Abstract

The invention relates to an automatic fish grading system, and belongs to the technical field of fish culture processing. The fish sorting device comprises a fish sorting device and a fish collecting device, the fish sorting device comprises a discharging hopper, a conveying belt located below the discharging hopper and a fish sorting groove connected with the conveying belt, and a shifting plate is arranged at an inlet of the fish sorting groove; the fish collecting device comprises an inclined fish collecting groove, a detection box is installed on the lower portion of the discharging hopper, and a camera for collecting fish images is arranged in the detection box; the fish collecting device further comprises an overturning plate and a liquid level sensor located on the fish collecting groove. A brush head is arranged at one end of the rotating shaft; the overturning plate rotates by 360 degrees along the rotating shaft and is matched with the fish collecting tank; the liquid level sensor is located at the highest water line of a water tank formed by the fish collecting tank and the overturning plate. The method can be widely applied to fish culture and processing occasions.

Description

technical field [0001] The invention relates to an automatic classification system for fish, which belongs to the technical field of fish farming and processing. Background technique [0002] Before the existing fish are sold, they are usually graded according to the size of the fish, and the strategy of grading sales is adopted to ensure the maximization of profits. At present, the grading work of fish is still mainly based on artificial naked eye grading. Even if there is a grading device, it is mainly graded by a mechanical grading device, which is easy to cause damage to the fish and cannot meet the quality requirements of some fish. Therefore, there is a need for an automatic grading system with less damage to the fish. At the same time, after the fish is graded, impurities are likely to remain on the chute, which affects the use of the equipment. Frequent manual cleaning is required, and the work efficiency is relatively low. SUMMARY OF THE INVENTION [0003] In vi...
