る。By the way, as shown in FIG. 8, the total stroke (L) of the operation of the motor (43) is set to be larger than the actual stroke (l) required for folding, and the range of the full stroke (L) of the motor (43) is set. The spring force of the spring (53) is used as a set pressure to keep the seedling mounting body (16a) in the working posture. Even if there is play in the link mechanism (35), it is always set regardless of this. Nursery stand base by pressure (16b)
The configuration is such that the posture is maintained such that the seedling mounting body (16a) is pressed against the side. As is apparent from the above, in the seedling mounting device of the rice transplanter that forms the seedling mounting table (16) by connecting the divided seedling mounting body (16a) to the seedling mounting base body (16b) so as to be freely foldable, 16b) Split seedlings (16
The first arm (37), the second arm (39), and the support arm (42), which are support members that are folded while moving the a) in parallel to the inclined upper end side, are provided.
The divided seedlings (16a) are connected to b) via the first and second arms (37) and (39) and the support arm (42).
なお、(56)は左右摺動体(47a)(47b)を摺動案内
するガイド体である。In addition, (56) is a guide body for slidingly guiding the left and right sliding bodies (47a) and (47b).
本実施例は上記の如く構成するものにして、以下左右

るものである。Now the motor (43) from the solid line working position in FIGS. 1 and 5
To move the left and right sliding bodies (47a) and (47b) inward, pull the rod (52) after the slider (48) comes into contact with the link fitting (54). When the rod (52) is moved, the first arm (37) is turned about 90 degrees outward about the first fulcrum shaft (36) as shown in FIG. Then, the seedling carrier (16a) is pulled away from the central seedling carrier main body (16b) outward and pulled up. And the first arm (37) is approximately 90
When the upper and lower second fulcrum shafts (38) overlap each other on one straight line (R) by rotating the seedling mounting body (16) around the shaft (38).
a) is bent by about 90 degrees against the spring (55) by its own weight, and pivots downwardly, against the outer sides of the left and right ends of the seedling table main body (16b) as shown in FIG. 4 and FIG. It is stored in a bent state. In this way, the two operations of raising the left and right seedling mounting bodies (16a) once on the left and right sides of the seedling mounting base body (16a) and then folding them downward can be performed by one motor (43). It is practical and economical.

などの事故が防止できる。On the other hand, the holding force when the left and right seedling mounting bodies (16a) are held in the working posture on both the left and right sides of the seedling mounting base body (16b) is given by the spring force of the spring (53).
Even if there is play in dimensions such as backlash in each link part of the link mechanism (35), the seedling carrier (16a) is always pressed against the main body (16b) with a substantially constant spring pressure, and a predetermined working posture Can be stably maintained. In this case, the motor (43) stops driving at the set position up to the stroke end on the working posture side and sets the seedling mounting body (16a) in the working posture, so that the motor (43) is set only by the stroke of the motor (43). As compared with the means for performing the above, the variation of the stroke of the motor (43) can be tolerated, and it is not necessary to set the stroke with high accuracy.
a) When the setting operation is performed, foreign matter or the like is caught between the seedling mounting body (16a) and the main body (16b) so that the seedling mounting body (16a) becomes immovable with a gap between the main body (16b) and the like. Even if there is, the subsequent stroke of the motor (43) is
Accidents such as damage to the motor (43) can be prevented by making it absorbed in 3).
