CLEANING SCRAPER FOR GARDEN TOOL CUTTING EDGE Russian patent published in 2007 - IPC A01B1/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to garden tools, such as hand sacks, garden spades, axes, etc, and it is designed for cleaning tool cutting edges from sticky dirt, gum, etc. proposed scraper contains working part with contact flanges narrowing in direction to ring holder for pin, and contact flat for tool cutting edge. Scraper has one working part made integral with holder from one common flat blank so that contact flanges of working part of length μ from side of one end face of blank form acute angle α in between of plane of cutting edge, and they are widened in direction to holder by its width ρ. Other end of blank bent into holder ring is provided with flat part which has separate detachably connected contact flat from side of flanges forming angle β with contact plane of flanges. Flanges if section of working part are bent towards tool cutting edge through obtuse angle γ. Cleaning scraper is detachably pressed to tool shank by means tension ring.

EFFECT: facilitated manufacturing of cleaning scraper, reduced material usage, making scraper universal and compatible with other tools, facilitated connection with wooden or other shanks of tool, provision of safety.
