Abstract:
A device for cleaning objects from a sewer pipeline comprising:a rotatable shaft having a longitudinal axis;a cutting member attached to said shaft, said cutting member having a plurality of substantially flexible cutting arms,wherein each of said plurality of cutting arms extend radially to said longitudinal axis of said shaft when rotated;wherein said cutting member is attached to said shaft by an attachment means which comprises an attachment member and at least one set bolt and nut, wherein said attachment member is attachable to said rotatable shaft with said at least one set bolt and nut; andmeans for rotating said shaft and said attached cutting member about said longitudinal axis of said shaft at a sufficient angular speed such that said plurality of cutting arms creates a cutting force for cutting an object from within an area through which said plurality of cutting arms circumscribes when said shaft is rotated, said area being substantially perpendicular to said longitudinal axis of said shaft.
