Next, a seedling box arranging machine for a pot seedling box will be described. Since the pot seedling box has a gap between the pots on the bottom side of the pot, if the pots are arranged as they are on the ground, the seedling boxes and the ground do not adhere to each other, resulting in poor stability of the arranged seedling boxes. Therefore, conventionally, the ground was previously plowed and leveled to form a floor surface for arranging the seedling boxes, the seedling boxes were arranged on the floor surface, and a plate was passed over the arranged seedling boxes. By stepping on the foot from above, soil was allowed to enter the gap between the pots, improving the stability of the seedling box. However, in this conventional method, the plowing / leveling operation, the seedling box arranging operation, and the seedling box pressing operation were performed separately, so that the working efficiency was poor.

As a second embodiment, the seedling box arranging machine 1 shown in FIGS. 17 to 19 is configured to perform the plowing / leveling operation and the seedling box pressing operation simultaneously with the seedling box arranging operation. ,
It is provided with a plowing / leveling device 160 and a seedling box holding device 170. The tillage and leveling device 160 is provided on the front side of the crawlers 33 and 33 so as to be detachable from the rotary plowing blade 161 and the rotary leveling brush 162. Plowing blade 161 and leveling brush 16

When the second seedling box transport device 72 is moved up to the non-working position when the grounding operation state is established, the second seedling box transport device 72 is moved to a non-operation state away from the ground.

The seedling box holding device 170 includes the front and rear rollers 17.
1. Support arms 174, 17 which are provided at the front end of the step frame 19 so as to be rotatable up and down, and have three seedling box pressers
Each of the seedling box holders 174 is rotatably attached to the seedling box holder mounting rod 175 supported at the tip of the support arm 17.
The horizontal bar 176 provided in the middle part of the fourth and 174 and the link 9
5,95 are connected by connecting rods 177,177. The support arms 174 and 174 are configured so that the tip can be pulled out from the middle portion. When the seedling box arranging operation is not performed, the seedling box holding members 173.
5. Extraction portions 174a, 1 of support arms 174, 174
It can be removed together with 74a.

When the second seedling box conveying devices 72, 72 are lowered to the seedling box arranging operation position, the lower surfaces of the presser belts 172 are arranged on the plowed and leveled floor. Seedling box holder 17 so that it can be pressed against
3 are positioned and the seedling boxes N, N arranged on the floor are pressed from above by the seedling box retainers 173, so that the bottoms of the seedling boxes N, N are pushed into the soil, and are placed in the gaps on the back side of the pot. Soil enters. In addition, the seedling box presser 173 on the side where the seedling boxes are already arranged presses simultaneously the edges of the seedling boxes arranged this time and the edges of the previously arranged seedling boxes adjacent thereto from above. The height of the seedling box will be the same.

When the second seedling box conveying devices 72 are rotated to the non-working position, the seedling box holding members 173.
0. Therefore, when the seedling box arranging machine 1 is connected to the seeding machine 150 and used for loading the seeded seedling boxes into the seedling box storage frame H, no trouble occurs in the operation. As a third embodiment, the seedling box arranging machine 1 shown in FIGS. 20 and 21 is provided with a seedling box holding device 180 having a different configuration. The seedling box holding device 180 has a configuration in which a vibrator 182 is mounted on a holding plate 181 having a flat bottom surface, and is supported by tips of support arms 184 and 184 provided at the front end of the step frame 19 so as to be vertically rotatable. ing. The pressing effective surface (a1 × b1) of the holding plate 181 is 2
It is wider both vertically and horizontally than the individual seedling boxes N, N (a2 × 2b2) (a1> b1, a2> 2b2).

The seedling boxes N, N arranged on the ground along the seedling box guides 87 are pressed from above by the holding plate 181 while being vibrated by the vibrator 182, and are evenly pushed into the soil. Effective pressing surface of presser plate 181 is 2
Because the seedling boxes N, N are wider both vertically and horizontally than the individual seedling boxes N,
The seedling box arranged this time and the preceding seedling box, and the seedling box arranged this time and the seedling box arranged in the previous process adjacent to it are pressed simultaneously from the top, so that the heights of all seedling boxes are aligned. Become.

In each of the embodiments described above, the seedling boxes are transported and the seedling boxes are arranged side by side so that the longitudinal direction of the seedling boxes is directed left and right.
As a fourth embodiment, as in the seedling box arranging machine 1 shown in FIG. 22, the seedling box may be transported and the seedling boxes may be arranged so that the longitudinal direction of the seedling box is directed forward and backward. When the longitudinal direction of the seedling box is directed forward and backward, there is an advantage that the processing speed can be increased because the seedling box is stable.
