[0002] Planting is an important part of crop production, which is to plant the seedlings of plants in the field. In order to ensure that the seedlings do not slow down after planting and grow rapidly, the best way is to transplant them in pots. The most important part of transplanting pot seedlings is to take out the independent pot seedlings from the pot tray without damage and at high speed, and to accurately hand over the pot seedlings to the planting organization.

[0003] The structure of the existing seedling picking mechanism is relatively complex. Usually, one seedling picking mechanism can only pick up one row of seedlings in the pot, and the seedling picking efficiency is low, which cannot meet the needs of efficient agricultural production. In addition, during the process of planting seedlings in the pot, the seedling picking clamps of the existing seedling picking mechanism are prone to causing the seedlings to fall or fail to be clamped due to inaccurate movement and clamping position, thereby affecting the planting effect of the seedlings and the net rate of the seedlings.
