Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a riding type lawn mower configured to send grass clippings from a mower into a grass collection container through a duct.

[Conventional technology]

In a riding lawn mower, the structure for detecting whether the grass container is full of cut grass is to install an air volume sensor in the duct or the air outlet from the grass container, and to check whether the grass container is full of cut grass or not. There is a model that is configured to use the air volume sensor to detect a decrease in air volume due to a decrease in the degree to which the air from the mower is coming out of the grass collection container when the container is full, and to issue a warning with a buzzer, lamp, etc. be.

[Problem that the invention attempts to solve]

In the above-mentioned models, it is necessary to install a warning mechanism such as an air volume sensor, a buzzer, a lamp, etc., which inevitably tends to increase production costs.

The present invention focuses on the above-mentioned problem, and aims to create a structure that allows the operator to know whether the grass collection container is full of grass clippings, while suppressing the increase in production costs as much as possible. There is.

[Means for solving problems]

The feature of the present invention is that the riding type lawn mower as described above is configured as follows. In other words, the cylindrical ventilation channel that is closed by the grass clippings when the grass collection container is almost full with grass clippings is positioned so that the entrance of the ventilation channel protrudes into the grass collection space inside the grass collection container. , and is attached to the grass collection container so that the exit of the ventilation path is located above the outside of the grass collection container, and is set so that the exit of the ventilation path is located near the driver's seat of the aircraft. .

[Effect]

With the configuration described above, the operator can easily adjust the air volume from the air exhaust passage 10 by extending his hand to the air exhaust passage outlet 10b even from the position of the driver's seat 11, as shown in FIG. 1, for example. You can feel it.

As a result, when the grass collection container 7 is almost full with grass clippings and the exhaust duct entrance 10a is closed with the grass clippings, the wind from the ventilation duct 10 can hardly be felt by hand. It can be determined that the area is almost full with cut grass.

When removing the grass container from the machine and discarding the grass clippings, if the grass container is completely full to the point that the grass clippings overflow, when the grass container is removed from the machine, a lot of grass clippings may be left behind. It will spill.

In this case, in the present invention, for example, as shown in FIG.
Since the exhaust duct inlet 10a is closed in a state before the grass collection container 7 is completely filled with cut grass, this state can be felt with the hand.

Therefore, by removing the grass collection container from the machine body before it is completely full, the grass clippings can be thrown away without spilling too much grass.

[Effect of idea]

As mentioned above, the condition of exhaust air from the grass collection container is
By configuring the system so that the operator can feel it directly, there is no need for an airflow sensor or alarm mechanism, making it possible to reduce production costs without significantly reducing the full state detection function.

Furthermore, since the work of discarding the grass clippings can be done without spilling too much of the grass clippings, the workability of post-processing the grass clippings is also improved.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 2, an engine 3 is provided at the front of the aircraft supported by front wheels 1 and rear wheels 2, and a control section 4 is provided at the center of the aircraft. The riding type lawn mower is configured so that the cut grass is sent to a grass collecting container 7 at the rear of the machine body through a duct 6.

As shown in FIG. 1, the grass collecting container 7 is composed of a bottomed cylindrical main body 8 and a lid 9.
A duct 6 from the mower 5 is connected to the duct 6, and an opening 9 for exhaust air with a dustproof net stretched at the bottom.
A is provided and fixed to the rear of the fuselage. On the other hand, the left and right portions of the main body 8 are supported by a pair of left and right guide rails (not shown) extending rearward from the rear of the fuselage, and only the main body 8 can be moved backward along the guide rails. The structure is such that the main body 8 can be rotated around the horizontal axis at the rearward movement position, and the grass clippings inside the main body 8 can be easily taken out.

As shown in FIG. 1, the grass cut by the mower 5 is deposited near the bottom of the rear end of the main body 8 by the air blown from the mower 5, and the air blown from the mower 5 is deposited through the opening of the lid 9. 9a and exits through a duct-shaped exhaust passage 10 provided on the upper surface of the main body 8. The exhaust passage 10
As shown in the figure, the air outlet 10a is arranged so that the inlet 10a of the air outlet is located inside the grass collection container 7, that is, protrudes into the grass collection space, and the outlet 10a of the air outlet 10a
0b is attached to the grass collecting container 7 so that it is located at the upper part of the outside of the grass collecting container 7. The exhaust air passage 10 is extended to the vicinity of the driver's seat 11 of the control section 4, and the exhaust air passage outlet 10b is configured to face rearward near the back of the driver's seat 11. While sitting in the air exhaust passage outlet 10b.
This allows you to reach out and observe the condition of the exhaust air.

As the lawn mowing work progresses, the grass collection container 7 becomes full of grass clippings, and as shown in FIG. , the exhaust air passing through the exhaust air passage 10 is blocked by the grass clippings, and the amount of air exiting from the air exhaust passage outlet 10b decreases rapidly. The operator senses this state with his hands and determines that the grass collection container 7 is full of cut grass.
