It has been. The spare seedling 14 is placed on the scraper 18 and accommodated in the seedling box 17 with the seedling box 17 that houses the scraper 18 as a tray.

  Each of the left and right spare seedling transfer devices 13 is positioned at a fixed seedling stand 19 fixed to the traveling machine body 1 side, a first seedling stand 21 positioned in front of the fixed seedling stand 19, and behind the fixed seedling stand 19. The second seedling stand 22 is configured. Each of the seedling stands 19, 21, 22 has a structure in which left and right side plates 23 are connected by a connecting member, and rollers are rotatably attached between the left and right side plates 23.

  The first seedling table 21 and the second seedling table 22 are rotatably connected to the fixed seedling table 19. By fixing the fixed seedling stand 19 to the stay 24 erected from the traveling machine body 1 side, both the preliminary seedling transfer devices 13 are attached to and supported by the traveling machine body 1.

  As shown in FIG. 1, the preliminary seedling transfer device 13 includes a deployment posture A in which the seedling stands 19, 21, and 22 are deployed in a straight line in a side view, and a first seedling stand as shown in FIG. 2. 21 and the 2nd seedling stand 22 become a folding type which can change an attitude | position to the folding attitude | position B used as the folding state folded above the fixed seedling stand 19. FIG.

  The preliminary seedling transfer device 13 in the unfolded posture A is in an inclined posture of a front height and a low height. In the deployed posture A, the front end of the first seedbed 21 protrudes forward from the front end of the traveling machine body 1. The second seedling stand 22 is positioned in the vicinity of the upper portion of the seedling supplying step 12 so that the rear end is close to the seedling placing stand 3 of the planting work machine 2.

  When the preliminary seedling 14 is placed on the roller from the front end of the first seedling stage 21 in the preliminary seedling stage 13 in the deployed posture A, the seedling box 17 that accommodates the preliminary seedling 14 comes into contact with the roller, and the preliminary seedling stage 13 Due to the inclination, the preliminary seedling 14 sequentially moves by its own weight toward the rear end of the second seedling stand 22.

  The spare seedling transfer device 13 is in the form of a roller conveyor in the unfolded posture A, the front end of the first seedling stand 21 is positioned at the heel, and the first seedling pedestal 21 is replenished with the spare seedling 14 from the heel. A plurality of preliminary seedlings 14 can be continuously supplied to the platform 13. The preliminary seedling transfer device 13 can stock a plurality of preliminary seedlings 14 placed in advance in a full length.

  An operator on the traveling machine body 1 stands at the seedling supply step 12 and easily places the seedling on the seedling stage 3 by placing the spare seedling 14 on the rear end side of the second seedling stage 22 on the seedling stage 3. It can be carried out.

  After replenishing the seedlings from the spare seedling 14 at the end of the second seedling stand 22 to the seedling placing stand 3, the tray of the spare seedling 14 that has become empty (the seedling box 17 in which the scraper 18 is installed is placed in the second seedling stand 22). When it is lowered, the preliminary seedling 14 in front moves on the roller by its own weight, becomes the next candidate for replenishment to the seedling stage 3, and the seedling stage 3 can be successively replenished with seedlings.

  The height of the second seedling stand 22 is about the height position of the steering handle 10 in the driver's seat 8 so that an operator standing in the seedling supplying step 12 can easily take the rearmost spare seedling 14. Is set high to some extent. As a result, the operator can easily take the spare seedling 14 and be replenished to the seedling stage 3 with little bending. In addition, the replenishment of the spare seedling 14 from the heel is facilitated, the worker's working posture is improved, and fatigue is reduced.

  Since the rear end of the second seedling base 22 is relatively high as described above, the position of the front end of the first seedling base 21 is relatively high. For this reason, even when the preliminary seedling transfer device 13 is in the deployed posture A and the fertilizer tank for fertilization is arranged below the first seedling stand 21, fertilizer such as paste fertilizer is supplied to the fertilizer tank from the supply port on the upper surface side. Can be easily supplied. It is also possible to replenish the spare seedling transfer device 13 from the front end of the first seedling stand 21 directly from a truck or the like.

  The preliminary seedling transfer device 13 can also deploy only the first seedling stand 21 in a state of being folded above the fixed seedling stand 19. By setting only the first seedling table 21 in the folded state, the preliminary seedling 14 can be supplied to the preliminary seedling transfer device 13 from the front end of the fixed seedling table 19. When the distance from the heel to the traveling machine body 1 is relatively close, the spare seedling 14 can be easily replenished.

  It is also possible to place the preliminary seedling 14 on the upper portion of the first seedling stand 21 in the folded state (lower portion of the first seedling stand 21 in the unfolded state) and use the first seedling stand 21 as a normal auxiliary seedling stand. it can. When the first seedling stand 21 is in a folded state, the spare seedling transfer device 13 does not protrude in front of the bonnet 4, so that the traveling performance of the traveling machine body 1 is high.

  At the time of getting on and off the driver's seat 8, at least the second seedling base 22 is folded by setting the spare seedling transfer device 13 to the folding posture B or by folding only the second seedling base 22 above the fixed seedling base 19. It is desirable to be in a state. If the fixed seedling stand 19 is located on the side of the bonnet 4 and the second seedling stand 22 is in a folded state, the spare seedling transfer device 13 does not protrude into the space on the side of the driver's seat 8, so It becomes easy.
