Efficient combination type lifting device

An efficient combination type lifting device relates to a lifting device of a rotary drum type drying machine which is used for the industrial fields of metallurgy, chemical engineering and the like. The efficient combination type lifting device comprises a drum body and multiple levels of combination lifting plates which are sequentially arranged on the inner wall of the drum body along the feeding direction of materials in the drum body, each level of the combination lifting plates comprises a plurality of arrays of lifting plates which are circularly arrayed on the peripheral inner wall of the drum body, the two adjacent arrays of lifting plates are staggered with each other along the radial direction, and the bending degree of the lifting plates in the next level of the combination lifting plates is increased compared with the previous level. Multiple levels of combination lifting plates are arranged in the drum body of the drying machine, a lifting plate mode is added, so that the materials with differen
