Problems solved by technology

The soil and sediment sampler in the prior art usually uses a manual or gravity hammer to vertically move the sampling tube to make the sampling tube enter the soil and sediment. The workload of using this soil and sediment sampler is large, and the operation is time-consuming and laborious. Moreover, when the sampling tube encounters a hard foreign matter, it is easy to damage the end of the sampling tube, and the service life of the sampling tube is short.

Abstract

The invention relates to the technical field of extraction devices, in particular to a soil sediment sampler comprising a fixed joint, a sampling tube and a vibration assembly. The sampling tube is installed at one end of the fixed joint. The vibration assembly is installed at the fixed joint and transmits vibration to the sampling tube by the fixed joint, so that the sampling tube moves in the soil sediment. The sampler has advantages of simple operation, low workload and long service life.

Description

Technical field [0001] The invention relates to the technical field of extraction devices, in particular to a soil bottom mud sampler. Background technique [0002] Soil bottom mud is usually a mixture of clay, silt, organic matter, and various minerals. It is formed by depositing on the land surface or the bottom of the water body after a long time of physical, chemical and biological effects and water transmission. When the water area is polluted, part of the pollutants in the water can be stored in the soil sediment through precipitation or particulate matter adsorption, and re-release under appropriate conditions to become a secondary pollution source. This pollution is called soil sediment pollution. Therefore, collecting and analyzing soil sediment in land, lakes, rivers, ponds and other water bodies is an important part of water environmental protection, scientific research, and pollution control. The correct collection and analysis of continuously deposited soil sediment ...
