Problems solved by technology

The second type is in the form of a centrifugal water pump. The impeller in the pump rotates at a high speed to generate centrifugal force, which generates negative pressure at the inlet and high pressure at the outlet. The fish water is sucked in at the negative pressure and discharged at the high pressure. bodily injury
However, the pump is intermittent. During the intermittent period of the working process, the empty c

Abstract

A vacuum fishing machine for continuously catching and classifying living fish without damage to fish is composed of water circulating suction pump, two negative-pressure fish-collecting tanks with sucking port, electric ball valve, electromagnetic valve for sucking, water level controlling switch and automatic fish discharging port, a rubber pipe for sucking fish, and an automatic control circuit.

Description

technical field [0001] The invention belongs to the technical field of seawater net cage cultivation and fishing, in particular to a continuous vacuum live fish catching and grading machine. Background technique [0002] At present, seawater culture cages tend to be large-scale. A circular cage with a circumference of 50m can raise 10-20 tons of fish. In a large-scale cage farm, the number of cages can reach 20-30. Such a huge The amount of live fish culture, the classification and catch of fish in cage culture, the transportation between nets, nets, cages, ships and shores, long-distance transportation of fish species and live fish, etc. A matched with it is a live fish catching and grading machine that not only has a large catching capacity, is convenient for grading, but does not damage the fish body. [0003] There are three types of fish suction pumps in the world. The first is the high-pressure jet type, which uses high-pressure water to spray out through the nozzle ...
