[0003] Low space utilization: Ordinary seedling trays are usually laid flat or simply stacked, lacking a stable stacking structure, which results in a lot of space being occupied during transportation and storage, making it difficult to adapt to the needs of large-scale production.

[0004] Poor transport stability: Seedling trays are prone to sliding, tilting or even tipping over during transport, which can damage seedlings or spill substrate, affecting seedling quality.

[0005] Inconvenient to operate: Traditional seedling trays usually lack dedicated handles or fixing structures, making manual handling inefficient and labor-intensive, especially when transporting large quantities;

[0006] Poor drainage: Although some seedling trays have drainage holes, they lack a drainage design, which can easily lead to water accumulation and affect the health of seedling roots;

[0007] Lack of modular design: Existing transfer devices mostly adopt an integral structure, making it difficult to flexibly adjust the number of layers or individually pick up and put down a certain layer of seedling trays according to different seedling needs. Utility Model Content
