Examples

As shown in fig. 1-3, the utility model provides a high efficiency leveling device of asphalt paving machine, including paver frame 1, the bottom of paver frame 1 is provided with track removal structure 2, levels device 3 and pitch discharge gate 4, the top of paver frame 1 is provided with pitch pan feeding funnel 5, be provided with heating chamber 6 between pitch pan feeding funnel 5 and the pitch discharge gate 4, one side of pitch pan feeding funnel 5 is provided with control chamber 7, level device 3 including fix at the support 8 of paver frame 1 and with the roller 9 that support 8 cup jointed mutually, level and be provided with compaction device 10 between device 3 and the pitch discharge gate 4.

Asphalt enters a heating chamber 6 through an asphalt feeding funnel 5 to be heated, flows out from an asphalt discharge port 4 after being heated, is compacted by a compacting device 10, is flattened by a flattening device 3, can remove bubbles in the asphalt, is flattened by a roller 9 of the flattening device 3, can greatly improve the flatness of the asphalt, the compacting device 10 comprises a supporting point 11 and a hydraulic driver 12 which are fixed on a paver frame 1, a pressing plate 13 is arranged between the hydraulic driver 12 and the supporting point 11, a fixed rod 14 is arranged on the pressing plate 13, a piston rod 15 is arranged in the hydraulic driver 12, the piston rod 15 is connected with the fixed rod 14 through a crank 16, the supporting point 11 is connected with the fixed rod 14 through a connecting rod 17, and the piston rod 15 is driven to move through the hydraulic driver 12, the piston rod 15 moves and is transmitted to the fixed rod 14 through the crank 16, so that the fixed rod 14 moves, the fixed rod 14 is connected with the supporting point 11 fixed on the paver frame 1 through the connecting rod 17, the fixed rod 14 moves in an arc-shaped track with the supporting point 11 as the center, and the pressing plate 13 fixed with the fixed rod 14 can be extruded up and down.

Considering the moving track of the fixed rod 14 as moving up and down and moving horizontally at the same time, in order to ensure the effect of asphalt compaction and improve the flatness of the whole, the horizontal moving speed of the pressing plate 13 is the same as the moving speed of the caterpillar moving structure 2, as shown in fig. 3, when the spreading machine moves, the pressing plate 13 moves horizontally and backwards and moves downwards at the same time, because the horizontal moving speed of the pressing plate 13 is the same as the moving speed of the caterpillar moving structure 2, relative to asphalt, the pressing plate 13 only moves downwards to extrude the asphalt, the pressing plate 13 moves downwards and backwards first, and then when the pressing plate 13 is located at the bottom end, the pressing plate 13 starts to move upwards and forwards, the movement is a period, in order to ensure that all asphalt is compacted, the pressing plate 13 must move after a moving period, the tail end of the pressing plate 13 moves to the front end of the pressing plate 13 before a moving period, this ensures that all of the asphalt is compacted, and therefore the maximum displacement of the horizontal movement of the platen 13 is 1/2 of the horizontal length of the platen 13, which allows all of the asphalt to be compacted and improves the flatness of the asphalt.

In order to prevent that pitch from there being pitch in compaction and smooth in-process to glue the condition emergence of gluing, all be provided with antiseized glutinous layer 18 at the surface of clamp plate 13 and roller 9, simultaneously, antiseized glutinous layer 18 adopts release agent or antiseized glutinous agent to paint and forms, and release agent or antiseized glutinous agent can avoid producing the influence to the purity of pitch in antiseized glutinous.
