In the exploration process, accurate acquisition of ore sample information is a key link in understanding the characteristics of the ore deposit, reserves, and other conditions. Traditional drilling sampling methods have many shortcomings when targeting ionic rare earth ores. For example, using a rope descent method, the existing drilling sampling device is not accurate enough when locating the sampling point.

[0043] Compared with the prior art, the drilling sampling device and method for ionic rare earth mineral exploration provided by the present invention can achieve at least one of the following beneficial effects:

[0044] 1. The lifting track is positioned by using a positioning frame with two collinear fixed points above the sampling hole, and the lifting track can be extended to the bottom of the sampling hole, so that the entire drilling sampling device can be accurately positioned before sampling. Compared with some traditional drilling sampling methods with inaccurate positioning, such as rope descent with large position deviations, this precise positioning can effectively reduce the error of the sampling point and ensure that the sampling operation is carried out at the predetermined accurate position, thereby improving the accuracy and reliability of sampling. The sampling base can be accurately lifted and moved to the specified depth position according to the settings. Combined with the ring cutting operation of the cutting mechanism, the rare earth sample on the wall of the sampling hole at the specified depth position can be completely cut and separated from the hole wall.

[0045] 2. The collection mechanism closely follows the cutting mechanism to synchronously collect the cut rare earth samples, effectively avoiding the omission or scattering of samples, and realizing the efficient and complete collection of rare earth samples.

[0046] 3. The layered storage function of the storage institution can store the rare earth samples collected by the collection institution at different depths in layers, and clearly distinguish the samples at different depths. In this way, when the samples are analyzed later, separate studies can be conducted on samples at different depths, such as analyzing the changes in the content of rare earth elements and the differences in mineralization degree at different depths.

[0061] The drilling sampling device involved in the present invention has good adaptability in the field of ionic rare earth mineral exploration and can be widely used in a variety of complex geological environments. When encountering strata with ionic rare earth minerals such as hard soil and weathered rocks, the cutting mechanism 20 can perform precise ring cutting operations by virtue of its operating characteristics, thereby completely separating the rare earth sample from the hole wall of the sampling hole, and the purpose of sample collection can be achieved by relying on the collection mechanism 30, thereby ensuring the quality and representativeness of the collected rare earth samples.

[0062] A specific embodiment of the present invention, as Figures 1 to 5 As shown, a drilling sampling device for ionic rare earth mineral exploration is disclosed, comprising:

[0063] The lifting track 10 is positioned above the sampling hole using two fixed points on the upper and lower lines by using a positioning frame, and the lifting track 10 extends to the bottom of the sampling hole;

[0064] The sampling base 11 has a built-in lifting driver. The sampling base 11 is lifted and moved to a specified depth position on the lifting track 10 by the driver.

[0065] The cutting mechanism 20 is arranged on the sampling base 11 and is used for cutting the rare earth sample of the hole wall at a specified depth position in the sampling hole;

[0066] The collecting mechanism 30 is disposed on the sampling base 11 and moves along with the cutting mechanism 20 to collect the rare earth sample cut by the cutting mechanism 20;

[0067] The storage mechanism 40 is disposed on the sampling base 11 and is used to store the rare earth samples recovered from the collecting mechanism 30 in layers. The collecting mechanism 30 is disposed above the storage mechanism 40, so that the samples can be dropped conveniently.

[0068] Compared with the prior art, the drilling and sampling device for ionic rare earth mineral exploration provided in this embodiment can realize precise positioning of the sampling position through the positioning of the lifting track 10 and the lifting design of the sampling base 11. In conjunction with the cutting mechanism 20, the collecting mechanism 30 and the storage mechanism 40, it can efficiently and completely collect and store rare earth samples in layers, thereby improving the sampling accuracy and the convenience of subsequent analysis.

[0069] In this embodiment, the positioning frame accurately determines the position of the lifting track 10 above the sampling hole, so that it can be stably and vertically extended to the bottom, becoming a reliable guide rail for the movement of the sampling base 11. After receiving the control instruction, the built-in lifting driver of the sampling base 11 drives the sampling base 11 to accurately lift and lower along the lifting track 10 to reach the predetermined sampling depth position. The cutting mechanism 20 then performs a circular cutting operation on the rare earth sample of the hole wall at that position to separate the sample from the hole wall. The collection mechanism 30 closely follows the action of the cutting mechanism 20 to collect the samples generated by cutting in real time. Finally, the storage mechanism 40 performs layered storage according to the sample collection depth to ensure effective distinction of samples at different depths.

[0070] In this embodiment, the lifting track 10 is an I-beam structure, and a rack is installed on one side or both sides of the I-beam along the length direction, and a matching gear and a driving motor are installed on the sampling base 11. The driving motor is connected to the gear. When the motor is started, it drives the gear to rotate on the rack, so that the sampling base 11 can achieve lifting movement along the rack on the lifting track 10. The sampling base 11 has a certain strength and rigidity. The bottom or side of the sampling base is provided with a connection and support structure that is compatible with the gear transmission mechanism to ensure stability and reliability during the lifting process and avoid the accuracy of sampling being affected by external interference or self-vibration. At the same time, sufficient space and installation interfaces are provided on the sampling base 11 to stably install components such as the cutting mechanism 20, the collecting mechanism 30 and the storage mechanism 40, so as to ensure that the various mechanisms of the entire drilling sampling device can work together and operate normally when performing sampling tasks at different heights.

[0071] In some embodiments, the cutting mechanism 20 includes: an annular track 201, connected to the sampling base 11; an circumferential drive device 202, movably connected to the annular track 201; a radial screw mechanism 203, connected to the circumferential drive device 202, and capable of reciprocating along the radial direction of the annular track 201; a connecting frame assembly 204, connected to the moving seat of the radial screw mechanism 203; a cutting drill bit mechanism 205; connected to the connecting frame assembly 204, and configured to move circumferentially along the hole wall to form a circular trajectory under the drive of the circumferential drive device 202, and the rare earth on the hole wall within its moving range is broken; a baffle plate 206, connected to the connecting frame assembly 204, and the cutting drill bit mechanism 205 passes through the baffle plate 206. When the cutting drill bit mechanism 205 is cutting, the baffle plate 206 is close to the hole wall near the cutting position to block the broken soil after cutting; wherein, the radial screw mechanism 203 is used to control the cutting depth and reset of the cutting drill bit mechanism 205.

[0072] The coordinated operation of the annular track 201 and the surrounding drive device 202 enables the cutting drill mechanism 205 to stably and accurately form a circular track along the circumference on the hole wall, realize the uniform crushing of rare earth, and improve the uniformity and integrity of cutting. The radial screw mechanism 203 accurately controls the cutting depth and reset, giving the device the ability to select different sample amounts. The main function of the baffle plate 206 is to fit tightly to the hole wall near the cutting position when the cutting mechanism 20 performs the rare earth sample ring cutting operation on the hole wall. Through this close fit, the baffle plate 206 can effectively prevent the broken soil generated during the cutting process from falling. In an actual sampling environment, if there is no protection of the baffle plate 206, the broken soil generated by cutting is likely to be scattered directly, making it difficult for the collection mechanism 30 to collect the rare earth sample completely. The existence of the baffle plate 206 creates a relatively closed and clean sample collection space for the collection mechanism 30, ensuring that the rare earth sample cut by the cutting mechanism 20 can be smoothly collected by the collection mechanism 30.

[0073] The sampling base 11 serves as a bearing platform, and the annular track 201 builds a moving path for the surrounding drive device 202. The radial screw mechanism 203 is connected to the surrounding drive device 202, and the connecting frame assembly 204 on its moving seat carries the cutting drill mechanism 205 and the baffle plate 206. After the surrounding drive device 202 is started, it drives the cutting drill mechanism 205 to move at a uniform speed along the circumferential direction of the annular track 201 to form a circular cutting trajectory. The radial screw mechanism 203 accurately adjusts the radial position of the cutting drill mechanism 205 through its own telescopic movement, thereby controlling the cutting depth and realizing the reset operation. When cutting, the baffle plate 206 effectively blocks the splashing of broken soil produced by cutting by virtue of its close fit with the hole wall. The structure of the surrounding drive device 202 is also a combination of a drive motor and a drive gear.

[0074] An arc control mechanism 207 is connected to the back of the baffle plate 206 , and the arc control mechanism is configured to control the bending of both ends of the baffle plate 206 to adapt to the hole wall of the sampling hole with different curvatures.

[0075] In one of the optional embodiments, the curvature control mechanism 207 includes a curvature control motor 208, a traction rope and a screw. The baffle plate 206 includes an elastic metal plate, the middle part of the elastic metal plate is connected to the connecting frame assembly 204, and the screws are respectively connected to the two ends of the baffle plate 206. The curvature control motor 208 is connected to the part of the connecting frame assembly 204 extending to the two ends of the baffle plate 206. The traction rope is wrapped around and connected to the driving end of the curvature control motor 208, and the traction rope is also connected to the screw. After the driving end of the curvature control motor 208 rotates, the traction rope can be pulled to drive the two ends of the baffle plate 206 to bend.

[0076] The baffle plate 206 is made of an elastic metal plate, the middle part of which is firmly connected to the connecting frame assembly 204, and screws are connected at both ends. The curvature control motor 208 is installed at the connecting frame assembly 204 extending to the two ends of the baffle plate 206. When the drilling sampling device is running, the cutting mechanism 20 begins to perform a circular cutting operation on the wall of the sampling hole, and the baffle plate 206 is located at the hole wall near the cutting position by virtue of its connection relationship with the connecting frame assembly 204. When encountering hole walls with different curvatures, the curvature control motor 208 is started according to a preset program or real-time monitoring data. The motor drive end rotates, driving the traction rope connected to it to move. The traction rope pulls the screws at both ends of the baffle plate 206, causing the two ends of the elastic metal plate to be displaced, thereby changing the curvature of the baffle plate 206. In this way, the baffle plate 206 can fit tightly against the wall of the sampling hole. During the cutting process, the broken soil cannot fall due to the obstruction of the baffle plate 206, but can only gather in the space enclosed by the baffle plate 206, the wall of the sampling hole, and the cutting drill mechanism 205, waiting to be collected by the collection mechanism 30.

[0077] The adjustable curvature of the baffle plate 206 ensures that it can accurately adapt to hole walls of various shapes, effectively preventing the broken soil produced by cutting from falling outside the collection area, thereby improving the accuracy and effectiveness of the protection against broken soil and creating good conditions for the pure collection of rare earth samples.

[0078] Since the baffle plate 206 can reliably prevent the broken soil from falling, it avoids the interference of the broken soil on the collection process of the collection mechanism 30 in collecting rare earth samples, so that the collection mechanism 30 can focus on and efficiently collect the samples cut by the cutting mechanism 20, which significantly improves the efficiency and integrity of sample collection and reduces the workload of repeated sampling or cleaning of samples due to the influence of broken soil.

[0079] The connecting frame assembly 204 includes an outer sleeve 2041 and an extension bracket 2042. The extension bracket 2042 is connected to the radial screw mechanism 203. The outer sleeve 2041 is connected to the extension bracket 2042. The baffle plate 206 is passed through the outer sleeve 2041 and is located at the end of the outer sleeve 2041 located on the outside, and the two are relatively flush. The cutting drill bit mechanism 205 is arranged in the outer sleeve 2041 and extends from the end of the outer sleeve 2041.

[0080] The connecting frame assembly 204 optimizes the layout and cooperative working performance of the baffle plate 206 and the cutting drill mechanism 205. The outer sleeve 2041 not only provides a stable protection and support environment for the cutting drill mechanism 205, but also the extension bracket 2042 acts as a bridge for power transmission, transmitting the power of the radial screw mechanism 203 to the outer sleeve 2041. On the one hand, the outer sleeve 2041 provides a passage for the baffle plate 206 to pass through, so that it is located at one end of the outer side and flush with the outer sleeve 2041, ensuring the effective coverage of the baffle plate 206 when blocking the crushed soil; on the other hand, the cutting drill mechanism 205 is accommodated inside, so that it extends from one end of the outer side of the outer sleeve 2041. During the cutting operation, the various components move in coordination under the power drive to achieve stable and efficient cutting and crushed soil blocking operations.

[0081] In some embodiments, the cutting drill bit mechanism 205 includes a central rotating motor 2051, a central rotating seat 2052, an eccentric cutting motor and an eccentric cutting drill 2053. The central rotating seat 2052 is rotatably connected to the outer sleeve 2041. The central rotating motor 2051 is connected to the outer sleeve 2041 and is drivingly connected to the central rotating seat 2052. The eccentric cutting motor is arranged in the central rotating seat 2052 and is drivingly connected to the eccentric cutting drill 2053 through a gear assembly. The eccentric cutting drill 2053 is located at the edge of the central rotating seat 2052.

[0082] The composite drive design of the cutting drill mechanism 205 significantly improves its cutting performance. The eccentric cutting drill 2053 can still use a milling machine drill bit, and its side can also be cut at the same time.

[0083] The central rotating motor 2051 is installed inside the outer sleeve 2041 and is connected to the central rotating seat 2052. After starting, it drives the central rotating seat 2052 to rotate around the central axis in the outer sleeve 2041. The eccentric cutting motor is arranged inside the central rotating seat 2052, and transmits power to the eccentric cutting drill 2053 through the gear assembly, so that it rotates at the edge of the central rotating seat 2052. The combined motion of the two makes the eccentric cutting drill 2053 rotate while accompanied by eccentric motion, forming a unique cutting trajectory, effectively increasing the area of ​​rare earth on the wall of the broken sampling hole.

[0084] In some embodiments, the collection mechanism 30 includes:

[0085] Collecting scraper 301;

[0086] A recovery channel 302, a collection scraper 301 is connected to the outer end of the recovery channel 302, and the collection scraper 301, the baffle plate 206 and the recovery channel 302 form an inlet for the rare earth sample;

[0087] A conveyor belt mechanism 303 is provided at the bottom of the recovery channel 302, which is used to transfer the rare earth sample entering from the inlet to the storage mechanism 40 through the conveyor belt mechanism 303;

[0088] The recovery channel 302 is connected to the connecting frame assembly 204, and the extended position of the collection scraper 301 corresponds to the position of the cutting drill mechanism 205, so that the collection scraper 301 can extend to the inner wall of the sampling groove after being cut by the cutting drill mechanism 205;

[0089] The collection position cleaning drill mechanism is used to pre-cut a collection groove on one side of the cutting mechanism 20 before the cutting mechanism 20 cuts, so that the collection scraper 301 can enter the annular groove cut by the cutting mechanism 20 without hindrance.

[0090] The collection position cleaning drill mechanism includes a three-dimensional slide rail assembly and a cleaning drill device. The three-dimensional slide rail assembly is a slide rail and a sliding device that can be moved in the xyz axis direction. The cleaning drill device is connected to the sliding device and can clean the annular sample groove in advance. Because there is a gap between the collection scraper 301 and the cutting mechanism 20, the collection position cleaning drill mechanism is used to clean this gap to facilitate the cleaning drill feed.

[0091] During the operation of the entire drilling sampling device, when the sampling base 11 reaches the specified depth position and the cutting mechanism 20 is ready to perform a ring cutting operation on the hole wall of the sampling hole, the collecting mechanism 30 starts to work synchronously to ensure that the rare earth sample can be collected in time and completely. In this device, the outer side is the side close to the hole wall.

[0092] The collecting scraper 301 is firmly connected to the outer end of the recovery channel 302, and its extended position corresponds precisely to the position of the cutting drill mechanism 205. When the cutting drill mechanism 205 performs a circular cut on the hole wall of the sampling hole and forms a cut sampling groove on the hole wall of the sampling hole, the collecting scraper 301 can accurately extend to the inner wall of the cut sampling groove by virtue of this corresponding relationship. At this time, the collecting scraper 301, the baffle plate 206 and the recovery channel 302 together form a special rare earth sample inlet structure. The baffle plate 206 blocks the falling of broken soil during the cutting process, so that the rare earth samples produced by the cutting are gathered in the space enclosed by the baffle plate 206, the hole wall of the sampling hole and the cutting drill mechanism 205, and the collecting scraper 301 can smoothly scrape these samples gathered near the inlet into the recovery channel 302.

[0093] The conveyor belt mechanism 303 disposed at the bottom of the recovery channel 302 is then activated. Once the rare earth sample enters the recovery channel 302 through the collection scraper 301, the conveyor belt mechanism 303 uses its own transmission capacity to smoothly transport the sample along the channel, and finally transfers the sample to the storage mechanism 40, realizing the orderly transfer of the sample from the collection position to the storage position.

[0094] There is a certain distance between the collection scraper 301 and the cutting mechanism 20, which may hinder the subsequent collection scraper 301 from entering the annular groove cut by the cutting mechanism 20, affecting the integrity and smoothness of sample collection. Therefore, before the cutting mechanism 20 cuts, the collection position cleaning drill mechanism begins to play a role. The cleaning drill device is similar to the drill structure of the cutting mechanism 20.

[0095] Among them, the three-dimensional slide rail assembly serves as a support and guide structure. It has slide rails and matching sliding devices that can move in three directions of the xyz axis, providing flexible and precise movement capabilities for the cleaning drill device. The cleaning drill device is connected to the sliding device. According to the preset program or the control instructions of the operator, through the precise movement of the three-dimensional slide rail assembly in three directions, it can reach the position of the cutting mechanism 20 side where the ring cutting operation is about to be performed in advance. Then, the cleaning drill device starts and pre-cleans the sample groove for ring cutting, removes obstacles such as excess rock and soil that may prevent the collection scraper 301 from entering the annular groove, and ensures that the collection scraper 301 can subsequently enter the annular groove cut by the cutting mechanism 20 without hindrance, thereby achieving efficient and complete sample collection.

[0096] In some embodiments, the collection mechanism further includes a scraping mechanism, which is configured to synchronously scrape out the rare earth samples remaining on the conveyor belt. Specifically, the scraping mechanism includes a scraping telescopic cylinder and a triangular prism 304, the scraping telescopic cylinder is drivingly connected to the triangular prism 304, and the edge of the triangular prism 304 abuts against the lower part of the exit of the conveyor belt in the conveyor belt mechanism 303, so as to synchronously scrape out the rare earth samples remaining on the conveyor belt.

[0097] The problem of residual samples on the conveyor belt is effectively solved by setting up a scraping mechanism. The combination of the scraping telescopic cylinder and the triangular prism 304 can accurately contact the bottom of the conveyor belt outlet and promptly remove the residual rare earth samples on the conveyor belt. This design avoids the accumulation of residual samples on the conveyor belt and prevents it from interfering with the accuracy of subsequent sampling and collection, ensures the cleanliness of the conveyor belt and the reliability of sample collection, and improves the stability and repeatability of the entire collection system.

[0098] The scraping telescopic cylinder serves as a power source and performs telescopic movements according to a preset control signal. When the conveyor belt needs to be cleaned, the scraping telescopic cylinder extends and drives the triangular prism 304 so that its edges are tightly against the bottom of the conveyor belt outlet. As the conveyor belt continues to run, the remaining rare earth samples are separated from the conveyor belt by the scraping action of the triangular prism 304, achieving the purpose of cleaning. After the cleaning is completed, the scraping telescopic cylinder retracts and waits for the next cleaning instruction. The triangular prism 304 can also be kept in the scraping position at all times. Both can achieve the cleaning function.

[0099] The storage mechanism 40 includes a storage bin 401, a fixed partition 402, a plurality of movable partitions 403, and a partition driving mechanism 404. The storage bin 401 can move along with the collection mechanism 30. The fixed partition 402 and the movable partition 403 are both arranged in the storage bin 401. When the rare earth sample falls into the storage bin 401, the partition driving mechanism 404 drives a movable partition 403 to move, pushing the rare earth sample toward the fixed partition 402, and the two squeeze and compress the rare earth sample. When sampling at the next position, the next movable partition 403 is controlled to move toward the previous movable partition 403 and squeeze and compress it.

[0100] The layered storage and extrusion and compression functions of the storage mechanism 40 facilitate the storage and analysis of rare earth samples. The storage bin 401 and the partition driving mechanism 404 work together to achieve effective separation and sorting of samples at different depths through the cooperation of the fixed partition 402 and the movable partition 403. During the sampling process, as the samples continue to fall in, the partition driving mechanism 404 pushes the movable partition 403 to move in an orderly manner, and squeezes and compresses the samples, which not only reduces the space occupied by the samples, but also improves the compactness of the samples, making them easier to store and transport. At the same time, the layered storage design is conducive to the subsequent independent analysis of samples at different depths, and helps to further study the vertical distribution law of ionic rare earth ores.

[0101] The storage bin 401 is a container for storing samples and can move with the collection mechanism 30 to ensure that the samples can fall into the storage bin accurately. The fixed partition 402 and the movable partition 403 are arranged reasonably in the storage bin 401. When the rare earth sample falls into the storage bin 401, the partition driving mechanism 404 is started to drive a movable partition 403 to move toward the fixed partition 402, squeezing and compressing the sample between the two. When sampling at the next sampling position, the next movable partition 403 continues to move on the basis of the previous movable partition 403 and repeats the squeezing and compression operation, so that samples of different depths are separated and stored in turn to form a layered storage structure.

[0102] The storage bin 401 is a circular ring structure with an entrance at the top. The fixed partition 402 is close to the movable partition 403. An electromagnet structure is provided at the bottom of the movable partition 403. The partition driving mechanism 404 includes a circular track 405 provided at the bottom of the storage bin 401, a moving device moving on the circular track 405, and an electromagnet assembly 406 provided on the moving device. The electromagnet assembly 406 drives the movable partition 403 through the suction force with the electromagnet structure, so that the movable partition 403 moves around in the storage bin 401. Each movable partition 403 forms a separate isolation bin after being circled. An annular magnet 407 is provided on the inner wall of the storage bin 401, which attracts the movable partition 403, so that the movement of the movable partition 403 has a predetermined resistance.

[0103] Among them, the storage bin 401 is connected to the rotating driving motor, which is used to drive the drop bin of the storage bin 401 to rotate with the collecting mechanism 30, so that the rare earth sample always falls into the drop bin, and the force value of the movable partition 403 breaking through the suction of the annular magnet 407 is a, and the driving force of the electromagnet assembly 406 to drive the movable partition 403 through the suction of the electromagnet structure is b, b>a, when the movable partition 403 moves toward the drop bin, the rare earth sample in the drop bin is squeezed and contracted, and an isolation bin is formed, and the squeezing force of the movable partition 403 on the rare earth sample is controlled by setting the driving force b. After completing the action, the moving device controls the electromagnet assembly 406 to continue moving with a moving force exceeding the driving force b, and returns to the bottom of the fixed partition 402, and cuts off the power at the same time. After power off, it moves to the bottom of the next movable partition 403 and then powers on.

[0104] After the rare earth sample is transferred from the collecting mechanism 30 to the entrance above the storage bin 401 via the conveyor mechanism 303 , the storage bin 401 begins to perform its sample storage function.

[0105] In one optional embodiment, an electromagnet structure is provided at the bottom of the movable partition 403, and the electromagnet assembly 406 in the partition driving mechanism 404 is installed on a moving device on a circular track 405 provided at the bottom of the storage bin 401. Both the electromagnet assembly 406 and the moving device can be used as currently mature devices. When it is necessary to separate and store the rare earth samples that fall into the storage bin 401, the electromagnet assembly 406 is energized to generate suction with the electromagnet structure at the bottom of the movable partition 403. Since an annular magnet 407 is provided on the inner wall of the storage bin 401, it is attracted to the movable partition 403, and the movable partition 403 is kept stationary by the resistance of the annular magnet 407 in the initial state. When the suction of the electromagnet assembly 406 is greater than the resistance of the annular magnet 407 to the movable partition 403 (i.e., suction b> resistance a), the movable partition 403 begins to move around on the circular track 405 under the action of the suction. The moving device accurately controls the position of the electromagnet assembly 406 on the circular track 405 according to a preset program and control signal, thereby guiding the moving direction and distance of the movable partition 403.

[0106] When the movable partition 403 moves toward the drop bin of the storage bin 401, the rare earth sample in the drop bin is squeezed and contracted as the movable partition 403 continues to move. By setting the current of the electromagnet assembly 406, the suction force between the electromagnet assembly 406 and the electromagnet structure can be accurately controlled, thereby controlling the squeezing force of the movable partition 403 on the rare earth sample. During the squeezing process, the sample is compressed and tightly arranged between the fixed partition 402 and the movable partition 403, forming a separate isolation bin, thereby realizing the effective separation and storage of samples of different batches or different depths.

[0107] After the sample is squeezed, the moving device controls the electromagnet assembly 406 to continue to move with a moving force that exceeds the suction force b between the electromagnet assembly 406 and the electromagnet structure, so that the movable partition 403 overcomes the suction force and returns to the bottom of the fixed partition 402. At the same time, the electromagnet assembly 406 is powered off, and the movable partition 403 returns to the initial static position under the suction force of the annular magnet 407. When the next sampling is carried out and a new sample needs to be stored, the moving device moves to the bottom of the next movable partition 403, and the electromagnet assembly 406 is powered on again, and the above-mentioned operation process of driving the movable partition 403 to move, squeeze the sample and form an isolation chamber is repeated, and this cycle is repeated to achieve layered storage of multiple samples.

[0108] The storage bin 401 is connected to the rotary drive motor, and during the whole sampling process, the rotary drive motor drives the drop bin of the storage bin 401 to rotate along with the collection mechanism 30 in real time according to the position information of the collection mechanism 30. In this way, it can be ensured that no matter at what angle or position the collection mechanism 30 collects the rare earth sample, the sample can always fall into the drop bin accurately under the action of gravity, thereby improving the accuracy and reliability of sample collection and storage.

[0109] Based on the design of the suction of the electromagnet assembly 406 and the electromagnet structure at the bottom of the movable partition 403 and the resistance of the annular magnet 407, the movement and stopping of the movable partition 403 in the storage bin 401 can be accurately controlled, so that rare earth samples collected at different depths or in different batches can be separated and stored in each isolation bin in turn.

[0110] The driving force on the movable partition 403 is controlled by adjusting the energizing parameters of the electromagnet assembly 406, thereby realizing the precise setting of the sample squeezing force. The appropriate squeezing force can not only effectively reduce the volume of the sample, improve the space utilization rate of the storage bin 401, facilitate the storage and transportation of the sample, but also maintain the structural integrity of the sample to a certain extent.

[0111] The present application also provides a drilling sampling method for ionic rare earth mineral exploration, which uses the aforementioned drilling sampling device for ionic rare earth mineral exploration to perform sampling at different depths in a sampling hole.

[0112] Specifically, the drilling sampling method for ionic rare earth mineral exploration includes the following steps:

[0113] Use drilling equipment to construct sampling holes in the target exploration area of ​​ionic rare earth minerals;

[0114] Above the sampling hole, the lifting rail 10 is installed and positioned by using a positioning frame through two fixed points that are collinear in the upper and lower directions, so that the lifting rail 10 is stable and extends vertically to the bottom of the sampling hole;

[0115] According to the preset sampling depth information, the lifting driver of the sampling base 11 is started, so that the sampling base 11 is smoothly lifted and moved along the lifting track 10 to the specified sampling depth position;

[0116] When the sampling base 11 reaches the designated depth position, the cutting mechanism 20 is started to perform a ring cutting operation on the hole wall of the sampling hole at that position, so as to completely separate the rare earth sample from the hole wall of the sampling hole;

[0117] The collecting mechanism 30 operates synchronously with the cutting mechanism 20, closely follows the cutting process, and collects the rare earth samples cut by the cutting mechanism 20. The collecting port of the collecting mechanism 30 corresponds to the cutting position, and can capture the cut samples.

[0118] The rare earth samples collected by the collecting mechanism 30 are directly transferred to the storage mechanism 40;

[0119] The storage mechanism 40 stores the samples in layers according to the sampling depth, and stores the samples collected at different depths in different storage areas;

[0120] After completing the operation at one sampling location, repeat the above steps according to the sampling plan and continue sampling operations at other specified depths or locations until the entire sampling task is completed.

[0121] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above are only specific implementation methods of the present application and are not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
