Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a grass collector.

(Prior art) As shown in U.S. Pat. No. 4,054,023, a grass collector has a mower and a grass collection container attached to a traveling vehicle body, and the grass cut by the mower is collected by a feeding device. Feed the grass into the container and place it on the top of the grass collection container.
Some devices are equipped with a discharge port for discharging the air fed to the grass collecting container together with the grass clippings from the feeding device to the outside, and the discharge port is equipped with a screen to prevent the grass clippings from passing through.

By the way, in the above-mentioned conventional method, the front and rear surfaces, both side surfaces, and the bottom surface of the grass collection container are covered with a porous bag body, and the air from the outlet is blown out from the entire bag body.

For this reason, in the above-mentioned conventional method, the dust contained in the air from the outlet also blows out from the entire bag body, and the worker is surrounded by this dust, making it difficult to work comfortably. There were hygiene issues.

The above problem was particularly noticeable when working on dry days.

In order to solve this problem, a method has already been proposed in which the dust-laden air discharged from the grass collection box is circulated again to the mower's cutting section to prevent the dust from being spread outside. (For example, see Utility Model Application Publication No. 112754/1983).

(Problems to be Solved by the Invention) The device described in the above-mentioned Japanese Utility Model Application Publication No. 49-112754 is configured to circulate the exhaust air in a closed loop, which prevents dust from scattering. The conventional mower is a small walking mower, and if this technology were applied to a large riding mower, a large closed loop duct would be required, which would complicate the structure and be undesirable.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a grass collector that has a simple structure, can be applied to large mowers, and does not scatter dust.

(Means for Solving the Problems) In order to achieve the above object, the present invention takes the following measures. That is, the feature of the present invention is that a mower and a grass collecting container are mounted on a traveling vehicle body, and the grass clipped by the mower is fed to the grass collecting container via a feed pipe by an air flow. In a grass collector, the container is equipped with a screen for separating the air supplied to the grass collection container together with the grass clippings and discharging it to the outside of the grass collection container. A guide member is provided which guides the container downward along the outer surface of the container, and an air outlet is provided between the lowermost end of the guide member and the outer surface of the grass collection container to blow air from the screen downward, and the air outlet is provided with a guide member that guides the grass downward along the outer surface of the container. The screen is provided with an openable and closable lid that allows air to pass through the screen, but traps small pieces of grass that have passed through the screen, and maintains the closed state using elastic force.

(Function) According to the present invention, the grass clipped by the mower is fed to the grass collection container via the feed pipe by the air flow.

The air fed to the grass collection container together with the grass clippings is separated from the grass clippings through a screen, is directed downward between the guide body and the outside surface of the grass collection container, and is directed downward between the lowermost end of the guide body and the outside surface of the grass collection container. It blows out downward from the outlet.

The air outlet is provided with a lid, and among the air and dust passing through the air outlet, only the air passes through the lid and is discharged to the outside, and the dust is captured by the lid. The lid is configured to maintain its closed state using elastic force, so if dust accumulates on the lid, the air passage hole will become clogged, and the lid will automatically close due to the air flow. It is pushed open and the accumulated dust is discharged. When the dust is discharged, the lid body is automatically closed by elastic force. In other words, dust such as small pieces of grass is collected in a lump and automatically discharged periodically, so that it is not scattered around.
