Method for automatically opening shells and extracting pearls from river mussels

Abstract

The invention discloses an automatic freshwater mussel shell opening and pearl taking method. The method comprises the following steps: 1) feeding, namely keeping a to-be-operated freshwater mussel in a vertical state, and starting to feed; 2) clamping, namely keeping the feeding state of the freshwater mussel, and clamping the freshwater mussel; 3) processing an opening, namely adopting a grinding tool, and grinding the opening of the freshwater mussel from top to bottom, so that the opening forms a notch; 4) opening shell, namely enabling a shell opening cutter to enter the notch from top to bottom, so that shell opening is realized, and taking out freshwater mussel meat and a pearl together; and 5) separating the pearl, namely separating the freshwater mussel meat and the pearl by virtue of an automatic separation mechanism, and collecting the pearl. By adopting the automatic freshwater mussel shell opening and pearl taking method, functions of clamping the freshwater mussel (automatic loading), processing the opening, opening the shell, picking and taking the freshwater mussel meat and separating the pearl are combined into a whole, multiple steps can be completed at multiple stations, different working procedures are carried out at different stations, all the actions can be carried out under automation condition, efficiency of opening the freshwater mussel shell and taking the pearl is improved, and potential safety hazard of manual processing is eliminated.

Description

technical field [0001] The invention relates to the technical field of breeding machinery, in particular to a method for automatically opening shells and extracting pearls from mussels. Background technique [0002] my country is the world's largest pearl producer, and its freshwater pearl production ranks first in the world for many years, accounting for about 95% of the world's total. According to statistics, in 2008, my country's domestic jewelry consumption reached 190 billion yuan, and the export volume was 8.341 billion US dollars. [0003] The prior art generally adopts to manually open the shells of mussels to extract pearls. The sequence of manual operations is as follows: the first step is to split the mussels into two halves with a kitchen knife (very dangerous and has potential safety hazards); The mussel meat and pearls are taken out from the mussel shells; the third step: separating the mussel meat and pearls. After the mussels are opened, the pearls and muss...
