Description

Technical Field

[0001] This invention belongs to the field of rock core cutting, and in particular relates to an automated cutting and sampling device and method for geological rock core samples. Background Technology

[0002] Geological cores are cylindrical rock samples obtained from underground through drilling. They contain crucial geological information such as stratigraphic structure, mineral composition, paleontological remains, and fluid inclusions, serving as important evidence for mineral resource exploration, geological scientific research, oil and gas reservoir evaluation, and engineering geological assessment. To conduct subsequent analyses such as elemental dating, isotope analysis, rock mechanics testing, and thin section identification, the original long core is typically split in half, and one half of the sample is then crushed for testing.

[0003] Currently, core cutting mainly relies on a combination of manual operation and semi-automatic mechanical equipment. A typical process involves the operator placing the core on the cutting machine's worktable and hand-holding the device to cut it. This method requires close-range operation throughout the process, posing a high risk of mechanical injury.

[0024] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0025] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0026] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0027] Please see Figure 1 , 4 The present invention provides an automated cutting and sampling device for geological core samples, comprising: a base 1, a core transfer mechanism 2, and a flipping mechanism 3, a translation mechanism 4, a cutting mechanism 5, and a storage mechanism 6 disposed on the base 1.

[0028] like Figure 2-3 As shown, the core transfer mechanism 2 includes a first housing 21, a second housing 22, and multiple fixing components 23. Multiple V-shaped limiting grooves 24 are respectively provided on the opposing inner surfaces of the first housing 21 and the second housing 22. The V-shaped grooves increase the adaptability to different core diameters. The fixing components 23 are used to detachably connect the first housing 21 and the second housing 22, and the opposing V-shaped limiting grooves 24 together form a receiving cavity for clamping and fixing the core. The fixing components 23 can be bolt-fixed structures. Specifically, two lugs (e.g.,...) are provided at intervals on the two side walls of the first housing 21 and the second housing 22. Figure 2 The front and rear sidewalls of the housing have mounting holes on the lugs. After the screw passes through the two mounting holes, it is connected with the nut, thereby connecting the first housing 21 and the second housing 22 together.

[0029] In this embodiment, the first housing 21 and the second housing 22 can be made of plastic to reduce their weight. After the rock core is sampled, it is first cut to a specific length and then placed into the V-shaped limiting groove 24 of the first housing 21. Then, the second housing 22 is placed on top of the first housing 21, and the two are fixed together by the fixing component 23. At this time, the rock core transfer mechanism 2 can be transferred as a whole to facilitate subsequent cutting of the rock core. In this embodiment, when the fixing component 23 fixes the first housing 21 and the second housing 22 together, that is, when the rock core is clamped and fixed, a gap is maintained between the first housing 21 and the second housing 22.

[0030] The flipping mechanism 3 is detachably connected to the first housing 21 and is used to change the core transfer mechanism 2 from a horizontal position to a vertical position. The translation mechanism 4 is detachably connected to the second housing 22, which is in a vertical position. The cutting mechanism 5 includes a drive assembly 51, a cutting assembly 52, and a separating assembly 53. The drive assembly 51 is used to simultaneously drive the cutting assembly 52 and the separating assembly 53 to move up and down. The cutting assembly 52 is located below the separating assembly 53 and is used to cut the core. The separating assembly 53 is used to limit the two sub-cores formed after the core is cut in half within the V-shaped limiting groove 24. The storage mechanism 6 is located below the cutting mechanism 5. The translation mechanism 4 is used to drive the second housing 22 to translate after the cutting is completed, so that the sub-cores in the second housing 22 fall into the storage mechanism 6. The storage mechanism 6 can be a storage box structure with an opening at the top, which is placed below the cutting mechanism 5 to store the sub-cores.

[0031] In this embodiment, when it is necessary to cut the rock core, the entire rock core transfer mechanism 2 is placed onto the flipping mechanism 3, and then the flipping mechanism 3 changes the rock core from a flat state to a vertical state. After the rock core transfer mechanism 2 is in a vertical state, the translation mechanism 4 moves towards the rock core transfer mechanism 2 to connect with the second housing 22.

[0032] The cutting mechanism 5 then drives the cutting component 52 and the separating component 53 downwards as a whole through the drive component 51 until the cutting component 52 passes through the gap between the first housing 21 and the second housing 22 and comes into contact with the rock core. At this time, the cutting component 52 is activated to cut the rock core, and at the same time, the drive component 51 drives the cutting component 52 and the separating component 53 downwards in sync. In this way, the two sub-cores formed by the cut rock core can be separated at the same time as the rock core is cut.

[0033] After the cutting mechanism 5 has finished cutting all the rock cores in the core transfer mechanism 2, the cutting mechanism 5 moves to its lowest position. Then, the translation mechanism 4 moves the second shell 22 away from the first shell 21. At this time, the sub-rock cores in the second shell 22, no longer blocked by the separating component 53, fall downwards under their own weight until they fall into the storage mechanism 6. At this point, the operator can pack the sub-rock cores in the storage mechanism 6 or change the storage box. After packing, the drive component 51 drives the cutting component 52 and the separating component 53 to move upwards as a whole. Thus, the sub-rock cores in the first shell 21 also fall into the storage mechanism 6 under their own weight. The operator can then pack these sub-rock cores and change the storage box, thus completing the rock core cutting and packaging steps.

[0034] The storage of the sub-cores within the first housing 21 can also be achieved by having the driving component 51 lift the separating component 53 and the cutting component 52. At this time, the flipping mechanism 3 gradually moves the first housing 21 from a vertical position to a horizontal position. Thus, while the flipping mechanism 3 rotates the first housing 21, the separating component 53 still acts as a barrier, preventing the sub-cores from falling into the storage mechanism 6 under their own weight. Therefore, the sub-cores remain within the first housing 21. At this point, the second housing 22 can be detached from the translation mechanism 4, then placed on top of the first housing 21, and the first housing 21 and second housing 22 can be connected together using the fixing component 23. This allows the sub-cores within the first housing 21 to be sealed in their original arrangement.

[0035] Therefore, in this embodiment, when cutting the rock core, it is not necessary to remove the rock core from the rock core transfer mechanism 2 to complete the cutting, thereby improving the cutting efficiency; and during the cutting process, no manual operation is required, except that the rock core is packaged manually after the cutting is completed, so as to avoid mechanical injury to the operator.

[0036] Understandably, after the translation mechanism 4 is connected to the second housing 22, and before the cutting mechanism 5 cuts the rock core, the operator can manually remove the fixing component 23 to separate the first housing 21 and the second housing 22. Alternatively, the fixing component 23 can remain in place, in which case the cutting component 52 will cut the fixing component 23 simultaneously with the rock core.

[0037] like Figure 1 , 4 As shown, the drive assembly 51 includes a first motor 511, a lead screw 512, a gantry frame 513, and two first guide members 514. The gantry frame 513 is mounted on the base 1, and each of the two support columns of the gantry frame 513 has a first guide member 514, which can be a guide rail. One end of the lead screw 512 is connected to the first motor 511, and the other end is rotatably connected to the top of the gantry frame 513. The cutting assembly 52 and the separating assembly 53 are connected to the lead screw 512 via nuts, and are also slidably connected to the first guide members 514 via sliders. The first motor 511 drives the lead screw 512 to rotate, thereby driving the cutting assembly 52 and the separating assembly 53 to move up and down simultaneously. There can be two lead screws 512, each corresponding to one first guide member 514. Correspondingly, there can be two first motors 511, i.e., one lead screw 512 corresponds to one first motor 511. The first motor 511 can be a servo motor. In this way, the cutting mechanism 5 and the separating mechanism 8 can move up and down synchronously through the action of two first motors 511 and two lead screws 512.

[0038] The cutting assembly 52 includes a first mounting base 521, a second mounting base 522, a second motor 523, a first mounting wheel 524, a second mounting wheel 525, and a diamond cutting wire 526. The first mounting base 521 and the second mounting base 522 are slidably connected to a first guide member 514 via sliders. The first mounting base 521 is connected to a lead screw 512 via a nut. The second motor 523 and the first mounting wheel 524 are mounted on the first mounting base 521, and the first mounting wheel 524 is connected to the second motor 523. The second motor 523 can be connected to the first mounting wheel 524 via a belt drive structure, or the shaft of the first mounting wheel 524 can be rotatably connected to the first mounting base 521 via a bearing and coaxially arranged with the output shaft of the second motor 523. This embodiment does not limit this. The second mounting wheel 525 is rotatably mounted on the second mounting base 522 via a bearing; the diamond cutting wire 526 is a ring-shaped steel wire with diamond abrasive coated on its surface, which is sleeved on the first mounting wheel 524 and the second mounting wheel 525.

[0039] like Figure 1 , 5 As shown, the cutting mechanism 5 also includes a tensioning assembly 54, which is mounted on the second mounting base 522. The tensioning assembly 54 drives the second mounting wheel 525 to move closer to or further away from the first mounting wheel 524, ensuring that the second motor 523 can drive the diamond cutting wire 526 to cut the rock core. Specifically, the tensioning assembly 54 includes an adjusting seat 541, an adjusting column 542, and a second guide member 543. The second guide member 543 is mounted on the second mounting base 522. The adjusting seat 541 is slidably connected to the second guide member 543. The shaft of the second mounting wheel 525 is rotatably connected to the adjusting seat 541. The adjusting column 542 is threadedly connected to the adjusting seat 541, and one end of the adjusting column 542 abuts against the side wall of the second mounting base 522 away from the first mounting wheel 524.

[0040] Two second guide members 543 can be provided, each located on one of the opposite sidewalls of the second mounting base 522. The second mounting base 522 may have a waist-shaped hole. The adjusting base 541 may have a U-shaped structure, with its two inner sidewalls slidably connected to the second guide members 543. The second guide members 543 may be slide rails, with the two inner sidewalls of the adjusting base 541 slidably connected to the second guide members 543 via sliders. Through holes may be provided on the two inner sidewalls of the adjusting base 541, and the shaft of the second mounting wheel 525 may be rotatably connected to the two through holes via bearings. Threads may be provided on the outer surface of the adjusting column 542, and a threaded hole may be provided at the bottom of the groove of the adjusting base 541. The adjusting column 542 is rotatably disposed within the threaded hole, with one end extending into the groove of the adjusting base 541 and abutting against the sidewall of the second mounting base 522 away from the first mounting wheel 524. By rotating the adjusting column 542, the adjusting seat 541 can be moved closer to or further away from the first mounting wheel 524, thereby driving the second mounting wheel 525 to move and achieve tension adjustment.

[0041] like Figure 1 , 4 As shown, the partition assembly 53 includes a partition plate 531 and two third mounting seats 532; the two third mounting seats 532 are slidably connected to a first guide member 514 via sliders; at least one third mounting seat 532 is also connected to a lead screw 512 via a nut; when there are two lead screws 512, each third mounting seat 532 is connected to a lead screw 512 via a nut. The partition plate 531 is connected to the two third mounting seats 532; multiple guide grooves 5311 are spaced apart on the side wall of the partition plate 531 facing the second housing 22, and the extending direction of the guide grooves 5311 is the same as the extending direction of the first guide member 514, which is used to reduce the contact area between the partition plate 531 and the sub-core inside the second housing 22. Of course, multiple guide grooves 5311 can also be spaced apart on the side wall of the partition plate 531 facing the first housing 21, thereby also reducing the contact area between the partition plate 531 and the sub-core inside the first housing 21.

[0042] like Figure 1 , 4As shown, the automated cutting and sampling device for geological core samples in this embodiment further includes a spraying mechanism 7. The spraying mechanism 7 includes a coolant tank 71, a pump 72, and multiple nozzles 73. The coolant tank 71 is provided with a coolant inlet located below the cutting mechanism 5. The multiple nozzles 73 are located above the core transfer mechanism 2 in a vertical position, and each guide groove 5311 is provided with at least one nozzle 73. The pump 72 is connected to the coolant tank 71 and the nozzles 73, and is used to transport the coolant in the coolant tank 71 to the nozzles 73, and spray it through the nozzles 73 to the interval between the first housing 21 and the second housing 22 to control the temperature of the contact portion between the diamond cutting wire 526 and the core. The coolant can be water or other liquids that can be used for cooling, and this embodiment does not limit this.

[0043] like Figure 1 , 4 As shown in Figures 6-7, in this embodiment, the spraying mechanism 7 and the receiving mechanism 6 are both located below the cutting mechanism 5, in order to allow the coolant to flow back into the coolant tank 71 or to allow the sub-cores to fall into the receiving mechanism 6. The automated cutting and sampling device for geological core samples provided in this embodiment also includes a separating mechanism 8, which is spaced apart from the spraying mechanism 7. The separating mechanism 8 includes a guide plate 81, which is rotatably mounted on the base 1. It has a first state and a second state. In the first state, the guide plate 81 guides the used coolant through the coolant inlet into the coolant tank 71; in the second state, the guide plate 81 guides the cut sub-cores to slide into the receiving mechanism 6. The first state corresponds to the state when the cutting mechanism 5 cuts the core, and the second state corresponds to the state when the cutting mechanism 5 has completed cutting all the cores in the core transfer mechanism 2.

[0044] Specifically, the separating mechanism 8 also includes a gear 82 and a rack 83; the guide plate 81 is rotatably mounted on the base 1 via a shaft and bearings, and the gear 82 is mounted on the shaft of the guide plate 81; one end of the rack 83 is connected to the separating plate 531, which meshes with the gear 82 to drive the guide plate 81 to rotate. During the process of the drive assembly 51 driving the cutting assembly 52 and the separating assembly 53 to move downward, the cutting assembly 52 first cuts the rock core, and then after the cutting is completed, the drive assembly 51 continues to drive the cutting mechanism 5 and the separating assembly 53 to move downward. During this movement, the rack 83 and the gear 82 mesh, thereby enabling the drive assembly 51 to drive the separating plate 531 to rotate, so that the guide plate abuts against the separating plate 531, even if the guide plate is in the second state, so as to guide the cut sub-rock core into the receiving mechanism 6. At this time, the diamond cutting wire 526 of the cutting mechanism 5 is located below the guide plate. The falling sub-core will not come into contact with the diamond cutting wire 526, thus effectively preventing damage to the diamond cutting wire 526 from the sub-core. It can be understood that the sub-core is stored in the first housing 21 by the drive assembly 51 raising the separating assembly 53 and the cutting assembly 52. ​​At this time, the flipping mechanism 3 gradually changes the first housing 21 from a vertical state to a horizontal state, meaning the sub-core remains inside the first housing 21 for safekeeping.

[0045] like Figure 1 , 4 As shown in Figures 6 and 7, the flipping mechanism 3 includes a third motor 31, a gear transmission assembly 32, and a first housing fixing seat 33. The rotating shaft of the first housing fixing seat 33 can be rotatably connected to the base 1 via bearings. The first housing fixing seat 33 is provided with a first limiting groove 331 for limiting the first housing 21. The third motor 31 is mounted on the base 1 and drives the first housing fixing seat 33 to rotate via the gear transmission assembly 32. The gear transmission assembly 32 is a commonly used transmission form in related technologies and will not be described in detail in this embodiment.

[0046] The translation mechanism 4 includes a telescopic drive component 41, a third guide component 42, and a second housing fixing seat 43. The telescopic drive component 41 and the third guide component 42 are mounted on the base 1. The telescopic drive component 41 can be a telescopic drive element such as a cylinder or an electric cylinder, and the third guide component 42 can be a guide rail. The second housing fixing seat 43 is connected to the output end of the telescopic drive component 41 and is slidably connected to the third guide component 42 via a slider. The second housing fixing seat 43 is provided with a second limiting groove 431 for accommodating the second housing 22.

[0047] In this embodiment, after the third motor 31 drives the first housing fixing seat 33 to rotate through the gear transmission assembly 32, the core transfer mechanism 2 placed in the first limiting groove 331 changes from a flat state to a vertical state. Then, the telescopic drive member 41 drives the second housing fixing seat 43 to move closer to the core, thereby limiting the second housing 22 in the second limiting groove 431. At this time, the core transfer mechanism 2 can be fixed so that the cutting assembly 52 can cut the core. It is understood that the size of the first limiting groove 331 is adapted to the size of the first housing 21, and the size of the second limiting groove 431 is adapted to the size of the second housing 22. The adaptation here means that the size of the first limiting groove 331 can be slightly larger than the size of the first housing 21, and the size of the second limiting groove 431 can be slightly larger than the size of the second housing 22, so as to ensure that the transfer mechanism can be placed in the first limiting groove 331 and the second limiting groove 431, and that the first housing 21 cannot be removed from the first limiting groove 331 when it is not subjected to a force perpendicular to the bottom of the first limiting groove 331; and the second housing 22 cannot be removed from the second limiting groove 431 when it is not subjected to a force perpendicular to the bottom of the second limiting groove 431.

[0048] On the other hand, the present invention also provides an automated cutting and sampling method for geological core samples, which includes the above-mentioned automated cutting and sampling device for geological core samples, and further includes the following steps: Sampling steps: The area to be sampled is sampled using a core sampling device. After sampling, the cores are placed into the core transfer mechanism 2 in sequence.

[0049] In this step, core sampling equipment such as geological drilling rigs can be used to drill and collect core samples in the area where sampling is required. The obtained columnar core samples need to be initially cleaned and numbered, and their original depth and orientation information is recorded. Subsequently, according to the sampling plan and numbering order, the operators place the core samples one by one in an orderly manner into the first housing 21 of the core transfer mechanism 2, and then cover the first housing 21 with the second housing 22, and connect the first housing 21 and the second housing 22 together using the fixing component 23.

[0050] Fixing steps: Place the core transfer mechanism 2 on the flipping mechanism 3, use the flipping mechanism 3 to keep the core transfer mechanism 2 in a vertical position, and connect the translation mechanism 4 to the second housing 22.

[0051] In this step, the first housing 21 of the core transfer mechanism 2 is placed into the first limiting groove 331 of the flipping mechanism 3, and then the flipping mechanism 3 is activated to change the core transfer mechanism 2 from a horizontal position to a vertical position. Then the translation mechanism 4 is activated to move the translation mechanism 4 towards the first housing 21 so that the second housing 22 of the core transfer mechanism 2 is accommodated in the second limiting groove 431.

[0052] Cutting steps: The core is cut using the cutting component 52, and the cutting component 52 and the separating component 53 are moved downward synchronously by the driving component 51 to complete the cutting of the core.

[0053] In this step, the drive assembly 51 first moves the cutting assembly 52 and the separating assembly 53 downwards from the gap between the first housing 21 and the second housing 22 until the diamond cutting line 526 of the cutting assembly 52 contacts the rock core. Then, the cutting assembly 52 is activated to cut the rock core, and the drive assembly 51 simultaneously moves the cutting assembly 52 and the separating assembly 53 downwards, so that the cutting assembly 52 can cut all the rock cores in the rock core transfer mechanism 2, and the separating assembly 53 can separate the half-cut sub-rock cores.

[0054] Storage steps: Use the translation mechanism 4 to move the second shell 22 away from the first shell 21, so that the sub-core inside the second shell 22 falls into the storage mechanism 6 by its own weight.

[0055] In this step, the translation mechanism 4 moves the second shell 22 away from the first shell 21. At this time, the sub-cores inside the second shell 22, no longer blocked by the separating component 53, fall downwards under their own weight until they fall into the storage mechanism 6. The operator can then pack the sub-cores in the storage mechanism 6 or replace the storage box. After packing, the drive component 51 drives the cutting component 52 and the separating component 53 upwards as a whole. Thus, the sub-cores inside the first shell 21 also fall into the storage mechanism 6 under their own weight. The operator then packs these sub-cores and replaces the storage box, thus completing the core cutting and packaging steps.

[0056] The storage of the sub-cores within the first housing 21 can also be achieved by having the driving component 51 lift the separating component 53 and the cutting component 52. At this time, the flipping mechanism 3 gradually moves the first housing 21 from a vertical position to a horizontal position. Thus, while the flipping mechanism 3 rotates the first housing 21, the separating component 53 still acts as a barrier, preventing the sub-cores from falling into the storage mechanism 6 under their own weight. Therefore, the sub-cores remain within the first housing 21. At this point, the second housing 22 can be detached from the translation mechanism 4, then placed on top of the first housing 21, and the first housing 21 and second housing 22 can be connected together using the fixing component 23. This allows the sub-cores within the first housing 21 to be sealed in their original arrangement.

[0057] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
