Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seedling picking device for a transplanter. Background Technology

[0002] Currently, the seedling transplanting method involves farmers digging deep pits in the planting field after making ridges, and then manually planting the seedlings one by one. This transplanting method is not only labor-intensive and slow, but also inefficient, with unstable plant spacing, which negatively impacts later growth and development. In addition, when manually processing the soil, there are many large bumps in the soil, which can affect the seedlings during subsequent covering with soil. This requires extra care during seedling transplanting, which further increases the labor intensity and time spent, making it very inconvenient.

[0003] However, in the existing technology, manual seedling removal is used, which increases the amount of manual work and results in low seedling removal efficiency. Utility Model Content
