The invention relates to a discharge device roller structure which comprises a discharge roller, wherein the discharge roller is composed of a plurality of single roller rows which are arranged along the axial direction of the rotating shaft; each single roller row is uniformly provided with a plurality of hoppers in the circumference direction; all the single roller rows are sequentially arranged in a staggered mode in the same direction; and thus, the hoppers on the whole discharge roller in the corresponding positions are arranged along a plurality of parallel spiral lines in the axial direction. Compared with the prior art, when being used in a continuous retort furnace, the discharge device roller structure can enhance the discharge uniformity, optimizes the discharged material surface curve into small waves from V shape, overcomes the influence of wall effect during material down-going, and enhances the end product quality of clinker.
