Description

Technical Field

[0001] This application belongs to the field of rare earth mineral drilling and sampling technology, specifically relating to a drilling and sampling device and sampling method for geological exploration of ion-adsorption rare earth minerals. Background Technology

[0002] Rare earth elements, due to their unique physical and chemical properties, play an irreplaceable role in modern industry and are widely used in high-tech fields such as electronics, aerospace, and new energy. Rare earth elements are widely and unevenly distributed in the Earth's crust. Ion-adsorption rare earth deposits, as an important type of rare earth resource, are rich in heavy rare earth elements such as dysprosium (Dy), terbium (Tb), and europium (Eu). These elements have key application value in high-tech fields and are difficult to replace with other elements. Therefore, the exploration of ion-adsorption rare earth deposits is of paramount importance for the rational development and utilization of rare earth resources.

[0003] Ion-adsorption rare earth minerals are typically found in the weathering crust of granite or volcanic rocks, exhibiting a loose, porous, clay-like structure and primarily composed of clay minerals. Rare earth elements are adsorbed onto the surface of clay particles in an ionic state, rather than existing as solid minerals. This unique occurrence makes rare earth elements easier to extract during weathering, but also presents unique challenges for exploration and sampling.

[0004] During exploration, continuous, uncontaminated sampling at different depths is a crucial step in assessing ore grade and distribution. However, existing technologies have significant shortcomings in the sampling process. Traditional methods typically involve multiple samplings using a fixed sampling container. After the container repeatedly contacts different locations of the ore body, residual rare earth elements can contaminate subsequent samples, failing to accurately reflect the original composition of the ore body at each depth. Furthermore, traditional sampling methods, such as manual sampling with a Luoyang shovel, are not only inefficient and costly but also result in short sampling lengths, making them unsuitable for deep exploration and severely impacting sampling efficiency and data accuracy.

[0005] Therefore, how to achieve independent sampling at different depths, effectively avoid cross-contamination, and ensure the accuracy and reliability of exploration data has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] Based on the above analysis, the present invention aims to provide a drilling and sampling device for geological exploration of ion-adsorption rare earth minerals, in order to solve the problem of cross-contamination of samples in the existing rare earth mineral sampling technology.

A magnet is provided on the side of the top wall of the sampling frame and the top surface of the sampling container to lock the sampling container inside the sampling frame. There is also a gap between the top of the sampling container and the sampling frame to form a first insertion space. The other end of the sampling container includes a sealing member. The sealing member is recessed, so that the other end of the sampling container has a second insertion space.

[0026] The insert plate can be inserted into the first insertion space, and the insert can be inserted into the second insertion space.

[0027] Furthermore, the sampling end of the sampling frame is connected to a U-shaped protrusion, the cross-sectional shape of which is the same as that of the sampling frame. The protrusion has three vertical inner walls with grooves forming a U-shaped groove. A slider is installed in the groove on one vertical inner wall.

[0044] After sampling is completed, the sampling drive device reverses its direction, causing the sampling frame to exit from the sampling hole wall and into the loading box.

[0045] The loading and unloading mechanism restarts, removing the sampled container from the sampling frame and moving it to the storage mechanism for storage.

[0046] Furthermore, once all sampling work is completed, the fixing mechanism is released from the sampling hole wall, and the loading box is hoisted out of the sampling hole using ropes, thus completing the entire drilling and sampling process.

[0047] Compared with the prior art, the drilling and sampling equipment and method for geological exploration of ion-adsorption rare earth minerals provided by the present invention can achieve at least one of the following beneficial effects:

[0048] 1. Detachable sampling containers are used, with each container used to collect samples from only one location. After each sampling, the sampling container is removed from the sampling frame and stored separately via a loading and unloading mechanism, before a new container is used for the next sampling. This method fundamentally avoids cross-contamination between samples from different locations, ensuring that each sample accurately represents the original composition of the ore body at the corresponding depth. This improves the accuracy and reliability of rare earth resource exploration data, thereby increasing the efficiency and precision of rare earth resource exploration and providing crucial technical support for the sustainable development of rare earth resources.

[0049] 2.

[0074] A specific embodiment of the present invention, such as Figures 1 to 7 As shown, a drilling and sampling device for geological exploration of ion-adsorption rare earth minerals is disclosed, used for sampling in sampling holes. The device includes:

[0075] The loading container 10 is hoisted and moved by ropes, which facilitates flexible transfer between different sampling locations.

[0076] The fixing mechanism 20 is installed inside the loading box 10 and is configured to extend from inside the loading box 10 and be fixed to the wall of the sampling hole when the loading box 10 reaches the sampling position inside the sampling hole, so as to ensure the stability of the sampling process.

[0077] The sampling frame 30 is set inside the loading box 10. The side wall inside the loading box 10 is provided with a sampling channel 11. The position of the sampling channel 11 corresponds to the position of the sampling frame 30.

[0078] The sampling container 40 is detachably installed in the sampling frame 30, and the sampling port of the sampling container 40 is flush with the sampling end of the sampling frame 30. The sampling container 40 has a sampling drive device 41 and a sampling track mechanism 42. The sampling drive device 41 is drivenly connected to the sampling frame 30 and is used to drive the sampling frame 30 through the sampling channel 11 and insert it into the wall of the sampling hole. The sampling track mechanism 42 is connected to the sampling frame 30.

[0079] The storage mechanism 50 is located above the sampling frame 30 and is used to store the sampling container 40, which facilitates the management and replacement of the sampling container.

[0080] The loading and unloading mechanism 60 is located at the other end of the sampling frame 30 opposite to the sampling end. It is used to move the empty sampling container 40 from the storage mechanism 50 into the sampling frame 30, and to move the sampling container 40 after sampling from the sampling frame 30 into the storage mechanism 50, thereby realizing the automatic replacement of the sampling container.

[0081] During sampling, the loading container 10 is first hoisted using ropes. Operators move the loading container 10 according to the predetermined sampling depth and position, bringing it to the target sampling location within the sampling hole. Once the loading container 10 reaches the sampling location, the fixing mechanism 20 is activated, extending from the loading container 10 until it is fixed to the sampling hole wall. The loading / unloading mechanism 60 then begins operation, removing an empty sampling container 40 from the storage mechanism 50 and moving it into the sampling outer frame 30. The sampling drive device 41 is then activated, driving the sampling outer frame 30 through the sampling channel 11 and inserting it into the sampling hole wall. The rare earth mineral sample enters the sampling container 40 through its sampling port. After sampling, the sampling drive device 41 reverses its direction, causing the sampling outer frame 30 to exit from the sampling hole wall back into the loading container 10. The sample remains in the sampling container 40, thus obtaining the sample. The loading and unloading mechanism 60 restarts, removing the sampled container 40 from the sampling frame 30 and moving it to the storage mechanism 50. The loading and unloading mechanism 60 then removes the empty sampled container 40 from the storage mechanism 50 and moves it back into the sampling frame 30. The fixing mechanism 20 is released from its fixation to the sampling hole wall. The loading box 10 is adjusted using ropes to change its sampling position within the sampling hole. Once the new sampling position is reached, the fixing mechanism 20 is re-fixed to the sampling hole wall. The sampling drive device 41 is then activated, driving the sampling frame 30 through the sampling channel 11 and inserting it into the sampling hole wall. The rare earth ore sample enters the sampled container 40 through its sampling port. Through these steps, continuous sampling at different locations can be completed. After all sampling is completed, the fixing mechanism 20 is released from its fixation to the sampling hole wall, and the loading box 10 is hoisted out of the sampling hole using ropes, completing the entire drilling and sampling process.

[0082] In this embodiment, the sampling track mechanism 42 is designed to ensure the stability of the sampling outer frame 30 when it moves.

[0083] It should be noted that the sampling hole in this embodiment is a shallow borehole, and the sampling frame 30 is inserted into the sampling hole wall, which is a soil-type hole wall. For soil layers containing a large number of stones, the stones at the sampling location can be crushed beforehand. After crushing, the sample is then taken through this device. At the same time, when the sampling container 40 takes a sample, it is directly inserted into the soil layer. When it is removed, the sample will automatically follow the sampling container 40 out due to factors such as the friction of the inner wall of the sampling container 40, thereby completing the sample collection.

[0084] In this embodiment, the loading box 10 is a rectangular box, and electronic equipment and controllers that cooperate with various mechanisms are also installed inside the box. The power supply of the equipment can be arranged externally through the wires and the suspension ropes, that is, the wires are pulled into the equipment from outside the hole.

[0085] In some alternative embodiments, the sampling drive device 41 includes a sampling drive motor 411 and a sampling drive gear. The sampling drive gear is driven and connected to the sampling drive motor 411. The bottom of the sampling frame 30 is provided with a toothed groove, and the sampling drive gear is meshed with the toothed groove at the bottom of the sampling frame 30.

[0086] The sampling drive motor 411 drives the sampling drive gear to rotate, thereby moving the sampling frame 30. The sampling drive motor 411 is located at the bottom of the sampling frame 30, close to the sampling channel 11. During setup, the length of the sampling frame 30, the width of the loading box 10, and the sampling depth need to be configured to ensure that the movement of the sampling frame 30 is unrestricted.

[0087] The sampling track mechanism 42 includes a sampling main track 421 and a sampling slider. The sampling main track 421 is set inside the loading box 10 and is parallel to the sampling outer frame 30. The sampling slider is connected to the side of the sampling outer frame 30 and is slidably connected to the sampling main track 421.

[0088] The sampling main track 421 includes a U-shaped structure, and the sampling slider is a rectangular strip structure that is engaged in a groove within the sampling main track 421. When the sampling drive device 41 drives the sampling outer frame 30 to move, the sampling slider slides along the sampling main track 421. The sampling main track 421 provides precise guidance for the movement of the sampling outer frame 30, ensuring that the sampling outer frame 30 maintains a straight line during movement without deviation or shaking. The sampling main track 421 can be fixed inside the loading box 10 by a mounting bracket. The entire structure of the sampling main track 421 is located within the loading box 10. The sampling slider is connected to one side wall of the sampling outer frame 30, and limit structures are provided at both ends of the sampling main track 421 to prevent the sampling slider from falling off.

[0089] In some optional embodiments, the storage mechanism 50 includes a storage component 501, adhesive strips 503, and a storage motor 504. The storage component 501 includes a hollow cylindrical structure with a hollow space. The outer wall of the storage component 501 is provided with multiple storage slots 502, which are arranged in a ring and at uniform intervals. Adhesive strips 503 are provided on both side walls at the outlet of the storage slots 502. The sampling container 40 is placed in the storage slot 502 and fixed in the storage slot 502 by the adhesive strips 503. Each storage slot 502 can be provided with a sampling container 40. The storage motor 504 is located in the hollow space of the storage component 501 and is drivenly connected to the storage component 501. The storage motor 504 is also connected to the mounting bracket provided in the loading box 10.

[0090] The storage container 501 is a hollow cylindrical structure with multiple storage slots 502 arranged in a ring and at uniform intervals on its outer side wall. Each storage slot 502 has adhesive strips 503 on both sides of its outlet. The sampling container 40 is placed inside the storage slot 502 and secured by the adhesive strips 503. The sampling container 40 is sized to fit the storage slot 502, ensuring a tight fit and preventing the sampling container 40 from shaking during storage. The adhesive strips 503 at the opening of the storage slot 502 also act as a barrier, securing the sampling container 40 within it. Removing or placing the sampling container 40 requires pressing firmly to release it from or into the storage slot 502.

[0091] The length of the adhesive strip 503 is set to be the same as the length of the storage slot 502, which in turn is set to be the same as the length of the sampling container 40. The end of the storage slot 502 near the sampling channel 11 is designed as a closed structure to prevent sample leakage from the end of the sampling container 40. The adhesive strip 503 also prevents the sampling container 40 from moving after sampling.

[0092] When sampling container 40 needs to be retrieved, storage motor 504 starts, driving storage component 501 to rotate. By rotating storage component 501, sampling containers 40 in storage slot 502 can be moved sequentially to a predetermined position for operation by loading / unloading mechanism 60. In this embodiment, the circular storage component 501 can achieve the effect of retrieving and placing sampling containers 40 at the same position (i.e., a fixed position above loading / unloading mechanism 60).

[0093] In some optional embodiments, the loading and unloading mechanism 60 includes an insert plate 601, a loading and unloading motor 603, a cross slide rail 604, and a directional slider device 605; wherein, the bottom of the insert plate 601 is connected to a handle 602, and one end of the insert plate 601 extends out of the handle 602; the loading and unloading motor 603 is connected to the insert plate 601 and is used to drive the insert plate 601 to rotate; the vertical track of the cross slide rail 604 is connected to the loading and unloading motor 603; the directional slider device 605 is slidably connected to the sampling track mechanism 42, and a rising bracket is connected to the directional slider device 605, the rising bracket being connected to the horizontal track of the cross slide rail 604;

[0094] In some optional embodiments, the sampling frame 30 includes a rectangular box structure, the top wall of the sampling frame 30 is openable, the top wall of the sampling frame 30 is hinged to one side wall of the sampling frame 30, the side of the top wall of the sampling frame 30 and the top surface of the sampling container 40 are provided with corresponding magnets 608 for locking the sampling container 40 inside the sampling frame 30, the top position of the sampling container 40 and the sampling frame 30 are also spaced apart to form a first insertion space 606; the other end of the sampling container 40 includes a sealing member, the sealing member is recessed, so that the other end of the sampling container 40 has a second insertion space 607; the insert plate 601 can be inserted into the first insertion space 606, and the insert 602 can be inserted into the second insertion space 607.

[0095] In some alternative embodiments, the directional slider device 605 includes a directional slider and a built-in driver, which drives the directional slider to slide, thereby moving the cross slide rail 604. The cross slide rail 604 is a slide rail structure in the prior art that can move in two directions.

[0096] In some alternative embodiments, when it is necessary to move an empty sampling container 40 from the storage mechanism 50 to the sampling outer frame 30, the directional slider device 605 drives the cross slide rail 604 and the insert plate 601 to a position close to the storage mechanism 50. Then, the cross slide rail 604 moves, causing the insert plate 601 to move to a position facing the end of the sampling container 40. At this time, the directional slider device 605 moves toward the sampling container 40, so that the insert plate 601 is inserted into the outer top surface of the sampling container 40, and the insert 602 is inserted into the second insertion space 607. The insertion plate 601 and the insert 602 cooperate to clamp the sampling container 40, so that it can be moved by the insert 602. The insert plate 601 and the handle 602 drive the sampling container 40 to move downwards, and the top wall of the sampling outer frame 30 is in the open state. The opening angle of the top wall of the sampling outer frame 30 is set to be greater than 90 degrees to facilitate the sampling container 40 to enter the sampling outer frame 30. After entering the sampling outer frame 30, the handle 602 and the insert plate 601 disengage from the sampling container 40. The directional slider device 605 and the cross slide rail 604 are controlled to cooperate, thereby moving the handle 602 to the side of the top wall of the sampling outer frame 30, that is, to one side of the outer top surface of the sampling outer frame 30 when the top wall of the sampling outer frame 30 is in the closed state. The cross slide rail 604 is controlled to move, pushing the top wall of the sampling outer frame 30 to rotate, and then closing the top wall of the sampling outer frame 30.

[0097] When the sampling container 40 is removed from the sampling frame 30, the directional slider device 605 drives the cross slide rail 604 and the insert plate 601 to move, so that the insert plate 601 is inserted into the first insertion space 606 formed between the sampling container 40 and the top of the sampling frame 30, and the insert 602 is inserted into the second insertion space 607 at the other end of the sampling container 40. Then, through the vertical and horizontal movement of the cross slide rail 604 and the sliding of the directional slider device 605 on the sampling track mechanism 42, the sampling container 40 is moved out of the sampling frame 30. Continuing to move upward, the sampling container 40 can be placed into the storage mechanism 50.

[0098] The top wall of the sampling frame 30 is openable. By attracting the sampling container 40 or the magnet 608 on the top side wall of the sampling frame 30, the sampling container 40 can be locked inside the sampling frame 30.

[0099] In some optional embodiments, the sampling end of the sampling frame 30 is connected to a U-shaped protrusion 31. The cross-sectional shape of the protrusion 31 is the same as that of the sampling frame 30. The inner walls of the protrusion 31 on three sides are provided with grooves 311, forming a U-shaped groove. A slider 314 is provided in the groove 311 on one vertical inner wall. Rope holes are provided on both side walls of the sampling frame 30, extending from the sampling end of the sampling frame 30 to the opposite end. These rope holes are connected to a transition hole on the end face of the protrusion 31 opposite to the sampling frame 30. The connection hole includes two holes, which are located at the bottom of the slide grooves 311 on the two vertically opposite side walls of the protruding frame 31. The connection hole is connected to the slide grooves 311. A pull rope 312 is inserted into the rope hole on one side, passes through the connection hole on one side and enters the slide groove 311 on the bottom wall of the protruding frame 31. It then passes out through the connection hole on the other side and out through the rope hole on the other side. The pull rope 312 is connected to the slide bar 314. The two ends of the pull rope 312 are respectively wound around the rotating shaft of the rope motor 313. The rope motor 313 is connected to the sampling frame 30.

[0100] In some alternative embodiments, a pull rope 312 is threaded through the rope hole. The pull rope 312 enters from one side of the rope hole, passes through the adapter hole into the slide groove 311 on the bottom wall of the protruding frame 31, and then exits from the other side of the adapter hole and the other side of the rope hole. The two ends of the pull rope 312 are respectively wound around the rotating shaft of the rope motor 313. When the rope motors 313 on both sides are started, they are configured to retract the pull rope 312 on one side and release the pull rope 312 on the other side, which allows the slider 314 to move from the vertical sidewall on one side of the protruding frame 31 to the vertical sidewall on the other side. Thus, the slider 314 creates a cutting effect. After the sampling container 40 completes the insertion action by inserting into the sampling hole wall and before the next pull-out action, the slider 314 cuts the sampling port of the sampling container 40. This severs the connection between the sample inside the sampling container 40 and the sample not yet in the sampling container 40, improving the integrity of the sample collected by the sampling container 40. Furthermore, anti-slip textures can be provided on the inner wall of the sampling container 40 to further enhance the integrity of the sample collected.

[0101] In some alternative embodiments, the fixing mechanism 20 includes a fixing motor 201, a pressing member 202, and a connection release mechanism; the fixing motor 201 is connected to a mounting bracket provided in the loading box 10; the pressing member 202 is provided with an insertion hole, the drive shaft of the fixing motor 201 passes through the insertion hole, and the pressing member 202 is slidably connected to the drive shaft of the fixing motor 201; the connection release mechanism is configured to connect the pressing member 202 to the drive shaft of the fixing motor 201, and disconnect the connection between the pressing member 202 and the drive shaft of the fixing motor 201 after the blocking force received by the pressing member 202 exceeds a predetermined value, so that the drive shaft of the fixing motor 201 continues to move through the insertion hole. The connection release mechanism includes: a friction assembly 203 connected to the drive shaft of a fixed motor 201; two first friction elements 204 respectively disposed on opposite sides outside the friction assembly 203; a limiting slide 205, one end of which is connected to the pressing member 202 and the other end of which is slidably connected to the first friction elements 204, the sliding of the first friction elements 204 being able to move closer to and further away from the friction assembly 203; and a fixed drive mechanism 206 connected to the pressing member 202 and drivenly connected to the first friction elements 204.

[0102] In some optional embodiments, the fixed drive mechanism 206 includes a pressing motor and a connecting frame. The connecting frame is connected to the pressing motor and to the pressing member 202. A pressing frame is connected to the drive shaft of the pressing motor. The pressing frame can abut against the first friction member 204. When the pressing frame abuts against the first friction member 204, the first friction member 204 is in frictional contact with the friction assembly 203. When the first friction member 204 and the friction assembly 203 slide relative to each other, frictional resistance is generated between the first friction member 204 and the friction assembly 203. When the fixed motor 201 extends outward, it drives the pressing member 202 to move together. When the pressing member 202 presses against the sampling hole wall, it applies a pressing force to the sampling hole wall (at this time, the pressing member 202 is subjected to a blocking force), making the sampling hole wall under the pressing member 202 compact. When the pressing force is greater than the frictional resistance generated between the first friction element 204 and the friction assembly 203, the first friction element 204 and the friction assembly 203 slide. At this time, the pressing element 202 and the drive shaft of the fixed motor 201 move. The end of the drive shaft of the fixed motor 201 is also connected to a plug rod, which can be inserted into the wall of the sampling hole to produce a fixing effect.

[0103] In this embodiment, the magnitude of the frictional resistance between the first friction element 204 and the friction assembly 203 can be achieved by adjusting the movement of the downward-pressing motor. Additionally, a laser ranging sensor can be installed; when relative sliding between the first friction element 204 and the friction assembly 203 is detected, the downward-pressing motor can be raised. This prevents excessive friction and wear between the first friction element 204 and the friction assembly 203.

[0104] In this embodiment, multiple sets of fixing mechanisms 20 can be provided, with at least one fixing mechanism 20 provided on each of the opposite sides of the loading box 10, so as to achieve stable fixing of the loading box 10.

[0105] The connection between the limiting slide 205 and the first friction member 204 is a cross structure. The first friction member 204 has a corresponding cross hole, and the cross structure connects with the cross hole, allowing the limiting slide 205 to be fixed in a direction parallel to the drive shaft of the fixed motor 201. This configuration allows the first friction member 204 to move perpendicular to the drive direction of the fixed motor 201, while remaining fixed in a direction parallel to the drive shaft of the fixed motor 201.

[0106] The friction assembly 203 includes a friction plate, which is connected to the drive shaft of the fixed motor 201.

[0107] This application also provides a drilling sampling method for geological exploration of ion-adsorption rare earth minerals, which uses the aforementioned drilling sampling method for geological exploration of ion-adsorption rare earth minerals to sample rare earth minerals; the sampling method includes the following steps:

[0108] The loading box 10 is hoisted using ropes. The operator moves the loading box 10 according to the predetermined sampling depth and position so that the loading box 10 reaches the target sampling position in the sampling hole.

[0109] When the loading box 10 reaches the sampling position, the fixing mechanism 20 is activated. The fixing mechanism 20 extends out of the loading box 10 until it is fixed on the wall of the sampling hole.

[0110] The loading and unloading mechanism 60 starts working, takes out an empty sampling container 40 from the storage mechanism 50, and moves the empty sampling container 40 into the sampling outer frame 30;

[0111] Start the sampling drive device 41. The sampling drive device 41 drives the sampling outer frame 30 through the sampling channel 11 and inserts it into the sampling hole wall. The rare earth mineral sample enters the sampling container 40 through the sampling port of the sampling container 40.

[0112] After sampling is completed, the sampling drive device 41 drives in reverse, causing the sampling frame 30 to exit from the sampling hole wall and into the loading box 10;

[0113] The loading and unloading mechanism 60 is restarted to remove the sampling container 40 from the sampling frame 30 after the sample has been collected and move it to the storage mechanism 50 for storage.

[0114] When sampling at the next location, the fixing mechanism 20 repeats the fixing step and takes out a new sampling container 40 from the storage mechanism 50 and installs it into the sampling frame 30 to complete the continuous sampling steps.

[0115] Once all sampling work is completed, the fixing mechanism 20 is released from the sampling hole wall, and the loading box 10 is hoisted out of the sampling hole using ropes, thus completing the entire drilling and sampling process.

[0116] The method provided in this embodiment uses a detachable sampling container 40, with each sampling container 40 used only to collect a sample from one location. After one sampling is completed, the sampling container 40 is removed from the sampling frame 30 and stored separately via the loading and unloading mechanism 60, and then a new sampling container 40 is used for the next sampling. This method fundamentally avoids cross-contamination between samples from different locations, ensuring that each sample accurately represents the original composition of the ore body at the corresponding depth, thereby improving the accuracy and reliability of rare earth resource exploration data.

[0117] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
