Description
Technical Field
The invention belongs to the technical field of soil sampling, and particularly relates to sampling equipment for soil sampling.
Background
Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the soil sample in the cross section is performed after the cross section observation is completed. Before sampling, the section should be trimmed and cleaned, the most superficial layer of the floating soil is cut off, and then the sample is taken from the central typical part layer by layer from top to bottom according to the layers.
The existing soil sampler required to be used for soil sampling refers to a tool for acquiring a soil sample. Earth drills, shovels and shovels are commonly used. The earth drill consists of a drill head 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.
