PROBLEM TO BE SOLVED: To provide an unloading device which has superior stability when damaged, and stably unloads a powder/granular material from a hold.SOLUTION: The unloading device includes: vertical transfer means that transfers a powder/granular material carried out from a hold whose interior is watertightly partitioned by bulkheads, in a vertical direction; horizontal transfer means 120 that is disposed in the center of a bottom section of the hold so as to penetrate the hull in a longitudinal direction and that is connected to the vertical transfer means, and that horizontally transfers the powder/granular material in the hold from a discharge port having a rectangular cross section, toward a lower end side of the vertical transfer means; and an air slider 140 that is disposed at a bottom section 2a of the hold in a tilted manner toward the center of the bottom section, and that transfers the powder/granular material in the hold toward the horizontal transfer means by fluidizing the material with an airstream. The discharge port of the hold having the rectangular cross section and the horizontal transfer means are connected so as to be blockable by a watertight rectangular butterfly valve 130.SELECTED DRAWING: Figure 3

    【課題】損傷時復原性が良好で、且つ船倉から粉粒体を安定的に揚荷することができる揚荷装置を提供する。【解決手段】隔壁により内部が水密となるように区画された船倉内から搬出された粉粒体を垂直方向に移送する垂直移送手段と、船倉の底部中央に船体前後方向に貫通するように配置されると共に垂直移送手段と接続され、船倉内の粉粒体を、矩形断面を有する抜出口から垂直移送手段の下端側に向けて水平方向に移送する水平移送手段120と、船倉の底部2aに底部中央に向けて傾斜するように配置され、船倉内の粉粒体を空気流により流動化させて水平移送手段に向けて移送するエアスライダ140とを備え、船倉の矩形断面を有する抜出口及び水平移送手段は、水密角型バタフライバルブ130により閉塞可能に接続されていることを特徴とする。【選択図】図3
