Abstract: In order to solve the problem that the traditional transplanter of tobacco seedling can not meet the agronomic requirements of wellcellar transplanting,  a new 2QBZ-1 wellcellar transplanter for tobacco seedling pulled by tractors is designed. By establishing a threedimensional model to reasonably arrange the structure of the well cellar production device, transplanting device, and watering device, the overall structure is more compact. Through calculation and repeated experiments, the transmission ratio of the transplanting machine transmission system is matched. The experiment shows that this machine is suitable for transplanting small seedlings with a stem height of 5-8cm. The plant spacing can be adjusted within 50-60cm, and intermittent hole watering can be achieved. The watering amount per hole is steplessly adjusted within 200-1 000mL. After transplanting, the root leakage rate is less than 2.47%, the seedling burial rate is less than 2.20%, the qualification rate is more than 95.33%. This function effectively reduces the labor intensity of tobacco farmers, improves the survival rate and production efficiency of tobacco seedlings, and significantly reduces the cost of transplanting.
