PURPOSE:To promote efficiency in construction and repair work of a scraper, by setting up the supporting body of a rotatable scraping blade in a way being integrated with a rotary table, while installing the plural number of fixed blades on the table upward in a circumferential direction and thereby simplifying a circumferential rotation driving system in structure. CONSTITUTION:When a rotary table 14 is circumferentially rotated by a motor 13 at a set speed and moved in an arrow direction, a moving blade 7 cuts into granular contents 5 such as coal and the like through a slit 4 and meets with resistance with which it rotates and scrapes the contents 5 out of the container by a fixed amount step by step, dropping them on the rotary table 14. The scraped granular substance 5' is heaped up as a mound just under the moving blade 7 on the rotary table 14 but in keeping with the circumferential rotary motion, a heap of the granular substance 5' successively hits on each of fixed blades 22 whereby it is scraped and leveled out. A portion for the scraped is progressively fed to the rearmost position, leveling down to the heap of the granular substance 5' on the rotary table 14 and increasing it lengthwise. The granular substance 5' reaches a scraper 15, which scrapes it away onto a conveyor 16, and is reloaded on the conveyor 16 and carried out therefrom. |
