The invention relates to the technical field of soil property measurement, in particular to an automatic measurement device for saturated hydraulic conductivity of soil. The device comprises a water supply assembly and a measuring assembly, wherein the measuring assembly comprises a permeation water collecting component, a leakage water collecting component and a counting component; the water supply assembly is connected with the permeation water collecting component, the leakage water collecting component comprises a rotating shaft and a plurality of collecting containers, openings of the collecting containers are located below a water outlet of the permeation water collecting component, the plurality of collecting containers are arranged on the outer wall of the rotating shaft circumferentially and uniformly and turn over slantwise after being filled with a preset amount of water to drive the rotating shaft to rotate, and touch rods in one-to-one correspondence with the collecting containers are arranged on the rotating shaft; the counting component comprises a recording pen and a recording paper device, and when the touch rods rotate, the recording pen can be shifted to mark on recording paper conveyed by the recording paper device at constant speed. The device omits the human operation of reading and measuring when the amount of permeation water is measured, random errors caused by human reading are also avoided, the measurement precision is high, actual operation and use are facilitated, and the measurement efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of measuring soil properties, in particular to an automatic measuring device for soil saturated hydraulic conductivity. Background technique [0002] Soil saturated hydraulic conductivity refers to the amount of water passing through a unit area per unit time when the soil is saturated with water. Different regions have different soil properties, topographical conditions, different soil depths, and vegetation types, all of which have different degrees of influence on soil saturated hydraulic conductivity. In addition, it is also related to soil texture, structure, salt content, and water content. The determination of soil saturated hydraulic conductivity has important scientific significance for further understanding of soil physical properties. [0003] At present, the most commonly used method for determining soil saturated hydraulic conductivity is the indoor ring knife method. The principle is to take ...
