[0026] Working principle:
[0027] Step 1: When sandy soil is loaded, the soil particles exert a lateral outward pressure on the rubber nipple 23, which is offset by the elasticity of the rubber nipple 23 itself, so that the soil particles are retained and will not be lost. When the soil extractor probe 26 is embedded in the rubber nipple 23, the soil extractor probe 26 exerts a lateral force on the rubber nipple 23, causing the rubber nipple 23 to be sunken inward. Due to the good elasticity and flexibility of the rubber nipple 23, the surface of the rubber nipple 23 is opened and embedded in the soil extractor probe 26, so that the soil is successfully extracted. When the soil extractor probe 26 is taken out, the rubber nipple 23 will recover at the same time as the soil extractor probe 26 is pulled out due to its good elasticity and flexibility. The cross-section of the soil extractor probe 26 used in the experiment is elliptical. Increase the contact area with the rubber nipple 23 to reduce the pressure and avoid scratching the rubber nipple 23. The soil filling height is 100 cm. Opposite soil sampling pipes 22 are set every 10 cm of soil layer to carry out soil stratification sampling. The top 10 cm is reserved for the soil column body 21. In order to prevent the water that is not absorbed by the soil in time from flowing out from the upper part of the soil column body 21 during the watering process of the upper part of the soil column body 21, a permeable baffle 24 and a drain hole 25 are set to ensure that the water will not accumulate in the lower soil after watering, thereby simulating the water and fertilizer migration in the vertical direction of the soil, which can effectively prevent the leakage of sandy soil and ensure that the upper and lower soil layers of the soil column are not disturbed, so as to obtain the advantages of pollution-free soil stratification samples;
[0028] Step 2: When adjusting the height of the soil column experiment assembly 2, the experimenter turns on the first motor 15, and drives the threaded rod 19 to rotate through the first motor 15, so that the slider 13 drives the mounting seat 16 to move upward, thereby adjusting the height of the soil column experiment assembly 2, which is convenient for the experimenter to sample the wind-blown sandy soil. When rotating and adjusting the position of the soil column experiment assembly 2, the experimenter turns on the second motor 17, and drives the water basin 18 to rotate through the second motor 17, thereby facilitating the adjustment of the position of the soil column experiment assembly 2.
