Technical Field

[0001] The invention relates to the technical field of Procambarus clarkii screening, and in particular to a grading and screening device for Procambarus clarkii. Background Art

[0002] Procambarus clarkii is an aquatic animal of the class Crustacea, order Decapoda, family Cheraxidae. It is a freshwater economic shrimp that is widely popular among people because of its delicious meat. It has an absolute competitive advantage in the local ecological environment due to its omnivorous nature, fast growth rate and strong adaptability. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc.

[0003] The sizes of the crayfish caught are different at present, so they need to be screened during processing. Currently, most of the screening is done manually, which has the disadvantages of high labor intensity and low efficiency.
