A grass clipping device for collecting grass clippings in a grass container is disclosed in U.S. Pat. No. 4,054,025.

The grass collecting container of the conventional grass collecting device has a grass collecting bag arranged inside a flexible porous bag, a brush screen is provided on the upper part of the grass collecting bag, and the grass is fed above the grass collecting bag. The structure is such that the air passes through the screen, flows out between the porous bag and the grass collection bag, and is discharged from the porous bag to the outside.

<Problems to be solved by the invention> This conventional device separates grass clippings from the wind with a screen,
Porous bags can collect relatively large amounts of dust (including fine grass clippings, the same applies hereinafter), but porous bags have pores on almost the entire surface and air flows out in all directions, so fine dust can fly up and become difficult to work with. It is deteriorating the environment for people. In order to remove fine dust, the pores of the porous bag can be made smaller, but this will cause pressure loss and clogging, making it difficult for air to flow out.
