The block-supporting wall part (3a) is placeable at an angle in relation to the ground beneath it. Another wall part supporting the block is hinged in its connection to the wall part incorporating the scraping devices (4). The scraping devices are formed by an endless belt or chain (7) on which scraping components (8) are fixed. The scraping components (4) are L-shaped strips. The wall part supporting the block incorporates devices for downwards checking of scraped material (1), such as a plate positioned directly beneath the scraping components. In the outflow aperture (5) are devices for turning and tossing. |
