The invention discloses a power transmission device of a seedling planting machine. Coaxial through holes are formed in an outer side casing and an inner side casing arranged at one end of a chain box; a pin shaft is arranged in a position of the chain box near the through holes; the two ends of the pin shaft are supported on the outer side casing and the inner side casing; a power output shaft is supported on an outer side casing and an inner side casing arranged at the other end of the chain case through a bearing; a transition shaft is supported on an outer side casing and an inner side casing arranged in the middle of the chain box through a bearing; chain wheels comprise a transition large chain wheel, a transition small chain wheel and a power output chain wheel; the diameter of the transition large chain wheel and the diameter of the power output chain wheel are greater than the diameter of the transition small chain wheel; the transition large chain wheel is arranged and fixed on the end, near the outer side casing, of the transition shaft; the transition small chain wheel is arranged and fixed on the end, near the inner side casing, of the transition shaft; and the power output chain wheel is arranged and fixed on the power output shaft. The power transmission device has the advantages that the multi-stage speed change can be carried out, and the length of the power output shaft is reduced, so that the structure of the seedling planting machine is more compact.
