Asphalt pavement hot in-place recycling anti-rut agent spreader

Abstract

The invention discloses an asphalt pavement hot in-place recycling anti-rut agent spreader which comprises a spreading hopper. The spreading hopper is strip-shaped; the bottom of the spreading hopper is provided with a strip discharge port; a spreading shaft is arranged at the discharge port; a rotor sleeve is assembled on the spreading shaft; a plurality of spreading grooves which are arranged in parallel to the axis direction are uniformly distributed on the face of the rotor sleeve or are uniformly distributed on the face of the rotor sleeve in a staggered manner; the diameter of the rotor sleeve is adaptive to the width of the discharge port; a friction wheel and chain wheel transmission mechanism is used as a driving mechanism for the spreading shaft. According to the invention, a spreading shaft, rotor sleeve and spreading groove structural manner is adopted; a friction tire rubs against the ground to obtain a driving force so as to drive the spreading shaft to rotate; an anti-rut agent is spread by a plurality of spreading grooves; the anti-rut agent is spread uniformly; moreover, the asphalt pavement hot in-place recycling anti-rut agent spreader has a simple structure, a power device does not need to be mounted, the asphalt pavement hot in-place recycling anti-rut agent spreader is energy-saving and environmental-friendly and the working efficiency is improved.

Description

technical field [0001] The invention relates to an in-situ thermally regenerated anti-rutting agent spreader for asphalt pavement, which is suitable for the field of large-scale thermally regenerated construction and maintenance technical equipment for asphalt pavement. Background technique [0002] Rutting is a unique form of damage to asphalt concrete pavement. It is a permanent deformation that cannot be recovered under the combined action of repeated driving loads and climate (high temperature). The generation of ruts not only affects the flatness of the road surface, but also reduces driving comfort; on road sections with large ruts, it is difficult to control the direction of the vehicle, and the road drainage is not smooth in rainy days, and the vehicle is prone to drifting, which seriously affects the service quality and quality of the road. The safety of driving directly affects the service life of the road surface, and brings many hazards to the asphalt pavemen...

Problems solved by technology

[0003] At present, the spreading method of anti-rutting agent in hot-in-place regeneration still adopts the method of manual spreading, and the spraying amount lacks uniformity and the manual work intensity is high, which will also cause certain damage to the body of the construction workers.

[0004] The Chinese invention patent application document "A Bulk Material Spreader" (publication number CN1255571A) discloses a bulk material spreader, which is a device designed for bulk materials. Because it uses spiral rollers to distribute material, it cannot be used Anti-rutting fabric, and requires energy-consuming power units to drive the spiral rollers
