[0002] With the development of aquaculture technology and the promotion of refined aquaculture technology, the automatic grading equipment for fish size has been innovated. In the aquaculture stage, due to uneven feeding of bait and competition for predation among fish social classes, the size of fish varies during the breeding period, and the size of fish affects the overall economic benefits of fish catch. Therefore, the grading equipment for fish size is becoming more and more important. At present, when grading fish, the grading device can often grade and discharge fish of various sizes. A collection frame or conveyor belt is set at the discharge outlet to receive the graded fish, but due to the different heights of the receivers placed at the bottom of the discharge outlet, when the distance between the receiver and the discharge outlet is large, the fresh fish will jump in the distance, so that they cannot fall into the receiver. It is often necessary to pick up manually, which not only increases the labor complexity, but also affects the activity of the fish when the fish cannot be picked up in time.
[0003] At present, the Chinese utility model with the announcement number of CN219628628U relates to an efficient fish grading device, including a base and a rotating shaft, a cam seat is provided on one side of the base, a frame is hinged on the other side thereof, a plurality of screen rollers are provided in the frame, a journal is provided at one end of the screen roller, and the other end thereof contracts radially and forms a screen shaft, the journal and the screen shaft are respectively penetrated on the two side walls of the frame, the journal is connected with a driving component, an active bevel gear is provided on the screen shaft, a rotating shaft is provided on the frame, a passive bevel gear is provided on the rotating shaft, a cam is provided on the rotating shaft, and the cam is against the cam seat. The rotating shaft drives the cam and the screen roller to rotate, so that the frame drives the screen roller to swing up and down, so as to drive the tilapia to slide down slowly along the screen roller, and at the same time, the roller drives the spiral groove to rotate, so that the tilapia falls into the gap between the two screen rollers, and the smaller tilapia falls below the screen roller through the gap, while the larger tilapia slides out of the screen roller along the gap, so that continuous grading operation can be realized, which greatly improves the grading efficiency and is suitable for mass production.
