Abstract
PURPOSE:To efficiently hydraulically convey fish, by operating a piston unit which has pistons on both the ends of a shaft in two pressure conveyance chambers defined by providing a partition in the center of the piston unit. CONSTITUTION:A vacuum pump 37 is driven by an electric motor 36 and solenoid valves 32, 33 are opened to heighten the degree of vacuum in suction pressure conveyance chambers 25, 26 so that fish and water in a fish tank 42 are conducted into the chambers 25, 26 through suction ports 7, 8 by the vacuum suction force. At that time, pressure conveyance ports 12, 13 remain disconnected from a pressure conveyance pipe 16 by check valves 14, 15. A water pump 20 is driven by an electric motor 46 to introduce water under pressure into a first pressurization chamber 17 through a solenoid valve 19 to move a piston unit 6 in the direction of an arrow A in the drawing by the water pressure. At that time, a first piston 4 acts so that the fish and water in the pressure conveyance chamber 25 open the check valve 14 and are moved under pressure to the pressure conveyance pipe 16 and conveyed to a chute 44. When a prescribed time has elasped, the solenoid valve 19 is shifted to introduce water under pressure into a second pressurization chamber 26. At that time, a second piston 5 acts so that the fish and water in the pressure conveyance chamber 26 open the check valve 15 and are moved under pressure to the pressure conveyance pipe 16.
