The invention provides an automatic transplanter for plug seedlings, comprising a
transplanting mechanical hand mechanism, a planer-type mechanical arm mechanism, a
seedling plug, a
flowerpot conveying mechanism and a stand. The automatic transplanter for the plug seedlings is characterized in that the planer-type mechanical arm mechanism is provided with a mechanical arm horizontal movement guiderail and a synchronous belt on the upper part of the stand, the mechanical arm horizontal moving guide rail is connected with a mechanical arm connection plate in a sliding way, and the mechanical arm connection plate is connected with the synchronous belt and provided with a mechanical arm vertical movement guide rail and a transmission chain, and both ends of the mechanical arm are respectivelyarranged on the mechanical arm vertical movement guide rail and respectively connected with the transmission chain; a mechanical hand split-joint movement guide rail is assembled with a plurality ofmechanical hands in a sliding way, the end part of a cylinder
piston rod is connected with a fore-end mechanical hand, and inelastic connection belts are arranged among the mechanical hands; the
transplanting mechanical hand mechanism is fixedly connected with a mechanical finger installation positioning block at the lower end of a cylinder, the cylinder
piston rod is fixedly connected with a mechanical hand installation positioning block which is fixedly connected with a finger sleeve, and a mechanical finger penetrating through the finger sleeve and the mechanical hand installation positioning block is fixedly connected on the mechanical finger installation positioning block. The automatic transplanter is characterized by replacing the manual operation with the
machine to automatically complete
transplantation of the plug seedlings of vegetables and flowers and plants and having simple structure, convenience, practicality and reliable property.
