The utility model relates to a structure improvement of a rotary drum type feed bucket, wherein the dry feed feeding drum is a cylindrical body with a cross section, the outer edge of the rotary body is provided with a turning convex rod, and the top center has a circular curved surface. a circular arc guide portion, between the arc guide portion and the periphery, the undulation forms a concave arc-shaped dry material receiving trough; and the center of the island seat of the convex cone is provided with a central island bearing seat pivotally connected to the control rod In order to reduce the rotation resistance of the rotation of the control rod, thereby improving the smoothness of the rotation of the dry feed drum; thus, the pig only pushes the toggle rod to rotate the dry feed drum, and the feed of the centrifuge is not It will accumulate and snap into the island seat of the convex cone to reduce the accumulation or retention of obsolete feed, effectively avoiding the mold and mildew of the feed, and is an innovative structural design to ensure healthy feeding of pigs.一種轉盤式飼料桶轉筒結構改良,其主要改良在於,乾料餵食轉筒為一斷面呈ㄇ形的圓筒體,周邊外緣設有撥轉凸桿,及其頂部中心具有圓弧曲面狀的圓弧導料部,圓弧導料部至周邊之間,起伏形成凹弧狀的乾料盛料槽;又凸錐中島座的中心裝設有樞接控料連桿的中島軸承座,藉以降低控料連桿旋轉的旋轉阻力,進而提升乾料餵食轉筒的旋轉順暢度;如此,豬隻會撥動撥轉凸桿使乾料餵食轉筒旋轉,受離心外甩的飼料不會堆積卡入凸錐中島座上,減少過時飼料囤積或滯留情形,有效避免飼料受潮生菌發霉,為一確保豬隻健康餵食的創新結構設計。
