The格栅CleaningMachineis composed of a drive unit, frame, main shaft, grating bars, slag tray, toothed scraper, and traction chain. Under the power of the motor, after being reduced in speed by the reducer, it drives the sprocket and chain to move. The cleaning toothed scraper chain fixed on the rotating chain moves to the bottom behind the grating. After passing through guide wheels, it flips to the front of the grating facing the water surface and continues to move into the gaps between the fixed grating bars, lifting the intercepted dirt from the front of the grating out of the water. The dirt is then automatically flipped and unloaded into the conveyor belt or slag bucket behind the grating, completing the cleaning process. Meanwhile, the liquid passes through the gaps between the grating bars. The entire operation runs in a continuous, cyclic state.
