In order to improve the cleaning efficiency, the truss type reciprocating structure 5 can do reciprocating motion for a plurality of times, and the working time of the brush unit 14 is prolonged.
The fish classification and gathering operation can be performed first, and the cleaning operation can be performed later. When the fish grading gathering and catching operation is carried out, the brush rotary driving mechanism keeps a non-working state, the phenomenon that the nearby fish shoals are injured due to the force generated by rotation of the brush is avoided, the phenomenon that the fish shoals are frightened and rushed everywhere can be avoided, and the fish fries cannot be transferred normally due to the attraction of fish food can be avoided. The brush does not rotate, but generates a certain friction force with the bulkhead, a certain stripping force is generated on the attachment, and the connection force between the attachment and the bulkhead is weakened under the foaming of the water body. When the cleaning operation is carried out subsequently, after the brush rotates to generate larger friction force, the attachments can be easily separated from the bulkhead.
