During operation, the dirt is transported backward from the front side of the grille 1, and the dirt is intercepted by the grille 1. At the same time, the reducer is started to rotate the main shaft 3, and the overload protection device 6 is used to ensure that the reduction motor 5 runs within the allowable torque. The rotation of the main shaft 3 drives the sprocket to rotate, thereby moving the chain 7. The movement of the chain 7 drives the cleaning rake 4 to move synchronously, so that the cleaning rake 4 removes the dirt intercepted on the grille 1 and collects it. When the cleaning rake 4 moves to the upper frame 2, the dirt collected in the cleaning rake 4 is discharged by its own gravity. Here, because the cleaning rake 4 is at the front side of the grille 1, the grille 1 can directly extend to the bottom of the orifice 13, and there is no gap between the bottom of the orifice 13 and the grille 1, thereby improving the dirt interception effect;
