Description

Description: TECHNICAL FIELD The present invention relates to a grass collection structure for a lawn mower, which is mounted on a grass collection container and provided with an opening / closing cover for covering the container opening.

[Conventional technology]

An example of the grass collection structure of this type of lawn mower is,
-98429 gazette, a fixed frame for supporting a grass container is coupled and connected from above to a support frame erected at the rear end of the machine body, and the grass container is mounted and supported on the fixed frame. An opening / closing cover for covering the upper opening of the is pivotally supported by a bracket fixed to the fixed frame so as to swing, and a reinforcing brace is installed between the rear end of the fixed frame and the bracket on the body side. It is known that a stopper is attached to the free end of the opening / closing cover.

[Problems to be solved by the invention]

However, in the above conventional structure, since the fixed frame supporting the open / close cover is fitted and connected to the support frame of the machine body, the grass container and the open / close cover can be opened if the machine shakes greatly. The fixed frame may be pulled out of the support frame while it is supported, and the brace is installed over the rear end of the fixed frame and the bracket on the machine side to prevent the fixed frame from pulling out of the support frame. .

That is, in this conventional configuration, in order to prevent the fixed frame from being pulled out from the support frame, it is essential to install the brace between the rear end of the fixed frame and the bracket on the body side. .

As a result, not only is the number of components increased, making the structure complicated, but when the grass collection structure is removed from the machine and stored, the brace becomes a bulky member, and it is necessary to disassemble the brace, making handling easier. Had lowered.

The present invention has been made paying attention to such a point, and while simplifying the structure by reducing the number of constituent members,
An object of the present invention is to enable traveling work without fear that the fixed frame and the grass collection container will come off in a state where the grass collection structure is attached to the machine body, and moreover, to allow the grass collection structure removed from the machine body to be stored in a compact and bulky manner.

[Means for solving problems]

The characteristic configuration according to the present invention is that a fixed frame for supporting a grass container is engaged and connected to the upper end of a support frame attached to the body from above, and an upper opening portion of the grass container is engaged to this fixed frame from above. A point for constructing a support, a point for swingably pivoting an opening cover for covering the upper opening of the grass container supported by a fixed frame on a bracket fixed to the support frame, and a free end of the opening / closing cover. A stopper for restricting the upward movement of the opening / closing cover is mounted over the portion and the fixed frame, and the action and effect thereof are as follows.

[Work]

In other words, when the open / close cover is closed and the stopper is attached, one end of the open / close cover is pivotally supported by the support frame and
Since the other end is supported by the fixed frame with a stopper, the upper opening of the grass container is sandwiched between the open / close cover and the fixed frame, and the grass container floats up and comes off the fixed frame. Is certainly prevented.

(B) Since the balance point of the open / close cover is installed on the support frame on the machine side, the fixed frame can move upward with respect to the support frame by stopping the open / close of the open / close cover by connecting the open / close cover to the fixed frame with a stopper. Disappear.

C When you remove the stopper and swing the open / close cover upward,
The pressing action on the fixed frame is released, and the fixed frame can be immediately pulled out upward from the support frame.

〔The invention's effect〕

Therefore, according to the present invention, the following effects can be expected.

That is, it is possible to prevent the fixed frame from coming out of the support frame without using a separate component such as a brace by reasonably setting the attachment position of the opening / closing cover and the attachment position of the stopper, which saves members. It is possible to simplify the structure.

Also, when removing the grass collection structure from the aircraft and storing it,
There is no need to disassemble the brace or the like, and it can be easily stored in a low bulk.

〔Example〕

As shown in Fig. 6, the riding lawn mower has a downward output shaft engine (1) at the front of the machine and a mission case at the rear of the machine.
(2), equipped with a driving operation unit (3) between them, mid-mount mower (7) between front and rear wheels (5), (6), lawn mowing from this mower (7) at the rear end of the aircraft It is constructed by providing an externally-operated grass-collecting duct (9) that guides the grass-collecting containers (8) arranged in series.

Next, the mounting structure of the grass container (8) will be described. As shown in FIGS. 1 to 4, a pipe-made support frame (10) as a connecting member that can be inserted into the rear open ends (11A) of the left and right main frames constituting the airframe is attached to the main frame (11). In the connected state, the engaging pin (12) as a fixing means penetrating the both is configured to be detachable, and to the rising upper opening end (10A) of this support frame (10),
A fixed frame (13) for mounting and supporting a pair of left and right grass collecting containers (8), (8) described later is connected and fixed. In this connecting and fixing structure, a pair of left and right pipe engaging portions (13a) protruding downward from the fixing frame (13) are provided at the upper opening end (1) of the frame (10).
0A). This fixed frame (13) is formed in a substantially E shape in a plan view by a U-shaped pipe frame (13A) in a plan view and a channel frame (13B) in the center, and extends in a cantilever shape toward the rear. . With respect to this fixed frame (13), the mouthpiece (8A) provided on the upper edge of the upward opening grass container (8) is provided over the entire length of the pipe frame (13A) and the channel frame (13B). The grass container (8) is set so that it is placed on and touched with. The base of this grass container (8)
A plate-like member (14) having an engaging hole (14a) is projected from (8A), and a pipe frame of the fixed frame (13).
When the projecting piece (13b) is projected on the (13A) part and the grass container (8) is placed on the fixed frame (13), the projecting piece (13b) is engaged with the engaging hole (14).
The position of the grass container (8) is restricted by being penetrated by a).

Next, as shown in FIGS. 1 and 4, left and right grass collection containers
The opening / closing cover (15) for (8) and (8) will be described. The lower surface flange portion (1) of the opening / closing cover (15) on the support frame (10) side.
A pair of left and right brackets (16) and (16) having lateral engagement holes (16a) formed in (5A) are fixed and fixed, and a head pin (17a) is laterally attached to the support frame (10). A plate piece (17) as a fixedly protruding bracket is projected, and the opening / closing cover (15) is fixed to the pin (17a) by fitting and fixing the pin (17a) in the engagement hole (16a). It can swing up and down around it. Attach the open / close cover (15) to the fixed frame (13).
