Problems solved by technology

[0002] At present, in aquaculture, especially in large-scale aquaculture ponds and large-scale deep-water cage base aquaculture, due to the increasing scale of aquaculture, the output of farmed fish is also increasing. Currently, a single large-scale deep-water cage can be aquaculture 10 to 50 tons of finished live fish, so when the fish is raised large, the live fish must be caught and sold in a timely manner to ensure the economic benefits of farming, but such a large number of finished live fish must be caught and maintain a high survival rate. Fishing is a big problem due to the lack of suitable fast and efficient mechanized fishing equipment
[0003] At present, only artificial fishing can be used, or crane-type equipment and hanging baskets can be used to fish, which not only has a large fishing workload, slow fishing speed and long time, but also causes great mechanical damage to the fish, resulting in the death of live fish A high fishing rate will seriously affect the economic benefits of farming, so how to mechanize fishing quickly and efficiently is an urgent problem to be solved in the current large-scale aquaculture industry

Embodiment 1

[0032] Such as Figure 1-4 Shown, a kind of fish sucking device comprises a fish sucking pipe body 2, fish storage tank 11, vacuum pump 15 and fish driving mechanism, and the side wall of the upper end of described fish storage tank 11 is provided with fish inlet valve 13, so The lower end of the fish storage tank 11 is provided with a fish outlet valve 14, the vacuum pump 15 communicates with the upper end of the inner chamber of the fish storage tank 11 through a vacuum tube 16, the fish suction pipe body 2 is spiral, and the fish suction pipe body 2 The fish outlet is communicated with the fish inlet valve 13, and the fish suction port of the fish suction pipe body 2 is located at the center of the fish suction pipe body 2 and arranged vertically downward;

[0033] The fish suction port of the fish suction pipe body 2 is provided with a fish guide cover 21, the diameter of the fish guide cover 21 gradually increases from top to bottom, and the end of the small diameter of t...

Embodiment 2

[0043] The structure of this embodiment is basically the same as that of Embodiment 1, except that the transmission mechanism includes a driving gear connected to the rotating shaft of the motor 5 and a driven gear connected to one of the guide wheels 7, the driving gear and the driven gear Mesh. The rotating shaft of motor 5 rotates and then drives the driving gear to rotate, and the driven gear meshed with it rotates accordingly, and the guide wheel 7 connected to the driven gear rotates coaxially thereupon, thereby being able to roll along the fish suction pipe body 2, and then drive Another guide wheel 7 can also roll along the fish suction pipe body 2, so that the baffle body 8 moves forward, and the fish is driven to the fish suction mouth of the fish suction pipe positioned at the center of the net cage, which improves the efficiency of fish suction.
