[0038] The reciprocating linear motion of the incubation hanging net rack 10 simulates the swinging action in the spawning process of shrimps and crabs, so that the water dissolves oxygen in the incubation water tank is increased, preventing the eggs of shrimps and crabs from dying due to lack of oxygen or sticking.
[0039] In the embodiment, in order to facilitate the management of shrimps and crabs eggs of different specifications and different incubation periods, the incubation hanging net rack 10 is divided into multiple incubation areas, each incubation area is provided with an incubation box 11, and the shrimp eggs are placed in the incubation box 11 for incubation according to different specifications. Specifically, the inside of the incubation hanging net rack 10 is provided with ten incubation grooves which are closely arranged in the transverse direction, and the incubation box 11 is fixedly connected inside the incubation grooves, and the number of the incubation boxes 11 in each incubation groove is five.

The hatching tank water inlet pipe 21 and the hatching tank water outlet pipe 19 are connected to the circulating water tank 18. The height of the bottom of the hatching tank 9 at both ends is different, so that the hatching tank 9 presents a slope, so that the water flow is formed in the hatching tank 9, and the waste produced during the hatching of shrimp and crab eggs is discharged. This phenomenon of using height difference to form water self-flow is conducive to improving the hatching rate of shrimp and crab eggs, and also conforms to the current concept of low carbon and environmental protection. The water in the hatching tank 9 is more flowing, and during the hatching of shrimp and crab eggs, clean aquaculture water is injected into the hatching tank 9, and at the same time, the aquaculture wastewater is discharged. The waste produced during the hatching of shrimp and crab eggs is discharged with the water flow from the hatching tank 9, which is conducive to improving the hatching environment of shrimp eggs.
[0042] Further, in order to comply with the concept of low carbon and environmental protection, the hatching device in the embodiment is provided with a circulating water tank 18 for purifying aquaculture water.

The water storage tank 23 is provided with water storage inlet pipe 7, which is used to add clean tap water. The bottom side of the circulating water tank 18 is provided with a sewage outlet connected with a sewage pipe 20.
[0044] As shown in Figure 7 The power of the water circulation shrimp and crab ex vivo hatching device of the utility model comes from the linear reciprocating motor 16, which drives the traction rod 13 to move back and forth. The traction rod 13 drives the hatching hanging net rack 10 to slide back and forth at the upper end of the hatching water tank 9 through the traction rod connecting piece 12, so as to improve the oxygen content in the hatching water tank 9. Due to the slope of the bottom of the hatching water tank 9, the sewage flows from the hatching water tank outlet pipe 19 to the sponge filter tank 26 from top to bottom, and is filtered layer by layer through the sponge layer. The filtered water enters the nitrifying bacteria culture water tank 25, and the nitrogen element in the water is discharged in the form of nitrogen gas through the denitrification of nitrifying bacteria. After being treated by nitrifying bacteria, the water flows into the water tank 24, and after killing the microorganisms, it is stored in the water storage tank 23. The water pump 22 delivers the water in the water storage tank 23 to the hatching water tank 9 through the hatching water tank inlet pipe 21, and finally achieves the purpose of self-circulation.
