Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot raising device for transplanting seedlings from a seedling raising tray to a transplant tray in order to grow germinated seedlings to an appropriate size.

[0002]

This seed pot raising work is usually performed manually, but the work efficiency is poor, and when seedlings are mechanically transplanted from a seedling raising tray to a transplant tray, pot raising is carried out. Since the seedling raising tray and the transplanting tray have different heights and pitches between the pots, the structure becomes extremely complicated.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, there are provided tray conveyors for carrying seedling raising trays and transplantation trays, a pawl moving mechanism for moving transplanted pawls between these tray conveyors, and a movement stop position above each tray conveyor. With a claw swing mechanism that swings the transplanting nail up and down to perform seedling picking and seedling planting, the seedlings in the seedling raising tray can be automatically and accurately transplanted to the transplanting tray by an extremely simple configuration means. , It is intended to improve the efficiency of this pot raising work.

Further, a seedling raising and transplanting tray conveyor is provided so that its vertical height can be freely adjusted, and even if the tray shape is different depending on the variety and the variety, it is possible to easily cope with this and perform an appropriate potting work. is there.

Further, the moving direction of the claw moving mechanism is orthogonal to the conveying direction of the tray conveyor so that seedlings can be picked up on the upper side and planted on the lower side.
This enables efficient and efficient potting work with minimal movement of the transplanted nail.
