An egg hatching device
By designing a screen and elastic support components inside the incubation box, combined with the oscillating motion of the drive device, the efficient separation of successfully hatched fish eggs from dead eggs in the fish egg incubation device was achieved, solving the problem of excessively long separation time and improving production efficiency.

AI Technical Summary
Technical Problem
In existing fish egg incubation devices, the separation time between successfully hatched fish eggs and unhatched dead eggs is relatively long, resulting in increased production time.
Method used
A fish egg incubation device was designed, comprising an incubation box, an incubation basket, and a support device. The bottom surface of the incubation basket is a screen with a mesh size between the size of the fish eggs before and after incubation. Combined with an elastic support component and a drive device, the fish eggs are separated through oscillation motion.
Benefits of technology
This shortens the separation time between successfully hatched fish eggs and dead eggs, thus improving production efficiency.

Abstract
This utility model relates to the field of aquaculture equipment technology, specifically a fish egg hatching device, including an incubation box, an incubation basket, and a support device. The support device is located inside the incubation box and supports the incubation basket. The support device includes four support components, each with an elastic part. The incubation basket rests against the elastic part. The sides of the incubation basket are made of wooden boards, the vertical height of which matches the elastic deformation range of the elastic part in the vertical direction. The bottom of the incubation basket is a screen, the mesh size of which is between the size of the fish eggs before and after hatching. In use, successfully hatched fish eggs can pass through the upper layer of the screen to the lower layer. When dead eggs remain at the corresponding mesh opening, manually pressing down on the incubation basket causes it to vibrate within a certain range under the action of the elastic part in the support device, thus causing the dead eggs to detach from the mesh opening. This increases the space for successfully hatched fish eggs to pass through the screen, thereby effectively shortening the production time.
