The invention discloses a conveying chain plate of a vegetable drying machine. The conveying chain plate comprises two side plates, wherein one end of each side plate is in an arc shape, the side plates are provided with convex chain connecting ribs, the chain connecting ribs are closer to the arc-shaped ends of the side plates, and a conveying plate is connected between the two side plates; the conveying chain plate is characterized in that the conveying plate is a waved plate, the waved plate is fully provided with through holes, and the extension direction of waves of the waved plate is vertical to the side plates. Compared with the prior art, the conveying chain plate of the vegetable drying machine, designed by the invention, has the following advantages that firstly, since the conveying plate is the waved plate, the through holes cannot be compactly pressed after vegetables are placed on the waved plate, ventilating can be formed by most of the through holes, and the drying effect is ensured; secondly, a contact mode between the conveying plate and the vegetables is changed from surface contact to line contact, the friction force is reduced, and the blanking can be smoother during blanking.
