AI Technical Summary
The substrate material at the bottom of existing crab farming boxes is prone to clogging the holes after long-term use. Simply using water to clean it is ineffective, and increasing water pressure may harm the crabs.
A sewage discharge device including a separation component and a decontamination component was designed. The separation of crabs and dirty sewage is achieved through a rotating worm gear mechanism, and the substrate and water can be quickly replaced through a substrate drawer and an external water pipe.
This technology enables rapid separation and cleaning of substrate and water without the need to transfer crabs, avoiding clogging of the pores and damage to the crabs, thus improving cleaning efficiency and safety.
