The invention relates to a ramie scraping mechanism for a whole-stalk type ramie fiber primary processing machine. The ramie scraping mechanism is arranged on the rear inner faces of the ramie retaining rods of the whole whole-stalk type ramie fiber primary processing machine and on the front portions of the left side and the right side of clamp traction bodies and comprises two groups of front-back ramie scrapers which are arranged in a left-right symmetry manner, and the two groups of ramie scrapers comprise four ramie scrapers, each ramie scraper comprises a fixed blade, a movable blade andcompression springs, each ramie scraper tilts 20 degrees forwardly and 45 degrees inwardly, the cutting edge of each movable blade extends out 1-2mm to press on the cutting edge of the correspondingfixed blade, the included angle between each movable blade and the corresponding fixed blade is 90 degrees, each movable blade and the corresponding fixed blade are compressed by the compression springs, the cutter point section sharp corner of each blade is 30 degrees, and the fillet radius of each blade is 0.5mm. The ramie scraping mechanism has the advantages that the openings of the ramie scrapers aim at clamp traction lines, and ramie shell surface skin on ramie bark can be completely scraped during peeling to complete primary processing to obtain fresh fibers.
