Description

Technical Field

[0001] This invention relates to the field of high fill compaction degree testing technology, specifically to an automated device and method for testing the compaction degree of high fill. Background Technology

[0002] With the acceleration of urbanization in my country, the Northwest region often meets the needs of urban construction land by cutting mountains and filling gullies in hilly areas, resulting in a large number of high-fill foundations. The safety and stability of buildings and structures built on high-fill foundations largely depend on the filling and compaction quality of the high-fill foundation. Compaction degree, as one of the key indicators for foundation filling construction quality testing, characterizes the density of the foundation after compaction. Currently, the main on-site testing methods for foundation compaction degree include sand cone method, ring cutter method, water filling method, and nuclear moisture density meter method. However, the above-mentioned test methods have many shortcomings: 1. On-site... 1. Compaction degree testing must be conducted after compaction, which is a post-construction inspection and control method. Problems discovered during testing are difficult to address in a timely manner during compaction. 2. On-site compaction degree testing significantly interferes with the filling construction, especially when testing the filling quality of deep foundations. Large test pits need to be dug, which takes a long time and extends the construction period. 3. Due to the randomness and limitations of the selected sampling points, the test results cannot fully reflect the compaction quality of the entire area. When the data from individual test points do not meet the compaction degree control requirements, it is difficult to determine the area that needs to be re-compacted.

[0003] Existing automated compaction testing devices and methods for high fills have structural design flaws. These flaws include the problem that downward soil sampling pits can lead to localized soil compaction, resulting in overestimated compaction values, and the excessive workload for workers when testing compaction at multiple points. Summary of the Invention

[0004] This invention provides an automated device and method for detecting the compaction degree of high-fill embankments, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated device and method for detecting the compaction degree of high-fill embankments, comprising...

[0006] A tracked device, wherein a vehicle body is fixedly connected to the surface of the tracked device, a protective frame is fixedly connected to the middle position of the inner side of the vehicle body, and a bottom plate is fixedly connected to the lower position of the inner side of the protective frame.

[0007] An anti-compaction mechanism is installed on the top of a base plate. A hole is opened on the surface of the base plate near the anti-compaction mechanism. The bottom end of the anti-compaction mechanism passes through the hole and extends to the lower part of the base plate. The bottom end of the anti-compaction mechanism impacts downward into the lower part of the ground for soil extraction. The mechanism includes a mechanism wall. A driving component is fixedly connected to the top of the mechanism wall. A soil extraction cylinder is fixedly connected to the inner side of the driving component. A pressing component is fixedly connected to the bottom of the soil extraction cylinder.

[0008] The lowering mechanism is located at the center of the top of the base plate and is used to apply external force to the soil sampling cylinder, causing the soil sampling cylinder to move downward into the lower position of the ground. The driving component supports the soil sampling cylinder, and a stabilizing ring is fixedly connected to the top of the soil sampling cylinder. Multiple soil sampling cylinders are provided, and the lowering mechanism can rotate intermittently to apply external force to multiple soil sampling cylinders respectively.

[0009] Preferably, the driving component includes a first motor, the bottom of which is fixedly connected to the top of the mechanism wall, and a lead screw is fixedly connected to the output end of the first motor. The driving component supports the soil sampling cylinder so that the soil sampling cylinder is inside the protective frame in the initial state, and the mechanism wall supports the driving component.

[0010] Preferably, the surface of the lead screw is threaded with a threaded block, the surface of the threaded block is fixedly connected with a connecting hook, and the end of the connecting hook away from the threaded block is fixedly connected to the surface of the soil sampling cylinder.

[0011] Preferably, the pressing component includes an alloy ring, the top of which is fixedly connected to the bottom of the soil sampling cylinder. A second motor is fixedly connected to the top of the alloy ring. Before soil sampling, the first motor is energized to drive the lead screw to rotate. The lead screw, through its thread, causes the threaded block to be positioned above the inner side of the mechanism wall, and the alloy ring to be positioned above the ground.

[0012] Preferably, the output shaft of the second motor is fixedly connected to a connecting shaft, and a rotating disk is fixedly connected to the surface of the connecting shaft. There are two second motors.

[0013] Preferably, the labor reduction mechanism includes an intermittent component, the bottom of which is fixedly connected to the middle of the top of the base plate, and an extension rod is fixedly connected to the inner side of the intermittent component. The extension rod supports the platform, so that the platform is positioned above the soil sampling cylinder. The tracked equipment drives the vehicle to move, and the intermittent component intermittently drives the extension rod to rotate. Hydraulic pressure is supplied to the inside of the cylinder.

[0014] Preferably, a platform is fixedly connected to the top end of the extension rod, a cylinder is fixedly connected to the top of the platform, a plunger rod is slidably connected to the inner side of the cylinder, and an impact assembly is fixedly connected to the top of the cylinder.

[0015] Preferably, the intermittent assembly includes a housing, the bottom of which is fixedly connected to the middle of the top of the base plate, and a top cover is fixedly connected to the top of the housing. A worm gear is externally connected to a drive device to rotate it. The surface of the worm gear meshes with the surface of the worm wheel. The worm wheel rotates on the inner side of the housing. The restriction of the top cover makes the rotation of the worm wheel more stable. The worm wheel drives the extension rod to rotate.

[0016] Preferably, a worm gear is rotatably connected to the inner side of the housing, and a worm is rotatably connected to the surface of the housing near the side. The inner side of the worm gear is fixedly connected to the lower part of the surface of the extension rod.

[0017] Preferably, the impact assembly includes a cavity, which is located above the inner side of the cylinder body. An elastic sheet is fixedly connected to the inner side of the cylinder body near the cavity. Hydraulic fluid is introduced into the injection pipe, and a pressure valve blocks the hydraulic fluid. The elastic sheet is pushed by the hydraulic fluid to expand towards the cavity, and the internal elastic potential energy of the elastic sheet gradually increases.

[0018] Preferably, a liquid injection pipe is fixedly connected to the top of the cylinder, a pressure valve is fixedly connected to the upper part of the inner side of the cylinder, and the elastic sheet is made of rubber.

[0019] Preferably, a method for automated testing of compaction degree in high-fill embankments includes the following steps:

[0020] Step 1: Before soil extraction, the first motor is powered on and drives the lead screw to rotate. The lead screw, through the thread, makes the threaded block positioned above the inner side of the mechanism wall. The mechanism wall supports the driving component. The lowering mechanism moves to the position directly above the soil extraction cylinder. The lowering mechanism applies pressure to the soil extraction cylinder, and the stabilizing ring guides the pressure, so that the soil extraction cylinder is moved downward steadily. The bottom of the lowering component is driven to drill into the lower part of the ground.

[0021] Step 2: During soil extraction, the soil extraction cylinder is driven to move downwards. The threaded block drives the screw to rotate through the thread, and the threaded block slides downwards, allowing the alloy ring to enter the soil. The contact area between the alloy ring and the soil is small, and the rotating disk is perpendicular to the ground and experiences minimal resistance. When the alloy ring is below the ground, the second motor drives the rotating disk to rotate, and the soil is sealed inside the soil extraction cylinder, completing the soil extraction process.

[0022] Step 3, Enhancement: When the hydraulic pressure exceeds the pressure threshold of the pressure valve, hydraulic pressure is ejected through the pressure valve. The hydraulic pressure quickly pushes the plunger rod downward. The first motor is a magnetic levitation motor. At this time, the first motor is not powered. The lead screw rotates freely, causing the threaded block to slide downward on the inner side of the mechanism wall. The soil sampling cylinder is pushed into the lower part of the ground. The impact force makes it difficult for the soil to be squeezed when the soil sampling cylinder is sampling soil.

[0023] Step 4: Repeat soil sampling. The platform is positioned above the soil sampling cylinder. The tracked equipment moves the vehicle, and the intermittent component intermittently rotates the extension rod. Hydraulic pressure is introduced into the cylinder, which pushes the plunger rod downward to impact the top of the soil sampling cylinder. The soil sampling cylinder is pushed downward, and the pressing component is pressed into the lower part of the ground to collect soil. As the vehicle moves, multiple soil sampling cylinders collect soil samples from multiple locations on the ground for testing.

[0024] This invention provides an automated device and method for detecting the compaction degree of high-fill embankments. It has the following beneficial effects:

[0025] 1. The automated compaction testing device and method for high fills involves a lowering mechanism that moves to the top of the sampling cylinder when soil needs to be taken from the ground. The lowering mechanism applies pressure to the sampling cylinder, and the stabilizing ring guides the pressure, causing the sampling cylinder to move steadily downward. The bottom of the pressing component is driven to drill into the lower part of the ground. The cylindrical structure of the sampling cylinder and the pressing component can effectively reduce the compression of the soil, solving the problem that the soil is locally compacted when the soil is taken downward, resulting in an overestimation of the compaction value.

[0026] 2. The automated compaction detection device and method for high fills involves the following steps: During soil extraction, the soil extraction cylinder is driven to move downwards, and the threaded block drives the screw to rotate via the thread. The threaded block slides downwards, allowing the alloy ring to enter the soil. The contact area between the alloy ring and the soil is small, and the rotating disk experiences minimal resistance due to its perpendicularity to the ground. When the alloy ring is below the ground, the second motor drives the rotating disk to rotate, sealing the soil inside the soil extraction cylinder and completing the soil extraction process, thereby effectively reducing soil compression.

[0027] 3. The automated compaction testing device and method for high fill uses hydraulically driven plunger rods to move downwards and impact the top of the soil sampling cylinder. The soil sampling cylinder is pushed downwards, and the pressing component is pressed into the lower part of the ground to collect soil. The number of soil sampling cylinders is set to several. As the vehicle moves, multiple soil sampling cylinders collect soil from multiple locations on the ground for testing, which solves the problem of excessive labor intensity for workers when conducting compaction testing at multiple points.

[0028] 4. The automated compaction detection device and method for high fill has an extension rod with a rotatable connection between the lower part of the extension rod surface and the inner side of the top cover. The rotation of the extension rod causes the cylinder to move to the position above the soil sampling cylinder. Hydraulic pressure is injected into the cylinder from top to bottom. The hydraulic pressure pushes the plunger rod to move downward to impact the soil sampling cylinder. The soil sampling cylinder moves downward to collect soil. Hydraulic pressure is supplied to the lower part of the cylinder to reset the soil sampling cylinder, thereby quickly collecting soil from multiple locations.

[0029] 5. In this automated high-fill compaction detection device and method, when the hydraulic pressure exceeds the pressure threshold of the pressure valve, hydraulic pressure is ejected through the pressure valve, and the hydraulic pressure quickly pushes the plunger rod downward. The first motor is a magnetic levitation motor. At this time, the first motor is not energized, and the lead screw rotates freely, causing the threaded block to slide downward on the inner side of the mechanism wall. The soil sampling cylinder is pushed into the lower position of the ground. The soil sampling cylinder is quickly impacted into the lower position of the ground, and the impact force makes it difficult for the soil to be squeezed when the soil sampling cylinder takes soil.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 2-4 As shown, the present invention provides a technical solution: an automated device and method for detecting the compaction degree of high-fill embankments, comprising...

[0042] Tracked equipment 1, a vehicle body 2 is fixedly connected to the surface of tracked equipment 1, a protective frame 3 is fixedly connected to the middle position of the inner side of the vehicle body 2, and a bottom plate 4 is fixedly connected to the lower position of the inner side of the protective frame 3.

[0043] An anti-compaction mechanism 5 is installed on the top of the base plate 4. A hole is opened on the surface of the base plate 4 near the anti-compaction mechanism 5. The bottom end of the anti-compaction mechanism 5 passes through the hole and extends to the lower part of the base plate 4. The bottom end of the anti-compaction mechanism 5 impacts downward into the lower part of the ground for soil extraction. It includes a mechanism wall 51. A driving component 52 is fixedly connected to the top of the mechanism wall 51. A soil extraction cylinder 53 is fixedly connected to the inner side of the driving component 52. A pressing component 55 is fixedly connected to the bottom of the soil extraction cylinder 53.

[0044] The lowering mechanism 6 is located at the middle of the top of the base plate 4. It is used to apply external force to the soil sampling cylinder 53, so that the soil sampling cylinder 53 moves downward into the position below the ground. The component 52 supports the soil sampling cylinder 53. The top of the soil sampling cylinder 53 is fixedly connected to a stabilizing ring 54. Multiple soil sampling cylinders 53 are provided. The lowering mechanism 6 can rotate intermittently to apply external force to multiple soil sampling cylinders 53 respectively.

[0045] In use, the drive component 52 supports the soil sampling cylinder 53, so that the soil sampling cylinder 53 is inside the protective frame 3 in the initial state. The mechanism wall 51 supports the drive component 52. When it is necessary to take soil from the ground, the lowering mechanism 6 moves to the position directly above the soil sampling cylinder 53. The lowering mechanism 6 applies pressure to the soil sampling cylinder 53, and the stabilizing ring 54 guides the pressure, so that the soil sampling cylinder 53 is moved downward steadily. The bottom of the pressing component 55 is driven to drill into the lower position of the ground. The cylindrical structure of the soil sampling cylinder 53 and the pressing component 55 can effectively reduce the compression of the soil, and solve the problem that the soil will be locally compacted when the soil is taken downward, resulting in an excessively large compaction value.

[0046] like Figure 4 , Figure 5 , Figure 6As shown, the driving component 52 includes a first motor 521, the bottom of which is fixedly connected to the top of the mechanism wall 51. A lead screw 522 is fixedly connected to the output end of the first motor 521. A threaded block 523 is threadedly connected to the surface of the lead screw 522. A connecting hook 524 is fixedly connected to the surface of the threaded block 523. The end of the connecting hook 524 away from the threaded block 523 is fixedly connected to the surface of the soil sampling cylinder 53. The pressing component 55 includes an alloy ring 551, the top of which is fixedly connected to the bottom of the soil sampling cylinder 53. A second motor 552 is fixedly connected to the top of the alloy ring 551. A connecting shaft 553 is fixedly connected to the shaft at the output end of the second motor 552. A rotating disk 554 is fixedly connected to the surface of the connecting shaft 553. There are two second motors 552.

[0047] During use, before soil extraction, the first motor 521 is energized to drive the lead screw 522 to rotate. The lead screw 522, through its thread, positions the threaded block 523 above the inner side of the mechanism wall 51, while the alloy ring 551 is positioned above the ground. During soil extraction, the soil extraction cylinder 53 is driven to move downwards. The threaded block 523, through its thread, drives the lead screw 522 to rotate, and slides downwards, allowing the alloy ring 551 to enter the soil. The contact area between the alloy ring 551 and the soil is small, and the rotating disk 554, perpendicular to the ground, experiences minimal resistance. When the alloy ring 551 is below the ground, the second motor 552 drives the rotating disk 554 to rotate, sealing the soil inside the soil extraction cylinder 53, thus completing the soil extraction process and effectively reducing soil compression.

[0048] like Figure 4 , Figure 7 As shown, a drive assembly 52 is fixedly connected to the top of the mechanism wall 51, a soil sampling cylinder 53 is fixedly connected to the inner side of the drive assembly 52, and a pressing assembly 55 is fixedly connected to the bottom of the soil sampling cylinder 53; the drive assembly 52 supports the soil sampling cylinder 53, and a stabilizing ring 54 is fixedly connected to the top of the soil sampling cylinder 53. Multiple soil sampling cylinders 53 are provided. The labor-reducing mechanism 6 can rotate intermittently to apply external force to multiple soil sampling cylinders 53 respectively. The labor-reducing mechanism 6 includes an intermittent assembly 61. The bottom of the intermittent assembly 61 is fixedly connected to the middle position of the top of the base plate 4. An extension rod 62 is fixedly connected to the inner side of the intermittent assembly 61. A platform 63 is fixedly connected to the top of the extension rod 62. A cylinder 64 is fixedly connected to the top of the platform 63. A plunger rod 65 is slidably connected to the inner side of the cylinder 64. An impact assembly 66 is fixedly connected to the top of the cylinder 64.

[0049] In use, the extension rod 62 supports the platform 63, positioning the platform 63 above the soil sampling cylinder 53. The tracked device 1 moves the vehicle body 2, and the intermittent component 61 intermittently rotates the extension rod 62. Hydraulic pressure is introduced into the cylinder 64, which pushes the plunger rod 65 downward to impact the top of the soil sampling cylinder 53. The soil sampling cylinder 53 is pushed downward, and the pressing component 55 is pressed into the ground below to collect soil. Several soil sampling cylinders 53 are provided. As the vehicle body 2 moves, multiple soil sampling cylinders 53 collect soil from multiple locations on the ground for testing, solving the problem of excessive labor intensity for workers when testing the compaction at multiple points.

[0050] like Figure 7 , Figure 8 , Figure 9 As shown, the intermittent assembly 61 includes a housing 611, the bottom of which is fixedly connected to the middle of the top of the base plate 4, a top cover 612 fixedly connected to the top of the housing 611, a worm gear 614 rotatably connected to the inner side of the housing 611, a worm 613 rotatably connected to the surface of the housing 611 near the side, and the inner side of the worm gear 614 fixedly connected to the lower part of the surface of the extension rod 62. The impact assembly 66 includes a cavity 661, which is opened above the inner side of the cylinder 64. An elastic sheet 662 is fixedly connected to the inner side of the cylinder 64 near the cavity 661, an injection pipe 663 is fixedly connected to the top of the cylinder 64, and a pressure valve 664 is fixedly connected to the upper part of the inner side of the cylinder 64. The elastic sheet 662 is made of rubber.

[0051] In use, the worm gear 613 is externally driven by the device to rotate. The surface of the worm gear 613 meshes with the surface of the worm wheel 614. The worm wheel 614 rotates on the inner side of the housing 611. The restriction of the top cover 612 makes the rotation of the worm wheel 614 more stable. The worm wheel 614 drives the extension rod 62 to rotate. The lower part of the surface of the extension rod 62 is rotatably connected to the inner side of the top cover 612. The rotation of the extension rod 614 causes the cylinder 64 to move to the position above the soil sampling cylinder 53. Hydraulic pressure is injected into the cylinder 64 from top to bottom. The hydraulic pressure pushes the plunger rod 65 to move downward to impact the soil sampling cylinder 53. The soil sampling cylinder 53 moves downward to collect soil. Hydraulic pressure is then introduced into the lower part of the cylinder 64, and the soil sampling cylinder 53 is reset, thereby quickly collecting soil from multiple locations.

[0052] like Figure 5 , Figure 9As shown, the bottom of the first motor 521 is fixedly connected to the top of the mechanism wall 51. The output end of the first motor 521 is fixedly connected to a lead screw 522. A threaded block 523 is threadedly connected to the surface of the lead screw 522. A connecting hook 524 is fixedly connected to the surface of the threaded block 523. The end of the connecting hook 524 away from the threaded block 523 is fixedly connected to the surface of the soil sampling cylinder 53. The cavity 661 is opened above the inner side of the cylinder 64. An elastic sheet 662 is fixedly connected to the inner side of the cylinder 64 near the cavity 661. An injection pipe 663 is fixedly connected to the top of the cylinder 64. A pressure valve 664 is fixedly connected to the upper part of the inner side of the cylinder 64. The elastic sheet 662 is made of rubber.

[0053] In use, hydraulic pressure is introduced into the injection pipe 663, and the pressure valve 664 blocks the hydraulic pressure. The elastic plate 662 is pushed by the hydraulic pressure to expand towards the cavity 661. The internal elastic potential energy of the elastic plate 662 gradually increases. When the hydraulic pressure exceeds the pressure threshold of the pressure valve 664, the hydraulic pressure is ejected through the pressure valve 664. The hydraulic pressure quickly pushes the plunger rod 65 downward. The first motor 521 is a magnetic levitation motor. At this time, the first motor 521 is not energized. The lead screw 522 rotates freely, causing the threaded block 523 to slide downward on the inner side of the mechanism wall 51. The soil sampling cylinder 53 is pushed into the lower part of the ground. The impact force makes it difficult for the soil to be squeezed when the soil sampling cylinder 53 is sampling soil.

[0054] like Figures 1-9 As shown, a method for automated detection of compaction degree in high-fill embankments includes the following steps:

[0055] Step 1: Before soil extraction, the first motor 521 is energized to drive the lead screw 522 to rotate. The lead screw 522, through its threads, causes the threaded block 523 to be positioned above the inner side of the mechanism wall 51. The mechanism wall 51 supports the driving component 52. The lowering mechanism 6 moves to the position directly above the soil extraction cylinder 53. The lowering mechanism 6 applies pressure to the soil extraction cylinder 53. The stabilizing ring 54 guides the pressure, causing the soil extraction cylinder 53 to be moved downward in a stable manner. The bottom of the lowering component 55 is driven to drill into the lower part of the ground.

[0056] Step 2: During soil extraction, the soil extraction cylinder 53 is driven to move downwards. The threaded block 523 drives the lead screw 522 to rotate through the thread, while the threaded block 523 slides downwards, allowing the alloy ring 551 to enter the soil. The contact area between the alloy ring 551 and the soil is small, and the rotating disk 554 is perpendicular to the ground and experiences minimal resistance. When the alloy ring 551 is below the ground, the second motor 552 drives the rotating disk 554 to rotate, and the soil is sealed inside the soil extraction cylinder 53, completing the soil extraction process.

[0057] Step 3, Enhancement: When the hydraulic pressure exceeds the pressure threshold of the pressure valve 664, hydraulic pressure is ejected through the pressure valve 664. The hydraulic pressure quickly pushes the plunger rod 65 downward. The first motor 521 is a magnetic levitation motor. At this time, the first motor 521 is not energized. The lead screw 522 rotates freely, causing the threaded block 523 to slide downward on the inner side of the mechanism wall 51. The soil sampling cylinder 53 is pushed into the lower part of the ground. The impact force makes it difficult for the soil to be squeezed when the soil sampling cylinder 53 is sampling soil.

[0058] Step 4: Repeat soil sampling. The platform 63 is positioned above the soil sampling cylinder 53. The tracked device 1 drives the vehicle body 2 to move. The intermittent component 61 intermittently drives the extension rod 62 to rotate. Hydraulic pressure is introduced into the cylinder 64. The hydraulic pressure pushes the plunger rod 65 downward to impact the top of the soil sampling cylinder 53. The soil sampling cylinder 53 is pushed downward, and the pressing component 55 is pressed into the lower part of the ground to collect soil. As the vehicle body 2 moves, multiple soil sampling cylinders 53 collect soil from multiple locations on the ground for testing.

7. A method for automatically detecting the compaction degree of high-fill embankments, using the automated compaction degree detection device for high-fill embankments as described in claim 6, characterized in that: Includes the following steps: Step 1: Before soil extraction, the first motor (521) is powered on and drives the lead screw (522) to rotate. The lead screw (522) makes the threaded block (523) above the inner side of the mechanism wall (51) through the thread. The mechanism wall (51) supports the driving component (52). The lowering mechanism (6) moves to the position directly above the soil extraction cylinder (53). The lowering mechanism (6) applies pressure to the soil extraction cylinder (53). The stabilizing ring (54) guides the pressure, so that the soil extraction cylinder (53) is moved downward in a stable manner. The bottom of the lowering component (55) is driven to drill into the lower position of the ground. Step 2: During soil extraction, the soil extraction cylinder (53) is driven to move downwards. The threaded block (523) drives the screw (522) to rotate through the thread. The threaded block (523) slides downwards, allowing the alloy ring (551) to enter the soil. The contact area between the alloy ring (551) and the soil is small, and the rotating disk (554) is perpendicular to the ground and experiences minimal resistance. When the alloy ring (551) is below the ground, the second motor (552) drives the rotating disk (554) to rotate, and the soil is sealed inside the soil extraction cylinder (53), completing the soil extraction process. Step 3, Enhancement: When the hydraulic pressure exceeds the pressure threshold of the pressure valve (664), hydraulic pressure is ejected through the pressure valve (664), and the hydraulic pressure quickly pushes the plunger rod (65) downward. The first motor (521) is a magnetic levitation motor. At this time, the first motor (521) is not powered, and the lead screw (522) rotates freely, causing the threaded block (523) to slide downward on the inner side of the mechanism wall (51). The soil sampling cylinder (53) is pushed into the lower position of the ground. The soil sampling cylinder (53) is quickly impacted into the lower position of the ground. The impact force makes it difficult for the soil to be squeezed when the soil sampling cylinder (53) takes soil. Step 4: Repeated soil sampling. The platform (63) is positioned above the soil sampling cylinder (53). The tracked equipment (1) drives the vehicle body (2) to move. The intermittent component (61) intermittently drives the extension rod (62) to rotate. Hydraulic pressure is introduced into the cylinder (64). The hydraulic pressure pushes the plunger rod (65) to move downward and impact the top of the soil sampling cylinder (53). The soil sampling cylinder (53) is pushed downward and the pressing component (55) is pressed into the lower position of the ground to collect soil. As the vehicle body (2) moves, multiple soil sampling cylinders (53) collect soil from multiple positions on the ground for testing.
