Bucket including blades provided with retractable scrapers

摘要

The drive unit i.e. blade (120) has a scraper (170) intended to avoid jamming of a material, likely to be contained in a bucket, between a peripheral edge (143) of the blade and a material retaining wall during rotation of the blade. The scraper is manufactured of an elastomer material that is less rigid than that of a part complementary to the blade, where the peripheral edge of the blade is delimited by a radius (O) centered on an axis of a shaft of a mixing and/or distribution system. The scraper includes a plate fixed on the blade via fittings (180). An independent claim is also included for a bucket.
