Description

Graded screening equipment suitable for multiple fish Technical Field The utility model relates to the technical field of aquaculture equipment, in particular to grading screening equipment suitable for various fishes. Background In the aquaculture and fish processing industries, the classified screening of fish is a critical process, and the subsequent processing efficiency and the product quality are directly affected. Traditional fish classification screening methods mainly rely on manual operations or simple mechanical devices such as vibrating screens, drum screens and the like. Although the method can realize the size classification of the fishes to a certain extent, when the method faces the live fishes, the weighing and scanning mechanism is easy to capture the size information of the fishes due to the jumping and tripping characteristics of the fishes, so that the classification effect is affected, and the classification and screening of the live fishes are difficult. Furthermore, existing mechanical screening devices are typically designed for a single fish or a fixed size range, lacking versatility and flexibility. For example, some equipment screens through fixed interval's screen cloth or roller, unable according to the change dynamic adjustment screening parameter of fish size, lead to the adaptability to the fish of different kinds or different growth stages relatively poor, restricted the range of application of equipment, increased the equipment input cost of breed or processing enterprise. In view of the above, there is a need in the art for improvements. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides grading screening equipment suitable for various fishes. In order to achieve the purpose, the technical scheme adopted by the utility model is that the grading screening equipment suitable for various fishes comprises a screening track, wherein an electric conveyor belt is arranged on the inner side of the screening track and is used for conveying the fishes. The device also comprises a support, wherein the support is arranged above the screening track, the inner side of the support is rotationally connected with a screening roller, and the screening roller and the electric conveyor belt are arranged at an included angle.
