Laitance removing device suitable for semi-flexible pavement
The invention discloses a laitance removing device suitable for a semi-flexible pavement. The laitance removing device comprises a rack and an air blower. The rack comprises a rectangular frame. Two supporting rods extend downwards vertically from the front ends of the two sides of the rectangular frame respectively. A scraper beam close to the ground is arranged between the two supporting rods. The lower portions of the two supporting rods are each provided with a baffle beam. The two baffle beams extend to the front portions of the two sides of the rectangular frame respectively and the tail ends of the baffle beams are each provided with a guide wheel borne on the pavement. A rubber baffle is arranged below each baffle beam. A laitance scraper is arranged on the rear side face of the scraper beam. The bottom of the laitance scraper is tightly attached to the pavement and the laitance scraper is provided with a slope extending from the rear edge of the upper surface of the scraper beam to the position, behind the scraper beam, of the pavement. The air blower is arranged on the rectangular frame, an exhaust duct of the air blower extends obliquely to the position, behind the slope on the laitance scraper, of the pavement and to the position close to the lower edge of the slope, and the tail end of the exhaust duct is parallel to the laitance scraper.
