Soil solution automatic extraction control device

Abstract

The invention discloses a soil solution automatic extraction control device which comprises a vacuum filter (1), a guide tube (2), a loading mechanism (3), a gas tube (4), a suction pump (5), a controller (6), a liquid level detector (7) and an analog-to-digital converter (8), wherein the loading mechanism (3) is provided with a first opening and a second opening; the vacuum filter (1) is connected to the first opening of the loading mechanism (3) through the guide tube (2); the second opening of the loading mechanism (3) is connected to a suction opening of the suction pump (5) through the gas tube (4); the liquid level detector (7) is arranged in the loading mechanism (3); the liquid level detector (7) is connected to the analog-to-digital converter (8); and the analog-to-digital converter (8) and suction pump (5) are respectively connected with the controller (6). By performing the automatic control suction and liquid level detection, the detection functions of the device are added; and the device is automatic, so that the extraction process is more accurate, thereby enhancing the extraction efficiency.

Description

technical field [0001] The invention relates to a soil solution automatic extraction control device, which belongs to the technical field of soil detection equipment. Background technique [0002] Soil is formed by a combination of smaller soil particles, its structure is loose, and there are many pores in the soil, which contain a variety of liquids, and these liquids play a decisive role in the growth and development of plants. Therefore, in planting Previously, it was particularly important to identify the liquid-containing components of soil. [0003] Soil solution is generally defined as soil interstitial water containing solutes and dissolved gases, and it is the site where soil chemical reactions and soil formation processes take place. The concentration of each element in the soil solution is a quantitative index reflecting the presence of the element in a mobile ion state. Generally, only the most active part is dissolved in the soil solution, which is prone to oxi...
