PURPOSE:To eliminate twist of a ling chain on the whole by suitably disposing a plurality of guide means having suitable cross-section in the interior of a pipe- type chain conveyer. CONSTITUTION:Guide means 12 formed in such a manner as to gradually project toward the center of a pipe 5 along the direction of the movement X of a link chain 6 are mounted at several places of a pipeline. When a blade 7 is driven to circulate at those places, the outer peripheral edge of the blade 7 is brought into contact with the guide means 12 to force the blade 7 to turn clockwise and counter-clockwise, whereby the blade is turned in the same direction as the link chain. The turning direction and turning angle are suitably combined to eliminate the twist of the link chain on the whole at the place of a driving roller. |
