Description

Technical Field

[0001] This invention relates to the field of sampling equipment technology, and more specifically, to an exploration device for automated sampling and analysis of rare earth ores. Background Technology

[0002] In the exploration and development of rare earth mineral resources, accurate collection and compositional analysis of ore samples are crucial for assessing deposit grade and guiding mining strategies. Because rare earth ores often exhibit complex layered structures (such as a skin layer, oxide layer, sulfide layer, metal-enriched layer, and core layer), and their elemental distribution varies significantly from the surface to the interior, extremely high requirements are placed on the depth adaptability of sampling equipment, sample integrity, and stratigraphic fidelity. Currently, the industry commonly employs a sampling system consisting of drilling rigs, crushing and screening devices, and elemental analyzers. This system uses physical drilling for core extraction, crushing and preparing samples for testing to obtain data on the internal elemental composition of the ore.

[0003] A search revealed that the invention with authorization announcement number CN116754285B discloses a soil sampling device for improving planting soil, including a sampling mechanism and a core extractor. The sampling mechanism is used to insert into the soil to obtain soil samples. The core extractor is made of a different material than the sampling mechanism and is used to extract the target soil sample from the sampling mechanism. The target soil sample does not come into contact with the sampling mechanism. The overall structure of this sampling device still follows the traditional "long rod series + manual tamping" operation mode, which has obvious limitations when facing the sampling needs of rare earth ores or deep hard strata.

[0004] Firstly, to achieve deep drilling, physical sampling rods must be continuously attached, resulting in a long longitudinal dimension, significantly increased weight, and poor portability of the entire machine. Secondly, in complex terrain or high-density rock debris layers, the exploration and retrieval process is extremely time-consuming and labor-intensive, cumbersome to operate, highly dependent on manpower, and has high labor intensity and low work efficiency. Thirdly, after the sampling tube brings soil samples out of the soil layer, it needs to be manually knocked or pried to remove them, which is not only inefficient but also prone to cross-contamination due to residues from different samples. Therefore, to overcome the shortcomings of existing soil sample collection technologies, we propose an exploration device for automated sampling and analysis of rare earth ores. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an exploration device for automated sampling and analysis of rare earth ores.

[0006] The technical solution is as follows: An exploration device for automated sampling and analysis of rare earth ores includes a base plate and a housing. The housing is fixedly mounted on the base plate, and a handle for easy carrying is provided on the top of the housing. A mounting frame is fixedly mounted on the base plate inside the housing. The device also includes an outer shell fixedly connected to the top of the housing. A winding wheel is rotatably mounted inside the outer shell, and a chain rod is wound around the winding wheel. A guide frame is fixedly connected to the middle of the mounting frame. The guide frame guides the chain rod and is connected to the outer wall of the outer shell. A sampling cylinder is installed at the end of the chain rod. An opening adapted to the sampling cylinder is provided on the base plate. At least two sets of driving components are provided on the guide frame, and the driving components drive the chain rod to move along the guide frame. The sampling cylinder moves inwards, cooperating with the winding reel to unwind the chain rod, allowing it to move and collect samples. The chain rod is composed of alternating links and universal joints, both of which are hollow structures. A pin is slidably connected to one end of each link, used to rigidly lock adjacent links and universal joints. A piston cylinder is fixedly installed inside each link, with a guide tube connected to the end of the piston cylinder facing the pin. The guide tube slides through the pin in a sealed manner. A spring is installed between the piston cylinder and the pin. An electromagnet is fixedly installed on the inner wall of the piston cylinder away from the guide tube. A piston block is slidably installed inside the piston cylinder, and a magnet is fixedly installed on the piston block. The magnet and the electromagnet, when energized, have the same magnetic poles.

[0007] Optionally, a motor is fixedly mounted on the mounting bracket. The output shaft of the motor is connected to the shaft of the reel via a drive belt. The motor drives the reel to rotate in both directions via the drive belt, enabling the reel to efficiently unwind the chain rod.

[0008] Optionally, the driving component includes a bearing seat fixedly installed in the guide frame, two driving wheels symmetrically rotatably mounted on the bearing seat, the driving wheels being used to drive the chain rod to move, and a second motor fixedly installed on the outer wall of the guide frame, the output shaft of the second motor being connected to the rotating shaft of the corresponding driving wheel.

[0009] Optionally, the sampling tube consists of a mounting shell, a connecting frame, and a tube body. The mounting shell is fixedly mounted on a section of the chain rod at the end of the connecting frame. A tube body for sampling is rotatably connected to the mounting shell, and the sampling port of the tube body is serrated.

[0010] Optionally, a motor three is fixedly mounted on the mounting shell, a gear is fixedly connected to the output shaft of the motor three, and a gear ring is fixedly provided on the top of the cylinder, with the gear and gear ring meshing with each other.

[0011] Optionally, two sensors are vertically spaced on the guide frame. Each sensor has a built-in controller for controlling the on / off state of the electromagnet. The sensor is used to sense the motion state of the electromagnet.

[0012] Optionally, multiple airbags are embedded circumferentially in the inner wall of the cylinder. The airbags are constructed with special materials and are thickened and wear-resistant. The airbags are initially attached to the inner wall of the cylinder. An inflation pipe is provided at the top of the cylinder. The inflation pipe is used to connect to an external air supply device. The inflation pipe is connected to each airbag through multiple air inlet pipes.

[0013] Optionally, an ejector is provided at the top of the inner wall of the cylinder. The ejector is used to assist in ejecting the sampled soil from the cylinder. Each airbag is connected to the ejector through an air outlet pipe. The ejector includes a pressure valve and a top block. The pressure valve is fixedly installed at the top of the inner wall of the cylinder. The lower part of the pressure valve is open. The air outlet pipe is connected to the top of the pressure valve. A top block is slidably and sealed on the lower outer side of the pressure valve. The ejector surface of the top block is flush with the top of the inner wall of the cylinder. A spring is provided between the cylinder and the top block. The top block has multiple air outlets circumferentially. A sealing ring is fixedly installed inside the pressure valve. A valve plug is slidably installed inside the pressure valve through a support block. A spring is provided between the support block and the valve plug. The valve plug blocks the opening of the sealing ring.

[0014] Optionally, a sample outlet is provided on one side of the housing, and a guide plate is fixedly connected to the bottom plate near the outlet of the housing. The guide plate is located directly below the sampling cylinder and has a corresponding opening. A discharge plate is slidably connected to the guide plate. An electric lead screw is mounted on the bottom plate, and the electric lead screw and the discharge plate are threaded together. A hopper is provided on one side of the discharge plate, and a bracket is fixedly connected to the other side of the discharge plate. A lifting frame is slidably installed on the bracket, and a cleaning brush is provided inside the lifting frame. The cleaning brush is used to clean the sampling cylinder. A cylinder is hinged to the discharge plate, and the piston rod of the cylinder is connected to the lifting frame.

[0015] The beneficial effects of this invention are: 1. This invention utilizes an electromagnet, piston, and hydraulic linkage structure to automatically trigger the extension of the pin during the sampling descent process, achieving a rigid connection between adjacent rod sections and ensuring stable drilling of the sampling cylinder; after sampling is completed, the electromagnet is de-energized, the pin automatically retracts, and the chain rod returns to flexibility, facilitating rapid winding and balancing rigid sampling with convenient storage.

[0016] 2. The chain rod of the present invention is composed of multiple sections of rod connected in series with universal joints. It can be extended or retracted according to actual exploration needs. The chain rod is automatically lowered and retrieved by the motor-driven reel and the drive component in the guide frame. It is used in conjunction with the sampling cylinder for automatic drilling and sampling, reducing manual intervention and solving the problem of time-consuming and labor-intensive traditional manual sampling.

[0017] 3. This invention utilizes a structure that integrates a thickened, wear-resistant airbag with a top ejector inside the cylinder. After inflation, the airbag expands, separating the soil from the cylinder wall. Simultaneously, high-pressure gas triggers the top block to push down and jets air to purge, enabling the sampled soil to be efficiently extracted. This solves the problems of easily damaged equipment, sample contamination, or loss associated with traditional impact sampling. Attached Figure Description

Detailed Implementation

[0032] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0033] An automated sampling and analysis exploration device for rare earth ores, referring to Figures 1-6As shown, the device includes a base plate 1 and a housing 2. The housing 2 is fixedly mounted on the base plate 1, and a handle 21 for easy carrying is provided on the top of the housing 2. A mounting frame 3 is fixedly mounted on the base plate 1 inside the housing 2. It also includes an outer shell 4 fixedly connected to the top of the housing 2. A winding wheel 5 is rotatably mounted inside the outer shell 4, and a chain rod 6 is wound around the winding wheel 5. A guide frame 41 is fixedly connected to the middle of the mounting frame 3. The guide frame 41 guides the chain rod 6 and is connected to the outer wall of the outer shell 4. A sampling cylinder 8 is installed at the end of the chain rod 6. An opening for the sampling cylinder 8 is provided on the base plate 1. Two sets of driving components 9 are provided on the guide frame 41. The driving components 9 drive the chain rod 6 to move within the guide frame 41, cooperating with the winding wheel 5 to unwind the chain rod 6, allowing the sampling cylinder 8 to move and collect samples. The chain rod 6 is constructed by alternating series connection of a section rod 61 and a universal joint 62. The joint rod 61 and universal joint 62 are both hollow structures. One end of the joint rod 61 is slidably connected to a pin 611, which can be inserted into the joint rod 61 and universal joint 62 to rigidly lock the adjacent joint rod 61 and universal joint 62. A piston cylinder 612 is fixedly installed inside the joint rod 61. The end of the piston cylinder 612 facing the pin 611 is connected to a conduit 613. The piston cylinder 612 and the conduit 613 are filled with hydraulic oil. The conduit 613 is sealed and slides through the pin 611. A spring 614 is installed between the piston cylinder 612 and the pin 611. An electromagnet 7 is fixedly installed on the inner wall of the piston cylinder 612 away from the conduit 613. A piston block 71 is slidably installed inside the piston cylinder 612. A magnet 72 is fixedly installed on the piston block 71. The magnet 72 and the electromagnet 7 have the same magnetic poles when energized.

[0034] Reference Figure 2 As shown, a motor 51 is fixedly mounted on the mounting bracket 3. The output shaft of the motor 51 is connected to the rotating shaft of the reel 5 via a drive belt 52. The motor 51 drives the reel 5 to rotate in both directions via the drive belt 52, so that the reel 5 can efficiently unwind the chain rod 6.

[0035] Reference Figure 3 and Figure 7 As shown, the driving component 9 includes a bearing seat 91 fixedly installed in the guide frame 41. Two driving wheels 92 are symmetrically rotatably installed on the bearing seat 91. The driving wheels 92 are used to drive the chain rod 6 to move. A second motor 93 is fixedly installed on the outer wall of the guide frame 41. The output shaft of the second motor 93 is connected to the rotating shaft of the corresponding driving wheel 92.

[0036] Reference Figure 3 and Figure 4 As shown, the sampling cylinder 8 consists of a mounting shell 81, a connecting frame 82, and a cylinder 83. The mounting shell 81 is fixedly mounted on a section of the rod 61 at the end of the chain rod 6 via the connecting frame 82. The cylinder 83 for sampling is rotatably connected to the mounting shell 81, and the sampling port of the cylinder 83 is serrated.

[0037] Reference Figure 3 and Figure 7 As shown, two sensors 10 are vertically spaced on the guide frame 41. Each sensor 10 has a built-in controller that controls the on / off state of the electromagnet 7. The sensor 10 is used to sense the movement state of the electromagnet 7. When the electromagnet 7 in the link 61 passes through the two sensors 10 from top to bottom, the sensor 10 can determine that the link 6 is in a downward sampling state, and thus controls the electromagnet 7 currently passing through the link 61 to be energized, so that the pin 611 is inserted into the lower universal joint 62 and the link 61, thereby achieving rigid fixation between the links 61 and preventing radial displacement between adjacent links 61 and universal joint 62. When the electromagnet 7 in the link 61 passes through the two sensors 10 from bottom to top, the sensor 10 can determine that the link 6 is in an upward winding state, and thus controls the electromagnet 7 currently passing through the link 61 to be de-energized, so that the pin 611 retracts from the lower universal joint 62 and the link 61, automatically releasing the rigid fixation between the links 61, so that it can be subsequently wound and stored by the winding wheel 5.

[0038] Before using the equipment for exploration and sampling, the operator first places and secures the base plate 1 at the target sampling location. Then, the equipment is started to begin sampling. Motor 1 51 begins operation, driving the shaft of the reel 5 to rotate via the drive belt 52. This causes the chain rod 6 on the reel 5 to unwind and enter the guide frame 41. Simultaneously, multiple sets of drive components 9 on the guide frame 41 also start synchronously. Motor 2 93 in each set of drive components 9 drives the corresponding drive wheel 92 to rotate, thereby actively clamping and driving the chain rod 6 to descend stably within the guide frame 41. At the same time, the chain rod 6... The locking mechanism is activated: When the piston cylinder 612 and electromagnet 7 inside the link 61 pass through the two sensors 10 vertically spaced on the guide frame 41 from top to bottom, the sensors 10 can determine that the link 6 is in a downward sampling state based on the sequence of sensing. The above sensing and judgment method is existing technology and can be executed by a through-beam photoelectric sensor, a programmable logic controller (PLC), or other controllers, which will not be elaborated here. At this time, the controller built into the sensor 10 immediately sends an energizing command to the electromagnet 7 inside the currently passing link 61. After being energized, the electromagnet 7... The magnetism is generated. Since the magnetic poles of electromagnet 7 are the same as those of magnet 72, a repulsive force will be generated between electromagnet 7 and magnet 72, pushing piston block 71 to slide closer to guide tube 613 inside piston cylinder 612, compressing the hydraulic oil inside piston cylinder 612. The compressed hydraulic oil flows into the inside of pin 611 through guide tube 613. The hydraulic pressure generated at this time overcomes the elastic force of spring 614 between piston cylinder 612 and pin 611, and pushes pin 611 out from the end of joint rod 61, and firmly inserts it into the corresponding hole of adjacent universal joint 62 and lower joint rod 61. The process occurs segment by segment as the chain rod 6 descends, transforming the originally flexible chain rod 6, composed of alternating links 61 and universal joints 62, into a rigid drilling rod with sufficient vertical strength, rigidly locked by pins 611. Combined with the unwinding of the reel 5 and the clamping drive of the drive wheel 92, a stable downward pushing force is generated on the chain rod 6, thereby ensuring that the sampling tube 8 on the lowest link 61 of the chain rod 6 can be effectively inserted into and penetrate the soil layer. Thus, by controlling the unwinding of the reel 5 and the length of the chain rod 6 driven by the drive component 9, the sampling tube 8 can be flexibly adjusted to achieve the required sampling depth.

[0039] Reference Figure 4 and Figure 8 As shown, a motor 11 is fixedly mounted on the mounting shell 81, and a gear 111 is fixedly connected to the output shaft of the motor 11. A gear ring 112 is fixedly installed on the top of the cylinder 83. The gear 111 and the gear ring 112 mesh with each other. The motor 11 drives the gear ring 112 through the meshing of the gear 111, so that the cylinder 83 on the mounting shell 81 can rotate and sample in the soil layer.

[0040] Reference Figure 9 and Figure 10As shown, multiple airbags 12 are embedded circumferentially within the inner wall of the cylinder 83. The airbags 12 are made of highly elastic and wear-resistant polyurethane (TPU) composite material, with a thickened surface and an internal fiber reinforcement layer to improve tear resistance. The airbags 12 initially fit the inner wall of the cylinder 83. An inflation pipe 121 is provided at the top of the cylinder 83. The inflation pipe 121 is used to connect to an external air supply device. The inflation pipe 121 is connected to each airbag 12 through multiple air inlet pipes 122.

[0041] Reference Figures 9-11 As shown, an ejector 13 is provided at the top of the inner wall of the cylinder 83. The ejector 13 is used to assist in ejecting the sampled soil inside the cylinder 83. Each airbag 12 is connected to the ejector 13 through an air outlet pipe 123. The ejector 13 includes a pressure valve 131 and a top block 132. The pressure valve 131 is fixedly installed at the top of the inner wall of the cylinder 83. The lower part of the pressure valve 131 is open, and the air outlet pipe 123 is connected to the top of the pressure valve 131. The lower outer side of the pressure valve 131 is sealed and slidable. A top block 132 is provided, with its protruding surface flush with the top of the inner wall of the cylinder 83. A spring 133 is provided between the cylinder 83 and the top block 132. The top block 132 has multiple air outlets circumferentially. A sealing ring 134 is fixedly provided inside the air pressure valve 131. A valve plug 137 is slidably installed inside the air pressure valve 131 through a support block 135. A spring 136 is provided between the support block 135 and the valve plug 137. The valve plug 137 can block the opening of the sealing ring 134.

[0042] When the chain rod 6 extends to the predetermined depth to begin sampling, motor 3 11 is activated. Motor 3 11 drives the gear ring 112 fixed to the top of the cylinder 83 via gear 111, causing the cylinder 83 to rotate relative to the mounting shell 81 and connecting frame 82. The serrated sampling port at the lower end of the cylinder 83 rotates and cuts in the soil layer. As the chain rod 6 continues to descend, rare earth ore samples are collected and stored inside the cylinder 83. After sampling is completed, the chain rod 6 begins to ascend and recover under the coordinated action of the drive component 9 and the reel 5. When it is necessary to remove the soil sample from the cylinder 83, the operator connects the air inlet pipe 121 at the top of the cylinder 83 to an external air supply device, allowing high-pressure air to flow. The gas is supplied through the inflation pipe 121 and multiple air inlet pipes 122 to multiple air bladders 12 circumferentially spaced within the inner wall of the cylinder 83. These air bladders 12, constructed with special materials and thickened for wear resistance, expand under air pressure. Initially, the air bladders 12, which are attached to the inner wall of the cylinder 83, bulge outwards. Simultaneously, some gas in each air bladder 12 flows to the top of the pressure valve 131 through its respective connected outlet pipe 123. However, because the valve plug 137 in the pressure valve 131 is blocked at the opening of the fixed sealing ring 134 by the action of the spring 136, the gas is temporarily blocked, allowing the air bladder 12 to continue expanding to its maximum state (the expansion amount is controlled between 0.5-1.0). (mm), at this time, the airbag 12 pushes out an annular gap between the collected soil sample and the inner wall of the cylinder 83, and only disturbs the surface layer of soil attached to the inner wall of the cylinder 83, breaking the adhesion between the surface layer of soil and the inner wall of the cylinder 83, without significantly compressing the sample soil. When the air pressure in the airbag 12 continues to rise and exceeds the preset blocking force of the spring 136 in the pressure valve 131 on the valve plug 137, the high-pressure gas instantly breaks through the valve plug 137 and sprays out at high speed from the top of the pressure valve 131. This airflow acts on the top block on the lower outer side of the pressure valve 131. On 132, the top block 132 is pushed downwards against the elastic force of the spring 133. At this time, the top surface of the top block 132 is no longer flush with the top of the inner wall of the cylinder 83, but protrudes downwards, mechanically pushing the soil sample that has been loosened by the expansion of the air bladder 12. At the same time, some high-pressure gas is ejected from the multiple air outlets opened around the top block 132, producing an auxiliary "air blowing" effect on the soil sample. The combined effect of mechanical pushing and airflow flushing allows the soil sample to be discharged smoothly and completely from the cylinder 83, effectively solving the problem of inefficiency in manually tapping the cylinder wall for sampling.

[0043] Reference Figure 1 , Figure 12 and Figure 13As shown, a sample outlet is provided on one side of the housing 2. A guide plate 14 is fixedly connected to the bottom plate 1 near the outlet of the housing 2. The guide plate 14 is located directly below the sampling cylinder 8 and has a corresponding opening. This opening is the sampling channel for the sampling cylinder 8 to move upward and downward. A discharge plate 141 is slidably connected to the guide plate 14. An electric screw 142 is mounted on the bottom plate 1. The electric screw 142 and the discharge plate 141 are threaded together. A hopper is provided on one side of the discharge plate 141. A bracket 143 is fixedly connected to the other side of the discharge plate 141. A lifting frame 144 is slidably installed on the bracket 143. A cleaning brush 145 is provided inside the lifting frame 144. The cleaning brush 145 is used to clean the sampling cylinder 8. A cylinder 146 is hinged to the discharge plate 141. The piston rod of the cylinder 146 is connected to the lifting frame 144.

[0044] Before the soil sample is removed from the sampling cylinder 8, the electric screw 142 starts working, driving the discharge plate 141, which is engaged with the internal thread, to slide on the guide plate 14. This causes the hopper on one side of the discharge plate 141 to move precisely below the sampling cylinder 8, thus catching the sample soil falling from the sampling cylinder 8. After the sample soil is collected, the electric screw 142 drives the discharge plate 141 to move laterally again, so that the lifting frame 144 on the bracket 143 on the other side of the discharge plate 141 and its internal cleaning brush 145 are accurately aligned with the cylinder 83 of the suspended sampling cylinder 8. Then, the pneumatic system is activated. Cylinder 146 pushes the lifting frame 144, carrying the cleaning brush 145, to slide upward along the bracket 143 until the cleaning brush 145 is raised and extends into the cylinder 83. At this time, the motor 11 on the mounting shell 81 starts again, driving the cylinder 83 to rotate at a constant speed. The inner wall of the high-speed rotating cylinder 83 moves relative to the stationary cleaning brush 145, and the soil debris remaining on the wall of the cylinder 83 is effectively swept off. The swept debris is carried out of the cylinder 83 with the movement of the cleaning brush 145, and the swept debris finally falls into the lifting frame 144 for collection.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
