Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, and more specifically to a sampling device for soil heavy metal analysis. Background Art

[0002] Soil is a natural body formed by the interaction of parent material, climate, biology, topography and time. In different natural environments, the formation process and properties of soil are unique. Soil is a component of the biosphere on the earth's surface. It provides nutrients and water for terrestrial plants and is an important place for plants to carry out photosynthesis and energy exchange. When analyzing heavy metals in soil, a sampling device is needed to take samples.

By starting the motor, the stud is rotated, and the screw groove inside the lifting block is matched with the screw thread. When the stud is rotated, the lifting block will move on the outside thereof, and it can be lifted and lowered by rotating in different directions, thereby driving the rotating drum and the sampling drum to be lifted and lowered, so that they can be inserted into the soil. The rotation of the stud will drive the rotating block to rotate, and the rotation can be lifted and lowered inside the rotating drum. The rotation of the rotating block can drive the rotating drum to rotate on the outside of the lifting block, thereby allowing the sampling drum to rotate, thereby allowing it to drill into the soil more easily. The soil can be squeezed into the inside thereof by continuous drilling, and the drilling depth can be known by observing the scale corresponding to the supporting plate when the lifting block is lifted and lowered, thereby ensuring that the soil at different depths can be sampled. After the sampling is completed, it is rotated in the opposite direction so that it can be taken out. The sampling drum can be taken out by unscrewing the bolt, which is convenient for taking out the soil inside it and convenient for subsequent detection and analysis.
