Abstract

PURPOSE: To prevent damage of a suction port by providing a grid fixed at the suction port with a guard in one body for preventing collisions drifting logs or the like.
CONSTITUTION: A grid 8 is constructed by arranging a plurality of grid bars 28 longitudinally with side intervals to each other and welding these grid bars 28 to an encircling bar 30 with guard parts 29 on both sides. In this construction, rough lumbers going to enter into a suction duct 6 through a suction port 7 are caught by the grid 8 and checked entering. Meanwhile, when a ship runs on shallow, drifting logs, or the like, since a projected edge 32, that is, the rear edge of the suction port 7 in a suction duct member 5 is protected by a guard part 29 arranged near the front of the front rim of the projected edge 32, it is prevented from direct collisions with shallows, drifting logs or the like.
