The utility model relates to a spring buffer roller set, comprising a buffer supporting roller, a supporting roller frame, an inner slideway, an outer slideway, a double headed bolt, a spring and a soleplate. The two inner slideway is symmetrically arranged on the left and the right sides of the bottom of the cross beam of the roller support, the upper end of which is welded at the bottom of the cross beam, and the lower part is embedded in the outer slideway to slide up and down. The spring is vertically arranged between the inner and outer slideway, and is sheathed on the stud. The double headed bolt passes through the hollow part of the spring, and the upper end of the stud bolt is fixedly connected with the inner slideway through the nut, and the lower end of the bolt passes through the outer slideway. The bottom plate is connected by a bottom nut through a single nut, and the three are combined into a whole to form a spring device. The utility model is used for the blanking section of a belt conveyor in mines, docks, metallurgy, etc. the utility model can be used in a single group or in a plurality of groups to be installed side by side to form a buffer bed. By adding a spring device in the buffer roller set, the elasticity and buffering stroke are increased, and the resistance between the adhesive tape and the adhesive tape is reduced, and the impact damage of the rubber belt is effectively reduced when the material falls.
