Abstract

The invention relates to a fish gathering device for cage culture. The fish gathering device comprises a support frame, wherein at least four clamping devices corresponding to the position of cage floating tubes are fixedly arranged below thee support frame; a power device, a rotary drum and a guide roller are fixedly arranged above the support frame; the rotary drum is parallel to the guide roller; the powder device drives the rotary drum to rotate; one end of a lifting rope is fixed to a stranded cable rotary drum, and the other end of the lifting rope downwards winds around the guide roller, is pulled by a cage bottom, winds around an opposite cage handle tube and then is fixed to the cage main floating tube; and the lifting rope is also fixedly connected with a center axis part of thecage bottom. The fish gathering device can be directly mounted and matched with an existing culture cage and can be flexibly, reliably and symmetrically arranged on the cage through skillful assemblywith the cage, transformation of the existing cage arrangement is not needed, a net lifting rotary drum is used to wind and collect a steel rope and lift netting, so that fishes cultured in the cage are gathered, manual or mechanical catching is facilitated, and the cage catching efficiency is improved.

Description

technical field [0001] The invention relates to a fish-gathering device for cage culture, which is a mechanical device for assisting net lifting operations when fish are caught in cage culture, and belongs to the technical field of marine culture equipment. Background technique [0002] Cage adult fish lifting is an important link in the breeding and circulation process. At present, there are mainly several methods of lifting nets for cage farming, including manual lifting, crane lifting and pump suction lifting. Manpower starting to catch is to lift the bottom of the net clothes by manpower, and then carry out methods such as copying fish, transport and sell the fish after being caught, which consumes a lot of manpower. Crane fishing is mainly to bring the working boat close to the frame of the net cage, hoist the net clothes in the net cage through the installed crane to gather fish, and then use the net bag to lift and transfer the adult fish to the transport ship. For th...
