Technical Field

[0001] The utility model relates to the technical field of seedling-raising devices, in particular to a seedling-raising device for crayfish farming. Background Technique

[0002] The main season for adult crayfish farming is in spring. Making full use of spring can complete the annual production tasks of crayfish farming in spring. However, the most suitable growth water temperature for crayfish is between 15 and 28 °C, and the temperature in spring in many places is relatively low, often below 15 °C. Therefore, when raising crayfish seedlings, the water temperature needs to be increased. After retrieval, the patent with the publication number CN217284494U discloses a seedling-raising device for crayfish farming, which circulates the heated water between the longitudinal pipe and the transverse pipe, can slowly increase the water temperature in the box, and prevents the heating pipe from directly contacting the water in the box, causing the water temperature to rise too fast and not being able to stop heating in time, which may harm the crayfish.

[0003] Although the above technical solution can increase the water temperature in the box and protect the crayfish at the same time, when in use, the position of the bottom filter screen is fixed and cannot be adjusted, which is inconvenient for fishing the crayfish at the bottom. Moreover, it can only heat the water and cannot purify the water inside. And only heating is carried out at the bottom, and the heat is difficult to quickly transfer to the top, reducing the practicability. Content of the Utility Model
