Description

Technical Field

[0001] This invention relates to the field of sampling equipment technology, specifically to a drilling sampling device for geological and mineral exploration. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters.

[0003] CN118481624A discloses a geological exploration drilling and sampling device, including a base and a drilling mechanism. The drilling mechanism includes a support assembly mounted on the base, a drive assembly mounted on the support assembly, and a drill rod connected to the output end of the drive assembly. The drill rod drills into the ground, and a sampling assembly is located at the end of the drill rod away from the drive assembly. The sampling assembly includes a sampling tube that is telescopically disposed within the cavity of the drill rod. A sealing assembly corresponding to the sampling tube is located at the bottom end of the drill rod. The sealing assembly includes several partition blocks telescopically disposed within the drill rod, with the top ends of the partition blocks detachably connected to the bottom end of the sampling tube. This application provides a fast and efficient sampling process with minimal disturbance to the formation. The sampling process does not break up or mix the formation in the target area, and it preserves the hierarchical structure of the sample after sampling. This ensures a high degree of correspondence between the sample and the actual structure of the formation, providing more detailed and accurate data support for geological research.

[0004] In the existing technology, the drilling mechanism and other components in the above-mentioned device improve the sampling efficiency and reduce the disturbance to the formation. However, after the sampling is completed, the staff needs to take out the inner tube in the sampling tube and work with another staff member to tilt the inner tube in order to collect the sample obtained in the inner tube. However, during the tilting process, since the sample has filled the inner tube, the inner tube is heavy. Sampling work for a long time will consume the staff’s physical strength, which will lead to a decrease in sampling efficiency. Moreover, if the staff continues to sample when they are physically exhausted, the inner tube may fall to the ground, which will not only pose a safety hazard to the staff, but also damage the inner tube structure.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-14 As shown, this application provides a drilling and sampling device for geological and mineral exploration, including a frame 1, an outer tube 3, and an inner tube 4; a movable chamber 11 is fixedly connected to the frame 1; a movable lead screw 12 is rotatably connected inside the movable chamber 11, and the device further includes: Drilling mechanism 2, mounted on frame 1, is used to drive inner tube 4 and outer tube 3 for exploration and sampling work; Auxiliary mechanism 5, mounted on frame 1, is used for removing the sample from inner tube 4; The lifting mechanism 6 is located at the top of the frame 1 and is used to remove the inner tube 4 from the outer tube 3; The fixing mechanism 7 is located below the auxiliary mechanism 5 and is used to fix and move the inner tube 4; The collection mechanism 8 is located below the frame 1 and is used to collect the sample in the inner tube 4; The inner tube 4 is placed into the outer tube 3, and the drilling mechanism 2 is connected to the outer tube 3. Sampling is then performed. After the work is completed, the lifting mechanism 6 is driven to pull the inner tube 4 out of the outer tube 3. Then, the fixing mechanism 7 and the auxiliary mechanism 5 are used to fix the inner tube 4. After fixing, the fixing mechanism 7 is driven to move, so that the inner tube 4 is tilted, thereby taking out the sample from the inner tube 4. During operation, the inner tube 4 is placed into the outer tube 3, and then the drilling mechanism 2 is driven to connect with the outer tube 3. Sampling is then performed. After sampling, the drilling mechanism 2 is driven away from the outer tube 3, and then the lifting mechanism 6 is driven to descend into the outer tube 3 to pull the inner tube 4 out of the outer tube 3. During the pulling process, the fixing mechanism 7 and the auxiliary mechanism 5 are driven to work. After the inner tube 4 is completely pulled out, the fixing mechanism 7 and the auxiliary mechanism 5 are used to fix the inner tube 4. After fixing, the fixing mechanism 7 is driven to move, causing the inner tube 4 to tilt. Then, the collection mechanism 8 is used to take out the sample from the inner tube 4.

[0023] like Figures 3-5As shown, the mobile compartment 11 is provided in two sets, both located on both sides of the frame 1; the fixing mechanism 7 includes a fixed base 71; a threaded block 76 is fixedly connected to the bottom of the fixed base 71; the threaded block 76 is threadedly connected to the moving lead screw 12; a fixed lead screw 711 is rotatably connected inside the fixed base 71; a drive plate 712 is threadedly connected to the fixed lead screw 711; a connecting column 72 is fixedly connected to the drive plate 712; the connecting column 72 passes through the fixed base 71; a rotating plate 721 is fixedly connected to the end of the connecting column 72 away from the drive plate 712; a fixed plate 73 is rotatably connected to the rotating plate 721; the fixed base 71 is provided in two sets; the collecting mechanism 8 includes a collecting base 81; the collecting base 81 is provided with... Four sets are provided; a collecting screw 82 is rotatably connected inside the collecting base 81; a connecting plate 821 is threadedly connected to the collecting screw 82; a collecting arc plate 83 is fixedly connected to the connecting plate 821; two sets of collecting arc plates 83 are provided, both located on both sides of the frame 1; a connecting rack 75 is fixedly connected to the side wall of the fixed base 71; a drive gear 85 is rotatably connected to the side wall of the collecting base 81; the output end of the drive gear 85 is fixedly connected to the input end of the collecting screw 82; a synchronous pulley 851 is fixedly connected to the drive gear 85; the connecting rack 75 and the drive gear 85 are movably meshed; a cleaning brush 13 is fixedly connected to the side wall of the moving chamber 11; the cleaning brush 13 abuts against the collecting arc plate 83; the collecting arc plate 83 is inclined. During operation, the inner tube 4 is removed from the outer tube 3 using the lifting mechanism 6. Then, the fixing screw 711 inside the fixed base 71 is driven to rotate. During rotation, the driving plate 712 on the fixing screw 711 moves towards the inner tube 4. Simultaneously, the rotating plate 721 and the fixing plate 73 on the rotating plate 721 move closer to the inner tube 4, and the fixing plate 73 clamps and fixes the inner tube 4. At the same time, the auxiliary mechanism 5 above also fixes the inner tube 4. Once both ends of the inner tube 4 are fixed, the moving screw 12 inside the moving chamber 11 is driven to rotate. When the moving screw 12 rotates, it passes through the threaded block... 76 drives the fixed base 71 to move, causing the inner tube 4 to tilt. While the fixed base 71 moves, the upper auxiliary mechanism 5 remains stationary. Therefore, as the fixed base 71 moves, the fixed inner tube 4 gradually tilts, and the fixing plate 73 used to clamp the inner tube 4 also rotates accordingly. When the fixed base 71 moves, the connecting rack 75 below the fixed base 71 meshes with the drive gear 85 on the side wall of the collecting base 81, driving the drive gear 85 to rotate. The collecting base 81 has four sets of drive gears, and two sets of drive gears 85 are respectively located on both sides of the frame 1. Two sets of connecting racks 75 are used, while the other two sets of collecting screws 82 are driven by synchronous pulleys 851. When the connecting racks 75 mesh with the driving gears 85, the continuous movement of the fixed base 71 will drive the driving gears 85 to rotate. When the driving gears 85 rotate, one end drives the collecting screws 82 in the collecting base 81 to rotate, and the other end drives the synchronous pulleys 851 to rotate. The synchronous pulleys 851 then drive the other two sets of collecting screws 82 to rotate, thereby driving the collecting arc plates 83 on the collecting screws 82 to move. When the fixed base 71 moves toward the collecting arc plates 83, the collecting arc plates... Driven by the collecting screw 82, the 83 gradually closes, forming a semi-circular base plate. At the same time, when the fixed base 71 moves, the inner tube 4 is tilted. In this state, the sample in the inner tube 4 will fall onto the collecting arc plate 83 and be guided by the collecting arc plate 83 to avoid the sample falling vertically and causing damage. After collection is completed, the fixed base 71 drives the inner tube 4 to move back. During the movement back, the collecting arc plate 83 also retracts at the same time. When it retracts, the collecting arc plate 83 will come into contact with the cleaning brush 13. The cleaning brush 13 will clean the sample remaining on the collecting arc plate 83 to avoid confusion during the next sampling.

[0024] like Figure 6As shown, the auxiliary mechanism 5 includes an auxiliary base 51; the side wall of the auxiliary base 51 is rotatably connected to a rotating shaft 53; the auxiliary base 51 is rotatably connected to the frame 1 via the rotating shaft 53; an auxiliary lead screw 52 is rotatably connected inside the auxiliary base 51; a slider 521 is threaded onto the auxiliary lead screw 52; a clamping base 54 is fixedly connected to the slider 521; a second rotating column 543 is rotatably connected to the clamping base 54; a striking column 544 is slidably connected to the clamping base 54; a first rotating column 542 is rotatably connected to the striking column 544; a clamping plate 55 is fixedly connected to the side wall of the clamping base 54; the clamping plate 55... A sliding column 551 and a worm gear 56 are rotatably connected in the middle of the 5-section; the sliding column 551 abuts against the inner tube 4; the input end of the worm gear 56 is fixedly connected to the output end of the sliding column 551; a worm wheel 57 is rotatably provided on the side wall of the clamping base 54; the worm wheel 57 is meshed with the worm gear 56; a drive column 571 is rotatably connected to the worm wheel 57; a connecting rod 58 is rotatably connected to the drive column 571; a triangular connecting rod 59 is rotatably connected to the end of the connecting rod 58 away from the drive column 571; the middle part of the triangular connecting rod 59 is rotatably connected to a rotating column 543, and the other end is rotatably connected to a rotating column 542; two sets of auxiliary bases are provided in the auxiliary base 51. During operation, when the lifting mechanism 6 removes the inner tube 4 from the outer tube 3, it raises the inner tube 4 to the height of the auxiliary base 51. Then, it drives the auxiliary lead screw 52 inside the auxiliary base 51 to rotate, and the lower fixed lead screw 711 also rotates simultaneously. As the auxiliary lead screw 52 rotates, it drives the slider 521 and the clamping base 54 to move towards the inner tube 4. The inner tube 4 is then clamped and fixed by the sliding column 551 within the clamping plate 55 on the clamping base 54. At this point, the inner tube 4 is double-fixed by the fixing plate 73 and the clamping plate 55. Subsequently, the fixed base 71 is driven to move. When moved, the inner tube 4 tilts. Simultaneously, as the tilt angle increases, the inner tube 4 is pulled by the fixed base 71. When pulled, the inner tube 4 is both limited by the clamping plate 55 and held by the sliding column 551, as it is fixed by the sliding column 551. Furthermore, the movement of the inner tube 4 while being held also causes the sliding column 551 to rotate. When the sliding column 551 rotates, it drives the worm gear 56 on one side to rotate, which in turn drives the worm wheel 57 to rotate. When the worm wheel 57 rotates, the drive pin 57 on the worm wheel 57... 1. The connecting rod 58 swings, which in turn causes one end of the triangular connecting rod 59 to swing. The middle of the triangular connecting rod 59 is limited by the rotating column 543. When the triangular connecting rod 59 swings, it will reciprocate. During the reciprocating motion, the other end of the triangular connecting rod 59 will drive the rotating column 542 and the striking column 544 to reciprocate. During the reciprocating motion of the striking column 544, it will collide with the clamped inner tube 4. Thus, during the time that the fixed base 71 moves, the striking column 544 will produce regular impacts on the inner tube 4. Under the impact, it will increase... The sample falling into the inner tube 4 is facilitated by the auxiliary mechanism 5, which, together with the fixing mechanism 7, fixes the other end of the inner tube 4. After fixing, as the fixing base 71 moves, the inner tube 4 drives the sliding column 551 and the worm gear 56 to rotate. At the same time, the connecting rod 58 and the triangular connecting rod 59 drive the striking column 544 to move back and forth. During the back and forth movement, the striking column 544 is impacted, thereby accelerating the falling of the sample into the inner tube 4 and preventing the sample from remaining in the inner tube 4. At the same time, the sliding groove 541 prevents the striking column 544 from deviating during movement.

[0025] like Figures 3-5 As shown, the clamping base 54 has a sliding groove 541; the bottom of the striking column 544 is slidably connected to the sliding groove 541; the striking column 544 is movably abutting against the inner tube 4. During operation, when the striking column 544 moves, its bottom is connected to the slide groove 541 and is limited by the slide groove 541. The limiting effect of the slide groove 541 can prevent the striking column 544 from deviating.

[0026] like Figures 8-12As shown, a threaded pipe 31 is fixedly connected to the end of the outer pipe 3; the outer pipe 3 is connected to the drilling mechanism 2 via the threaded pipe 31; the drilling mechanism 2 is movably mounted on the frame 1; a limiting sleeve 32 is fixedly connected to the inner wall of the outer pipe 3; a limiting base 33 is fixedly connected to the bottom of the outer pipe 3; a limiting block 42 is fixedly connected to the inner wall of the inner pipe 4; the limiting block 42 is movably engaged with the limiting sleeve 32; a bottom groove 45 is provided at the bottom of the inner pipe 4; the bottom groove 45 is movably engaged with the limiting base 33. During operation, the inner tube 4 is inserted into the outer tube 3, and the bottom groove 45 of the inner tube 4 is engaged with the limiting base 33 at the bottom of the outer tube 3. At the same time, the limiting block 42 on the inner tube 4 is engaged with the limiting sleeve 32. The setting of the limiting base 33 and the limiting sleeve 32 can prevent the inner tube 4 from shaking inside the outer tube 3. After installation, the drilling mechanism 2 is connected to the threaded pipe 31 to realize the drilling work. After the work is completed, the drilling mechanism 2 is disconnected from the threaded pipe 31, and the drilling mechanism 2 is moved to the left to avoid affecting the subsequent lifting of the inner tube 4.

[0027] like Figure 13 and Figure 14 As shown, the lifting mechanism 6 includes a lifting wheel 61 and a lifting head 62; the lifting wheel 61 is disposed on the top of the frame 1; the lifting head 62 and the lifting wheel 61 are connected by a rope; a lifting base 43 is fixedly connected to the top of the inner tube 4; a lifting column 44 is fixedly connected to the lifting base 43; a pull plate 442 is fixedly connected to the end of the lifting column 44 away from the lifting base 43; a sliding buckle 441 is slidably connected to the lifting column 44; an inner groove 621 is opened in the middle of the lifting head 62; a telescopic spring 622 is provided on the side wall of the lifting head 62; a clamping knife 623 is fixedly connected to the end of the telescopic spring 622 away from the lifting head 62; the clamping knife 623 is slidably disposed inside the lifting head 62; the clamping knife 623 is in movable contact with the sliding buckle 441 and the pull plate 442; a pull ring 624 is fixedly connected to the top of the lifting head 62. During operation, after drilling is completed, the lifting head 62 is driven to descend using the lifting wheel 61 and pull ring 624, allowing it to insert into the lifting column 44. During insertion, the cutter 623 inside the lifting head 62 contacts the pull plate 442. As the lifting head 62 descends, the cutter 623 is pressed into the lifting head 62 by the pull plate 442, thus passing through the pull plate 442, causing the right-angled end of the cutter 623 to abut against the pull plate 442. Then, the lifting head 62 is driven to rise, and using the engagement of the cutter 623 and the pull plate 442, the inner tube 4 is pulled out from the outer tube 3. After extraction, sampling begins. After sampling is completed, the lifting head 62 is driven to rise again. The lifting head 62 descends, allowing the inner tube 4 to insert into the outer tube 3. Once fully inserted, the lifting column 44 is inside the lifting head 62. The lifting head 62 is then driven to descend again. During descent, the cutter head contacts and is squeezed by the sliding buckle 441. The hand-held cutter 623 then reaches below the sliding buckle 441. Since the sliding buckle 441 is double-sidedly inclined, after the hand-held cutter 623 reaches below the sliding buckle 441, the lifting head 62 is pulled again. The hand-held cutter 623 is then squeezed by both the sliding buckle 441 and the pull plate 442. The lifting head 62 then disengages from the lifting column 44, and drilling operations can then be performed using the drilling mechanism 2.

[0028] like Figure 1 As shown, a fixed motor 74 is fixedly connected to the side wall of the fixed base 71; the fixed lead screw 711 is driven by the fixed motor 74; a moving motor 14 is fixedly connected to the side wall of the moving compartment 11; the moving lead screw 12 is driven by the moving motor 14; the fixed motor 74 and the moving motor 14 are shaft motors. During operation, the shaft motor is a commonly used working motor on the market, some of which are not shown in the figure.

[0029] like Figure 1 As shown, the moving lead screw 12, the fixed lead screw 711, the auxiliary lead screw 52, ​​and the collecting lead screw 82 are all trapezoidal lead screws; During operation, the trapezoidal lead screw can convert rotary motion into linear motion, making the operation more convenient.
