The driving force output from the feeding box 23 is input to the three planting driving boxes 24, respectively. The driving force inputted to each transplanting drive box 24 is transmitted to two seedling transplanting mechanisms 25 supported by the transplanting drive box 24. The six seedling transplanting mechanisms 25 are driven by driving force from the feeding box 23 and perform seedling transplanting movements, respectively, which take out a predetermined amount of seedlings from the mat-like seedlings placed on the seedling stage 26, lower the taken-out seedlings to the agricultural land and transplant the seedlings to the soil surface of the agricultural land. The earth surface on which the seedlings are planted by each of the seedling planting mechanisms 25 is flattened by the ground floating plate 27 gliding in front of the seedling planting site.
The seedling stage 26 includes seedling placing portions for placing mat-like seedlings supplied to the six seedling transplanting mechanisms 25 in parallel in the width direction of the traveling machine 1. The seedling table 26 is supported in a state of being capable of reciprocating in the width direction of the travel machine body 1. A seedling stage transverse feed mechanism 29 (see FIG. 2) is provided so as to straddle the seedling stage 26 and the feed box 23. The seedling stage 26 is driven by a driving force input to the feeding box 23 through the seedling stage transverse feeding mechanism 29 so as to be interlocked with the seedling transplanting movement of the seedling transplanting mechanism 25 and to be reciprocated in the transverse direction. The mat-like seedlings supplied to the six seedling transplanting mechanisms 25 are transferred reciprocally in the transverse direction with respect to the seedling transplanting mechanisms 25 by the seedling carrying table 26, and the six seedling transplanting mechanisms 25 take out a predetermined amount of seedlings in order from one transverse end side to the other transverse end side of the lower end portions of the mat-like seedlings, respectively.
As shown in fig. 2, 7, 8, and 9, the coupling shaft 30 extends forward from the front portion of the feed box 23. The support member 31 is provided at the rear end portion of the link mechanism 14. The support member 31 has a sleeve portion 32 and is supported by the coupling shaft 30 on the sleeve portion 32, so that the insertion device frame 21 is supported integrally on the support member 31 so as to be able to ascend and descend.
