Description

Technical Field

[0001] This invention belongs to the field of soil sampling technology, specifically relating to a geological soil sampling device. Background Technology

[0002] Soil sampling is a fundamental step in geological exploration, agriculture, forestry, horticulture, and environmental monitoring. A common field procedure involves inserting a sampling tube into the soil using a vibratory pump, and then using an external puller to overcome sidewall friction and remove the tube. This procedure suffers from several common problems during sampling. The processes of burying and pulling up the soil rely on different tools and multiple people working together, resulting in dispersed operations and high labor intensity; the sampling tube is prone to swaying, increasing the disturbance of the sample column and affecting the integrity and representativeness of the sample. Furthermore, the extraction stage still requires considerable manpower to overcome friction and adsorption effects, limiting on-site efficiency. During the extraction process, a extraction device is needed, but it is difficult to remove the sampling tube by simply pressing the extraction device manually.

[0003] Chinese invention patent with authorization announcement number CN114755051B discloses a soil sampling device for horticultural planting. In use, we found that although it has the advantage of convenient operation under general soil conditions, its soil entry drive and pull-out drag reduction still rely on separate tools and manual operation, which limits its adaptability and labor-saving degree.

[0004] Furthermore, most existing devices on the market still suffer from the same problems during use, for example: During the extraction process, the sampling tube relies on a separate extraction tool, which lacks coordinated constraints on transmission, guidance and state switching within the same device, making it difficult to reduce the overall labor intensity. Furthermore, the lifting stage lacks a controllable interface that automatically clamps and releases as the stroke progresses, making it difficult to reduce the lifting load under low disturbance conditions. Insufficient guidance and anti-sway capabilities during use, especially in complex soil layers and confined spaces, can easily lead to damage to the morphology of the sample column and a decrease in representativeness.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0030] Example 1, please refer to Figure 1A geological soil sampling device includes a sampling tube 2 and a power box 1. The bottom of the power box 1 is provided with a fixedly connected adapter 3, which is detachably connected to the sampling tube 2. The power box 1 is provided with a striking mechanism for automatically inserting the sampling tube 2 into the soil. It also includes two auxiliary rods 4, which are vertically arranged on both sides of the power box 1. The bottom of the auxiliary rods 4 is provided with a support plate 8. The two ends of the power box 1 are provided with rotatably connected adapter plates 5, which are movable up and down on the auxiliary rods 4. A pull-out plate 6 that can move up and down and rotate is provided between the auxiliary rods 4. The pull-out plate 6 is provided with a through-hole 61 for the sampling tube 2 to pass through. When the pull-out plate 6 is rotated to an inclined position, the inner walls on both sides of the pull-out hole 61 respectively adhere to the surface of the corresponding sampling tube 2.

[0031] The addition of the auxiliary rod 4 and the support plate 8 allows the auxiliary rod 4 to be placed vertically on the ground for fixation. Combined with the adapter plate 5, the auxiliary rod 4 can automatically limit the movement trajectory of the power box 1. In the traditional sampling process, the power box 1 needs to be manually supported. However, in this application, the sampling tube 2 does not need to be manually supported when in use, realizing automatic sampling by the sampling tube 2, which is more convenient and labor-saving.

[0032] During sampling, the auxiliary rod 4 is fixed to the support plate 8, ensuring that the auxiliary rod 4 can provide stable flow to the power box 1. When sampling is completed, the lifting plate 6 is rotated to press and fix the lifting plate 6 and the sampling tube 2. Then, the sampling tube 2 can be automatically removed by the up and down movement of the lifting plate 6. When the lifting plate 6 is tilted, the lifting hole 61 is in contact with the surface of the sampling tube 2, which can fully increase the friction between the lifting hole 61 and the sampling tube 2, so that the lifting plate 6 can better remove the sampling tube 2.

[0033] Please see Figure 9 and Figure 10In this embodiment, each of the support plates 8 is provided with a fixedly connected limiting plate 81. The inner sidewall of the limiting plate 81 is provided with a limiting groove 84. The sidewall of the limiting groove 84 is provided with symmetrically distributed limiting slide grooves. The limiting groove 84 is provided with a slidably connected limiting block 64. The two ends of the limiting block 64 are provided with limiting sliders 63 that are slidably connected to the limiting slide grooves. The two ends of the lifting plate 6 are provided with a fixedly connected rotating shaft 62. The rotating shaft 62 is rotatably connected to the limiting block 64. The limiting block 64 is provided with a torsion spring for driving the rotating shaft 62 to automatically rotate by a set angle. The bottom of the limiting groove 84 is provided with a vertically movable striking block 83. The striking block 83 is provided with a flexible connecting piece 65. The extension end of the connecting piece 65 is fixedly connected to the corresponding rotating shaft 62. When the limiting slider 63 is located at the bottom of the limiting slide groove, the downward movement of the striking block 83 can drive the rotating shaft 62 to rotate, so that the lifting plate 6 automatically rotates to a horizontal position.

[0034] The combination of the limiting block 64 and the limiting groove 84 ensures that the lifting plate 6 can only move vertically up and down, effectively guiding and limiting the flow. The torsion spring allows the lifting plate 6 to automatically rotate from a horizontal position to an inclined position without external force, thus enabling the lifting hole 61 to automatically tilt and fit against the sampling tube 2 for connection and fixation. The up and down movement of the striking block 83, by striking the limiting block 64, causes the lifting plate 6 to move upward, thereby pulling the sampling tube 2 upward. The addition of the connecting piece 65 ensures that when the limiting block 64 moves to its highest position, because the lifting hole 61 is fitted against the sampling tube 2, the striking block 83 moves downward, and the limiting block 64 loses its support. The gravity of the limiting block 64 and the lifting plate 6 cannot move downward automatically. The connecting piece 65, through a winding method, allows the striking block 83 to move downward. When the connecting piece 65 can no longer be stretched after moving a certain distance, as the striking block 83 continues to move downward, the connecting piece 65 can pull the rotating shaft 62 to rotate automatically, so that the pulling plate 6 can rotate from an inclined position to a horizontal position. In this way, the pulling hole 61 and the sampling tube 2 are no longer in contact. Under the action of gravity, the limiting block 64 can automatically move downward to the set position. In this way, the pulling plate 6 can be moved up and down by the repeated up and down movement of the striking block 83. At the same time, when the striking block 83 moves upward, the pulling plate 6 is in an inclined position and in contact with the sampling tube 2, so that the striking block 83 drives the sampling tube 2 to move upward by impact. When the striking block 83 moves downward, the pulling plate 6 can automatically rotate to a horizontal position, so that the pulling plate 6 can be disconnected from the sampling tube 2 and automatically move downward to the initial position, realizing the slow removal of the sampling tube 2.

[0035] Please see Figure 9 , Figure 10 and Figure 11In this embodiment, the bottom of the auxiliary rod 4 is provided with a fixedly connected rotating plate 45, the bottom of the rotating plate 45 is provided with a rotating groove 46, the outer side of the striking block 83 is provided with an adjusting shaft 82 that is slidably connected in the rotating groove 46, the support plate 8 is provided with a fixedly connected arc plate 7, the rotating plate 45 is provided with a through adjusting hole 47, the middle of the arc plate 7 is provided with a threaded bolt 71, the bolt 71 passes through the adjusting hole 47 and is threadedly connected to the limiting plate 81, and the arc plate 7 is provided with a locking rod 72 for engaging and fixing the adjusting hole 47.

[0036] The design of the adjusting hole 47, the arc plate 7, and the bolt 71 allows the auxiliary rod 4 to be fixed in a vertical position by the bolt 71. Combined with the rotation groove 46, the locking rod 72, and the adjusting shaft 82, the locking rod 72 engages with the adjusting hole 47, allowing the auxiliary rod 4 to tilt and rotate around the locking rod 72. This, combined with the gravity of the power box 1 and the rotational speed of the auxiliary rod 4, drives the striking block 83 upwards. The presence of the rotation groove 46 allows the adjusting shaft 82 to move within it, enabling the striking block 83 to move vertically upwards. This design also fully utilizes the kinetic energy of the rotating power box 1. The rotation of the power box 1 around the locking rod 72 drives the striking block 83 to move upward. At the moment of collision with the limiting block 64, the striking block 83 can convert the rotational kinetic energy into energy that drives the limiting block 64 to move upward, allowing the sampling tube 2 to be removed more easily. As is common knowledge, the process of removing the sampling tube 2 is the most strenuous when the sampling tube 2 is just being pulled outward. However, in this application, this rotation method, combined with the kinetic energy generated by the power box 1 during rotation, can generate a huge amount of energy in an instant, so that the sampling tube 2 can better overcome the friction in the initial process and become loose, making the sampling tube 2 easier to remove in the subsequent process. When the power box 1 is rotating, an initial rotational speed can also be manually provided to the power box 1 to increase the kinetic energy during the rotation process.

[0037] Please see Figure 9 , Figure 10 and Figure 11In this embodiment, the inner wall of the arc plate 7 is provided with an arc groove 73, and an arc slider is slidably connected within the arc groove 73. The arc slider is fixedly connected to the rotating plate 45, and the adjustment hole 47 passes through the arc slider. The design of the arc groove 73 and the arc slider allows the auxiliary rod 4 to rotate along the direction of the arc groove 73 when it rotates and tilts, making the rotation process more stable. The arc plate 7 is provided with a through slot, which passes through the arc groove 73, and the locking rod 72 passes through the slot and connects to the adjustment hole 47.

[0038] Please see Figure 3 , Figure 4 and Figure 5 , Figure 8 In this embodiment, the auxiliary rod 4 is provided with an internal thread groove 44, the adapter plate 5 is provided with a through-hole 50 for the auxiliary rod 4 to pass through, the inner wall of the adapter hole 50 is provided with an adjusting ring groove 521, the adjusting ring groove 521 is provided with a rotatable adjusting ring plate 56, the adjusting ring plate 56 is provided with a first arc plate 551 and a second arc plate 552 symmetrically distributed inside the adjusting ring plate 56, and the adjusting ring plate 56 is provided with a plurality of first telescopic tubes 561 that drive the first arc plate 551 and the second arc plate 552 to move back and forth respectively. The first arc plate 551 and the second arc plate 552 are connected to form a tube, and the inner walls of the first arc plate 551 and the second arc plate 552 are provided with external threads 55 that match the internal thread groove 44.

[0039] The design of the internal thread groove 44, in conjunction with the adjusting ring plate 56, the first arc plate 551, the second arc plate 552, and the external thread 55, allows the first arc plate 551 and the second arc plate 552 to separate and retract into the adapter hole 50 during the sampling process of the sampling tube 2. This disconnects the external thread 55 from the internal thread groove 44, allowing the adapter plate 5 to slide up and down on the auxiliary rod 4 without affecting the vibration of the power box 1 during the insertion and sampling of the sampling tube 2. When the sampling tube 2 is fully inserted, the adapter plate 5 is located at the bottom of the auxiliary rod 4. The first arc plate 551 and the second arc plate 552 are then connected to form a tube, and the external thread 55 matches the internal thread groove 44. By adjusting the rotation of the adjusting ring plate 56, the power box 1 can be automatically raised without manual intervention, making it more convenient and labor-saving.

[0040] Please see Figure 5 and Figure 8In this embodiment, the adapter plate 5 is provided with a driving mechanism for controlling the extension and retraction of the first telescopic tube 561. The driving mechanism includes a pressing telescopic mechanism 501, a driving plate 504, and a second telescopic tube 529. The upper end of the adapter ring plate 52 is provided with a first annular groove 528, and the bottom of the first annular groove 528 is provided with a second telescopic tube 529 that is fixedly connected and communicates with it. The bottom of the second telescopic tube 529 is fixedly connected to the adjusting ring plate 56. The adjusting ring plate 56 is provided with a communicating groove for connecting the first telescopic tube 561 and the second telescopic tube 529. The adapter ring plate 52 and the adjusting ring plate 56 are connected to each other. The grooves 521 are rotatably and sealingly connected. The inner wall of the adjusting ring groove 521 is provided with a second ring groove 505 that communicates with the first ring groove 528. A driving groove 506 is provided on one side of the second ring groove 505. A driving plate 504 is slidably and sealingly connected in the driving groove 506. A pressing telescopic mechanism 501 is also fixedly connected in the driving groove 506. The telescopic end of the pressing telescopic mechanism 501 is provided with a driving rod 503 fixedly connected to the driving plate 504. A pressing rod 502 is provided on the outside of the adapter plate 5. The pressing rod 502 is fixedly connected to the pressing end of the pressing telescopic mechanism 501. The pressing telescopic mechanism 501 adopts the pressing mechanism in the field of existing pressing ballpoint pens. After one end of the pressing mechanism is pressed, the other end automatically extends. After pressing again, the extended end automatically retracts. This mechanism is prior art, so this application will not describe its specific structure.

[0041] By rotating and sealing the adapter ring plate 52 and adjusting ring groove 521, and cooperating with the connection between the second telescopic tube 529 and the first telescopic tube 561, the reciprocating motion of the drive plate 504 and the hydraulic transmission can realize the telescopic control of the first telescopic tube 561. The addition of the pressing telescopic mechanism 501 allows manual pressing of the pressing rod 502, which in turn controls the reciprocating motion of the drive plate 504.

[0042] Please see Figure 1 , Figure 2 and Figure 11 In this embodiment, the auxiliary rod 4 located below the internal thread groove 44 is provided with a fixed platform 43 for fixing and placing the adapter plate 5. The auxiliary rod 4 located above the fixed platform 43 is provided with a mating ring groove 42 that communicates with the internal thread groove 44. After the first arc plate 551 and the second arc plate 552 are mated, the external thread 55 is located in the mating ring groove 42. The fixed platform 43 is located above the rotating plate 45.

[0043] The design of the fixed platform 43 can effectively support the adapter plate 5 when it moves to the bottom. The design of the mating ring groove 42 allows the external thread 55 to be connected to the internal thread groove 44 before they are connected. The first arc plate 551 and the second arc plate 552 are connected in the mating ring groove 42 to form a tubular shape. In this way, the external thread 55 is located in the mating ring groove 42, which allows the external thread 55 to be better matched and connected by rotation, effectively preventing the problem of the external thread 55 and the internal thread groove 44 not being able to mate.

[0044] Please see Figure 5 , Figure 7 In this embodiment, the adjusting ring groove 521 is provided with a rotatably connected transition ring plate 52, the transition ring plate 52 is slidably connected to the adjusting ring plate 56, the outer wall of the transition ring plate 52 is provided with a plurality of guide grooves, the inner wall of the adjusting ring plate 56 is provided with a guide plate 522 fixedly connected and slidably connected to the guide grooves, and the transition ring plate 52 is provided with a support ring plate 54 that can drive the adjusting ring plate 56 to move up and down.

[0045] The design of the guide groove and the guide plate 522 enables the synchronous rotation of the adjusting ring plate 56 and the transition ring plate 52. At the same time, the adjusting ring plate 56 can achieve synchronous up and down movement by supporting the up and down movement of the supporting ring plate 54 during the rotation. In this way, the connection between the internal thread groove 44 and the external thread 55 can be made faster by supporting the upward movement of the supporting ring plate 54 and cooperating with the rotation within the mating ring groove 42.

[0046] Please see Figure 4 , Figure 5 and Figure 6 , Figure 7 In this embodiment, the adapter ring plate 52 is provided with multiple ejector springs 542 for automatically driving the adjusting ring plate 56 upward. The outer wall of the adapter ring plate 52 is provided with multiple through-type extrusion grooves, each containing an extrusion plate 541. The extrusion plate 541 is fixedly connected to the support ring plate 54. A synchronization ring plate 511 is sleeved on the outer wall of the adapter ring plate 52, and the synchronization ring plate 511 is placed on the extrusion plate 541. The adapter plate 52 is provided with multiple synchronization rods 51, the bottom of which movably passes through the adjusting ring groove 521 and... The synchronous ring plate 511 is connected. The outer side of the support ring plate 54 is provided with a locking groove 543. The inner wall of the adapter ring plate 52 is provided with a positioning groove 525. The positioning groove 525 is provided with a locking tongue 527 that is slidably connected and used to engage with the locking groove 543. The positioning groove 525 is also provided with a first spring 526 for automatically ejecting the locking tongue 527. The positioning groove 525 is also provided with a flexible tensioning member 524 that is connected to the locking tongue 527. The adapter plate 5 is provided with a pressing rod 523 below it. The pressing rod 523 moves through the locking groove 543 and is connected to the tensioning member 524.

[0047] The addition of the ejector spring 542 enables the support ring plate 54 to drive the adjusting ring plate 56 to move automatically upward. The design of the pressing plate 541, the synchronous ring plate 511, and the synchronous rod 51 allows the support ring plate 54 to automatically return to its initial position by pressing the synchronous rod 51 after the adapter plate 5 moves to its uppermost position. Combined with the engagement of the locking tongue 527 and the locking groove 543, the support ring plate 54 is automatically fixed after being pressed. When the support ring plate 54 moves to its lowermost position, and the adapter plate 5 moves back to the fixed platform 43, the adjusting ring plate 56 can automatically fall above the support ring plate 54, thus enabling the first... The first arc plate 551 and the second arc plate 552 move into the mating ring groove 42, thereby facilitating the connection between the external thread 55 and the internal thread groove 44. The design of the extrusion rod 523, the first spring 526 and the tensioning member 524 allows the extrusion rod 523 to be extruded by the fixed platform 43 when the adapter plate 5 moves to the fixed platform 43. This causes the locking tongue 527 to automatically retract through the tensioning member 524, thus the support ring plate 54 loses its fixation. Under the action of the ejector spring 542, the adjusting ring plate 56 can be automatically lifted upward. With the rotation of the adjusting ring plate 56, the external thread 55 and the internal thread groove 44 can be better matched and connected.

[0048] Please see Figure 2 In this embodiment, a connecting shaft 13 is provided between the power box 1 and the adapter plate 5 for rotatable connection, and a vibration motor 10 is provided inside the power box 1 for fixed connection and for striking the sampling tube 2.

[0049] Please see Figure 2 , Figure 4 In this embodiment, a first bevel gear 53 is fixedly connected to the outer side of the adapter ring plate 52, and a second bevel gear 121 that meshes with the first bevel gear 53 is provided in the adjusting ring groove 521. The output end of the vibration motor 10 is provided with a drive shaft 12, and a unidirectional rotating striking wheel 11 is provided on the drive shaft 12. The extended end of the drive shaft 12 moves through the connecting shaft 13 and is unidirectionally rotating connected to the second bevel gear 121.

[0050] The design of the first bevel gear 53 and the second bevel gear 121 enables the rotation control of the adapter ring plate 52. Combined with the one-way rotation connection of the drive shaft 12, when the striking wheel 11 needs to be struck and vibrated, the rotation of the drive shaft 12 can drive the striking wheel 11 to rotate. The one-way rotation connection design ensures that the drive shaft 12 will not drive the second bevel gear 121 to rotate. When it is necessary to drive the second bevel gear 121 to rotate, it is only necessary to control the drive shaft 12 to rotate in the opposite direction to achieve the rotation of the second bevel gear 121, while the striking wheel 11 does not rotate.

[0051] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the upper end of the auxiliary rod 4 is provided with a cover plate 41 that is detachably connected and used for pressing the synchronizing rod 51. The addition of the cover plate 41 enables the adapter plate 5 to move upward to a set position, and the pressing of the cover plate 41 on the synchronizing rod 51 realizes the automatic downward movement of the support ring plate 54 to restore its initial position.

[0052] When this application is used: Step 1: First, place the puller plate 6 in the set position so that the puller hole 61 is at the same position as the sampling point. At this time, the external thread 55 and the internal thread groove 44 are connected. Just control the vibration motor 10 to rotate, and the first bevel gear 53 will be driven to rotate through the drive shaft 12. Through the gear transmission, the second bevel gear 121 will be driven to rotate, so that the adapter ring plate 52 can rotate. The rotation of the adapter ring plate 52 can drive the power box 1 to move automatically upward to the set position under the thread drive. At this time, the cover plate 41 will press the synchronizing rod 51, so that the support ring plate 54 can move automatically to the bottom and be automatically fixed by the locking tongue 527 engaging with the locking groove 543. Step 2: Then connect and fix the sampling tube 2 to the adapter 3. At this time, manually press the pressing rod 502. By pressing the telescopic mechanism 501, control the drive plate 504 to move. Then, using the principle of hydraulic transmission, control the first telescopic tube 561 to retract, so that the first arc plate 551 and the second arc plate 552 are automatically retracted. The external thread 55 separates from the internal thread groove 44. The adapter plate 5 loses the thread fixation. Due to gravity, it will automatically move downward. The sampling tube 2 can be automatically inserted into the soil through the pulling hole 61 by the vibration of the power box 1. Step 3: Next, start the vibration motor 10 to rotate in the opposite direction, which will drive the striking wheel 11 to vibrate and strike the sampling tube 2, so that the sampling tube 2 can be slowly inserted into the soil for sampling. When the adapter plate 5 moves to the fixed platform 43, the sampling is completed. At the same time, the first arc plate 551 and the second arc plate 552 are located in the docking ring groove 42, and the manual press rod 502 is squeezed again. Using the characteristics of the press telescopic mechanism 501, the drive plate 504 is restored to the initial position. The first telescopic tube 561 controls the first arc plate 551 and the second arc plate 552 to be connected and fixed into a tube shape. When the pressing rod 523 contacts and presses the fixed platform 43, it can squeeze the tensioning member 524, so that the locking tongue 527 can be automatically retracted. At this time, the support ring plate 54 can move upward automatically under the action of the ejection spring 542, so that the external threads 55 in the first arc plate 551 and the second arc plate 552 can always maintain an upward moving and fitting state. Step 4: Then disconnect the adapter 3 from the sampling tube 2, and then control the vibration motor 10 to rotate in the forward direction and control the adapter ring plate 52 to rotate. As it rotates, it can drive the external thread 55 to better match and connect with the internal thread groove 44. Under the action of the thread, it can automatically move the power box 1 upward without manual lifting, which is more labor-saving. When the adapter plate 5 moves to the cover plate 41, the cover plate 41 squeezes the synchronous rod 51, which can make the support ring plate 54 move downward automatically and be locked by the locking tongue 527. Step 5: When it is necessary to remove the sampling tube 2, simply remove the bolt 71, and then rotate the auxiliary rod 4 around the adjusting shaft 82. When the adjusting hole 47 on the rotating plate 45 rotates to the slot, insert the locking rod 72 into the slot. At this time, rotate the auxiliary rod 4 downwards around the locking rod 72 at a certain speed. The rotation of the auxiliary rod 4 can drive the striking block 83 at the other end to rotate upwards. As the striking block 83 moves upwards, the connecting piece 65 loosens. At this time, the torsion spring can quickly drive the lifting plate 6 to rotate to an inclined position, so that the inner wall of the lifting hole 61 fits against the sampling tube 2. In this way, when the striking block 83 contacts and strikes the limiting block 64, the lifting plate 6 and the sampling tube 2 are automatically connected and fixed. Thus, during the rotation of the auxiliary rod 4, the kinetic energy of the power box 1 is converted into the striking kinetic energy of the striking block 83 striking the limiting block 64. The energy generated at the moment of contact enables the sampling tube 2 to... It is easier to overcome the friction between the sample tube and the soil, causing the sample tube 2 to loosen. After the tapping is completed, the auxiliary rod 4 is manually rotated upwards, causing the tapping block 83 to move downwards automatically. After the tapping block 83 moves downwards, the limiting block 64 loses its support. At this time, the weight of the limiting block 64 and the lifting plate 6 cannot move downwards automatically. When the tapping block 83 moves downwards a certain distance, the connecting piece 65 cannot be stretched. As the tapping block 83 continues to move downwards, the connecting piece 65 can pull the rotating shaft 62 to rotate automatically, so that the lifting plate 6 can rotate from an inclined position to a horizontal position. In this way, the lifting hole 61 and the sample tube 2 are no longer in contact. Under the action of gravity, the limiting block 64 can move downwards automatically to the set position, so that the lifting plate 6 can move downwards automatically along the sample tube 2. In this way, it is only necessary to manually rotate the auxiliary rod 4 back and forth to easily remove the sample tube 2 through the lever principle.
