The first partition plate 411 moves to drive the screen plate 5 to scrape impurities on the upper surface of the filter plate 3, and meanwhile the screen plate 5 drags out the impurities floating on the liquid surface. During the movement of the net plate 5, the mounting rod 64 gradually passes through the mounting hole 511 and pushes the transmission rod 63, and the lower end of the transmission rod 63 pushes the receiving net plate 52 to gradually rotate upwards along the transition section 32. The impurities scraped off from the filter plate 3 can be gradually moved onto the receiving screen plate 52, and then the two locking bars 72 are rotated, and the locking bars 72 push the locking blocks 71 against the rotation shaft 53, at which time the receiving screen plate 52 and the fixed screen plate 51 are relatively fixed, and the bar-shaped holes 711 are aligned with the bar-shaped holes 513.
The mounting rod 64 is rotated, so that the mounting rod 64 moves in a direction away from the fixed net plate 51 and gradually breaks away from the mounting holes 511, and the net plate 5 is pulled in a direction away from the connecting rod 4111 until the connecting rod 4111 breaks away from the net plate 5, and at this time, the net plate 5 is completely detached. And the receiving net plate 52 is kept in a bending state relative to the fixed net plate 51, so that the fishing net plate 5 is conveniently taken out of the water tank 2, and the fishing net plate 5 is cleaned.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
