Description

Technical Field

[0001] This invention relates to the technical field of mineral exploration equipment, and more particularly to a geological and mineral exploration sampling device. Background Technology

[0002] In the field of mineral resource exploration, with the deep application of intelligent and automated technologies, mineral geological exploration using high-tech methods such as intelligent drilling equipment has become the mainstream trend. However, in existing technologies, the traditional core sampling process requires a separate operation involving "extracting the core from the sampling tube, cutting the equipment into sections, and manually transferring it to the storage container." This process has the following drawbacks:

[0003] In traditional core sampling operations, after the core sample is extracted through a sampling tube, it needs to be removed from the tube, cut into segments by cutting equipment, and then stored. During this process, the core sample is exposed to the external environment for a long time and is frequently handled. Prolonged contact with oxygen, moisture, dust, and other substances in the air can easily lead to mineral oxidation, contamination, or physical damage. These factors can not only cause changes in the chemical properties and mixing of components of the core sample, but also seriously interfere with subsequent mineral composition analysis, lithology identification, and other testing work, greatly affecting the accuracy of the test results and misleading subsequent resource exploration and geological research.

[0016] Preferably, a silicone liner is fixedly connected to the inner wall of the sample storage tube.

[0017] Compared with related technologies, the geological and mineral exploration sampling equipment provided by the present invention has the following beneficial effects:

[0018] 1. In this invention, after sampling is completed in the sampling unit, the sampling tube is aligned with the storage tube, and then the core sample is cut into segments by the cutting unit. The cut core sample is directly stored in the storage tube, and then the top of the storage tube is sealed with a cap, so that the cut core sample is in an independent closed environment. The whole process reduces the contact time between the core sample and the external environment, greatly reduces the impact of the external environment on the core sample, and thus ensures the accuracy of subsequent test results.

[0019] 2. In this invention, the rotating disk in the rotating switching component is equipped with a circular array of several sample storage tubes, which can realize the continuous storage of multiple samples, greatly improving the storage efficiency of core samples. Furthermore, by storing in segments, each section of core is placed in a sample storage tube, thus preventing cross-contamination between cores. The electric cylinder in the driving component drives the L-shaped rod to move up and down through extension and retraction, causing the driving column to move in the vertical guide groove and the inclined guide groove. Combined with the action of the first guide step and the second guide step, it can accurately drive the switching tube and the rotating disk to rotate in the same direction, realizing the orderly switching of sample storage tubes. Through the setting of the horizontal slide bar and spring in the driving component, the driving column can better adapt to the different depth changes of the vertical guide groove and the inclined guide groove during the movement, keeping the driving column tightly fitted in the vertical guide groove and the inclined guide groove, ensuring the stability and accuracy of the driving process.

[0020] 3. A layer of silicone pad is fixedly connected to the inner wall of the sample storage tube. Due to the good elasticity and cushioning performance of the silicone pad, it can effectively absorb vibration energy, reduce vibration damage to the core sample during storage, and protect the stored core sample.

[0021] 4. In this invention, by providing an inner spiral groove on the inner wall of the sampling tube, the inner spiral groove can guide the rock fragments entering the sampling tube to be discharged upward, thereby reducing the accumulation of rock fragments in the sampling tube, reducing the scraping of the rock core by the rock fragments, and further protecting the rock core sample.

[0022] 5. The rotating wheel in the sealing component moves under the guidance of the inclined guide and horizontal guide of the guide component, driving the lifting slide, hinge rod and rotating rod to automatically open the cover. When the elastic potential energy of the spring plate is released, the cover can automatically reset and close. In addition, the contact surface between the cover and the sample storage tube is equipped with a silicone sealing ring, which enhances the sealing performance, thereby preventing the sample from being affected by the external environment, ensuring the stability and safety of the independent storage of the core sample, and preventing cross-contamination.

[0023] 6. The horizontal column in the cutting unit is fixedly connected to the L-shaped rod of the driving component. The two ends of the horizontal column extend into the oblique elongated hole of the moving frame. When the L-shaped rod moves up and down, it drives the moving frame to slide on the guide slide rod through the horizontal column, so that the electric cutter automatically moves away from or aligns with the sample storage tube to cut the rock core. No additional power is needed to drive the electric cutter to move, which simplifies the structural design.

[0024] 7. The supporting components and sampling components of the sampling unit are designed to work together so that the sampling tube can be adjusted to a vertical position during sampling and to be tilted to correspond with the sample storage tube after sampling, thus meeting the work requirements at different stages.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] Please refer to the following: Figures 1 to 8A geological and mineral exploration sampling device includes a support frame 1. Four casters with locking mechanisms are symmetrically mounted on the bottom of the support frame 1. A sampling unit 2 is mounted on one side of the top of the support frame 1, and a fixed frame 3 is fixedly connected to the other side of the top of the support frame 1. A switching and storage unit 4 is mounted on the fixed frame 3, and a sealing unit 5 is provided on the switching and storage unit 4. A cutting unit 6 is also provided on the fixed frame 3. The switching and storage unit 4 includes a rotating switching component 41 and a driving component 42. The rotating switching component 41 includes a mounting shaft 418, the bottom end of which is fixedly connected to the outer wall of the fixed frame 3. A rotating disk 411 is rotatably connected to the outer side of the mounting shaft 418. A switching tube 412 is fixedly connected to the upper surface of the rotating disk 411, and the top end of the mounting shaft 418 extends into the switching tube 412. A number of sample storage tubes 413 are arranged in a circular array on the rotating disk 411. The sample storage tubes 413 are detachably installed on the rotating disk 411. A number of vertical guide grooves 414 and inclined guide grooves 415 are arranged in a circular array on the outer side of the switching tube 412. The vertical guide grooves 414 and inclined guide grooves 415 are arranged in an alternating circular array. The top of the inclined guide groove 415 is connected to the top of an adjacent vertical guide groove 414, and the bottom of the vertical guide groove 414 is connected to the middle of another adjacent vertical guide groove 414. The top of the vertical guide groove 414 is provided with a second guide step 417, and the bottom of the inclined guide groove 415 is provided with a first guide step 416. The number of vertical guide grooves 414 and inclined guide grooves 415 just form a circle around the outer side of the switching tube 412.

[0042] In the above, the mounting shaft 418 provides stable support and rotation axis for the rotating disk 411 and the switching tube 412, enabling the rotating disk 411 to rotate around the mounting shaft 418. The circumferentially arrayed sample storage tubes 413 can realize the continuous storage of multiple samples, improving sampling efficiency. The connected design of the vertical guide groove 414 and the inclined guide groove 415, together with the limiting effect of the first guide step 416 and the second guide step 417, can ensure that the drive column 423 moves along a specific path, thereby accurately driving the switching tube 412 and the rotating disk 411 to rotate in the same direction, realizing the orderly switching of the sample storage tubes 413. The outer side of the sample storage tubes 413 is affixed with Arabic numerals marked in sequence.

[0043] Furthermore, the drive component 42 includes an electric cylinder 421, which is disposed inside the switching tube 412 and fixedly connected to the top end of the mounting shaft 418. An L-shaped rod 422 is fixedly connected to the telescopic end of the electric cylinder 421. A horizontal slide rod 424 is rotatably connected to the bottom end of the L-shaped rod 422. A drive column 423 is rotatably connected to one end of the horizontal slide rod 424. A fixing block 426 is fixedly connected to the other end of the horizontal slide rod 424. A spring 425 is sleeved on the outside of the horizontal slide rod 424. One end of the spring 425 is fixedly connected to the outer wall of the fixing block 426, and the other end of the spring 425 is fixedly connected to the outer wall of the L-shaped rod 422. The drive column 423 extends into the vertical guide groove 414.

[0044] In the above, the electric cylinder 421 drives the L-shaped rod 422 to move up and down through its telescopic action, thereby causing the drive column 423 to move in the vertical guide groove 414 and the inclined guide groove 415, thus driving the rotation of the switching tube 412. The horizontal slide bar 424 and the spring 425 are designed so that the drive column 423 can better adapt to the different depths of the vertical guide groove 414 and the inclined guide groove 415 during the movement, so that the drive column 423 remains tightly fitted in the vertical guide groove 414 and the inclined guide groove 415.

[0045] Furthermore, a silicone pad 4131 is fixedly connected to the inner wall of the sample storage tube 413. The silicone pad 4131 is a perforated silicone pad.

[0046] Among the above, the silicone pad 4131 has good elasticity and cushioning properties, which can absorb vibration energy and reduce vibration damage to the core sample during storage.

[0047] Example 2

[0048] For further details, please refer to [link / reference]. Figures 1 to 10 Based on Embodiment 1, the sealing unit 5 includes a capping component 51 and a guide component 52. Both the capping component 51 and the guide component 52 are mounted on the rotating switching component 41. The capping component 51 is set in a one-to-one correspondence with the sample storage tube 413.

[0049] As described above, the sealing unit 5 enables the automatic opening and closing of the top opening of the sample storage tube 413. The sealing component 51 corresponds one-to-one with the sample storage tube 413, ensuring that each sample storage tube 413 can be accurately opened and closed before and after storing the sample.

[0050] Furthermore, the sealing component 51 includes a support base 514, which is fixedly connected to the upper side of the corresponding sample storage tube 413. The bottom end of the support base 514 is rotatably connected to a rotating rod 513 via a pin. One end of the rotating rod 513 is fixedly connected to a cover 511. A silicone sealing ring is fixedly connected to the contact surface between the cover 511 and the sample storage tube 413. The other end of the rotating rod 513 is rotatably connected to a hinge rod 515. The bottom end of the hinge rod 515 is rotatably connected to a lifting slide rod 516. The lifting slide rod 516 is slidably connected to the rotating disk 411. The bottom end of the lifting slide rod 516 is rotatably connected to a rotating wheel 517. A spring plate 512 is provided between the rotating rod 513 and the support base 514. One end of the spring plate 512 is fixedly connected to the outer wall of the rotating rod 513, and the other end of the spring plate 512 is fixedly connected to the outer wall of the support base 514.

[0051] As described above, the support base 514 provides a mounting base for the rotating rod 513 and the cover 511. When the rotating wheel 517 rises and falls under the action of the guide component 52, the rotating rod 513 is driven to rotate through the hinge rod 515, thereby realizing the opening and closing of the cover 511. The elastic action of the spring plate 512 enables the cover 511 to automatically reset when the external force is lost, ensuring the sealing of the sample storage tube 413. The silicone sealing ring enhances the sealing between the cover 511 and the sample storage tube 413, preventing the sample from being affected by the external environment.

[0052] Furthermore, the guide component 52 includes a fixed crossbar 521, one end of which is fixedly connected to the outer wall of the mounting shaft 418, and the other end of which is fixedly connected to a guide block 522. The guide block 522 is provided with an inclined guide portion 523 and a horizontal guide portion 524, and the rotating wheel 517 is correspondingly provided with the inclined guide portion 523.

[0053] In the above, the fixed crossbar 521 fixes the guide block 522 on the mounting shaft 418 to keep its position stable. The shape design of the inclined guide part 523 and the horizontal guide part 524 can guide the movement trajectory of the rotating wheel 517. When the sample storage tube 413 rotates, the rotating wheel 517 moves downward along the inclined guide part 523, driving the cover 511 to open. When the rotating wheel 517 reaches the horizontal guide part 524, the cover 511 remains open to facilitate sample placement. When the sample storage tube 413 continues to rotate, the rotating wheel 517 leaves the guide block 522, the spring plate 512 resets, and the cover 511 closes, realizing automatic control of the opening and closing of the cover 511.

[0054] Example 3

[0055] For further details, please refer to [link / reference]. Figures 1 to 13Based on Embodiment 2, the cutting unit 6 includes guide slide rods 65. Two guide slide rods 65 are symmetrically arranged. Both ends of the guide slide rods 65 are fixedly connected to the outer wall of the fixed frame 3. The outer sides of the two guide slide rods 65 are slidably fitted with a movable frame 61. One side of the movable frame 61 is fixedly connected to a mounting shell 63. An electric cutter 64 is fixedly installed on the mounting shell 63. Two oblique elongated holes 62 are symmetrically opened on the other side of the movable frame 61. A horizontal column 66 is fixedly connected to the top of the L-shaped rod 422. Both ends of the horizontal column 66 extend into the two oblique elongated holes 62 respectively.

[0056] In the above description, the guide slide 65 provides guidance for the movement of the moving frame 61, allowing the moving frame 61 to move along the axial direction of the guide slide 65. This enables the electric cutter 64 to accurately align with the core position above the sample storage tube 413 for cutting. The cooperation between the oblique elongated hole 62 and the horizontal column 66 allows the L-shaped rod 422 to move up and down, driving the moving frame 61 to slide on the guide slide 65 via the horizontal column 66. This achieves automatic movement of the electric cutter 64 without the need for an additional power source, simplifying the structural design. It also enables the linkage control of the cutting action and the switching action of the sample storage tube 413, improving the working efficiency and automation level of the equipment.

[0057] Furthermore, the sampling unit 2 includes a support component 21 and a sampling component 22. The support component 21 is mounted on the support frame 1, and the sampling component 22 is mounted on the support component 21.

[0058] In the above, the support component 21 provides mounting support and motion guidance for the sampling component 22.

[0059] Furthermore, the support component 21 includes a guide frame 211. Two inclined positioning grooves 216 and a vertical positioning groove 217 are symmetrically formed on both sides of the guide frame 211. The bottom end of the inclined positioning groove 216 communicates with the top end of the vertical positioning groove 217. A U-shaped guide seat 214 is provided on the upper inner side of the guide frame 211. Two upper guide posts 212 and a lower guide post 218 are symmetrically fixedly connected to both sides of the U-shaped guide seat 214. One end of the lower guide post 218 passes through the vertical positioning groove 217 and is rotatably connected to the inner wall of the U-shaped lifting seat 213. The lower guide post 218 is slidably disposed within the vertical positioning groove 217, and the upper guide post 212 extends into the inclined positioning groove 217. Inside the positioning groove 216, a U-shaped lifting seat 213 is provided on the outer side of the guide frame 211. An upper guide column 212 is longitudinally slidably connected to one side of the U-shaped lifting seat 213, and a vertical threaded rod 219 is longitudinally threaded to the other side of the U-shaped lifting seat 213. A first motor 215 is fixedly installed on the upper side wall of the guide frame 211. The top end of the vertical threaded rod 219 is fixedly connected to the rotating end of the first motor 215, and the bottom end of the vertical threaded rod 219 is rotatably connected to the top of the support frame 1. The bottom end of the upper guide column 212 is fixedly connected to the top of the support frame 1, and the top end of the upper guide column 212 is fixedly connected to the outer wall of the guide frame 211.

[0060] In the above, the first motor 215 drives the vertical threaded rod 219 to rotate, and the U-shaped lifting seat 213 moves up and down through the threaded connection, thereby driving the U-shaped guide seat 214 and the sampling component 22 to rise and fall. The upper guide column 212 slides in the inclined positioning groove 216 and the vertical positioning groove 217, and the lower guide column 218 slides in the vertical positioning groove 217, realizing the angle adjustment of the U-shaped guide seat 214. During sampling, the sampling tube 222 is adjusted to a vertical state. After sampling, the sampling tube 222 is adjusted to an inclined state so that it corresponds to the sample storage tube 413.

[0061] Furthermore, the sampling component 22 includes a second motor 221, which is fixedly mounted on a U-shaped guide seat 214. The rotating end of the second motor 221 passes through the U-shaped guide seat 214 and is fixedly connected to the top end of the sampling tube 222. The bottom end of the sampling tube 222 is provided with a cutting edge 224, and an inner spiral groove 223 is provided on the inner side wall of the sampling tube 222. The top end of the inner spiral groove 223 penetrates the sampling tube 222.

[0062] In the above, the second motor 221 provides rotational power to the sampling tube 222, enabling the sampling tube 222 to drill and sample through the cutting edge 224. The design of the inner spiral groove 223 guides the rock cuttings upward along the spiral groove, reducing the accumulation of rock cuttings in the sampling tube 222 and also reducing the scraping of the rock core by the rock cuttings, protecting the integrity of the rock core sample and improving the sampling quality. The sharp design of the cutting edge 224 helps to improve the drilling efficiency of the sampling tube 222 and make the sampling process smoother. The cutting edge 224 has a stepped design with an outer edge and an inner edge. The outer edge cuts first to reduce the friction between the rock core and the tube wall of the sampling tube 222. The inner edge is used for secondary trimming to ensure that the rock core diameter is consistent, so that the sampled rock core remains in an overall cylindrical shape. The rotation direction of the inner spiral groove 223 matches the rotation direction of the sampling tube 222.

[0063] Furthermore, the first motor 215, the second motor 221, the electric cylinder 421, and the electric cutting machine 64 are all electrically connected to an external control switch via wires. The external control switch is electrically connected to an external power supply, and the first motor 215, the second motor 221, the electric cylinder 421, and the electric cutting machine 64 are controlled to work through the external control switch.

[0064] In the above, by electrically connecting the first motor 215, the second motor 221, the electric cylinder 421, and the electric cutting machine 64 to an external control switch via wires, the operator can conveniently control the working status of each component through the external control switch.

[0065] The working principle of the geological and mineral exploration sampling equipment provided by this invention is as follows:

[0066] In practical use, the geological and mineral exploration sampling equipment of this invention is moved to the location where sampling is required. The first motor 215 is started, causing the rotating end of the first motor 215 to drive the vertical threaded rod 219 to rotate. Through the threaded connection between the vertical threaded rod 219 and the U-shaped lifting seat 213, and the sliding connection between the U-shaped lifting seat 213 and the upper guide column 212, the rotation of the vertical threaded rod 219 drives the U-shaped lifting seat 213 to move downward. The U-shaped lifting seat 213 drives the lower guide column 218, causing the U-shaped guide seat 214 to move downward. The upper guide column 212 gradually enters the vertical positioning groove 217 from the inclined positioning groove 216. During the process of the upper guide column 212 entering the vertical positioning groove 217 from the inclined positioning groove 216, the U-shaped guide seat 214 and the lower guide column 218 rotate, thereby... The sampling component 22 is rotated synchronously until the sampling tube 222 is adjusted from an inclined state to a vertical state. At this time, the upper guide column 212 and the lower guide column 218 are both located in the vertical positioning groove 217. The cutting edge 224 corresponds to the sampling position. Then, the second motor 221 is started, which drives the sampling tube 222 to rotate. At the same time, the first motor 215 drives the vertical threaded rod 219 to rotate, so that the U-shaped lifting seat 213 continues to move downward, thereby causing the sampling tube 222 to move downward. The sampling tube 222 works with the cutting edge 224 to drill. As the sampling tube 222 goes deeper into the ground, the columnar rock core enters the sampling tube 222. During the drilling process of the sampling tube 222, the external water supply equipment is used to cool the sampling tube 222 until the sampling work is completed.

[0067] After sampling is completed, the second motor 221 is turned off, and the first motor 215 is reversed. The first motor 215 drives the vertical threaded rod 219 to rotate, causing the U-shaped lifting seat 213 to move upward. As the U-shaped lifting seat 213 moves upward, it drives the sampling tube 222 to move upward until the upper guide column 212 enters the inclined positioning groove 216 from the vertical positioning groove 217. At this time, the U-shaped guide seat 214 rotates, and the U-shaped guide seat 214 drives the sampling tube 222 to rotate synchronously until the bottom end of the sampling tube 222 is aligned with one of the storage tubes 413. The electric cylinder 421 is then activated, and the telescopic end of the electric cylinder 421 extends upward, driving the L-shaped rod 422 to move upward. The L-shaped rod 422 drives the horizontal column 66 to move upward synchronously. The horizontal column 66 moves upward in the inclined elongated hole 62, thereby pushing the moving frame 61 to slide on the guide slide rod 65. The moving frame 61 drives the mounting shell 63 to move the electric cutter 64 away from the storage tube 413.

[0068] As the L-shaped rod 422 moves upward, it drives the horizontal sliding rod 424, causing the drive column 423 to move upward until the drive column 423 moves from the bottom end of the vertical guide groove 414 to the top end of the vertical guide groove 414. The first guide step 416 and the second guide step 417 act as limiters. When the drive column 423 enters the next vertical guide groove 414 from the inclined guide groove 415, the first guide step 416 prevents the drive column 423 from entering the previous inclined guide groove 415. The second guide step 417 ensures that once the drive column 423 enters the next inclined guide groove 415 from the top end of the vertical guide groove 414, it can only move along the inclined guide groove 415 and will not re-enter the previous vertical guide groove 414. This causes the drive column 423 to drive the switching tube 412 to rotate in the same direction. When the drive column 423 enters the inclined guide groove 415 from the top of the vertical guide groove 414, the distance between the electric cutter 64 and the sample storage tube 413 is at its maximum. Then, the telescopic end of the electric cylinder 421 is retracted, driving the L-shaped rod 422 to move downward, causing the drive column 423 to move downward along the inclined guide groove 415. This causes the switching tube 412 to drive the rotating disk 411 to rotate, and the rotating disk 411 drives the sample storage tube 413 to rotate synchronously, rotating the next sample storage tube 413 one unit. The next sample storage tube 413 without a core sample corresponds exactly to the sampling tube 222. At the same time, the drive column 423 moves downward along the inclined guide groove 415, and the sample storage tube 222 is installed. The capping component 51 on the next sample tube 413 rotates synchronously, causing the rotating wheel 517 to move downward under the guidance of the inclined guide 523 until it enters the horizontal guide 524. As the rotating wheel 517 moves downward along the inclined guide 523, it pulls the lifting slide rod 516 downward. The lifting slide rod 516 pulls the hinge rod 515 to move, and the hinge rod 515 pulls the rotating rod 513 to rotate. The rotating rod 513 drives the cap 511 to rotate, causing the cap 511 to open from the top of the sample tube 413. At this time, the spring plate 512 undergoes elastic deformation. When the rotating wheel 517 is at the horizontal guide 524, the lifting slide rod 516 remains at the current height, thus keeping the cap 511 at the current open position. With the sample tube 222 in the open position, the operator pulls the cylindrical core sample outwards, inserting it into the storage tube 413 at the current position. If the core sample is difficult to remove from the sample tube 222, it can be tapped to make it slide out more easily. Once the core sample is inserted into the storage tube 413, the extension end of the electric cylinder 421 is activated to move downwards. At this time, the drive column 423 moves downwards from the middle of the vertical guide groove 414, the switching tube 412 remains stationary, and the horizontal column 66 moves downwards, causing the moving frame 61 to drive the electric cutter 64 towards the storage tube 413. The electric cutter 64 is then activated, and its cutting blade rotates to cut the core sample.This process can be performed by cooling the cutting blade of the electric cutter 64 using external cooling equipment as needed. After the core sample is cut, the extension end of the electric cylinder 421 is extended in the manner described above, moving the electric cutter 64 away from the sample storage tube 413. When the drive column 423 enters the next inclined guide groove 415 and the switching tube 412 rotates, the previous sample storage tube 413 containing the core sample is displaced from the electric cutter 64. As the switching tube 412 rotates, the current rotating wheel 517 moves away from the horizontal guide part 524, eliminating the resistance of the guide block 522 to the rotating wheel 517. At this time, the elastic potential energy of the spring plate 512 is released, causing the cover 511 to reset and close again on the top of the sample storage tube 413. Thus, the core sample is sealed inside the sample storage tube 413 through the cooperation of the cover 511 and the sample storage tube 413. A silicone liner 4131 is placed on the inner side of the sample storage tube 413 to absorb vibration energy and separate the core sample from the sample storage tube 413. When all sample storage tubes 413 contain core samples, the electric cylinder 421 is driven to disengage all the rotating wheels 517 from the guide blocks 522, so that all the covers 511 close on the sample storage tubes 413.
