Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grass-collecting device for a mower, which is capable of cutting grass with a mower and collecting the cut grass in a grass container.

[0002]

2. Description of the Related Art Conventionally, for lawn mowing on a golf course,
A mower equipped with a mower and a grass container, and a feeding duct that feeds the grass and dust cut by the mower into the grass container by feeding it on the air stream is used. For example, Japanese Utility Model Publication No. 5-6737 and Japanese Utility Model Publication 3-3.
There is one disclosed in Japanese Patent No. 8996.

Regarding the grass collection container, when a large amount of grass is collected in one large grass collection container, the weight of the grass collection container increases, and the grass collection container is discarded when it is discarded. Since it is difficult to handle the container, it has been practiced to mount two small grass collection containers close to each other as disclosed in Japanese Utility Model Publication No. 5-6737.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a mowing machine equipped with two grass collecting containers as disclosed in Japanese Utility Model Publication No. 5-6737, the mowing grass is evenly distributed in each grass collecting container and is the same. In order to improve work efficiency, it is necessary to fill the grass at the timing and dispose of the mowing grass in each grass container at the same time. However, it is difficult to evenly distribute the grass clippings in each of the grass collection containers so that the timings at which the grass collection containers fill up coincide with each other, and the timing at which each grass collection container fills varies. Therefore, when one of the grass collection containers becomes full, the grass clippings in the grass collection container are discarded, and the grass cutting operation is frequently interrupted in order to dispose of the collected grass grass. Work efficiency is decreasing.

Particularly, when the place where the grass is disposed of is distant from the work site, it takes time to make a round trip between the place where the waste is disposed and the work site, and the efficiency of the mowing work is significantly reduced. .

Even in a mowing machine equipped with one grass collecting container, if the discharge direction of the mowing grass is not dispersed, the mowing grass will be gathered in a state in which it is biased to only one side in the grass collecting container, and the grass is regularly gathered. It is necessary to discontinue the mowing work and flatten the grass that has been gathered in an uneven state, which takes time and reduces the efficiency of the mowing work.

[0007]

The invention according to claim 1 is
A mower and a grass container are attached to a traveling vehicle body, and a feeding duct for feeding grass and dust cut by the mower into the grass container by feeding the grass and dust into the grass container and the mower and the grass container. In the mowing machine arranged between the two, the cyclone-type separation device which opens one end of the feeding duct at a position above the grass collection container and separates the cut grass and dust fed to one end of the feeding duct from the air. The cyclone-type separator for discharging the separated grass and dust into the grass container was equipped with a dispersion for dispersing the direction of discharge of the grass and dust.

According to a second aspect of the invention, in the first aspect of the invention, the dispersion is attached so that the position of the dispersion is adjustable.

[0009]

According to the first aspect of the present invention, the grass and dust fed in the feeding duct reach the cyclone separator, and are separated from the air in the cyclone separator and discharged into the grass container. Then, since the discharge direction of cutting grass and dust is dispersed by the dispersion body, when two grass collecting containers are attached, the grass is evenly collected in each grass collecting container.
When one grass collection container is attached, it is prevented from shifting to one side.

According to the second aspect of the invention, the discharge direction from the cut grass discharge port of the cyclone separator changes depending on the type and amount of cut grass, the wetness of the cut grass, and the like. By adjusting the mounting position, grass and dust are discharged in a dispersed state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. First, in FIG. 1, a mower 2 and a pair of left and right grass-collecting bags 3 which are grass-collecting containers are attached to a traveling vehicle body 1. Further, the grass and dust collected by the mower 2 are placed on the air flow to collect the grass. 3 is a side view showing the overall structure of a mower in which a feeding duct 4 for feeding the inside of the mower 3 is arranged between the mower 2 and the grass bag 3, FIG. 2 is its plan view, and FIG. 3 is its rear surface. It is a figure.

The mower 2 is attached to the lower abdomen between the front wheels 5 and the rear wheels 6 of the traveling vehicle body 1. The mower 2 has three cutting blades 7 for cutting grass such as grass. Is rotatably provided, and a blower 8 for generating a flow of air for feeding the grass cut by the mower 2 through the feeding duct 4 is attached. In addition, these cutting blades 7
The power transmission to the blower 8 and the blower 8 is performed from an engine (not shown) of the traveling vehicle body 1 via a mower drive shaft 9 and the like.

Next, the mounting structure of the grass bag 3 will be described. A pair of left and right side plates 10a is provided at the rear of the traveling vehicle body 1.
The exterior case 10 formed by the front plate 10b and the upper plate 10c is attached. The left and right side plates 10a have a pair of support bars 11 and 12 extending inward.
Is fixed, and a plurality of grass collecting bags 3 each having four eyelet holes 13 are supported by these support rods 11 and 12 in a folded state. In addition, the front plate 10
A central support bar 14 extending rearward at the center of the left-right direction of b.
The central support rod 14 is provided with a fixed type support protrusion 15 and a support protrusion 17 rotatable in the front-rear direction about a pin 16 as a fulcrum. The support protrusion 17 is moved backward by a spring 18. It is biased to rotate.
The pair of innermost grass collection bags 3 supported by the support rods 11 and 12 has the pair of insertion holes 13 locked to the support rods 11 and 12. And the other pair of dowel holes 13 are supported by the supporting projections 15, 1
As shown in FIG. 4, it is mounted in a state capable of collecting grass by being locked to 7. A pair of trays 19 for supporting the bottom of the grass bag 3 mounted in a grass-grassable state are attached to the lower end of the front plate 10b.

Next, a cyclone type separator 20 for separating the grass and dust fed in the feeding duct 4 from the air is attached to the upper surface plate 10c, and the cyclone type separator 20 is attached. One end of the feeding duct 4 is connected to the upper part of the. The cyclone separator 20 is provided with a cut grass discharge port 21 for discharging the separated cut grass and dust into the grass bag 3, and the cut grass discharge port 21 collects the cut grass and dust. A dispersion ring 22 that is a dispersion that disperses the discharge direction is attached. The dispersion ring 22 is formed by rolling a flat plate into a ring shape, and the cutout 2 is partially formed.
3 is formed, and the dispersion ring 22 is rotatably attached so that the cutout 23 can be oriented in any direction. A space 24 having a predetermined size is provided between the lower end of the dispersion ring 22 and the upper end of the grass bag 3.

In such a structure, when the mower is run while driving the mower 2 and the blower 8 in the work ground (eg, golf course), the mower 2 cuts grass such as grass and is cut by the mower 2. The cut grass and dust existing around the cut grass are carried by the flow of air generated by the blower 8 toward the grass bag 3 in the feeding duct 4.

The grass and dust fed in the feeding duct 4 are discharged into the cyclone separator 20 from one end of the feeding duct 4, and the grass and dust discharged in the cyclone separator 20 are cyclone type. It falls while rotating in the separator 20. And in the process of falling while turning,
The grass and dust are moved to the outer peripheral side of the cyclone separator 20 by the action of the centrifugal force, and the air from which the grass and dust are separated is a cylindrical air outlet 25 provided in the center of the cyclone separator 20. Emitted into the atmosphere.
On the other hand, cut grass and dust are discharged from the cut grass discharge port 21 and collected in the grass collecting bag 3.

Therefore, during the mowing work by this mowing machine, the air containing dust is not discharged to the atmosphere and blows up the dust, and the mowing work is performed under a good working environment in which the dust does not fly up. Can be done.
Moreover, since the flow of the air generated by the blower 8 is sufficiently strong at one end of the feeding duct 4 to which the cyclone separator 20 is connected, the cutting grass and dust are separated well from the air.

Next, the cyclone separator 20 will be in a state in which grass and dust fall directly below if a sufficient height dimension is secured, but from the viewpoint of securing a large grass gathering space and two In order to disperse the grass into the grass bag 3 and discharge it obliquely downward, the height of the conical portion of the cyclone separator 20 is set to be small and discharged from the cut grass discharge port 21. Cut grass and dust are discharged diagonally downward. More specifically, the height dimension of the conical portion of the cyclone separator 20 is set so that the grass and dust discharged from the grass outlet 21 are discharged to a range equal to or larger than the outer diameter dimension of the cyclone separator 20. Has been done.

A part of the cut grass or dust discharged from the cut grass discharge port 21 collides with the inner peripheral surface of the dispersion ring 22 and is cut out.
Bounces to the 3 side, and part of the grass and dust is discharged as it is without colliding with the inner peripheral surface of the dispersion ring 22, so the direction of discharge of the grass and dust is not one direction and is dispersed in various directions. It Therefore, the grass and dust are evenly collected in the two grass bags 3, and the two grass bags 3 are
Fills up at about the same time. When the grass collection bag 3 is full, the eyelet holes 13 of the grass collection bag 3 are removed from the support rods 11 and 12 and the support projections 15 and 17 and provided in the opening of the grass collection bag 3. The fasteners (not shown) are closed, and the grass bag 3 is removed from the mower, and the new grass bag 3 is put in a mountable state.
Since you can attach and detach the two grass bags 3 at the same time,
The frequency of interrupting the mowing work for attaching and detaching the grass collecting bag 3 is reduced, and the work efficiency of the mowing work is improved. In addition, the grass collection bag 3 left from the mower and left in the work area is collected by running a dedicated collection vehicle later.

Here, the discharge direction from the cut grass discharge port 21 of the cyclone separator 20 changes depending on the kind and amount of cut grass, the wetness of the cut grass, etc. In that case,
In accordance with the change, the distribution ring 22 is rotated to move the cutout 2
By adjusting the position of 3, the grass and dust are evenly distributed and discharged into the two grass bags 3.

In the present embodiment, the case where the mowing machine is used for mowing work has been described as an example, but the mowing machine can also be used for collecting fallen leaves.

[0022]

As described above, according to the first aspect of the present invention, one end of the feeding duct disposed between the mower and the grass container is opened at a position above the grass container and the feeding duct is provided. A cyclone separator that separates the cut grass and dust fed from the air was installed at one end of the, and a dispersion that disperses the discharge direction of the cut grass and dust was installed at the cut grass outlet of this cyclone separator. The direction of discharge of cut grass and dust discharged from the cut grass discharge port of the separator can be dispersed by the dispersion body. Therefore, when two grass collection containers are installed, The grass can be evenly collected and the timing when each grass container is filled can be matched. Therefore, the grass cutting can be carried out by simultaneously disposing of the collected grass in the two grass containers. Of work It is possible to improve the business efficiency and prevent the grass to be collected from being collected on only one side in the grass container when one grass container is installed. Therefore, the work efficiency of the mowing work can be improved by omitting the work of flattening the cut grass collected on only one side.

According to the second aspect of the present invention, as described above, in the first aspect of the present invention, the dispersion is attached so that the position can be adjusted. Therefore, the cyclone type can be selected depending on the type and amount of the grass and the wetness of the grass. When the direction of discharge of the grass or dust discharged from the grass cut outlet of the separator changes, the mounting position of the dispersion can be adjusted according to the change, and therefore the cut grass discharged from the grass cut outlet can be adjusted. It has the effect that dust and dirt can always be discharged in a dispersed state.
