摘要： PURPOSE:To improve the operation efficiency of a pump, by providing a conveyor which is endlessly mounted to extend vertically and has claw-provided bars for clawing and lifting garbage and by circulatively rotating the conveyor in front of the suction port of a suction hose so that the cavities of a screen do not get clogged. CONSTITUTION:A ladder-like conveyor 3, which is endlessly mounted to extend vertically and has many claw-provided bars 1 for clawing and lifting garbage, is circulatively rotated in front of the suction port 4a of a suction hose 4 by an electrically-driven pulley 5 containing a motor. At that time, claws 2 dig up earth and sand and scrape and lift the garbage to facilitate the suction of the earth and sand and keep the garbage from being sucked in. As a result, the cavities of a screen for the suction port 4a do not get clogged and the operation efficiency of a pump P is improved.
