摘要

PURPOSE: A submarine environment enhancing device with combined use for picking fishes and shellfishes is provided to enhance the submarine environment by removing rubbish(impurities) scattering in the submarine and inputting nutrients. CONSTITUTION: A blast pipe having a plurality of fixed type nozzles and engaged type nozzles is mounted on the top of a suction port(7) formed in front of a digger body(1) to be connected to a blast hose(3). A plurality of digger blades(5) are engaged to the bottom thereof. A half-tone(6) is mounted on both sides thereof, with a skid plate(24) mounted therebelow. A discharge pipe(9) with a discharge slot for discharging a mixture of ground materials and nutrients is mounted on the rear end thereof to be connected to a discharge hose(8). A harrow plate(10) is hinged to the back thereof by a hinge portion(9b). A suction hose(2) is connected to a suction duct(2b) mounted on an upper part of the digger body(1). A distributing pipe(14) for a blast hose and a distributing pipe(13) for discharging are connected to the top end of the blast hose(3) and discharge hose(8) and are mounted by means of a compressor(11) and a control valve(16) mounted on a hull.
