Problems solved by technology

[0002] The collection of soil samples is the foundation of soil scientific research and geological survey, and provides a material basis for the determination of the physical and chemical properties of soil samples. There are many methods for soil sampling. In the prior art, drill pipe sampling is generally used. When the drill pipe is drilled into the ground Finally, the soil formed a soil column in the drill pipe, and the entire soil column was taken out for analysis. The above-mentioned sampling drill pipe cannot distinguish samples with different sampling layers and depths.

Abstract

The invention relates to the technical field of soil sampling and particularly relates to a soil sampling device comprising a sampling drum and a pushing and pulling component. The soil sampling device comprises a sampling drum and a pushing and pulling component, wherein the sampling drum and a sampling rod of the pushing and pulling rod are respectively provided with scales so as to facilitate judgment and recording of a sampler for the sampling horizon and the sampling depth and realize accurate stratified sampling for a soil sample. The soil sampling device has the advantages that two modes of taking out the sample can be adopted, i.e., the sample is pushed out from a second end of the sampling drum by the pushing and pulling component or the sample is directly taken out by opening a door of the sampling drum, so that the soil sampling device is applicable to soil samples different in hardness.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a soil sampling device. Background technique [0002] The collection of soil samples is the foundation of soil scientific research and geological survey, and provides a material basis for the determination of the physical and chemical properties of soil samples. There are many methods for soil sampling. In the prior art, drill pipe sampling is generally used. When the drill pipe is drilled into the ground Finally, the soil formed a soil column in the drill pipe, and the entire soil column was taken out for analysis. The above-mentioned sampling drill pipe could not distinguish samples with different sampling layers and depths. [0003] In view of this, to overcome the above defects in the prior art and to provide a new soil sampling device has become a technical problem to be solved urgently in this field. Contents of the invention [0004] The object of the present inve...
