AI Technical Summary

Technical Problem

Traditional fish vaccination methods suffer from problems such as low efficiency, low vaccine utilization, stress damage to fish populations, and large fluctuations in soaking solution parameters. Existing equipment is not suitable for small-sized fry and has a low degree of automation.

Method used

A continuous immersion inoculation device for fish vaccines based on an Archimedes screw is used. The rotating screw pushes the fish to be evenly immersed in the vaccine soaking solution. Combined with a vaccine soaking solution circulation and recovery system and a fully automatic oxygen supply, the device monitors the damage to the fish and ensures stable inoculation parameters.

Benefits of technology

It improves vaccination efficiency, reduces human error, lowers fish stress response, maintains stable soaking solution parameters, and achieves efficient and accurate fish vaccination.

Abstract

The utility model relates to the field of veterinary instruments, and particularly discloses a fishing vaccine continuous soaking and inoculating device based on an Archimedes screw. The device comprises a fish feeding system, a vaccine soak solution conveying system, an Archimedes screw continuous soaking inoculation system, a vaccine soak solution recycling system, a movable screw rack and a driving motor box. Fish schools in the compartments are pushed to be evenly soaked in vaccine soaking liquid through rotation of the screw rods, the inoculation efficiency is improved while the space utilization rate of the screw rods is improved through the design of the horizontal screw rods, and errors caused by human factors and inoculation batches are reduced; and the vaccine soak solution in the inoculation process is recycled through the design of the vaccine soak solution recycling system, so that the operation cost of the whole system is reduced.
