Then enter the next top seedling, picking seedlings, dropping seedlings, throwing seedlings and transplanting, alternating cycles.

The invention mainly aims at the requirements of transplanting crops in dry land, and integrates continuous variable-speed movement and high-speed seedling picking and matching high-efficiency seedling transporting and seedling planting. It is suitable for transplanting seedlings with soil pots. It is a rotating box-type transmission mechanism, and the double rows of seedling claws alternately grab and place the pot seedlings in the plug tray. The continuous movement of the seedling removal device reduces the shedding of the pot seedlings caused by the vibration when the interval is stagnant, and prolongs the service life of the machine parts. The seedling fetching claws of the seedling picking device move at a non-uniform speed, which is relatively slow when grasping the seedlings, which is reliable in grasping and less damage to the pot seedlings; the middle moving process is faster, and the transplanting efficiency is improved. The seedling picking device grabs the pot seedlings in the plug tray in rows and puts them into the corresponding seedling guide tube, and the pot seedling is fed into the planting device through the seedling guide tube and the transplanting is completed.
