[0002] In the process of land space improvement, it is necessary to have a preliminary understanding of geological, climatic, economic and other factors. Geological factors require testing of local soil. The acidity and alkalinity of the land is an important criterion for whether the land can be used to grow crops.

During sampling, the patent places the sampling mechanism on a limiting disc and uses a closed top cover to limit the sampling mechanism. The driving motor inside the detection base drives the stirring connecting rod, supporting connecting column and limiting disc inside the detection cylinder to rotate, and the sampling mechanism is extended and retracted under the action of the thread, thereby realizing soil sampling. After sampling, the sampling mechanism is removed, and water is poured into the detection cylinder at this time, and then the driving motor is started again to stir the soil and water inside the detection cylinder, thereby realizing the pretreatment process of soil acidity and alkalinity detection, facilitating the subsequent detection and comparison using pH test paper, combining soil sampling and detection into one device, and improving the flexibility of the device.
