[0002] In the field of agricultural planting, especially for the planting of the traditional Chinese medicine Salvia miltiorrhiza, transplanting operations are a key link in ensuring the quality and yield of crop growth. Traditional transplanting of Salvia miltiorrhiza mainly relies on manual operation, which is not only labor-intensive and inefficient, but also difficult to ensure the uniformity and survival rate of seedling transplanting, which seriously restricts the scale and modernization of the Salvia miltiorrhiza planting industry. At present, the planting of Salvia miltiorrhiza in Shaanxi Province mainly adopts a planting mode of staggered transplanting of three rows in one ridge. The design of the seedling throwing mechanism of the existing transplanting equipment cannot meet the requirements of the planting agronomy. At the same time, due to the continuous and uninterrupted manual seedling throwing, it is inevitable that the operator will be negligent and fatigued, resulting in problems such as missing seedlings and duplicate seedlings.
