8 rows of seedlings were planted in the field at a predetermined interval in the traces leveled by the floats 21, 22, 22, and the fertilizer fed from the fertilizer application pipe 10 of the fertilizer applicator 8 was applied between the rows of the planted seedlings. To be done.

When it is desired to narrow the width of the riding type rice transplanter 1, the auxiliary steps 27a, 27a are folded inward so that the seedling planting section 7 has a row of both left and right ends of the seedling placing table 23 and seedlings. The receiving plate 24 is rotated 180 degrees upward from the folding fence 29 position to be folded. At this time, first, the first threaded rod 39 with the grip and the second threaded rod with the grip 40 are rotated while being pulled toward the front to release the screw engagement with the first screw cylinder 41 and the second screw cylinder 42. The first grip rod 39 with grip and the second
With the screw rod 40 with the grip of the
The one row of left and right ends and the seedling receiving plate 24 are folded by rotating the folding fence 29 about the hinge portion 37 by about 180 degrees. Then, the upper ends of the columns 32 of the folding-side seedling platform and the upper ends of the columns 32 of the stationary-side seedling platform are in contact with each other, and are fixed by the fixtures 38 provided here. In addition, when the folding-side seedling placing table is expanded to the used state, the order may be reversed from that of folding.

[0030]

As described above, according to the seedling table folding structure of the rice transplanter of the present invention, the following effects can be obtained. A fence member integrated with the fence is provided at each adjacent portion of the fixed-side seedling placing base and the folding-side seedling placing base of the seedling placing base, and the upper ends of both fence members are pivotally rotatably attached to the folding side seedlings. Since the mounting table is rotated by about 180 degrees with respect to the fixed-side seedling mounting table so that it can be folded, both fence members also serve as a rotating member and a supporting member, which simplifies the configuration and the folding-side seedling mounting table. The operability when folding and unfolding the will be good. Also, when the folding-side seedling stand is folded, it is supported on the fence of the fixed-side seedling stand, so that the folding-side seedling stand is stably supported between the fence members facing the fence members and has sufficient strength. Can have and support.

When the folding-side seedling placing base is folded, at the pivot portion of the fence member, a predetermined length is moved in the axial direction of the pivot attaching portion to the side opposite to the seedling receiving plate provided on the inclined lower end portion of the seedling placing base. It was made possible or the tangent line between the pivotal part of the fence member and the apron part of the seedling receiving plate was made substantially orthogonal, so that the seedling receiving plate should be moved when the folding side seedling table is folded. It can be folded as it is, and quick folding work can be performed.

When the folding side seedling placing base is expanded from the folded state to the use state, the fixed side seedling placing base and the folding side seedling placing base are screwed with bolts, and the bolts are fixed with knock pins. Therefore, the fixed-side seedling mounting base and the folding-side seedling mounting base are reliably connected, and the entire seedling mounting base can be accurately reciprocated in the left-right direction with a predetermined stroke. As a result, accurate seedling planting work can be performed. Further, it is possible to prevent the bolts from loosening or coming off while the fixed-side seedling placing base and the folding-side seedling placing base are connected.

Since the seedling feeding belt stopper of the folding side seedling placing table is provided on the fixed side seedling placing table side, the structure of the seedling feeding belt stopper can be simplified. Further, the stopper can be operated reliably, the damage of the stopper is reduced, and the maintenance can be easily performed.

Since the upper fulcrum of the seedling pressing body for pressing the seedlings supplied on the seedling mounting base is provided by being supported by the fence members of the fixed-side seedling mounting base and the folding-side seedling mounting base, the supporting member of the seedling pressing body is provided. Need not be provided separately, the configuration is simplified and the number of parts can be reduced.

Since the seedling receiving plate of the folding side seedling placing table is detachable from the seedling receiving plate of the fixed side seedling placing table so that it can be folded together with the folding side seedling placing table, the folding work of the folding side seedling placing table is carried out. It can be easily done with the attachment and detachment of the backing plate, and the folding and unfolding work can be done in a short time.
