Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a system for feeding grass clippings from a mower into the grass container through a duct while the grass container is in a reclined position at the rear of the machine body. A riding type lawn mower having a structure in which the grass collecting container is supported on the body so as to be operable to move the grass collecting container back and forth in a reclined position, and to be rotatable around a horizontal axis in the backward moving position. This invention relates to a support structure for a grass collection container.

[Conventional technology]

The reason why the grass collection container is rotatably supported around the horizontal axis as described above is that when the grass collection container is full of grass clippings, the lid part of the grass collection container is changed to face upward or downward. This structure is designed to make it easier to take out the grass clippings in the grass container, and the purpose of moving the grass container backwards is to prevent a part of the grass container from colliding with the rear of the aircraft during the attitude change. This is to secure space for dynamic operations.

[Problem that the invention seeks to solve]

In the above-mentioned structure, the grass collecting container must be directly operated to move the grass collecting container back and forth and to rotate the grass collecting container upward or downward from a fallen position. In other words, after mowing the lawn, the operator must get out of the driver's seat, go to the rear of the aircraft, and move and rotate the grass collection container back and forth.
This configuration was troublesome for the pilot.

The present invention has focused on this point and aims to improve the workability of removing grass clippings from the grass collection container when the grass collection container is full of clipped grass.

[Means for solving problems]

A feature of the present invention is that, in the above-mentioned grass collection container support structure for a riding lawn mower, a manual operation lever that can be reciprocated is provided in the control section of the machine body, and the manual operation lever and the grass collection container are pushed and pulled. and are interlocked and connected via a crank member, so that the grass collection container can be moved backward by forward movement of the manual operation lever, and then rotated, and the grass collection container can be moved by backward movement of the manual operation lever. The mechanism is configured such that it can be rotated back to the rearward movement position and then moved forward, and its functions and effects are as follows.

[Effect]

With the above-mentioned configuration, when the operator operates the manually operated lever in a reciprocating manner while seated in the driver's seat, this reciprocating motion is converted into a reciprocating linear motion and a reciprocating rotational motion by the push/pull link and the crank member. , the grass collection container is moved in the front-back direction and rotated in the backward movement position. The operation of moving the grass collection container backward and then rotating it, and the operation of rotating it to return to the fallen position at the backward movement position and then moving it forward can be performed alternately and reversibly.

〔Effect of the invention〕

As described above, it has become possible for the operator to remotely control the rotation of the grass collection container while sitting in the driver's seat, reducing the inconvenience of having to leave the operator's seat frequently, and mowing the lawn. The work efficiency has improved.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 7, an engine 3 is provided at the front of the aircraft body supported by front wheels 1 and rear wheels 2, a control section 4 is provided at the center, and a mower 5 is provided between the wheels 1 and 2. The riding type lawn mower is configured such that the grass cut by the mower 5 is sent through a duct 6 to a grass collection container 7 at the rear of the machine body.

As shown in FIGS. 5 and 6, the grass collection container 7 has a cylindrical shape with a bottom and is composed of a resin-molded main body 8 and a lid 9. As shown in the figures, the lid 9 has an approximately lower half for air discharge. A turf inlet 9a is also provided in the upper half, which is opened as an opening 9b for use. A net 10 is stretched on the inner surface of the lid 9, and a rubber plate 11 with radial cuts is provided in the grass input port 9a. The lid body 9 constructed as described above is bolted to the rear part of the machine body via a cover plate 24, as shown in FIG. The duct 6 is inserted into the grass input port 9a, and the grass collection container 7 as a whole is operated in a forward-leaning position. The grass cut by the mower 5 is carried by the air blown from the mower 5 into the grass collection container 7 through the duct 6, and the air blown from the mower 5 is sent to the opening 9b provided in the lid 9 and the top surface of the main body. The air exits through the provided air exhaust ports 22 and 23.

When the grass collection container 7 is full of grass clippings, only the main body 8 of the grass collection container 7 is moved rearward and rotated around a horizontal axis _P1 , which will be described later, to remove the grass clippings inside the main body 8. To explain its structure in detail, as shown in Figures 1, 2, 3, and 4, a support shaft 12 protrudes from both sides of the main body 8 of the grass collection container 7, and a roller 12a is attached to this support shaft 12. It is rotatably mounted. Further, a pair of left and right guide rails 13 extend rearward and diagonally upward from the rear of the fuselage, and the rollers 12a are attached to the guide rails 13.
The main body 8 is supported by supporting the main body 8.

More specifically, a crank member 14 having two positioning holes 14a and 14b is fixed to the support shaft 12, and a guide pin 1 is attached to the tip.
A crank arm 15 having a diameter 5a is rotatably attached. On the other hand, near the driver's seat 16 of the control section 4 of the aircraft, a manual operating lever 17 is pivotally supported around a horizontal axis _P2 so as to be freely swingable, and an end of the operating arm 17a extending from the manual operating lever 17 A push-pull link 18 is connected to the push-pull link 18, and the other end of the push-pull link 18 is connected to both the crank member 14 and the crank arm 15 by a connecting pin 19, as shown in FIGS. 3 and 4.

1, 3, and 4 show the state in which the connecting pin 19 is inserted into the positioning hole 14b on the lower side of the crank member 14. When the manual operation lever 17 is operated downward in this state, the main body 8 attempts to rotate counterclockwise at that position due to the action of the push/pull link 18 and the crank member 14.
The guide pin 15a of the crank arm 15 comes into contact with the lower guide portion 20, and the rotation is prevented. Therefore, when the manual lever 17 is operated, the main body 8 moves rearward along the guide rail 13 while maintaining its tilted posture as shown in FIG. 1 without rotating. Then, when the main body 8 moves to the rear end of the guide rail 13 and the roller 12a falls into the recess 13a at the rear end of the guide rail 13,
Since the guide pin 15a of the crank arm 15 and the guide portion 20 are no longer in contact with each other, as shown in FIG.
4, the main body 8 is rotated downward around the horizontal axis _P1 in the recess 13a, and is brought into a downward position. Now the main body 8
The grass clippings inside are falling down.

The above series of operations are reversible, and 2 in Figure 1
When the manual operation lever 17 is returned from the state shown by the dotted chain line, the main body 8 moves to the horizontal axis P ₁ at the recess 13a.
The surroundings reversely rotate it back to its original fallen position. This continues until the guide pin 15a of the crank arm 15 comes into contact with the lower surface of the guide rail 13, and when the manually operated lever 17 is further operated to return, the position is returned to the front to the position shown by the solid line in FIG. It is manipulated.

Conversely, as shown in FIG. 2, the connecting pin 19 is removed and the position of the crank arm 15 is changed to the upper side, and the push-pull link 18 and the crank arm 15 are inserted into the upper positioning hole 14a of the crank member 14.
When connected with the connecting pin 19, the manual operation lever 1
7, the clockwise rotation of the main body 8 is prevented by the contact between the guide pin 15a of the crank arm 15 and the upper guide portion 21, and the guide rail 13 is rotated while maintaining its fallen position. Move to the rear end. Then, when the roller 12a falls into the recess 13a, the main body 8 rotates clockwise and assumes an upward position, contrary to the above. This series of operations can also be performed reversibly as described above.

As described above, by changing the connection point between the push-pull link 18 and the crank member 14 and the attitude of the crank arm 15, the upward and downward rotational movements of the main body can be switched.
