Collected in a box. In this case, by providing the guide plate, the empty space 1111 created can be used to secure the capacity of the grass collection box, and the height of the grass collection box can be increased to increase the capacity of the grass collection box. It is possible to improve the grass collection ability of the grass collection device and reduce the frequency of throwing away grass clippings. Furthermore, since the grass collecting box is of a closed type, it is possible to reliably collect the grass clippings without scattering them around.

Furthermore, if a large outlet is formed on the underside of the grass collecting box, collecting grass can be
The grass clippings collected in the box can be disposed of easily and quickly.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a side sectional view of a lawn mower equipped with a grass collecting device according to the present invention, and FIG. 2 is a perspective view of a grass collecting box.

The lawnmower l shown in Fig. 1 is a hand-held type, and its main body 2 has a handle 3 for operation that stands up diagonally backwards, and a mesh screen at the rear of the main body 2 that does not allow cut grass to pass through. A shaped grass collection box 4 is detachably attached.

Further, the main body 2 is supported by two left and right wheels 5, 5 and one tail wheel 6 so as to be freely movable, and a reel blade 7 which is rotatably driven in the direction of the arrow in the figure is arranged at the bottom of the main body 2. A lower blade 8 is attached below the reel blade 7 with a slight gap between the lower blade 8 and the reel blade 7.

Furthermore, above the reel blade 7 inside the main body 2.

A drive system for rotationally driving the reel blade 7 is housed, and this drive system includes an engine 9, an air cleaner lO,
Mixer 11, gas cylinder 12. Regulator 13.
A V-belt 17 is wound between a pulley 15 connected to the output shaft end of the transmission 14 and a pulley 16 connected to the rotating ring of the reel blade 7. . The engine 9 in this embodiment is a gas engine that operates using gas filled in a gas cylinder 12 as fuel.

By the way, from the rear of the sole blade 7 in the lawn mower main body 2, a guide plate 18 extends obliquely upward toward the rear, and the upper end of the guide plate 18 curves backward in an arc. It is continuous with a rectangular suction port 19 that opens at the top of the grass collecting box 4. Thus, at the rear of the lawnmower main body 2, a guide plate 18 defines a weeding path 20 for guiding the cut grass to the grass collecting box 4.

On the other hand, the grass collection box 4 is set at a height approximately concave to the height of the lawn mower body 2, and has a large rectangular discharge port 2 on its bottom surface.
1 is open, and the outlet 21 is opened and closed with a lid 22 that can be opened and closed, or a Velcro tape 23 is attached to the lid 22, and a similar magic tape is attached to the main body side of the grass collecting box 4. Tape 24 is attached. In addition, the discharge port 21
422, the Velcro tape 23 attached to the lid 22 is adhered to the Velcro tape 24 on the main body side of the grass collection box 4 to keep the lid 22 closed.

Then, while driving the engine 9, the operator or the handlebar 3
When the lawn mower l is pushed forward while pushing the lawn mower l, the grass is cut by the reel blade 7 rotating in the direction of the arrow in FIG. 1 and the fixed lower blade 8, and the cut grass is guided by the guide plate 18. The weeds are sent along the weeding path 20 in the direction of the arrow in FIG.

In this case, since the grass collection box 4 is of a closed type, the grass clippings are surely collected in the grass collection box 4 without scattering to the surroundings. Furthermore, by providing the guide plate 18, the space created at the rear and lower part of the lawn mower main body 2 can be used to secure the capacity of the grass collection box 4, and the height of the grass collection box 4 can be adjusted to the height position of the lawn mower main body 2. Since the capacity of the grass collection box 4 can be increased by increasing the capacity of the grass collection box 4, the grass collection capacity of the grass collection device can be increased, thereby reducing the frequency of throwing away grass clippings and reducing the burden on the operator. I can do it.

By the way, when the grass collection box 4 is full of grass clippings, remove the grass collection box 4 from the lawn mower body 2 and carry it to a predetermined location, and carry out one test to see if it is necessary to throw away the grass clippings. In the example, if you peel off the Velcro 23 and open 422,
Since a large discharge port 21 is opened on the lower surface of the grass collecting box 4, the cut grass can be disposed of easily and quickly with good work efficiency.

In the above embodiments, the present invention has been specifically applied to a hand-held lawn mower, but it goes without saying that the present invention can be applied to any other type of lawn mower. .
