Description

Technical Field

[0001] The present application belongs to the technical field of rare earth ore drilling and sampling, and specifically relates to a drilling and sampling device and a sampling method for geological exploration of ionic rare earth ore. Background Art

[0002] Due to their unique physical and chemical properties, rare earth elements (REEs) play an irreplaceable and important role in modern industry and are widely used in advanced technologies such as electronics, aerospace, and new energy. REEs are widely and unevenly distributed in the Earth's crust. Ionic rare earth ores, a key type of rare earth resource, are rich in heavy rare earth elements such as dysprosium (Dy), terbium (Tb), and europium (Eu). These elements have critical applications in high-tech fields and are difficult to replace with other elements. Therefore, the exploration of ionic rare earth ores is crucial for the rational development and utilization of rare earth resources.

[0003] Ionic rare earth ores are typically found within the weathering crust of granite or volcanic rocks. These ore bodies exhibit a loose, porous, muddy structure composed primarily of clay minerals. The rare earth elements (REEs) are adsorbed onto the surfaces of clay particles as ions, rather than as solid minerals. This unique occurrence makes REEs more readily available for extraction during weathering, but it also presents unique challenges for exploration and sampling.

[0004] During the exploration process, continuous pollution-free sampling at different depths is a key step in evaluating ore grade and distribution. However, existing technologies have significant deficiencies in the sampling process. Traditional methods usually use fixed sampling containers for multiple sampling. After the container repeatedly contacts the ore body at different locations, the residual rare earth soil will cause subsequent samples to be contaminated and cannot truly reflect the original composition of the ore body at each depth. In addition, traditional sampling methods such as manual sampling with a Luoyang shovel are not only inefficient and costly, but also have a short sampling length, which is difficult to meet the needs of deep exploration, seriously affecting the 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 needs to be urgently solved by those skilled in the art. Summary of the Invention

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

[0075] The loading box 10 is hoisted and moved by ropes, so as to facilitate flexible transfer between different sampling locations;

[0076] The fixing mechanism 20 is disposed in the loading box 10 and is configured to extend from the loading box 10 and be fixed to the wall of the sampling hole when the loading box 10 reaches the sampling position in the sampling hole, thereby ensuring the stability of the sampling process;

[0077] The sampling outer frame 30 is disposed in the loading box 10. The side wall of the loading box 10 is provided with a sampling channel 11. The location of the sampling channel 11 corresponds to the location of the sampling outer frame 30.

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

[0079] The storage mechanism 50 is provided above the sampling outer frame 30 and is used to store the sampling container 40, so as to facilitate the management and replacement of the sampling container;

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

[0081] When sampling is implemented, the loading box 10 is first hoisted using a rope. 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. When the loading box 10 reaches the sampling position, the fixing mechanism 20 is started, and the fixing mechanism 20 extends from the loading box 10 until the fixing mechanism 20 is fixed on the wall of the sampling hole. The loading and unloading mechanism 60 starts to work, takes out an empty sampling container 40 from the storage mechanism 50, and moves the empty sampling container 40 to the sampling outer frame 30. The sampling drive device 41 is started, and the sampling drive device 41 drives the sampling outer frame 30 to pass through the sampling channel 11 and insert into the wall of the sampling hole. The rare earth mineral sample enters the sampling container 40 through the sampling port of the sampling container 40. After sampling is completed, the sampling drive device 41 drives in the reverse direction, so that the sampling outer frame 30 withdraws from the wall of the sampling hole into the loading box 10, and the sample in the sampling container 40 is left in the sampling container 40, thereby obtaining the sample. The loading and unloading mechanism 60 is activated again, removing the sampled sampling container 40 from the sampling outer frame 30 and moving it to the storage mechanism 50 for storage. The loading and unloading mechanism 60 then removes the empty sampling container 40 from the storage mechanism 50 and moves it to the sampling outer frame 30. The securing mechanism 20 is released from the sampling hole wall, and the loading box 10 is adjusted to its sampling position within the sampling hole using a rope. After reaching the new sampling position, the securing mechanism 20 is re-secured to the sampling hole wall, and the sampling drive 41 is activated. The sampling drive 41 drives the sampling outer frame 30 through the sampling channel 11 and into the sampling hole wall. The rare earth ore sample enters the sampling container 40 through the sampling port of the sampling container 40. Through these steps, continuous sampling at different locations is achieved. When all sampling is completed, the securing mechanism 20 is released from the sampling hole wall, and the loading box 10 is hoisted out of the sampling hole using a rope, completing the entire drilling sampling process.

[0082] In this embodiment, the sampling track mechanism 42 is provided to ensure the stability of the sampling outer frame 30 during movement.

[0083] It should be noted that the sampling hole in this embodiment is a shallow drill hole, and the wall of the sampling hole into which the sampling outer frame 30 is inserted is a soil type hole wall. For soil layers containing a large number of stones, the stones at the sampling position can be crushed in advance. After crushing, sampling can be performed through this equipment. At the same time, when the sampling container 40 is sampling, the sampling container 40 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 and other components that cooperate with various mechanisms are also provided in the box. The power supply of the equipment can be arranged externally through wires following the suspension rope, that is, the wires are pulled into the equipment from outside the hole.

[0085] In some optional 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. A tooth groove is provided at the bottom of the sampling outer frame 30, and the sampling drive gear is meshed and connected with the tooth groove at the bottom of the sampling outer frame 30.

[0086] The sampling drive motor 411 rotates the sampling drive gear, thereby driving the movement of the sampling outer frame 30. The sampling drive motor 411 is located at the bottom of the sampling outer frame 30, near the sampling channel 11. During configuration, the length of the sampling outer frame 30, the width of the loading box 10, and the sampling depth must be configured while ensuring unrestricted movement of the sampling outer frame 30.

[0087] The sampling track mechanism 42 includes a sampling main track 421 and a sampling slide. The sampling main track 421 is arranged in the loading box 10 and is parallel to the sampling outer frame 30. The sampling slide 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 slide is a rectangular bar structure, and the sampling slide is stuck in the groove of the sampling main track 421. When the sampling drive device 41 drives the sampling outer frame 30 to move, the sampling slide will slide 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 always maintains linear motion during the movement without offset or shaking. The sampling main track 421 can be fixed in the loading box 10 through a mounting bracket. The overall structure of the sampling main track 421 is located in the loading box 10. The sampling slide is connected to one of the side walls of the sampling outer frame 30, and a limiting structure is provided at both ends of the sampling main track 421 to prevent the sampling slide from falling off.

[0089] In some optional embodiments, the storage mechanism 50 includes a storage piece 501, a rubber strip 503, and a storage motor 504; wherein, the storage piece 501 includes a hollow cylindrical structure, the hollow cylindrical structure has a hollow space, and the outer wall of the storage piece 501 is provided with a plurality of storage slots 502, and the plurality of storage slots 502 are arranged in a circular and evenly spaced manner, and the side walls on both sides of the outlet of the storage slot 502 are provided with a rubber strip 503, the sampling container 40 is arranged in the storage slot 502, and is fixed in the storage slot 502 by the rubber strip 503, and a sampling container 40 can be set in each storage slot 502; the storage motor 504 is arranged in the hollow space of the storage piece 501, and is driven and connected to the storage piece 501, and the storage motor 504 is also connected to the mounting bracket arranged in the loading box 10.

[0090] The storage unit 501 is a hollow cylindrical structure, and its outer wall is provided with a plurality of storage slots 502 arranged in a circular and evenly spaced manner. Each storage slot 502 has a rubber strip 503 on both sides of the sidewall at the exit. The sampling container 40 is placed in the storage slot 502 and fixed by the rubber strip 503. The sampling container 40 is adapted to the storage slot 502 in size, so that the sampling container 40 and the storage slot 502 fit together, which prevents the sampling container 40 from shaking when stored. At the same time, the rubber strip 503 is provided at the opening of the storage slot 502, which can block the sampling container 40 in the storage slot 502 and ultimately fix the sampling container 40. To remove or place the sampling container 40, it is necessary to press the sampling container 40 hard to make it fall out of or enter the storage slot 502.

[0091] The length of the rubber strip 503 is set to be the same as the length of the storage groove 502, and the length of the storage groove 502 is also set to be the same as the length of the sampling container 40. The end of the storage groove 502 near the sampling channel 11 is configured as a closed structure to prevent the sample in the sampling container 40 from leaking out of the end. The rubber strip 503 also prevents the movement of the sampling container 40 after sampling.

[0092] When a sampling container 40 is needed, the storage motor 504 is activated, driving the storage member 501 to rotate. By rotating the storage member 501, the sampling containers 40 in the storage slot 502 are sequentially moved to a predetermined position for operation by the loading and unloading mechanism 60. In this embodiment, the circular storage member 501 allows the sampling container 40 to be removed and placed in the same position (i.e., a fixed position above the loading and unloading mechanism 60).

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

[0094] In some optional embodiments, the sampling outer frame 30 includes a rectangular box structure, the top wall of the sampling outer frame 30 is openable, the top wall of the sampling outer frame 30 is hinged to one of the side walls of the sampling outer frame 30, and the side edges of the top wall of the sampling outer frame 30 and the top surface of the sampling container 40 are provided with corresponding magnets 608 for locking the sampling container 40 in the sampling outer frame 30. The sampling container 40 and the top position of the sampling outer frame 30 are also spaced to form a first plug-in space 606; the other end of the sampling container 40 includes a sealing piece, which is concavely arranged so that the other end of the sampling container 40 has a second plug-in space 607; the plug-in board 601 can be plugged into the first plug-in space 606, and the plug-in hand 602 can be plugged into the second plug-in space 607.

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

[0096] In some optional embodiments, when it is necessary to move the empty sampling container 40 from the storage mechanism 50 to the sampling outer frame 30, the directional slider device 605 drives the cross slide 604 and the insert plate 601 to move to a position close to the storage mechanism 50, and then the cross slide 604 structure moves, driving 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 hand 602 is inserted into the second insertion space 607. The insert plate 601 cooperates with the insert hand 602 to clamp the sampling container 40, and then it can be moved by the insert hand 602. The insert plate 601 and the hand 602 drive the sampling container 40 to move downward, and the top wall of the sampling outer frame 30 is in an open state. The opening angle of the top wall of the sampling outer frame 30 is set to be greater than ninety degrees, which is convenient for the sampling container 40 to enter the sampling outer frame 30. After entering the sampling outer frame 30, the hand 602 and the insert plate 601 are separated from the sampling container 40, and the directional slider device 605 and the cross slide rail 604 are controlled to cooperate, and then the hand 602 is moved to the side of the top wall of the sampling outer frame 30, that is, the side of the external top surface of the top wall of the sampling outer frame 30 in the closed state, and 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] To remove the sampling container 40 from the sampling frame 30, the directional slider assembly 605 drives the cross rail 604 and the insert plate 601, allowing the insert plate 601 to insert into the first insertion space 606 formed between the sampling container 40 and the top of the sampling frame 30, and the insert handle 602 to insert into the second insertion space 607 at the other end of the sampling container 40. The sampling container 40 is then removed from the sampling frame 30 by the vertical and lateral movement of the cross rail 604 and the sliding movement of the directional slider assembly 605 on the sampling track mechanism 42. Continuing upward movement, the sampling container 40 can be placed in the storage mechanism 50.

[0098] The top wall of the sampling outer frame 30 is openable, and the sampling container 40 is locked in the sampling outer frame 30 by adsorbing the sampling container 40 or the magnet 608 on the top surface of the side wall of the sampling outer frame 30 .

[0099] In some optional embodiments, the sampling end of the sampling outer frame 30 is connected to a U-shaped protruding frame 31, and the cross-sectional shape of the protruding frame 31 is the same as the cross-sectional shape of the sampling outer frame 30. The inner walls of the three sides of the protruding frame 31 are provided with sliding grooves 311, and the three sliding grooves 311 form a U-shaped groove. The sliding groove 311 of the vertical inner wall on one side is provided with a sliding bar 314, and the side walls of the sampling outer frame 30 are provided with rope holes. The rope holes pass through the sampling end of the sampling outer frame 30 to the other end opposite to it, and the rope holes are connected to the adapter holes provided on the end face of the protruding frame 31 relative to the sampling outer frame 30. There are two connecting holes, which are respectively located at the bottom of the slide groove 311 on the two vertically opposite side walls of the protruding frame 31. The adapter hole is connected to the slide groove 311, and a pull rope 312 is passed through the rope hole. The pull rope 312 enters from the rope hole on one side, passes through the adapter hole on one side, enters the slide groove 311 on the bottom wall of the protruding frame 31, passes through the adapter hole on the other side, and passes through the rope hole on the other side. The pull rope 312 is connected to the slide bar 314, and the two ends of the pull rope 312 are respectively wrapped around the rotating shaft of the rope motor 313, and the rope motor 313 is connected to the sampling outer frame 30.

[0100] In some optional embodiments, a pull rope 312 is threaded through the rope hole. The pull rope 312 enters from one rope hole, passes through the adapter hole, and enters the slide groove 311 on the bottom wall of the protruding frame 31. It then passes through the adapter hole on the other side and exits from the rope hole on the other side. The two ends of the pull rope 312 are respectively wrapped around the rotating shaft of the rope motor 313. When the rope motors 313 on both sides are activated, they are configured to retract the pull rope 312 on one side and release the pull rope 312 on the other side. This allows the slide bar 314 to move from the vertical side wall of the protruding frame 31 to the vertical side wall on the other side. In this way, the slide bar 314 can create a cutting effect. When the sampling container 40 is inserted into the wall of the sampling hole and the sampling is completed, before the next pulling-out action is performed, the slide bar 314 cuts the sampling port of the sampling container 40. This cuts off the connection between the sample in the sampling container 40 and the sample that has not entered the sampling container 40. This improves the sample recovery into the sampling container 40 and prevents part of the sample from escaping from the sampling container 40 when the sampling container 40 is pulled out, thereby improving the integrity of the sample collected by the sampling container 40. Anti-slip grooves can also be provided on the inner wall of the sampling container 40 to improve the integrity of the sample collected by the sampling container 40.

[0101] In some optional embodiments, the fixing mechanism 20 includes a fixed motor 201, a pressing piece 202 and a connection and release mechanism; the fixed motor 201 is connected to a mounting bracket provided in the loading box 10; the pressing piece 202 is provided with an insertion hole, and the drive shaft of the fixed motor 201 is inserted into the insertion hole, and the pressing piece 202 is slidingly connected to the drive shaft of the fixed motor 201; the connection and release mechanism is configured to connect the pressing piece 202 to the drive shaft of the fixed motor 201, and after the blocking force applied to the pressing piece 202 exceeds a predetermined value, the connection between the pressing piece 202 and the drive shaft of the fixed motor 201 is disconnected, so that the drive shaft of the fixed motor 201 continues to move through the insertion hole. The connection and release mechanism includes: a friction component 203, connected to the drive shaft of the fixed motor 201; two first friction parts 204, respectively arranged on opposite sides outside the friction component 203; a limiting slide 205, one end of which is connected to the pressing part 202 and the other end is slidingly connected to the first friction part 204, and the sliding of the first friction part 204 can move closer to and away from the friction component 203; a fixed driving mechanism 206, connected to the pressing part 202, and driven by the first friction part 204.

[0102] In some optional embodiments, the fixed drive mechanism 206 includes a downward pressing motor and a connecting frame, the connecting frame being connected to the downward pressing motor, which is connected to the pressing member 202. A pressing frame is connected to the driving shaft of the downward pressing motor, and 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 frictionally connected to 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 wall of the sampling hole, it applies a pressing force to the wall of the sampling hole (at this time, the pressing member 202 is subjected to a blocking force), so that the wall of the sampling hole under the pressing member 202 becomes tight. When the pressing force is greater than the friction resistance generated between the first friction member 204 and the friction assembly 203, the first friction member 204 and the friction assembly 203 slide. At this time, the pressing member 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 an insertion 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 member 204 and the friction assembly 203 can be controlled by the movement of the push-down motor. Furthermore, a laser rangefinder sensor can be provided. When a relative sliding movement between the first friction member 204 and the friction assembly 203 is detected, the push-down motor is raised, thereby preventing the first friction member 204 and the friction assembly 203 from excessive friction and wear.

[0104] In this embodiment, multiple groups of fixing mechanisms 20 may be provided, and fixing mechanisms 20 are provided at least on two opposite sides of the loading box 10 to achieve stable fixation 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. The cross structure and the cross hole are connected together, so that the limiting slide 205 is fixed in a direction parallel to the drive shaft of the fixed motor 201. This arrangement allows the first friction member 204 to move perpendicular to the drive direction of the fixed motor 201 and be 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 a drive shaft of the fixed motor 201 .

[0107] The present application also provides a drilling sampling method for geological exploration of ionic rare earth minerals, which uses the aforementioned drilling sampling method for geological exploration of ionic rare earth minerals to sample rare earth minerals; the sampling method comprises the following steps:

[0108] The loading box 10 is hoisted by a rope, and 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 and extends from the loading box 10 until the fixing mechanism 20 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] The sampling drive device 41 is started, and the sampling drive device 41 drives the sampling outer frame 30 to pass through the sampling channel 11 and insert into the wall of the sampling hole, and the rare earth mineral sample enters the sampling container 40 through the sampling port of the sampling container 40;

[0112] After the sampling is completed, the sampling drive device 41 drives in the reverse direction, so that the sampling outer frame 30 is withdrawn from the wall of the sampling hole into the loading box 10;

[0113] The loading and unloading mechanism 60 is started again to take the sample container 40 after sampling from the sampling outer frame 30 and move it to the storage mechanism 50 for storage;

[0114] When sampling at the next position, the fixing mechanism 20 performs the fixing step again, and takes out a new sampling container 40 from the storage mechanism 50 and installs it in the sampling outer frame 30, completing the continuous sampling step;

[0115] When all sampling work is completed, the fixing state between the fixing mechanism 20 and the wall of the sampling hole is released, and the loading box 10 is hoisted out of the sampling hole using a rope, completing the entire drilling sampling process.

[0116] The method provided in this embodiment utilizes removable sampling containers 40, each of which is used to collect samples from a single location. After completing a sampling operation, the loading and unloading mechanism 60 removes the sampling container 40 from the sampling frame 30 and stores it separately, before replacing it with a new one for the next sampling operation. This approach fundamentally prevents 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 implementation methods further illustrate the purpose, technical solutions and beneficial effects of this application in detail. It should be understood that the above are only specific implementation methods of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
