It is mainly composed of hoist structure, steel wire rope, rake bucket, steel wire rope pulley, rake bucket elongation device, mechanical torque protection, motion drive, ground fixed track and mobile drive positioning device. The positioning and cleaning function of the whole machine, the lifting of the rake bucket, the opening and closing of the rake bucket dirt, and the scraping of the rake bucket dirt are the same as that of the fixed installation of the steel wire rope traction rake bucket grid decontamination machine, only the shelf is separated from the shelf, and the upper frame is all set on the moving drive. When decontamination is controlled with a stroke switch, the rack can be moved to the grille location where decontamination is required. When the upper and lower rack alignment is accurate, the rake can be successfully decontamination. For wide grids, the decontamination machine moves the effective width of the tooth rake and continues decontamination until the dirt on the surface of the grid is removed and the water level difference between the front and back of the grid reaches a normal value. For multi-channel distributed grilles, after decontamination of one ditch grille, the decontamination machine moves to another ditch and continues to decontaminate until the dirt on the surface of all ditch grilles is cleaned and the water level difference before and after the gate reaches a normal value.

6. The open structure makes the working platform clean and the working environment good;
7. Wide range of application, especially suitable for multi-channel or wide channel grid slag removal.
