Description

Technical Field

[0001] The present invention relates to the technical field of soil layer sampling and detection equipment, in particular to a soil layer detection equipment for multiple terrains and a use method thereof. Background Art

[0002] Soil layer testing is an essential foundational task in fields such as geological exploration, environmental monitoring, agricultural soil research, and engineering construction. Accurately obtaining representative soil samples while preserving their original state, including information on structure, moisture, and layers, is crucial for subsequent laboratory analysis and directly impacts the reliability of test results.

[0003] Currently, common soil sampling equipment on the market mainly includes manual soil augers, hydraulic / mechanical soil samplers, and some semi-automatic sampling equipment. However, these devices have many significant limitations when dealing with complex and diverse actual working environments, and are unable to meet the modern testing needs of efficiency, accuracy, and convenience:

[0004] 1. Traditional equipment is often bulky and difficult to maintain stability on complex terrain, resulting in inaccurate sampling point positioning. The sampling operation itself becomes difficult and dangerous due to the shaking of the equipment.

[0005] 2. Most existing equipment can only perform sampling operations at vertical or near-vertical angles. However, in practical applications, such as slope surveys, research on special geological structures, and sampling near underground pipelines, it is often necessary to obtain soil samples at specific angles to obtain information in specific directions or layers. Existing equipment often relies on complex external supports, manual fixation, or large, specialized machinery to achieve this type of oblique sampling. This is extremely inconvenient, time-consuming, and labor-intensive, and accuracy is difficult to guarantee.

[0006] 3. After sampling, immediate on-site sealing of samples is a critical step in ensuring sample integrity and preventing contamination. However, most existing equipment lacks integrated, efficient, and automated sample sealing capabilities. Operators typically need to manually transfer samples from the sampler into separate containers and then seal them. This process is not only time-consuming and increases the risk of sample exposure to air contamination or structural disturbance, but is also inconvenient and error-prone in harsh field environments, making it difficult to ensure consistent and reliable sealing.

[0007] To this end, we propose a soil layer detection device for multiple terrains and a method for using the same. Summary of the Invention

[0017] The inner rotating rod is divided into a straight rod in the lower half and a spline rod in the upper half. The length of the straight rod is adjustable. The maximum telescopic length of the straight rod is the same as the maximum descending distance of the push block. A third driven gear connected by a spline is provided on the outer side of the spline rod. A third drive gear fixedly connected to the second motor shaft is provided. The third drive gear is meshed with the third driven gear.

[0018] A rotatable top ring is provided at the top end of the spline rod, and pull rods are provided on both sides of the top ring.

[0019] Preferably, a rotatable fourth electric cylinder and a rotating beam are further provided inside the second cavity, one end of the rotating beam is rotatably connected to the inside of the second cavity, the other end of the rotating beam is rotatably connected to the telescopic end of the fourth electric cylinder, and the tail end of the fourth electric cylinder is rotatably connected to the inside of the second cavity. When the fourth electric cylinder is started, it pushes the rotating beam to rotate and lift.

[0020] A long slot is provided inside the rotating beam, and the pull rods on both sides of the top ring are inserted into the long slot and slidably connected thereto. When one end of the rotating beam is lifted, the pull rod, the top ring, the spline rod and the straight rod are pulled up synchronously through the long slot, and vice versa.

[0022] Preferably, the interior of the sampling cone head is also provided with an axially arranged first through hole, the first through hole is arranged coaxially with the loading tube, the bottom end of the straight rod in the lower half of the inner rotating rod is fixedly connected coaxially with the sealing disk, and the lower end of the sealing disk is fixedly connected to the sampling cone head.

When the sealing disk rotates, the opening at the bottom end of the loading tube moves from being coaxial with the second through hole to being coaxial with the rubber tube plug.

[0024] A method for using a soil layer detection device for multiple terrains comprises the following steps:

[0025] Step 1: First determine the location where soil testing and sampling is required, place the soil layer testing equipment on the ground, choose whether to install the pointed cone positioning column according to the terrain, and then fix the rectangular frame and start soil sampling;

[0026] Step 2: Install the loading tube into the U-shaped slot, clamp it with the C-shaped clip, insert the insert into the sliding clip, place the rubber tube plug into the inner groove at the other end of the arc waist slot, connect the sealing disk to the lower end of the inner rotating rod, then put the sampling shell on the outside of the sampling inner core and fix it, and finally fix the sampling cone head to the sealing disk. At this time, the loading tube, the second through hole, and the first through hole are coaxially arranged;

[0027] Step 3: Adjust the burial angle and position of the sampling assembly as needed. The electric slide, lifting plate, side drive assembly, and rotary drive assembly drive the sampling assembly to adjust. After the inclination sensor determines that the angle adjustment of the sampling assembly is completed, the sampling assembly is started.

[0028] Step 4: The first motor is started to drive the external threaded rod to rotate, and the external threaded rod pushes the pushing block, the pushing column, the sampling inner core, the sampling outer shell, the sampling cone head, and the sealing disk to descend. The straight rod at the lower half of the inner rotating rod is lengthened, and the sampling cone head, the sampling outer shell, and the sampling inner core enter the soil layer. The collected soil layer enters the loading tube through the first through hole and the second through hole. After reaching the maximum depth, the external threaded rod stops rotating, and the straight rod is extended to its maximum length.

[0029] Step 5: The second motor is started to drive the inner rotating rod to rotate. When the inner rotating rod rotates, the sealing disk is driven to rotate synchronously, so that the second through-hole rotates away, and the rubber tube plug rotates to the opening below the loading tube. Then the fourth electric cylinder is started to push the rotating beam to lift up, and the rotating beam pulls the inner rotating rod to rise. Since the straight rod at the lower half of the inner rotating rod is extended to its maximum length, the inner rotating rod hard pulls the sealing disk and the sampling cone head to rise. When the sealing disk rises, the loading tube is pushed up synchronously, and the elastic telescopic column contracts. When the elastic telescopic column contracts to the minimum value, the loading tube cannot continue to retreat, and the rubber tube plug is inserted into the lower end opening of the loading tube to seal the loading tube.

[0030] Step 6. The fourth electric cylinder drives the rotating beam to reverse and return to its original position. The sealing plate and the sampling cone head descend, and the elastic telescopic column pushes the loading tube to descend synchronously. Then the first motor starts to reverse, driving the external threaded rod, the pushing block, the sampling inner core, the sampling outer shell, the sampling cone head, the loading tube, and the sealing plate to rise and return to their original position. After leaving the soil layer, remove the fasteners on the outside of the sampling outer shell, take off the sampling outer shell, and remove the loading tube filled with sampled soil from the U-shaped slot.

[0031] The present invention provides a soil layer detection device for multiple terrains and its use method.

[0032] Beneficial effects:

[0033] 1. The soil layer detection equipment for multi-terrain of the present invention can operate stably, safely and efficiently on complex terrains such as steep slopes, soft ground, rugged mountains, woodlands, etc., where traditional equipment is difficult to operate; it realizes rapid and precise adjustment of the sampling angle within a large range and is easy to operate; after the sampling is completed, the obtained soil core or sample can be immediately and automatically packaged and sealed in situ at the sampling point to maintain the original state of the sample to the greatest extent; it has a high degree of automation and greatly simplified the operation process, which significantly reduces the requirements for the physical strength and professional skills of the operator and improves the overall operation efficiency.

[0034] 2. The soil layer detection equipment for multi-terrain of the present invention collects soil layers through the first through hole and the second through hole when in use, and enters the loading tube after reaching the maximum depth. The external threaded rod stops rotating at this time, and the straight tube rod is extended to the maximum length; the second motor starts to drive the inner rotating rod to rotate, and when the inner rotating rod rotates, it drives the sealing disk to rotate synchronously, so that the second through hole rotates away, and the rubber tube plug rotates to the opening below the loading tube, and then the fourth electric cylinder is started to push the rotating beam to lift, and the rotating beam pulls the inner rotating rod to rise. Since the straight tube rod of the lower half of the inner rotating rod is extended to the maximum length, the inner rotating rod hard pulls the sealing disk and the sampling cone head to rise, and the sealing disk pushes the loading tube to rise synchronously when it rises, and the elastic telescopic column contracts. When the elastic telescopic column contracts to the minimum value, the loading tube cannot continue to retreat, and the rubber tube plug is inserted into the inner opening of the lower end of the loading tube to seal the loading tube. The operation is fast and stable, and the applicability is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The inner rotating rod 65 is divided into a straight rod in the lower half and a spline rod 651 in the upper half. The straight rod can be extended but not rotated. The maximum extension length of the straight rod is the same as the maximum descending distance of the push block 63.

[0065] A rotatable top ring is provided at the top of the spline rod 651, and pull rods are provided on both sides of the top ring. Pulling the pull rods can pull the inner rotating rod 65 upward. At the same time, when the straight rod and the spline rod 651 in the inner rotating rod 65 rotate synchronously, the top ring will not rotate accordingly.

When the sealing disk 610 rotates, the bottom end opening of the loading tube 69 moves from being coaxial with the second through hole 6102 to being coaxial with the rubber tube plug 6103.

[0073] Example 2:

[0074] This embodiment provides a method for using a soil layer detection device for multiple terrains, including the following steps:

[0075] Step 1: First determine the location where soil testing and sampling is required, place the soil layer testing equipment on the ground, choose whether to install the pointed cone positioning column 11 according to the terrain, and then fix the rectangular frame 1 and perform soil layer sampling;

[0076] Step 2: Install the loading tube 69 into the U-shaped slot 661, clamp it with the C-shaped clamping strip 662, insert the inserting strip 691 into the sliding clamping strip 664, place the rubber tube plug 6103 into the inner groove at the other end of the arc waist slot 6101, connect the sealing disk 610 to the lower end of the inner rotating rod 65, then put the sampling shell 67 on the outside of the sampling inner core 66 and fix it, and finally fix the sampling cone head 68 to the sealing disk 610. At this time, the loading tube 69, the second through hole 6102, and the first through hole 681 are arranged coaxially;

[0077] Step 3: Adjust the burial angle and position of the sampling assembly 6 as needed. The electric slide 3, the lifting plate 21, the side drive assembly 4, and the rotary drive assembly 5 drive the sampling assembly 6 to adjust. After the inclination sensor 62 determines that the angle adjustment of the sampling assembly 6 is completed, the sampling assembly 6 is started.

[0078] Step 4: The first motor 642 is started to drive the external threaded rod 64 to rotate. The external threaded rod 64 pushes the pushing block 63, the pushing column 631, the sampling inner core 66, the sampling outer shell 67, the sampling cone head 68, and the sealing disk 610 to descend. The straight rod at the lower half of the internal rotating rod 65 is extended. The sampling cone head 68, the sampling outer shell 67, and the sampling inner core 66 enter the soil layer. The collected soil layer enters the loading tube 69 through the first through hole 681 and the second through hole 6102. After reaching the maximum depth, the external threaded rod 64 stops rotating. At this time, the straight rod is extended to its maximum length.

[0079] Step 5, the second motor 653 is started to drive the inner rotating rod 65 to rotate, and when the inner rotating rod 65 rotates, the sealing disk 610 is driven to rotate synchronously, so that the second through hole 6102 rotates away, and the rubber tube plug 6103 rotates to the opening below the loading tube 69, and then the fourth electric cylinder 655 is started to push the rotating beam 654 to lift, and the rotating beam 654 pulls the inner rotating rod 65 to rise. Since the straight rod at the lower half of the inner rotating rod 65 is extended to the maximum length, the inner rotating rod 65 hard pulls the sealing disk 610 and the sampling cone head 68 to rise. When the sealing disk 610 rises, it pushes the loading tube 69 to rise synchronously, and the elastic telescopic column 663 contracts. When the elastic telescopic column 663 contracts to the minimum value, the loading tube 69 can no longer retreat, and the rubber tube plug 6103 is inserted into the lower end opening of the loading tube 69 to seal the loading tube 69;

A method for using the soil layer detection device for multiple terrains according to claim 8, characterized in that: The following steps are involved: Step 1: First determine the location where soil testing and sampling is required, place the soil layer testing equipment on the ground, choose whether to install the pointed cone positioning column (11) according to the terrain, and then fix the rectangular frame (1) and perform soil layer sampling; Step 2: Install the loading tube (69) into the U-shaped slot (661), clamp it with the C-shaped clip (662), insert the insert strip (691) into the sliding clip (664), put the rubber tube plug (6103) into the inner groove at the other end of the arc waist slot (6101), connect the sealing disk (610) with the lower end of the inner rotating rod (65), and then put the sampling shell (67) on the outside of the sampling inner core (66) to fix it. Finally, fix the sampling cone head (68) with the sealing disk (610). At this time, the loading tube (69), the second through hole (6102), and the first through hole (681) are coaxially arranged; Step 3: Adjust the burial angle and position of the sampling assembly (6) according to the requirements. The electric slide (3), the lifting plate (21), the side drive assembly (4), and the rotary drive assembly (5) drive the sampling assembly (6) to adjust. After the inclination sensor (62) determines that the angle adjustment of the sampling assembly (6) is completed, the sampling assembly (6) is started. Step 4: The first motor (642) is started to drive the external threaded rod (64) to rotate. The external threaded rod (64) pushes the pushing block (63), the pushing column (631), the sampling inner core (66), the sampling outer shell (67), the sampling cone head (68), and the sealing disk (610) to descend. The straight rod at the lower half of the internal rotating rod (65) is stretched. The sampling cone head (68), the sampling outer shell (67), and the sampling inner core (66) enter the soil layer. The collected soil layer enters the loading pipe (69) through the first through hole (681) and the second through hole (6102). After reaching the maximum depth, the external threaded rod (64) stops rotating. At this time, the straight rod is stretched to its maximum length. Step 5: The second motor (653) starts to drive the inner rotating rod (65) to rotate. When the inner rotating rod (65) rotates, the sealing plate (610) rotates synchronously, so that the second through hole (6102) rotates away, and the rubber tube plug (6103) rotates to the opening below the loading tube (69). Then the fourth electric cylinder (655) starts to push the rotating beam (654) to lift up. The rotating beam (654) pulls the inner rotating rod (65) up. As the inner rotating rod (65) moves down, The half of the straight rod is extended to its maximum length. At this time, the inner rotating rod (65) pulls the sealing disc (610) and the sampling cone head (68) upward. When the sealing disc (610) rises, it pushes the loading tube (69) to rise synchronously. The elastic telescopic column (663) contracts. When the elastic telescopic column (663) contracts to the minimum value, the loading tube (69) cannot move back further. The rubber tube plug (6103) is inserted into the lower opening of the loading tube (69) to seal the loading tube (69). Step 6: The fourth electric cylinder (655) drives the rotating beam (654) to reverse and return to its original position, the sealing disk (610) and the sampling cone head (68) descend, and the elastic telescopic column (663) pushes the loading tube (69) to descend synchronously, and then the first motor (642) starts to reverse, driving the external threaded rod (64), the pushing block (63), the sampling inner core (66), the sampling shell (67), the sampling cone head (68), the loading tube (69), and the sealing disk (610) to rise and return to their original position. After leaving the soil layer, the fastener (671) on the outside of the sampling shell (67) is removed, the sampling shell (67) is taken off, and the loading tube (69) filled with sampled soil is removed from the U-shaped slot (661).
