Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a grass-collecting container for a lawn mower, and more specifically to a grass-collecting container on a pair of support arms that cantileverly project from a container support frame. The present invention relates to a grass collecting mechanism for a lawn mower, which is hung by mounting the mouthpiece part of the above, and the upper part of the grass collecting container is covered with an openable and closable cover, and a grass turf conveying duct is connected to this cover.

[Conventional technology]

Conventionally, like the one disclosed in Japanese Patent Laid-Open No. 63-105607, the grass container is hung by simply placing the mouthpiece part around the upper end thereof on the support arm of the support frame. The cover provided to collect the cut grass in the grass collecting container was also simply covered on the upper part of the container to cover the opening of the grass collecting container.

[Problems to be solved by the device]

In the above-mentioned conventional technique, when the grass is collected in the grass container and becomes heavier, the mouthpiece of the grass container is distorted inward, or the support arm of the support frame is bent outward, or this Due to both phenomena, there is a possibility that the grass collection container may come off the support arm.

An object of the present invention is to devise a grass-collecting mechanism in a lawn mower so that the grass-collecting container does not come off from the support arm even if the grass-collecting container becomes heavy due to the collected grass.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a regulating member for preventing lateral movement between the support arm and the mouthpiece inside the cover in the grass collection mechanism of the above-mentioned lawn mower when the cover is set. Is provided as a characteristic configuration.

[Action]

According to the above configuration, when the cover is set, the relative lateral movement between the mouthpiece portion of the grass container and the support arm can be automatically regulated.

[Effect of device]

Therefore, even if a large amount of grass such as grass is stored in the grass container and becomes heavy, the mouth of the container and the support arm are kept so as not to be separated from each other, so that the mouth part of the grass container is I was able to eliminate the risk of moving laterally from the support arm and coming off.

〔Example〕

As shown in FIG. 3, the riding lawn mower includes an engine (1) at the front of the machine body, a mission case (2) at the rear of the machine body, a driving operation unit (3) between them, and front and rear wheels (5 ), (6) between the mid-mount mower (7) and the mower (7), which is an external rotation type that guides the grass clippings from the mower (7) to the grass collection container (8) as a work attachment connected to the rear end of the machine. It is configured with a grass collection duct (9).

As shown in FIG. 5, the duct (9) has a tubular mounting portion (11) formed on the support frame (4) at a substantially central portion between the mower (7) and the grass container (8). Duct guide (12) inserted and fixed in
It is supported so as not to move downward. This guide (12) has an annular ring (13
The duct is surrounded by (A), and the pipe (13B) bolted to this ring (13A) is configured to be inserted into the mounting portion (11). This prevents the clogging of the duct due to that.

Next, the grass collection mechanism will be described.

As shown in FIG. 1, FIG. 2 and FIG. 4, the outer cradle (14), (14) and the central cradle (15), which are support arms projecting cantilevered from the container support frame (4). While suspending the grass collection container (8) by placing the mouthpiece part (16) of the grass collection container (8) on top, cover the upper part of the grass collection container (8) with a cover (17), this cover A grass collection mechanism is configured by connecting a duct (9) for transporting grass clippings to (17).

Inside the cover (17), an inverted U-shaped stopper (a U-shaped stopper) as a restricting member for preventing relative lateral movement of the central pedestal (15) and the mouthpiece (16) when the cover (17) is set ( 18),
The cover (17) is located near the tip of the central pedestal (15) via a positioning member (19) that determines the set position of the cover (17).
Is attached to. At the tip of the center cradle (15), a stopper rubber (20) is planted upward at a position where it does not interfere with the mouthpiece part (16) of the grass container (8), and the positioning of the cover (17) The member (19) contacts the rubber (20) so that the cover (17) can be positioned in the set state.

Further, as shown in FIG. 4, a locking member having a bifurcated front end, which is rotatable about a pivotal fulcrum (P ₁ ) of the horizontal shaft, at the lower end of the central cradle (15). With (21),
An opening / closing hook (23) that engages with the forked portion of the locking member (21)
Is provided on the inner surface of the cover (17), and the cover (17) is attached to the support frame (4) around the pivot portion provided on the front side by engaging / disengaging the locking member (21) and the opening / closing hook (23). It is constructed so that it can be rotated and opened and closed.

The opening / closing hook (23) is formed by fitting a hook bar (26) biased upward by a spring (25) into a stay (24) which is a member on the cover (17) side.
(26) By engaging the flange (27) at the lower end with the forked portion of the locking member (21), the cover (17) is fixed while being urged downward. It is preferable to interpose a cushion (28) between the locking member (21) and the lower surface of the central pedestal (15).

Inside the upper side of the outer cradle (14), the base of the grass container
A round bar (29) is attached to prevent the (16) from coming inward, and the grass container (8) supports the supporting arm (14) by the round bar (29) and the above-mentioned stopper (18). It is designed to prevent it from coming off from (15).

[Another embodiment]

As shown in FIG. 6, the base part (1
The cover (17) is used as a means to restrict the lateral movement of
You may employ | adopt the stopper member (18) which is a regulation member provided inside. Support arms (14), (15) and mouthpiece (16) in this case
All lateral movements relative to the control member are provided on the cover (17) side.
It will be prevented in (18).
