Automatic clam shell extraction device

Abstract

The invention discloses a device for automatically opening the shell of a clam and picking out a pearl. The device comprises a charging mechanism, a clamping mechanism (12), a grinding tool (13) and a shell opening knife (1), wherein the discharge opening of the charging mechanism is close to the clamping mechanism (12); the clamping mechanism (12) comprises at least two clamping plates; a to-be-operated clam is kept in a vertical state in the charging mechanism, is fed into the clamping mechanism (12) from the discharge opening, and is clamped and positioned by the two clamping plates; the clam is ground from top to bottom by adopting the grinding tool (13), so that a notch is formed in the clam; and the shell opening knife (1) enters the notch from top to bottom to open the shell, and the meat and pearl are picked out together. By adopting the method, functions including clamping, notch forming, shell opening, meat picking, pearl separating and the like for the clam are combined into a whole, different processes are carried out in different work stations, and all actions are carried out under an automatic condition, so that the efficiency for opening shell and picking out pearl for the clam can be improved, and potential safety hazard of manual handling can be eliminated.

Description

technical field [0001] The invention relates to the technical field of breeding machinery, in particular to a device for automatically opening shells and extracting pearls from river 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 an...
