However, because of the special irregular shape of garlic, garlic planters in China are mainly planted artificially at present. The efficiency of artificial planting is low, the labor intensity is high and the labor cost is high. Therefore, garlic planters are urgently needed to replace artificially, improve the planting efficiency and reduce the labor intensity. Degree. At present, although there are some garlic planters, the vertical planting of garlic is still a key issue. Based on the analysis of the existing garlic planters, a garlic planter based on ridge cultivation was designed to meet the agronomic requirements of ridge cultivation of garlic. At the same time, garlic orientation and garlic buds vertical into the soil were realized. The planting mode was single ridge, double row and staggered planting. Air-suction seeding is adopted to ensure single seed selection and reduce the damage rate of garlic clove. The vertical planting part accomplishes garlic orientation by inoculating bucket and duckbill planter. According to the principle of parallel four bars, garlic buds are planted upward into the soil to solve the problem of garlic vertical planting. The power transm
