PROBLEM TO BE SOLVED: To provide a trash throwing-in machine for a screw conveyer largely inclined upward. SOLUTION: A spiral umbrella blade 3 is provided on a screw shaft 2 in a casing inclined forward and upward, an inclined cross sectional part 6 connecting a root part 4 and a rear tip part 5 in a vertical cross section of the umbrella blade 3, and a perpendicular line is drawn from the tip part 5 of the inclined part 6 to a screw shaft 2 to set an umbrella angleα7. A truncated cone shaped column is formed by putting an inclined plate around between a small circle and a large circle against the umbrella blade screw. COPYRIGHT: (C)2005,JPO&NCIPI
