Pushing-type quantitative stratified sampling apparatus and application method thereof

Abstract

The invention relates to the technical field of marine organism qualitative and quantitative stratifying and global change studying argillaceous sampling quantitative stratifying in marine geology, in particular to a pushing-type quantitative stratified sampling apparatus and an application method thereof. The pushing-type quantitative stratified sampling apparatus is composed of a stratified sampling unit and a sampling tube. The stratified sampling unit comprises a handle, a fixing screw knob, a detachable fixing frame, a pulling rod and a piston. The handle is arranged at the top end of the pulling rod, the piston is connected to the bottom end of the pulling rod, and the detachable fixing frame is installed on the pulling rod between the handle and the piston in a relative moving mode; and the sampling tube for performing sampling is sleeved outside the pulling rod and connected with the detachable fixing frame, and the fixing screw knob is arranged on the pulling rod between the handle and the detachable fixing frame and detachable in position. The pushing-type quantitative stratified sampling apparatus has the advantages that the structure is simple, the manufacture cost is low, materials are saved, energy is not used, the sampling apparatus is not limited by environments, and samples can be stratified accurately.

Description

technical field [0001] The invention relates to the technical field of qualitative and quantitative marine organisms and mud sampling and quantitative layering for the study of global changes in marine geology, in particular to a push-type quantitative layered sampler and a use method thereof. Background technique [0002] At present, there are two types of columnar sediment samplers, one of which is to use a PVC pipe for vertical sampling after the sediment sample is collected by the box-type mud sampler, and the other is to directly insert the columnar mud sampling pipe vertically into the ground or beach collection station A sediment sample is required. [0003] After the PVC pipe is collected in the box mud sampler, it is generally necessary to use a chainsaw or a saw blade to cut and stratify the PVC pipe from the outside, or divide the PVC pipe into two parts for manual stratification. When using a chainsaw or a saw blade to cut layers from the outside of the PVC pipe...

AI Technical Summary

Problems solved by technology

When using a chainsaw or a saw blade to cut layers from the outside of the PVC pipe, the inaccuracy caused by the influence of the external environment and the instability of manual cutting will easily cause large errors in the experimental samples and affect the experimental data; Second, it is easy to interfere with the internal sample, and because of the internal structure of the tube wall, the sample cannot be completely separated from the tube wall

[0004] In the prior art, the application number is 200720200676.0, the push-type columnar soil sampler with the utility model name, and the transparent columnar mud sampler (3 meters). The BLT5-ASC columnar transparent mud sampler consists of a sampling tube, stainless steel or plastic cutting head , piston push rod, rope, extension rod, handle, impact hammer, scraper, wrench, waterproof portable bag, and spare parts for wear and tear. The device needs to be assembled first when sampling. The thickness of the required sample, and because of its small diameter and thick pipe wall, it is not easy to insert the sampling pipe into the mud in the hard mud area, and it needs to be manually driven into the soil with a hammer, which is cumbersome

And most of the accessories are relatively bulky, and it is not easy to carry when going out for sampling
