PURPOSE: A scraper of a reclaimer wheel bucket is provided to remove the ore stuck onto a wheel bucket by making a scraper move along the inner face of the wheel bucket with a scraping plate attached to the lower end of an arm link member. CONSTITUTION: Arm guide plates are installed while rectangular portions are installed in the rotatably state. Supports are installed on a boom(140) not to interrupt a rib(110a) of a wheel bucket(110). A roller installed on the upper end of an arm link member is fitted to long holes. A hinge shaft is formed in the middle of a first link of the arm link member and rotatably connected to an upper hole of the arm guide plates. A scraping plate is mounted on the lower end of a second link. The scraping plate moves along the inside of the wheel bucket.
