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

Embodiment 1

[0019] Such as figure 1 , 2 As shown in and 3, the push-type quantitative layered sampler is composed of a layered sampling device 1 and a sampling tube 2, wherein the layered sampling device 1 includes a handle 5, a fixing screw button 6, a detachable fixing frame 7, a pull rod 8 and a piston 9 , the top of the pull rod 8 is provided with a handle 5, the bottom end is connected with a piston 9, and the detachable fixed frame 7 is relatively movable and installed on the pull rod 8 between the handle 5 and the piston 9; the sampling tube 2 for sampling is set on the pull rod 8 Outside, it is connected with the detachable fixing frame 7, and the fixing screw button 6 is arranged on the pull rod 8 between the handle 5 and the detachable fixing frame 7, and its position is adjustable.

[0020] The top of the sampling tube 2 is provided with a fixed nut 4, and the fixed nut 4 is installed at 2 cm from the top of the sampling columnar tube 2, and there is one on both sides. The sam...

Embodiment 2

[0025] Adopt above-mentioned embodiment to push type quantitative layered sampler and specifically measure as:

[0026] The length of the pull rod 8 is 60cm, the total length of the sediment sample is 50cm, the piston 9 is pushed into the columnar tube 3, the detachable fixing frame 5 is fixed on the fixing nut 4 of the sampling columnar tube 2, and the sediment sample is pushed to the top of the sampling columnar tube, At this moment, the scale of the pull rod stops at 10cm. The experiment needs to divide the sediment sample every 3cm, tighten the fixing screw 6 and fix it at 13cm, press and hold the handle 5 and push it into the sampling columnar tube 2 until the fixing screw 6 reaches the When dismounting the top of the fixing frame 7 and can no longer push it forward, the front piston pushes out the sample by 3 cm, and the sediment sample is cut off along the edge of the sampling columnar tube 2 with a tool, and the thickness of the sediment sample is 3 cm. Sediment sample...

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...
