Embodiment
As shown in figure 1, for outdoor portable wind erosion analogue means, by sample prescription peripheral frame, multi gear portable hair dryer, many
Root justifies chi and dust collection bag composition, and sample prescription peripheral frame is convenient for experimental calculation, preferably square-shaped frame, and its size is 1m*1m,
Many round chis are inserted on soil in sample prescription peripheral frame（Each chi deflation the thickness of the layer can be directly recorded, the later stage averages）,
The rear side of sample prescription peripheral frame is set provided with dust collection bag, the blowing mouth of the collection port correspondence multi gear portable hair dryer of dust collection bag
Put, dust collection bag is close to be positioned over after sample prescription peripheral frame.
To prevent the dust blown afloat to be scattering into its elsewhere, sample prescription frame side shield can be vertically arranged in sample prescription peripheral frame both sides, is kept off
The height of plate is difficult too high.
Meanwhile, shield can be laid on the soil on front side of sample prescription frame, it is opposite with dust collection bag to place, i.e., in blowing
Direction deviate from side.
Described positioning telescoping mechanism is not supported to hair-dryer, but can by its determination blower port and ground away from
Walk-off angle degree, it is ensured that front and rear experiment uniformity.
For outdoor portable wind erosion analogy method, device, principle and implementation method are as follows：
The first step：The design of multi gear portable hair dryer
The prototype based on the wind fire-extinguisher of forest fire prevention and control, air outlet bore is designed according to requirement of experiment（It is settable to have
The bore of different size）, air outlet ground height（On hair-dryer install positioning rule to measure air outlet away from ground away from
From）.In order to simulate different wind speed, wind fire-extinguisher throttle size is changed by machine rebuilding, that is, is provided with different
Air-out gear, realizes that air-out wind speed can be on multiple wind-speed gears such as 12-16-21-25-30m/s.
