An outlet of a telescopic end of the longitudinally arranged underwater telescopic pipe 33 is in communication with an inlet of a middle part of the transversely arranged feeding pipe 34, and a side wall of the transversely arranged feeding pipe 34 is provided with a plurality of feeding nozzles 38. Two telescopic ends of the telescopic mechanism are hinged with a fixed end and a telescopic end of the longitudinally arranged underwater telescopic pipe 33 separately. The energy supply device includes a solar panel 50 and a storage battery 51 electrically connected to the solar panel, and the storage battery 51 is electrically connected to the conveying pump 31 and the telescopic mechanism.

[30] By means of the conveying pipe 30, the flexible connecting pipe 32, the longitudinally arranged underwater telescopic pipe 33 and the transversely arranged feeding pipe 34 which are in communication. with. one another in sequence, a complete conveying path is constructed. The two telescopic ends of the telescopic mechanism are hinged with the fixed end and the telescopic end of the longitudinally arranged underwater telescopic pipe 33, such that the transversely arranged feeding pipe 34 of a whole feeding end may swing and expand and contract flexibly under water, and then the change of a feeding position thereof under the water is adjusted. The transversely arranged feeding pipe 34 which is transversely arranged cooperates with the plurality of feeding nozzles 38 (the feeding nozzles 38 are in a vortex shape) arranged on the side wall, such that multipoint decentralized feeding of bait is realized. This largearea coverage simulates a more natural food distribution state, allowing more fish to be in contact with the bait at the same time, and accelerating feeding speed of fish, such that a feeding task is efficiently completed. The existence of the flexible connecting pipe 32 may facilitate the changes of swing positions of the longitudinally arranged underwater telescopic pipe 33 and the transversely arranged feeding pipe 34, and may reduce the risk of rigid damage of the whole conveying device caused by unexpected external forces such as water flow impact and fish collision, such that the situation that the fish is injured by situations such as pipeline break and falling off of parts, and safe and stable feeding of the fish is ensured. Solar power supply is a clean energy source, and compared with fuel and coal power generation, there are no hidden dangers of polluting water bodies by waste gas emission, fuel leakage, etc., such that a healthy and clean feeding environment for the fish is created.

A bottom of the storage bin 12 is fixed on the bracket 10 by means of a weight sensor 13, and a vibrator 14 is fixedly arranged on the storage bin 12. During the storage of bait in the storage bin 12, due to influence of environmental humidity, component characteristics of the bait and other factors, local caking is likely to occur. Once cakes block the outlet, the whole feeding process is interrupted, and then the vibrator 14 is started regularly or as needed to generate highfrequency vibration, which easily disperses the caked bait by conduction of mechanical vibration waves, such that an unobstructed feeding channel of the storage bin 12 is maintained, and stable and continuous feeding work is ensured.
