Accurate sample separation device for water body sediment sample

Abstract

The invention discloses an accurate water body sediment sample separation device which comprises a sample separation fixing device used for fixing a columnar sediment sample; a sample separating and moving device used for cutting the columnar sediment sample into a plurality of small sections along the length direction and sequentially feeding the small sections of samples into a gas blowing device; the gas blowing device used for blowing the small sections of samples from the sample separating and moving device into the sample bag; a sample bag supply device used for opening the sample bag below the gas blowing device, sealing the sample bag after the small sections of samples fall into the sample bag, and then loosening the sample bag to enable the sample bag to fall into a sample transfer device; and a sample conveying and recycling device which is used for transferring and storing the sample bag which fall on the sample conveying and recycling device and are filled with the small sections of samples. According to the invention, the sample separation efficiency can be greatly improved, the cost is reduced, manual sample separation errors and sample loss are reduced, the stratification of the sample is protected, and the accuracy of an experimental result is improved.

Description

Technical field [0001] The present invention relates to the field of pre-sediment sample, and more particularly to a precision sampling device for a water deposit sample. Background technique [0002] With the continuous progress of the Ocean Plan and Shenzhen Sea Drilling Plan, researchers have become more and more detained by the exploration of the water world. At the same time, precious sediment samples from water from the ocean, lake are also increasingly rich. Different marine science test boats and research teams have accumulated some methods for acquiring water deposits, such as TV grip, TV multi-tube sampling, gravity column sampling, box sample, compressive sampling, etc. Through continuous accumulation, researchers have obtained some skilled tips and methods of water sediment sultime. Depending on the sampling conditions and equipment, the water deposits generally sampling the length of several tens of centimeters to 100 meters. Depending on the purpose of the research,...
