A net hauler 10 including a net tablc 13 tiltably mounted on a hull 11 of a purse seiner through a mounting unit 12； and first to third rollers 15 to 17 cantilevered and placed upright on the net table 13, and rotated by a rotary drive source 14； the net hauler 10 characterized by: the mounting unit 12 including a swivel 22 and a storage mechanism 24 tiltably mounted on the swivel 22 for storing the net table 13 under the deck 19 by operating a storage hydraulic cylinder 23； the first to third rollers 15 to 17 having parallel axes, the axes of the first and third rollers 15 and 17 having an opening angle of 70-150 degrees to the axis of the second roller 16； and a net guide 73 at the end of the net table 13 where the first roller 15 is placed and the net 18 is pulled in for changing its angle around the end of the net table 13. The net hauler 10 can prevent twist and slip of the net even when directions where the net is pulled in and out are changed during net hauling.本發明係提供一種揚網機，係具備有1)藉由設置托架以可傾動狀態安裝於圍網漁船之船身之漁網桌台、及2)以懸伸狀態立設於漁網桌台上並藉由旋轉驅動源旋轉之第1～第3輥；設置托架係具有1)迴旋台、2)呈可傾動狀態安裝於迴旋台並藉由藏納用油壓缸之驅動將漁網桌台藏納於低於甲板之位置之藏納機構；第1～第3輥之軸心係成平行，且相對於第2輥之軸心，第1、第3輥之開口角係70～150度；於漁網桌台之端部，安裝第1輥供漁網進入側，設有一漁網導向器，係以漁網桌台之端部為中心並可變更角度者。藉此，即使漁網之進入方向、排出方向改變，仍可防止漁網扭轉及滑動，繼而進行揚網。
