Description

Technical Field

[0001] The invention relates to the technical field of soil pH detection, in particular to a soil pH sampling device. Background Art

[0002] The acidity and alkalinity of soil, also known as "soil pH", is an indicator of the strength of the soil's acid-base reaction. It is usually determined by the concentration of hydrogen ions and hydroxide ions in the soil solution and is expressed as a pH value. Soils with a pH between 6.5 and 7.5 are considered neutral, below 6.5 are acidic soils, and above 7.5 are alkaline soils. The acidity and alkalinity of soil have an important impact on plant growth because it is a key factor in plant nutrient availability. Most plants have specific requirements for the acidity and alkalinity of soil. Some plants prefer neutral to slightly acidic soils, while others prefer neutral to slightly alkaline soils. Therefore, it is crucial to understand the acidity and alkalinity of the soil and adjust it according to the needs of the plants. Methods for adjusting the acidity and alkalinity of the soil include applying lime or ferrous sulfate to raise or lower the pH, and using organic fertilizers and microbial organic fertilizers to improve the acidity and alkalinity of the soil. When adjusting the acidity and alkalinity of the soil, care should be taken to choose appropriate methods and materials to avoid adverse effects on plants. The strength of soil acidity and alkalinity is often measured by pH, which is expressed as pH value. To determine the pH value of soil, the electrode method or litmus paper colorimetry is often used. The electrode method is fast and accurate, but it is rarely used at present. The litmus paper colorimetry method is simple to determine the pH value of soil. When determining the pH value of soil, seedbed and nutrient soil, you can first take a sample of soil, put it in the bottom of a bowl, then add 2.5 parts of distilled water, stir it thoroughly with a glass rod for 1 minute, wait for it to stand and clarify, and then immerse a section of test paper in the clear liquid. The test paper will change color. Immediately compare the color-changing test paper with the pH standard colorimetric card to directly obtain the pH value.

[0003] When the existing soil sampling device is in use, such as application number CN202010986448.0, which discloses a rapid sampling and detection device for soil pH for soil remediation, it includes two support columns, the tops of the two support columns are fixedly connected with handles, a connecting column is fixedly connected between the inner walls of the middle parts of the two support columns near one end of the handle, a soil sampling tube is arranged between the inner walls of the bottoms of the two support columns, a plurality of second circular holes are symmetrically opened on the outer wall of the soil sampling tube, a clamping ring is slidably sleeved on the outer wall of the soil sampling tube, and two symmetrically distributed connecting shafts are fixedly connected to the outer wall of the clamping ring, and the ends of the two connecting shafts facing away from the clamping ring are rotatably connected to the support columns at corresponding positions. The advantage of the present invention is that a clamping ring is fixedly sleeved on the outer wall of the soil sampling tube, the outer wall of the clamping ring is rotatably connected to the support column through a connecting shaft, and the outer wall of the clamping ring is screwed and connected with a tightening bolt, so that the soil sampling tube can be moved up and down to sample soil at different depths; however, in the above technology, when encountering hard soil, it is difficult to perform efficient sampling, and manual operation is unable to penetrate deep into the soil layer. For this reason, we propose a soil pH sampling device to solve the above problem. Summary of the invention
