Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a soil heavy metal pollution sampling device. Background Technology

[0002] Soil sampling refers to the methods of collecting soil samples, including the layout and sampling techniques. The selection of sampling points should be based on an understanding of the pollution source, pollution mode, pollution history and current status, and should take into account the soil type, parent material, topography, natural vegetation or crops, etc. When collecting surface soil samples from farmland or wasteland, a small shovel can be used.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: When conducting soil heavy metal pollution investigations, soil samples need to be taken and then sent to the laboratory for analysis. Since the drilling and sampling parts of most samplers are directly intercepted, and the head of the drilling part will wear down after long-term use, the problem of the drill bit being damaged and the entire sampler becoming unusable is easily caused. Therefore, a soil heavy metal pollution sampling device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A soil heavy metal pollution sampling device of this utility model includes a drill rod and a sampling device. A connecting rod is fixedly connected to the upper surface of the drill rod, and a handle is fixedly connected to the upper surface of the connecting rod. The sampling device is disposed on the surface of the drill rod and includes a drill cylinder. The drill cylinder is inserted into the inner surface of the drill rod, and four support columns are fixedly connected to the upper surface of the drill cylinder. The four support columns are inserted into the inner wall of the drill rod, and nuts are threaded onto the surface of the support columns. Multiple drill teeth are fixedly connected to the bottom end of the drill cylinder. When the drill rod is rotated, the drill rod drives the drill cylinder to rotate, and the drill cylinder drives the drill teeth to rotate. The drill teeth break through the soil. By setting up the drill cylinder, support columns, nuts, and drill teeth, it is convenient to drill into the soil, thereby facilitating soil sampling.

[0006] Preferably, the surface of the drill barrel is provided with threaded grooves, the soil moves in the threaded grooves, and the drill barrel discharges excess soil through the threaded grooves.

[0007] Preferably, four locking blocks are fixedly connected to the upper surface of the drill barrel. The locking blocks are inserted into the inner wall of the drill rod. The locking blocks can reduce the force borne by the support column.

[0008] Preferably, a push rod is slidably connected to the inner wall of the drill rod, and a top head is fixedly connected to the bottom end of the push rod. The top head pushes out the soil, and the soil inside the drill rod can be easily removed by setting the push rod and the top head.

[0009] Preferably, two push blocks are fixedly connected to the surface of the push rod, and the surfaces of the two push blocks are slidably connected to the inner wall of the connecting rod. The push blocks drive the push rod to slide, and the push rod can be moved easily by setting the push blocks.

[0010] Preferably, the surface of the connecting rod is provided with multiple storage devices, each including an elastic clip. The sidewall of the elastic clip is fixedly connected to the surface of the connecting rod. A storage cylinder is inserted into the inner surface of the elastic clip. Two limiting blocks are fixedly connected to the surface of the storage cylinder. The two limiting blocks are inserted into the inner surface of the elastic clip. A cap is threaded onto the surface of the storage cylinder. The storage cylinder fits against the elastic clip, and then the elastic clip is released. The elastic clip is sleeved on the surface of the storage cylinder, and the limiting blocks are inserted into the elastic clip. By setting the elastic clip, storage cylinder, and limiting blocks, soil samples can be conveniently stored.

[0011] Preferably, a storage part is fixedly connected to the surface of the storage tube, and information paper is provided on the inner wall of the storage part. The storage part can conveniently fix the information paper and also facilitate the disclosure of information about the soil inside the storage tube.

[0012] The advantages of this utility model are:

[0013] 1. When soil sampling is required, the drill barrel is pushed to insert into the inner wall of the drill rod. As the drill barrel moves, it also drives the support column and the locking block to insert into the drill rod. Then, the nut is rotated to the surface of the support column. When sampling, the handle is pushed to rotate the connecting rod and the drill rod. The rotating rod drives the drill barrel to rotate, and the drill barrel drives the drill teeth to rotate on the soil surface. Some soil will enter the drill barrel, while the excess soil will be discharged through the threaded groove and enter the drill rod. When the soil needs to be removed after sampling, the push block is pushed to slide the push rod. The push block slides on the inner wall of the connecting rod. When the push rod moves, it drives the top head to move, and the top head pushes out the soil in the drill rod. By setting up the whole device, soil sampling can be convenient, and the drill barrel can be easily replaced. The push rod, top head, and push block can easily remove the soil in the drill rod.

[0014] 2. When removing soil samples from the drill rod, this utility model aligns the soil sample with the storage tube, allowing the soil sample to enter the storage tube. Then, the cap is rotated to the surface of the storage tube, and the elastic clip is pried open to fit the storage tube against the elastic clip. The elastic clip is then released to allow it to fit over the surface of the storage tube, while the limiting block is inserted into the elastic clip. The soil sample information is then written on the information paper and inserted into the inner surface of the storage section. By setting up the entire device, it is possible to conveniently collect and store soil samples, and also to conveniently disclose soil sample information. Attached Figure Description
