Problems solved by technology

[0002] At present, in the study of benthic ecology such as oceans and lakes, when using a mud sampler to collect sediment samples, in the process of pulling the piston to collect mud and pushing the piston to stratify the mud samples, mud samples of different depths enter and exit from the mud sampling port successively. The mud sampling tube will cause the mixing of mud samples at different depths, which cannot guarantee the accuracy of mud sample stratification, and interferes with the composition of mud samples and the study of biological communities in mud samples

Abstract

The invention relates to a flexible layered mud sampler. The flexible layered mud sampler comprises a mud sampling tube which mainly comprises a first mud sampling tube, a second mud sampling tube and a third mud sampling tube, wherein the first mud sampling tube is hermetically arranged in the second mud sampling tube, the second mud sampling tube is hermetically arranged in the third mud sampling tube, the first mud sampling tube is provided with a piston, a first mud sampling opening is formed on the end part of the first mud sampling tube, a second mud sampling opening is formed on the end part of the second mud sampling tube, and a third mud sampling opening is formed on the end part of the third mud sampling tube. The mud sampler is simple in structure and can retract together in the carrying process, so that the mud sampler is convenient to carry. Moreover, when the mud sampler is used for sampling mud, the layering accuracy of a mud sample can be ensured, and composition and origin of the mud sample and biocenosis in the mud sample can be effectively researched.

Description

technical field [0001] The invention relates to the technical field of mud mining, in particular to a telescopic layered mud harvester. Background technique [0002] At present, in the study of benthic ecology such as oceans and lakes, when using a mud sampler to collect sediment samples, in the process of pulling the piston to collect mud and pushing the piston to stratify the mud samples, mud samples of different depths enter and exit from the mud sampling port successively. The mud sampling tube will cause the mixing of mud samples at different depths, which cannot guarantee the accuracy of mud sample stratification, and interferes with the composition of mud samples and the study of biological communities in mud samples. Contents of the invention [0003] The object of the present invention is to provide a telescopic layered mud extractor with simple structure, easy portability, convenient operation and effective layering. [0004] Another object of the present invent...
