This work aims at solving the problems of susceptibility of chrysanthemum seedlings with multiple fibrous roots to damage, poor adaptability of traditional clamping type transplanting machines, and unstable transplanting uprightness. According to the agronomic requirements of chrysanthemum transplanting and morphological characteristics of its seedlings, a spoon shaped clamping transplanting device of chrysanthemum seedlings was designed and optimized. A kinematic model was established based on its working principle, and a human-computer interaction analysis interface of the transplanting device was developed based on MATLAB, and the influence of key structural parameters on transplanting performance was analyzed through this interface, and the optimal parameter combination of the mechanism was determined. The transplanting trajectory was verified by simulation and field experiment. The results showed that the actual trajectory and simulation trajectory of spoon shaped clamping transplanting device were in good agreement with the theoretical design trajectory. Under the operating conditions of crank speed 67 r·min-1 and forward speed 0.19 m·s-1, the qualified rate of transplanting angle was 84.20%, the qualified rate of transplanting depth was 90.0%, the coefficient of variation (CV) of planting spacing was 5.8%. The transplanting spacing is stable, the erect degree is high, and the transplanting meets the agronomic requirements. This study can provide reference for the development of mechanized transplanting equipment for multi-fibrous root seedlings.
