Description

Technical Field

[0001] The invention relates to the technical field of exploration and sampling, in particular to a mineral resource exploration and sampling device. Background Art

[0002] The task of mineral exploration is to discover and identify industrial mineral deposits. To this end, geological mapping, geophysical prospecting, geochemical prospecting, drilling and pit prospecting and other prospecting methods should be used. Sampling and analysis should be carried out, ore quality should be studied, ore bodies should be delineated using industrial indicators and reserves should be calculated, ore selection and metallurgical technical properties and hydrological and engineering geological conditions for mining of mineral deposits should be studied, technical and economic evaluation of mineral deposits should be made, and geological exploration reports should be compiled.

[0003] According to a Chinese invention patent with the announcement number CN114608868B, a portable sampling device for mineral exploration is disclosed. By installing a top plate, a fixed plug rod, a sampling rod, a sampling barrel, a servo motor, a drive shaft, a transmission assembly, a first gear and a fixed rack, the servo motor drives the drive shaft to rotate, and the drive shaft drives each sampling rod to rotate through the transmission assembly. At the same time, the moving plate can move up and down as a whole under the action of the first gear and the fixed rack, that is, the sampling barrel can also move up and down while rotating, so that multi-point synchronous sampling can be completed at one time. The operation is simple and convenient, and the sampling efficiency is effectively improved. After using the device, it was found that the above device can quickly push out the sample in the sampling tube when the push plate moves downward during sampling. However, due to the direct contact between the rock core and the inner wall of the sampling tube and the hard texture of the rock core, the friction between the rock core and the inner wall of the sampling tube is directly pushed, which can easily cause scratches on the inner wall of the sampling tube, resulting in abnormal wear of the inner wall of the sampling tube. After the rock core of the above device is pushed out from the inside of the sampling tube, it is easy to fall directly due to gravity, increasing the risk of the rock core being broken, which is not conducive to the exploration of various texture distributions in the rock core. For this reason, we propose a mineral resource exploration sampling device to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 13 The technical solution provided by the present invention specifically includes the following embodiments:

[0035] Embodiment 1: A mineral resource exploration sampling device, comprising a frame 100, wherein a sampling component 200 is rotatably arranged inside the frame 100, wherein the sampling component 200 comprises two arc-shaped sampling tubes 201, wherein the two arc-shaped sampling tubes 201 are both arranged in a semi-cylindrical shape, and the two arc-shaped sampling tubes 201 are symmetrically distributed, wherein the lower parts of the inner walls of the two arc-shaped sampling tubes 201 are provided with arc receiving grooves 202, wherein the two arc receiving grooves 202 are connected to each other, and the top and bottom walls of the two arc receiving grooves 202 are provided with spring placement grooves 203, wherein the upper and lower springs are arranged on the upper and lower walls of the two arc receiving grooves 203. A torsion bar 204 is rotatably mounted between the spring placement grooves 203, and an elastic bandage 205 is fixedly mounted on the outer walls of the two torsion bars 204. The elastic bandage 205 is located inside the two arc receiving grooves 202, and a friction strip 206 is fixedly mounted on the inner wall of the elastic bandage 205. The two arc receiving grooves 202 are symmetrically distributed about the central axis of the arc-shaped sampling tube 201. The number of the elastic bandage 205 and the friction strip 206 is two, and the two elastic bandages 205 and the two friction strips 206 are symmetrically distributed about the center of the arc-shaped sampling tube 201.

[0036] The tops of the two arc-shaped sampling tubes 201 are fixedly installed with connecting top blocks 208, and the tops of the two connecting top blocks 208 are respectively fixedly installed with a first connecting seat 209 and a second connecting seat 2023. Two assembly holes 2010 are penetrated and provided on one side of the first connecting seat 209 close to the second connecting seat 2023, and the assembly holes 2010 are symmetrically distributed about the central axis of the first connecting seat 209. Two guide holes 2024 are penetrated and provided on one side of the second connecting seat 2023 close to the first connecting seat 209. The positions of the guide holes 2024 correspond to the positions of the assembly holes 2010 one by one. Guide rods 2011 are fixedly installed inside the two assembly holes 2010, and the outer wall of the guide rod 2011 is slidably connected to the inner wall of the guide hole 2024. A cover tile seat 2012 is fixedly installed on the periphery of the two guide rods 2011. A hydraulic motor 2013 is provided on the top of the cover tile seat 2012, and the bottom of the output shaft of the hydraulic motor 2013 is fixedly connected to the top of the cover tile seat 2012.

[0037] A servo motor 2017 is fixedly installed on the side of the first connecting seat 209 away from the second connecting seat 2023, and a screw 2018 is fixedly installed on the end of the output shaft of the servo motor 2017. The screw 2018 movably passes through the first connecting seat 209 and the second connecting seat 2023, and the outer periphery of the screw 2018 is threadedly connected with a guide block 2019. The guide block 2019 is located on the side of the second connecting seat 2023 away from the first connecting seat 209, and sliding holes 2020 are provided at both ends of a side surface of the guide block 2019 close to the second connecting seat 2023. The inner wall of the sliding hole 2020 is slidably connected to the outer wall of the guide rod 2011, and the outer periphery of the guide rod 2011 is sleeved with a tensioning spring 2022, and the tensioning spring 2022 is fixedly installed between the guide block 2019 and the second connecting seat 2023.

[0038] Specifically, the servo motor 2017 is started to drive the screw rod 2018 to rotate through its output shaft, and the guide block 2019 is driven to slide in a direction away from the second connection seat 2023 under the action of the threaded thrust of the screw rod 2018 and the guide block 2019. The two tensioning springs 2022 in a compressed state gradually rebound. As the output shaft of the servo motor 2017 continues to drive the screw rod 2018 to rotate, the guide block 2019 continues to move in a direction away from the second connection seat 2023 until the elastic force stored in the two tensioning springs 2022 is completely released. The guide block 2019 drives the second connection seat 2023 to move along the two guide rods 2011 in a direction away from the first connection seat 209 through the connection of the two tensioning springs 2022. The first connection seat 209 moves and drives an arc-shaped sampling tube 201 associated with it to move together through the connecting top block 208. The two arc-shaped sampling tubes 201 are separated, and the separation of the two arc-shaped sampling tubes 201 causes their inner walls to separate from the outer wall of the sampled core. The core automatically falls off from the bottom of the two arc-shaped sampling tubes 201 under the action of gravity, thereby facilitating the detection personnel to sample the core and improving the convenience of use. It should be noted that during the separation of the two arc-shaped sampling tubes 201, the two elastic bandages 205 and the friction strip 206 are stretched by the connecting action of the torsion bar 204, and the arc of the two elastic bandages 205 is gradually reduced, and the two friction strips 206 are contracted toward the middle, thereby abutting against the outer wall of the core. Due to the contact friction between the two friction strips 206 and the outer wall of the core, the speed of the core falling is slowed down, ensuring that the core will not hit the ground quickly after falling off from the bottom of the two arc-shaped sampling tubes 201, and the sampled core will not be broken due to the impact, thereby better surveying the distribution of mineral texture.

[0039] Furthermore, a torsion spring 207 is provided inside the spring placement groove 203, and the torsion spring 207 is located on the periphery of the torsion bar 204, and the torsion spring 207 is fixedly installed between the spring placement groove 203 and the opposite surface of the elastic bandage 205. When the two elastic bandages 205 are stretched, the elastic bandage 205 drives the two torsion bars 204 connected thereto to rotate, causing the torsion spring 207 on the periphery of the torsion bar 204 to be elastically twisted. Therefore, after the core sampling is completed, the output shaft of the servo motor 2017 drives the screw 2018 to rotate in the opposite direction, so that the derivation block 2019 Move toward the direction of the second connecting seat 2023, the deduction block 2019 moves and drives the second connecting seat 2023 to move through the two tensioning springs 2022, and the second connecting seat 2023 moves and drives an arc-shaped sampling tube 201 associated with it to move together through the connecting top block 208, so that the two arc-shaped sampling tubes 201 are closed, and the torsion bar 204 can be driven to rotate by the rebound force of the torsion spring 207, and the elastic bandage 205 and the friction strip 206 are arched into the interior of the receiving arc groove 202, and stored in the interior of the receiving arc groove 202, and will not interfere with subsequent sampling.

[0040] Embodiment 2: A coupling component 300 is provided inside the sampling component 200, and the coupling component 300 includes two split grooves 301 provided on the side of the arc-shaped sampling tube 201, wherein a movable bolt 302 is slidably installed inside the two split grooves 301 of one arc-shaped sampling tube 201, and a wedge surface 303 is provided on the top of the movable bolt 302, and a plurality of bolt buckles 304 distributed up and down are fixedly installed on the side of the movable bolt 302 away from the split groove 301, and a plurality of bolt posts 306 distributed up and down are fixedly installed inside the two split grooves 301 of the other arc-shaped sampling tube 201, and the positions of the bolt buckles 304 correspond to the positions of the bolt posts 306, and a reset spring 305 is fixedly installed between the bottom of the movable bolt 302 and the bottom wall of the split groove 301;

[0041] Two right-angle rods 307 are fixedly installed on one side of the deduction block 2019 close to the second connecting seat 2023. The right-angle rods 307 are movable through the interior of the second connecting seat 2023 and extend between the second connecting seat 2023 and the first connecting seat 209. A deduction frame 308 is fixedly installed at the bottom of the two right-angle rods 307. Both ends of the bottom of the deduction frame 308 are fixedly installed with protrusions 309. The position of the protrusion 309 corresponds to the top position of the movable bolt bar 302, and the bottom of the protrusion 309 is flush with the top of the arc-shaped sampling tube 201.

[0042] Specifically, in this embodiment, when sampling, the servo motor 2017 is started to make its output shaft drive the screw 2018 to rotate, and further under the thread thrust of the screw 2018 and the guide block 2019, the guide block 2019 is driven to slide in the direction away from the second connecting seat 2023, and the two tensioning springs 2022 in the compressed state gradually rebound. At the same time, the two right-angle rods 307 move together with the guide block 2019, and drive the two protrusions 309 to move away from the top of the two movable bolt bars 302 through the guide frame 308. The top of the two movable bolt bars 302 loses the downward pressure of the protrusions 309. Therefore, the two return springs 305 in the compressed state are rebounded, pushing the two movable bolt bars 302 together with the multiple bolt buckles 304 to move upward along the split grooves 301, so that the bolt buckles 304 and the bolt column 306 are released, and the two arc-shaped sampling tubes 201 are decoupled. In order to separate the two arc-shaped sampling tubes 201, after the core sampling is completed, the output shaft of the servo motor 2017 drives the screw 2018 to rotate in the opposite direction, so that the deduction block 2019 moves in the direction of the second connecting seat 2023, driving the two right-angle rods 307 to move. The movement of the right-angle rod 307 drives the two protrusions 309 to move through the deduction frame 308. During the movement of the two protrusions 309, they respectively generate downward wedge forces with the two wedge surfaces 303, thereby pushing the two movable bolt bars 302 downward, and the two return springs 305 are compressed and stored. The downward movement of the two movable bolt bars 302 further drives the multiple bolt buckles 304 to move downward, so that the multiple bolt buckles 304 are again buckled on the periphery of the multiple bolt columns 306, coupling the two arc-shaped sampling tubes 201, making the two arc-shaped sampling tubes 201 not easy to open, so as to improve the stability of the two arc-shaped sampling tubes 201 during sampling.

[0043] Embodiment three: A rodless cylinder 401 is slidably installed on the periphery of the two light columns 400, a sedimentation platform 2016 is fixedly installed between the two rodless cylinders 401, the top of the sedimentation platform 2016 is fixedly connected to the bottom of the hydraulic motor 2013, a two-stroke hydraulic pump 2014 is fixedly installed on the top of the frame 100, a circulating oil pipe 2015 is fixedly installed between the output end of the two-stroke hydraulic pump 2014 and the input end of the hydraulic motor 2013, and a drill bit 2025 is fixedly installed on the bottom of the arc-shaped sampling tube 201 by bolts.

[0044] Specifically, the hydraulic oil is pumped by a two-stroke hydraulic pump 2014, and the hydraulic oil is transported to the inside of the hydraulic motor 2013 through the circulating oil pipe 2015, so that the output shaft of the hydraulic motor 2013 drives the cover tile seat 2012 together with the guide rod 2011, the first connecting seat 209, the second connecting seat 2023, the two connecting top blocks 208 and the two arc-shaped sampling tubes 201 to rotate. The rotation of the two arc-shaped sampling tubes 201 drives the two drill bits 2025 to rotate. During this period, the two rodless cylinders 401 move downward along the two light columns 400 and are lowered by the sedimentation. The connection of platform 2016 drives the hydraulic motor 2013 to move downward, causing the two arc-shaped sampling barrels 201 to move downward during the rotation and drill into the formation for mining sampling. After the sampling is completed, the two-stroke hydraulic pump 2014 stops running, causing the output shaft of the hydraulic motor 2013 to stop rotating, that is, the two arc-shaped sampling barrels 201 stop rotating, and then the two rodless cylinders 401 are started to move upward along the two light columns 400, and the two arc-shaped sampling barrels 201 are pulled upward from the formation, and the core is taken out together during the upward pulling of the two arc-shaped sampling barrels 201.

[0045] In the present scheme, a mineral resource exploration sampling device is used to pump hydraulic oil through a two-stroke hydraulic pump 2014 when working, and the hydraulic oil is transported to the inside of a hydraulic motor 2013 through a circulating oil pipe 2015, so that the output shaft of the hydraulic motor 2013 drives the cover tile seat 2012 together with the guide rod 2011, the first connecting seat 209, the second connecting seat 2023, the two connecting top blocks 208 and the two arc-shaped sampling tubes 201 to rotate. The rotation of the two arc-shaped sampling tubes 201 drives the two drill bits 2025 to rotate together, and during this period, the two rodless cylinders 401 move downward along the two light columns 400. The hydraulic motor 2013 is driven to move downward through the connection of the settling table 2016, so that the two arc-shaped sampling barrels 201 move downward during the rotation and drill into the stratum for mining exploration sampling. After the sampling is completed, the two-stroke hydraulic pump 2014 stops running, causing the output shaft of the hydraulic motor 2013 to stop rotating, that is, the two arc-shaped sampling barrels 201 stop rotating, and then the two rodless cylinders 401 are started to move upward along the two light columns 400, and the two arc-shaped sampling barrels 201 are pulled upward from the stratum, and the cores are taken out together during the upward pulling of the two arc-shaped sampling barrels 201;

[0046] When sampling, the servo motor 2017 is started to make its output shaft drive the screw 2018 to rotate, and further under the thread thrust of the screw 2018 and the guide block 2019, the guide block 2019 is driven to slide in the direction away from the second connecting seat 2023, and the two tension springs 2022 in the compressed state gradually rebound. At the same time, the two right-angle rods 307 move together with the guide block 2019, and drive the two protrusions 309 to move away from the tops of the two movable bolt bars 302 through the guide frame 308, and the tops of the two movable bolt bars 302 lose the downward pressure of the protrusions 309. Therefore, the two return springs 305 in the compressed state are rebounded, pushing the two movable bolt bars 302 together with the multiple bolt buckles 304 to move upward along the split grooves 301, so that the bolt buckles 304 are released from the bolt column 306, so as to separate the two arc-shaped sampling tubes 201. As the output shaft of the servo motor 2017 continues to drive the screw rod 2018 to rotate, the derivation block 2019 continues to move away from the second connecting seat 2023 until the elastic force stored in the two tensioning springs 2022 is completely released, and the derivation block 2019 is released by the two tensioning springs 2022. The connecting effect drives the second connecting seat 2023 to move along the two guide rods 2011 in the direction away from the first connecting seat 209. The movement of the first connecting seat 209 drives an arc-shaped sampling tube 201 associated with it to move together through the connecting top block 208, resulting in the separation of the two arc-shaped sampling tubes 201. The separation of the two arc-shaped sampling tubes 201 causes the inner walls thereof to separate from the outer walls of the sampled rock cores. The rock cores automatically fall off from the bottoms of the two arc-shaped sampling tubes 201 under the action of gravity, thereby facilitating the detection personnel to sample the rock cores and improving the convenience of use. It should be noted that the two arc-shaped sampling tubes 201 are During the separation of the arc-shaped sampling tube 201, the two elastic bandages 205 and the friction strips 206 are stretched by the connecting action of the torsion bar 204, and the arc of the two elastic bandages 205 is gradually reduced, so that the two friction strips 206 are contracted toward the middle, thereby abutting against the outer wall of the core. Due to the contact friction between the two friction strips 206 and the outer wall of the core, the falling speed of the core is slowed down, ensuring that the core will not hit the ground quickly after falling off from the bottom of the two arc-shaped sampling tubes 201, and the sampled core will not be broken due to the impact, so as to better survey the distribution of mineral texture;

[0047] While the two elastic bandages 205 are being stretched, the elastic bandages 205 drive the two torsion bars 204 connected thereto to rotate, causing the torsion springs 207 on the periphery of the torsion bars 204 to be elastically twisted. Therefore, after the core sampling is completed, the output shaft of the servo motor 2017 drives the screw 2018 to rotate in the opposite direction, causing the derivation block 2019 to move in the direction of the second connecting seat 2023. The movement of the derivation block 2019 drives the second connecting seat 2023 to move through the two tensioning springs 2022. The movement of the second connecting seat 2023 drives an arc-shaped sampling tube 201 associated therewith to move together through the connecting top block 208, so that the two arc-shaped sampling tubes 201 are closed, and the torsion bar 204 can be driven to rotate by the rebound force of the torsion spring 207, so that the elastic bandage 205 and the friction strip 206 are arched and sent to the inside of the receiving arc groove 202, and stored in the inside of the receiving arc groove 202, without interfering with subsequent sampling. As the output shaft of the servo motor 2017 continues to drive the screw rod 2018 to reverse, the guide block 2019 continues to move in the direction of the second connecting seat 2023, further compressing the two tensioning springs 2022, and the guide block 2019 continues to move to drive the two right-angle rods 307 to move, and the right-angle rod 307 moves through the guide frame 308 to drive the two protrusions 309 to move. During the movement of the two protrusions 309, they respectively generate downward wedge forces with the two wedge surfaces 303, thereby pushing the two movable bolt bars 302 downward, the two reset springs 305 are compressed and stored, and the downward movement of the two movable bolt bars 302 further drives the multiple bolt buckles 304 to move downward, so that the multiple bolt buckles 304 are again buckled on the periphery of the multiple bolt columns 306, coupling the two arc-shaped sampling barrels 201, making the two arc-shaped sampling barrels 201 not easy to open, so as to improve the stability of the two arc-shaped sampling barrels 201 during sampling.

[0048] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
