Abstract

The invention provides a riverbed sediment monitoring sampler, which is mounted in a sampling vehicle body, and comprises a spiral sampling rod for drilling a sediment layer, a mud scraping assembly matched with the spiral sampling rod for use, and a driving assembly for driving the spiral sampling rod to rotationally drill into the sediment layer or spirally withdraw out of the sediment layer; and the mud scraping assembly comprises a bearing plate mounted in the sampling vehicle body and an elastic mud scraping plate fixed on the bearing plate, the free end of the elastic mud scraping plate extends into a spiral groove in the spiral sampling rod, and a plurality of clamping grooves for embedding silt are formed in the spiral groove at intervals. The problems that according to an existing sediment sampler, sediment is inconvenient to unload, and the unloading time is long are solved, the purpose that the sticky sediment in the spiral inter-groove is easily scraped off and falls onto the material receiving plate is achieved, and the sediment sampling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sediment monitoring, in particular to a riverbed sediment monitoring sampler. Background technique [0002] Riverbed sediment monitoring is an important data support for the water conservancy department to study the evolution of ecological environment such as soil erosion and pollutant accumulation in my country's mountain topography. In order to obtain data, it is necessary to carry out sediment sampling in the riverbed of mountains and rivers. During the dry season, when the riverbed is exposed, researchers use fixed-point sampling and testing of the sediment in the riverbed to study the material content in the sediment, so as to provide further information. Water conservancy prevention and control work brings necessary technical support. [0003] At present, in the process of sediment sampling, technicians use traditional samplers for sampling. The samplers use spiral sampling rods to drill to a certa...
