First, in FIG. 1, a multi-planted transplanter 2 is mounted on a rear portion of the traveling machine body 1 by a lifting link 1a so as to be able to move up and down freely, and is supported by a seedling box support frame 9 provided above the transplanter 2. In the seedling box 4, for example, both sides of the root portion of a plant such as rush are adhered with an adhesive tape, and furthermore, the band-shaped seedling sewn with a thread in a spiral so as to wind the tape is accommodated in a lying state in a horizontal posture. The band-shaped seedlings are pulled out of the seedling box 4 and held in a lying state, and are conveyed by the first conveyance mechanism 10 shown in FIGS. 2 and 3, and the band-shaped seedlings carried out there are transformed into a standing shape. A second transport mechanism 30 for transferring the seedlings to the seedling feeding device 11 is provided for each of the plurality of partition plates 12 between the partitions.

Next, a cutting blade 11a and a planting guide 13 are provided at the end of feeding of each seedling feeding device 11, and are separated by one stock by the cutting blade 11a and pivotally pivoted to a drive case 14. The seedlings captured by the planting claws 16 of the supported planting rods 15 are configured to be planted in a field scene while being guided by a planting guide 13. Therefore, in the first transport mechanism 10, an endless seedling transport belt 17 is provided at a lower portion between the partition plates 12 erected for each strip as shown in FIG. A seedling holding conveying belt 18 is provided on the upper side while maintaining a predetermined gap H corresponding to the thickness of the band-shaped seedling with respect to the conveying surface of the belt 17.
The belt-like seedlings in the horizontal position are transported while being pinched by 17,18.

The seedling holding conveyor belt 18 can freely move up and down as shown by an arrow X in FIG. 2 with a drive shaft 19 on the seedling supply end side as a fulcrum. The support frame 22 is provided with a fulcrum at the drive shaft 19. On the upper part of the L-shaped support frame 22, there is provided a plate 24 to which a handle 23 is fixed, as shown in FIG.

As shown in FIG. 5, a receiving member 26 is fixed to a bracket 25a provided on the upper edge of the partition plate 12, and an L-shaped support frame 22 is formed along the vicinity of the upper edge of the partition plate 12. The L-shaped support frame 22 is supported so as to lie up and down, and a hook 25 provided on the upper surface of the L-shaped support frame 22 is engaged with a receiving member 26 to fix the L-shaped support frame 22 at a predetermined position. Have been.

As a result, the L-shaped support frame 22 for supporting the seedling holding conveyor belt 18 is fixed at a predetermined position on the side surface of the partition plate 12 via a fixing device including the hook 25 and the receiving member 16. Even if the seedling presser transport belt 18 is in a tension state, the L-shaped support frame 22 is reinforced by the partition plate 12, and lateral deflection in the belt width direction as indicated by an arrow W in FIG. 4 is prevented. .

If the height of the receiving member 26 is adjusted to maintain a gap corresponding to the thickness of the band-shaped seedling, the shoot can be transported in good condition without damaging the sprout during the transportation of the band-shaped seedling. In addition,
The inventors of the present invention have conducted experiments that if the inclined gap is maintained at the seedling supply start side, that is, the entrance side is, for example, 15 mm, and the seedling supply end side, that is, the exit side is 10 mm, better conveyance of the band-shaped seedlings is performed. It has been confirmed.

If the receiving device 26 of the fixing device is a leaf spring, the hook 25 can be attached and detached with a single touch, so that the setting operation at the start of the supply of the band-shaped seedlings is easy. The upper seedling transport belt 18 is used for lowering the seedling transport belt when reworking
Since the band-shaped seedlings can be exposed at a distance from 17, the operability is excellent.
