[0002] River crabs, scientifically known as Eriocheir sinensis, are a prized freshwater product. They are delicious and nutritious, and typically burrow in the muddy banks of rivers, lakes, and marshes. They are active at night and feed on fish, shrimp, animal carcasses, and grains. River crab farming has now become an important aquaculture species in my country.

[0003] In the process of raising river crabs, it is necessary to circulate and replace the water source in which they live, and to clean up the dirt mixed in the water to ensure the normal growth of the river crabs. Most existing crab farming devices have channels at the bottom of the pond to pump out water along with the dirt, filter it, and then pump the water back into the pond. However, they do not clean up the floating objects on the water surface, which requires manual retrieval and cleaning, which is very inconvenient. Utility Model Content

They are then collected in the conveying pipe 11 and sent to the lower box 10 for filtration. The filtered clean water is then pumped out by the second pump body 15 and discharged back into the breeding tank 2 through the drain pipe 5. The end of the conveying hose 3 that sucks up dirt is inserted through the bottom of the cleaning box 19. Two floats 20 are provided at the bottom of the cleaning box 19, which allows the cleaning box 19 to float on the water surface. In conjunction with the slider 21 fixed at the left end of the cleaning box 19, it slides inside the chute 18, ensuring that the cleaning box 19 always floats on the water surface to absorb the dirt when the water level inside the aquaculture pond 2 changes. The sewage sent to the lower box 10 by the conveying pipe 11 will be blocked by the filter plate 23 fixed inside the upper box 7 and deposited in the collection box 24 inside the lower box 10. The filtered water enters the upper box 7 through the filter plate 23. After a period of use, the water inside the upper box 7 can be sucked out by the pump body 2 15. Then, the bolts used to fix the fixing frame 1 8 and fixing frame 2 9 can be removed with tools to separate the upper box 7 from the lower box 10, so that the collection box 24 can be taken out from the lower box 10 for cleaning.
