[0002] Soil sampling refers to the method of collecting soil samples, including the layout of the samples and the sampling technology; the collection of soil samples is the basic work in the fields of soil analysis research and geological exploration. By analyzing and studying the soil samples, we can understand the actual condition of the soil. In the fields of civil engineering or agriculture, it is often necessary to investigate the local soil conditions in order to make correct treatment for the area.

[0003] For example, a deep soil sampling device with publication number CN215065410U includes a sampling barrel, a hinged rod, a fixed seat, a positioning ring and a sampling part. One end of the two hinged rods is hinged to the positioning ring, and the other ends of the two hinged rods are hinged to two fixed seats respectively. The sampling barrel is slidably connected to the positioning ring, and the sampling part is slidably connected in the sampling barrel. Circular plates are provided on the two fixed seats.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

When the first connecting rod rotates along the arc hole to the edge of the hole, the connecting disk is driven to rotate. With the cooperation of the annular inclined groove, the connecting disk moves upward during the rotation, thereby driving the second support plate to rotate and rise synchronously. The connecting disk moves to the top of the annular inclined groove, falls under the action of gravity, and contacts the ground again. This solves the problem of insufficient support on the surface of the ground when sampling wetland soil, and the device will sink too deep under the gravity of the device, making it difficult to control the depth of the device. By changing the support position of the first support plate and the second support plate, it is avoided that the device is always in the same position, causing the device to continue to sink, affecting the accuracy of the sampling results.

[0019] 2. The pressure plate is pushed downward by the second connecting rod to squeeze the airbag. The airbag is compressed to expand to both sides, thereby pushing the third support plate from the inside of the second support plate to expand to both sides along the through hole, thereby increasing the support surface of the second support plate and improving the support effect of the device. In the process of the second support plate rising and rotating and contacting the ground again, the problem of insufficient support surface of the second support plate causing the device to sink quickly again is avoided, thereby improving the practicality of the device.

[0020] 3. After drilling to the specified depth, rotate the mandrel, use the second bearing plate to cooperate with the thread of the mandrel to move the mandrel and the connecting sleeve upward, use the second spring to push the baffle to expand, so that the wetland soil enters the sampling box, and then rotate the mandrel downward to drive the baffle to the inside of the feed hole through the pull rope to seal the feed hole, avoiding soil loss, causing sampling failure, and requiring secondary sampling, thereby improving the sampling success rate of the device.

[0032] Example 1: Please refer to Figure 1 - Figure 2 and Figure 4 - Figure 7The present invention provides a technical solution: a deep soil sampling device, comprising two first support plates 1, a second support plate 2 and a first carrying plate 4, the two first support plates 1 are fixedly connected by a connecting plate 11, the second support plate 2 is rotatably connected to the adjacent first support plate 1 by a telescopic rod 3, the top of each telescopic rod 3 is fixedly connected to a scale 31, the side wall of the scale 31 is symmetrically fixedly connected to a first electrode 33, the side wall of the scale 31 is slidably connected to a floating plate 32, the top of the floating plate 32 is symmetrically fixedly connected to a second electrode 34, an adjustment component 5 is installed on the top of the first carrying plate 4, the adjustment component 5 includes a second motor 51, the output end of the second motor 51 is fixedly connected to a second rotating shaft 52, and the side wall of the second rotating shaft 52 is fixedly connected to a third gear 53. The side wall of the first carrying plate 4 is fixedly connected with a threaded sleeve 41, and the bottom wall is rotatably connected with a mounting sleeve 54. The side wall of the threaded sleeve 41 is provided with an annular bevel groove 44, and a connecting plate 57 is movably sleeved on the circumferential outer wall of the threaded sleeve 41. The connecting plate 57 is symmetrically provided with arc holes 59. The connecting plate 57 is slidingly connected to the inner wall of the annular bevel groove 44. The bottom end of the connecting plate 57 is symmetrically fixedly connected with a second connecting rod 58, and each second connecting rod 58 passes through the interior of the second support plate 2. The side wall of the mounting sleeve 54 is fixedly connected with a fourth gear 55, and the bottom end of the fourth gear 55 is fixedly connected to a fixed plate 510. The bottom end of the fixed plate 510 is symmetrically fixedly connected with a first connecting rod 56, and each first connecting rod 56 passes through adjacent arc holes 59 and is fixedly connected to the connecting plate 11.

[0033] In this embodiment, when sampling wet soil, the device is first moved to the sampling location, the two first support plates 1 and the second support plate 2 are placed on the soil surface, and the four legs 411 are rotated to unfold. The entire device is supported by the fixed socket 412. Then, the first motor 46 is started. The first motor 46 rotates the first rotating shaft 47 and the first gear 48. The meshing action between the gears drives the second gear 410 and the threaded rod 42 to rotate. The threaded sleeve 41 and the threaded rod 42 are engaged with each other to rotate the drill bit 8, thereby drilling into the ground surface.

[0034] As the drilling continues to deepen, the first support plate 1 and the second support plate 2 begin to sink. By providing the floating plate 32, the floating plate 32 always floats on the surface of the soil layer and will not sink with the device. A telescopic rod 3 and a scale 31 are provided between the first support plate 1 and the second support plate 2. The scale 31 sinks with the device to mark the sinking distance. When the first electrode 33 on the side wall of the scale 31 contacts the second electrode 34 in the floating plate 32, the second motor 51 is started. The second motor 51 works to rotate the second shaft 52 and the third gear 53, thereby driving the fourth gear 55 to rotate, and the first support plate 1 is rotated through the first connecting rod 56, thereby changing the supporting position of the first support plate 1 and filling the pit caused by the sinking of the first support plate 1 and the second support plate 2 for continuous use.

[0035] When the first connecting rod 56 rotates along the arc-shaped hole 59 to the edge of the hole, it drives the connecting disk 57 to rotate. By setting the annular inclined groove 44, the connecting disk 57 moves upward during the rotation, and then drives the second support plate 2 to rotate and rise synchronously through the second connecting rod 58. The connecting disk 57 moves to the top of the annular inclined groove 44, falls under the action of gravity, and contacts the ground again, so that the supporting position of the second support plate 2 changes by a certain angle, avoiding always being in the same position, causing the device to continue to sink, affecting the sampling results.

[0036] Example 2: Please refer to Figure 2 and Figure 8 The first support plate 1 and the second support plate 2 are arranged in a cross shape. The distance between the two first support plates 1 is greater than the width of the second support plate 2, which will not affect the rotation of the second support plate 2. The floating plate 32 is a bowl-shaped structure. The first electrode 33 and the second electrode 34 are both electrically connected to the second motor 51. The second motor 51 is fixedly connected to the top of the first carrier disk 4. The mounting sleeve 54 is sleeved on the outer wall of the threaded sleeve 41. The third gear 53 and the fourth gear 55 are meshed and connected. The second rotating shaft 52 is rotatably connected to the first carrier disk 4. The side wall of the scale 31 is symmetrically provided with scale lines 35. The first support plate 1 is an L-shaped structure.

[0037] The threaded sleeve 41 is internally threadedly connected to a threaded rod 42, and a circular groove 43 is opened inside the threaded rod 42. The bottom end of the first supporting plate 4 is symmetrically rotatably connected to a plurality of support legs 411, and the side wall of one end of each support leg 411 is fixedly connected to a fixed socket 412. The top of the first supporting plate 4 is symmetrically fixedly connected to a plurality of limit rods 413, and the plurality of limit rods 413 are slidably connected to the second supporting plate 45 together; the threaded rod 42 is rotatably connected to the bottom end of the second supporting plate 45, and the side wall of the threaded rod 42 near one end of the second supporting plate 45 is fixedly connected to a fixed sleeve 49, and the side wall of the fixed sleeve 49 is fixedly connected to a second gear 410, and the top of the second supporting plate 45 is fixedly connected to a first motor 46, and the output end of the first motor 46 is fixedly connected to a first rotating shaft 47, and the first rotating shaft 47 passes through the rear side wall of the second supporting plate 45 and is fixedly connected to a first gear 48, and the first gear 48 is meshed with the second gear 410.

[0038] The inner wall of the second support plate 2 is symmetrically provided with cavities 21, and the inner side wall of each cavity 21 is symmetrically provided with through holes 22. A support assembly 6 is installed inside the cavity 21, and the support assembly 6 includes a pressure plate 61, which is slidably connected to the inner wall of the cavity 21, and the pressure plate 61 is fixedly connected to the second connecting rod 58; the pressure plate 61 is fixedly connected to the top wall of the cavity 21 with a first spring 63, and the first spring 63 is sleeved on the side wall of the second connecting rod 58, and the bottom wall of the cavity 21 is fixedly connected with an airbag 62, and the side wall of the airbag 62 is symmetrically fixedly connected with a push plate 64; a third support plate 65 is slidably connected to the inside of each through hole 22, and the third support plate 65 is fixedly connected to the adjacent push plate 64, and a rectangular hole 66 is provided on the side wall of each third support plate 65, and the telescopic rod 3 passes through the rectangular hole 66.

[0039] In this embodiment, in the process of the second support plate 2 being raised and rotated and contacting the ground again, in order to avoid insufficient supporting surface of the second support plate 2, causing the device to sink quickly again, the second connecting rod 58 pushes the pressure plate 61 downward, so that the pressure plate 61 squeezes the airbag 62, and the airbag 62 is compressed to expand to both sides, thereby pushing the third support plate 65 from the inside of the second support plate 2 to expand to both sides along the through hole 22, thereby increasing the supporting surface of the second support plate 2, improving the supporting effect of the device, and avoiding the device from sinking quickly again. In the process of the second support plate 2 rising, the first spring 63 contracts and resets, driving the airbag 62 to contract, so that the third support plates 65 on both sides are retracted into the inside of the second support plate 2, avoiding affecting one end of the expanded third support plate 65 to limit the first support plate 1.

A second spring 77 is fixedly connected between the connecting sleeve 75 and the adjacent baffle 73, and each second spring 77 is sleeved on the outside of the adjacent pull rope 76.

[0042] In this embodiment: during the soil sampling process, after the soil enters the sampler, it will lack the locking of the sampler baffle 73 during the rising process, and the soil will leak out along the baffle 73, causing the loss of sampled soil and sampling failure, requiring re-sampling, affecting the normal progress of the sampling work; after drilling down to the specified depth, the top rod 74 is rotated, and the second supporting plate 45 is used to cooperate with the thread of the top rod 74 to move the top rod 74 and the connecting sleeve 75 upward, and the second spring 77 is used to reset and push the baffle 73 to expand, so that the wetland soil enters the sampling box 71, and then the top rod 74 is rotated downward, so that the top rod 74 drives the baffle 73 to rotate to the inside of the feed hole 72 through the pull rope 76, and the feed hole 72 is closed to avoid soil loss and the need for secondary sampling, thereby improving the sampling success rate of the device.
