Embodiment Construction
[0042] The measuring device 1 described in the present invention can be used to measure the amount of sand transported in a blown-sand creeping layer. The measuring device 1 comprises a cage 2, Figure 4 is a plan view showing the structure of the cage 2 . Such as Figure 4 As shown, the cage 2 has a plurality of insertion holes 201, three insertion holes 201 in this embodiment, of course, the number of insertion holes 201 can be changed in other embodiments. The insertion hole 201 is used to insert the collecting member 3 . In this embodiment, each insertion hole 201 is rectangular, and each insertion hole is arranged side by side and staggered in the longitudinal direction of the cage 2 , and the insertion holes are parallel to each other in the longitudinal direction of the cage 2 .
[0043] Figure 1 to Figure 3 It is a view showing that the collecting member 3 is inserted into each insertion hole 201 of the holder 2 . In this embodiment, three collecting components 3...
