Description

Soil sampling device and sampling method thereof

Technical Field

The invention relates to the field of soil sampling devices, in particular to a soil sampling device and a soil sampling method.

Background

Soil sampling is a means to detect regional soil environment, at present when soil sampling, most is direct to insert sampling equipment's sampling head underground, then pulls out the sampling head with external force, collects the residual soil in the sampling head at last and detects, and the sample through this kind of mode has following problem:

1. when the existing sampling equipment samples, a pit matched with or larger than the sampling head is left on the ground, and the problem that local residents or small animals are affected by the left pit exists, for example, the residents cannot see that the pit is stepped to fall down or the small animals fall into the pit and cannot climb out.

2. The soil in the sampling head is independently taken out and then stored in a specified container after sampling, so that the trouble is quite involved;

3. when the soil core (the soil core refers to the soil far away from the soil surface) needs to be sampled, normal sampling is needed first, then the extracted undisturbed soil is segmented to only reserve the soil core, and the soil core cannot be directly extracted according to the needs.

Therefore, the present invention provides a soil sampling device and a sampling method thereof, so as to solve the above-mentioned problems.
