Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a riding mower that cuts grass such as lawn with a mower and collects it in a grass collecting container.

<Prior art> Riding mowers, which are equipped with a mower between the front and rear wheels at the lower part of the vehicle body and which collects grass cut by the mower through a duct into a grass collection container, have already existed, and are used for lawn mowing work. etc. is used.

In this type of riding mower, the grass collection container has conventionally been installed at the rear of the vehicle body or on one side of the rear, and it is not originally installed on the vehicle body itself, but is installed separately. Most of them were.

<Problems to be Solved by the Invention> When such a grass collection container is separately installed at the rear of the vehicle body, an additional mounting mechanism must be provided for this purpose, and the grass collection container is placed far behind the rear wheels. Because it protrudes, the overall length in the front and rear direction increases,
When equipped with a grass collection container, it had the disadvantage of becoming extremely large. In addition, the weight of the grass collection container varies greatly depending on the amount of grass cut inside, so it is difficult to balance the weight between the front and rear of the vehicle body due to its design, which is dangerous when working on slopes or the like.

On the other hand, when the grass collection container is installed on one side of the rear of the vehicle, the grass collection container protrudes to the side, making it difficult to work near obstacles, and when the yield of grass clippings increases, there is a risk of rollover, etc. There were also problems and capacity was limited.

The present invention provides a riding mower that can solve these conventional problems.

<Means for Solving the Problems> As a means for solving the above-mentioned problems, the present invention provides a mower 9 between the front and rear wheels 2 and 3 in the lower abdomen of the vehicle body 1, and a A grass collection container 2 that collects cut grass through a duct 17

Next, the operation of the above configuration will be explained. When mowing a lawn or the like, the mower 9 is placed on the ground, and the cutter blade 12 is rotated around the vertical axis 11 while running. When the cutter blade 12 rotates, it cuts the grass, etc., and the cut grass is collected toward the passage 16 side by the wind generated by the wind raising part 15, and the duct 17 along with the airflow. , and is fed into the grass collection container 20 via the chute 19. On the other hand, the air sent into the grass collection container 20 is removed by a screen 27 and then exhausted to the outside through an air outlet 28.
Therefore, only the grass clippings accumulate in the grass collection container 20 and can be collected following mowing. In this case, since the chute 19 is inserted into the grass collecting container 20 through the hole 30 formed in the bottom 29 of the grass collecting container 20, the chute 19 is inserted into the grass collecting container 20. The space above 1 can be used effectively,
Therefore, a sufficient volume of the grass collecting container 20 can be secured.

As the amount of grass clippings in the grass collection container 20 increases, the weight on the grass collection container 20 side increases accordingly, but the grass collection container 2
0 is located on the front axle 4, the front and rear weight balance of the vehicle body 1 does not change greatly during work due to an increase in the amount of grass clippings, and it is possible to prevent overturning even when working on a slope.

When the grass collection container 20 is filled with grass clippings, the grass is discharged from the grass discharge port 21 on the front side.
After releasing the locking tools 25 and 26, the grass collection container 20
It is sufficient to lift the rear side of the holder and tilt it around the horizontal axis 24 as shown by the imaginary line in FIG. At this time, the chute 19 is on the vehicle body 1 side, but since the chute 19 has an arc shape, the grass collection container 20 can be easily rotated, the opening of the hole 30 can be minimized, and the chute 19 can be made high enough. Grass collection container 20
If the front cover 23 is made to have an inclined shape, the grass clippings will slide down along the slope of the bottom portion 29 while pushing the front cover 23 open, so that the grass clippings can be easily removed.

In addition, if the chute 19 is attached to the vehicle body 1 as in the above embodiment, the chute 19 and the grass collecting container 2 can be connected to each other.
Although relative positioning with respect to 0 can be easily performed, a flexible duct 17 is required.

It can be used satisfactorily with a fit of 9. Therefore, more 9
The connection between the grass collection container 20 and the grass collecting container 20 is also facilitated.

Furthermore, if the rear wall of the grass collecting container 20 is entirely or partly made up of a transparent plate, the amount of grass clipped in the grass collecting container 20 can be determined even while the operator on the seat 39 side is driving.

In addition, the grass collecting container 20 has hydraulic cylinders 43 installed on both left and right sides or one side as shown by the imaginary line in FIG.
Alternatively, a blower 44 may be provided in the middle of the duct 17.

<Effects of the Invention> According to the present invention, since the grass collection container is provided on the vehicle body, there is no need to provide an additional mounting mechanism such as a separate equipment, and therefore, the grass collection container is provided on the vehicle body. Despite this, the entire structure can be made smaller. In addition, since the grass collection container is installed on the vehicle body on the front axle, the weight balance between the front and rear is not significantly affected by the amount of grass clippings in the grass collection container, which prevents falls on slopes and allows for safer work. is possible. Furthermore, work near obstacles can be easily performed. In addition, since the grass collection container can be raised backwards around the horizontal axis, weeds can be easily removed from the weed outlet on the front side. Moreover, since the chute can be inserted into and removed from the hole in the bottom plate and is inserted into the grass collecting container through the hole, the space on the vehicle body can be effectively utilized and a sufficient volume of the grass collecting container can be secured.
In addition, since the upper side of the chute is formed in an arc shape centered on the horizontal axis, there is no need to remove the chute even though the grass collection container can be rotated when weeding.
