A fertilized fish egg hatching equipment

Abstract

The present invention relates to the field of fish egg hatching, in particular to a fertilized fish egg hatching equipment, comprising a rotary drive mechanism, a rotary lifting mechanism, a culture ball, a return mechanism, a reciprocating drive mechanism, an intermittent pumping mechanism and a water storage tank. The fertilized fish egg The hatching equipment can drive the reciprocating drive mechanism through the drive shaft, and can also drive the rotary lifting mechanism at the same time. Through the combination of the return mechanism, the cultivation ball, the rotary driving mechanism and the rotary lifting mechanism, the swivel can drive the ball to rotate. , to avoid the effect of the fish eggs in the sphere sticking to the inner wall of the sphere, the lifting column moves up and down along the lifting ring, and then makes the sphere move up and down, forming a water potential difference, so that the fish roe enters the sphere, no need Another water washing device washes the fish eggs into the culture tank, and prevents the fish eggs from sticking by one suction and one spray, so that the fish eggs are evenly spread in the sphere, which is less likely to form fish sticks than conventional continuous spraying.

Description

technical field [0001] The invention relates to the field of fish egg hatching, in particular to a hatching device for fertilized fish eggs. Background technique [0002] The hatching of fertilized fish eggs is to put the fertilized fish eggs into the incubator, and then hatch the fish eggs. During the hatching process, in order to prevent the fish eggs from sticking, water flow is often added to the bottom of the culture tank to disperse the equipment and then The fish eggs are washed away, and the conventional water flow washing equipment often causes the fish eggs to accumulate to the bottom before the fish eggs can be washed away, and some fish eggs will stick to the inner wall of the culture tank, which is difficult to wash away. The water flow dispersing equipment can only wash away the fish roe, but cannot absorb the fish roe, which will cause most of the fish roe to accumulate in several areas of the culture tank, and cannot evenly spread the fish roe in the culture ...

AI Technical Summary

Problems solved by technology

[0005] 1. Fish eggs will stick to the inner wall of the culture tank, which is difficult to wash off;

[0006] 2. Most of the fish eggs are accumulated in several areas of the culture tank, and cannot be evenly spread in the culture tank;

[0007] 3. A large number of fish eggs are often stuck on the filter screen of the water, and additional water washing equipment is needed to wash the fish eggs into the culture tank
