Description

Technical Field

[0001] This invention relates to the field of geological and mineral exploration technology, and more specifically to a geological and mineral exploration system. Background Technology

[0002] As is well known, geological and mineral exploration is an applied geological work that uses geological theory as a guide and comprehensively utilizes geological mapping, geophysical exploration, geochemical exploration, or drilling to ascertain the quality, quantity, and development prospects of mineral resources in the shortest possible time and with the least investment. To facilitate geological and mineral exploration operations, we propose a geological and mineral exploration system.

[0003] A search revealed that Chinese patent application number CN202210270812.2 discloses a geological and mineral exploration system. The system generally includes a base with two supports fixedly mounted longitudinally on its top. A top shell is fixedly mounted on the top of the two supports. A lifting assembly is slidably mounted on the outside of the two supports. A push cylinder is fixedly mounted inside the top shell. One end of the output shaft of the push cylinder is fixedly connected to the top surface of the lifting assembly via a telescopic shaft. A top groove is provided on the top surface of the top shell, and a handle is provided inside the top groove. A connecting rod is fixedly mounted on the bottom surface of the top shell, and a suction piston is fixedly mounted at the bottom end of the connecting rod. During use, by incorporating a magnetic drill rod mechanism and an adjustment assembly, the system abandons traditional sampling methods, effectively improving the sampling success rate and stability. Furthermore, during retrieval, samples from other depths are not mixed into the sample chamber, thus effectively improving the accuracy of the final exploration results.

[0024] It should be further explained that an auxiliary rotating frame 30 is rotatably connected to the bottom end of the guide vertical cylinder 2. The drilling motor 12 is used to drive the auxiliary rotating frame 30 to rotate. The exploration drill pipe 3 passes through the guide vertical cylinder 2. A limiting rotation plane 31 is provided in both the guide vertical cylinder 2 and the multiple rotating sleeves 27. A strip plane 32 matching the limiting rotation plane 31 is provided in the exploration drill pipe 3, the connecting tailpipe 19, and the multiple extension pipes 16. Multiple block planes 33 are provided in the exploration drill pipe 3, the connecting tailpipe 19, and the multiple extension pipes 16. A side opening is provided in both the auxiliary rotating frame 30 and the multiple rotating sleeves 27. A limiting block 34 is slidably connected in each of the multiple side openings. A mounting shell 35 is fixedly connected in each of the multiple side openings. A pop-out spring 36 is fixedly connected in each of the multiple mounting shells 35. 6 is fixedly connected to multiple limiting blocks 34 respectively. Electromagnets 37 are installed inside multiple mounting shells 35. The multiple limiting blocks 34 are made of a material that can be magnetically attracted by the electromagnets 37. A quick-connect pipe 20 is rotatably connected to an intermediate ring 38, which is slidably connected to the connecting tailpipe 19. A contact limiting ring 39 is fixedly connected to the outside of the connecting tailpipe 19. The bottom end of the quick-connect pipe 20 is provided with a limiting tooth surface 40 that matches the contact limiting ring 39. The top end of the connecting tailpipe 19 is provided with a limiting protrusion that matches the intermediate ring 38. Two lifting extension plates 45 are fixedly connected inside the vehicle frame 41. A transverse limiting frame 46 is fixedly connected between the two lifting extension plates 45. The transverse limiting frame 46 is used for auxiliary support and limiting of the storage cylinder 13. The storage cylinder 13 is fixedly connected to the outside. A structural protective frame 47 is connected to the mounting shaft frame 1. The structural protective frame 47 is equipped with a contact pressing block 48 that matches the transverse limiting frame 46. The exploration drill pipe 3, the connecting tailpipe 19, and multiple extension pipes 16 all adopt a double-layer structure of inner and outer casing. The inner casing contains an inner pipeline that connects to the interior of the lifting inner rod 5. By injecting pressurized liquid into this inner pipeline, the drill bit frame 6 and drill bit ring frame 7 can maintain a uniform height, meaning the bottom drilling surfaces of the drill bit frame 6 and drill bit ring frame 7 remain flush. Conversely, when pressurized liquid is extracted from the corresponding inner pipeline of the inner casing, causing the lifting inner rod 5 to enter a negative pressure state, the lifting inner rod 5 will rise relative to the drill bit frame 4, thus raising the drill bit frame... 6. Relative to the drill bit holder 7, the drill bit holder 6 moves and rises. In this state, when the drill bit holder 6 and drill bit holder 7 perform drilling operations again, the drill bit holder 7 will form a ring-shaped breaking operation relative to the drilling point, making the area corresponding to the drilling point and the drill bit holder 6 form an independent columnar structure. The height of the lifting inner rod 5 is controlled. When the lifting inner rod 5 rises to a position that matches the rotating frame 8 and continues to rise, it will push the rotating frame 8 to rotate, thereby causing the side cutting head 9 to rotate and extend, cutting off the drilled columnar structure and realizing the extraction of the columnar structure sample. There is another pipeline between the inner and outer casings, which is defined as the outer pipeline. This outer pipeline is connected to the hole at the bottom of the drill bit holder 4. Liquid is pumped into this outer pipeline and can be discharged through the hole.The drill bit holder 6 and drill bit ring holder 7 are intended to provide lubrication and cooling for drilling operations.

[0025] The drilling motor, first servo motor, electric lifting rod, second servo motor, electromagnet, and electric adjusting rod in this embodiment are all conventional devices known to those skilled in the art and available on the market. In this invention, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0026] In summary, the working principle of this geological and mineral exploration system is as follows: First, the power supply and central control unit are installed. A wireless controller is also installed on the central control unit to facilitate the operation and control of the system via the central control unit. Next, the system is debugged and adapted to the site to ensure coordinated operation of all components, laying the foundation for subsequent drilling operations. Two independent powered tracks 42 move the entire exploration system to the target exploration area. Based on the geological conditions of the exploration point, the equipment attitude is adjusted to ensure the stable movement of the chassis 41, providing stable support for drilling operations. Then, the electric adjusting rod 43 is activated. The electric adjusting rod 43, through the transmission rod 44, drives the mounting shaft 1 to rotate relative to the chassis 41, adjusting the guide cylinder 2 from a horizontal, stowed state to a vertical state, ensuring the guide cylinder 2 is vertically aligned with the target drilling point. Then, the electric adjusting rod 43 is controlled to enter a parking state, maintaining the vertical attitude of the drill bit frame 4. Then, through… The quick-connect fitting 20 connects the internal pipeline to the external hydraulic pump. Through the operation of the internal hydraulic pump, the supply and discharge of liquid in the internal pipeline can be controlled. It also connects to the external pipeline and installs an external hydraulic pump, which pumps liquid into the external pipeline to provide coolant and lubricant to the drill bit holder 6 and drill bit ring holder 7. During formal drilling operations, the drill bit motor 12 is started first, driving the auxiliary rotating frame 30 to rotate. Because the rotation-limiting plane 31 within the auxiliary rotating frame 30 matches the strip plane 32 of the exploration drill pipe 3... The auxiliary rotating frame 30 rotates, causing the exploration drill pipe 3 to rotate synchronously. At the same time, the electric lifting rod 18 is activated. The electric lifting rod 18 drives the quick-connect pipe 20 and the connecting tail pipe 19 to move upward through the extended mounting frame 21, so that the multiple extension pipes 16 have sufficient rotation adjustment space. The first servo motor 15 is activated, and the first servo motor 15 drives the storage rack 14 to rotate, rotating one of the extension pipes 16 in the storage rack 14 to be directly below the insertion port of the mounting plate 17, so that the extension pipe 16 is aligned with the connecting tail pipe 19 on the upper side.

[0027] Furthermore, the second servo motor 26 is activated. The second servo motor 26 drives multiple driven gears 29 to rotate synchronously via the drive gear 28, thereby rotating the rotating sleeve 27. This achieves rotational adjustment of the extension tube 16, aligning the strip plane 32 on the connecting tail tube 19 with the strip plane 32 on the extension tube 16. Then, the electric lifting rod 18 controls the connecting tail tube 19 to descend closer to the extension tube 16 directly below it. Once the extension tube 16 and the connecting tail tube 19 are in contact and pressed together, the second servo motor 26 is activated, causing the extension tube 16 to rotate. Since the connecting tail tube 19 is positioned relative to the extension tube 16 below it... After the connection is tightened, the reaction force between the extension tube 16 and the connecting tail tube 19 causes the contact limiting ring 39 to move upward relative to the limiting tooth surface 40 until they come into contact. Once the contact limiting ring 39 and the limiting tooth surface 40 are in contact, the connecting tail tube 19 is restricted from rotating. Then, the second servo motor 26 is started again, and the extension tube 16 is rotated by the second servo motor 26. This allows the inner threaded bushing 24 and the outer threaded bushing 25 at the top of the extension tube 16 to form threaded connections with the inner threaded sleeve 22 and the outer threaded sleeve 23 on the lower side of the connecting tail tube 19, respectively. This achieves threaded locking between the connecting tail tube 19 and the extension tube 16. Subsequently, the control... When the electromagnet 37 inside the rotating sleeve 27 corresponding to the extension tube 16 is energized, the electromagnet 37 attracts the limiting block 34, causing the limiting block 34 to disengage from the block plane 33 of the extension tube 16, thus releasing the vertical restriction on the extension tube 16. The electric lifting rod 18 continues to drive the connecting tail pipe 19 and the extension tube 16 to move downwards, pushing the bottom end of the extension tube 16 to align with the top end of the exploration drill pipe 3. By controlling the operating status of the second servo motor 26 and the drilling motor 12, the vertical alignment between the exploration drill pipe 3 and the extension tube 16 above it is achieved. Then, by continuing to operate the electric lifting rod 18, the threaded locking operation between the extension tube 16 and the exploration drill pipe 3 is completed. The extension pipe 16 is connected to the exploration drill pipe 3. Then, the electric lifting rod 18 drives the connecting tailpipe 19 to move downward, providing downward pressure to the exploration drill pipe 3. This pushes the drill bit frame 6 and drill bit ring frame 7 to rotate and drill the target rock layer. When the single drilling reaches the maximum depth of the current exploration drill pipe 3, the downward movement of the drilling motor 12 and the electric lifting rod 18 is stopped. The above steps are repeated. Multiple extension pipes 16 can be connected in sequence according to the drilling depth requirements to achieve deep drilling. Before the next extension pipe 16 is threaded in, the connecting tailpipe 19 should be raised and reset by the operation of the electric lifting rod 18. Then, the above steps are repeated to achieve the connection of the next extension pipe 16.

[0028] During drilling, liquid is pumped into the hole at the bottom of the drill bit holder 4 through the external pipeline to provide lubrication and cooling for the drill bit disc holder 6 and drill bit ring holder 7, reducing frictional wear between the rock formation and the drill bit, and removing drilling cuttings to prevent their accumulation from affecting drilling efficiency. The cooperation between the rotation limiting plane 31 and the strip plane 32 prevents slippage of the exploration drill pipe 3, extension pipe 16, and connecting tailpipe 19 during rotation, ensuring stable transmission of drilling power. Once the target depth is reached, the columnar sampling process is initiated. By adjusting the state of the lifting inner rod 5 in conjunction with the action of the side-cutting head 9, columnar samples are extracted to ensure representativeness. During the extraction operation, drilling power is first stopped. The rotation of the machine 12 maintains the fixed state of the exploration drill pipe 3, extension pipe 16, and connecting tailpipe 19. By extracting pressurized liquid from the inner pipeline, a negative pressure is created inside the lifting inner rod 5, causing the lifting inner rod 5 to rise relative to the drill bit frame 4, which in turn raises the drill bit disc frame 6 relative to the drill bit ring frame 7. At this time, the drill bit ring frame 7 remains stationary. The drilling motor 12 is restarted, and the drill bit ring frame 7 performs annular fracturing operations on the current drilling point, forming an independent columnar rock stratum structure at the center of the drilling point. Then, the pressurized liquid in the pipeline continues to be extracted, causing the lifting inner rod 5 to continue to rise. When the lifting inner rod 5 rises to a position that matches the rotating mounting frame 8, the pushing ring surface 11 on the lifting inner rod 5 pushes the two rotating mounting frames 8. Overcoming the elastic force of the spring 10, the side-cutting head 9 is driven to extend out of the drill bit holder 4. The side-cutting head 9 rotates synchronously with the drill bit holder 4 to cut the already formed columnar rock structure, completing the separation of the columnar sample. After the cutting is completed, the drilling motor 12 is stopped, and the electric lifting rod 18 is started, which drives the connecting tailpipe 19, extension pipe 16 and exploration drill pipe 3 to move upward, lifting the drill bit holder 4 and the columnar sample inside to the ground. Then, by reversing the operation, the lifting inner rod 5 is released, so that the side-cutting head 9 is reset under the action of the spring 10, and the columnar sample is taken out, completing the sampling operation. When the electromagnet 37 is energized, the limiting block 34 is attracted by the magnetic force of the electromagnet 37 and overcomes the ejection spring. The elastic drive of 36 causes the limiting block 34 to approach the mounting shell 35 for storage. At this time, the limiting block 34 is separated from the block plane 33 to ensure that the height of the structure formed by the sequential connection of the exploration drill pipe 3, extension pipe 16 and connecting tailpipe 19 can be adjusted when the electric lifting rod 18 is in operation. During the height adjustment process, attention should be paid to the compatibility of the block plane 33 and the limiting block 34 in terms of height to ensure that the limiting block 34 can be smoothly inserted into the block plane 33 after the electromagnet 37 is de-energized, forming a height limit of the structure formed by the sequential connection of the exploration drill pipe 3, extension pipe 16 and connecting tailpipe 19, which facilitates the separation and connection operations between the exploration drill pipe 3, extension pipe 16 and connecting tailpipe 19.
