Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a grass collection device for collecting grass clippings cut by a mower.

(Prior art) For example, a mower tilting at the lower part of a running vehicle body such as a tractor is attached, a grass collecting device is attached to the rear of the vehicle, and grass clippings cut by the mower are sent to the grass collecting device via a blower device. A grass clipping device for collecting grass clippings in a grass collecting container is disclosed in US Pat. No. 40,540f93.

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 and flows out between the porous bag and the grass collection bag, and is also discharged from the porous bag to the outside.

In such conventional devices, a screen separates the grass clippings from the wind, and a porous bag collects relatively large dust (including fine grass clippings, the same applies hereinafter), but the porous bag has pores almost all over its surface. As the air flows out in all directions, fine dust is thrown up, worsening the environment for workers. 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.

This problem can be solved by forming a wind vent with one screen at the top of the grass collecting box, which is closed around the perimeter and has an open/close lid on one side, and converts the wind discharged only from this wind vent into air. This can be solved by separating the dust from the dust and storing the dust in a container.

(Problem to be Solved by the Invention) However, as described above, even if the air discharged from one mouth of the grass collection box is further separated and dust is stored, the dust will not be collected from the storage section. It is troublesome to take out the dust.

(Means for Solving the Problems) The present invention solves these various problems by removing the air from the wind outlet @1 of the grass collecting box aη having an opening/closing lid (30) to the screen α2.
The dust is separated from the wind and stored in the storage part B (to), and this dust storage part B (to) is connected to the grass collecting box (171) with an opening/closing lid that is opened and closed to discharge the grass clippings. −
