The utility model discloses an anti-skid wear material spreader for pavement maintenance, which relates to the technical field of pavement maintenance and comprises a transport vehicle, the top of the transport vehicle is rotatably connected with a carriage through a hinge, the bottom of the carriage is fixedly connected with a spreading pipe on one side of the transport vehicle, and the outer side of the spreading pipe is sleeved with a discharge pipe. The discharging pipe is rotationally connected with the spreading pipe, two adjusting plates are rotationally connected into the discharging pipe, and an adjuster is installed on one side of the discharging pipe. Compared with the prior art, the anti-skid wear material spreader for pavement maintenance has the beneficial effects that the rotary discharge pipe sleeved outside the spreading pipe is matched with the connection of one end of the adjusting rod on the turntable and the discharge pipe, so that the adjusting rod can drive the discharge pipe to swing repeatedly along with the rotation of the turntable, the discharge of materials is accelerated, the blockage is prevented, and the service life of the spreading pipe is prolonged. And the adjusting plate in the discharging pipe rotates under the action of the worm gear set and the worm set, so that the angle of the adjusting plate and the distance between one end of the adjusting plate are conveniently adjusted, and the discharging range is controlled.
