<P>PROBLEM TO BE SOLVED: To provide a fishnet-hoisting machine enabling fishnet-hoisting operation to be conducted with preventing the fishnet from torsioning and slipping even in case the fishnet's going into and/or a drawing-off direction is varied. <P>SOLUTION: The fishnet-hoisting machine 10 includes: a fishnet table 13 tiltably attached via a setting platform 12 to the hull 11 of a roundhaul-net fishing boat; and first to third rollers 15-17 erected in a cantilever manner on the fishnet table 13 and rotating by a rotary-driving source 14. In this machine 10, the setting platform 12 has a turning table 22 and a housing mechanism 24 tiltably attached to the turning table 22 and intended for housing the fishnet table 13 under a deck 19 by driving a hydraulic cylinder 23 for housing use; the respective axes of the first to third rollers 15-17 are parallel to one another; the respective divergence angles of the first and the third rollers 15 and 17 are 70-150° with respect to the axis of the second roller 16; and on the end of the fishnet table 13, on the side attached with the first roller 15, via which the fishnet 18 is to go into, a variable-angle fishnet guide 73 is furnished around the center of the end of the fishnet table 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
