After automatic row seedling taking, single-planting can effectively improve the efficiency of vegetable transplanting. The existing automatic transplanting machine is mainly used for plug seedling, and the seedling pot is independent and spaced in the plug tray. Therefore, the seedling taking method can only be clamped or ejected, and the seedling taking method depends on the advantages of the seedling itself, which is suitable for long stem seedlings of solanaceous plants with developed root system.

[0003] The above seedling taking and separating method is not suitable for matrix seedlings. Since the matrix seedling block is regular and stable, it can effectively prevent the seedling from falling after transplanting, and there is no barrier between the seedling blocks. Therefore, matrix seedling is more suitable for whole row seedling taking, thereby improving the efficiency of seedling taking and transplanting. Based on the above reasons, the current vegetable matrix seedling mainly adopts semi-automatic transplanting, and the seedling taking and transplanting operations still need to be completed manually, which not only has high labor intensity and low efficiency, but also is prone to seedling missing and seedling damage, thereby restricting the promotion and application of vegetable matrix seedlings. How to design a whole row seedling taking device for vegetable matrix seedlings to overcome the bottleneck of high-quality and efficient operation of the existing automatic vegetable transplanting machine has become a problem to be solved.
