Description

A Soil Profile Sampler

technical field

The present invention relates to soil profile samplers.

Background technique

At present, the known columnar soil sampler is divided into an integrated semicircular chisel drill and a soil columnar cylinder sampler from the drill bit. There are manual soil samplers and mechanical soil samplers in terms of power. The manual soil sampler drive unit is the handle. The operation process is to insert the sampling head vertically into the soil, then press the soil into the sampling head by pressing down, turning, etc., and finally extract the soil sampler from the soil and reversely rotate to obtain a soil sample. The disadvantage of the manual soil sampler is that the soil sample is difficult to form and is easy to slip off from the soil sampling head; moreover, the soil sample collected by the manual soil sampler is rough in layering and cumbersome to pack, and the soil sample cannot be accurately layered and sampled well. It is difficult to accurately determine the interlayer change position of soil soil quality and the thickness of soil layer and other indicators. The mechanical soil sampler needs to be equipped with a power device, which is inconvenient for field operations; the length of the integrated half-round drill is long and it is not easy to carry.
