The prawns in the peeling area 318 are simultaneously rubbed and kneaded by the peeling roller 323 and the wheel disc 312 against the shrimp shell, and the shrimp shell and the shrimp meat are gradually separated. In the process of shelling the prawns, the wheel disc 312 gradually rotates for a shelling stroke, namely the wheel disc 312 rotates for an angle of theta degrees, the shelled shrimps after shelling then fall into the kernel discharging area 319 under the rotation of the wheel disc 312, and then the shelled shrimps directly fall into the shelled shrimp collecting hopper 43. The dried small shrimps gradually enter the gap between the peeling roller 323 and the surface of the wheel disc 312 and gradually move to the rear of the peeling roller 323 along with the rotation of the wheel disc 312. The dried small shrimps are swept out of the wheel disc 312 by the rotating force of the brush roller 41 to the outside of the wheel disc 312 and fall into the corresponding dried small shrimp discharge pipe 44, and then discharged along the dried small shrimp discharge pipe 44. The four prawns in the previous round complete the husking process, and the material separating roller 22 continues to rotate to enter the next round of husking circulation.
The invention has simple structure and high shelling efficiency, and can realize the working procedures of distribution, shelling, separation and collection of prawns in a completely mechanized manner.
