Description
Technical Field
The utility model belongs to the technical field of soil sample collection, and relates to a soil sampler capable of protecting the original state of a soil sample.
Background
When the soil is detected by various physical and chemical indexes, the detection result is related to the quality of the selected point, and the soil sampling device has non-negligible influence on the selected point. When surface soil is sampled, a common sampling device is a cutting ring or a small shovel, however, when deeper soil is sampled, a soil drill is often used for sampling, because the monitoring of the physical and chemical properties of the soil has higher requirements on the accuracy of index results, the soil detection has the defects that the requirements on the original state of the soil are not high for the detection of various elements, ions, microorganisms and the like, the water content, the density, the strength parameter, the deformation parameter, the consolidation compaction parameter and the like, and the detection of the indexes has higher requirements on the sampled soil sample. If the soil sample is disturbed, the detected index result may not be in accordance with the actual result, or even a larger error occurs, so that the soil is required to be the original soil during detection, namely the soil taken back from the field should keep the natural structure, if the structure of the sample is damaged, the soil sample needs to be re-sampled to meet the requirement to perform the index detection, and when the soil sample is collected, the soil sample is very easy to be disturbed, so that the collected soil sample becomes a waste sample.
After soil sampling is completed, the common soil sampling device pushes out a soil sample from the soil drill through the sample pushing rod, and the soil sample is collected. However, most earth drills take out soil by the friction force between the soil and the drill bit, and when the sample pushing rod pushes out the soil sample, the friction force between the soil and the drill bit needs to be overcome, so that the sample pushing rod is easy to extrude the soil sample by overcoming the friction force, the natural structure of the soil sample is damaged, and the soil sample may become a waste sample.
The soil sampler can overcome the step of pushing a soil sample out of the soil drill by using the soil pushing rod to collect the soil sample by improving the composition structure of the sampler, thereby avoiding the problem of inaccurate detected index result caused by damage to the natural structure of the soil sample due to extrusion of the soil sample caused by the fact that the soil pushing rod overcomes the friction force between the soil and the drill bit, ensuring the natural structure of the soil sample and improving the accuracy of the index detection result of the soil sample.
