The invention relates to a design method for a large dual-chamber skipping bucket and the dual-chamber skipping bucket. The skipping bucket comprises a frame, wherein a bucket box is arranged in the frame; the lower part of the bucket box is connected with a sliding groove; a fan-shaped gate is arranged on the sliding groove; the horizontal cross surface of the bucket box is rectangular; the ratio of each long edge to each wide edge of the rectangle equals to or nearly equals to 2; partition plates are arranged at the midpoints of the two opposite long edges of the rectangle; the distance between the upper edge of each partition plate and the upper edge of the bucket box is 0.5 to 0.6 times of the height of the bucket box; and the distance between the lower edge of each partition plate and the lower edge of the bucket box is 2 to 5 times of the shape dimension of the maximum material particles. According to the large dual-chamber skipping bucket designed by the design method provided by the invention, because of using the partition plates, the strength of the bucket box wall is greatly increased, the strengthening rib of the periphery is reduced, and the weight of the overall bucket box is reduced obviously. The large dual-chamber skipping bucket has a reasonable structure; the swelling phenomenon is avoided in an operation process; and the safe and reliable operation is ensured.
