NOVELTY - The utility model claims a straw graphene pantograph, comprising arched bracket, the bracket is set on the upper surface of slide groove, the slide groove is set in the middle of the slide bar, bracket and slide through conductive adhesive, bracket is hollow; slide groove is set with multiple air passages connected with the bracket inside, airway set along the length direction of the bracket, bracket and lower surface is provided with multiple air holes connected with the bracket; the slide bar is rice and wheat straw graphene strip, strip lower surface provided with a corresponding passage of the mounting groove. on the slide surface is provided with a limiting groove. The utility model claims a straw graphene pantograph light weight, large hardness, excellent conductivity and abrasion resistance, and the performance index is better than the traditional pantograph carbon slide bar can make the electric traction locomotive operation and long service life; the main material from extracted from rice and wheat straws, manufacturing technique is simple and the production cost is low, so the agricultural waste can be recycled, the environment pollution is reduced.
