Tree seedling lifter

The invention discloses a tree seedling lifter. The tree seedling lifter comprises a carriage; a sliding plate is slidably mounted at the inner side of the bottom of the carriage; a fixing frame is fixedly mounted at the end, close to an auxiliary rod, of the sliding plate; the auxiliary rod is movably mounted at the outer side of the end, away from a fixing plate, of a main rod; supporting rods are fixedly mounted at the outer side of the carriage; fixing bases are fixedly installed at the bottoms of electric push rods; wheels are movably installed at the inner sides of the fixing bases; a fixing block is fixedly installed at the bottom of the end, away from the fixing frame, of the carriage; a hydraulic cylinder is fixedly installed at the side, close to the fixing frame, of the fixing block; a connecting frame is fixedly installed at the end, close to the hydraulic cylinder, of the sliding plate; the connecting frame is fixedly connected with the hydraulic cylinder; and a bent rod is fixedly mounted at the inner side of the end, away from the carriage, of the main rod, and the bent rod is bent by 90 degrees. According to the tree seedling lifter, through the extension and retraction of operation of the hydraulic cylinder, the main rod and the auxiliary rod are further driven to rotate through the sliding plate, so that a digging bucket is driven to rotate, and seedling lifting and truck loading of trees can be achieved.
