[0002] At present, a Chinese utility model with the announcement number CN217657751U discloses a river crab seedling cultivation device, which relates to the field of river crab seedling cultivation technology, including a cultivation box, a driving mechanism is fixedly installed on the top of the cultivation box, a control panel is fixedly installed on the side of the driving mechanism, a cultivation frame and a cleaning brush frame are movably connected to the output end of the driving mechanism, and a downpipe is fixedly installed at the bottom of the cultivation box. The linear motor driving source inside the driving plate is used to drive the cultivation frame and the cleaning brush frame to perform lifting movements through fixed hooks, so that the cultivation frame can be automatically lifted from the inside of the cultivation box to the top of the opening of the cultivation box, and the cleaning brush frame can also clean the inner wall of the cultivation box, and the entire river crab removal and the cleaning of the cultivation box are mechanized, which is more time-saving and labor-saving than manual processing, thereby reducing the labor intensity and labor cost.

[0003] The existing cultivation devices are not convenient for free combination. Generally, the bottom area of ​​the intermediate cultivation pond is limited, the avoidance device occupies a large area, and it is inconvenient to collect in the seedling pond, resulting in unsatisfactory seedling cultivation effect. At the same time, when the crab fry are cleared from the pond, the crab fry are mixed with dirt, and the screening process consumes more manpower and time, and is easy to cause mechanical damage and death of the crab fry, which is inconvenient to use. In order to solve the above-mentioned problems, we propose a device for intermediate cultivation of blue crab fry. Utility Model Content
