Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter in which a seedling planting device is rollably connected to a free end of a link mechanism that is attached to a vehicle body so as to be able to be driven up and down.

The above rice transplanter maintains the seedling planting device at an appropriate height and posture relative to the mud surface, regardless of changes in mud depth or left/right inclination of the vehicle body, thereby adjusting the planting depth and posture. Although this was done in an attempt to make it constant, the following problem occurred.

In other words, in the above-mentioned rice transplanter, when transporting it by loading it on a truck or storing it in a warehouse, it is possible to separate the vehicle body and the seedling planting device so that the machine body can be stored in a compact state. For this reason, a method has been proposed in which a support frame that supports the seedling planting device in a rollable manner is removably attached to the free end of the link mechanism using bolts or the like. In this case, the work of inserting the bolt through the support frame and the link mechanism while aligning them is cumbersome and time-consuming, making it difficult to perform the work of attaching and detaching easily and quickly.

The present invention has been developed with the above-mentioned circumstances in mind, and is designed to enable easy and quick attachment and detachment of the seedling planting device through rational modification that effectively utilizes the functions of the existing device. This is what I am trying to do.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

As shown in FIG. 1, at the rear of the vehicle body, which is equipped with left and right front wheels 1, 1, left and right rear wheels 2, 2, an engine 3, a driver's seat 4, etc., there is a slanted seedling stand 5 that is reciprocated horizontally with a constant stroke; It is equipped with a planting claw 6, a soil leveling float 7, etc., which circulates up and down along the lower end row of pine-shaped seedlings placed on the seedling platform 5, and picks out the seedlings one by one and plants them in the field. A seedling planting device 8 is provided to sequentially plant seedlings as the aircraft advances.

As shown in FIGS. 1 and 4, on the vehicle body,
An inverted U-shaped frame 9 is removably connected with bolts, and a U-shaped rod 11 that supports the seat 10 is pivotally supported at the upper end of the frame 9 so as to be swingable around the horizontal axis X. , in a state in which the arm 12 that restricts its downward swinging is pivotally supported to be movable up and down, and
It is removably provided on the locking pin 13 attached to the frame 9, and the seat 1
0 to cover the upper part of the seated worker, and the frame 9 and rod 11 removed from the vehicle body can be folded in half and stored in a compact state when the seat 10 is not needed. There is. Further, a rearview mirror 14 is attached to the U-shaped frame 9 so that a seated worker can see the state of the seedlings planted at the rear of the machine.

To attach the seedling planting device 8 to the vehicle body, a link is provided at the rear of the vehicle body with a pair of left and right lower links 15a, 15a, an upper link 15b, and a frame 15c that connects the free ends of each link 15a. Mechanism 1
A hydraulic cylinder 16 is provided to raise and lower the link mechanism 15.
A pair of left and right swing links 17a, 17a for supporting the seedling planting device 8 in a rollable manner are attached to a supporting frame 17 which is removably attached to the free end portion of the device as described later, and the lower end thereof is moved toward the inner side of the body. The seedling planting device 8 is installed in an inclined position and is configured to be able to be raised and lowered and freely rolled in order to maintain a constant planting depth and constant planting posture. be.

To removably attach the support frame 17 to the link mechanism 15, the link mechanism 15 is attached to the support frame 17.
A loop rod-shaped locked portion 19 removably engages with a hanging hook 18 provided on the link mechanism 15, and a locking pin 20 provided on the link mechanism 15 that swings back and forth with the hook 18 as a fulcrum. An engagement hole 21 is provided in the link mechanism 15 and the support frame 17 is provided with an engagement hole 21 that is removably engaged in a state where it cannot be moved vertically or laterally by movement.
Two clamp fittings 22 are arranged side by side and are operable to switch between a locking position and a locking release position using a swing lever 22a. , the seedling planting device 8 is configured to be easily and quickly attached and detached.

To explain in more detail, in order to attach the seedling planting device 8, first, the link mechanism 15 is lowered greatly,
The hook 18 is engaged with the locked part 19, and then the link mechanism 15 is slightly raised, and the locking pin 20 and the engaging hole 2 are connected with the seedling planting device 8 suspended and supported.
1, and finally, the clamp fittings 22, 22
It is sufficient to operate the seedling planting device 8 in a fixed state.
To remove it, simply follow the procedure in reverse to the above installation procedure.

Incidentally, in implementing the present invention, a plurality of the locking pins 20 may be provided, and various types of fixing devices such as bolts can be used as the fixing device 22.

Further, the present invention is also applicable to the case where the seedling planting device 8 is attached to the front part of the vehicle body.

In summary, the present invention, in the rice transplanter mentioned above,
A support frame 17 that supports the seedling planting device 15 in a rollable manner includes a locked portion 19 that removably engages with a hanging hook 18 provided on the link mechanism 15, and a locked portion 19 that removably engages with a hanging hook 18 provided on the link mechanism 15. An engagement hole 21 is provided that detachably engages with the locking pin 20 provided in the link mechanism 15 by swinging back and forth using the hook 18 as a fulcrum to prevent vertical and horizontal movement. It is characterized in that a fixture 22 that fixes the support frame 17 so that it cannot move back and forth is provided so that it can be operated to release the fixation.

That is, in order to attach the seedling planting device 8, first the link mechanism 15 is lowered greatly and the hook 1 is attached.
8 is engaged with the locked portion 19, and then the link mechanism 15 is slightly raised to engage the locking pin 20 and the engagement hole 21 while the seedling planting device 8 is suspended and supported. , Finally, the fixing tool 22 can be operated to the fixed state, and in order to detach the seedling planting device 8, it is sufficient to carry out the procedure in reverse to the installation described above. This can be done easily and quickly while making effective use of the functions of the existing link mechanism 15, without requiring the troublesome bolt insertion operations mentioned above, and thus making it even more convenient to use. We were able to obtain a suitable rice transplanter.
