Description

[Detailed Description of the Invention] [Industrial Field of Application] The great invention is that the grass clippings are fed into the grass collection container through the grass t-duct from the mower 1 with the grass collection container in a reclined position at the rear of the machine body. Along with configuring.

The grass collecting container can be moved rearward by placing support shafts protruding from both sides of the grass collecting container on a pair of guide rails extending toward the rear of the machine, and the grass collecting container can be moved rearward in the vicinity of the guide rails. The present invention relates to a grass collection container support structure for a riding lawn mower, which is capable of rotating around the axis of a support shaft cr1''.

[Conventional technology]

The reason why the grass collection container is rotatably supported around the horizontal axis as described above is that when the grass collection container is full of grass clippings, the lid part of the grass collection container can be turned upward or downward@f'KI. 'The structure is designed to make it easier to take out the grass clippings in the grass collection container by changing the posture.The reason why the grass collection container is moved backward is that when the posture is changed, a part of the grass collection container collides with the rear of the aircraft. This is to ensure space for rotational operations to prevent this from happening.

If the grass collecting container is moved back to a position where its posture can be changed by rotating the container, it is necessary to hold the supporting shaft of the grass collecting container in order to perform the rotating operation at that position, and the rear end of the guide rail is There is a model in which the support shaft of the grass collecting container is supported by being provided in a recessed portion nearby and the support shaft of the grass collecting container is dropped into this recessed portion, and the grass collecting container is rotated at this position.

[Problem that the invention seeks to solve]

With the above structure, when the support shaft of the grass collection container moves on the guide rail and falls into the recess, an impact is inevitably generated. In particular, when the grass collection container is full of grass clippings, the weight IIk of the grass collection container is considerable, so the above-mentioned impact force is expected to be particularly large, and this impact Due to the strength of the guide rail, which directly receives the force,
It has a sparse structure.

The present invention has focused on this problem and aims to provide a structure in which the above-mentioned impact force is not generated.

[Means for solving problems]

The uninvented feature is that the above-mentioned grass collection container support structure for a riding lawn mower is provided with a member that elastically engages and holds the support shaft 2 of the grass collection container near the rear end of the guide rail. Its action and effects are as follows.

[For production]

When the above-mentioned member is thrown, when the grass collection container is moved backward along the guide rail, the support shaft of the grass collection container is not dropped.

No percussive movement occurs in this case, since it is held in position by the elastic engagement of said parts.

〔Effect of the invention〕

As mentioned above, when the grass collecting container is moved to a position where the posture can be changed in the above-mentioned riding lawn mower, it is now possible to prevent the generation of an impactful force, and to improve the strength of the guide rail. This has resulted in improved safety.

〔Example〕

Hereinafter, uninvented embodiments will be described based on the drawings.

As shown in FIG. 6, the telescope is supported by front wheels +11 and rear wheels (2), and has an engine (3) at the front and a control section (4) at the center, and both wheels fi+, 12+.
The mower (51) is equipped with a mower (51) between the mowers (51 and 51), and the grass cut by the mower (51) is sent through a duct HEi+'i to a grass collection container +71 vc at the rear of the dust body. .

As shown in FIGS. 4 and 5, the grass collection container (7) has a cylindrical shape with a bottom and is composed of a resin-molded body (8) and a lid (9), and the lid (9) is shown in the figures. As shown, approximately the lower half is opened as an air outlet (9b), and the upper half is also provided with a grass input port (9a).

Then, a mesh body Uα is stretched on the inner surface of the lid (9), and radial cuts are made in the grass inlet (9a).
is provided. The cover body (9) constructed as described above is fixed to the rear part of the fuselage via the cover plate t2 as shown in FIG.
is inserted, and the grass collection container (2019) is operated in a 9-forward position as a whole. Then, the grass cut by the mower (6) is carried by the air from the mower (5) and sent from the duct (6) into the grass collecting container (), and the air from the mower (6) is carried by the lid (). In 9), the ventilation blower thrown at the opening (9b) and the top surface of the main body, etc., exits from the container.

When the grass collection container ()) is full of cut grass, the grass collection container () is filled with grass clippings.
Only the main part (8) of 7) is moved rearward and rotated around the axis of the support shaft α force, which will be described later, to discard the grass clippings in the main part (8).The structure will be described in detail. Then, as shown in Figures 1 and 2, the grass collection container (7) is roughly (

@ From the state shown in Figure 1, when the manual operation lever aη is operated downward, the link (16) and the crank member (141
The grass collection container (7) is rotated downward by the action of Since the structure is such that the crank member (I41) does not rotate at the position of the fixed line in Fig. 1, it is assembled by operating the manual operation lever aη. The main body (8) of the grass container (7) moves completely rearward on the guide rail 031 while remaining in the forward leaning position.

As shown in FIGS. 1 and 3, near the guide rail α11, a member formed by fully bending a plate spring is provided,
At this position, the roller (12a)' of the support shaft α2 (elastically held and held).

Further, in this position, the guide capital 09) is moved in a jumping manner, and in this position, it is rotated downward by the cooperation of the (8) link 051 and the crank member Q4). In addition, this series of operations is reversible, and by manually operating the lever t and returning it, the member (8) is returned to its original position and the crank member 0 is rotated.
The connecting bottle 011) in (4) can be inserted into the guide Qfll again and returned to the state shown in FIG. 1.
