Abstract

PURPOSE:To provide a lawn mower giving a beautifully mowed lawn by pushing the cut lawn grass into the lawn on the ground with a pushing rotor according to the movement of the machine body, thereby hiding the cut grass with the grown lawn and preventing the blow-off of the grass by the wind. CONSTITUTION:The objective walking-type or riding-type lawn mower has a pair of right and left front wheels 2 in front of the mower 1, a pair of right and left rear wheels 3 and an operation handle 4 at the back of the mower 1, an engine 5 above the mower 1 and a cutting blade 6 rotating around a vertical shaft P1 in the mower 1. A pair of right and left arms 8 are supported around the shaft 3 of the rear wheels 3 in a vertically movable state and a pushing rotor 7 composed of plural sets of pushing disks 10 and cylindrical spacers 11 extending over the whole length of the supporting arm 8 is supported by a shaft 9. The pushing rotor 7 placed at the back of the mower 1 pushes the cut lawn grass into the lawn A on the ground according to the movement of the machine body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn mower of a walking type or a riding type, and to a structure for treating grass.

[0002]

2. Description of the Related Art In a walking or riding lawn mower,
There is a type in which the grass cut by the mower is left on the grass on the ground without being collected in a grass container or the like.

[0003]

In a lawnmower of the type described above, since the lawnmower remains on the lawn on the ground after the lawn mowing work, the lawnmower is blown away especially when a strong wind blows. There is. In addition, if the cut grass remains on the grass on the ground, the cut marks may be unsightly. It is an object of the present invention to provide a lawnmower of a type that does not collect turf so that the turf is not blown off by a strong wind and the cut mark is not unsightly.

[0004]

The feature of the present invention resides in that the lawnmower of the type that does not collect grass as described above is configured as follows. That is, a push-in rotating body that pushes the cut grass into the grass on the ground by rotation as the aircraft advances is provided on the rear side of the mower.

[0005]

When the pushing rotary body as described above is arranged on the rear side of the mower, the grass cut by the mower and placed on the grass on the ground is sequentially pushed into the grass on the ground by the pushing rotary body. Go. If the cut grass is pushed into the grass on the ground in this manner, the cut grass is held in the grass on the ground, and the cut grass is not blown away by the wind. Then, since the cut grass is hidden in the grass on the ground, the cut marks are not unsightly.

[0006]

EFFECT OF THE INVENTION By equipping the pushing rotary member as described above, since the lawn is hidden in the lawn on the ground without being blown away by the wind, it is possible to collect the blown lawn. You can get a beautiful finish without the need for extra work.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, a cutting blade housing 1 (corresponding to a mower) is provided with a pair of left and right front wheels 2, a rear portion is provided with a pair of left and right rear wheels 3 and a steering handle 4, and an engine is provided above the cutting blade housing 1. A walk-behind lawnmower is provided with the number 5. In the cutting blade housing 1, there is provided a cutting blade 6 which is driven to rotate around a vertical axis P1.

Next, the pushing rotary member 7 arranged on the rear side of the cutting blade housing 1 will be described. As shown in FIGS. 1, 2, and 3, a pair of left and right support arms 8 are supported around the axle core P3 of the rear wheel 3 so as to be freely swingable up and down. The pushing rotary body extends across the left and right support arms 8. 7 are supported.
The pushing rotary body 7 is configured by alternately mounting a plurality of disc-shaped pushing plates 10 and cylindrical spacers 11 on a support shaft 9, and the pushing plates 10 and the spacers are arranged around the axis P2 of the support shaft 9. 11 is configured to rotate freely.

With the above construction, when the lawnmower is moved to the left side of the plane of FIG. Rotate counterclockwise. Therefore, the lawn grass is pushed into the lawn A on the ground by the rotating pushing plates 10 and the spacers 11.

Depending on the condition of the lawn A or the like, the spacer 11 of the pressing rotary member 7 is replaced with one having a different length to change the lateral arrangement pitch of the pressing plates 10 or the pressing plates 10 having different outer diameters. It is exchanged for.

[Other Embodiment] Although the pushing plate 10 in the above-mentioned embodiment is disk-shaped, a plurality of sets of arms may be radially arranged to form the pushing plate 10. Alternatively, the pushing rotor 7 may be configured to be forcedly driven by the power of the engine 5 instead of being freely rotated. The push-rotating body 7 which is freely rotated or driven and driven may be arranged obliquely with respect to the lateral direction of the machine body, instead of being parallel to the lateral direction of the machine body. Then, the pushing rotary body 7 of the present invention may be provided to a riding type lawnmower in which a mower is arranged on the front side of the front wheels or between the front wheels and the rear wheels.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
