Description

Technical Field

[0001] This invention relates to the field of geological sampling technology, specifically to a geological mapping and sampling device that facilitates sample preservation. Background Technology

[0002] During geological exploration, samples are usually taken for testing purposes so that they can be brought back to the laboratory for component analysis. This requires the use of sampling equipment. The commonly used sampling equipment for geological and mineral exploration and mapping is a drilling rig, which is used to drill holes and collect samples in conjunction with a sampling drill bit.

[0003] A geological exploration sampling device, such as one disclosed in CN210119367U, includes a base plate. A through hole is located in the middle of the upper surface of the base plate. Support rods are fixedly connected to both sides of the upper surface of the base plate. A connecting groove is provided on the upper surface of each support rod. A horizontal rod is rotatably connected to the inner surface of the connecting groove via a support shaft. A vertical rod is hinged to the inner end of the horizontal rod via a first hinge shaft. A sampling cylinder is hinged to the lower surface of the vertical rod via a second hinge shaft. The lower surface of the sampling cylinder has a tapered cross-section. The outer surface of the sampling cylinder is slidably connected to the inner surface of the through hole. A threaded through hole is located in the middle of the upper end of the sampling cylinder. The inner surface of the threaded through hole... The threaded connection has a threaded head, and a push plate is fixedly connected to the lower surface of the threaded head. This greatly improves the convenience and stability of use. In existing soil testing, a certain amount of soil is first dug up, then brought back to the laboratory, and a certain amount of water is added and stirred to test the acidity and alkalinity of the soil sample. However, existing soil sampling devices usually require soil sampling first, and then the soil is taken out of the sampling tube and taken to the laboratory for testing or on-site testing. It is not convenient to mix the sampled soil with water, making the operation inconvenient and causing trouble for actual testing. In addition, when the sampling tube is drilled into the soil for sampling, some soil will adhere to the outer wall of the sampling tube, which will also cause inconvenience for subsequent cleaning and sampling.

[0004] Therefore, a geological mapping sampling device that facilitates sample preservation is proposed to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a geological surveying and sampling device that facilitates sample preservation, thereby solving the problem that the device requires soil sampling before testing, which is inconvenient to mix the sampled soil with water, making the operation inconvenient and causing trouble for actual testing.

The collecting tank is threadedly connected to the threaded sleeves, the vertical groove passes through the mounting plate and communicates with the threaded sleeves, and an agitator is fixedly connected to the lower outer part of the rotating rod.

[0017] By adopting the above technical solution, the rotating shaft will also drive the main synchronous pulley to rotate. The main synchronous pulley drives the secondary synchronous pulley to rotate via a toothed belt. The secondary synchronous pulley drives the rotating rod and the stirring rod to rotate. After being guided by the guide block, the soil and water enter the collection tank.

[0018] Preferably, a baffle is fixedly connected to the outer side of the slide rod, the baffle is located between the sealing block and the chassis, the baffle is located outside the mounting plate, and a through hole is opened in the middle of the guide block, and the sealing block is engaged with the through hole.

[0020] Preferably, a spring is fixedly installed inside the fixed cylinder, the top end of the spring is fixedly connected to the top rod, and the bottom end of the spring is fixedly connected to the inner bottom surface of the fixed cylinder. The collection tank includes an upper part and a lower part, the inner diameter of the upper part is larger than the inner diameter of the lower part, and the base plate is in contact with the lower inner wall of the collection tank.

[0021] By adopting the above technical solution, as the soil enters, the chassis is pressed down by the gravity of the soil and water. The chassis drives the top rod to press down, the top rod slides into the fixed cylinder and compresses the spring, and the chassis descends, causing the sliding rod and sealing block to descend.

[0022] Preferably, the cleaning assembly includes a side rod rotatably connected to the outside of the sampling cylinder, the side rod being fixedly connected to the mounting plate, a vertical rod being fixedly connected to the bottom of the side rod, and a squeezing block being uniformly fixedly connected to the side of the vertical rod near the sampling cylinder.

[0023] By adopting the above technical solution, the side rod will descend when the mounting plate descends. The side rod is rotatably installed with the sampling cylinder and will not obstruct the rotation of the sampling cylinder.

[0024] Preferably, the inner side of the fixed frame is fixedly connected with two fixed strips in parallel, the top of the fixed strips is fixedly connected with a limit rod, and the outer sides of the two limit rods are rotatably connected with the same annular component.

[0025] By adopting the above technical solution, the side rod drives the vertical rod and the extrusion block to descend, and the extrusion block extrudes the inclined surface of the fixed block, causing the fixed block and the ring part to rotate at a certain angle.

The top and bottom surfaces of the fixing blocks are both provided with inclined surfaces.

[0027] By adopting the above technical solution, the annular component acts on the torsion spring, and the limiting rod is used to assist the rotation of the annular component. When the extrusion block separates from the fixed block, the elastic force of the torsion spring drives the annular component to rotate and reset, and the annular component will scrape the sampling cylinder part by reciprocating rotation.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. By setting up the sampling components, the operator moves the fixed frame to the usage position and rotates the positioning screw into the soil for easy positioning of the device. The drive motor and servo motor are then activated. The drive motor rotates the shaft, which in turn rotates the screw conveyor. The servo motor drives the gears, which in turn rotate the sampling cylinder. The electric push rod lowers the mounting plate and sampling cylinder, causing the sampling cylinder to break up the soil. The rotating screw conveyor lifts the soil for collection, which enters the central trough. The shaft then rotates the crushing blades, which break up the soil. The soil then enters the vertical trough through an inclined chute. The collection tank is threaded onto the inside of the threaded sleeve, with the fixed cylinder fitting against the inner bottom surface of the collection tank. The baffle plate fits against the bottom surface of the mounting plate. The operator injects water through the water inlet pipe. The shaft also drives the main synchronous pulley to rotate, which in turn drives the secondary synchronous pulley via a toothed belt. The secondary synchronous pulley then drives the rotating rod and agitator rod to rotate. After being guided by the guide block, the soil and water enter the collection tank, which is located at the top of the chassis. The stirring rod acts as a stirrer. As the soil enters, the chassis is pressed down by the gravity of the soil and water. The chassis drives the top rod to press down, and the top rod slides into the fixed cylinder and compresses the spring. The chassis descends, causing the sliding rod and the sealing block to descend until the sealing block blocks the guide block, allowing the soil to enter the collection tank in a measured amount. At this point, the soil sampling is completed. The electric push rod is activated to retract, and the electric push rod drives the mounting plate and sampling cylinder to rise and reset. The operator rotates the collection tank to unscrew it from the threaded sleeve. When the chassis is located at the top of the collection tank, the inner diameter of the upper part of the collection tank is larger than the diameter of the chassis, allowing the water and soil to flow into the interior of the collection tank. This facilitates the removal of the mixed sample and solves the problem that the device requires soil sampling before testing, which is inconvenient to mix the sampled soil with water, making operation more inconvenient and causing trouble for actual testing.

[0030] 2. By setting up a cleaning component, the side rod will descend when the mounting plate descends. The side rod is rotatably mounted to the sampling cylinder without obstructing its rotation. The side rod drives the vertical rod and the squeezing block to descend. The squeezing block squeezes the inclined surface of the fixed block, causing the fixed block and the ring component to rotate at a certain angle. The ring component acts on the torsion spring, and the limit rod is used to assist the rotation of the ring component. When the squeezing block separates from the fixed block, the elastic force of the torsion spring causes the ring component to rotate back to its original position. The top and bottom surfaces of the fixed block are both inclined, which will not obstruct the reset of the squeezing block. This allows the ring component to reciprocate and scrape the sampling cylinder, thereby reducing the amount of soil adhering to the outside of the sampling cylinder and improving the sampling effect.

[0053] The top of the rotating rod 614 passes through the mounting plate 5 and is fixedly connected to a timing pulley 615.

The collection tank 9 is threadedly connected to the threaded sleeve 619. The vertical groove 611 passes through the mounting plate 5 and is connected to the threaded sleeve 619. The lower outer part of the rotating rod 614 is fixedly connected to an agitator 620.

[0054] A sealing block 623 is fixedly connected to the lower outer side of the slide rod 618, and a top rod 626 is fixedly connected to the bottom of the chassis 622. A fixing cylinder 624 is slidably connected to the outer side of the top rod 626.

[0055] A baffle plate 621 is fixedly connected to the outside of the slide rod 618. The baffle plate 621 is located between the sealing block 623 and the chassis 622. The baffle plate 621 is located outside the mounting plate 5. A through hole is opened in the middle of the guide block 617. The sealing block 623 is engaged with the through hole.

[0056] A spring 625 is fixedly installed inside the fixed cylinder 624. The top of the spring 625 is fixedly connected to the top rod 626, and the bottom of the spring 625 is fixedly connected to the inner bottom surface of the fixed cylinder 624. The collection tank 9 includes an upper part and a lower part. The inner diameter of the upper part is larger than that of the lower part. The base 622 is in contact with the lower inner wall of the collection tank 9.

[0057] Example 1: As Figure 4 - Figure 11As shown, the operator moves the fixed frame 1 to the usage position and rotates the positioning screw 8 into the soil for auxiliary positioning of the device. The drive motor 61 and servo motor 67 are started. The drive motor 61 drives the rotating shaft 64 to rotate, the rotating shaft 64 drives the spiral conveyor rod 66 to rotate, the servo motor 67 drives the gear 68 to rotate, the gear 68 drives the sampling cylinder 63 to rotate, the electric push rod 4 drives the mounting plate 5 and the sampling cylinder 63 to descend, the sampling cylinder 63 breaks the soil, the spiral conveyor rod 66 rotates to drive the soil to rise and be collected, the soil enters the central trough, the rotating shaft 64 drives the crushing blade 65 to rotate, and the crushing blade 65 crushes the soil.

[0058] Next, the soil enters the vertical trough 611 through the inclined trough 610. The collection tank 9 is threadedly installed inside the threaded sleeve 619. The fixed cylinder 624 is in contact with the inner bottom surface of the collection tank 9. The baffle 621 is in contact with the bottom surface of the mounting plate 5. The operator injects water through the water inlet pipe 612. The rotating shaft 64 also drives the main synchronous pulley 613 to rotate. The main synchronous pulley 613 drives the secondary synchronous pulley 615 to rotate through the toothed belt 616. The secondary synchronous pulley 615 drives the rotating rod 614 and the stirring rod 620 to rotate. The soil and water are guided by the guide block 617 and then enter the collection tank 9.

[0059] Located at the top of the chassis 622, the stirring rod 620 plays a stirring role. As the soil enters, the chassis 622 is pressed down by the gravity of the soil and water. The chassis 622 drives the top rod 626 to press down. The top rod 626 slides into the fixed cylinder 624 and compresses the spring 625. The chassis 622 descends, driving the sliding rod 618 and the sealing block 623 to descend until the sealing block 623 blocks the guide block 617, so that the soil enters the collection tank 9 in a measured amount. At this time, the soil sampling is completed.

[0060] The electric push rod 4 is activated to retract, which drives the mounting plate 5 and the sampling cylinder 63 to rise and reset. The operator rotates the collection tank 9 to unscrew it from the threaded sleeve 619. When the base plate 622 is above the collection tank 9, the inner diameter of the upper part of the collection tank 9 is larger than the diameter of the base plate 622, allowing water and soil to flow into the interior of the collection tank 9. This facilitates the removal of the mixed sample, solving the problem that the device requires soil sampling before testing, which is inconvenient to mix the sampled soil with water, making operation difficult and causing trouble for actual testing.

[0061] The cleaning assembly 7 includes a side rod 71 rotatably connected to the outside of the sampling cylinder 63. The side rod 71 is fixedly connected to the mounting plate 5. A vertical rod 72 is fixedly connected to the bottom of the side rod 71. An extrusion block 73 is evenly fixedly connected to the side of the vertical rod 72 near the sampling cylinder 63.

[0062] The inner side of the fixed frame 1 is fixedly connected with two fixed strips 74 in parallel. The top of the fixed strips 74 is fixedly connected with a limit rod 75. The outer sides of the two limit rods 75 are rotatably connected with the same ring piece 76.

[0063] Two fixing bars 74 are fixedly installed with torsion springs 77 at their tops. A limiting rod 75 is located in the inner ring of the torsion springs 77. The top of the torsion springs 77 is fixedly connected to the annular piece 76. Fixing blocks 78 are symmetrically fixedly connected to the outer side of the annular piece 76. The top and bottom surfaces of the fixing blocks 78 are both provided with inclined surfaces.

[0064] Example 2: Figure 12 - Figure 14 As shown, when the mounting plate 5 descends, it will drive the side rod 71 to descend. The side rod 71 is rotatably mounted with the sampling cylinder 63, which will not hinder the rotation of the sampling cylinder 63. The side rod 71 drives the vertical rod 72 and the extrusion block 73 to descend. The extrusion block 73 extrudes the inclined surface of the fixing block 78, causing the fixing block 78 and the ring member 76 to rotate at a certain angle. The ring member 76 acts on the torsion spring 77.

[0065] The limiting rod 75 is used to assist the rotation of the annular part 76. When the squeezing block 73 separates from the fixing block 78, the elastic force of the torsion spring 77 drives the annular part 76 to rotate and reset. The top and bottom surfaces of the fixing block 78 are both provided with inclined surfaces, which will not block the reset of the squeezing block 73. This allows the annular part 76 to reciprocate and scrape the sampling cylinder 63, thereby reducing the situation where soil adheres to the outside of the sampling cylinder 63 and improving the sampling effect.

[0066] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, the operator starts the drive motor 61 and servo motor 67. The drive motor 61 drives the rotating shaft 64 to rotate, which in turn drives the screw conveyor 66 to rotate. The servo motor 67 drives the gear 68 to rotate, which in turn drives the sampling cylinder 63 to rotate. The electric push rod 4 drives the mounting plate 5 and the sampling cylinder 63 to descend, and the sampling cylinder 63 breaks the soil. The rotating screw conveyor 66 drives the soil to rise and be collected. The soil enters the central trough. The rotating shaft 64 drives the crushing blade 65 to rotate, and then the soil enters the vertical trough 611 through the inclined trough 610. The operator injects water through the water pipe 612. After the soil and water are guided by the guide block 617, they enter the collection tank 9, which is located on top of the chassis 622. The stirring rod 620 plays a stirring role, and the soil... As soil enters, the chassis 622 is pressed down by the gravity of the soil and water until the sealing block 623 blocks the guide block 617, allowing the soil to enter the collection tank 9 in a measured amount. At this point, soil sampling is completed. The electric push rod 4 is activated to retract, and the electric push rod 4 drives the mounting plate 5 and the sampling cylinder 63 to rise and reset. The operator rotates the collection tank 9 to unscrew it from the threaded sleeve 619. When the chassis 622 is above the collection tank 9, water and soil flow into the interior of the collection tank 9, facilitating the removal of the mixed sample. When the mounting plate 5 descends, it drives the side rod 71 to descend, and the squeezing block 73 squeezes the inclined surface of the fixing block 78. The annular part 76 reciprocates and scrapes the sampling cylinder 63, thereby reducing the amount of soil adhering to the outside of the sampling cylinder 63 and improving the sampling effect.
