The feeding area 2 stores materials, which can be delivered to the hatching area 4 at regular time intervals; the device area 3 is used for storing devices.

[0044] Specifically, the separation area 5 and the hatching area 4 are communicated through a filter screen 41 arranged on the body wall of the hatching area 4, so that the hatched Eriocheir sinensis enters the separation area 5 through the filter screen 41, while the shrimp shells remain in the hatching area 4, thereby realizing the separation of the shrimp shells and the Eriocheir sinensis. The storage area 6 is located below the hatching area 4 and is separated by a first partition plate 42. The separation area 5 and the storage area 6 are communicated through a separation port 51. The hatched Eriocheir sinensis enters the storage area 6 from the separation area 5 through the separation port 51 for storage. In addition, the top of the hatching area 4 is provided with a hatching lamp, which can supplement the light required for the hatching of the Eriocheir sinensis, thereby promoting the hatching of the Eriocheir sinensis. A gas supply pipe can also be arranged to provide an environment for promoting the growth of the Eriocheir sinensis.

[0045] The lower end of the hatching area 4 is provided with a first sewage outlet 43, the first sewage outlet 43 is located below the filter screen 41, the first sewage outlet 43 extends from the body wall of the hatcher 1 and is communicated with a sewage pipe 44. After the separation of the Eriocheir sinensis, the shrimp shells remaining in the hatching area 4 can be discharged from the hatcher 1 through the first sewage outlet 43. In order to avoid the hatched Eriocheir sinensis from being discharged from the first sewage outlet 43, the first partition plate 42 of the present embodiment is movable up and down, the first partition plate 42 can move up and down in the hatching area 4 and the storage area 6, and by adjusting the position of the first partition plate 42 at different time periods, the corresponding functions can be realized. In the present embodiment, the first partition plate 42 is a piston made of silica gel, which plays a sealing role. During the hatching stage, the first partition plate 42 is located at the upper end position of the filter screen 41; after hatching, the first partition plate 42 moves downward to below the filter screen 41, thereby realizing the separation of the Eriocheir sinensis; after the separation is completed, the first partition plate 42 moves downward to below the first sewage outlet 43, so that the shrimp shells and waste water can be discharged from the hatcher 1 through the sewage pipe 44, and then the hatching area 4 is washed through the top spray port 45.

[0046] The lower end of the storage area 6 is provided with a drainage filter screen 63, and the lower end of the separation area 5 is provided with a second sewage outlet 52, which is located at the lower end of the separation outlet 51 and is in communication with the sewage pipe 44. The water after hatching is discharged through the second sewage outlet 52, and then is discharged through the drainage filter screen 63-second sewage outlet 52-sewage pipe 44. The separation area 5 is provided with a baffle 53 located below the separation outlet 51, which guides the hatched Diania eximia to the storage area 6.

[0047] In this embodiment, in order to clean the hatching area 4 and the separation area 5, the upper part of the hatching area 4 and the separation area 5 is provided with a spraying port 45, and the water pump 31 in the equipment area 3 can inject water into the spraying port 45, so as to realize the flushing of the hatching area 4 and the separation area 5 under the action of water flow.

[0048] The first partition plate 42 is driven to move up and down by the lead screw lifting mechanism 34, and the lead screw lifting mechanism 34 is driven by the stepping motor 33. The stepping motor 33 is located in the equipment area 3.

[0049] The feeding area 7 and the storage area 6 are separated by a second partition plate 61, and the second partition plate 61 is provided with a feeding port 62, and the feeding port 62 is provided with a silicon rubber pad which can be opened. The silicon rubber pad blocks the feeding port 62 when it is not feeding, preventing the Diania eximia from flowing out. Under the extrusion of the first partition plate 42, a certain pressure is applied to the Diania eximia, and the Diania eximia can flow out. After the Diania eximia enters the storage area 6, the first partition plate 42 moves downward to extrude the Diania eximia, and the Diania eximia flows into the feeding area 7 from the rubber pad and flows out from the feeding pipe 71. The feeding area 7 is in communication with a feeding water inlet pipe 72, and the feeding water inlet pipe 72 can be supplied with water by the water pump 31. The feeding water inlet pipe 72 can inject water into the feeding area 7 to take out the Diania eximia to the tank where feeding is needed. The water supply and gas supply to different areas can be controlled by the multiple electromagnetic valves 32 connected to the water pump 31.

[0050] The equipment area 3 is vertically through, so that the material can be fed to the hatching area 4. The bottom surface of the feeding area 2 is provided with a feeding port, and the feeding port is provided with a rotating drum 21 which is driven to rotate by a motor. In this embodiment, the rotating drum 21 is a cylindrical structure with a notch, and the rotating drum 21 rotates to automatically feed the material taken from the feeding area 2 into the feeding port.

[0051] Working principle:

[0052] The shrimp eggs are put into the hatching area 4, and the hatching area 4 is supplied with oxygen by the water-air integrated pump, and at this time, the first partition plate 42 is located at the upper position of the filter screen 41; after the hatching is completed, the first partition plate 42 is lowered, the hatched larvae enter into the separation area 5, and then enter into the storage area 6 through the separation opening 51 for storage; the first partition plate 42 continues to be lowered, and under the action of the water pump, the water flow flushes the hatching area 4 and the separation area 5; when feeding, the first partition plate 42 continues to be lowered, and the Macrobrachium Nipponense is squeezed from the storage area 6 to the feeding area 7, and the water pump flushes the feeding area 7, so that the Macrobrachium Nipponense is taken out to the tank that needs to be fed.

[0053] In addition, a monitoring module, such as a temperature and humidity sensor, a salinity sensor, etc., can be arranged in the incubator 1 to monitor the hatching environment.

[0054] The Macrobrachium Nipponense hatching and feeding device of the embodiment example has a compact structure, can realize the separation of the shrimp shells and the Macrobrachium Nipponense larvae, and realizes the continuous hatching and supply of the Macrobrachium Nipponense larvae.
