Referring to fig. 1 and 2, the cleaning member 4 comprises a square frame 40 fixedly mounted at the upper end of the processing operation frame 1, water spraying ports 41 are fixed at the lower end of the square frame 40 at equal intervals, after the crayfish is classified, the water spraying ports 41 spray water, and the water column washes the screening frame 20 inside the processing operation frame 1, so that the soup of the auxiliary seasonings remained inside the screening frame is washed into a collecting box 314 to be collected, and the tidiness of the whole device is guaranteed.

Referring to fig. 11, in addition, the present invention further provides a grading method for cooked crayfish processing, which specifically includes the following steps:

s1, primary screening: the boiled crayfish mixed with the auxiliary seasonings is poured into the two screening frames 20, then the screening motor 25 drives the screening cams 23 to push the two screening frames 20 to shake left and right in a reciprocating mode under the action of the shaking spring rods 21, when the two screening frames 20 shake, the rotating rods 284 and the hooks 285 also rotate synchronously, the rotating rods 284 and the hooks 285 are matched to enable the crayfish to continuously move inside the screening frames 20, the seasonings attached to the surfaces of the crayfish drop through the net structure at the bottom of the screening frames 20 in the process of overturning, and meanwhile, the limbs of the crayfish dropping on the bodies of the crayfish in the cooking process also drop into the secondary processing platform 3 through the net structure at the bottom of the screening frames 20 in the shaking process.

S2, secondary screening: when the auxiliary seasonings and the crawfish limbs pass through the screening frame 20 and then fall to the mesh-shaped screening frame 31, the auxiliary seasonings pass through the mesh-shaped screening frame 31 in the falling process, the crawfish limbs cannot pass through the mesh-shaped screening frame 31, then the driving motor 344 drives the two symmetrical winding gears 343 to rotate relatively through the winding gears 343, the two winding gears 343 pull the pulling rope 341 to shorten in the rotating process, the pulling rope 341 pulls the two screening brushes 340 to move inwards synchronously along the two mesh-shaped screening frames 31, then the screening brushes 340 push the crawfish limbs at the upper end of the mesh-shaped screening frame 31 to move towards the material leaking groove 311, then the screening brushes 340 push the crawfish limbs into the material leaking groove 311, and the crawfish enters the space specially used for collecting the crawfish limbs in the collecting box 314 through the material leaking groove 311.

S3, lobster sorting: the crayfish enters the upper end of the conical shell 300 between the two guide plates 30 along the mesh-shaped separating plate 26, then the crayfish sequentially passes through the two overlapped discharge chutes 301, falls into the crayfish capturing frame 307 right below the crayfish, then the crayfish capturing frame 307 moves forward under the rotation of the conveyor belt 306, when the crayfish capturing frame 307 rotates to the lower side of the conveyor belt 306, the crayfish capturing frame 307 is turned upside down, then the crayfish enters the known conveyor device to be conveyed in a posture that the crayfish faces upwards and the crayfish faces downwards by moving the shifting piece 322, and then the crayfish is packaged.

S4, cleaning operation: after the crayfish finishes in grades, water jet 41 begins to spray water to the water column washes the inside screening frame 20 of processing operation frame 1, makes the hot water juice of its inside remaining supplementary condiment wash and collect in collecting box 314, guarantees the clean and tidy nature of whole device, collects the operation to wasing produced sewage at last.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
