A water evaporation device for remote sensing monitoring of soil moisture near the surface

Abstract

The invention discloses a water evaporation device for remote sensing monitoring of soil humidity near the surface, comprising: a pulverizer, a vacuum suction pipe, a controller, a material discharge port, a heating plate, a dispersing plate, a stirrer, a receiving antenna, and a stirring blade; The upper part of the machine is equipped with a material inlet, and the upper part of the material inlet is provided with a sealing cover, and the soil sample enters from the material inlet; the pulverizer is connected up and down, and the pulverizer crushes the soil sample into a powder; There are a large number of through holes on the surface, which vibrate and rotate at a low speed; the dispersion plate evenly distributes the powdery soil samples into the lower chamber; a vacuum suction pipe is connected to one side of the chamber, and when the vacuum pipe is working, the chamber is pumped out. Vacuum, to apply a vacuum to a powdered soil sample to remove moisture. The water evaporation device for remote sensing monitoring of near-surface soil humidity according to the invention has novel and reasonable structure, high working efficiency and wide application range of the equipment.

Description

technical field [0001] The invention belongs to the field of remote sensing monitoring soil humidity equipment, in particular to a water evaporation device for remote sensing monitoring soil humidity near the surface. Background technique [0002] Remote sensing monitoring of near-surface soil moisture. In recent years, scholars from various countries have conducted extensive research on estimating near-surface soil moisture and monitoring regional soil moisture based on satellite remote sensing. A correlation model between near-surface soil moisture and moisture. According to the differences in soil change factors and atmospheric environmental factors introduced in the related models, the direct correlation model between AOT and near-surface soil moisture, the correlation model considering the vertical distribution of aerosol and the influence of relative humidity, and the correlation model considering various environmental meteorological factors A model to calculate the ...
