Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a riding mower that cuts grass such as lawns with a mower attached to a vehicle body and collects the grass in a grass collecting container.

(Prior art) Riding mowers have already existed in the past, which are equipped with a mower between the front and rear wheels in the lower abdomen of the vehicle body, and collect grass cut by the mower through a duct into a grass collecting container. It is used for work etc.

In this type of riding mower, the grass collection container has traditionally been installed at the rear of the vehicle body, and in most cases it is not originally installed on the vehicle body itself, but is an additional device. It was hot.

Furthermore, in the past, a part or all of the wall of the grass collection container was made of punched metal, a net, or the like, so that the air fed together with the grass clippings could be exhausted to the outside.

(Problem to be solved by the invention) In the case where the grass collection container is installed at the rear of the vehicle body, the grass collection container protrudes significantly rearward from the rear wheels, so the overall length in the longitudinal direction becomes large. However, when equipped with a grass collection container, it had the disadvantage of becoming extremely large. In addition, unsorted grass clippings, dust, etc. are discharged along with the air around the grass collecting container, and there is a risk that the discharged air may directly hit the operator.

Therefore, in view of the above-mentioned problems, the present invention aims to provide a riding mower that can improve the efficiency of collecting grass clippings as much as possible while making the entire vehicle body equipped with a grass collecting container more compact. .

Next, the operation of the first embodiment will be explained.
When mowing a lawn or the like, the mower 9 is placed on the ground and runs while rotating the cutter blade 12 around the vertical axis 11. cutter blade 1
2 rotates, it cuts the lawn, etc., and the cut grass is collected toward the passage 16 side by the wind generated by the wind raising part 15, and the grass clippings are collected along with the airflow into each duct 17, 19. The grass is fed into the grass collection container 20 through the process. On the other hand, the grass collection container 20
After the air sent inside is dusted off by the screen 27, it is exhausted to the outside from the opening end 30 through the exhaust duct 29 through the exhaust port 28. Therefore, only the grass clippings accumulate in the grass collection container 20 and can be collected following mowing. At this time, the grass clippings that have not been sorted by the net 27 of the exhaust port 28 are discharged between the front wheels 2 from the opening end 30 through the exhaust guide duct 29, but as the vehicle body 1 moves forward, Since the grass is sucked up by the mower 9, the grass cutting efficiency can be improved. In addition, since the open end 30 is oriented between the front wheels 2, the operator is not exposed to exhaust air directly and can work comfortably.

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 removed 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 end opening of the duct 19 and the grass clippings collection port 4 of the grass collection container 20 are
It is moved relative to 3. When the grass collection container 20 is made in an inclined shape, the grass clippings slide down along the slope of the bottom plate 29 while pushing open the front cover 23, so that the grass clippings can be easily removed.

If the rear wall of the grass collecting container 20 is entirely or partially made up of a transparent plate, the amount of grass clipped in the grass collecting container 20 can be easily determined visually even when the operator on the seat 39 side is driving.

Further, the grass collecting container 20 may be lifted by hydraulic cylinders 44 provided on both left and right sides or on one side as shown by the imaginary line in FIG. may be provided.

FIG. 3 shows a second embodiment, in which the exhaust guide duct 2
9 is provided integrally with the front cover 23 of the grass collecting container 20.

(Effect of the invention) According to the invention, the grass collection container 20 is placed between the front wheels 2 on the vehicle body 1 and in front of the handle 37, so that the grass collection container 20 can be installed with the bottom part lowered as much as possible. Moreover, even when the grass collection container 20 is full, the weight balance of the vehicle as a whole is favorable, so even a relatively small vehicle body 1 can be equipped with a grass collection container 20 of as large a capacity as possible. can.

In addition, since the tip of the guide duct 29 is directed from the front of the vehicle body 1 to between the front wheels 2, the front wheels 2 can reliably return the grass clippings to the grass cutting means 9 without letting them escape to the sides of the vehicle body 1. This has the advantage that the operator can work comfortably without being directly exposed to exhaust air, and that grass collection efficiency can be improved by sucking up unsorted grass clippings again.
