A traveling direction of a sludge drawing tool can be reversed regardless of the position of the sludge drawing tool. An endless chain is wound around a pair of wheels, and has straight lines Land Lextending therebetween, and a pulling portion is provided in a part thereof. A sludge drawing tool is arranged to be able to move forward between the wheels. The sludge drawing tool is provided with engagement portions having a shape enabling the pulling portion circumferentially moving along the chain to be engaged therewith and disengaged therefrom. When the driving wheel rotates in a forward direction, the engagement portion comes into contact with the pulling portion circumferentially moving along the straight line Lin a drawing direction, to make the sludge drawing tool move in the drawing direction. During the rotation in the forward direction, the engagement portion comes into contact with the pulling portion.
