Dust storm region of the present invention sand particle size and distributed number acquisition statistic device the course of work be：Timer starts to count
When, the pivot in driving device, the surface toughness of sampling testing paper 7, sampling testing paper 7 pass through shell to spool driving motor simultaneously
The grains of sand adhere to the tacky surfaces of sampling testing paper 7 when the vertical rectangular aperture 6 of body 1, and the sampling testing paper 7 for being stained with the grains of sand continues to move,
When moving to the part contacted with pressure sensitive recording paper 12, by the grains of sand trace on sampling testing paper 7 by squeezing contact history to pressure
In quick recording sheet 12, the pressure sensitive recording paper 12 of grains of sand trace continues to move on record, and pressure sensitive recording paper 12 moves at scanner 5
When, the grains of sand trace on pressure sensitive recording paper 12 is scanned into image by scanner 5, the source that can be subsequently scanned to scanner 5
Image processing for statistical analysis.In order to keep the image that scanner 5 scans apparent, set at the position opposite with scanner 5
It is equipped with backboard 4.
In all 8 shafts of apparatus of the present invention, contact support guide wheel 11 and resilient support 14 axis of guide wheel do not drive
Power, remaining 6 shafts by the same spool driving motor through belt transmission, due to sampling testing paper unreeling shaft 8 and sampling testing paper
Axis 9, pressure sensitive recording paper unreeling shaft 13 and pressure sensitive recording paper recycling axis 16 this two groups of shafts are recycled due to the shifting original of radius
Cause, therefore belt is selected, it not only ensure that the speed difference of recycling round and unlocking wheel, but also will not cause to misplace due to speed difference.
Finally it should be noted that the above content is merely illustrative of the technical solution of the present invention, rather than the present invention is protected
The limitation of range, those skilled in the art to technical scheme of the present invention carry out it is simple modification or equivalent replacement,
All without departing from the spirit and scope of technical solution of the present invention.
