Description of the Related Art Conventionally, a pot for raising and transplanting seedlings for transplanting rice, vegetables, beets and the like has been used as a pot for sticking a large number of rot-resistant hexagonal or square tube pots with water-soluble glue. Is used for. Then, these ordinary collective pots are separated into individual pots at the time of transplantation, but at the time of transplantation, these individual pots are planted in the field by mechanical transplantation.

On the other hand, Japanese Examined Patent Publication No. 55-30805 discloses a pot for continuous seedling transplantation in which each adjacent pot is connected by a connecting piece to form one strip from one end to the other. At the time of transplantation later, by pulling the most advanced potted seedling, it is possible to pull out to the final potted seedling, while cutting the connecting piece from the tip potted seedling and sequentially planting. Japanese Patent Sho 55
No. -30805 is to cut a separation line of a connecting piece by sandwiching a continuous potted seedling with a pair of rotating bodies having an inverted conical shape, and Japanese Patent Publication No. 63-61866 is provided radially on a rotating disc. The transplanting rod holds the tip of the pot surface and rotates to pull out the succeeding pot seedling and stop the succeeding pot seedling with the stop plate to cut the connecting piece with the preceding pot seedling. Is. Furthermore, in the case of a continuous pot for transplanting seedlings in which adjacent pots are connected by a connecting piece, the applicant of the present application discloses in Japanese Patent Application No. 4-142080 that continuous seedlings are raised on the upper surface of the bottom plate using the sled-shaped bottom plate as a ground surface. Place the collecting pot for transplantation, slide the ground surface of the field manually, and pull out the collecting pots that are sequentially connected from the feeding port provided at the rear part of the bottom plate to continue connecting to the field while maintaining the connected state. We proposed a transplanter for planting a collective pot for raising seedlings.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, a continuous pot for transplanting and raising seedlings is connected to the adjacent pots by the connecting pieces, and the connecting pots are cut off. Although an automatic transplantation mechanism has been established for the purpose of separating and transplanting into individual pots, the transplanting machine that pulls out and implants while maintaining the connected state without cutting the connecting piece is described in There is only a transplanting method in which a collecting pot body for continuous seedling raising transplant is placed on the upper surface of the sled-shaped bottom plate shown in No. 4-142080, and the field is slid in the field manually. In this case, the planting proceeds sequentially and the collecting pot body on the bottom plate is small. Then, the rear part of the bottom plate becomes lighter and floats up. Since the planting of the pot body becomes poor when it floats up, a weight for preventing floatation is always placed at the rear part of the bottom plate, but since the total weight becomes heavy, extra work was required in the pulling work. For this reason, it has been desired to develop a method for mounting a continuous collecting pot transplanter having a ground-type sled-shaped bottom plate on an agricultural machine.
