The present invention relates to a dusting machine without influence on water flow comprising: a frame which has a lower end submerged in a passage through which water flows and an upper end extending to the outside of the passage; a driving drum and a driven drum which are supported and installed on an upper end and a lower end of the frame to be rotatable and have sprocket wheels on outer circumferential surfaces on the both ends; screens which are placed on chain belts hung on the sprocket wheels of the driving drum and the driven drum and move in accordance with the rotation of the driving drum and the driven drum; a blocking unit which blocks the surrounding of the passage of the driven drum not to directly discharge water introduced into the front of the screen to the rear side of the driven drum; and a drainage pipe which is formed on a lower end of the frame and discharges water blocked by the blocking unit to a side of the driven drum by deviating the water. The dusting machine has an open structure of driven drum to make water except impurities to flow in from various directions of the driven drum, so that a bottleneck phenomenon is not caused despite an increase in water flow flowing along the passage. Therefore, the dusting machine can prevent overflow of water from a passage. |
