Problems solved by technology

[0002] For the maintenance of highway asphalt pavement, the existing method is to use the mechanical arm mechanism to drive the saw blade to cut the road surface, and then use the spatula on the mechanical arm to scoop up the waste asphalt and transport it to the recovery box on the construction vehicle. Compared with traditional manual excavation, the labor load of workers is reduced, but it requires the user to manipulate the mechanical arm for construction. The operation is cumbersome and inefficient during the construction process, and the professional requirements for workers who use the mechanical arm are high.
[0003] When the blade scoops up the waste asphalt, the waste asphalt on the front side of the blade is squeezed by the blade and gathers and overflows into the cutting groove, which still requires workers to clean up the spilled asphalt, which aggravates the labor burden; at the same time, The existing waste asphalt removal device usually integrates waste asphalt cutting and waste asphalt recycling. Although the waste asphalt treatment process is integrated, the car body is also made longer, which is not conducive to the traveling and turning of the car body.

Abstract

The invention discloses a waste asphalt removing device for highway construction. The waste asphalt removing device for highway construction comprises a vehicle body, wherein a movable frame is hinged to the vehicle body in a limiting mode; a transverse plate is vertically connected to the movable frame in a sliding mode; a vertical supporting column is fixed to the lower end of the transverse plate; a vertical supporting shaft is movably connected to the lower end of the supporting column; a connecting frame is fixed to the supporting shaft; cutting devices oppositely arranged on the front side and the rear side of the movable frame are connected to the connecting frame; each cutting device comprises a reciprocating lead screw rotationally connected to the connecting frame and transversely arranged; a sliding block transversely and slidably connected to the connecting frame is in spiral transmission on each reciprocating lead screw; a gear with an axis arranged in a front-back direction is rotationally connected to each sliding block; each gear is meshed with a transversely-arranged rack fixed to the connecting frame; each gear is coaxially and fixedly connected with a saw blade; the two reciprocating lead screws are driven by a first power device installed on the connecting frame; the supporting shaft is driven by a second power device installed on the transverse plate, so the supporting shaft stops after rotating by 90 degrees; and a third power device is arranged between and connected with the transverse plate and the vehicle body.
