Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soil testing technology, and in particular relates to a sampling device for soil testing in environmental protection engineering. Background Technology
[0002] Sampling devices for environmental engineering soil testing are specialized tools used to collect soil samples in soil environmental monitoring and pollution investigation. The main purpose of these devices is to ensure that soil samples accurately reflect the true condition of the soil, thereby providing reliable data for environmental protection, pollution assessment and remediation.
[0003] Soil sampling usually requires drilling. During the drilling process, shallow soil may be carried to deeper layers, resulting in unrepresentative soil samples and biased test data. Therefore, we propose a sampling device for soil testing in environmental engineering. Utility Model Content
[0004] The purpose of this invention is to provide a sampling device for soil testing in environmental engineering. By rotating the second threaded rod, the second threaded cylinder moves downward, and then the second threaded cylinder pushes the sampler through the moving rod, thus solving the problem of accurate soil sampling.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a sampling device for soil testing in environmental protection engineering, including a support frame, a sampling mechanism is provided inside the support frame, and a stabilizing mechanism is provided on the outer surface of the support frame;
[0007] The sampling mechanism includes a fixed body, with a motor fixedly connected to the inner wall of the fixed body. A threaded rod is fixedly connected to the output shaft of the motor via a coupling. A threaded cylinder is threadedly connected to the outer surface of the threaded rod, and a connecting ring is fixedly connected to the outer surface of the threaded cylinder. A sliding cylinder is fixedly connected to the outer surface of the connecting ring. A limit rod is slidably connected to the inner wall of the sliding cylinder, and a pressure sensor is slidably connected to the outer surface of the limit rod. A sampling cylinder is fixedly connected to the inner wall of the connecting ring, and an electric drill bit is fixedly connected to the bottom of the sampling cylinder. A threaded rod is rotatably connected to the inner wall of the sampling cylinder, and a threaded cylinder is threadedly connected to the outer surface of the threaded rod. A moving rod is rotatably connected to the inner wall of the threaded cylinder, and a sampler is rotatably connected to the inner wall of the moving rod. By using a sampler that can slide out from the sampling cylinder, precise soil sampling can be achieved, ensuring that the soil sample collection is representative and better reflects the soil characteristics of the entire land, thus avoiding data deviations caused by improper sampling.
[0008] Furthermore, the bottom of the fixing body is fixedly connected to the top of the support frame, the bottom of the threaded rod penetrates through the top of the support frame and extends into its interior, and the outer surface of the threaded rod is rotatably connected to the inner wall of the support frame.
[0009] Furthermore, the outer surface of the limiting rod is fixedly connected to the outer surface of the support frame, the outer surface of the threaded cylinder is slidably connected to the inner wall of the sampling cylinder, and the outer surface of the sampler is slidably connected to the inner wall of the sampling cylinder.
[0010] Furthermore, the stabilizing mechanism includes a fixing sleeve fixedly connected to the outer surface of the support frame. A total of four fixing sleeves are provided, and a support frame is fixedly connected to the side of the fixing sleeve away from the sampling cylinder.
[0011] Furthermore, the outer surface of the support frame is slidably connected to the outer surface of the support frame, and a bolt is threadedly connected to the inner wall of the support frame, with the outer surface of the bolt threadedly connected to the inner wall of the support frame.
[0012] Furthermore, a grounding box is fixedly connected to one side of the support frame that is close to each other. The grounding box has a sliding groove inside. There are several sliding grooves. A slider is slidably connected to the inner wall of the sliding groove. A movable plate is fixedly connected to one side of the slider that is close to each other.
[0013] Furthermore, the outer surface of the movable plate is slidably connected to the inner wall of the grounding box, and a plug plate is fixedly connected to the bottom of the movable plate. Several plug plates are provided, and a connecting block is fixedly connected to the top of the movable plate. By inserting the plug plate into the soil, the device can be stably fixed, which helps to ensure that the sampler reaches the predetermined depth each time it takes a sample, thereby avoiding the problem of inconsistent depth due to improper operation and ensuring the representativeness and accuracy of the sample.
[0014] Furthermore, the outer surface of the connecting block is slidably connected to the inner wall of the grounding box, and the inner wall of the connecting block is threaded with a bolt two, the outer surface of the bolt two being in contact with the outer surface of the grounding box.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model incorporates a sampler. Rotating the threaded rod causes the threaded cylinder to move downwards along it, pushing the moving rod and thus the sampler into the soil. When the threaded rod becomes difficult to turn, the sampler has reached its maximum position. At this point, the threaded rod can be reversed to retract the sampler into the sampling cylinder. The sampler's ability to slide out of the sampling cylinder allows for precise soil sampling, ensuring representative soil samples that better reflect the overall soil characteristics and avoid data deviations caused by improper sampling.
[0017] 2. This utility model incorporates an insert plate. The support frame contacts the ground, and then the moving plate is pressed down. The moving plate causes the slider to slide within the groove, simultaneously moving the insert plate downwards until it is inserted into the soil. When the moving plate becomes difficult to push, bolt two can be tightened within the connecting block to fix its position. The insert plate, which can be inserted into the soil, provides a stable fixation of the device, ensuring that the sampler reaches the predetermined depth each time it is sampled. This avoids inconsistent depths due to improper operation and guarantees the representativeness and accuracy of the samples.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] One specific application of this embodiment is:
[0034] When the operator needs to use the equipment, first place the support frame 302 in contact with the ground, then press down on the moving plate 307. At this time, the moving plate 307 will cause the slider 306 to slide within the groove 305. Simultaneously, the moving plate 307 will also cause the insertion plate 308 to move downwards, allowing the insertion plate 308 to insert into the soil. If the moving plate 307 is difficult to push, the bolt 310 can be tightened inside the connecting block 309. This will fix the position of the moving plate 307, achieving stable fixation of the device and helping to ensure that the sampler achieves the predetermined sampling results each time. To ensure the representativeness and accuracy of the sample, the pressure sensor 208 is slid on the limiting rod 207, adjusting the distance between the pressure sensor 208 and the sliding cylinder 206 to the required drilling depth. The position of the pressure sensor 208 is then fixed, and the motor 202 is started. The motor 202 will rotate the threaded rod 203, causing the threaded cylinder 204 to move downwards along the threaded rod 203. This movement of the threaded cylinder 204 will then drive the connecting ring 2. 05. Simultaneously, the connecting ring 205 will cause the slide cylinder 206 to slide on the limit rod 207. Then, the connecting ring 205 will drive the electric drill bit 210 to move downward through the sampling cylinder 209, causing the electric drill bit 210 to drill downward. When the slide cylinder 206 touches the pressure sensor 208, the motor 202 stops. At this time, the threaded rod 211 can be rotated. Then, the threaded rod 211 will cause the threaded cylinder 212 to move downward along the threaded rod 211. Then, the threaded cylinder 212 will push the moving rod 213. At this time, the moving rod 213 will also push the sampler 214. The sampler 214 is pushed into the soil. When the threaded rod 211 is difficult to turn, it means that the sampler 214 has moved to its maximum extent. At this time, the threaded rod 211 can be reversed to retract the sampler 214 into the sampling cylinder 209. Then, the motor 202 is reversed to lift the sampling cylinder 209. After that, the soil in the sampler 214 can be collected and sampled. This achieves accurate soil sampling, ensures that the soil sample collection is representative, and thus better reflects the soil characteristics of the entire land, avoiding data deviation caused by improper sampling.
