Embodiment Construction

[0030] Such as figure 1 and figure 2 The shown anti-push extrusion road machine includes a frame 1 and a main compacting wheel 3 rotatably connected to the frame 1. Both sides of the main compacting wheel 3 are provided with connecting plates 14, and the main compacting wheel 3 The front of the solid wheel 3 is provided with an initial compaction wheel 10, and both sides of the initial compaction wheel 10 are provided with connectors 2 11, and the connectors 2 11 on both sides of the initial compaction wheel 10 are connected with the main compaction wheel 3. The connecting plates 14 on both sides are connected one by one. The main compacting wheel 3 is equipped with a crawler belt 6 that is wound on the primary compacting wheel 10 and is used to drive the primary compacting wheel 10 to rotate. The primary compacting wheel 10 A belt adjustment wheel 13 for adjusting the angle between the crawler belt 6 and the contact surface of the asphalt mixture is provided above the side ...

Abstract

The invention discloses an anti-push road roller which comprises a frame and a main compaction wheel which is rotationally connected to the frame, wherein two sides of the main compaction wheel are provided with connecting plates; a primary compaction wheel is arranged in front of the main compaction wheel; second connecting pieces are arranged on two sides of the primary compaction wheel; the second connecting pieces on two sides of the primary compaction wheel are correspondingly connected with the connecting plates on two sides of the main compaction wheel one by one; a track which is wound on the primary compaction wheel and is used for driving the primary compaction wheel to rotate is arranged on the main compaction wheel; a track adjusting wheel used for adjusting the included angle between the contact surface of the track and the bituminous mixture is arranged on the lateral upper part of the primary compaction wheel; two sides of the track adjusting wheel are provided with first connecting pieces; the first connecting pieces on the two sides of the track adjusting wheel are correspondingly connected with the connecting plates on two sides of the main compaction wheel one by one; and wheel teeth meshed with the track are formed in the main compaction wheel, the primary compaction wheel and the track adjusting wheel. According to the anti-push road roller, the rolling rack can be avoided, the rolling quality of the bituminous mixture is improved, and the road roller is simple in structure and convenient to popularize and apply.

Description

technical field [0001] The invention relates to a road roller, in particular to an anti-push extrusion road machine. Background technique [0002] When the traditional steel wheel roller is performing the initial pressing of asphalt mixture, due to the linear contact between the steel wheel and the mixture, the contact pressure is high, and the temperature of the newly laid asphalt mixture is high and the state is loose, which often causes the mixture to push and bulge. In addition, excessive linear pressure can easily cause cracks in the asphalt mixture during the rolling process, and even break the exposed aggregate. Therefore, the use of steel wheel rollers cannot guarantee the smoothness of the road surface, and the performance of the mixture is poor. At the same time, the analysis of the compaction principle of asphalt mixture found that there are defects in evaluating the compaction of asphalt mixture only by evaluating the compaction of free granular materials, while...
