The invention relates to the technical field of mining mechanical equipment, in particular to an ore vibrating screen. The ore vibrating screen comprises a base plate and screen bars, wherein positioning holes are formed in the base plate, the screen bars are made of composite wear-resistant alloy through casting, the screen bars and the base plate are fixed through vacuum welding, and the screenbars are of isosceles trapezoid structures with upper edges longer than lower edges. The ore vibrating screen has the beneficial effects of long service life, specifically, a high-hardness wear-resistant alloy material is adopted, the wear-resistant life of the high-hardness wear-resistant alloy material is 5-10 times that of a common wear-resistant material; high efficiency, specifically, the stone clamping phenomenon in a using process of a traditional vibrating screen is basically eliminated, the operation load of vibrating equipment is reduced, daily maintenance of the vibrating equipmentis reduced, and the production efficiency is greatly improved; and high benefit, specifically, the abrasion of the vibrating screen is greatly reduced, the production cost of enterprises is directly reduced, meanwhile, maintenance personnel and maintenance frequency are reduced, the vibration maintenance management cost is reduced, and economic benefits are improved for the enterprises.
