Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention supports a grass collection container in a forward tilted position at the rear of the machine body, and transfers grass clippings from a mower into the grass collection container through a duct. The present invention relates to a grass collection container support structure for a riding lawn mower configured to feed grass.

[Conventional technology]

In the above-mentioned grass collection container support structure for a riding lawn mower, the grass collection container can be moved back and forth in a forward-folding position, and can be rotated around a horizontal axis in a rear position. Some have grass collection containers supported on the fuselage.

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 collection container. The reason why the grass collection container is moved rearward is to secure a space for the rotation operation so that a part of the grass collection container does not collide with the rear part of the aircraft when the attitude is changed.

[Problem that the invention seeks to solve]

In the above-mentioned structure, the operator must directly hold and operate the grass collection container in order to move the grass collection container back and forth, and rotate it upward or downward from the forward tilted position. was. 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 container back and forth, which is a hassle for the operator.

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

[Means for solving problems]

A feature of the present invention is that the above-mentioned grass collection container support structure for a riding lawn mower has the following configuration. In other words, by placing the crank member provided on the grass collection container, the grass collection container can be moved to the first position near the rear of the aircraft.
position, and a second position that is further away from the first position.
A guide rail that supports slides freely across positions.

A support rotation part provided at the rear end of the guide rail so as to support the grass collection container rotatably upward or downward at the second position.

It comes into contact with the crank member of the grass collection container to maintain the grass collection container in a forward tilted position between the first and second positions, and prevents the grass collection container from rotating downward at the position of the support rotation part. The first guide section that allows.

It comes into contact with the crank member of the grass collection container to maintain the grass collection container in a forward tilted position between the first and second positions, and prevents the grass collection container from rotating upward at the position of the support rotation part. The second guide part that allows.

By reciprocating operation of a manually operated lever provided in the control section of the aircraft so that it can be reciprocated, the grass collection container slides along the guide rail between first and second positions, and is moved downward or upward at the support rotation section. A push-pull link that interlocks and connects the manually operated lever and the crank member of the grass collection container so that it rotates.

A switching means for switching the crank member of the grass collection container between a first state in which the crank member is brought into contact with and guided by the first guide portion and a second state in which the crank member is brought into contact and guided by the second guide portion.

[Effect]

With the configuration described above, 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. Then, the grass collecting container is operated to move in the front and back direction along the guide rail, and is rotated at the second rear position. Then, the operation of moving the grass collection container to the rear second position and then rotating it, and the operation of returning to the forward tilted position at the rear second position and rotating it and then moving it forward are alternately reversible. It can be done in a specific manner.

The above-mentioned rotational operation also moves the crank member to the first position.
Alternatively, by bringing it into contact with the second guide part, it is possible to switch between downward rotation and upward rotation.

In this case, if the grass clippings in the grass collection container are to be immediately discharged onto the ground, the first state of downward rotation may be selected by the switching means. This results in
By moving the grass collection container rearward and rotating it downward using the manual operation lever, the grass clippings in the grass collection container are released onto the ground.

On the other hand, when a bag for collecting grass clippings is placed in the grass collection container and the grass clippings are collected in this bag and transported to another position, the switching means rotates upward in the second state. All you have to do is select.

In this case, when the manual operation lever is operated, the grass collecting container is moved rearward and rotated upward. If the grass collection container is turned upward in this way, the grass clippings will not spill out from the bag inside the grass collection container, so in this state, close the bag filled with grass clippings and place the bag into the grass collection container. All you have to do is pull it upwards and transport it to another location.

〔Effect of the invention〕

As mentioned above, it has become possible for the operator to move the grass collection container backwards and rotate it remotely while seated in the driver's seat, which eliminates the hassle of having to frequently leave the operator's seat. becomes less
We were able to improve the work efficiency of lawn mowing work.

This rotation operation can also be selectively switched between upward rotation and downward rotation, resulting in a flexible configuration that can accommodate various work situations.

When the grass collection container 7 is full of cut grass, the grass collection container 7
By moving only the main body 8 of the
Rotate around P ₁ to discard the grass clippings inside the main body 8. Next, its structure will be explained.

As shown in Figures 1, 2, 3, and 4, the grass collection container 7
A support shaft 12 protrudes from both sides of the main body 8, and a roller 12a is rotatably attached to the support shaft 12. Further, a pair of left and right guide rails 13 extend rearward and obliquely upward from the rear of the body, and support the main body 8 by placing rollers 12a on the guide rails 13.

A crank member 14 having two positioning holes 14a and 14b is fixed to the support shaft 12, and a crank arm 15 having a guide pin 15a at its tip is rotatably attached. on the other hand,
A manual operating lever 17 is pivotally supported around a horizontal axis _P2 near the driver's seat 16 of the control section 4 of the aircraft, and an operating arm 17a extending from the manual operating lever 17 has a , a push-pull link 18 is connected, and the other end of this 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. has been done.

1, 3, and 4 show a state in which the connecting pin 19 is inserted into the positioning hole 14b on the lower side of the crank member 14 (corresponding to the first state). In this state, if the manual operation lever 17 is operated downward,
Due to the action of the push/pull link 18 and the crank member 14, the main body 8 attempts to rotate counterclockwise at that position, but the guide pin 15a of the crank arm 15 Rotation is prevented by contacting with.

Therefore, when the manual lever 17 is operated, the main body 8 does not rotate, but moves rearward along the guide rail 13 from the first position shown by the solid line in FIG. 1 while maintaining the forward tilted posture. Then, the main body 8 moves to the second position at the rear end of the guide rail 13, and the roller 12a moves to the recess 13a at the rear end of the guide rail 13.
(corresponding to the support rotation part), the guide pin 15a of the crank arm 15 and the first guide part 20
The state of contact with the object disappears. As a result, 2 in Figure 1
As shown by the dot-dashed line, the push operation from the manual operation lever 17 via the push-pull link 18 is converted into a rotation operation by the crank member 14, and the main body 8 is moved around the horizontal axis P ₁ in the recess 13a. The main body 8 is rotated downward by the surroundings to be in the downward position.
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 is rotated in the opposite direction around the horizontal axis _P1 of the recess 13a to the original forward-tilted 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 returned, the forward tilted position returns to the first position shown by the solid line in FIG. It is operated by returning it to the front.

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 14 of the crank member 14.
a with a connecting pin 19 (corresponding to the second state).

When the manual operation lever 17 is operated in this state, 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 second guide portion 21. The main body 8 moves to the second position at the rear end of the guide rail 13 while maintaining the forward tilted posture. And roller 12
When a falls into the recess 13a, the main body 8
rotates clockwise and assumes an upward position. 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 8 can be switched.
