になっている。The compression wheels 20, 20 at the rear of the machine body are supported by a compression wheel support member 27 from the rear end of the seedling take-out drive case 24. Further, this seedling transplanting machine is provided with irrigation tanks 28, 28 symmetrically on the left and right, and the irrigation pump 2
It is a configuration in which water is irrigated to the planting position in the field through 9. The left and right irrigation tanks 28, 28 communicate with each other at the bottom by a hose 30, and the water surfaces of the left and right tanks 28, 28 are the same, and the left and right irrigation tanks 28, 28 have the same height. Therefore, the left and right tanks 28, 28 have the same amount of water, and the left and right balance of the machine body is maintained. This improves the straightness of the airframe. Further, the upper portions of the irrigation tanks 28, 28 are shaped so that a preliminary seedling for supplying the seedlings to the seedling placing table 15 can be placed together with the seedling picking plate 31, and can be used as a preliminary seedling stand. At this time,
As shown in FIG. 5, when the preliminary seedlings are mounted only on one of the left and right irrigation tanks 28, the horizontal shaft 33 and the rods 34, 34 are operated by the irrigation tank height adjusting lever 32,
By making the heights of the left and right irrigation tanks 28, 28 different and giving the left and right irrigation tanks 28, 28 a water amount difference corresponding to the weight of the seedlings, the left and right balance of the body can be corrected.

えとなる。The drive sprockets 17b, 17b of the left and right seedling conveying units of the seedling conveying device 16 rotate at the same speed. As a result, the planting intervals of the left and right seedling planting devices 18, that is, the plant intervals in the left and right planting lines are the same. Further, the timing of passing the seedling transfer positions of the seedling transfer cups 17a, ... Is shifted from the left and right seedling transfer units by ½ of the cycle of passing the seedling transfer positions of the seedling transfer cups 17a ,. Therefore, the seedling transfer cups 17a, ... Pass through the seedling receiving position at regular intervals, and the seedling take-out device 16 can be continuously operated. Further, in this embodiment, the left and right seedling planting devices 18, 18 are provided by the shutter opening / closing plates 18b, 18b.
Since the seedling planting positions of the above are symmetrical with respect to the seedling receiving position, the timing of planting of the left and right seedling planting devices 18, 18 is shifted from each other by ½ of the cycle.
That is, the planting positions of the left and right planting strips are displaced from each other by ½ of the plant spacing in the left and right planting strips, resulting in staggered planting.
