description	The utility model belongs to the technical field of coal screening, and particularly relates to a raw coal grate bar screen buffer device. The invention aims to solve the problem that coal or gangue impacts a chute behind a grate bar screen, and especially the gangue with a large size impacts the chute, resulting in frequent welding of the chute. The buffer device comprises a first-stage buffer assembly and a second-stage buffer assembly, the first-level buffer assembly comprises a first portal frame and a rubber door curtain arranged on a body of the first-level buffer assembly. The second-level buffer assembly comprises a second portal frame and a plurality of chains evenly distributed on a body of the second portal frame. The first portal frame and the second portal frame stretch acrossthe grate bar screen, and the rubber door curtains and the chains are located between a left side plate and a right side plate of the grate bar screen. The device is simple in structure, easy to manufacture, low in cost and
