Description

Technical Field

[0001] The invention relates to the technical field of soil sampling equipment, and in particular to a soil deep processing system for remediating contaminated soil. Background Art

[0002] Soil may be contaminated by a variety of pollutants, such as heavy metals (such as lead, cadmium, mercury, etc.), organic matter (such as pesticides, petroleum hydrocarbons, polycyclic aromatic hydrocarbons, etc.), radioactive substances, and excessive fertilizers and pesticides. These pollutants will reduce soil quality, affect the ecological function of the soil, and threaten the safety of agricultural products and human health. The soil deep treatment system used for contaminated soil remediation mainly collects soil samples at different depths in layers according to the soil depth and soil characteristics, analyzes the conditions of soil samples at different depths, and performs physical or chemical remediation based on the conditions of each layer of soil.

[0003] In the patent document with the published announcement number CN117606849B, a wetland soil collection device is disclosed, which uses a sampling drive module to drive a soil collection tube to gradually insert into the wetland soil during the rotation process, and at the same time uses a knife disc fixedly mounted on the bottom end of the soil collection tube to cooperate with a plurality of fixed knife rods pre-inserted into the wetland soil. As the insertion depth of the soil collection tube increases, the knife disc gradually cuts off the plant residues distributed between the plurality of fixed knife rods, thereby avoiding axial flow mixing of wetland soils at different depths caused by the traction of plant residues as the insertion depth of the soil collection tube increases, thereby ensuring the originality of the material distribution of wetland soils at different depths collected by the device.

[0004] When the above device is in use, there are large gaps between the blades. In a wetland environment or when the land is very soft, the soil is relatively soft. During the rotation of the blades, some rhizomes are cut off or some rhizomes change their current position following the rotation of the blades. At the same time, after the insertion depth of the soil collection tube is positioned, the air pump absorbs the land sample of the current layer accordingly. Due to the change in air pressure, the soil of the current soil layer is absorbed, causing the soft soil layer above to collapse slightly due to the above two situations. The land above can easily fall into the current collection area through the gap between the blades and be adsorbed into the bottle, thereby causing the land sample of the current layer to be mixed with the land above, and the accuracy of sample collection is low.

[0005] Therefore, the present application proposes a soil deep treatment system for contaminated soil remediation. Summary of the invention

[0006] The purpose of the present invention is to address the problem in the background technology that in a wetland environment, the soil is relatively soft, and during the rotation of the blade, some rhizomes are cut off or some rhizomes change their current position as the blade rotates, and the air pressure is affected by the absorption of the collecting bottle, causing the land above to mix with the soil at the current position.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figure 1-Figure 3 As shown, the transmission component 2 is fixedly installed on the top of the transport component 1, and a transmission chain belt 201 is installed on the outer side of the transmission component 2. Two auxiliary threaded rods 202 are installed on both sides of the transmission chain belt 201. The auxiliary threaded rods 202 are rotatably connected above the support platform 101. The transmission component 2 drives the auxiliary threaded rods 202 to rotate through the transmission chain belt 201, causing the two auxiliary threaded rods 202 to rotate along the support platform 101, causing the main support slide plate 301 to move toward the bottom of the ground along the two auxiliary threaded rods 202 until the cutting tool 406 first fits against the upper surface of the ground.

[0039] like Figure 4-Figure 9 As shown, the soil layer setting component 3 also includes a main support slide 301 slidably installed on the support platform 101 through two auxiliary threaded rods 202, a built-in hollow threaded tube 302 is fixedly installed on one side of the main support slide 301, a corresponding support platform 304 is fixedly installed on one side of the built-in hollow threaded tube 302, an auxiliary gear 306 is installed inside the corresponding support platform 304, a hollow threaded transmission tube 303 is slidably installed inside the corresponding support platform 304, and a side of the hollow threaded transmission tube 303 located inside the corresponding support platform 304 is fixedly connected with a gear tooth, and the auxiliary gear 306 is arranged in a meshing state with the gear tooth, and the first electric The first motor and the second motor are both forward and reverse motors. The second motor is fixedly installed on the inner wall of the corresponding support platform 304. The second motor drives the auxiliary gear 306 to rotate. The auxiliary gear 306 drives the hollow threaded transmission tube 303 to rotate by meshing with the gear teeth of the hollow sliding hole 305 where the multi-purpose bottle is placed. The length of the gear teeth is longer than the length of the auxiliary gear 306. The hollow threaded transmission tube 303 moves downward along the built-in hollow threaded tube 302 through the guidance of the threads of the built-in hollow threaded tube 302. The hollow threaded transmission tube 303 drives the multi-purpose bottle assembly 6 to collect the land below, and at the same time drives the cutting tool 406 to cut the land below.

[0040] like Figure 2-Figure 10As shown, a multi-purpose bottle assembly 6 is installed inside the soil stratification assembly 3 through a magnetic suction assembly. The multi-purpose bottle assembly 6 can be a collection bottle for collecting land samples at each specified range level or a medicine bottle for repairing according to the soil layer conditions. It is explained here that an auxiliary transportation assembly for transporting the multi-purpose bottle assembly 6 can be installed through a slot on the inner wall of the hollow threaded transmission tube 303, which transports the multi-purpose bottle assembly 6 to the bottom of the hollow threaded transmission tube 303. The multi-purpose bottle assembly 6 is positioned by a magnetic suction buckle installed at the bottom of the hollow threaded transmission tube 303 to collect the soil below, or a hook is installed on the top of the multi-purpose bottle assembly 6. The staff uses the hook to slide the multi-purpose bottle assembly 6 down along the slot of the hollow threaded transmission tube 303 to the bottom of the hollow threaded transmission tube 303. A soil layer variable protection assembly 4 for corresponding protection according to the soil collection steps is installed on one side of the soil stratification assembly 3;

[0041] The soil layer variable protection component 4 includes an external protection frame 404 fixedly installed at the bottom of the soil stratification component 3, a plurality of tool placement blocks 405 arranged in an annular state about the surface of the external protection frame 404 are fixedly installed at the bottom of the external protection frame 404, the inner wall of the tool placement block 405 is threadedly connected with the same number of cutting tools 406, a multi-sliding hole block 401 is fixedly installed on the inner ring wall of the external protection frame 404, and the multi-sliding hole block 401 is rotatably connected to a multi-sliding hole gear 403 on one side away from the tool placement block 405, the interior of the external protection frame 404 is rotatably connected with an auxiliary gear through a first motor, and the auxiliary gear is arranged in a meshing state with the multi-sliding hole gear 403, the interior of the multi-sliding hole gear 403 is slidably connected with a multi-purpose slide plate 402 with the same number of cutting tools 406 through a plurality of arc tracks, the multi-purpose slide plate 402 passes through the multi-sliding hole gear 403 and is fixedly connected to one side of the multi-sliding hole block 401, and the surface of the multi-purpose slide plate 402 is threaded, which can cooperate with the cutting tool 406 to mine the land below;

[0042] The soil stratification component 3 drives the external protection frame 404 to move downward along the land, and as the hollow threaded transmission tube 303 drives multiple tool placement blocks 405 and cutting tools 406 to rotate through the external protection frame 404, the land below is rotated to cut off the plant roots and stems in the wetland and exclude stones, thereby preventing the multi-purpose bottle component 6 from affecting the collection of samples. At this time, the multi-purpose slide plate 402 is attached between every two tool placement blocks 405 to form an external frame, which is attached to the side wall of the land at the cutting position at this time, and supports the land to prevent the side wall from collapsing when the cutting tool 406 rotates, causing the upper and lower layers of land to mix. At the same time, the tool placement block 405 first collects the first layer of land, and the first motor fixedly installed in the external protection frame 404 drives the auxiliary gear to rotate, and the auxiliary gear is meshed with the multi-sliding hole gear 403 to bring The multi-slide hole gear 403 rotates, and a relative motion state is formed between the multi-slide hole gear 403, the multi-slide hole gear 403 and the external protective frame 404. The multi-purpose slide plate 402 slides toward the position of the multi-purpose bottle assembly 6 along the slide holes of the multi-slide hole block 401 and the external protective frame 404 and the arc track of the multi-slide hole gear 403. In this process, the multi-purpose slide plate 402 gathers the cut plants and the samples of this layer toward the middle, which is convenient for the multi-purpose bottle assembly 6 to collect the plant rhizomes and soil samples. The samples can be fully collected, and the staff can analyze the growth conditions of the plant rhizomes and the wetland samples. At the same time, as multiple multi-purpose slide plates 402 gather together to form a sealing frame, when the multi-purpose bottle assembly 6 absorbs the sample through the air pump, the upper layer of the soil is prevented from sinking due to suction, which affects the accuracy of the land sample collection;

[0043] Then, samples are collected from the land below according to the hierarchical divisions.

[0044] In this embodiment, Figure 3-7As shown, an airbag buffer component 5 is installed on one side of the soil layer change protection component 4, and the airbag buffer component 5 includes a hollow support rod 504, and a two-way sliding cavity block 501 is fixedly installed on the upper and lower sides of the hollow support rod 504. The two-way sliding cavity block 501 is fixedly installed on one side of the multi-purpose slide plate 402, and a sliding hole consistent with the sliding rail opened by the multi-sliding hole block 401 is opened on the surface of the external protection frame 404, and an airbag telescopic pad 507 is fixedly connected to the outer side of the two-way sliding cavity block 501, and the airbag telescopic pad 507 is away from the two-way slide. One side of the cavity block 501 is connected to a fixed ring block 701, which is fixedly mounted on the inner wall of the hollow threaded transmission tube 303, and the airbag telescopic pad 507 is fitted directly below the sliding hole of the external protection frame 404. The interior of the hollow support rod 504 is slidably connected to a pressing short rod 503, and the interior of the hollow support rod 504 is fixedly connected to a cushion block 505. A spring 506 is fixedly connected between the pressing short rod 503 and the cushion block 505. Two foldable airbags 507 are connected on both sides of the hollow support rod 504. 02, and the two foldable air bags 502 are attached to the upper surface of the external protection frame 404, and the multi-purpose slide plate 402 drives the two-way sliding cavity block 501 and the pressing short rod 503 to slide along the sliding hole on the external protection frame 404, and protects the cutting position of the same-layer cutting tool 406. When the land above the soil layer change protection component 4 collapses slightly, the collapsed land has priority to contact the pressing short rod 503, and the pressing short rod 503 is pressed on the limit descending hollow support of the cushion block 505 and the spring 506. The airflow inside the support rod 504 flows into the foldable airbag 502, and the foldable airbag 502 is compressed to open outward, providing corresponding support for the land above, preventing the upper layer of wetland soil from falling down to the lower layer and mixing, thereby improving the stability of the multi-purpose bottle assembly 6 when collecting samples. At the same time, when the two-way sliding cavity block 501 slides outward, the airbag telescopic pad 507 is in a telescopic state between the fixed ring block 701 and the two-way sliding cavity block 501, always blocking the sliding hole below, preventing the upper soil from mixing into the lower area.

[0045] like Figure 10-12As shown, a bottle body positioning assembly 7 is installed inside the soil layer variable protection assembly 4, and the bottle body positioning assembly 7 includes a corresponding positioning ring 705. A hollow sliding cavity block 407 is fixedly installed on one side of the multi-sliding hole gear 403. The interior of the hollow sliding cavity block 407 is fixedly connected with a corresponding positioning ring 705 through an arc-shaped installation cavity 408. The corresponding positioning ring 705 is rotatably installed on the inner wall of the fixed ring block 701. The surface of the fixed ring block 701 is fixedly connected to the limited slot block 704 through an arc-shaped path 703. Three positioning hinged rods 702 are hinged on the top of the corresponding positioning ring 705. One side of the positioning hinged rod 702 is located inside the limited slot block 704. When multiple multi-purpose sliding holes are engaged, the corresponding positioning ring 705 is rotated on the inner wall of the fixed ring block 701. The surface of the fixed ring block 701 is fixedly connected to the limited slot block 704 through an arc-shaped path 703. When the plate 402 gathers toward the middle, the corresponding positioning ring 705 rotates along with the hollow sliding cavity block 407 through the arc-shaped installation cavity 408, and the corresponding positioning ring 705 drives the positioning hinge rod 702 to rotate. During the rotation process, the positioning hinge rod 702 is limited by the limiting slot block 704 in the arc-shaped path 703 and rotates along the connection with the corresponding positioning ring 705. At this time, the positioning hinge rod 702 rotates toward the center of the multi-purpose bottle assembly 6, and multiple positioning hinge rods 702 fully clamp the multi-purpose bottle assembly 6, so that when the multi-purpose bottle assembly 6 collects samples within the wrapping range of the multi-purpose slide plate 402, the bottle body is fully positioned and more stable, and is not easy to shake during collection.
