Description

Technical Field

[0001] This utility model relates to the field of crayfish cleaning equipment, and in particular to a crayfish pretreatment equipment. Background Technology

[0002] Crayfish are easily contaminated with mud, sand, impurities and other pollutants during growth, harvesting and transportation, which poses a potential safety hazard to subsequent cooking and consumption. Therefore, they need to be pre-treated before steaming or boiling, which includes two steps: soaking and washing.

[0003] The cleaning process typically employs a specialized cleaning device, which includes a horizontally rotating cleaning drum. During cleaning, crayfish are placed inside the drum, and the drum is driven to rotate. The bristles on the inner wall of the drum brush the outer wall of the crayfish. However, the bristles can only follow the drum in a circumferential rotation around the drum's axis. Within one rotation cycle, the brushing effect of the bristles on the crayfish's surface is limited, resulting in poor cleaning efficiency. Therefore, it is necessary to extend the cleaning time to ensure cleaning quality, but this significantly reduces cleaning efficiency. Utility Model Content

Several surrounding rods are arranged at equal angular intervals around the main rotating rod with the axis of the main rotating rod as the center. The two ends of the surrounding rods are rotatably connected to the two end rings respectively, and the bristles are fixed at equal intervals on the outer wall of the surrounding rods.

[0008] A synchronous rotation assembly is installed on the inner wall of the upper middle part of the frame to drive multiple rods to rotate simultaneously when the cleaning drum rotates to clean the crayfish.

[0009] Preferably, the distance between two adjacent said surrounding rods is less than the body width of the crayfish, the bristles on each surrounding rod are arranged in multiple groups along the axial direction of the surrounding rod at equal intervals, and each group of bristles is arranged at equal angular intervals with the axis of the surrounding rod as the center.

[0010] Preferably, the synchronous rotating assembly comprises two driven gears fixed symmetrically at the two ends of the surrounding rod, two gear rings are arranged symmetrically at the two ends of the cleaning drum, the two gear rings are fixed to the inner walls on both sides of the upper end of the rack respectively, and the two gear rings are located on the inner side of the cleaning tank.
