Ramie scraping mechanism for whole-stalk type ramie fiber primary processing machine

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a mechanical device for bone-setting centralized preliminary processing of ramie fibers. Background technique [0002] Ramie is a unique traditional economic crop in my country. One of the current harvesting methods is to manually peel off the hemp skin from the hemp stalk in the field, and then remove the skin with a hemp scraper or machinery. The other is to first harvest it by workers or machinery. The hemp stalks are cut off, and then the hemp bone and epidermis are removed mechanically at one time. [0003] So far, the mechanized technology of primary processing of ramie fiber is still immature. Looking at the various types of power stripping machines, the labor intensity of manpower reverse pulling is high, the efficiency is low, the separation of skin and bone is not clear for direct feeding, and the structure of horizontal feeding is complicated , and all use...

Problems solved by technology

[0003] So far, the mechanized technology of primary processing of ramie fiber is still immature. Looking at the various types of power stripping machines currently available, the manual pull-back type has high labor intensity and low efficiency, the direct-feed type has unclear separation of skin and bone, and the horizontal-feed type has a complex and huge structure , and all use the rotating blade drum to crush the hemp bone, and then clean and separate to get the fiber

This bone-crushing processing method will more or less adhere some broken bones to the ramie fiber, that is, the bone-crushing processing method determines that the fiber has a relatively high bone content, and the broken bones on the fiber will affect the ramie textile. , a technical problem that is still difficult to solve so far, on the other hand, it is also not conducive to the effective utilization of bone marrow
