Description

For the figure equipment of adopting of shrimp automatic well-chosen classification
Technical field
The utility model relates to aquatic products field of engineering technology, relates in particular to a kind of figure equipment of adopting for the classification of shrimp automatic well-chosen.
Background technology
China, as one of the whole world six large shrimps producing country, all will carry to international market a large amount of raw material shrimps every year.But China's raw material shrimp outlet whole price level is low, market share is few, competitiveness is not enough is the reason that causes China's raw material shrimp export volume to reduce.Along with the industrial structure deepens constantly adjustment, how to support numerous and confused rise the in shrimp field and enclose pool cultivation, large-scale cultivation base makes workman be busy with cultivation and the breeding to antenatal shrimp species, but this link that needs most a large amount of human and material resources of input, financial resources of good harvest of raw material shrimp is but often out in the cold for postpartum, cause a lot of raw material shrimps because postpartum degree of attention cause not the mortality of raw material shrimp, caused serious economic loss to enterprise and raw material shrimp aquaculture industry.
For a long time, from the raw material shrimp of just fishing for up, the mode of selected classification raw material shrimp is all to complete by the hand picked mode of workman, not only inefficiency of this mode, and also people is tired in the situation that, easily produces erroneous judgement; Relatively deficient and expensive today labour, use the mode of a large amount of labours selected normal shrimp from raw material shrimp out-of-date already, the mode that our amount in need of immediate treatment is large, equipment that floor space is little, simple in structure, cost is low, automaticity is high replaces artificial work, so not only can improve accuracy rate and the efficiency of the selected classification of raw material shrimp, but also can reduce labour's expense, improve the efficiency of having a good harvest postpartum.
Situation below the general raw material shrimp of fishing for from pond exists conventionally: conventionally can sneak into the raw material shrimp that (1) salvages because of anoxic and downright bad raw material shrimp, if remove not in time, easily normal shrimp is polluted, cause the latter rotten, be unfavorable for post-production and storage, reduced the economic worth of raw material shrimp; (2) many salvagings disembarkations and the shrimp body that floats over splendid attire raw material shrimp bucket surface are easy to be baked by hot sunlight and dead, pollute thereby can produce other normal shrimps normally during the broiling summer the season for a bumper harvest of general raw material shrimp; (3) fish in the raw material shrimp of disembarkation and be also mixed with the small-sized weeds that some are not easy with the naked eye to be found by people, easily sneak in the finished product being processed into.
Publication number is the prawn that the utility model patent of 203018326U discloses the different quality ranks of a kind of detection of the method based on machine vision classification, and simple grain induction system is wherein made up of prawn feed hopper, two vibration feed appliances, two sensors, the single-row draw-in groove of individual layer, guide groove and attitude adjusters.In this patent, the shell of prawn is very easily pulverized, and adopts the mode of vibration feeding, easily makes raw material shrimp body itself produce microlesion; Transport tape adopts on horizontal transmission mode and its only has a row sampling channel can allow material to pass through, and treating capacity is little and speed is slow.
