PROBLEM TO BE SOLVED: To make a rake small-sized and lightweight and to shorten an operation route of the rake.SOLUTION: In a mono-rake dust remover 1, a rake 3 is lifted/lowered by a lifting/lowering mechanism 5, and dust 11 in water collected by a screen 2 is scraped up. The scraped dust 11 is discharged from an upper side to a collection mechanism 4. The lifting/lowering mechanism 5 includes: right and left conveyer chains 50 tensioned between a driving wheel 51 and a driven wheel 52 in an endless state; right and left guide rails 8; and a driving device 7 for driving the driving wheel 51. A proximal end portion of the rake 3 is connected to the right and left conveyer chains 50 and at an intermediate position between right and left arms 31, a guide roller 32 is provided which is rolled along each of guide rails 8. A lower end portion of each of the guide rails 8 protrudes from the driven wheel 52 and is bent closer to the screen 2 at an intermediate position of that protruding portion. An upper end portion of each of the guide rail 8 is bent towards a side of the collection mechanism 4 at an upper position of the collection mechanism 4. |
