At present, the domestic vertical planting device is mainly used in transplanters. Although it can meet the needs of most seedling transplanting, the overall structure is complex, it cannot achieve small row spacing planting, and the stability is not good enough, especially not suitable for crops such as garlic and high Density type transplanting with small row spacing and plant spacing.

The Chinese invention patent with the application number "201510493526.2" discloses a continuous upright planting mechanism and the eccentric adjustment assembly, fan-shaped opening disc, etc. included in the mechanism. The planting device realizes upright planting through the duckbill mechanism, but it has drawbacks First, the combination with agronomy is not in place, resulting in that one side cannot be planted to the edge of the border wall during the planting process, and there is a waste of land; second, the overall mechanism stability is poor. The stability of the whole structure is poor, which not only increases the failure rate but also affects the normal budding rate of garlic; third, the tugboat structure on the eccentric adjustment assembly of its key components is unstable, resulting in chaotic motion trajectory; Deformation occurs, resulting in mechanical interference.

The Chinese invention patent with the application number "201920496752.X" discloses a stable, efficient and precise upright planting device.
