Highway maintenance macadam homogenizing and spreading device

The utility model relates to the field of road maintenance, and particularly discloses an expressway maintenance broken stone homogenizing and spreading device which comprises a feeding port, a speedreducing plate is installed in the feeding port, a sliding groove is formed in the lower surface of a mounting flat plate, a sliding block is installed at the joint of the sliding groove and the mounting flat plate, and feeding ports are formed in the two ends of the sliding groove. A feeding groove is formed in the lower end of the material groove, the bottom end of the feeding groove is connected with flattening teeth, and an elastic rotating shaft is installed at the joint of the speed reducing plate and the bracket. The speed reducing plate and the feeding port rotate through the elastic rotating shaft, the situation that broken stones fall down rapidly and are accumulated in the trough, and the stone distribution efficiency is influenced can be effectively avoided, the spiral feedingmode can relatively guaran
