Background technique

Since crayfish require different nutrients at each growth stage, during the breeding process, crayfish are generally sorted according to their weight and then cultured separately.

At present, crayfish are mostly sorted manually, but manual sorting is inefficient and easy to be pinched by crayfish. In order to save manpower, some equipment for sorting crayfish has appeared, such as the patent number CN209563345U. A simple classification screen for crayfish is disclosed, which is used to classify crayfish, and specifically includes: an upper shelf, a middle shelf, a bottom shelf, a waist hole connecting plate, a shaft, a connecting rod, a foot support, a spring, a foot plate, a nut, Round tube, support rod, cotter pin; the top part between the upper shelf, middle shelf and bottom shelf is provided with a waist hole connecting plate, and is fixed to both sides of the upper shelf, middle shelf and bottom shelf with nuts. The bottom frame is connected to the shaft with an open pin hole at the top through the shaft hole on the upper part of the connecting rod, and makes slight vibration under the action of the spring to classify the lobsters. However, because the bite force of the crayfish's claws is very strong, it can be hung on the shelf by using the bite of the claws. Moreover, the shape of the crayfish is not regular enough, so it may be difficult to distinguish them according to their shapes simply by relying on different frame sizes and mechanical vibrations. idealized effect;

For example, the patent number CN115606623A discloses a crayfish sorting device based on machine vision, and the patent number CN114863198A discloses a crayfish quality grading method based on neural networks. The specific description is: by detecting the shrimp body at the work station Calculate the projected area or compare and analyze it with collected crayfish images to judge the growth of crayfish and classify them. The detection and classification method through artificial intelligence is relatively expensive and is not suitable for practical application in crayfish farms.
