Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grass collection container support structure for a lawn mower, which has a fixed frame for mounting and supporting the caps of two adjacent grass collection containers.

[Conventional technology]

In the grass collection container support structure of this type of lawn mower,
Conventionally, the fixed frame has been constructed by integrating two circular-section pipe frames on which the caps of two grass collection containers are individually placed and supported, with the adjacent side frame portions of each frame closely attached. Ta.

[Problem that the invention attempts to solve]

In this case, a recessed space surrounded by both circular pipes is formed above the joint between adjacent side frame parts of the pipe frame, and grass clippings and grass debris tend to accumulate in this recessed space. Even if this grass clippings were to be removed, it could not be removed by simple methods such as sweeping it away by hand, as it had entered the recessed space. Therefore, if the grass clippings tend to be removed and the grass clippings continue to accumulate in the recessed space, the collected grass will overflow to the top of the circular pipe frame, and the grass clipping container side cap will be closed. was not placed in the designated position on the pipe frame or was placed on the cut grass, and in either case the grass collection container was not attached in a stable state.

The purpose of this invention is to make it easier to remove grass clippings by adding simple shape deformation to the fixed frame that supports the adjacent sides of the caps of both grass collection containers.
Another object of the present invention is to provide a fixed frame that can stably support a grass collection container.

[Means for solving problems]

The characteristic configuration of the present invention is that a single central frame is provided to support the sides of two adjacent caps when two grass collection containers are placed adjacent to each other on a fixed frame; an outer frame is provided to support the cap other than the base; the single central frame and the outer frame form a fixed frame; is formed on a flat surface, and the functions and effects are as follows.

[Effect]

As shown in the characteristic configuration, the single central frame is wide enough to support the sides of two adjacent caps and is flat over its entire surface. Even if grass clippings accumulate on the top surface, they can be easily removed by simply brushing them off by hand.

[Effect of idea]

Therefore, the work of removing grass clippings can be done easily without the need for special cleaning tools, and
Since the sides of the cap can always be placed on a flat surface, a stable support state can be maintained. Furthermore, since the center frame is wide, even if there is some dimensional error between the cap of the grass collection container, the outer frame on the fixed frame side, and the center frame, the cap can be moved from the outer frame to the center frame. It also has the effect of being able to be placed in a predetermined state where it is placed in contact with the entire surface.

〔Example〕

As shown in FIG. 6, the riding lawn mower is equipped with a downward output shaft engine 1 at the front of the machine, a transmission case 2 at the rear of the machine, a driving operation section 3 between them, and front and rear wheels 5, 6. In between, there is provided a mid-mounted mower 7 and an external grass collection duct 9 that guides the grass clippings from the mower 7 to a grass collection container 8 connected to the rear end of the machine.

Next, the mounting structure of the grass collecting container 8 will be explained. 1st
As shown in the figures or FIG. 4, a main frame 11 has a support frame 10 made of a pipe that can be inserted into the rear opening ends 11A of the left and right main frames constituting the aircraft body.
An engagement pin 1 passing through both while connected to the
2, the fixed frame 13 is connected and fixed to the raised upper opening end 10A of the support frame 10 for mounting and supporting a pair of left and right grass collecting containers 8, 8 to be described later. has been done. In this connection and fixing structure, a pair of left and right pipe engaging portions 13a projecting downward from the fixed frame 13 are fitted into the upper open end 10A of the frame 10. This fixed frame 13 is formed into a substantially E-shape in plan view by an outer frame 13A made of a circular pipe frame that is U-shaped in plan view and a channel frame 13B as a central frame, and extends rearward in a cantilevered manner. . With respect to this fixed frame 13, a cap 8A provided at the upper end opening periphery of the upwardly opening grass collection container 8
is pipe frame 13A and channel frame 1
The grass collecting container 8 is set so as to be placed in contact with the container 3B over the entire length thereof from above. The upper surface 13C of the channel frame 13B, which supports the adjacent mouth side portions 8a, 8a of the two grass collection containers 8, 8, is wide and flat on its entire surface. A plate-like member 14 having an engaging hole 14a formed therein protrudes from the base 8A of the grass collecting container 8, and a protruding piece 14 is provided on the pipe frame 13A portion of the fixed frame 13.
3b is provided protrudingly, and the grass collection container 8 is attached to the fixed frame 13.
When placed on the grass container 8, the protruding piece 13b passes through the engagement hole 14a, and the position of the grass collecting container 8 is regulated.

Next, the opening/closing cover 15 for the left and right grass collecting containers 8, 8 will be explained. A pair of left and right brackets 1 are provided with horizontal engagement holes 16a in the lower flange portion 15A of the opening/closing cover 15 on the side of the support frame 10.
6 and 16 are fastened and fixed, and a plate piece 17 on which a headed pin 17a is fixed and protruded sideways is provided on the support frame 10, and the pin 17
By fitting and fixing a into the engagement hole 16a, the opening/closing cover 15 can swing up and down around the pin 17a. By placing the opening/closing cover 15 on the fixed frame 13 or the grass collection container 8 fitting and sliding it laterally, the pin 17a is fitted into the engagement hole 16a, and the opening/closing cover 15 is attached. A simple installation method can be used. On the other hand, a hook 18 is provided at the lower end of the opening/closing cover 15 opposite to the side where the bracket 16 is present, and a stopper 19 whose one end is fixed to the channel frame 13B on the fixed frame 13 side is latched to the hook 18. , is configured to maintain the closed position of the open/close cover 15.
The opening/closing cover 15 covers the upper space of the grass collecting containers 8, 8 in a communicating state, and the air exhaust passage A communicates from the upper space to the rear space in the internal space.
A net-like body 20 is stretched to form a net-like body 20, and air is exhausted from this net-like body 20 when the grass clippings are full or when a garbage storage bag with poor ventilation is used in the grass collecting container 8.
The opening/closing cover 15 is configured to exhaust air from an opening B at the lower end along the inner surface of the openable cover 15. however,
If the garbage storage bag is not used, the air will be exhausted from the grass collection bag.
