DRIVE-AWAY DEVICE FOR OUTER CIRCUMFERENCE TAKE-OUT TYPE SILO

PURPOSE:To save a wasteful power consumption enabling maintenance operations to be easily accomplished by arranging a feed groove which is concentric with a silo, on the outer circumference of the silo at its bottom surface while a ring girder is installed on the upper side of the groove where a scraping blade and a scraper are arranged. CONSTITUTION:A ring girder 25a is allowed to rotate at the desired speed to the stated direction by a driving means, this allows a take-out blade 25b to scrape out a heap of stored particle materials such as coals, which slips out to the silo bottom surface through gaps 18, down to a feed groove 32 while the materials are demolished. On the other hand, a scraper 25b' moves along the feed groove 32 as an integral unit with the ring girder 25a, and permits the stored particle materials 20, which have been scraped out down to the feed groove 32, to be transferred while they are dipped up allowing them to be driven away finally from a take-out outlet 32. Thus, a drive-away device is arranged completely on the outer circumference of the silo, therefore, the device is not subjected to any load from the weight of the stored particle materials 20 allowing the device to operate under the lighter condition by that much. In addition, an ample space is provided enabling maintenance operations to be easily accomplished.
