Abstract

PROBLEM TO BE SOLVED: To accomplish easy and time-shortened operations that the transverse intervals of the seedling-transplanters are narrowed and that the narrowed seedling intervals are widened to the original one. SOLUTION: In the seedling-transplanting machine that can narrow the transverse width of the seedling transplanter by allowing the left and right outer parts of the transplanter to move inward, the first moving means 152 that moves the left and right outer parts of the transplanter in the longitudinal direction or in the vertical direction, with no position change in the transverse direction, and the second moving means 153 that moves the left and right outer part of the transplanter mainly in the transversely inner side whereby the outside part of the transplanter are allowed to move stepwise from the working position to the transversely narrowed position.

3 (O). When reducing the lateral width of the seedling planting section
Remove the retaining bolt 151 and slightly
And slide it so that the connecting pin 150
Withdrawing from the side frame body 64I, the lead cam shaft 7
1. Planting drive shaft 75, support rail 83, seedling removal amount adjustment pad
Ip 97, and the central 6-row portion of the planting depth adjustment pipe 173
Divide into the minutes and the outer two sections. And the first moving means
The pivot arm 152 with the central axis 154 as a fulcrum.
By rotating from the side to the rear,
As indicated by the dashed line, left and right outside
The part is moved backward. In addition, the second moving means
Slider 153 inward along the slide rail 66
By sliding, it is shown by a two-dot chain line in FIG.
As shown, the left and right outer parts of the
Moved to Seedling transplant with reduced lateral width of seedling planting part
13 and 14 are general views of the machine. Thus, the seedling
First movement of the left and right outer parts of the seedling planting section excluding the platform
Right and left width reduction position by two operations by means and second moving means
Right and left width of the planting area
Reduction work can be performed easily and in a short time. The traveling vehicle body 2 is shown in FIG.
As shown in FIG. 14, the spare seedling mounting tables 48, 48 are stored in the storage positions.
And auxiliary rear wheels 8a, 8a, 8b,
8b is moved inward to reduce the horizontal width.
