The invention relates to the field of konjak seed protection, in particular to a konjak seed turnover frame which comprises a frame body, the frame body is of a cuboid structure, and an opening is formed in the top of the frame body. The frame body comprises a bottom frame and an upper frame; wherein the bottom frame is composed of two first connecting rods, two second connecting rods and supporting rods. The two ends of the first connecting rods are connected with the two ends of the second connecting rods respectively, the supporting rods are arranged between the two first connecting rods and are parallel to the first connecting rods, and the two ends of the supporting rods are connected with the two second connecting rods respectively. A gap is formed between every two adjacent supporting rods. The upper frame is parallel to the bottom frame. The upper frame is composed of two fourth connecting rods and two third connecting rods, wherein the two ends of the fourth connecting rods are connected with the two ends of the third connecting rods respectively, and the bottom frame is connected with the upper frame through reinforcing columns. The konjak seed turnover frame solves the problem that when the existing konjak seeds are stacked, high damage rate of konjak seeds and influence on konjak planting are caused due to no konjac seed turnover frame is available for reasonably and effectively stacking and storing the konjak seeds is solved.
