Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Fig. 1,2,3,4,5, the loose rake device on flexible pavement circular regeneration paver, comprises paver frame 5, longitudinal spacing mechanism, raking claw machinery, rake pawl rotational fuel tank 4 and rake pawl hoist cylinder 2.Described longitudinal spacing mechanism, rake pawl rotational fuel tank and rake pawl hoist cylinder are respectively two groups, are separately positioned on the two ends, left and right of rake pawl girder.
Described raking claw machinery is flexible raking claw machinery, comprise rake pawl girder 1, left rake claw-plate 3, right rake claw plate and transversal stretching oil cylinder 1-3, rake pawl girder arranges longitudinally through slideway 1-4, and the upper beam of left rake claw-plate and right rake claw plate is set in the slideway of rake pawl girder.Rake pawl girder is provided with the cavity at through two ends, and transversal stretching oil cylinder 1-3 is placed in cavity, and cylinder body is fixed in the middle part of rake pawl girder beam body, and cylinder bar is hinged with the upper beam of left rake claw-plate and right rake claw plate respectively.Moved laterally by the driving of transversal stretching oil cylinder 1-3, left rake claw-plate 3, right rake claw plate are moved along the slideway 1-4 left and right directions of girder, complete rake pawl width and change.
