Saw cutting device and method of sampling pipe for soil sampling

Technical Field

The invention relates to the field of soil sampling, in particular to a saw cutting device and a saw cutting method for a sampling pipe for soil sampling.

Background

The soil sampling mode is that external force is utilized to insert the sampling pipe into soil to a certain depth, then soil is left to form a sampling sample section in the sampling pipe, and then according to the requirement of project analysis, the soil with the specified position length in the sampling pipe needs to be taken out for analysis. When the soil is taken out, the sampling pipe needs to be sawed, usually, the sampling pipe is sawed by manually operating an electric saw blade or a manual saw, and then the soil is taken out by using a tool. At present, no fixed-point saw cutting device for a soil sampling pipe exists.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the saw cutting method of the sampling tube for soil sampling, the saw cutting method can fix and saw cut the sampling tube at a fixed point, and the sampling tube is automatically extruded and sampled, so that the manual work is replaced, the manual participation degree is reduced, and the problems in the background art are effectively solved.

In order to achieve the purpose, the invention provides the following technical scheme: a sawing method of a sampling pipe for soil sampling comprises the following steps:

s1, fixing a sampling pipe on a clamp;

s2, moving the cutting mechanism to a sawing position of the sampling pipe according to a cutting point, and cutting by a saw blade from bottom to top;

s3, resetting the saw blade after the saw blade is cut, and moving the cutting mechanism leftwards to enable the receiving cup to be located right below the section of the sampling tube;
