Problems solved by technology

For a long time, the traditional manual net fishing method not only cannot meet the large-scale fish collection needs, but also causes great mechanical damage to the fish body, resulting in high mortality of live fish
[0003] In view of this situation, in the prior art, there is a vacuum fish suction pump or a centrifugal fish suction pump for fish collection, but when using these two kinds of equipment for fish collection, the fish body is first sucked into a holding chamber, After the accommodating cavity is full, it needs to be stopped to discharge the fish body, and then suck the fish, so it cannot achieve continuous fish harvesting, which affects the efficiency of fish harvesting

Abstract

The invention discloses a fish collecting device. The fish collecting device comprises a piston mechanism and a fish collecting barrel; the piston mechanism comprises a cylinder barrel, a piston and a pushing assembly, the piston is movably installed in the cylinder barrel and divides the cylinder barrel into a rod cavity and a rodless cavity, and the pushing assembly is connected with the piston and pushes the piston to move in the cylinder barrel; the fish collecting barrel is provided with a collecting cavity used for collecting fish bodies, the fish collecting barrel is connected with the cylinder barrel and enables the collecting cavity to communicate with the rodless cavity, and the fish collecting barrel is provided with a fish inlet door which is opened towards the interior of the collecting cavity in a one-way mode and a fish outlet door which is opened towards the exterior of the collecting cavity in a one-way mode. The pushing assembly drives the piston to move back and forth in the cylinder barrel, the fish collecting barrel continuously collects the fish bodies from a culture area and sends out the fish bodies, and the fish collecting efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of fishing equipment, in particular to a fish harvesting device. Background technique [0002] With the continuous expansion of the scale of domestic and foreign fish farming and the continuous promotion of advanced farming technologies such as deep-sea cages, the fishing and collection of large-scale fish bodies is an urgent problem to be solved. For a long time, the traditional manual net fishing method not only cannot meet the large-scale fish collection needs, but also causes great mechanical damage to the fish body, resulting in high mortality of live fish. [0003] In view of this situation, in the prior art, there is a vacuum fish suction pump or a centrifugal fish suction pump for fish collection, but when using these two kinds of equipment for fish collection, the fish body is first sucked into a holding chamber, After the accommodating cavity is full, it needs to be stopped to discharge the fish body, and t...
