Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to a portable soil sampling device for land and space planning. Background Technology

[0002] Soil sampling refers to the process of selecting representative sampling points in a target area and collecting soil samples of a certain depth and quantity using specialized tools, in accordance with specific scientific methods and standards. Its core purpose is to provide basic samples for subsequent soil analysis, thereby providing accurate basic soil data support for soil resource surveys, arable land quality assessments, environmental protection monitoring, agricultural fertilization guidance, and the formulation of ecological restoration plans.

[0003] When using a sampling shovel for soil sampling, operators usually hold and manipulate the shovel handle to make the shovel reciprocate vertically, using the tool's own weight and impact inertia to drill into the soil to obtain samples. In actual operation, after multiple impacts, the cutting edge or shovel body of the sampling shovel will exert a strong physical compression and cutting effect on the soil, causing soil particles to break down and destroying the original natural stratification structure of the soil. As a result, the collected samples cannot truly reflect the physical and chemical properties and structural characteristics of different soil layers. Therefore, a portable soil sampling device for land spatial planning is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problem that the cutting edge or shovel body exerts strong physical compression and cutting action on the soil, causing soil particles to break down and destroying the original natural stratification structure of the soil, resulting in the collected samples failing to accurately reflect the physicochemical properties and structural characteristics of different soil layers. This invention provides a portable soil sampling device for land and space planning.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A portable soil sampling device for land use planning includes:

[0007] The connecting rods are multiple and are arranged in a straight line. One end of each connecting rod has a mounting groove, and the other end of each connecting rod has a mounting block connected to the mounting groove.

[0008] A sampling assembly, located on the outside of the connecting rod, is used to extract soil. The sampling assembly includes a sampling component and a control component. The sampling component is located at the bottom of the connecting rod and is used to store the soil. The control component is located on the outside of the connecting rod and is used to provide power to the sampling component. The sampling component works in conjunction with the control component to sample soil at different depths.

[0009] Furthermore, a connecting block is also provided on the outer side of the connecting rod.

[0010] Furthermore, the sampling component includes a sampling shell, there are multiple sampling shells, and the sampling shells are arc-shaped. One end of the sampling shell is connected to the connecting rod, and the other end of the sampling shell is provided with a connecting groove, and a fixing ring is threaded to the outside of the connecting groove.

[0011] Furthermore, the control component includes a splicing block connected to a connecting rod. A guide rod and a limiting block are sequentially provided on the outer side of the splicing block. A sliding sleeve is slidably connected to the outer side of the guide rod. A baffle is provided on the sliding sleeve relative to the end of the connecting rod. A connecting post is provided on the other end of the sliding sleeve. Blocking blocks are provided on the opposite sides of the baffle and the connecting rod. A counterweight for increasing the weight of the sliding sleeve is also provided on the outer side of the connecting post.

[0012] Furthermore, the counterweight includes multiple counterweight blocks, which slide on the outside of the guide rod. Each counterweight block has a positioning ring at both ends, with one positioning ring located on the outside of the connecting column. Each positioning ring is threaded with a connecting ring on its outer side.

[0028] like Figures 1 to 6As shown, a portable soil sampling device for land use planning includes: multiple connecting rods 1 arranged in a straight line, one end of each connecting rod 1 having an installation groove 103, and the other end having an installation block 102 connected to the installation groove 103; and a sampling assembly disposed on the outside of the connecting rods 1 for extracting soil. The sampling assembly includes a sampling element 2 and a control element 3. The sampling element 2 is disposed at the bottom of the connecting rods 1 for storing the soil, and the control element 3 is disposed on the outside of the connecting rods 1 for providing power to the sampling element 2. The sampling element 2, in conjunction with the control element 3, samples soil at different depths. Specifically, when it is necessary to sample soil at the land use planning site... During sampling, staff can select the number of connecting rods 1 according to the actual sampling depth requirements on site. First, align the mounting block 102 of a single connecting rod 1 with the mounting groove 103 of another connecting rod 1, and quickly assemble it by rotating the thread without the need for complicated tools. After assembly, fix the sampling component 2 at the end of the bottom connecting rod 1, and install the control component 3 on the outside of the top connecting rod 1. Then, drive the sampling component 2 to drill into the soil for sampling through the control component 3. After sampling, the connecting rod 1 can be disassembled by rotating in the opposite direction. The connecting rod 1, sampling component 2, and control component 3 can be stored in a portable case, which greatly reduces the carrying volume. It is especially suitable for sampling scenarios in the field where there is no direct transportation, reducing the burden of carrying staff.

[0029] like Figures 1 to 6 As shown, a connecting block 101 is also provided on the outside of the connecting rod 1. Specifically, the connecting block 101 and the connecting rod 1 are connected by welding or bolts. If welding is used, the structural stability of the connecting block 101 and the connecting rod 1 can be ensured, and loosening during long-term use can be avoided. If bolts are used, it is convenient to replace the connecting block 101 individually when it is damaged in the future, reducing maintenance costs. When assembling multiple connecting rods 1, the operator can use an adjustable wrench or an open-end wrench to wrench on the outer plane of the connecting block 101. The connecting block 101 is preferably set as a regular hexagonal structure, which is compatible with commonly used wrenches. By rotating the connecting rod 1 with the wrench, the thread engagement between the mounting block 102 and the mounting groove 103 can be easily completed. This is more labor-saving than rotating by hand and can ensure the coaxiality of the connecting rod 1 after assembly, avoiding the deviation of the drilling direction of the sampling part 2 due to the misalignment of the assembly.

[0030] like Figures 1 to 6As shown, the sampling component 2 includes multiple sampling shells 201, each in an arc shape. One end of each sampling shell 201 is connected to the connecting rod 1, and the other end of each sampling shell 201 has a connecting groove 203. A fixing ring 202 is threaded onto the outer side of the connecting groove 203. Specifically, the sampling shells 201 are arc-shaped, with the arc angle of a single sampling shell 201 being 180°, 120°, or 90°, ensuring that the sampling shells 201 can form a complete cylindrical cavity after assembly. The cavity diameter is selected according to the sampling requirements. This cavity can completely accommodate columnar soil samples, avoiding soil stratification damage during sampling. During assembly, the inner sides of each sampling shell 201 are first fitted together, so that the edges of adjacent sampling shells 201 are aligned. Next, align the top of the assembled sampling shell 201 with the connection interface at the bottom of the connecting rod 1, and fix it with threads or buckles. Then, slip the fixing ring 202 onto the bottom of the sampling shell 201, and rotate the fixing ring 202 to engage with the external thread of the connecting groove 203 until the top of the fixing ring 202 is tightly fitted to the bottom of the sampling shell 201. At this point, the top of the sampling shell 201 is limited by the connecting rod 1, and the bottom is fixed by the fixing ring 202, forming a stable sampling cavity. Even when drilling in hard soil, there will be no loosening or misalignment of the sampling shell 201 that could lead to soil sample leakage. After sampling, the sampling shell 201 can be disassembled by rotating the fixing ring 202 in the opposite direction, making it easy to take out the complete columnar soil sample for stratified testing.

[0031] like Figures 1 to 6As shown, the control component 3 includes a splicing block 307, which is connected to the connecting rod 1. A guide rod 302 and a limiting block 305 are sequentially arranged on the outer side of the splicing block 307. A sliding sleeve 301 is slidably connected to the outer side of the guide rod 302. A baffle 303 is provided at the end of the sliding sleeve 301 opposite to the connecting rod 1. A connecting post 306 is provided at the other end of the sliding sleeve 301. Blocking blocks 304 are provided on both the baffle 303 and the side opposite to the connecting rod 1. A counterweight 4 is also provided on the outer side of the connecting post 306 to increase the weight of the sliding sleeve 301. Specifically, the inner wall of the sliding sleeve 301 has an internal thread, and the top of the connecting rod 1 has an external thread. The two are connected by threads. Workers can flexibly adjust the initial position of the sliding sleeve 301 on the connecting rod 1 according to the total length of the connecting rod 1. During field sampling, the sampling shell 201 is first aligned with the target by holding the connecting rod 1. At the sampling point, ensure the sampling shell 201 is perpendicular to the ground. Then, grasp the sliding sleeve 301 with both hands and pull it upwards until the top of the sliding sleeve 301 contacts the limiting block 305. The limiting block 305 is made of rubber, which can reduce the collision noise during lifting. Then, quickly release the sliding sleeve 301, allowing it to fall freely along the guide rod 302. The impact force is transmitted to the connecting rod 1 and the sampling shell 201 through the baffle 303 at the bottom of the sliding sleeve 301 impacting the splicing block 307, driving the sampling shell 201 to drill into the soil. Ensure that the sliding sleeve 301 falls without deviation and that the impact force is accurately transmitted. The diameter of the baffle 303 is larger than that of the sliding sleeve 301, which can effectively prevent the operator's hands from reaching between the sliding sleeve 301 and the splicing block 307. At the same time, the blocking block 304 prevents the sliding sleeve 301 and the splicing block 307 from cracking or deforming due to long-term impact, thus extending the service life of the device.

[0032] like Figures 1 to 6As shown, the counterweight 4 includes multiple counterweight blocks 401, which slide outside the guide rod 302. Each counterweight block 401 has a positioning ring 402 at both ends. One positioning ring 402 is located outside the connecting column 306. Each positioning ring 402 is threadedly connected to a connecting ring 403. Specifically, the connecting column 306 is an inverted conical truncated pyramid with a diameter smaller than its base. The inner wall of the positioning ring 402 has a tapered hole matching the taper of the connecting column 306. When the positioning ring 402 is fitted onto the outside of the connecting column 306, the tapered structure automatically centers itself, preventing the positioning ring 402 from shifting. The counterweight blocks 401 are made of cast iron, and the weight of a single block can be selected according to requirements. Workers can choose the number of counterweight blocks 401 based on soil hardness. During installation, first, place a positioning ring 402 on the bottom of the connecting column 306, then stack the required number of counterweights 401 in sequence, and finally place another positioning ring 402 on the top of the connecting column 306. Align the two connecting rings 403 with the threads on the outside of the positioning rings 402, and rotate the connecting rings 403 clockwise until the connecting rings 403 and counterweights 401 are tightly fitted. At this time, the counterweights 401 are clamped and fixed by the upper and lower positioning rings 402, and rise and fall synchronously with the sliding sleeve 301. This design can flexibly adjust the total weight of the sliding sleeve 301, which can ensure sufficient impact force in hard soil, and avoid excessive drilling of the sampling shell 201 due to excessive impact force in soft soil. At the same time, the counterweights 401 can be disassembled and stored, further improving the portability of the device.

[0033] like Figures 1 to 6 As shown, the counterweight 401 also has a cavity inside, and there are multiple shock absorbers inside the cavity. Specifically, the shock absorbers filling the cavity can be selected in terms of material and shape according to the actual shock absorption requirements. If it is necessary to absorb the impact vibration in the vertical direction, plate-shaped shock absorbers can be selected. When the sliding sleeve 301 is impacted, the plate-shaped shock absorbers can absorb the vibration energy through compression deformation. If it is necessary to absorb vibrations in multiple directions at the same time, spherical shock absorbers can be selected. The rubber ball can roll freely in the cavity and absorb vibrations in different directions through collision and deformation.

[0034] like Figures 1 to 6As shown, the working state of this portable soil sampling device for land and space planning is as follows: During sampling, the number of connecting rods 1 is selected according to the target sampling depth. Assembly is completed by threading the mounting block 102 of one connecting rod 1 to the mounting groove 103 of another connecting rod 1. During this process, the connecting block 101 and a wrench can be used to improve assembly efficiency and coaxiality. Next, the sampling component 2 is assembled by fitting multiple arc-shaped sampling shells 201 together to form a cylindrical cavity. The top of the assembled sampling shell 201 is fixed to the bottom interface of the connecting rod 1 via a positioning boss. Then, the fixing ring 202 is inserted into the bottom connecting groove 203 of the sampling shell 201 and screwed tight to limit the positions of both ends of the sampling shell 201. Subsequently, the control component 3 is installed, and the sliding sleeve 301 is connected to the top external thread of the connecting rod 1 via an inner wall thread. The initial position of the sliding sleeve 301 is adjusted according to the total length of the connecting rod 1. Simultaneously, soil samples are collected on the outside of the connecting column 306 of the control component 3. The number of counterweights 401 is selected based on soil hardness. The counterweights 401 are fixed to the connecting column 306 by the positioning ring 402 and the connecting ring 403, increasing the weight of the sliding sleeve 301. During sampling, the staff holds the connecting rod 1, aligns the sampling shell 201 with the target point, and uses a level to calibrate the verticality. The staff then lifts the sliding sleeve 301 with both hands, raising it along the guide rod 302 until it contacts the limiting block 305. The staff then releases the sliding sleeve 301 to allow it to fall freely. The bottom baffle 303 of the sliding sleeve 301 impacts the splicing block 307. During this process, the blocking block 304 absorbs the impact force through deformation, preventing damage to the components. At the same time, the increased weight of the counterweights 401 increases the impact force, which is transmitted to the sampling shell 201 through the connecting rod 1, allowing the sampling shell 201 to penetrate the soil and complete the sampling. The plate-shaped or spherical shock-absorbing blocks inside the cavity of the counterweights 401 can absorb vibration and reduce noise, ensuring a stable sampling process with minimal interference to the surrounding environment.

[0035] In summary, this utility model includes: a connecting rod 1, wherein there are multiple connecting rods 1 arranged in a straight line, one end of the connecting rod 1 is provided with an installation groove 103, and the other end of the connecting rod 1 is provided with an installation block 102, and the installation block 102 is connected to the installation groove 103; a sampling component, which is set on the outside of the connecting rod 1 for taking out soil, the sampling component includes a sampling element 2 and a control element 3, the sampling element 2 is set at the bottom end of the connecting rod 1 for storing soil, and the control element 3 is set on the outside of the connecting rod 1 for providing power to the sampling element 2, and the sampling element 2 cooperates with the control element 3 to sample soil at different depths; this utility model, through the setting of the control element 3, realizes the cooperation of the sliding sleeve 301, guide rod 302, baffle 303 and splicing block 307, thereby providing downward power to the sampling element 2 during use, avoiding reciprocating impact of the sampling shell 201 during the sampling process, and ensuring the integrity of soil layers during sampling.
