Double-layer grading machine of pacific saury boat

Abstract

The invention discloses a double-layer grading machine of a pacific saury boat. The double-layer grading machine of the pacific saury boat comprises a support, a first grading unit and a second grading unit are arranged on the support in sequence from top to bottom, the support is further provided with a reducer box, the first grading unit and the second grading unit are both provided with a plurality of rollers with the center lines parallel to one another, gaps between every two adjacent rollers increase sequentially from top to bottom, and the lower portions of the rollers on the first grading unit are provided with a first grading cabin, a second grading cabin, a third grading cabin and a slide plate in sequence from top to bottom, and the first grading cabin, the second grading cabin, the third grading cabin and the slide plate are separated by baffles; the first grading unit and the second grading unit are communicated through the slide plate; the lower portions of the rollers on the second grading unit are provided with a first grading cabin, a second grading cabin, a third grading cabin, a fourth grading cabin and a fifth grading cabin in sequence from top to bottom, the first grading cabin, the second grading cabin, the third grading cabin, the fourth grading cabin and the fifth grading cabin are separated by baffles, and the upper end of the first grading unit is connected with a gear box and a fish body arrangement mechanism in sequence. The double-layer grading machine of the pacific saury boat can achieve accurate grading, and the workload of workers in workshops is reduced.

Description

technical field [0001] The invention belongs to the technical field of fishery devices, and in particular relates to a double-layer sorting machine for saury ships. Background technique [0002] When working, the speed of the fish shoal is too fast, so that the fish cannot be accurately graded, and fish of different sizes and grades are mixed together. If the downward speed of the fish school is slowed down, the fish will be continuously blocked at the mouth of the tank, which will affect the production efficiency on the one hand, and on the other hand, the fish bodies will be squeezed together, which is prone to damage to the fish bodies. When the catch is large, saury cannot flow into the processing workshop quickly, and it will be blocked at the entrance and affect production efficiency. [0003] At present, in the process of catching saury, after the fish and water are separated through the fish-water separator, the separated fish body slides to the fish body sorting ma...
