Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil sampling device for sampling and monitoring heavy metal components in soil profiles. Background Art

[0002] Heavy metal pollution in soil mainly comes from industrial and agricultural activities, such as smelting, chemical industry, pesticide use, etc. Bismuth, strontium, and thallium in soil may all pose hazards to the environment and human health. Soil heavy metal sampling can help monitor and prevent environmental pollution by detecting the heavy metal content in soil. Among them, soil profile samples are for studying the basic physical and chemical properties and occurrence classification of soil. According to the soil type, a representative site is selected to excavate a profile, and soil samples are collected from bottom to top according to the soil occurrence layer. Select the farmland to be detected, find a typical profile, use a spade to dig soil samples at different depths. The sampling depth is fixed each time. Put the soil samples at each depth into a plastic bag, seal it tightly, and mark the sampling depth with a scale. Mark the sampling location and date on the plastic bag for subsequent laboratory analysis.

[0003] In the prior art, the process of profile sampling is different from traditional ground sampling. Traditional sampling is carried out from top to bottom for deep sampling, while profile sampling needs to be carried out horizontally and deeply from the excavated soil profile. And the sampled soil is mostly rectangular. The existing profile sampler is a rectangular shovel-shaped container with a sharp cutting edge at the bottom, which is convenient for penetrating into the soil and is equipped with a handle. It needs to be manually pushed into the soil. The force required for direct pushing is relatively large, and without calibration, it is easy to enter obliquely, and it is easy to scatter soil when pulling out the sampler subsequently. Therefore, we propose a soil sampling device for sampling and monitoring heavy metal components in soil profiles to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a soil sampling device for sampling and monitoring heavy metal components in soil profiles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A soil sampling device for monitoring heavy metal components in soil profiles, comprising a circular fitting plate. A rectangular groove is provided on the outer wall of the circular fitting plate. A rectangular pipe is fixedly connected to the outer wall of the circular fitting plate. A sampling shovel is slidably connected inside the rectangular pipe. A connecting block is fixedly connected inside the sampling shovel. A connecting sleeve is fixedly connected to the outer wall of the rectangular pipe. A threaded rod is threadedly connected to the inner wall of the connecting sleeve. One end of the threaded rod is rotatably connected to a rectangular rod. A groove is provided at one end of the rectangular rod. A connecting rod is rotatably connected to the inner wall of the groove. A long groove is provided on the outer wall of the connecting rod. A telescopic rod is slidably connected to the inner wall of the long groove. A pushing mechanism is provided on the outer wall of the connecting block.

[0007] Preferably, the pushing mechanism includes a U-shaped member. A pushing rod is fixedly connected to the outer wall of the connecting block. One end of the pushing rod is fixedly connected to the outer wall of the U-shaped member. An I-shaped pulley is rotatably connected to the inner wall of the U-shaped member. By setting the I-shaped pulley, after being squeezed to the left by the connecting rod, it moves in an arc-shaped trajectory, and the I-shaped pulley reduces the friction with the connecting rod by rotating.

[0008] Preferably, a threaded hole is provided on the outer wall of the connecting rod. A bolt is threadedly connected to the inner wall of the threaded hole. One end of the bolt is pressed against the outer wall of the telescopic rod. By setting the bolt, the telescopic rod is fixed in the long groove of the connecting rod.

[0009] Preferably, one end of the telescopic rod is fixedly connected to a first grip. The first grip is held by hand to apply force to drive the connecting rod to rotate.

[0010] Preferably, the outer wall of the I-shaped pulley is in contact with the outer wall of the connecting rod.

[0011] Preferably, a second grip is fixedly connected to the outer wall of the rectangular pipe.

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] In this solution, by setting the circular fitting plate, rectangular groove, rectangular pipe, sampling shovel, connecting block, pushing rod, U-shaped member and I-shaped pulley, the circular fitting plate increases the support area and cooperates with the rectangular pipe to assist the sampling shovel to move linearly, avoiding the sampling shovel from tilting and penetrating into the soil profile. The I-shaped pulley reduces the friction with the connecting rod;

[0014] By setting the connecting sleeve, threaded rod, rectangular rod, connecting rod, telescopic rod, bolt, first grip and second grip, the positions of the rectangular rod and the connecting rod can be adjusted, which is convenient for pressing the sampling shovel into the soil profile. At the same time, by using the lever principle, a relatively small force can generate a relatively large force, which is more labor-saving compared with directly pushing the sampling shovel.
