PURPOSE:To eliminate the residue of pulverulent bodies unscraped by a scraper for preventing a hopper portion from packing by forming a connection from a bottom wall in a slant side wall of a hopper into a vertical wall to which is opposed an end of the scraper. CONSTITUTION:A connection from a bottom wall 1b in a slant side wall 1a of a hopper is formed into a vertical wall 10 to which an end of a scraper 8 is closely opposed. Thus, by the rotation of the scraper 8 can be efficiently discharged from an opening of the bottom wall 1b even pulverulent bodies different to discharge near the side wall 1a by the end of the scraper 8 close to the vertical wall 10 of the side wall 1a. Thus, the residue of the pulverulent bodies unscraped by the scraper can be eliminated for preventing the hopper portion from packing due to the stick of the remaining pulverulent bodies. |
