Description

A soil sample sampler for soil testing

Technical Field

The utility model relates to the technical field of soil samplers, in particular to a soil sample sampler for soil detection.

Background

Soil sampler refers to a tool for obtaining a soil sample. Commonly used are earth boring drills, shovels and shovels. The earth drill consists of a drill bit made of hard material (steel or hard plastic) and a handle. The drill bit is usually spiral or cylindrical, the top end of the spiral drill bit is provided with a pair of sharp knife edges which can be rotated to cut into soil, an expanded soil containing cavity is arranged next to the knife edges, and a soil sample to be collected can be guided into the cavity by drilling down into the soil surface along with the rotation of the handle; the diameter of the cylindrical soil drill is slightly different at two ends, and one end connected with the handle is slightly larger than the end contacted with soil, so that the soil which enters the cylinder when the soil drill fetches the soil can not be scattered due to the movement of the soil drill. The handle of the earth auger is marked with scales so as to control the sampling depth. The soil auger can take out the soil sample after the soil surface is lifted out, the soil samples with different depths can be continuously collected in the original sampling hole, but when the soil auger is pulled out from the soil, soil fragments around the sampling hole are prevented from flowing into the soil taking hole. The soil drill sampling has small damage to soil and can be used for layered soil sampling. Shovels are commonly used to dig profile pits for collecting profile samples or whole specimens. The soil sampler in the prior art has low integrity, needs a complex assembly process and is inconvenient to operate.
