The sand-taped instrument of wriggling and move in a kind of earth's surface described in the utility model, this sand-taped instrument by suspension rod, messenger wire, suspention empennage, adopt husky device, sand inlet, counterweight, gas-permeable nets, fixing bucket, collection sandbag forms.Suspension rod (3) one end is connected with suspention empennage (5) by messenger wire (4), suspension rod (3) other end is fixed on a side of imbedding underground fixing bucket (7), suspention empennage (5) is fixed on the top of adopting husky device (1), the bottom of adopting husky device (1) is fixed with collection sandbag (8), and will adopt husky device (1) and put into fixing bucket (7).
Have sand inlet (2) adopting husky device (1) one side, the height of sand inlet (2) is 2.5cm apart from ground surface, adopt the opposite side fixed ventilation net (6) that husky device (1) is corresponding, in top sand inlet (2) one sides of adopting husky device (1), increase counterweight (9).
Fixing bucket (7) is imbedded underground, adopts the 0.5-1cm that is spaced apart of husky device (1) and fixing bucket (7) inwall, and suspention empennage (5) drives under wind-force effect to be adopted husky device (1) and freely rotate in buried fixing barrel (7).
Described sand-taped instrument is to be made by iron sheet and PVC material.
The sand-taped instrument of wriggling and move in a kind of earth's surface described in the utility model, the selected material of this sand-taped instrument is: adopt plug and pipe collar that husky device and fixing bucket are selected 160 pvc pipes, suspention empennage is selected common iron sheet, collection sandbag is selected common valve bag, and this sand-taped instrument is simple in structure, easy to make, sampling is convenient, carrying portable, be applicable to field wind erosion monitoring needs, greatly improved work efficiency, reduce labour intensity.
