Device and method for removing head of freshwater fish by arc cutting

Abstract

The invention relates to a device for removing the head of a freshwater fish by arc cutting. The device comprises a conveyer belt mechanism, wherein a pressing plate for preventing the fish from jumping is arranged above the conveyer belt mechanism; a positioning frame is arranged at the tail end of the conveyer belt mechanism, and an arc baffle is arranged on the positioning frame; the radian of the arc baffle is consistent with or similar to that of a fish head; automatic expanding and contracting baffles are arranged on two sides of the conveyer belt mechanism; the automatic expanding and contracting baffles and the arc baffle are matched for positioning a fish body; a roller knife rack is mounted behind the arc baffle, and a plurality of arc blades which are arranged at equal angles are mounted on the roller knife rack; the radian of the blades simulates the radian of the operculum of the fish. After the fish head is cut, the baffles, positioned on the fish body pushing-out side, of the automatic expanding and contracting baffles completely contract downwards / upwards, and a rotating dial plate positioned above the fish body rotates so that the fish body is pushed down to a fish body collecting device; an automatic switchover baffle at the bottom of a positioning rack downwards reverses to be opened, and the fish head drops down from the opening to fall into a fish head collecting box below.

Description

technical field [0001] The invention relates to a freshwater fish arc-shaped cutting head removal device and method, and belongs to the technical field of freshwater fish head removal equipment. Background technique [0002] The production of freshwater fish in our country is huge. In the processing process, the head removal is basically manual operation, the processing efficiency is low, the processing efficiency and quality are difficult to guarantee, and the processing process is easy to cause secondary pollution, which greatly restricts the processing output and quality. The breakthrough in production efficiency has become a prominent problem restricting the development of aquatic product processing. In recent years, with the development of processing equipment technology, the application of mechanized head removal equipment has increased year by year. Processing enterprises have gradually adopted semi-mechanized or fully mechanized head removal equipment to replace labo...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: the existing freshwater fish decapitation equipment adopts linear cutting, and the cutting tool cuts vertically along the position of the operculum arc during decapitation, and a larger fish meat will remain beside the operculum, and this part of the fish flesh cannot Effective utilization can only be treated as a by-product, resulting in a serious waste of resources; at the same time, the degree of automation of cutting is insufficient, and it is difficult to realize a series of automatic processes such as continuous automatic feeding, automatic cutting, automatic unloading, and automatic collection of fish heads; The accuracy of head cutting and the reliability of equipment operation are also low
