Description

Technical Field

[0001] This invention relates to the field of mineral layer physical property detection technology, specifically to multi-dimensional mineral layer physical property detection equipment. Background Technology

[0002] Ore layer physical property detection is a crucial step in mineral resource exploration and development. Its core involves collecting ore layer samples at target depths and analyzing their composition, structure, hardness, and other physicochemical properties to provide vital data support for mineral resource reserve assessment and mining plan development. As mineral exploration extends to deeper and more complex veins, higher demands are placed on the sampling accuracy, ease of operation, and adaptability of detection equipment. Highly efficient and reliable ore layer physical property detection equipment has become an industry necessity.

[0003] Existing mineral layer physical property detection equipment has several shortcomings in practical applications: some equipment lacks effective limiting and guiding structures, making it prone to deflection during drilling, resulting in deviations between the sampling depth and the target position, and the collected mineral samples failing to accurately reflect the physical properties of the corresponding mineral layer depth; simultaneously, the opening and closing control precision of the sampling mechanism is insufficient, easily leading to sample spillage or insufficient collection, affecting the accuracy of subsequent analysis data. Furthermore, the sample retrieval process after sampling with existing equipment is cumbersome, and the moving parts lack scientific speed control and protective design, resulting in severe wear after long-term use. This not only increases maintenance costs but also easily leads to detection interruptions due to component failure, reducing overall detection efficiency. To address these technical problems, this application proposes a multi-dimensional mineral layer physical property detection device. Summary of the Invention

A sliding rod is fixedly connected to the inner wall of the rotating frame. A lifting plate is sleeved on the outer wall of the sliding rod. An auger is rotatably connected to the middle end of the lifting plate. A sampling shell is fixedly connected to the bottom side of the auger. A drill bit is fixedly connected to the bottom end of the sampling shell. The outer wall of the lifting plate is connected to the side plate through a limiting component. A driving component is provided on the bottom side of the lifting plate.

[0007] A sampling support box is fixedly connected to the outer wall of the sampling shell. An upper cover plate is rotatably connected to the top of the sampling support box, and a lower cover plate is rotatably connected to the bottom of the sampling support box. A sampling plate is bolted to the bottom of the lower cover plate. A fixing block is fixedly connected to the inner wall of the sampling support box, and a guide rod is provided on the inner wall of the fixing block.

[0008] A hydraulic branch pipe is fixedly connected to the inner wall of the sampling shell. Piston rods are provided inside both ends of the hydraulic branch pipe, and a hydraulic component is provided at the middle end of the hydraulic branch pipe.

[0009] The detection component includes a property sensor, a data acquisition module, and a wireless transmission module installed on the inner wall of the sampling housing. The detection end of the property sensor penetrates through the side wall of the sampling housing and extends to the outside. The data acquisition module is electrically connected to the property sensor and the wireless transmission module, respectively. The wireless transmission module is signal-connected to an external terminal device.

[0010] Preferably, the limiting component includes a limiting rod fixedly connected to the outer wall of the lifting plate, the outer wall of the side plate has a vertical groove, the top of the vertical groove has an arc-shaped groove, and the limiting rod is disposed on the inner wall of the arc-shaped groove.

[0011] Preferably, the drive assembly includes a motor mounted on the top side of the lifting plate via a fixing frame, the drive end of the motor being fixedly connected to the top of the auger, and a hydraulic rod mounted on the top of the rotating frame, the drive end of the hydraulic rod being fixedly connected to the top side of the lifting plate.

[0012] Preferably, the linkage assembly includes two fixed sleeves fixedly connected to the outer wall of the guide rod. The outer wall of the upper fixed sleeve is rotatably connected to a first connecting rod, the bottom end of which is rotatably connected to the inner wall of the upper cover plate. The outer wall of the lower fixed sleeve is rotatably connected to a second connecting rod, the bottom end of which is rotatably connected to the inner wall of the lower cover plate.

[0013] Preferably, the hydraulic assembly includes an electric push rod installed on the inner wall of the sampling housing, a piston head fixedly connected to the drive end of the electric push rod, a hydraulic main pipe fixedly connected to the middle end of the hydraulic branch pipe, and the piston head disposed inside the hydraulic main pipe.

[0014] Preferably, the bottom end of the guide rod is slidably connected to the inner wall of the sampling support box, and the top end of the piston rod is fixedly connected to the bottom end of the guide rod.

[0015] Preferably, the physical property sensor includes a hardness sensor, a humidity sensor, and a composition detection sensor. The hardness sensor is used to detect the hardness of the ore layer rock in real time, the humidity sensor is used to detect the water content of the ore layer, and the composition detection sensor is used to preliminarily detect the main elemental composition of the ore layer. The data acquisition module has a built-in storage unit that can synchronously store sensor detection data and sampling depth information. The wireless transmission module supports either 5G or Wi-Fi transmission to realize real-time remote transmission of detection data.

[0016] A multi-dimensional method for detecting the physical properties of ore layers includes the following steps:

[0017] Step 1: Fix the base frame to the detection area, check the component connections, ensure that the limit rod is in the arc groove and the upper and lower cover plates are closed, and conduct a pre-run to verify the stability of each power component;

[0018] Step 2: Start the hydraulic rod to drive the lifting plate to move down, and the motor drives the auger, sampling housing and drill bit to rotate; the limit rod moves along the vertical groove to prevent deflection and ensure vertical drilling;

[0019] Step 3: After drilling to the target depth, keep the sampling shell rotating at a low speed, start the electric push rod to drive the guide rod down through hydraulic transmission, and link the first and second connecting rods to open the upper and lower cover plates, scrape the sample and let it fall into the sampling support box.

[0020] Step 4: After sampling is completed, reverse the electric push rod to close the cover plate; the hydraulic rod drives the lifting plate to move up, the limit rod falls into the arc groove, and drives the rotating frame and the sampling shell to deflect.

[0021] Step 5: Remove the sampling plate bolts, open the sampling plate and take out the sample from the sampling support box to complete one detection.

[0022] Preferably, during the pre-run of step one, it is necessary to check whether the extension and retraction stroke of the hydraulic rod and the electric push rod meet the standard to ensure that the upper and lower covers of the sampling support box open and close flexibly without jamming.

[0023] Preferably, in step two, the downward movement speed of the hydraulic rod and the rotation speed of the motor need to be matched to ensure that the drill bit cuts smoothly. In step four, the upward movement speed of the lifting plate is lower than the downward movement speed to ensure that the limit rod falls smoothly into the arc groove and reduce component wear.

[0024] Working Principle: First, after the equipment is positioned using the base frame, the hydraulic rod and motor start synchronously. The hydraulic rod drives the lifting plate to move vertically downwards along the slide bar, while the motor drives the auger, sampling housing, and drill bit to rotate. Simultaneously, the limit rod moves along the vertical groove of the side plate, limiting the deflection of the rotating frame and ensuring the drill bit drills vertically into the ore layer. When the borehole reaches the target depth, the electric push rod starts, pushing the piston head to move within the hydraulic main pipe. This, in turn, drives the piston rod to retract via the hydraulic branch pipe, causing the guide rod to move downwards. The guide rod, through the fixed sleeve, links connecting rod one and rod two, causing the upper and lower covers of the sampling box to open. The rotating sampling housing scrapes the ore sample through the upper cover plate, and the sample slides down the cover plate into the sampling box to complete the sampling. After sampling, the electric push rod reverses its movement to close the cover plate, and the hydraulic rod drives the lifting plate to move upwards. When the limit rod disengages from the vertical groove and falls into the arc-shaped groove, the arc-shaped groove guides the rotating frame and sampling housing to deflect, facilitating subsequent disassembly of the sampling plate and sample removal.

[0025] This invention provides a multi-dimensional mineral layer physical property detection device. It has the following beneficial effects:

[0026] 1. This invention ensures vertical drilling through the combination of a limiting rod and a vertical groove. The hydraulic rod and motor work together to adjust speed to adapt to different mineral layer hardnesses, achieving smooth cutting. An electric push rod and hydraulic transmission structure drive the guide rod downwards, linking connecting rod one and connecting rod two to precisely open and close the upper and lower cover plates. The sampling shell rotates at low speed to scrape the sample, and the cover plates close to prevent spillage, ensuring the mineral sample is intact and accurately reflects the mineral layer properties, thus improving the accuracy of the detection data.

[0027] 2. After sampling is completed, the limiting rod falls into the arc-shaped groove, causing the rotating frame and sampling shell to deflect. Combined with the bolted connection design of the sampling plate, this facilitates quick disassembly and sampling. Pre-operation testing can identify faults in components such as hydraulic rods and electric push rods in advance. The upward speed of the lifting plate is lower than its downward speed, reducing wear on the limiting rod and the arc-shaped groove, extending the equipment's service life. The modular structure also facilitates component maintenance and replacement. Attached Figure Description

[0036] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a multi-dimensional mineral layer physical property detection device, including:

[0037] A side plate 2 is fixedly connected to the middle of the base frame 1. A rotating frame 5 is rotatably connected to the inner wall of the side plate 2.

A drill bit 10 is fixedly connected to the bottom end of the sampling shell 9. A limiting rod 13 is fixedly connected to the outer wall of the lifting plate 7. A vertical groove 3 is opened on the outer wall of the side plate 2. An arc groove 4 is opened at the top of the vertical groove 3. The limiting rod 13 is set on the inner wall of the arc groove 4. A motor 12 is installed on the top side of the lifting plate 7 through a fixed frame. The driving end of the motor 12 is fixedly connected to the top of the auger 8. A hydraulic rod 6 is installed on the top of the rotating frame 5. The driving end of the hydraulic rod 6 is fixedly connected to the top side of the lifting plate 7.

[0038] Specifically, the base frame 1 is made of high-strength alloy material to ensure the overall stability of the equipment. Its bottom can be fixed to the ground of the detection area by expansion bolts to prevent the equipment from shaking during drilling. The side plate 2 is welded to the base frame 1. The rotating frame 5 rotates with the inner wall of the side plate 2 through bearings to reduce rotational friction. Two slide rods 11 are set and symmetrically distributed on both sides of the inner wall of the rotating frame 5 to ensure that the lifting plate 7 is subjected to balanced force during the downward movement and to avoid tilting. The motor 12 is a servo motor 12, which can precisely adjust the rotation speed. The hydraulic rod 6 is a double-acting hydraulic rod 6 to ensure that the lifting plate 7 moves smoothly and has sufficient downward pressure to meet the drilling needs of mineral layers with different hardness.

[0039] Please see the appendix Figure 3 -Appendix Figure 5 The sampling support box 14 is fixedly connected to the outer wall of the sampling housing 9. An upper cover plate 15 is rotatably connected to the top of the sampling support box 14, and a lower cover plate 16 is rotatably connected to the bottom of the sampling support box 14. A sampling plate 17 is bolted to the bottom of the lower cover plate 16. A fixing block 27 is fixedly connected to the inner wall of the sampling support box 14. A guide rod 23 is provided on the inner wall of the fixing block 27. Two fixing sleeves 24 are fixedly connected to the outer wall of the guide rod 23. A connecting rod 1 21 is rotatably connected to the outer wall of the upper fixing sleeve 24, and the bottom of the connecting rod 1 21 is rotatably connected to the inner wall of the upper cover plate 15. A connecting rod 22 is rotatably connected to the outer wall of the lower fixing sleeve 24, and the bottom of the connecting rod 22 is rotatably connected to the inner wall of the lower cover plate 16. The bottom of the guide rod 23 is slidably connected to the inner wall of the sampling support box 14. The top end of the stopper rod 25 is fixedly connected to the bottom end of the guide rod 23. The detection component and the physical property sensors include a hardness sensor, a humidity sensor, and a composition detection sensor. The hardness sensor is used to detect the hardness of the ore layer rock in real time, the humidity sensor is used to detect the water content of the ore layer, and the composition detection sensor is used to preliminarily detect the main elemental composition of the ore layer. The data acquisition module has a built-in storage unit that can synchronously store sensor detection data and sampling depth information. The wireless transmission module supports either 5G or Wi-Fi transmission to realize real-time remote transmission of detection data. The detection end of the physical property sensor penetrates through the side wall of the sampling shell 9 and extends to the outside. The data acquisition module is electrically connected to the physical property sensor and the wireless transmission module respectively. The wireless transmission module is signal connected to the external terminal device.

[0040] Specifically, the sampling box 14 is made of wear-resistant stainless steel, and its inner wall is polished smooth to avoid sample residue. The upper cover plate 15 and the lower cover plate 16 are rotatably connected to the sampling box 14 by hinges, and the hinges are coated with lubricant to ensure flexible opening and closing. The length of the second connecting rod 22 is 2-3cm longer than that of the first connecting rod 21, ensuring that the opening angle of the lower cover plate 16 is greater than that of the upper cover plate 15, forming a funnel-shaped guide structure to facilitate sample sliding. The fixing sleeve 24 and the guide rod 23 are fixed by an interference fit. The first connecting rod 21 and the second connecting rod 22 are respectively connected to the fixing sleeve 24, the upper cover plate 15 and the lower cover plate 16 by pins. Plate 16 is rotatably connected, with anti-slip washers at the pin to prevent loosening during operation. The hardness sensor in the physical property sensor provides feedback on hardness values ​​based on the contact pressure between the probe end and the ore layer rock, with a detection range of 1-10 (Shore hardness) and an accuracy of ±0.2. The humidity sensor detects the moisture content of the ore layer through changes in capacitance at the probe end, with a detection range of 0-30% and an accuracy of ±0.5%. The composition detection sensor uses X-ray fluorescence detection to preliminarily detect the relative content of 10 common ore layer elements, including Si, Fe, Cu, and Al, with a detection error not exceeding 5%. The data acquisition module collects sensor data every 0.5 seconds and binds it with the depth data fed back by the displacement sensor of hydraulic rod 6 (newly added, installed on the hydraulic rod cylinder) to form a "depth-physical property" correlated dataset. This dataset is transmitted in real-time to an external terminal (such as a laptop or tablet) via a wireless transmission module. The terminal device can generate real-time data curves, allowing operators to intuitively observe the changes in ore layer properties with depth.

[0041] Please see the appendix Figure 2 -Appendix Figure 4 The hydraulic branch pipe 20 is fixedly connected to the inner wall of the sampling housing 9. Both ends of the hydraulic branch pipe 20 are equipped with piston rods 25. An electric push rod 19 is installed on the inner wall of the sampling housing 9. The drive end of the electric push rod 19 is fixedly connected to a piston head 26. The middle end of the hydraulic branch pipe 20 is fixedly connected to a hydraulic main pipe 18. The piston head 26 is located inside the hydraulic main pipe 18.

[0042] Specifically, the hydraulic main pipe 18 and hydraulic branch pipe 20 adopt an integral molding structure, filled with anti-wear hydraulic oil, and a sealing gasket is set at the connection to prevent hydraulic oil leakage; the outer wall of the piston head 26 is fitted with a rubber sealing ring to enhance the sealing performance; the electric push rod 19 is an electric hydraulic push rod, which can precisely control the movement stroke of the piston head 26, thereby controlling the extension and retraction of the piston rod 25, and realizing the precise adjustment of the opening angle of the upper cover plate 15 and the lower cover plate 16; the top end of the piston rod 25 is threaded to the bottom end of the guide rod 23 for easy disassembly and maintenance; the detection end of the physical property sensor is encapsulated with wear-resistant ceramic material to avoid wear by mineral particles during drilling; its installation position is located in the middle of the side wall of the sampling shell 9, with a distance of 15-20cm from the drill bit 10. The system ensures that the probe can reach the target depth of the mineral layer without affecting drill bit cutting. The data acquisition module uses a low-power microcontroller with a built-in AD conversion module, which can convert the analog signals collected by the sensor into digital signals. The storage unit has a capacity of no less than 16GB and supports cyclic storage. It also records the timestamp and sampling depth data for each detection, with the depth data calculated by the extension and retraction stroke of the hydraulic rod 6. The wireless transmission module integrates a signal enhancement antenna, which is installed in a groove at the top of the sampling housing 9. A waterproof and dustproof cover is installed on the outside of the groove to ensure the stability of signal transmission and prevent damage to components. The power supply terminal of the detection component is electrically connected to the built-in lithium battery of the device. The lithium battery has a capacity of no less than 10000mAh and supports 8-12 hours of continuous operation.

[0043] A multi-dimensional method for detecting the physical properties of ore layers includes the following steps:

[0044] Step 1: Fix the base frame 1 to the detection area, check the component connections, and ensure that the limit rod 13 is in the arc groove 4, the upper cover plate 15 and the lower cover plate 16 are closed. Perform a pre-run to verify the stability of each power component. During the pre-run, it is necessary to check whether the extension and retraction stroke of the hydraulic rod 6 and the electric push rod 19 meet the standards, and ensure that the upper and lower cover plates 16 of the sampling support box 14 open and close flexibly without jamming.

[0045] Specifically, during positioning, first calibrate the level of the base frame 1 using a level, controlling the horizontal deviation within 0.5°; during inspection, focus on checking whether the bolt connections, hydraulic pipeline interfaces, and motor 12 wiring connections are secure; during pre-run, control the hydraulic rod 6 to rise and fall twice in its full stroke, and the electric push rod 19 to drive the piston head 26 to move back and forth three times, observing whether the upper cover plate 15 and lower cover plate 16 open and close smoothly without any jamming, abnormal noise, or other abnormalities. If jamming occurs, promptly check the connecting rod connection or add lubricating oil.

[0046] Step 2: Start the hydraulic rod 6 to drive the lifting plate 7 to move down, and the motor 12 drives the auger 8, sampling shell 9 and drill bit 10 to rotate; the limit rod 13 moves along the vertical groove 3 to prevent deflection and ensure vertical drilling. The downward speed of the hydraulic rod 6 and the rotation speed of the motor 12 must be matched to ensure that the drill bit cuts smoothly.

[0047] Specifically, based on the ore layer hardness adjustment parameters, for coal seams with lower hardness, the downward movement speed of hydraulic rod 6 is set to 1.5-2 cm / s, and the rotation speed of motor 12 is set to 25-30 r / min; for rock seams with higher hardness, the downward movement speed is set to 0.5-1 cm / s, and the rotation speed is set to 10-15 r / min. During the downward movement, the drilling direction of drill bit 10 is monitored by visual observation or infrared positioning to ensure that the vertical deviation does not exceed 1°. If a deviation occurs, the machine is stopped in time to check the fit between limit rod 13 and vertical groove 3. During the drilling process, physical property sensors detect the ore layer hardness, moisture content, and main elemental composition in real time. The data acquisition module synchronously collects sensor data and real-time depth data converted from the extension stroke of hydraulic rod 6, and sends it to external terminal equipment through wireless transmission module. Operators can monitor the changes in ore layer physical properties in real time.

[0048] Step 3: After drilling to the target depth, keep the sampling shell 9 rotating at a low speed, start the electric push rod 19 to drive the guide rod 23 to move down through hydraulic transmission, and link the first connecting rod 21 and the second connecting rod 22 to open the upper cover plate 15 and the lower cover plate 16, scrape the sample and let it fall into the sampling support box 14. During this process, the physical property sensor continuously detects the physical property data of the mineral layer at the target depth, collects 3-5 sets of data and takes the average value as the core detection result of the physical property of the mineral layer at that depth, and stores and transmits it.

[0049] Specifically, the target depth is calculated by the downward stroke of the lifting plate 7, and a scale is set on the slide bar 11 to accurately read the downward distance; during sampling, the speed of the motor 12 is reduced to 5-8 r / min to avoid sample splashing caused by high-speed rotation; the electric push rod 19 drives the piston head 26 to move at a speed controlled at 0.2-0.3 cm / s, slowly opening the upper cover plate 15 and the lower cover plate 16, and holding it open for 5-10 seconds to ensure that a sufficient amount of sample is scraped and slides into the sampling box 14.

[0050] Step 4: After sampling is completed, the electric push rod 19 is started in reverse to close the cover plate; the hydraulic rod 6 drives the lifting plate 7 to move upward, and the limit rod 13 falls into the arc groove 4, which drives the rotating frame 5 and the sampling shell 9 to deflect. The upward speed of the lifting plate 7 is lower than the downward speed to ensure that the limit rod 13 falls smoothly into the arc groove 4 and reduce component wear.

[0051] Specifically, after the cover is closed, it can be visually confirmed that the closure is in place to prevent the sample from falling during the upward movement; the upward movement speed of the lifting plate 7 is set to 0.3-1.5 cm / s, which is 0.2-0.5 cm / s lower than the downward movement speed; after the limiting rod 13 falls into the arc groove 4, the rotating frame 5 deflects at an angle of 15-30°. The deflection angle can be controlled by the arc design of the arc groove 4 to ensure that the sampling support box 14 is in an easy-to-operate position after deflection, avoiding interference with other components. During the upward movement, the physical property sensor can detect the physical property data of different depths of the ore layer again and compare it with the detection results during the downward movement to form a multi-dimensional data reference.

[0052] Step 5: Remove the bolts of sampling plate 17, open sampling plate 17 and take out the sample from sampling support box 14 to complete one detection.

[0053] Specifically, when disassembling bolts, use a matching wrench to avoid damaging the threads by using excessive force; when taking out samples, use a special sampling spoon to take the samples out into the sample bag, mark them, and record information such as sampling depth and location; after sampling, clean the inner wall of the sampling support box 14, close the sampling plate 17 and tighten the bolts to prepare for the next detection.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

8. A multi-dimensional mineral layer physical property detection method, using the multi-dimensional mineral layer physical property detection equipment as described in claims 1-7, characterized in that, Includes the following steps: Step 1: Fix the base frame (1) to the detection area, check the component connections, ensure that the limit rod (13) is located in the arc groove (4), and the upper and lower cover plates are closed. Perform a pre-run to verify the stability of each power component. Step 2: Start the hydraulic rod (6) to drive the lifting plate (7) to move down, and the motor (12) drives the auger (8), sampling shell (9) and drill bit (10) to rotate; the limit rod (13) moves along the vertical groove (3) to prevent deflection and ensure vertical drilling; Step 3: After drilling to the target depth, keep the sampling shell (9) rotating at a low speed, start the electric push rod (19) to drive the guide rod (23) down through hydraulic transmission, and link the first link (21) and the second link (22) to open the upper cover plate (15) and the lower cover plate (16), scrape the sample and let it fall into the sampling support box (14). Step 4: After sampling is completed, the electric push rod (19) is activated in reverse to close the cover plate; the hydraulic rod (6) drives the lifting plate (7) to move upward, and the limiting rod (13) falls into the arc groove (4), causing the rotating frame (5) and the sampling shell (9) to deflect; Step 5: Remove the bolts of the sampling plate (17), open the sampling plate and take out the sample from the sampling support box (14) to complete one detection.

9. The multi-dimensional mineral layer physical property detection method according to claim 8, characterized in that, In step one, during the pre-run, it is necessary to check whether the extension and retraction strokes of the hydraulic rod (6) and the electric push rod (19) meet the standards, and ensure that the upper and lower covers of the sampling support box (14) open and close flexibly without jamming.

10. The multi-dimensional mineral layer physical property detection method according to claim 8, characterized in that, In step two, the downward movement speed of the hydraulic rod (6) and the rotation speed of the motor (12) need to be matched to ensure that the drill bit cuts smoothly. In step four, the upward movement speed of the lifting plate (7) is lower than the downward movement speed to ensure that the limit rod (13) falls smoothly into the arc groove (4) and reduce component wear.
