Feed material handling apparatus |
摘要 |
The feed material handling apparatus has a frame supporting a feed-receiving hopper disposed horizontally on said frame and an impeller rotatable about a vertical axis therein impels said material through a discharge tunnel to a substantially vertical blower having an impeller operable about a horizontal axis which urges the material up a vertical transition member into a silo or the like. The hopper adjacent said tunnel is partially covered and provided with air inlet openings, while the sidewalls of said blower are imperforate except for a material inlet opening from said tunnel and openings for a shaft for said impeller of said blower. A metering blade also is mounted adjacent the inlet to said tunnel to control the flow of material to said tunnel.
