Abstract
A pin conveyor for pasty materials such as animal waste including a housing with a cylindrical inner surface extending along and about an axis. Within the housing surface, a shaft is mounted for rotation about the axis and has a plurality of pins attached to it in a substantially helical pattern. The pins have sleeve members slidably mounted about them wherein in operation, the sleeve members are centrifugally impelled outwardly of the pins to contact and scrape clean the housing surface as the shaft is rotated about the axis. The cylindrical outer surfaces of the sleeve members preferably overlap or are at least tangent to one another when viewed in a plane perpendicular to the rotational axis so as to effectively contact and scrape clean the entire housing surface surrounding them.
