Description

[Detailed description of the invention] [Industrial application field] The present invention is equipped with a grass collecting container at the rear of the machine body, and the cut grass from the mower provided in the machine body is delivered to the front side of the grass collecting container through a duct. The present invention relates to a grass collection container structure for a riding lawn mower, which is configured to feed grass into the grass collection container from a provided grass input port.

[Conventional technology]

As for the structure of the grass collection container of a riding lawn mower, for example, as disclosed in Japanese Utility Model Application Publication No. 60-94037, the grass collection container is constructed of highly breathable cloth, dustproof netting, punched steel plate, etc. Some plants are constructed so that the air from the mower escapes from the entire surface of the grass collection container.

[Problem that the invention attempts to solve]

As mentioned above, if the air from the mower goes out uniformly from the entire surface of the grass collection container, the grass clippings will be sent to the entire area inside the grass collection container at the same time, and the air will not be blown inside the grass collection container. Since the wind force is dispersed and weakened, it is no longer possible to fill every corner of the grass collection container with grass clippings.

The air from the mower also sends fine dust into the grass collection container along with the grass clippings, and this dust does not remain inside the grass collection container, but is blown outside the grass collection container along with the air from the mower. is discharged.

Therefore, if the grass collection container is configured as described above, dust will fly up above the grass collection container, which is not favorable from the viewpoint of work hygiene for the operator of the control section of the aircraft.

The purpose of this invention is to make it possible to pack as much grass clippings into the grass collection container as possible, and to prevent the dust coming out of the grass collection container from flowing toward the control section as much as possible. .

[Means for solving problems]

The feature of the present invention is that the structure of the grass collection container for a riding lawn mower as described above is configured as follows. In other words, a pair of ventilation openings are provided on the left and right upper surfaces of the grass collection container near the grass input port, and an ventilation opening is provided on the rear upper part of the grass collection container, and the air is discharged from the pair of ventilation openings on the top surface and the ventilation openings on the rear upper part. An exhaust passage is provided to guide the wind downward from the rear side of the grass collecting container, and an exhaust passage is provided at the lower front side of the grass collecting container between the left and right rear wheels on the aircraft side to guide the exhausted air to the lower side of the aircraft. There is a wind vent.

[Effect]

() If configured as described above, for example, Fig. 2 and Fig. 1
As shown in the figure, the cut grass that enters the grass container 7 from the grass input port 9a on the front side of the grass container 7 is accumulated from the rear bottom of the grass container 7, and is collected from the mower. Air is mainly blown out from the exhaust port 23 in the upper part of the rear part.

In this case, the air blown from the mower does not come out from the entire surface of the grass collection container 7, but mainly exits from the air outlet 23, so the wind power is not dispersed, and the wind power is directed toward the rear side of the grass collection container 7. The main focus will be on the bottom. Therefore, the rear bottom portion is sufficiently filled with grass clippings.

When the grass clippings accumulate on the bottom of the rear side of the grass collection container 7 and the exhaust port 23 at the upper rear portion is blocked, the air from the mower is discharged through the pair of exhaust ports 22 at the upper left and right sides of the grass input port 9a. The air then exits from the exhaust port 9b at the lower front side of the grass collecting container 7.

In this way, after the air exhaust port 23 in the upper part of the rear part is closed, the air from the mower goes around the left and right inner surfaces from around the rear center in the grass collection container 7 and makes a U-turn. The air exits through the exhaust ports 22 and 9b on the left and right upper surfaces and the lower front side. In this case, as described above, the wind force of the air is mainly concentrated on the left and right inner surfaces of the grass collecting container 7, so that the grass clippings are sufficiently packed into the left and right inner surfaces.

As described above, the grass clippings are piled up from the rear bottom of the grass collection container 7, the left and right inner surfaces, and the center bottom side of the grass collection container 7, riding on the air blown from the mower, and gradually approach the center of the grass collection container 7. It reaches the grass input port 9a.

() In the above process, the exhaust air and dust from the exhaust ports 23 and 22 in the rear upper part and left and right upper parts are
It passes through the air exhaust path 25 and is sent out to the lower part of the rear side of the grass collection container 7 which is farthest from the control section 4 shown in FIG. This prevents the above-mentioned exhaust air and dust from flowing toward the control section 4 side.

Then, the exhaust port 9b at the lower front side of the grass collecting container 7
Exhaust air and dust from the left and right rear wheels 2 on the aircraft side
Since the exhaust air and dust from the air outlet 9b are guided to the lower side of the fuselage between them, they are suppressed by the fuselage and the left and right rear wheels 2 and do not flow toward the control section 4 side.

[Effect of idea]

As described above, instead of exhausting the air from the entire surface of the grass collection container, by sequentially releasing the air from specific ventilation ports, the grass clippings can be packed sequentially from the rear bottom of the grass collection container. Finally, we were able to configure the container so that it reached the grass input port, which made it possible to efficiently pack the grass clippings into the grass collection container, thereby improving the efficiency of lawn mowing work.

In addition, the structure can be configured so that the dust coming out of the grass collecting container does not flow toward the control section as much as possible, and it is possible to improve work hygiene during lawn mowing work.
