Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a deep soil sampling device for ecological restoration. Background Art

[0002] Ecological restoration refers to geological actions or phenomena formed under the influence of natural or human factors, which cause losses to human life and property and damage to the environment. The distribution and variation patterns of ecological restoration in time and space are both subject to the natural environment and related to human activities. It is often the result of the interaction between humans and nature. Among them, soil erosion and soil salinization, as a type of ecological restoration, are caused by natural or human factors, leading to a decline in geological quality and having a great impact on human life. Therefore, sampling and management of ecological restoration are particularly critical.

[0003] The existing patent (publication number: CN117740448B) discloses a deep sampling device for soil survey for ecological restoration, including a sampling support, a universal wheel is arranged at the bottom of the sampling support, a connecting sleeve is arranged on the sampling support, an adjusting screw is threadedly connected to the connecting sleeve, an operating handle is installed on the top of the adjusting screw, and a ground plug is installed at the bottom of the adjusting screw. A deep sampling mechanism is also arranged on the sampling support, and the deep sampling mechanism is used for sampling. The deep sampling device is moved to the sampling position by the universal wheel, so that the deep sampling device is easy to move. The adjusting screw is driven to rotate by the operating handle, so that the adjusting screw rotates and moves downward in the connecting sleeve. The downward movement of the adjusting screw can drive the ground plug to move downward, so that the ground plug is inserted into the geological soil, which is convenient for fixing the deep sampling device, making the deep sampling device stable and not easy to slide relatively, and can fully ensure the smooth progress of the deep sampling work of the geological soil.

[0004] However, the above technical solution still has certain defects. When sampling, the above technical solution drills vertically downward into the ground to sample the underground soil. However, after sampling, the samples obtained by this sampling method are relatively limited and not uniform. What technicians in this technical field can think of is to add a horizontal sampling sampling head to the side wall of the drill rod to perform horizontal sampling. However, the sampling range of this technical means is small, and the horizontal sampling head extends outward for a short distance. After the sampling is completed, the horizontal sampling head will hinder the lifting of the drill rod from the underground, and the soil sample inside the horizontal sampling head is not sufficiently sealed and is easy to mix. For this reason, a deep soil sampling device for ecological restoration is proposed. Summary of the invention

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure.

[0021] A deep soil sampling device for ecological restoration, such as Figures 1 to 10 As shown, the drilling mechanism 1 includes a base 101, the inner wall of the base 101 is fixedly connected with multiple groups of guide wheels 107, a drill tube 104 is abutted between the multiple groups of guide wheels 107, a drill bit 105 is fixedly connected to the bottom end of the drill tube 104, and multiple groups of high-hardness alloy grinding heads 106 are fixedly connected to the outer wall of the drill bit 105; The inner wall of the drill tube 104 is fixedly connected with multiple groups of guide tubes 201, and the multiple groups of guide tubes 201 are connected to the outside of the drill tube 104. The inner wall of the guide tube 201 is slidably sleeved with a sampling head 202 near the bottom, and the inner wall of the guide tube 201 is slidably sleeved with a pushing block 203 near the top. Multiple groups of sample storage tubes 204 are rotatably connected between the sampling head 202 and the pushing block 203. The top and bottom ends of the multiple groups of sample storage tubes 204 are rotatably connected to the ends of another group of sample storage tubes 204, and the multiple groups of sample storage tubes 204 can be flipped unidirectionally. The inner wall sliding sleeve of the drill tube 104 is provided with a connecting ring 205, and the connecting ring 205 is fixedly connected Connected to the outer wall of multiple groups of pushing blocks 203, the bottom end of the connecting ring 205 is fixedly connected to multiple groups of multi-stage hydraulic rods 207, the bottom ends of the multiple groups of multi-stage hydraulic rods 207 are fixedly connected to the inner wall of the drill barrel 104, the top of the base 101 is fixedly connected to two groups of guide rods 102, the outer wall sliding sleeves of the two groups of guide rods 102 are provided with an upper connecting plate 103, the upper connecting plate 103 is rotatably connected to the top of the drill barrel 104, the top of the upper connecting plate 103 is fixedly connected to two groups of hydraulic motors 108, the bottom end of the upper connecting plate 103 is provided with a gear set 109, the gear set 109 is connected to the two groups of hydraulic motors 108 and the drill barrel 104.

[0022] The gear set 109 is driven by the hydraulic motor 108 to drive the drill barrel 104 to rotate. During the rotation of the drill barrel 104, the drill bit 105 is driven to rotate. During the rotation of the drill bit 105, the high-strength alloy grinding head is driven to rotate, so that the soil on the ground is broken. In the above process, the handle of the side wall of the upper connecting plate 103 is held and pressed downward, so that the drill barrel 104 drills downward into the soil. During the downward movement of the drill barrel 104, multiple groups of guide wheels 107 provide support force for the drill barrel 104, so that the drill barrel 104 can drill downward into the ground more smoothly. After the drill barrel 104 has drilled into the ground to a sufficient depth, the connecting ring 205 is driven downward by the multi-stage hydraulic rod 207 to slide downward, so that the connecting ring 205 drives the push head downward to slide downward inside the guide tube 201, so that the push head pushes the sample storage tube 204 downward in the guide tube 20 1 slides downward, so that the sample tube 204 pushes the sampling barrel 2021 downward to slide out of the guide tube 201, so that the sampling barrel 2021 is horizontally sampled underground. After the sampling is completed, the multi-stage hydraulic rod 207 drives the connecting ring 205 to reset, so that the connecting ring 205 drives the pushing block 203 to reset, and the pushing block 203 pulls the multiple groups of sample tubes 204 and the sampling head 202 to reset. In the above process, due to the special structure of the sample tube 204, the sample tube 204 and the adjacent sample tube 204 can be flipped in one direction to a certain extent, so that the sample tube 204 can slide out of the guide tube 201 smoothly. Similarly, the sampling head 202 can also slide smoothly inside the guide tube 201, so that the sampling head 202 slides into the guide tube 201, and then lifts up the upper connecting plate 103 to make the drill pipe 104 leave the ground.

[0023] Please refer to Figure 6 , Figure 7 and Figure 8 The sampling head 202 includes a sampling head 202, which is rotatably connected to the bottom end of a group of sampling barrels 2021 at the bottom. A cutter head 2022 is rotatably connected to the inner wall of the sampling head 202 near the bottom end. Two sets of blades 2023 are fixedly connected to the bottom end of the cutter head 2022. The cutter head 2022 has an opening at the connection with the blades 2023. A reduction motor 2024 is fixedly connected to the inner wall of the sampling head 202. The output end of the reduction motor 2024 is fixedly connected to the side wall of the cutter head 2022. The inner wall of the sample storage tube 204 is provided with multiple groups of sealing components 206, and the sealing components 206 include two groups of elastic strips 2061, and the two groups of elastic strips 2061 are fixedly connected between two adjacent groups of sampling tubes, one side of the two groups of elastic strips 2061 is fixedly connected with multiple groups of first support rings 2062, and the other side of the two groups of elastic strips 2061 is fixedly connected with multiple groups of second support rings 2063, and the side walls of the multiple groups of first support rings 2062 and the multiple groups of second support rings 2063 are respectively fixedly connected with multiple groups of films 2064.

[0024] After the sampling head 202 extends out of the guide tube 201, the reduction motor 2024 drives the cutter head 2022 to rotate, and the cutter head 2022 drives the blade 2023 to rotate, so that the blade 2023 cuts the soil, and the sampling barrel 2021 continues to move forward in the soil, so that the soil is introduced into the sampling barrel 2021 from the opening. The reduction motor 2024 ensures that the cutter head 2022 has enough power during the sampling process. In the process of the sample storage tube 204 sliding out or sliding into the guide tube 201, the adjacent sample storage tubes 204 flip over, so that the elastic strip 2061 bends. In the process of the elastic strip 2061 bending, the first support rod 305 is brought closer to each other, and the second support ring 2063 is moved away from each other, so that the film 2064 on the side wall of the first support ring 2062 is folded, and the film 2064 on the side wall of the second support ring 2063 is unfolded, so that the two adjacent groups of sample storage tubes 204 can always remain airtight, so that the soil sample can always be completely preserved after the sampling is completed.

[0025] Please refer to Figure 4 , Figure 8 and Fig.10 The inner wall of the multiple groups of sampling heads 202 is sleeved with an extraction mechanism 3, and the extraction mechanism 3 includes multiple groups of connecting heads 301, and the multiple groups of connecting heads 301 are respectively sleeved inside a group of sampling heads 202. The ends of each group of sampling heads 202 are fixedly connected with multiple groups of primary steel wire ropes 302, and the ends of the multiple groups of primary steel wire ropes 302 are fixedly connected with secondary steel wire ropes 303. The ends of the multiple groups of secondary steel wire ropes 303 extend to the outside of the horizontal sampling mechanism 2, and the ends of the multiple groups of secondary steel wire ropes 303 are fixedly connected with upper pull rings 304. The upper pull rings 304 are slidably connected to the inner wall of the drill tube 104 near the top position. The side walls of the connecting heads 301 are hinged with multiple groups of support rods 305, and multiple groups of push membranes 306 are fixedly connected between the multiple groups of support rods 305. Each group of push membranes 306 is respectively fixedly connected between two adjacent groups of support rods 305.

[0026] After the soil sample enters the sampling barrel 221, as more soil continues to enter the sampling barrel 221, the soil sample enters the sample storage tube 204, and the support rod 305 is pushed by the soil and flipped to Figure 9The soil sample can be smoothly put into the sample storage tube 204. After the sampling is completed, the upper pull ring 304 is pulled upward, so that the upper pull ring 304 drives multiple groups of secondary steel wire ropes 303, and the secondary steel wire ropes 303 drive multiple groups of primary steel wire ropes 302, so that the connector 301 is pulled upward. At this time, the support rod 305 is blocked by the soil sample, so that the support rod 305 is turned over to push the membrane 306 to unfold. As the upper pull ring 304 continues to be pulled, the support rod 305 drives the push membrane 306, thereby pushing the soil sample in the sample storage tube 204 to slide upward in the sample storage tube 204. The push film 306 is flipped over to unfold the support rod 305, and the end of the support rod 305 is attached to the inner wall of the sampling barrel 2021. The end of the support rod 305 is arranged in an arc shape, so that in the process of pushing the sample, when the end of the support rod 305 slides over the inner walls of the sampling barrel 2021, the sample tube 204, the first support ring 2062 and the second support ring 2063, the support rod 305 can slide more smoothly without being stuck.

[0027] When in use, the drill barrel 104 and the drill bit 105 drill downward into the ground, and then the connecting ring 205 is pushed by the multi-stage hydraulic rod 207, so that multiple groups of sample tubes 204 and sampling barrels 2021 can be sampled horizontally underground, and the multiple groups of sampling barrels 2021 have different orientations, so that the sampling range is wider, and after the sample is stored in the sample tube 204, the connecting ring 205 is reset to allow the sample tube 204 to slide back into the guide tube 201, so that the drill barrel 104 can be smoothly lifted from the ground, and the samples obtained are richer, making the detection data more accurate and avoiding the limitation of samples on the realization of data. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0028] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
