Background

The soil acidity and alkalinity refers to that various chemical and biochemical reactions exist in soil, and different acidity or alkalinity is shown. The acidity and alkalinity of soil are usually measured by the acidity and alkalinity. The soil is acidic and alkaline because of the small amount of hydrogen and hydroxide ions present in the soil. When the concentration of the hydrogen ions is greater than that of the hydroxide ions, the soil is acidic; otherwise, the solution is alkaline; when they are equal, the product is neutral. Plants can normally grow in a wide range, but various plants have proper pH values, so that the pH value of soil is detected in agricultural activities, and a soil sampling device is adopted to collect soil samples from the soil and convey the soil samples to a laboratory for detection and analysis.

However, the existing soil ph value sampling and detecting device also has some problems when sampling soil, firstly, the existing soil ph value sampling and detecting device can be gradually filled with soil of different depths when a sampling barrel goes deep into a specified soil layer for sampling, so that the sampling depth is limited, and the soil of different depths mixed into the sampling barrel can generate certain influence on the sampling sample, secondly, the existing soil ph value sampling and detecting device directly takes the sampling device deep into the soil layer for sampling when sampling, so that the vertical sampling of the sampling device can not be guaranteed to reach the specified depth, if the sampling device is inclined for sampling, the detection result is wrong, and if no auxiliary structure is used for assisting the sampling device, the huge rotating force generated by a motor when rotating can also influence the vertical sampling of the sampling device, and thirdly, the sampling barrel of the existing sampling device can not be replaced, is not conducive to cleaning.
