Abstract

The invention relates to a graded screening machine for live fishes. The machine comprises a horizontal swing mechanism, a fish entering bucket and fish collecting buckets which are mounted on a rack as well as cam adjusting plates, wherein the horizontal swing mechanism comprises a plurality of grids, adjusting doors mounted between adjacent grids as well as a cylindrical side wall fixedly connected to the outer edges of all grids; a cam mechanism and a spring return mechanism controlled by the cam mechanism are mounted, corresponding to each adjusting door, at the outer side of the cylindrical side wall; the cam mechanisms are adjusted by the cam adjusting plates to rotate; and the rotating shafts of the adjusting doors are driven by the spring return mechanisms to rotate so as to form gaps with set sizes between the adjusting doors and the adjacent grids. According to the graded screening machine provided by the invention, in a rotating process of the horizontal swing mechanism, live fishes can be quickly and accurately distinguished according to the sizes and different specifications of fish bodies and are collected into the corresponding fish collecting buckets, so that the grading efficiency of the live fishes is improved.

Description

technical field [0001] The invention relates to a live fish grading and screening machine, which belongs to the technical field of live fish size grading and screening. Background technique [0002] According to Malcolm C M Beveridge, 1987. Cage aquaculture [M]. England: Fishing NewsBooks Ltd. records: Johnsons in 1983 designed a rigid aluminum grill installed in the pull net to separate salmon. Its working principle is: put the ground net into the cage, drag the net to make all the fish in the cage enter into the ground net, and then drive the fish with the twisted net, and the salmon with smaller body width will pass through. The aluminum metal grilles swim out of the gaps and are kept in the cages; those with larger bodies cannot pass through the gaps of the grilles and are left in the nets for fishing and sale. The main disadvantage of this natural rigid grid is: the separation system is bulky, the area of ​​the separation grid is limited, and the rigid grid often cause...
