Deep sea cage culture feeding device

The utility model relates to the technical field of cage culture, in particular to a feeding device for deep sea cage culture, which is characterized in that spiral blades synchronously rotate clockwise to upwards convey baits deposited at the bottom of a cavity, so that the stirring uniformity of the baits is improved, the stirring efficiency of the baits is improved, and the feeding efficiency of the deep sea cage culture is improved. After the spiral blade rotates anticlockwise, the bait is discharged outwards, so that the discharging efficiency of the bait in the chamber is improved, the blockage of the device is reduced, and the practicability of the device is improved; comprising a tank body, a discharging pipe, an electromagnetic valve, a feeding pipe, a stable support, a rotating shaft, a spiral blade, a stirring rod, a first flywheel, a first motor, a first belt, a third flywheel, a second motor, a second belt and a feeding device, the tank body is installed at the top end of a net cage, a cavity is
