It rises further. At this time, from the state of FIG. 22A, the swing cam 264 rotates 345 degrees in the g direction, and the opening / closing cam 272 and the scraper cam 283 rotate 345 degrees in the h direction, so that the cup support 164 Is returned from the state of swinging upward to the original state (the state of FIG. 22 (a) and FIG. 25 (b)), and the planting cup 155 is further returned to the front side from the state of shaking the head to the rear side, It rises further. At this time, the open / close swing lever 266 is pushed forward by the convex portion of the open / close cam 272, and the planting cup 155 remains in a largely open state. In addition, the downward pressing of the scraper swing lever 275 by the convex portion of the scraper cam 283 is released, the scraper swing lever 275 swings back upward, and the scraper member 225 is placed on the inner surface of the planting cup 155.

Therefore, the up-and-down moving body 163 moves up and down in a fixed posture protruding backward in the horizontal direction without rotating or swinging around the third rotating shaft 175 with respect to the traveling machine body 2 side of the transplanter 1. The vertical motion body 163 moves up and down at a high speed. Similarly, the planting cup 155 also moves up and down at a high speed and the two do not move relatively violently. A swing interlocking mechanism 251 for swinging the planting cup 155 back and forth in conjunction with the vertical motion of the planting cup 155 is provided between the vertical motion body 163 and the planting cup 155. It becomes easy. Therefore, it is not necessary to change the length of the second rotating case 162 in order to change the width of the front and rear bulges when the planting cup 155 moves up and down. For example, the shape of the swing cam 264 and the cup support By changing the shape of the body 164, the width of the front and back bulges when the planting cup 155 moves up and down can be easily adjusted. For this reason, unlike the conventional case, it is not necessary to prepare different lengths of the second rotating case, different sizes of gears, etc. according to the type of seedling to be planted, and the versatility of the planting cup drive mechanism 156 This is very advantageous for manufacturing and the like.

  In addition, since the vertical movement body 163 and the planting cup 155 on the planting cup drive mechanism 156 side do not move relatively vigorously, the vertical movement of the planting cup 155 is between the vertical movement body 163 and the planting cup 155. It is also easy to provide an opening / closing interlock mechanism 252 for opening and closing the planting cup 155 in conjunction with the movement, a scraper interlocking mechanism 253 for scraping off the soil adhering to the inner surface of the planting cup 155, and the like. For this reason, the open / close interlock mechanism 252 and the scraper interlock mechanism 253 have a simple configuration as much as possible, and can open and close the planting cup 155 smoothly and accurately in conjunction with the vertical movement of the planting cup 155 or scrape off soil or the like. Can be achieved smoothly and reliably.

Further, in order to change the striations, it is only necessary to swing each rocking frame 121 to the left and right, and the striations for planting seedlings can be easily and reliably adjusted.
FIGS. 31 and 32 show another configuration example of the scraper member 225.
