[0038] Embodiment:

[0039] Please refer to Figures 1-4The utility model relates to a soil environment detection device, including acidity detector 1, the right upper end of acidity detector 1 inserts the vertical rod 2, the outer end of vertical rod 2 is equipped with the positioning piece 3, the electrode head 4 of one side of positioning piece 3 is hung, electrode head 4 and acidity detector 1 between electrically connected, the right side end of acidity detector 1 is fixedly connected with the bottom plate 5, the upper end of bottom plate 5 is installed the rotary table spare 6, the upper end of rotary table spare 6 is equipped with a plurality of sample bottle 7, the right upper end of bottom plate 5 is installed the cleaning spare 8.

[0040] More specifically, the plurality of sample bottles 7 are three different pH calibrated buffer reagent bottles and three sets of soil parallel sample reagent bottles, wherein the pH values of the three buffers are 4.01, 4.68 and 9.18 respectively.

[0041] In use, the three sets of soil detection samples and the three sets of different pH calibrated buffer reagent bottles are placed above the rotary table spare 6, then the electrode head 4 is located in each different pH calibrated buffer reagent bottle under the adjustment of the positioning piece 3, and the values are recorded one by one. (When recording the value each time, the buffer reagent bottle is rotated under the drive of the rotary table spare 6, and the calibration operation is performed after standing for 5s.)

[0042] When detecting the pH value of the soil sample, the height of the electrode head 4 is first set in the soil suspension under the action of the positioning piece 3 (the soil sample is detected at the same height subsequently), then the detection parallel sample reagent bottle is rotated under the drive of the rotary table spare 6, and then the soil sample is detected after standing for 5s, and the pH values of the detected soil samples are recorded one by one.

[0043] Meanwhile, in this embodiment, the electrode head 4 is inserted into the cleaning spare 8 for cleaning after measuring the pH value each time. In this process, the pipeline is connected to the tank containing pure water, then the cleaning spare 8 cleans the inserted electrode head 4 by driving the water pump during the cleaning process, and then the electrode head 4 is wiped clean with filter paper, and then the next sample is measured.

[0044] In this embodiment, each parallel sample needs to be measured three times for the pH value and record the value, and the detection of the soil sample is completed.

[0045] Detection principle:

[0046] The scheme is to measure the pH of soil suspension by direct potential method, wherein the electrode head 4 is usually indicated by a pH glass electrode as an indicating electrode and a mercury electrode as a reference electrode. When the glass electrode and the mercury electrode or the composite electrode are inserted into the measured liquid, a battery reaction is formed, which produces a potential difference. Because the potential of the reference electrode is fixed, the size of the potential difference depends on the H + ion activity or its negative logarithm pH. Therefore, the electromotive force can be measured by a potentiometer, and then converted into pH. When a reversible hydrogen ion indicating electrode and a reference electrode are immersed in a solution at the same time, they form a primary cell. Under certain temperature conditions, the primary cell will generate an expected electromotive force within a certain time, and the electromotive force is proportional to the hydrogen ion activity of the solution.

[0047] The composite electrode is composed of a glass membrane, an internal reference electrode and an external electrode. The glass is a special glass material with high selectivity and sensitivity, which can respond to the change of ion concentration in the solution. By measuring the electromotive force of the measured solution, the pH value of the measured liquid can be obtained. The calculation of pH follows the Nernst equation, and the pH can be directly measured by an acidity meter.
