollingly connected to the outside of the first piston cylinder 31.

[0042] Specifically, the electric push rod 61 is fixedly installed on the top of the horizontal plate 51 and extends to its lower surface. The rotating disk 62 is fixedly connected to the output end of the electric push rod 61. A retaining spring 64 is provided between the rotating disk 62 and the rotating seat 65. The retaining spring 64 is fixedly connected to the top of the rotating seat 65 and is rotatably connected to the inside of the mounting cylinder 63 through the rotating disk 62. A pin 68 extending into the inside of the rotating seat 65 is rotatably connected to the outside of the mounting cylinder 63. A reciprocating rolling groove 67 adapted to the pin 68 is opened inside the rotating seat 65.

[0043] When the segmentation device 2 descends, the ball 66 only relies on itself to contact the outside of the first piston cylinder 31. As the horizontal plate 51 and the guide rod 210 descend synchronously, the ball 66 can slide along the outside of the first piston cylinder 31, avoiding damage caused by the rigid contact between the ball 66 and the first piston cylinder 31 due to the drive of the electric push rod 61, while not affecting the cutting and cleaning operations. When the mark is moved upward, the electric push rod 61 moves upward with the horizontal plate 51. At this time, the electric push rod 61 starts and drives the rotating disk 62 to move downward. The rotating disk 62 drives the mounting cylinder 63 to move synchronously. The rotating seat 65 inside the mounting cylinder 63 rotates under the guidance of the pin 68 and the reciprocating rolling groove 67, and at the same time, the spring 64 provides elasticity to ensure that the ball 66 fits against the outside of the first piston cylinder 31, and finally the ball 66 rolls and vibrates outside the first piston cylinder 31.

[0044] The identification method for segmented marking of rock cores in this embodiment includes the following steps: S1. Cutting and suction linkage: Start the telescopic cylinder 27 of the segmentation device 2 to push the limit sleeve 28 to rotate, so that the locking device 29 clamps the rock core; start the drive motor 26 to drive the cutting saw blade 25 to rotate, and the electric telescopic cylinder 22 pushes the fixed seat 23 to move down to cut; the guide rod 210 synchronously drives the horizontal plate 51 of the synchronous structure 5 to move down, and pushes the first stopper rod 38 through the transmission block 55, so that the first stopper plate 37 slides in the first piston cylinder 31, and the suction pipe 35 sucks up the impurities under negative pressure; S2, Vibration anti-blocking start: The electric push rod 61 moves down with the horizontal plate 51, driving the rotating disk 62 to rotate, which in turn drives the ball 66 to vibrate the first piston cylinder 31 through the rotating seat 65, preventing dust blockage. S3. Reset linkage after cutting: After cutting is completed, the electric telescopic cylinder 22 drives the cutting saw blade 25 to move upward, the guide rod 210 pulls the horizontal plate 51 to move upward, and the right transmission block 55 pushes the elastic telescopic rod 58 to squeeze the moving block 412. S4. Precision marking operation: The wave groove 414 of the moving block 412 drives the roller 415 to slide, so that the second stopper plate 43 squeezes the marking liquid and sprays it from the nozzle 410 to the cutting area through the infusion pipe 49. S5. Dust discharge and finishing: The vibration mechanism 6 continues to work, helping the dust in the first piston cylinder 31 to be discharged through the discharge pipe 312 and retained in sections, completing one section marking; if multiple sections need to be cut and marked, repeat the above steps, and all structures continue to work together.

[0045] Combined with appendix Figures 1 to 8 The working principle of the above embodiments is as follows: The rock core to be segmented is placed on the support 12 of the frame 1. The telescopic cylinder 27 of the segmentation device 2 is activated, and its output end pushes the limiting sleeve 28 to rotate, driving the locking device 29 outside the limiting sleeve 28 to clamp the rock core and prevent the rock core from shifting during cutting. At the same time, the mounting shell 34 is adjusted in position synchronously with the limiting sleeve 28 through the connecting plate 32 and the connecting shaft 33, ensuring that the suction tube 35 of the collection structure 3 is close to the area of ​​the rock core to be cut. When the drive motor 26 of the segmentation device 2 is started, its output shaft drives the cutting saw blade 25 to rotate. At the same time, it controls the extension of the electric telescopic cylinder 22, pushing the fixed seat 23 to move the cutting saw blade 25 downward to cut the rock core. The guide rod 210 at the top of the fixed seat 23 descends synchronously with the fixed seat 23, driving the horizontal plate 51 of the synchronous structure 5 to move downward. The horizontal plate 51 pushes the slider 54 to slide downward on the T-shaped slide seat 52 through the transmission rod 53. The slider 54 pulls the left transmission block 55 to move away from the center of the T-shaped slide seat 52 through the connecting rods 56 on both sides. The left transmission block 55 drives the connecting block 39 and the first plug rod 38 of the collection structure 3 to move synchronously, so that the first plug plate 37 inside the first piston cylinder 31 slides to the right. A negative pressure is formed on the left side of the first piston cylinder 31. The dust generated by cutting is sucked into the first piston cylinder 31 through the left first check valve 311, the conveying pipe 36, and the suction pipe 35, so that cutting and dust collection are carried out simultaneously. After the core cutting is completed, the electric telescopic cylinder 22 is retracted, driving the fixed seat 23, cutting saw blade 25, and guide rod 210 to return to their original positions. The guide rod 210 drives the horizontal plate 51 to move upward. The horizontal plate 51 pulls the slider 54 upward on the T-shaped slide block 52 via the transmission rod 53. The slider 54 pushes the right transmission block 55 towards the marking structure 4 via the connecting rod 56. The elastic telescopic rod 58 outside the right transmission block 55 presses the moving block 412 of the marking structure 4, causing the moving block 412 to slide along the sliding groove 413 of the hook block 411. During sliding, the internal wave groove 414 drives the roller 415 at the bottom of the connecting rod 45 to move up and down. The connecting rod 45 drives the second plug rod 44 and the second plug plate 43 inside the second piston cylinder 42 to slide back and forth. When the second plug plate 43 slides upward, a negative pressure is formed inside the second piston cylinder 42, and the marking liquid is drawn from the storage tank 41 through the top second check valve 47 and the suction pipe 48. When the second plug plate 43 slides downward, the marking liquid is squeezed and sprayed from the nozzle 410 to the core cutting point through the right second check valve 47 and the delivery pipe 49, so as to achieve accurate marking after the core is segmented. When the guide rod 210 moves the horizontal plate 51 upward, i.e., when it is reset and marked after cutting, the electric push rod 61 of the vibration mechanism 6 moves upward synchronously with the horizontal plate 51 and starts. Its output end drives the rotating disk 62 to move downward, and the rotating disk 62 drives the mounting cylinder 63 to move synchronously. The rotating seat 65 inside the mounting cylinder 63 rotates under the guidance of the pin 68 and the reciprocating rolling groove 67. At the same time, the abutment spring 64 at the top of the rotating seat 65 provides elastic force to ensure that the rolling ball 66 at the bottom of the rotating seat 65 always fits against the outside of the first piston cylinder 31, so that the rolling ball 66 rolls and vibrates outside the first piston cylinder 31. The dust collected in the first piston cylinder 31 is loosened by the movement. At the same time, the first stopper plate 37 is reset to the left under the elastic force of the first reset spring 310, and the dust is squeezed out through the first check valve 311 on the right and the discharge pipe 312, realizing the directional discharge and segmented retention of dust. The dust cut each time is discharged with the reset of the first stopper plate 37 along with the vibration, ensuring that the dust samples of each core segment are not mixed, providing auxiliary samples for subsequent core analysis, helping to clarify the occurrence state and distribution law of rare and precious elements in the mining area, summarize their relationship with copper polymetallic minerals, and condense the mineralization law of rare and precious elements.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
