Underwater feed feeding device

Abstract

The invention relates to an underwater feed feeding device. The underwater feed feeding device comprises a net cage, a floating box, a feed receiving disc and a feeding mechanism. The floating box is arranged in the net cage, and the floating box floats on the water surface; the feed receiving disc is arranged below the floating box, the feed receiving disc sinks into a water body, and the feed receiving disc is connected with the floating box; and the feeding mechanism is arranged on the net cage, the feeding mechanism communicates with the floating box through a conveying pipeline, the feeding mechanism is used for conveying feed to the floating box, and the floating box is used for feeding the feed underwater. According to the underwater feed feeding device, the feed is directly fed underwater, the preference of fish bodies for moving in the middle and lower layers of a water body is met, the feeding effect of the fish bodies is better, the feed conversion rate is higher, and birds on the water surface are prevented from preying on the feed. Through the underwater feed receiving disc, the feed is prevented from rapidly sinking and penetrating through the net cage, the feeding time of the fish bodies is prolonged, the preference requirements of the fish bodies for different depths during feeding can be met, and the growth of the fish bodies is facilitated.

Description

technical field [0001] The invention relates to the technical field of fish feed feeding, in particular to an underwater feed feeding device. Background technique [0002] Chinese patent CN201711084742.7 discloses a feeding device for aquaculture, which includes a floating tank, a sun visor and a motor. There is a battery, and the left end of the battery is provided with a photovoltaic converter, the light energy output end of the solar panel is connected to the light energy input end of the photovoltaic converter, and the electric energy output end of the photovoltaic converter is connected to the electric energy input end of the battery. There are LED lights on the bottom of the sun visor. In the present invention, a protective net is provided at the bottom of the buoyancy tank, and fastening screws are provided at the left and right ends of the top of the protective net, so as to avoid the collision between the aquatic products and the pusher plate during feeding, result...

Problems solved by technology

[0005] For this reason, it is necessary to provide an underwater feed feeding device, which is used to solve the problem of feeding floating feed at present. The fish body needs to swim to the water surface to feed, and there are the following disadvantages in the water surface feeding: First, the fish body is crowded and grabs food on the water surface , which is not conducive to feeding; second, the floating feed floats on the water surface and is easily preyed by birds on the water surface; third, some fish bodies are more inclined to move in the middle and lower layers of the water body, where the feeding effect is better and the feed conversion rate is higher. high
