The utility model provides a
juvenile trionyx sinensis screening device, and relates to the technical field of
juvenile trionyx sinensis screening, the
juvenile trionyx sinensis screening device comprises a middle vibration screening frame, an upper screen frame and a lower water collecting box, the upper portion of the middle vibration screening frame is fixedly connected with the upper screen frame, the lower water collecting box is arranged below the middle vibration screening frame, the two sides of the upper screen frame are fixedly provided with side connection sliding frames, and the side connection sliding frames are connected with the middle vibration screening frame. A first lifting screw is rotatably arranged on the inner side of the side connecting sliding frame and connected with the
tail end of the middle baffle in a threaded fit mode, a middle transverse
water pipe is rotatably arranged on the front side of the middle baffle in a matched mode through a rotating shaft, and water spraying nozzles are arranged on the front portion of the middle transverse
water pipe at intervals in an array mode. The
friction force between the juvenile soft-shelled turtles and the upper screen frame and the
friction force between the juvenile soft-shelled turtles and the middle vibration screening frame are reduced through the lubricating effect of
water flow, the situation that the juvenile soft-shelled turtles are abraded and damaged through screen holes of the upper screen frame is reduced, and the problem that the juvenile soft-shelled turtles are easily damaged due to abrasion with the screen holes of the screen in the screen moving process is solved.
