[0002] The media objects of environmental testing can be roughly divided into water quality testing, air testing, soil testing, solid waste testing, biological testing, etc. A Chinese patent discloses a surface soil stratification sampling device (authorization announcement number CN108844772B). This patent technology discloses a surface soil stratification sampling device, which relates to the field of soil sampling technology. The invention includes a tool and a bucket, and a U-shaped frame is provided in the bucket; a T-shaped slot is provided on both end faces of the U-shaped frame, and a plurality of elastic mechanisms are arranged on the bottom side of the bucket at the opening of the T-shaped slot; a T-shaped slider is provided on one side face of the tool to match the T-shaped slot; a baffle is provided on the top side face of the tool; a blind hole is provided on the bottom side face of the tool and the bottom side face of the T-shaped slider to match the top of the elastic mechanism; the tool is fixed to the U-shaped frame by a fixing screw and a fixing block; the output shaft end of the fixing screw is provided with a groove that rotates with the column; a T-shaped block is provided on one surface of the fixing block to match the T-shaped slot. The present invention uses a bucket to sample the surface of the soil, and uses a cutter to scrape off the loose soil and debris on the surface of the soil, thereby achieving the removal of loose soil and debris on the surface of the soil while sampling the surface soil. This patented technology solves the problem of soil sampling during soil testing. Soil sampling refers to the method of collecting soil samples, including the layout of the sampling and sampling technology. When sampling the surface soil of the ground, the existing sampling device needs to manually clean the loose soil and debris on the surface of the soil before sampling; or separate and remove the unnecessary loose soil and debris before testing after sampling; the sampling method of this sampling device is cumbersome to operate, and the manual cleaning of loose soil and debris on the surface of the soil can easily destroy the surface structure of the soil, thereby affecting the accuracy of soil sampling.

[0003] However, in the prior art, when soil is sampled, the cooling requirements for soil collection and detection at different heights from the ground are different, and it is necessary to solve the problem of sampling and quickly removing soil at different heights.

[0004] Therefore, those skilled in the art provide a surface soil vertical layer sampling device to solve the problems raised in the above background technology. Utility Model Content
