A Soil Profile Sampler

Abstract

The invention relates to a soil profile sampler, which is characterized by comprising a soil sample and a profile sample divider. The soil profile sampler provided by the invention has smart design and simple structure, and is capable of preventing the collected soil sample from being slipped off and capable of sampling in loosened soil in which the sample is difficult to shape; the soil sample is provided with a plurality of sampling box chambers to guarantee that the soil sample is finely laminated, and a plurality of samples can be accepted simultaneously so as to realize in-situ sampling; and a sampling box has a certain volume and weight, and is convenient to determine the volume weight of the soil sample. The soil profile sample is particularly suitable for field use.

Description

technical field [0001] The present invention relates to soil profile samplers. Background technique [0002] 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 acc...

Problems solved by technology

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. Preservation, it is difficult to accurately determine the position of the interlayer change of soil soil quality, and the thickness of the soil layer and other indicators

The mechanical soil sampler needs to be equipped with a power device, which is inconvenient for field work; the length of the integrated half-round drill is long and it is not easy to carry
