Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and more specifically, to a soil sampling device and method for steep slopes used in geological exploration. Background Technology

[0002] In geological exploration, soil sampling is a crucial step in obtaining information about the physical and mechanical properties, chemical composition, and structural characteristics of underground soil. This requires the use of soil sampling devices to collect samples, which are then analyzed to determine their composition. Manual sampling using tools is labor-intensive and inefficient; therefore, vehicle-mounted sampling devices are now commonly used. These devices are moved to a designated location, and the sampling tube is rotated while being pressed downwards into the soil to complete the sampling process.

[0003] When drilling and sampling are required under steep slope geological conditions, conventional vehicle-mounted sampling devices are unstable on the slope and have poor stability, making them inconvenient to push and use. Furthermore, after sampling, the process of removing the sample from the sampling tube is also quite cumbersome due to the adhesion between the sample and the sampling tube. Summary of the Invention

[0004] The purpose of this invention is to provide a soil sampling device and method for steep slopes for geological exploration, which can conveniently push the vehicle to a designated position on the slope and fix it, and can discharge the sample from the sampling tube after sampling is completed.

[0005] This invention is achieved through the following technical solution: a soil sampling device for steep slopes used in geological exploration, comprising:

[0006] The vehicle body has rollers at its bottom and positioning components at both the front and rear ends for abutting against the slope of a steep slope and keeping the rollers suspended in the air.

[0007] A movable frame, comprising a base and a mounting bracket vertically disposed on the base, wherein the base is slidably disposed on the vehicle body along the length direction of the vehicle body and is capable of rotating relative to the vehicle body;

[0008] A sampling mechanism, comprising a sampling seat and a sampling component slidably disposed on the sampling seat, wherein one end of the sampling seat is rotatably disposed at the end of the mounting frame away from the base, and the other end of the sampling seat is perpendicularly facing the ground, and the base is provided with a fixing member for fixing the position of the sampling seat;

[0009] A striking element, comprising support rods disposed on both sides of the mounting frame and a striking roller connected between the two support rods;

[0010] The driving mechanism includes a driving rope and a driving electric cylinder. One end of the driving rope is connected to the mounting frame and the other end is connected to the sampling seat. The driving electric cylinder is connected to the mounting frame through a cylinder seat. A lifting block is provided on the piston rod of the driving electric cylinder. The lifting block is used to lift the middle section of the driving rope upward so that the sampling seat swings towards the mounting frame. The mounting frame is provided with a first release frame for disengaging the driving rope from the lifting block.

[0011] Furthermore, the lifting block includes a sloping baffle, an arc-shaped concave surface, and an arc-shaped convex surface in sequence from the side near the sampling seat to the side away from the sampling seat; when the lifting block contacts the drive rope, the arc-shaped concave surface is located directly below the drive rope; the first release frame extends obliquely upward from the side near the sampling seat to the side away from the sampling seat, and a notch for the lifting block to pass through is provided in the middle of the first release frame.

[0012] Furthermore, the sampling seat is provided with a first mounting block, the first mounting block is provided with a mounting shaft, the mounting shaft is provided with an annular groove, one end of the drive rope is provided with a connecting ring, the connecting ring is sleeved in the annular groove; the mounting frame is provided with a second mounting block, the other end of the drive rope is provided with a connecting bolt, and both the second mounting block and the base are provided with threaded holes for the connecting bolt to be inserted.

[0013] Furthermore, a rotating shaft is provided in the middle of the electric cylinder base and is rotatably connected to the mounting bracket through the rotating shaft. An anti-rotation bolt is provided at the end of the electric cylinder base away from the drive electric cylinder, and two threaded holes for inserting the anti-rotation bolt are provided on the mounting bracket.

[0014] Furthermore, the base is also provided with a second release frame that has the same shape as the first release frame. When the anti-rotation bolt is inserted into one of the threaded holes, the drive electric cylinder can drive the lifting block into the notch of the first release frame. When the anti-rotation bolt is inserted into the other threaded hole, the drive electric cylinder can drive the lifting block into the notch of the second release frame.

[0015] Furthermore, both sides of the vehicle body are provided with strip-shaped grooves along their own length direction, and the bottom of one end of the strip-shaped groove is connected to a groove. Both sides of the base are provided with sliding rollers, which slide along the length direction of the strip-shaped groove and can descend into the groove. The end of the base away from the sliding roller is provided with an abutment seat, and the abutment seat is provided with a positioning bolt. The vehicle body is provided with threaded holes for the positioning bolts to be inserted. When the sliding roller slides into the groove and the mounting bracket rotates to be perpendicular to the vehicle body, the positioning bolts can be inserted into the threaded holes.

[0016] Furthermore, the vehicle body is provided with a positioning rod, and the positioning rod has a threaded hole for the positioning bolt to be inserted. When the mounting bracket rotates to abut against the vehicle body and the sliding roller slides to the end of the strip groove away from the groove, the positioning bolt can be inserted into the threaded hole of the positioning rod.

[0017] Furthermore, both sides of the mounting bracket are provided with sliding grooves along their width direction, the support rod is slidably disposed in the sliding grooves, the support rod is provided with an oblong hole, the oblong hole is provided with a fastening bolt, and the mounting bracket is provided with a threaded hole for the fastening bolt to be inserted.

[0018] Furthermore, the fixing component includes a fixing seat, on which a fixing bolt is provided, and an arc-shaped slide bar is provided at one end of the sampling seat near the base, and the fixing bolt can abut against the arc-shaped slide bar to limit the position of the sampling seat.

[0019] The present invention also provides a sampling method using the above-mentioned geological exploration steep slope soil sampling device, comprising the following steps:

[0020] S1. Push the vehicle body to the designated position along the slope of the steep slope. During the pushing process, slide the base towards the rear of the vehicle body and keep the mounting bracket in contact with the vehicle body.

[0021] S2. After pushing the vehicle body to the designated sampling position on the slope, use the positioning component to suspend the wheels in the air to position the vehicle body; then slide the base towards the front of the vehicle body and rotate the mounting bracket to a position perpendicular to the vehicle body;

[0022] S3. Keep the sampling seat vertical under its own weight. After the sampling seat is stable, fix the sampling seat with the fastener.

[0023] S4. Drive the sampling component along the length of the sampling seat, so that the sampling component can sample the soil on the slope in the vertical direction.

[0024] S5. After sampling is completed, the fixing of the fixing component on the sampling seat is released. Then, the driving mechanism drives the sampling seat to swing towards the mounting frame and then swing back to the initial position. During this process, the sampling component can collide with the striking component, so that the soil sample taken out is separated from the sampling component.

[0025] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0026] 1. This invention involves creating strip-shaped grooves on both sides of the vehicle body and a recess at the bottom of one end of the strip-shaped grooves. By installing sliding rollers on both sides of the base, the rollers slide along the length of the strip-shaped grooves and descend into the recesses. During the process of pushing the base along the length of the vehicle body, the strip-shaped grooves restrict the movement of the base. Once the sliding rollers reach the end of the strip-shaped grooves and descend into the recesses, they cannot move back or forth, thus restricting the base to rotate without sliding. This allows the operator to rotate the mounting bracket to a position perpendicular to the vehicle body. Furthermore, during the process of pushing the vehicle body, the base slides towards the rear of the vehicle body, keeping the mounting bracket in contact with the vehicle body, lowering the center of gravity of the overall structure for easier pushing. After pushing the vehicle body to the designated sampling position on the slope, the base slides towards the front of the vehicle body, and the mounting bracket is rotated to a position perpendicular to the vehicle body to facilitate the sampling process.

[0027] 2. The present invention drives the sampling seat to move through the driving mechanism, thereby causing the sampling component to swing periodically. When the sampling cylinder moves back to the initial position, it can collide with the striking part. Under the dual action of centrifugal force and vibration generated by the impact, the sample can be smoothly moved out of the sampling cylinder. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] Example

[0039] The following is for reference Figures 1-7 As shown in the illustration, and further illustrated with specific embodiments, this embodiment provides a soil sampling device for steep slopes used in geological exploration. (Refer to...) Figure 1 , Figure 2 As shown, the device includes a vehicle body 1, a moving frame 2, a sampling mechanism 3, a striking component 4, and a drive mechanism 5. Rollers 11 are installed at all four corners of the bottom of the vehicle body 1, and each roller 11 is equipped with anti-slip tires to ensure stability when pushing on slopes. Positioning components 12 are installed at both the front and rear ends of the vehicle body 1, as shown in the diagram. Figure 3As shown, the positioning component 12 includes a mounting plate 121 and a positioning electric cylinder 122 mounted on the mounting plate 121. The piston rod of the positioning electric cylinder 122 is equipped with a positioning disc 123. When the positioning electric cylinder 122 is activated, it drives the positioning disc 123 to press against the slope of the steep slope and makes the roller 11 suspended in the air, thus stabilizing the vehicle body 1. The moving frame 2 includes a base 21 and a mounting frame 22 vertically mounted on the base 21. The base 21 slides along the length of the vehicle body 1 and can rotate relative to the vehicle body 1. During the process of pushing the vehicle body 1, the base 21 slides towards the rear of the vehicle body 1 and the mounting frame 22 is kept in contact with the vehicle body 1, lowering the center of gravity of the overall structure to facilitate pushing by the staff and prevent the vehicle body 1 from tipping over during the pushing process on the steep slope. After pushing the vehicle body 1 to the designated sampling position on the slope, the base 21 slides towards the front of the vehicle body 1 and the mounting frame 22 is rotated to a position perpendicular to the vehicle body 1 to facilitate the sampling process.

[0040] Reference Figure 2 , Figure 3 As shown, both sides of the vehicle body 1 are provided with strip grooves 13 along their own length direction. The bottom of one end of the strip groove 13 is connected to a groove 14. Both sides of the base 21 are provided with sliding rollers 211. The sliding rollers 211 are slidably disposed in the strip groove 13 along its length direction and can descend into the groove 14. When the base 21 is pushed along the length direction of the vehicle body 1, the sliding rollers 211 slide along the length direction of the strip groove 13, which limits the movement direction of the base 21. When the sliding rollers 211 are pushed to the end of the strip groove 13 and descend into the groove 14, the sliding rollers 211 cannot move back and forth. Therefore, the base 21 can be limited so that it can only rotate and will not slide during the rotation. This makes it convenient for the staff to rotate the mounting bracket 22 to a state perpendicular to the vehicle body 1. A contact seat 212 is provided at the end of the base 21 away from the sliding roller 211. A positioning bolt 213 is provided on the contact seat 212. A threaded hole for the positioning bolt 213 is provided on the vehicle body 1. When the sliding roller 211 slides into the groove 14 and the mounting bracket 22 rotates to be perpendicular to the vehicle body 1, the positioning bolt 213 can be inserted into the threaded hole to fix the relative position of the mounting bracket 22 and the vehicle body 1. A positioning rod 15 is also provided on the vehicle body 1. A threaded hole for the positioning bolt 213 is provided on the positioning rod 15. When the mounting bracket 22 rotates to abut against the vehicle body 1 and the sliding roller 211 slides to the end of the strip groove 13 away from the groove 14, the positioning bolt 213 can be inserted into the threaded hole of the positioning rod 15 to ensure that the moving frame 2 will not shake during the process of pushing the vehicle body 1 as a whole.

[0041] Reference Figure 4As shown, the sampling mechanism 3 includes a sampling seat 31 and a sampling component 32 that is slidably disposed on the sampling seat 31. The structure of the sampling mechanism 3 is the same as that used in the prior art. The sampling seat 31 is equipped with a motor screw mechanism (not shown in the figure) for driving the sampling component 32 to slide along the length direction of the sampling seat 31. The sampling component 32 includes a sampling motor 321 and a sampling cylinder 322. The sampling motor 321 drives the sampling cylinder 322 to rotate, and then the motor screw mechanism drives the sampling component 32 to move downward as a whole, so that the sampling cylinder 322 can move downward and perform soil sampling. One end of the sampling seat 31 is rotatably mounted on the end of the mounting frame 22 away from the base 21, and the other end of the sampling seat 31 faces vertically to the ground. The base 21 is provided with a fixing member 23 for fixing the position of the sampling seat 31. The fixing member 23 includes a fixing seat 231 with a fixing bolt 232. An arc-shaped slide bar 313 is provided at the end of the sampling seat 31 near the base 21. The fixing bolt 232 abuts against the arc-shaped slide bar 313 to define the position of the sampling seat 31. After the positions of the vehicle body 1 and the moving frame 2 are fixed, the sampling seat 31 will be in a vertical state under its own weight. Then, the fixing bolt 232 is used to press against the designated position of the arc-shaped slide bar 313, thus fixing the position of the bottom of the sampling seat 31 to prevent the sampling cylinder 322 from rotating during the sampling process and affecting the sampling process.

[0042] Reference Figure 4 As shown, the striking component 4 includes support rods 41 disposed on both sides of the mounting frame 22 and a striking roller 42 connected between the two support rods 41. After sampling, the fixing effect of the fixing component 23 on the sampling seat 31 is released. Under the action of external force, the sampling seat 31 can drive the sampling component 32 to swing. During the swing, when the sampling cylinder 322 moves back to the initial position, it can collide with the striking roller 42. Under the dual action of centrifugal force and vibration generated by the impact, the sample can be smoothly moved out of the sampling cylinder 322. Both sides of the mounting frame 22 are provided with sliding grooves along their own width direction. The support rods 41 are slidably disposed in the sliding grooves. The support rods 41 are provided with waist-shaped holes 411. Fastening bolts 412 are disposed in the waist-shaped holes 411. The mounting frame 22 is provided with threaded holes for the fastening bolts 412 to be inserted. By moving the support rod 41 along the length of the chute and tightening the fastening bolt 412 at different positions of the waist-shaped hole 411, the position of the striking roller 42 can be adjusted to adapt to the position of the sampling cylinder 322 when it is in its natural state under the action of gravity when working on steep slopes of different gradients.

[0043] Reference Figure 4 , Figure 5As shown, the drive mechanism 5 includes a drive rope 51 and a drive cylinder 52. One end of the drive rope 51 is connected to the mounting frame 22 and the other end is connected to the sampling seat 31. The drive cylinder 52 is connected to the mounting frame 22 through a cylinder seat 53. A lifting block 54 is provided on the piston rod of the drive cylinder 52. The lifting block 54 is used to lift the middle section of the drive rope 51 upward so that the sampling seat 31 swings towards the mounting frame 22. A first release frame 55 is provided on the mounting frame 22 to disengage the drive rope 51 from the lifting block 54. The drive cylinder 52 is activated, and its piston rod drives the lifting block 54 upward. When the lifting block 54 rises to contact the drive rope 51, it can lift the middle section of the drive rope 51 upward. Since the position of the mounting frame 22 is fixed, the position of the end of the drive rope 51 connected to the mounting frame 22 will not change, while the end of the drive rope 51 connected to the sampling seat 31 will drive the sampling seat 31 to move closer to the mounting frame 22. After the drive cylinder 52 drives the lifting block 54 to the designated position, the drive rope 51 will disengage from the lifting block 54 under the action of the first release frame 55. Under its own weight, the sampling seat 31 will drive the sampling component 32 to swing to the initial state (i.e., the vertical state). At this time, the sampling cylinder 322 will collide with the striking roller 42. During the process of the sampling seat 31 being periodically swung by the drive mechanism 5, the sample can fall out of the sampling cylinder 322.

[0044] Reference Figure 6 As shown, the lifting block 54 includes a sloping stop 541, an arc-shaped concave surface 542, and an arc-shaped convex surface 543 sequentially from the side near the sampling seat 31 to the side away from the sampling seat 31; when the lifting block 54 contacts the drive rope 51, the arc-shaped concave surface 542 is located directly below the drive rope 51; the first release frame 55 extends obliquely upward from the side near the sampling seat 31 to the side away from the sampling seat 31, and a notch is provided in the middle of the first release frame 55 for the lifting block 54 to pass through. When the lifting block 54 contacts the drive rope 51, the arc-shaped concave surface 542 supports the drive rope 51 directly below it and drives the middle section of the drive rope 51 upward. The drive rope 51 then swings the sampling seat 31 towards the mounting frame 22. When the drive rope 51 reaches the position of the first release frame 55, under the action of the first release frame 55, the drive rope 51 moves from the arc-shaped concave surface 542 to the arc-shaped convex surface 543 on the lifting block 54. After the drive rope 51 reaches the arc-shaped convex surface 543, as the lifting block 54 continues to move, the drive rope 51 disengages from the lifting block 54, thus no longer applying tension to the sampling seat 31. Under the action of gravity, the sampling seat 31 drives the sampling assembly 32 to swing back to its initial position. It should be noted that the bottom of the lifting block 54 has an arc-shaped bottom surface 544 to ensure that the subsequent drive cylinder 52 can drive...

[0045] Reference Figure 5 , Figure 7As shown, the sampling base 31 is provided with a first mounting block 311, and the first mounting block 311 is provided with a mounting shaft 312. The mounting shaft 312 has an annular groove. One end of the drive rope 51 is provided with a connecting ring 511, which is fitted into the annular groove. The mounting frame 22 is provided with a second mounting block 221, and the other end of the drive rope 51 is provided with a connecting bolt 512. Both the second mounting block 221 and the base 21 have threaded holes for the connecting bolt 512 to be inserted. Because the bottom of the sampling cylinder 322 is relatively low, when the sampling base 31 is in a vertical position, the driving mechanism 5 can drive the sampling mechanism 3 to collide with the striking piece 4, causing a small portion of the sample to be moved out of the sampling cylinder 322. The remaining portion of the sample needs to be completely removed by continuing to strike the sampling cylinder 322 after the mounting frame 22 is rotated to abut against the vehicle body 1. By removing the connecting bolt 512 on the drive rope 51 from the threaded hole on the second mounting block 221 and inserting it into the threaded hole of the base 21, the state of the drive rope 51 can be changed. At this time, by lifting the middle part of the drive rope 51 upward, the drive rope 51 can drive the first mounting block 311 to move upward. The first mounting block 311 drives the sampling seat 31 to rise. After the drive rope 51 is released, the sampling seat 31 falls down under the action of gravity until it abuts against the first mounting block 311 and the mounting frame 22, which can cause the sampling cylinder 322 to vibrate so as to discharge the sample.

[0046] Reference Figure 4 , Figure 5As shown, a rotating shaft 531 is provided in the middle of the electric cylinder base 53 and is rotatably connected to the mounting bracket 22 through the rotating shaft 531. An anti-rotation bolt 532 is provided at the end of the electric cylinder base 53 away from the drive electric cylinder 52. Two threaded holes for inserting the anti-rotation bolt 532 are provided on the mounting bracket 22. A second release bracket 56 with the same shape as the first release bracket 55 is also provided on the base 21. The second release bracket 56 also has a notch. When the anti-rotation bolt 532 is inserted into one of the threaded holes, the drive electric cylinder 52 can drive the lifting block 54 into the notch of the first release bracket 55. When the anti-rotation bolt 532 is inserted into the other threaded hole, the drive electric cylinder 52 can drive the lifting block 54 into the notch of the second release bracket 56. After the mounting bracket 22 abuts against the vehicle body 1, the anti-rotation bolt 532 is removed from one of the threaded holes on the mounting bracket 22. The electric cylinder seat 53 is rotated to a specified angle and the anti-rotation bolt 532 is inserted into another threaded hole on the mounting bracket 22. The electric cylinder seat 53 can then drive the drive electric cylinder 52 to rotate to a specified angle. At this time, the drive electric cylinder 52 drives the lifting block 54 to move out of the cylinder. The arc-shaped concave surface 542 of the lifting block 54 can also drive the middle part of the drive rope 51 to move upward, so as to drive the sampling seat 31 to swing. When the drive rope 51 contacts the second release frame 56, it can move to the arc-shaped convex surface 543 of the lifting block 54 under the action of the second release frame 56, and finally disengage from the lifting block 54. The sampling seat 31 moves back to the initial position under the action of gravity and abuts against the mounting bracket 22. The sampling cylinder 322 is in a downward tilted state. When subjected to vibration, the sample can be discharged from the sampling cylinder 322.

[0047] This embodiment also provides a sampling method using the above-mentioned geological exploration steep slope soil sampling device, including the following steps:

[0048] S1. Push the vehicle body 1 to the designated position along the slope of the steep slope. During the pushing process, slide the base 21 toward the rear of the vehicle body 1 and keep the mounting bracket 22 in contact with the vehicle body 1.

[0049] S2. After pushing the vehicle body 1 to the designated sampling position on the slope, the wheels are suspended in the air by the positioning component 12 to position the vehicle body 1; then the base 21 is slid toward the head of the vehicle body 1 and the mounting bracket 22 is rotated to a position perpendicular to the vehicle body 1.

[0050] S3. Keep the sampling seat 31 vertical under its own weight. After the sampling seat 31 is stable, fix the sampling seat 31 with the fastener 23.

[0051] S4. Drive the sampling component 32 along the length of the sampling seat 31, so that the sampling component 32 can sample the soil on the slope in the vertical direction.

[0052] S5. After sampling is completed, the fixing effect of the fixing member 23 on the sampling seat 31 is released. Then, the driving mechanism 5 drives the sampling seat 31 to swing towards the mounting frame 22 and then swing back to the initial position. During this process, the sampling component 32 can collide with the striking member 4, so that the soil sample taken out is separated from the sampling component 32.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
