A mechanical dust removing machine for sewage and drainage is provided to prevent relatively big obstacles such as timbers by installing an obstacle removing member at the end of a blocking plate. A mechanical dust removing machine for sewage and drainage comprises a rake unit(30), first and second positioning units(40,50), and first and second rotating units(70). The lake unit includes a plurality of rakes(31), which are lifted by a lift unit installed at front frames of a main screen. The lakes are arranged regularly to remove obstacles in water. The first positioning unit, which is installed at a main screen and the rake unit, rotates the rakes when the rake unit lifts in order to convey obstacles. The second positioning unit removes the obstacles caught at the main screen by the rakes when the rake unit lowers. The first rotating unit, which is installed at the top of the main screen or the guide frame, rotates the rake unit so that the rake unit can be moved by the second positioning unit. The second rotating unit, which is installed at the lower part of the main screen, rotates the rake unit so that the rake unit which is in a vertical position by the second positioning unit can collects the obstacles with the first positioning unit. |
