Description

Technical Field

[0001] This utility model relates to the field of environmental governance equipment technology, and more specifically, to a soil sample collection device for soil ecological restoration. Background Technology

[0002] In the field of soil ecological restoration, accurate collection of soil samples is a key prerequisite for assessing pollution status, designing remediation plans, and monitoring remediation effectiveness.

[0003] Currently, most traditional sampling devices are single-tube samplers. When penetrating different soil layers, the collapsed material on the borehole wall and the upper soil carried by the drill bit are easily mixed into the deep sample, resulting in cross-contamination between soil layers. This leads to distorted detection data and seriously interferes with the accuracy of the vertical distribution of pollutants. At the same time, the conventional drill bits used in traditional sampling devices are prone to deflection when encountering hard layers, and the breaking process exacerbates soil structural disturbance, which limits the penetration of hard layers and reduces sampling efficiency. Therefore, in view of this, we have studied and improved the existing structure to provide a soil sample collection device for soil ecological restoration, aiming to achieve a more practical value.

At the same time, the outer cylinder is used to isolate the hole wall from collapse and contamination, while the inner cylinder rotates and presses down. The spiral sampling drill bit is used to rotate the sample into the lower cavity for storage, which effectively avoids cross-contamination between soil layers and improves the authenticity of the test data.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0040] Example:

[0041] Please see Figures 1-4 A soil sample collection device for soil ecological restoration includes a movable base 1, a mounting frame 2 fixedly connected to the top of the movable base 1, two guide rods 3 fixedly connected between the top and bottom inner walls of the mounting frame 2, a movable frame 4 slidably connected to the outer periphery of the guide rods 3, and a sampling mechanism 5 installed on the movable frame 4. In use, the guide rods 3 can limit the position of the sampling mechanism 5 when it moves up and down, preventing positional deviation.

[0042] The sampling mechanism 5 includes a bottom outer cylinder 501 and a sampling motor 508 mounted on a movable frame 4. An extension outer cylinder 502 and a breaking drill bit 503 are threadedly fixed to the top and bottom ends of the bottom outer cylinder 501, respectively. The bottom outer cylinder 501 has an upper cavity 5021 and a lower cavity 5022 inside. A bottom inner cylinder 504 is slidably connected to the upper cavity 5021. A connecting rod 505 is fixedly connected to the bottom end of the bottom inner cylinder 504. The bottom end of the connecting rod 505 extends into the lower cavity 5022 and is fixedly connected to a spiral sampling drill bit 506. An extension inner cylinder 507 is threadedly fixed to the top end of the bottom inner cylinder 504. The top end of the extension inner cylinder 507 extends into the extension outer cylinder 502 and is threadedly fixed to a connecting seat 509. The top end of the connecting seat 509 is connected to the sampling motor 508. The output shaft is connected by a key. During use, the number of extended outer cylinders 502 and extended inner cylinders 507 are set according to the depth of the soil layer being sampled. The length can be extended by threaded connection. At the same time, the breaking drill bit 503 can improve the stability of soil layer penetration, thereby improving the sampling efficiency. The connecting rod 505 and the spiral sampling drill bit 506 work together, and under the rotating and pressing action of the bottom inner cylinder 504, the spiral sampling drill bit 506 can extend into the soil layer being sampled and the sample is spiraled into the lower cavity 5022 for storage, effectively avoiding cross-contamination between soil layers and improving the authenticity of the test data. At the same time, the bottom outer cylinder 501 can support the soil structure at the soil layer position to prevent the hole wall from collapsing and causing contamination.

[0043] See Figure 3Multiple limiting protrusions 5041 are fixedly connected to the outer periphery of the bottom inner cylinder 504. The side wall of the upper cavity 5021 inside the bottom outer cylinder 501 is provided with limiting grooves 5023 corresponding to the positions of the limiting protrusions 5041, and the corresponding limiting protrusions 5041 are slidably connected in the limiting grooves 5023. In use, through the cooperation of the limiting protrusions 5041 and the limiting grooves 5023, the bottom outer cylinder 501 and the bottom inner cylinder 504 can be rotated synchronously. Under the action of the moving frame 4 and the extended inner cylinder 507, the bottom inner cylinder 504, the connecting rod 505 and the spiral sampling drill bit 506 can be driven to rotate and press down, so that the sample can be rotated into the lower cavity 5022 by the spiral sampling drill bit 506 for storage, effectively avoiding cross-contamination of the soil between layers.

[0044] See Figure 2 The movable frame 4 includes an upper sliding seat 401 and a lower sliding seat 402 slidably sleeved on the guide rod 3. A hydraulic cylinder 403 is fixedly connected between the upper sliding seat 401 and the lower sliding seat 402. A sampling motor 508 is fixedly installed on the top of the upper sliding seat 401. Two mutually symmetrical adjustable fixing clamps 404 are fixedly connected to one end of the lower sliding seat 402. A limit sleeve 6 is rotatably connected to the outer circumference of the extended outer cylinder 502, and the two adjustable fixing clamps 404 are clamped and fixed on both sides of the limit sleeve 6. In use, the adjustable fixing clamp 404 consists of a mounting base, an adjusting screw threaded to the mounting base, and a clamping plate fixed to the adjusting screw. By adjusting the adjusting screw and cooperating with the clamping plate, the limit sleeve 6 is clamped and fixed. At this time, the position of the extended outer cylinder 502 can be limited, preventing the extended outer cylinder 502 from moving down with the bottom inner cylinder 504 when the bottom inner cylinder 504 moves down for sampling.

[0045] See Figure 2 The mounting bracket 2 has fixed plates 7 fixedly connected to the top and bottom of one side. A threaded rod 8 is rotatably connected between the two fixed plates 7 through a bearing. A slider 9 is threaded on the outer circumference of the threaded rod 8. One side of the slider 9 is fixedly connected to the sliding seat 402. A lifting motor 10 is installed at the bottom of the upper fixed plate 7. The output shaft of the lifting motor 10 is connected to the top of the threaded rod 8 through a coupling.

[0046] See Figure 2 A protective cover 11 is also fixedly connected to one side of the mounting bracket 2.

[0047] See Figure 2 Two ground anchors 12 are provided at one end of the movable seat 1, two movable wheels 13 are installed at the bottom of the other end of the movable seat 1, and a handrail 14 is fixedly connected to the top of the other end of the movable seat 1.

[0048] When using the equipment: Preliminary work: Move the entire equipment to the sampling point, then use the ground anchor 12 to fix the moving seat 1, and finally conduct a safety inspection of the equipment;

[0049] Installation of sampling mechanism 5: First, thread the top end of the bottom inner cylinder 504 to the extension inner cylinder 507, then put the extension outer cylinder 502 on the outside of the extension inner cylinder 507 and fix the bottom end to the top end of the bottom outer cylinder 501. Next, clamp the adjustable fixing clamp 404 on both sides of the limiting sleeve 6 on the extension outer cylinder 502 to limit the extension outer cylinder 502. At this time, the sampling motor 508 on the upper slide 401 is driven down by the hydraulic cylinder 403 and connected to the top end of the extension inner cylinder 507 through the connecting seat 509.

[0050] Sampling Operation: The sampling motor 508 is started, which drives the extended inner cylinder 507, the bottom inner cylinder 504, the connecting rod 505, and the spiral sampling drill bit 506 to rotate. With the cooperation of the limiting protrusion 5041 and the limiting slide groove 5023, the bottom outer cylinder 501 drives the breaking drill bit 503 to rotate. At this time, the lifting motor 10 is started. Under the action of the threaded rod 8 and the slider 9, the sampling mechanism 5 on the moving frame 4 is moved downwards. Under the action of the rotating breaking drill bit 503, the bottom outer cylinder 501 moves downwards to the designated sampling soil layer position. At this time, the bottom outer cylinder 501 is used to isolate the borehole wall from collapse and contamination. The operation of the rear hydraulic cylinder 403 drives the upper sliding block 401 to move downward, which in turn causes the extended inner cylinder 507 to drive the bottom inner cylinder 504 to rotate and press down. Meanwhile, the spiral sampling drill bit 506 extends out from the perforation at the center of the crushing drill bit 503 from the lower cavity 5022 and spirals into the sampling soil layer. The sample soil is then spiraled into the lower cavity 5022 for storage, which effectively avoids cross-contamination between soil layers and improves the authenticity of the test data. After the sample is taken, the lifting motor 10, together with the threaded rod 8 and the slider 9, lifts the entire sampling mechanism 5 upward again. Finally, the sample soil is spiraled out in the opposite direction using the spiral sampling drill bit 506.
