The stainless steel barrel is provided with a connecting structure for preventing the dust collecting barrel from rotating, which is a slide-groove structure. On the one hand, it ensures the stability of the dust collecting barrel, and on the other hand, it facilitates the taking, placing and fixing of the dust collecting barrel, which is beneficial to high-altitude operation.

[0004] However, in the implementation process of the scheme, the area of the bottom of the dust collecting barrel is large, so when the atmospheric particulate matter settles on the bottom of the dust collecting barrel, it is relatively dispersed, and it is not convenient to take out the collected sediment in the subsequent process. Since the currently more precise weighing instrument is usually small in size, the dust collecting barrel is not easy to use on the more precise weighing instrument, so there are many inconveniences in the subsequent data measurement, and thus the meteorological tower atmospheric particulate matter deposition flux observation device is proposed.
