Stone moving device for double tires of off-highway wide-body dumper

The utility model relates to a stone moving device for double tires of an off-highway wide-body dumper. The stone moving device is composed of a middle bridge tire stone moving mechanism and a rear bridge tire stone moving mechanism. The two stone moving mechanisms are each composed of a stone moving plate support, a front stone moving plate, an adjusting gasket and the like. Between each front stone moving plate and the corresponding stone moving plate support and between a rear stone moving plate and a stone moving plate stand, the gap between the side face of each front stone moving plate and one tire and the gap between the side face of each rear stone moving plate and the other tire are adjusted by adjusting the numbers of the adjusting gaskets on the left side and the right side of the front stone moving plate and the rear stone moving plate, so the front stone moving plate and the rear stone moving plate are hung right in the middles of the two tires. According to the stone moving device, stone clamped between the two tires is removed according to a lever principle, broken stone between the tires is automatically removed through rotation of the tires when the dumper is driven, the service life of the tires is effectively prolonged, and the time and labor for removing stone clamped between the tires manually are reduced.
