Description

Technical Field

[0001] The present invention relates to the technical field of mining geological rock sampling, and in particular to an automatic mining geological rock sampling device. Background Art

[0002] Mining geological rocks refer to various types of rocks related to the formation, occurrence and mining of ore deposits in the mining area. They are the product of geological action and are also important carriers or associated bodies of mineral resources. Rocks are composed of one or several minerals and natural glass, and are solid aggregates with stable shapes. Rocks composed of one mineral are called monomineral rocks, such as marble composed of calcite, quartzite composed of quartz, etc.; rocks composed of several minerals are called polymineral rocks, such as granite composed of minerals such as quartz, feldspar and mica, gabbro composed of basic plagioclase and pyroxene, etc. Liquids without a certain shape, such as oil, gases such as natural gas, and loose sand and mud, are not rocks. Rocks are one of the substances that make up the earth's crust and the main component of the earth's lithosphere. Among them, feldspar is the most important rock-forming component in the earth's crust, accounting for 60%, and quartz is the second most numerous ore.

[0003] In the field of mining geological exploration, geological rock sampling is the core link in the development of mineral resources. Its technical effectiveness directly affects the accuracy of resource assessment. In existing technologies, three key goals can be achieved by systematically analyzing parameters such as the mineral composition, hardness index, and fracture development characteristics of rock samples: first, accurately identify the lithology category (such as igneous rock, sedimentary rock, or metamorphic rock); second, clarify the spatial occurrence and occurrence of the ore body; more importantly, by detecting the grade value, spatial distribution law, and symbiotic combination relationship of target minerals in the ore (such as metal minerals, coal seams, or rare earth elements), a basis is provided for the precise delineation of the ore body boundary. However, in deep core drilling practice, conventional rotary drilling technology faces significant limitations. When encountering high-hardness rock formations (such as granite and quartzite), it is difficult to break through the high-strength barrier of the rock crystal structure by relying solely on the cutting force and shearing effect generated by the rotation of the drill bit. Although this rock breaking method based on continuous rotation is suitable for soft rocks (such as shale and clay) and medium-hard rock formations (such as sandstone and limestone), when dealing with extremely hard rocks with a Mohs hardness of ≥7, the drilling efficiency often drops sharply due to severe wear of the drill bit edge and insufficient rock-breaking energy, and even causes drill sticking accidents, ultimately affecting the integrity of deep core sampling and the reliability of exploration data. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides an automatic sampling device for mining geology and rock to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: An automatic sampling device for mining geological rocks includes a heavy-duty base, the top surface of which is provided with a mounting plate; an impact assembly, which is arranged on one side of the mounting plate and is used for impacting and crushing mining geological rocks, the impact assembly including: a limit frame, the limit frame is fixedly installed on one side of the mounting plate, the limit frame is fixedly installed on one side of the mounting plate, an impact rod is provided on one side of the mounting plate, the outer circular wall surface of the impact rod is movably sleeved with a spring, and is used for impacting the mining rock ground to crush it to form a sampling pit, an operating hole is provided on the bottom surface of the heavy-duty base; a driving assembly for moving the impact rod up and down is provided on one side of the mounting plate; a sampling assembly for taking out gravel from the sampling pit is provided on the top surface of the heavy-duty base; a penetration assembly for placing the sampling assembly into the pit is provided on the top surface of the heavy-duty base.

[0006] By adopting the above technical solution, through the setting of the impact rod, through the periodic lifting and lowering of the impact rod, and utilizing the energy storage and rebound of the spring, the impact rod causes the sampling head to repeatedly hit the ground, which can achieve rapid crushing of hard rock and prevent the traditional situation of encountering hard rock crushing difficulties during drilling.

[0007] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is that of an impeller, and the impeller is fixed with a link rod, and the interlocking structure is hinged on the base plate, is fixed with a backing pin on the interlocking structure, and the interlocking structure is hinged on the base plate, is fixed with a backing pin on the interlocking structure.

[0008] By adopting the above technical solution, through the impact rod set, when the staff takes samples of geological rocks in the mine, they first rotate the rotating column clockwise to drive the fixed ring and the pushing column to rotate, and then the pushing column will gradually approach the position of the force column during the clockwise rotation of the circle, and then the pushing column touches the surface of the force column and under the continuous rotation of the fixed ring and the pushing column, the pushing column will cause an extrusion force on the force column, through the extrusion of the pushing column, the pushing column will push the force column to drive the swing column, the linkage column and the rotating ring to rotate in a circle around the rotating column. Since the initial positions of the swing column and the linkage column are below the rotating ring and close to the limit frame, when the rotating ring drives the swing column and the linkage column to rotate, the positions of the swing column and the linkage column change in a circle, and then the positions of the swing column and the linkage column gradually rotate to the top surface of the rotating ring. In this process, the linkage column will pull the connecting rod to drive the connecting plate, the impact rod and the positioning ring to move upward, and the positioning ring When the cam is released, the spring is compressed, and the impact rod is moved away from the ground. When the swing column and the linkage column pull the connecting rod to rotate above the rotating ring, the rotating column drives the fixed ring and the pushing column to rotate away from the surface of the force column. At this time, the pushing column will release the push on the force column, and the rotational force on the rotating ring, the swing column and the linkage column will disappear. At the same time, the upward pulling force on the connecting rod, the connecting plate, the impact rod and the positioning ring will also disappear and release the compression of the spring. Then, the spring will drive the impact rod, the positioning ring and the connecting plate to rebound quickly. At the same time, the impact rod will drive the connecting plate to pull the connecting rod downward and drive the linkage column, the swing column and the rotating ring to rotate, and then the impact rod will hit the ground. Through the continuous rotation of the fixed ring and the pushing column and the rebound of the spring, the impact rod can continuously impact the mine rock ground, so as to crush the mine rock to form a sampling pit, so as to achieve the purpose of quickly obtaining surface samples.

[0010] By adopting the above technical solution, through the thickened spiral blades, when the staff uses the impact rod to open a hole in the rock ground of the mine, the fixed rod and the thickened spiral blades are placed in the pit, and then by using a three-phase AC asynchronous motor, the drive shaft of the three-phase AC asynchronous motor rotates clockwise to drive the fixed rod and the thickened spiral blades to rotate. Through the spiral rotation of the thickened spiral blades, the rock blocks on the inner wall of the pit can fall onto the thickened spiral blades, and then, with the spiral rotation of the fixed rod and the thickened spiral blades, the rock blocks in the sampling pit can be transported upward, thereby facilitating the delivery of the rock block samples in the pit to the ground, so that the staff can sample the mine rock samples deep underground.

[0012] By adopting the above technical solution, a mobile platform is set up. After the staff uses the impact rod to dig a hole on the mine surface, the reduction motor is used. The rotation of the drive shaft of the reduction motor will drive the first sprocket to rotate, and then the two first sprockets will rotate synchronously through the first chain transmission. Then the first sprocket will drive the rotating column and the second sprocket to rotate, and then the rotation of the two second sprockets will drive the limit frame transmission. At this time, the side of the second chain close to the heavy frame will drive the mobile platform, the three-phase AC asynchronous motor, the fixed rod and the thickened spiral blade to move downward when rotating, so as to facilitate the fixed rod and the thickened spiral blade to be placed in the hole for sampling.

[0013] Preferably, a mounting bracket is fixedly mounted on one side of the mounting plate, a driving motor is fixedly sleeved inside the mounting bracket, and a driving shaft of the driving motor is fixedly mounted on the rotating column.

[0014] By adopting the above technical solution, through the setting of the driving motor, the staff uses the driving motor, and the rotation of the driving shaft of the driving motor will drive the rotating column and the fixed ring to rotate, thereby facilitating the driving of the rotating column, the fixed ring and the pushing column to rotate, so as to provide rotational power to the rotating ring.

[0018] By adopting the above technical solution, through the setting of the first sliding platform and the second sliding platform, when the staff first uses the impact rod to drill a hole in the mine ground, the impact rod will pass through the operating hole and hit the ground. When the hole is drilled, the staff drives the second sliding platform to slide inside the sliding hole by pushing the operating hole, so that the impact rod can be moved away from the position of the opened hole. Then the heavy-duty frame is moved to drive the first sliding platform to move, and the fixed rod and the thickened spiral blade are moved to the position of the hole, so as to facilitate the thickened spiral blade to extend into the hole. At the same time, the mounting plate and the heavy-duty frame are moved to perform alternating operations of drilling holes and sampling in mine rocks.

[0023] In summary, the present invention mainly has the following beneficial effects: 1. The heavy-duty base, mounting plate, impact rod, spring, rotating column, rotating ring, swing column, linkage column, force-bearing column, fixed ring, push column, connecting rod and connecting plate provided in the present invention cooperate with each other to achieve high-frequency impact crushing of the rock surface of the mine, quickly form sampling holes, and efficiently obtain surface samples. By periodically raising and lowering the impact rod and utilizing the energy storage and rebound of the spring, the impact rod causes the sampling head to repeatedly impact the ground, which can achieve rapid crushing of hard rock and avoid the difficulty in crushing hard rock encountered in traditional drilling. 2. The invention uses thickened spiral blades to generate squeezing force on the rock on the inner wall of the pit during rotation, causing rock blocks to peel off and gather above the blades. The rotary torque overcomes the difference in rock hardness and is suitable for crushing soft to medium-hard rock layers, thus facilitating batch sampling of mining rocks in deep holes. 3. The present invention uses the rotation of the spiral blade to transport the exfoliated rock blocks upward, replacing the traditional manual digging or pulling method. The fixed rod serves as the axis support to ensure the stable rotation of the spiral blade and send the rock sample to the ground, thereby shortening the sampling time of the staff in the deep hole; 4. The present invention uses thickened spiral blades to squeeze and peel off the rocks on the inner wall of the pit during the lowering process, and transports the broken rock blocks upward to the ground. The transportation function of the thickened spiral blades reduces the pit cleaning steps, directly obtains deep samples, and realizes the integration of crushing and collection; 5. The present invention provides a first sliding platform and a second sliding platform. When the worker first uses the impact rod to drill a hole in the mine, the impact rod will pass through the operating hole and hit the ground. When the hole is drilled, the worker drives the second sliding platform to slide inside the sliding hole by pushing the operating hole, so that the impact rod can be moved away from the position of the hole to be drilled. Then, the heavy-duty frame is moved to drive the first sliding platform to move the fixed rod and the thickened spiral blade to the position of the hole to facilitate the thickened spiral blade to extend into the hole. At the same time, the installation plate and the heavy-duty frame are moved to perform alternating operations of drilling holes and sampling in the mine rock. 6. The present invention provides a ground cone, and when the heavy base is placed on the ground, the ground cone can be inserted into the ground, thereby stabilizing the heavy base.

Through the extrusion of the pushing column 15, the pushing column 15 will push the force column 13 to drive the swing column 11, the linkage column 12 and the rotating ring 10 to rotate in a circle around the rotating column 9. As the initial positions of the swing column 11 and the linkage column 12 are below the rotating ring 10 and close to the limit frame 3, when the rotating ring 10 drives the swing column 11 and the linkage column 12 to rotate, the positions of the swing column 11 and the linkage column 12 change in a circular manner, and then the positions of the swing column 11 and the linkage column 12 gradually rotate to the top surface of the rotating ring 10.

Then, the spring 6 will drive the impact rod 5, the positioning ring 21 and the connecting plate 18 to rebound quickly.

[0031] Working principle: Please refer to Figures 1-12As shown, through the provided impact rod 5, when the staff takes samples of the geological rocks in the mine, they first rotate the rotating column 9 clockwise to drive the fixed ring 14 and the pushing column 15 to rotate, and then the pushing column 15 gradually approaches the position of the force column 13 during the clockwise rotation of the circle, and then the pushing column 15 touches the surface of the force column 13 and under the continuous rotation of the fixed ring 14 and the pushing column 15, the pushing column 15 will cause an extrusion force on the force column 13. Through the extrusion of the pushing column 15, the pushing column 15 will push the force column 13 to drive the swing column 11, the linkage column 12 and the rotating ring 10 to rotate in a circular motion around the rotating column 9. The swing column 11 and the linkage column 12 rotate in a circle. Since the initial positions of the swing column 11 and the linkage column 12 are below the rotating ring 10 and close to the limit frame 3, when the rotating ring 10 drives the swing column 11 and the linkage column 12 to rotate, the positions of the swing column 11 and the linkage column 12 change in a circle, and then the positions of the swing column 11 and the linkage column 12 gradually rotate to the top surface of the rotating ring 10. During this process, the linkage column 12 will pull the connecting rod 16 to drive the connecting plate 18, the impact rod 5 and the positioning ring 21 to move upward. When the positioning ring 21 moves upward, it will compress the spring 6. This action can keep the impact rod 5 away from the ground. When the swing column 11 and the linkage column 12 When the connecting rod 16 is pulled and rotated to the top of the rotating ring 10, the rotating column 9 drives the fixed ring 14 and the pushing column 15 to rotate away from the surface of the force-bearing column 13. At this time, the pushing column 15 will release the push on the force-bearing column 13, and then the rotational force on the rotating ring 10, the swing column 11 and the linkage column 12 will disappear. At the same time, the upward pulling force on the connecting rod 16, the connecting plate 18, the impact rod 5 and the positioning ring 21 will also disappear and release the compression of the spring 6. Then, the spring 6 will drive the impact rod 5, the positioning ring 21 and the connecting plate 18 to rebound quickly. At the same time, the impact rod 5 will drive the connecting plate 18 to pull the connecting rod 16 downward and drive The linkage column 12, the swing column 11 and the rotating ring 10 rotate, and then the impact rod 5 will hit the ground. Through the continuous rotation of the fixed ring 14 and the push column 15 and the rebound of the spring 6, the impact rod 5 is facilitated to continuously impact the mine rock ground, so as to crush the mine rock to form sampling pits, so as to achieve the purpose of quickly obtaining surface samples. Through the setting of the impact rod 5, through the periodic lifting of the impact rod 5, and using the energy storage and rebound of the spring 6, the impact rod 5 makes the sampling head repeatedly hit the ground, which can achieve rapid crushing of hard rock and prevent the traditional situation of hard rock crushing difficulties encountered in drilling.

[0032] By setting the thickened spiral blade 27, after the staff uses the impact rod 5 to open a hole in the rock ground of the mine, the fixed rod 26 and the thickened spiral blade 27 are placed in the pit, and then by using the three-phase AC asynchronous motor 41, the drive shaft of the three-phase AC asynchronous motor 41 rotates clockwise to drive the fixed rod 26 and the thickened spiral blade 27 to rotate. Through the spiral rotation of the thickened spiral blade 27, the rock blocks on the inner wall of the pit can fall onto the thickened spiral blade 27, and then, with the spiral rotation of the fixed rod 26 and the thickened spiral blade 27, the rock blocks in the sampling pit can be transported upward, thereby facilitating the delivery of the rock block samples in the pit to the ground, so that the staff can sample the mine rock samples deep underground.

[0033] Through the provided movable platform 38, when the staff uses the impact rod 5 to drill the pit on the mine ground, by using the reduction motor 35, the rotation of the drive shaft of the reduction motor 35 will drive the first sprocket 36 to rotate, and then the two first sprockets 36 will rotate synchronously through the first chain 37 chain transmission, and then the first sprocket 36 will drive the rotating column 29 and the second sprocket 32 ​​to rotate, and then the rotation of the two second sprockets 32 will drive the limit frame 3 to transmit, at this time, the side of the second chain 33 close to the heavy frame 25 will drive the movable platform 38, the three-phase AC asynchronous motor 41, the fixed rod 26 and the thickened spiral blade 27 to move downward when rotating, so as to facilitate the fixed rod 26 and the thickened spiral blade 27 to be placed in the pit for sampling.

[0034] By setting the first sliding platform 46 and the second sliding platform 47, when the staff first uses the impact rod 5 to drill a hole in the mine ground, the impact rod 5 will pass through the operating hole 7 and hit the ground. When the hole is drilled, the staff drives the second sliding platform 47 to slide inside the sliding hole 48 by pushing the operating hole 7, so that the impact rod 5 can be moved away from the position of the opened hole. Then the heavy-duty frame 25 is moved to drive the first sliding platform 46 to move, and the fixed rod 26 and the thickened spiral blade 27 are moved to the position of the hole, so as to facilitate the thickened spiral blade 27 to extend into the hole. At the same time, the mounting plate 2 and the heavy-duty frame 25 are moved to perform alternating operations of drilling holes and sampling in mine rocks.
