Example Embodiment

[0015] Example: see Figure 1-3 , the present invention is a soil topsoil stratified sampler, including a fixing device and a cutter device for cutting the surface soil sample, the fixing device is an iron pipe with an inner diameter of 3cm and a length of 50cm, which is rounded at the top and pointed at the bottom. During the sampling process Insert the lower tip into the soil about 30cm to fix the whole device, so as not to shake the cutting blade device up and down and affect the sampling quality.

[0016] The cutter device for cutting the surface soil sample is the main device of the surface soil sampler. The device divides the soil layer with a depth of 10cm into 8 layers, among which the 2cm soil sample in the topmost layer is divided into 4 layers on average, each layer is 5mm, and the 2-10cm soil is evenly divided into 4 layers according to the depth, and each layer is 2cm. The blade is a 90° arc-shaped sharp iron piece with a radius of 15cm. One end uses a circular ...

Abstract

The invention belongs to the technical field of ecological study of soil science, environment science and the like, and discloses a surface soil laminating sampler. The surface soil laminating sampler comprises a fixing device and a cutter device, wherein the cutter device is used for cutting a surface soil sample; the fixing device is an iron pipe which is 3cm in inner diameter and 50cm in length and has a round upper part and a sharp lower part; the sharp lower part can be inserted into soil by about 30cm during a sampling process, so that a whole device can be fixed, and the cutter device is unlikely to shake up and down to affect the sampling quality. According to the surface soil laminating sampler disclosed by the invention, the sampling depth can be accurately controlled, soil is clearly laminated, no compaction is generated, and no cross-containmination is generated between different levels of samples.

Description

technical field [0001] The invention relates to a soil sampling device, in particular to a soil topsoil layered sampler, and belongs to the technical fields of ecological research such as soil science and environmental science. Background technique [0002] Existing samplers mainly use stainless steel shovels or scrapers of different depths to collect soil samples. The stratification is not accurate, and it is easy to cause mutual contamination of soil samples at different levels. In the process of scraping the soil, it is easy to cause compaction of the soil and affect the analysis. layer accuracy. In view of the above problems, the present invention proposes a surface soil sampler capable of precisely controlling the sampling depth, without compaction, and without mutual pollution between samples of different layers. Contents of the invention [0003] The technical problem to be solved by the present invention overcomes the existing defects, and provides a layered soil ...
