Abstract

The invention discloses a portable sand and dust separating and sampling device for ground surface sand and dust substances. The portable sand and dust separating and sampling device mainly comprises a ground surface sand and dust sampling box, a sand and dust conveying pipe, a drawer type sand collecting box, a drawer type dust collecting box, an electric fan and a square column-shaped four-layer structure. The device is clear in principle and simple in structure, adopts a rechargeable battery as power, can simulate different near-surface wind speeds, separates surface sand grains and dust grains blown by wind, and respectively measures the sand content and the dust content of the surface per unit area. The portable earth surface sand and dust substance field investigation sampling device is mainly used for scientific research and experimental observation of sand storm problems, and test data of the portable earth surface sand and dust substance field investigation sampling device is used for sand storm early warning and forecasting and sand storm disaster evaluation.
