Zusammenfassung:	The utility model relates to a wear-resisting hopper which is mainly used for supplying raw materials for a puddling blast furnace, comprising a hopper, the inner wall of which is fixedly provided with a plurality of knockout devices. The utility model is characterized in that the knockout device is a closed box with two sides taking the shape of triangles. The utility model is simple in structure, convenient for replacement, high in wear and impact resistance. The test made by an iron mill of coking plant of Shanxi Taigang Stainless Steel Co., Ltd. shows that the wear-resisting hopper has the service life of over 6 months (the existing hopper has the service life of 2 to 3 months) and prevents the knockout devices from abscission.
