Description

Technical Field

[0001] The utility model belongs to the technical field of geotechnical engineering, and particularly relates to a soil sampling device that is easy to carry. Background Art

[0002] Soil sampling is an important part of soil science and environmental science. It involves the process of collecting soil samples from the surface or a certain depth underground. The purpose of soil sampling is to obtain the physical, chemical and biological properties of the soil for laboratory analysis or field testing. Soil sampling is crucial in fields such as agriculture, environmental monitoring, geological surveys and engineering project construction. Therefore, in geotechnical engineering, it is necessary to use a soil sampling device to drill into the soil to sample the soil.

[0003] In the existing soil sampling device, a person holds the outer shell of the soil sampling device and inserts the sampling soil on the lower side into the soil, and then rotates the handle to make the handle drive the sampling tube on the lower side to rotate, so that the sampling tube drills into the soil. During the drilling process, part of the soil will be sampled into the interior of the sampling tube. Then the person holds the outer shell of the soil sampling device and pulls the sampling tube out of the ground to achieve soil sampling. However, in actual use, since the outer shell of the soil sampling device is relatively long, it is not convenient to store and carry it. This brings certain restrictions to the person's behavior when moving the soil sampling device or placing the soil sampling device in a storage box for movement, and is inconvenient for the person to carry.
