Description

Technical Field

[0001] The utility model relates to the technical field of soil detection equipment, in particular to a soil environment detection sampling device. Background Art

[0002] Soil is the basis of corn planting and production, and the quality of soil directly affects the growth and yield of corn crops. First of all, the detection of soil pH is very important. The acidity and alkalinity of the soil have a great influence on the growth of crops. Too acidic or too alkaline soil is not conducive to the growth of corn. By testing the pH value of the soil, we can adjust the pH value of the soil according to the results to provide a suitable growth environment for corn. Secondly, the detection of soil nutrient content is also very important. The nutrient content in the soil directly affects the growth and yield of corn. Therefore, before large-scale planting of corn crops, it is necessary to sample and test the planted soil in advance to understand the actual condition of the soil.

[0003] In the prior art, sampling devices are mostly motor-driven soil drills that rotate into the ground soil for sampling. However, when the soil drill is subsequently lifted, the soil drill is located in the borehole and the overall friction is large. Manual extraction is difficult and requires cooperation from multiple people. When multiple people exert force, the soil drill is unevenly stressed. The soil drill is also prone to scattering the soil inside during shaking. Therefore, we propose a soil environment detection sampling device to solve the above problems. Utility Model Content
