Description

[Detailed description of the invention] [Industrial application field] The invention relates to a riding lawn mower equipped with a grass collection container, and more specifically, the invention relates to a riding lawn mower equipped with a grass collecting container. A support arm extending rearward is connected to the support arm, and a peripheral frame provided around the opening of the grass collection container opened upward is placed on the support arm,
The present invention relates to a structure of a grass collecting section of a riding lawn mower, in which an upper cover covering a container opening is mounted and fixed on the peripheral frame, and grass clippings from a mower are blown and guided to the grass collecting container.

[Prior Art] In the above-mentioned conventional lawn mower, the peripheral frame and support arm of the grass collection container are made of metal pipes, etc., and the plastic upper cover is placed directly on the peripheral frame. I was trying to do that.

[Problem that the invention attempts to solve]

However, when collecting grass clippings at the end of work, if the grass collection container is removed and the surrounding frame is manually carried by hand, the surrounding frame may bend and deform due to the weight of the grass clippings.

When such a curved frame is reattached to the lawn mower, a gap will be created between the frame and the upper cover, and fine dust from the grass cut during lawn mowing will be trapped between the frame and the upper cover. Problems have arisen in that the particles pass through the road and land on the driver, hindering the driver's work and being unfavorable from a sanitary standpoint.

As a method for solving the above-mentioned problems, for example, the surrounding frame may be made of a strong rigid material to prevent bending deformation, or a shielding member may be provided between the driver's seat and the grass collecting container. However, there were drawbacks such as the increased weight of the device and the need for major structural improvements.

The purpose of the present invention is to prevent fine grass clippings from falling on the driver by an extremely simple improvement that adds a member that is easy to install and has a simple structure.

[Means for solving problems]

The characteristic structure of the present invention is that a sealing member is interposed between the peripheral frame and the upper cover at least in the area facing the driver's seat, and a ventilation part is provided at the rear of the upper cover. is as follows.

[Effect]

When the cut grass is conveyed and guided to the grass collection container by the blowing force of the mower, the grass is collected into the grass collection container due to its weight, and the conveyed exhaust air is discharged outward from the rear ventilation part along with fine dust. is discharged. At this time, the surrounding frame of the grass collection container, which is placed and supported on the support arm and is sandwiched and supported by the upper cover that is fixed in the placed state from above, is exposed to the weight of the grass during the collection work of the grass clippings. Even if the grass is deformed due to bending, the elastic deformation of the sealing member interposed between the peripheral frame and the upper cover can close the gap caused by the deformation and prevent fine grass debris. etc. can be prevented from falling on the driver's seat side.

Furthermore, the peripheral frame placed and supported by the support arm can be effectively held down and supported by the load of the upper cover due to the frictional resistance of the seal member made of an elastic material.

[Effect of idea]

As a result, by making rational improvements, we created a structure in which the grass collection container can be easily attached and detached to facilitate the collection of lawn mowing debris, while also preventing fine dust from falling on the driver's seat side. In addition to improving the environment, it has become possible to suppress as much as possible the displacement of the grass collection container caused by machine vibration.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 4, running wheels 1 and 2 are mounted on the front and rear of the aircraft, and power from a vertical shaft type engine 3 mounted in the front is transmitted via a power transmission belt 4 and a transmission 5. The driving force is transmitted to the rear wheels 2, and a driver's seat 7 is provided at the rear of the upper part, and a mower 6 is disposed below the body between the front and rear wheels 1 and 2 so as to be able to move up and down. A riding type lawn mower is equipped with a grass collection container 8 for storing grass waste cut by the mower 6.

The mower 6 is equipped with a bar blade 10 which is rotatably driven by the power of the engine 3 transmitted through a transmission belt 9.
The grass debris cut by the bar blade 10 is guided into the grass collection container 8 through the grass collection duct 11 by the rotational wind force of the bar blade 10.

As shown in FIG. 3, the grass collection container 8 has a pair of left and right frames 12, which are erected from the rear of the base.
A peripheral frame 14 provided at the periphery of the opening of a fine-mesh grass collection container 8 that opens upward is placed on top of a support arm 13 that is fitted and connected to the upper end opening of 12 and extends rearward in a substantially E-shape. The upwardly protruding piece 17 of the support arm 13 is engaged with the locking hole 16 of the locking tool 15 which is provided and protrudes from the surrounding frame 14, and the grass collection container 8 is removed to the rear. It's stopped. Furthermore, a plastic upper cover 18 covering the opening of the grass collection container 8 is mounted and fixed from above.

That is, engagement pins 20, 20 are provided on support parts 19, 19 extending forward from the tops of the frames 12, 12, protruding toward the right side of the body.
Locking tools 21 and 2 fixed to the front part of the upper cover 18
The locking holes 22, 22 of 1 are connected to the engaging pins 20, 20.
It is fitted externally. Therefore, the upper cover 18 is swingably attached around the axis P of the engagement pins 20, 20, and the front end of the upper cover 18 is fixed by the elastic fixing member 23 attached to the central rear end of the support arm 13. It is tensioned and fixed.

The support arm 13 includes a substantially U-shaped pipe member 24 and an intermediate receiving member 2 whose upper part is formed flat.
5, and two grass collection containers 8 can be attached to the two air spaces formed by them. As shown in FIGS. 1 and 2, a sponge-like elastically deformable seal member 26 is provided at a lower portion of the upper cover 18 corresponding to the pipe member 24 and in contact with the peripheral frame 14.
is attached to the rear side of the upper cover 18.
It extends rearward from the rear end of the grass collecting container 8, and forms an air vent part 27 for blowing air by the rotary cutting blade 10.

By providing the sealing member 26, it is possible to prevent fine grass debris from being blown out toward the driver's seat 7 from between the peripheral frame 14 and the upper cover 18 of the grass collecting container 8. Further, the sealing member 26 can also absorb variations in dimensional errors between the peripheral frame 14 and the upper cover 18, and has the advantage of having a buffering effect.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
