Description

[Detailed Description of the Invention] The present invention relates to a preliminary seedling storage device provided on the vehicle body of a riding-type rice transplanter.

In a riding type rice transplanter, in order to supply seedlings to the rice transplanting machine behind the passenger car body, a spare seedling tank is attached to the passenger car body side, and the spare seedlings are placed in the tank in advance.

By the way, when replenishing spare seedlings, it is desirable for the worker to be able to transfer the seedlings by turning around backwards while sitting on the seat.For this reason, the spare seedling tank is placed on both the left and right sides of the seat. However, as the number of reserve seedling tanks increases, the amount of protrusion of the picture frame increases, making it difficult to keep it within the width limit of small special vehicles.

The present invention was developed in view of these circumstances, and consists of multiple spare seedling tanks placed horizontally that can be folded to fit within a specified width when driving on the road, and expanded outward during rice planting. To provide a spare seedling accommodating device for a riding rice transplanter configured to be able to load a large number of spare seedlings.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a passenger vehicle body, and a rice transplanting machine 3 is connected to the rear portion of the passenger vehicle body 1 via a lift mechanism 2. As shown in FIG.

The passenger vehicle body 1 has an engine 5 mounted on the upper part of the front of a transmission case 4 which also serves as a frame, and a front wheel 6 provided at the lower part. A rear wheel 8 is attached to the tip of the extended transmission case 7.

Behind the engine 5 is the driver's seat 9, which is used for operation.
- A seat mounting frame 12 is mounted between the left and right transmission cases 7, and a stand 13 is mounted on the seat mounting frame 12.
A seat 14 is placed through the driver's seat 9, and an operator sits on the seat 14 and performs driving operations to drive the passenger vehicle body 1.

On the other hand, the seat 140 at the rear of such a passenger vehicle body 1
Spare seedling storage devices 15 according to the present invention are provided on both the left and right sides of the location.

As shown in enlarged detail in FIGS. 2 and 3, this spare seedling storage device 15 stores two spare seedlings on the left side of the stand 13 under the seat 14, for example, by partitioning the center with a partition plate 16. tank 1
A picture frame 19 forming 7 and 1B is horizontally protruded, and a picture frame 21 forming another spare seedling tank 20 is provided above the picture frame 19.

The outer ends of these picture frames 19 and 21 are rotatably connected by a link 22, and a toggle spring 23 is inserted between the lower picture frame 19 and the link 22 so as to straddle the pivot point A between them. While being biased, the link 22 projects diagonally outward and hits a stopper 24 on the seedling frame 19 side to maintain that state.

! A stopper 25 on the picture frame 21 side hits the tilting link 22 on the inner side of the pivot point B between the picture frame 21 and the link 22 above, and holds the picture frame 21 horizontally.
The right side of 4 is configured in exactly the same way.

Next, the lift mechanism 2 connects two links 27, 2 between the seat mounting frame 12 on the passenger vehicle body side and the rolling box 26.
8 are installed in parallel in two stages, upper and lower, and these links 27
, 28 are swung up and down by hydraulic cylinders or the like to raise and lower the rolling box 26 and the rice transplanting machine 3 connected thereto.

The rice-transplanting machine 3 has a seedling tank 30 installed on a body frame 29 connected to a rolling box 26 so as to move back and forth in the left-right direction with the upper part inclined toward the passenger vehicle body.

Further, a float 31 is attached under the body frame 29, and a planting mechanism 32 is installed at the bottom of the seedling tank 30 on the side of the seedling take-out port.
are arranged facing each other, and by the movement of this mechanism 32, seedlings are cut out one by one from the seedling tank 30 and planted on the rice field.

Since the present invention is constructed as described above, when the link 22 is tilted inward when traveling on the road in the preliminary seedling storage device 15 as shown by the dashed line in FIG. The link 22 is folded down substantially horizontally by the action of the spring, and the picture frame 21 is superimposed on the inside of the seedling frame 19.

In this way, nothing extends outside the picture frame 19, and the vehicle width is kept within the width limit for small special vehicles.

On the other hand, when the link 22 is raised and projects diagonally outward as shown by the solid line in FIGS. 2 and 3, the toggle spring 2
3 is located outside the pivot point A and acts as a spring, so that the link 22 comes into contact with the stopper 24 and maintains this inclined state.

On the other hand, by raising the link 22 in this way, the image frame 21
moves away from above the picture frame 19 and approaches the link 22, and when the link 22 protrudes and tilts as described above, the stopper 25 hits the link 22, and the picture frame 21 moves away from it above the seedling frame 19. It protrudes further outward and is held horizontally.

Thus, in this case, the two spare seedling tanks 1 in the picture frame 19
7, 1B and the spare seedling tanks 20 of the picture frame 21 are arranged in parallel in two stages, upper and lower, and these spare seedling tanks 17, 18, 20
Spare seedlings can be placed on the right side of the vehicle in the same way, and seedlings can be supplied to the seedling tank 28 of the rice transplanting machine 306 during rice planting work.

As described above, according to the present invention, the plurality of spare seedling tanks 17, 18, 20 of the spare seedling storage device 15 can be folded inward to fit within the limited width of a small special vehicle, and at the same time, they can be expanded outward. It becomes possible to carry a large number of spare seedlings for replenishment.

The operation is easy because it can be performed simply by raising and lowering the assembled link 22.

Note that the present invention is not limited to the above-mentioned embodiment, and the link 220 portion may be a parallel link supported at four points, and can be similarly applied to the case of planting 4 rows or 8 rows other than 6 rows. Of course you can get it.
