After the sweet potatoes in the peeling box 31 are soaked in hot water, the skin is more easily scraped off. After scraping, the sealing plate 311 sealed by the rubber sealing ring 312 is pulled outwards to discharge the sweet potatoes and the skin water mixture from the discharge hole on the front side of the peeling box 31 and into the collection box 41. The skin water mixture falls into the skin water collection box 44 through the gap between the inclined rods 43 in the inclined groove 42 and is collected, and the clean sweet potatoes are collected in the collection box 41. Subsequently, the skin water mixture in the skin water collection box 44 is discharged through the drain 45. When the steel wire mesh sleeve 39 is stuck with sweet potato skin due to the scraping of the sweet potato, the peeling rod 37 and the two L-shaped lifting rods 38 are separated by directly pulling the peeling rod 37 upwards, so that the steel wire mesh sleeve 39 is cleaned. When installing, the two limiting blocks 372 on the left and right sides of the plug rod 371 are aligned with the limiting grooves 362 on both sides of the plug groove 361 to be clamped in, so that the connecting rod 36 continues to drive the peeling rod 37 to rotate.
