Description

Technical Field

[0001] The utility model relates to the technical field of soil solution extraction equipment, in particular to soil solution extraction equipment. Background Art

[0002] Soil solution is the liquid phase of soil, containing a variety of dissolved inorganic and organic compounds. Its composition and properties are constantly changing, influenced by the soil's parent material, climate, topography, and organisms, which in turn influence soil formation, development, and plant growth. Some substances in the soil solution can reduce the solution's surface tension to varying degrees, resulting in positive adsorption, while others can increase it, resulting in negative adsorption. Consequently, the composition and concentration of soil solution vary at different distances from the soil particle surface, providing root hairs with selective liquid phase locations. Too dilute a concentration prevents plants from receiving adequate nutrients; too high a concentration hinders water absorption; and excessive levels of harmful salts can cause soil salinization.

[0003] A soil solution extractor disclosed in the Chinese utility model patent application publication CN214472059U can automatically drill through harder soil for soil solution extraction by driving the drill bit through a height adjustment mechanism, saving time and effort, and can extract solutions from soils at different depths. However, when using this utility model, during the drilling process, the support column must first be hammered into the ground, otherwise it is easy to tilt. If it is not hammered into the ground, a manual hand-held device is required. In addition, during the drilling process of the drill bit, the entire device is subjected to a reaction force, which often makes it difficult to drill downward better. This will be detrimental to controlling the sampling depth and preventing tilting. In addition, during the downward drilling process, the shallow soil solution will first flow into the interior of the sampling tube, which often affects the sampling of deep soil solution and interferes with the accuracy of sample detection. Therefore, a soil solution extractor is urgently needed to solve the above problems. Utility Model Content

The upper surface of the fixed block 10 is located on one side of the motor 9 and is fixedly connected to the air suction pump 24. The outer surface of the sampling tube 16 is fixedly connected with a spiral blade 25.

[0028] In order to facilitate the directional extraction of soil solutions at different depths, Figures 1 to 6As shown, the present application adopts the following structure. Through the arrangement of the pedal 1, the bracket 3, the slide rail 4, the scale 5, the fixing frame 6, the screw rod 7 and the turntable 8, the soil solution extraction equipment has the effect of facilitating and better directional extraction of soil solutions at different depths.
