Description

Technical Field

[0001] This utility model is a sampling device for geological prospecting and exploration, belonging to the field of geological exploration sampling. Background Technology

[0002] In the field of geological prospecting, accurate collection of soil and ore samples is a core prerequisite for subsequent resource reserve assessment and mineral composition analysis. The quality of sampling directly determines the reliability of exploration data and the efficiency of exploration work. As mineral resource exploration advances into deeper strata and areas with complex geological conditions, higher demands are placed on the professionalism, adaptability, and ease of operation of sampling devices. Especially in the differentiated collection of soil and ore samples, existing technologies still have significant shortcomings and cannot meet the actual needs of efficient and accurate exploration. Currently, most mainstream geological sampling devices adopt a single sampling structure design, or can only collect soil samples, or can only collect ore samples.

[0003] In actual exploration operations, workers often need to collect soil samples at the same exploration point to analyze the stratigraphic distribution pattern, and then collect ore samples to determine the mineral occurrence state. This requires frequent replacement of sampling tubes—that is, first disassembling the soil sampling tube, then installing the ore sampling tube, and then reversing the operation to restore the soil sampling function after completing the ore sampling. This process not only requires machine shutdown, but also requires the use of special tools to complete the disassembly and assembly of components. This not only consumes a lot of time and reduces the efficiency of exploration operations, but also easily leads to a decrease in the sealing of the connection between the sampling tube and the device due to operational errors during the disassembly and assembly process. More importantly, traditional ore sampling tubes are very prone to mixing with the upper soil layer when collecting ore samples. The final result is not a pure ore column, but a mixed sample mixed with soil, which increases the complexity and time cost of subsequent work. Therefore, it is necessary to design a sampling device for geological prospecting and exploration. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sampling device for geological prospecting and exploration, so as to solve the problems mentioned in the background technology.

[0011] Furthermore, the rotary drive assembly includes an adjusting motor and a rotating sleeve, with the adjusting motor fixed to the top of the support plate and the rotating sleeve located at the center of the bottom of the support plate. A rotating disk with a shape matching the internal shape of the rotating sleeve is located at the center of the top of the H-shaped mounting bracket, and the output end of the adjusting motor passes through the support plate and is connected to the rotating disk.

[0012] Furthermore, the power output assembly includes a small hydraulic telescopic rod, a rotary motor, and a plug rod. A small hydraulic telescopic rod is fixed at the center of the top of the boss, and a rotary motor is installed in the receiving groove. The output end of the small hydraulic telescopic rod is connected to the top of the housing of the rotary motor. A plug rod is fixed at the output end of the rotary motor, and the cross-section of the plug rod is a rectangular design with rounded corners. Mounting seats are hinged at both ends inside the H-shaped mounting bracket, and servo motors are fixed on the H-shaped mounting brackets on one side of the two mounting seats. The output end of the servo motor is connected to the side wall of the corresponding mounting seat. A connecting assembly is installed at the center of the mounting seat, and the connecting assembly includes a rotating part, a threaded sleeve, and a venting hose that are rotatably connected to the mounting seat. The longitudinal section of the rotating part is designed in the shape of an "I". A slot that matches the shape of the plug rod is opened at the center of the top of the rotating part. A threaded sleeve is integrally connected to the bottom of the rotating part, and a venting hose is connected to one side of the threaded sleeve. The two exhaust ports of the three-way valve are respectively connected to the two threaded sleeves through two venting hoses.

[0013] Furthermore, the soil sampling assembly includes a first threaded head, a soil-breaking blade, a first piston plate, a first air hole, and a soil sampling tube.

A retaining structure is provided at the bottom of the ore extraction pipe, and the retaining structure includes a retaining plate, a hinge seat, and a return spring. Six slots are equally spaced on the ore extraction pipe wall above the alloy ring cutter, and a hinge seat is provided at the bottom of each of the six slots. A retaining plate is hinged to the hinge seat, and the retaining plate is a one-sixth fan-shaped design with a diameter consistent with the inner diameter of the ore extraction pipe. A return spring is connected between the bottom of the slot and the retaining plate.

[0015] The beneficial effects of this utility model are: 1. This device solves this problem through an integrated design. The H-shaped mounting frame of the sampling mechanism is pre-installed with soil sampling and ore sampling components at both ends. With the linkage between the rotary drive component and the rotary disk, the target sampling component can be switched to the position directly below the power output component simply by adjusting the motor to drive the rotary disk to rotate the H-shaped mounting frame. There is no need to stop the machine to disassemble the sampling tube. The entire switching process does not require special tools, greatly shortening the operation time and effectively avoiding the time wasted by traditional disassembly and assembly, significantly improving the efficiency of exploration operations. At the same time, by reducing the number of times the sampling tube and the device are disassembled and assembled, the risk of "operational error damaging the connection seal" is reduced from the root, ensuring the stability of the sampling process.

[0016] 2. A soil retaining structure is installed at the bottom of the ore extraction pipe. Under normal conditions, six fan-shaped soil retaining plates remain horizontal under the action of return springs, forming a "soil interception barrier." When the ore extraction pipe drills down through the upper soil layer, loose soil particles are blocked by the soil retaining plates and discharged from the slots in the pipe wall, preventing them from entering the ore extraction pipe. When it comes into contact with harder ore, the ore will push the soil retaining plates to rotate around the hinge seat to a vertical position, ensuring that the ore can form a complete cylindrical sample to enter the ore extraction pipe. The final ore sample obtained is free of soil contamination and does not require subsequent manual sorting, greatly reducing the complexity and time cost of subsequent work. The guide sleeve inserted into the bottom plate opening has ball bearings embedded in the inner wall of its plug ring, which can accurately guide the drilling path of the soil extraction pipe or the ore extraction pipe, preventing the sampling pipe from scraping the surrounding soil due to deviation.

[0017] 3. Traditional "mechanical jacking unloading" methods can easily lead to ore sample breakage. This device uses pneumatic-assisted unloading: an air pump supplies air to the soil extraction pipe or ore extraction pipe through a three-way valve and air delivery hose, pushing the first or second piston plate to move and assist in sample removal. Furthermore, the retaining structure design of the ore extraction pipe can prevent "excessive air pressure from causing the sample to pop out and break" - when the second piston plate moves to the slotted position, the air pressure will leak from the slot, the piston plate will stop moving forward, and the staff can manually and steadily pull out the ore core to ensure sample integrity.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 7 This utility model provides a technical solution: a sampling device for geological prospecting and exploration, including a base plate 1, a guide frame 4 installed on the top of the base plate 1, and two support mechanisms 2 symmetrically arranged on both sides of the base plate 1. An adjustment mechanism 5 is arranged inside the guide frame 4. The adjustment mechanism 5 includes a lifting carrier 501, a rotary drive assembly 504, and a power output assembly 13. The lifting carrier 501 is vertically connected to the guide frame 4, and the power output assembly 13 is arranged at the center of the lifting carrier 501. A support plate 5013 protrudes outward from the center of one end of the lifting carrier 501, and the rotary drive assembly 504 is arranged on the support plate 5013. The sampling mechanism 8 includes an H-shaped mounting frame 801, a soil sampling assembly 10, and a mineral sampling assembly 11. At the top center of the 01, a rotary disk 805 is connected to the output end of the rotary drive assembly 504. The two ends of the H-shaped mounting frame 801 are respectively equipped with a soil sampling assembly 10 and a mineral sampling assembly 11. An air pump 6 is located on one side of the top of the lifting platform 501. A three-way valve 601 is provided at the bottom air outlet of the air pump 6. Through the integrated base plate 1, adjustment mechanism 5, sampling mechanism 8 and air pump 6, the functions of sampling, power drive and air pressure assistance are coordinated. The H-shaped mounting frame 801 of the sampling mechanism 8 integrates the soil sampling assembly 10 and the mineral sampling assembly 11. With the adjustment motor 5041 of the rotary drive assembly 504 and the rotary disk 805, the sampling type can be quickly switched without the need to disassemble the sampling components separately, which greatly improves the exploration efficiency.

[0021] Please see Figure 1 and Figure 3 An opening 101 is provided at the center of the base plate 1, and two wheels 9 are provided at both ends of the bottom of the base plate 1. The opening 101 is located directly below the power output component 13, and a guide sleeve 3 is inserted into the opening 101. The wheels 9 at the bottom of the base plate 1 facilitate the flexible movement of the device at the exploration site and adapt to the rapid switching of different exploration points. The opening 101 is precisely aligned with the power output component 13 to ensure that the soil sampling pipe 1005 of the soil sampling component 10 or the ore sampling pipe 1106 of the ore sampling component 11 drills vertically. The guide sleeve 3 in the opening 101 further improves the stability of the sampling path and avoids sample deviation caused by sampling offset.

[0022] Please see Figure 3The guide sleeve 3 includes an anti-detachment ring 301, a plug ring 302, and ball bearings 303. The outer diameter of the plug ring 302 matches the inner diameter of the opening 101, and the top of the plug ring 302 is integrally connected to an anti-detachment ring 301 with a diameter larger than the inner diameter of the opening 101. Ball bearings 303 are evenly embedded in the inner sidewall of the plug ring 302, and the inner diameter of the plug ring 302 matches the outer diameter of the soil sampling pipe 1005 and the ore sampling pipe 1106 of the soil sampling assembly 10 and the ore sampling assembly 11. The anti-detachment ring 301 prevents the guide sleeve 3 from falling off the opening 101, ensuring structural stability; the ball bearings 303 on the inner wall of the plug ring 302 reduce the friction between the soil sampling pipe 1005 or the mining pipe 1106 and the guide sleeve 3, reducing the drilling resistance of the sampling pipe, while avoiding pipe wall wear and extending the service life of the soil sampling pipe 1005 and the mining pipe 1106; the plug ring 302 is precisely matched with the sampling pipe, which can block external soil particles from entering the sampling channel and ensure sample purity.

[0023] Please see Figure 1 and Figure 3 The support mechanism 2 includes a support plate 201, an adjusting screw 202, and a guide rod 203. The support plates 201 are symmetrically arranged on both sides of the bottom of the base plate 1, and the adjusting screw 202 is rotatably connected to the center of the top of the support plate 201. The guide rods 203 are fixed at both ends of the top of the support plate 201, and the top of the guide rods 203 penetrates through the base plate 1. The adjusting screw 202 is threadedly connected to the base plate 1. By rotating the adjusting screw 202, the height of the support plate 201 can be flexibly adjusted to adapt to rugged and uneven exploration ground, ensuring that the device remains horizontal and stable during sampling, and avoiding sampling depth deviation or sample damage due to device tilt. The guide rod 203 at the top of the support plate 201 can limit the movement direction of the support plate 201, prevent the support plate 201 from shifting during the adjustment process, and improve the adjustment accuracy.

[0024] Please see Figure 1 and Figure 3 The guide frame 4 includes two vertical frames 401, two guide columns 402, and a support plate 403. The lifting platform 501 is positioned between the two vertical frames 401. The two vertical frames 401 are symmetrically arranged on both sides of the top of the base plate 1. The longitudinal section of each vertical frame 401 is U-shaped. A guide column 402 is vertically positioned at the center of each vertical frame 401. The support plate 403 is integrally connected to the top of one of the vertical frames 401 on the side furthest from the lifting platform 501. The top of the carrier plate 403 is fixed with a hydraulic cylinder 7 by bolts. The "U"-shaped vertical frame 401 of the guide frame 4 provides a stable installation and movement space for the lifting carrier 501. The guide column 402 inside the vertical frame 401 can guide the lifting carrier 501 to rise and fall vertically, avoid deviation during the lifting process, and ensure the verticality of the soil sampling pipe 1005 / mineral sampling pipe 1106 when drilling. The carrier plate 403 provides a stable support for the hydraulic cylinder 7, ensuring that the hydraulic cylinder 7 can stably output driving force to meet the sampling needs of strata at different depths.

[0025] Please see Figure 1 and Figure 2 A raised boss 5012 is provided at the center of the top of the lifting platform 501, and a receiving groove 5011 is provided at the bottom of the boss 5012. Limiting sliders 502 are symmetrically arranged on both sides of the lifting platform 501, and each limiting slider 502 has a guide groove 5021 at its center with an inner diameter that matches the outer diameter of the guide post 402. The cross-section of the limiting slider 502 is I-shaped, and the shape of the limiting slider 502 matches the internal shape of the vertical frame 401. A connecting plate 503 is integrally connected to the side of one of the limiting sliders 502 away from the lifting platform 501, and the bottom of the hydraulic cylinder 7... The output end is fixedly connected to the bearing plate 403 and the connecting plate 503 through the bearing plate 403. The "I"-shaped limiting sliders 502 on both sides of the lifting seat 501 are precisely matched with the vertical frame 401 and the guide column 402, which greatly improves the stability and smoothness of the lifting seat 501 and avoids jamming. The receiving groove 5011 inside the boss 5012 provides a hidden installation space for the rotary motor 1302 of the power output component 13, reducing the damage to the rotary motor 1302 caused by external collisions. The connecting plate 503 on one side of the limiting slider 502 ensures that the driving force of the hydraulic cylinder 7 can be stably transmitted to the lifting seat 501, so as to achieve precise control of the sampling depth.

[0026] Please see Figure 2 The rotary drive assembly 504 includes an adjusting motor 5041 and a rotating sleeve 5042. The adjusting motor 5041 is fixed to the top of the support plate 5013, and the rotating sleeve 5042 is located at the center of the bottom of the support plate 5013. A rotating disk 805 with a shape matching the internal shape of the rotating sleeve 5042 is located at the center of the top of the H-shaped mounting frame 801. The output end of the adjusting motor 5041 passes through the support plate 5013 and is connected to the rotating disk 805. The adjusting motor 5041 of the rotary drive assembly 504 drives the rotating disk 805 on the top of the H-shaped mounting frame 801, causing the H-shaped mounting frame 801 to rotate. This allows for quick switching of the soil sampling component 10 or the ore sampling component 11 to the working position without the need for manual disassembly and assembly of the sampling components. The operation is convenient and the switching efficiency is high. The rotating sleeve 5042 and the rotating disk 805 have a matching shape, ensuring stable transmission of the rotary drive force and avoiding switching deviations caused by slippage.

A connecting assembly 804 is installed in the center of the interior of the mounting base 803. The connecting assembly 804 includes a rotating part 8041 rotatably connected to the mounting base 803, a threaded sleeve 8042, and an air guide hose 8043. The longitudinal section of the rotating part 8041 is designed in the shape of an "I" and a part with the shape of the insertion rod 1303 is opened at the center of the top of the rotating part 8041. The bottom of the rotating component 8041 is integrally connected to a threaded sleeve 8042, and one side of the threaded sleeve 8042 is connected to a vent hose 8043. The two exhaust ports of the three-way valve 601 are respectively connected to the two threaded sleeves 8042 through two vent hoses 8043. The rectangular plug 1303 of the power output assembly 13 is adapted to the slot 8044 on the top of the rotating component 8041 to ensure that the driving force of the rotary motor 1302 can be stably transmitted to the rotating component 8041, driving the soil extraction pipe 1005 / mineral extraction pipe 1106 to rotate downwards. Drilling prevents slippage; the small hydraulic telescopic rod 1301 can flexibly adjust the height of the rotary motor 1302 to achieve quick docking or separation of the insertion rod 1303 and the slot 8044; the servo motor 802 on the H-type mounting bracket 801 can adjust the angle of the mounting base 803 to ensure precise alignment of the soil sampling component 10 / mineral sampling component 11 with the power output component 13; the air guide hose 8043 of the connecting component 804 cooperates with the three-way valve 601 of the air pump 6 to achieve selective air supply from the air pump 6 to the soil sampling component 10 or the mineral sampling component 11, meeting the air pressure assistance requirements of different components.

[0028] Please see Figure 2The soil sampling assembly 10 includes a first threaded head 1001, a soil-breaking blade 1002, a first piston plate 1003, a first air hole 1004, and a soil sampling tube 1005. The top of the soil sampling tube 1005 is integrally provided with a first threaded head 1001 that is threadedly connected to a threaded sleeve 8042. A first air hole 1004 is opened at the center of the top of the soil sampling tube 1005. The first piston plate 1003 is disposed inside the soil sampling tube 1005, and a soil-breaking blade 1002 is integrally provided at the bottom of the soil sampling tube 1005. The first threaded head 1001 is integrally provided with a first piston plate 1003 inside the soil sampling tube 1005, and a soil-breaking blade 1002 is integrally provided at the bottom of the soil sampling assembly 10. A threaded head 1001 is threadedly connected to the threaded sleeve 8042 of the connecting component 804, which facilitates the disassembly and maintenance of the soil sampling tube 1005; the soil-breaking blade 1002 at the bottom of the soil sampling tube 1005 can quickly break through the soil layer, reduce the drilling resistance of the soil sampling tube 1005, and improve the soil sampling efficiency; the first piston plate 1003 inside the soil sampling tube 1005 cooperates with the first air hole 1004 at the top, and the first piston plate 1003 can be driven by air pressure to move, so as to realize the rapid extraction of soil samples and avoid the samples getting stuck in the soil sampling tube 1005 and being difficult to clean.

[0029] Please see Figure 2The ore extraction assembly 11 includes a second threaded head 1101, an alloy ring cutter 1102, a second piston plate 1103, a second vent 1104, an ore extraction pipe 1106, and a retaining structure 12. The top of the ore extraction pipe 1106 is integrally provided with a second threaded head 1101 that is threadedly connected to a threaded sleeve 8042. A second vent 1104 is provided at the center of the top of the ore extraction pipe 1106. The second piston plate 1103 is slidably disposed inside the ore extraction pipe 1106, and the outer diameter of the second piston plate 1103 matches the inner diameter of the ore extraction pipe 1106. The bottom of the ore extraction pipe 1106 is threadedly connected to an alloy ring cutter 1102. A retaining structure 12 is provided at the bottom end inside the ore extraction pipe 1106, and the retaining structure 12 includes… The structure includes a retaining plate 1201, a hinge seat 1202, and a return spring 1203. Six slots 1105 are equally spaced on the wall of the ore extraction pipe 1106 above the alloy ring cutter 1102. Each slot 1105 has a hinge seat 1202 at its bottom end, and a retaining plate 1201 is hinged to each hinge seat 1202. The retaining plate 1201 is a one-sixth fan-shaped design with a diameter matching the inner diameter of the ore extraction pipe 1106. A return spring 1203 connects the bottom end of each slot 1105 to the retaining plate 1201. Under normal conditions, the return spring 1203 is in a naturally extended state, which can keep the retaining plate 1201 horizontal. At this time, the six retaining plates 1201 are joined together to form a shape matching the inner diameter of the ore extraction pipe 1106. The circular baffle 1201 forms a horizontal barrier inside the ore extraction pipe 1106. When the ore extraction pipe 1106 is drilled down to collect ore samples: if it comes into contact with loose soil, the soil particles will be blocked by the horizontal baffle 1201 and will not be able to enter the ore extraction pipe 1106, and will be discharged from the slot 1105; if it comes into contact with hard ore, the squeezing force of the ore on the baffle 1201 is greater than the tension of the return spring 1203, which can push the baffle 1201 to rotate upward around the hinge seat 1202 to a vertical position. At this time, the outer wall of the baffle 1201 is flush with the outer wall of the ore extraction pipe 1106, and the inner wall does not protrude into the ore extraction pipe 1106, so it will not obstruct the entry of the ore sample and ensure that the ore can form a complete cylindrical core for ore extraction. During ore unloading, the air pump 6 inputs air pressure into the ore extraction pipe 1106 through the air guide hose 8043, pushing the second piston plate 1103 downward. When the second piston plate 1103 moves to the slot 1105 position, the air pressure will leak from the slot 1105, and the second piston plate 1103 will stop moving forward, which can prevent the ore core from being directly pushed out and broken. The staff can manually pull out the ore core sample to ensure the integrity of the sample. The alloy ring cutter 1102 of the ore extraction component 11 has high hardness and can accurately cut hard ore to ensure the integrity of the ore core sample. The soil retaining structure 12's soil retaining plate 1201 and the return spring 1203 cooperate to prevent soil from entering the ore extraction pipe 1106 and only allow ore to enter, ensuring the purity of the ore sample.The slot 1105 in the wall of the ore extraction pipe 1106 can both discharge soil and restrict the movement of the second piston plate 1103 during ore unloading by controlling air pressure leakage, thus preventing the ore core from being directly pushed out and broken. The second threaded head 1101 at the top of the ore extraction pipe 1106 facilitates the disassembly and assembly of the ore extraction pipe 1106, and the internal second piston plate 1103 can assist in the removal of the ore core, improving operational convenience.

[0030] Detailed Implementation: In use, when the power is turned on and soil needs to be extracted, the adjusting motor 5041 of the rotary drive assembly 504 drives the rotating disk 805 of the H-type mounting bracket 801 to rotate, rotating the soil extraction assembly 10 directly below the power output assembly 13; the servo motor 802 adjusts the angle of the mounting base 803 so that the slot 8044 of the rotating part 8041 is aligned with the insertion rod 1303, and the small hydraulic telescopic rod 1301 pushes the rotary motor 1302 to descend, and the insertion rod 1303 is inserted into the slot 8044, completing the power connection; when extracting ore, the above operation is repeated to switch to the ore extraction assembly 11; when extracting soil, the rotary motor 1302 drives the soil extraction pipe 1005 to rotate. Hydraulic cylinder 7 drives it to drill down along guide sleeve 3, soil-breaking blade 1002 cuts through the soil, and the soil enters soil sampling pipe 1005; during ore extraction, alloy ring cutter 1102 of ore sampling pipe 1106 cuts the ore, and retaining plate 1201 of retaining structure 12 prevents soil from being discharged from the opening 1105. The ore pushes retaining plate 1201 into the pipe. During soil unloading, air pump 6 supplies air to soil sampling pipe 1005 through air guide hose 8043. The air pressure pushes first piston plate 1003 through first air hole 1004 to push out soil sample; during ore unloading, air pressure pushes second piston plate 1103 until air pressure leaks at opening 1105, and workers manually pull out ore core to complete sampling.
