[0020] Referring to Figure 1 , the upper end of the feed bin 1 is provided with a feeding port 11 and a through hole 12. When it is necessary to throw feed for deep-sea net cage, the feed is pumped into the inside of the feed bin 1 through the feeding port 11, and then the ship is driven to sail to the side of the net cage to prepare for feed throwing. The lower end of the feed bin 1 can adopt an inverted conical structure, so that the feed in the inside of the feed bin 1 is more convenient to be completely pumped out for throwing.

[0021] As another embodiment, as shown in Figures 1 to 3 , the conveying mechanism 2 includes a shell 21, a pneumatic grain suction pipe 22, a spiral conveying blade 23, a support frame 24 and a driving assembly 25. One end of the support frame 24 is fixedly connected with the lower end of the shell 21, and the other end of the support frame 24 is bolted with the outer wall of the feed bin 1. One end of the pneumatic grain suction pipe 22 is communicated with the shell 21, and the other end of the pneumatic grain suction pipe 22 is communicated with the inside of the feed bin 1. The driving assembly 25 is bolted with the upper end of the feed bin 1. The spiral conveying blade 23 is welded with the driving assembly 25, and is positioned in the inside of the shell 21. The spiral conveying blade 23 is in sliding contact with the inner wall of the shell 21, and the position where the spiral conveying blade 23 is in contact with the inner wall of the shell 21 adopts a material with small friction.

[0022] After the ship sails to the deep-sea net cage where feed throwing is needed, the pneumatic grain suction pipe 22 is started to pump the dry feed in the inside of the feed bin 1 into the inside of the shell 21.
