The telescopic soil covering device with the material shifting compression roller is characterized in that the left end and the right end of the telescopic material shifting compression roller (5) are hung on the front cross beam (21) of the telescopic frame on two sides of the telescopic frame (3) through a lifting mechanism (2); when the operation is needed, the telescopic material poking compression roller (5) falls to the ground through the lifting mechanism (2), so that the telescopic material poking compression roller (5) is in contact with the paving material to complete the widening operation, and the paving material can be paved; when not needing the operation, promote telescopic stirring material compression roller (5) through hoist mechanism (2) to articulate lifting bar (23) or articulate spindle nose (16) at telescopic stirring material compression roller (5) both ends through the couple, make telescopic stirring material compression roller (5) not contact with the stone.
3. A telescopic casing assembly with a kick-off roller according to claim 1, characterised in that the telescopic kick-off roller (5) is towed and rolled forward by a covering machine or tractor; in order to increase the rolling friction coefficient between the telescopic material poking press roller (5) and the ground, the fact that tooth-shaped structures are fixedly connected on the outer wall of the roller (13) or the side edges of the spiral blades (14) is not excluded.
4. The telescopic soil covering device with the material poking and pressing roller is characterized in that the depth limiting wheels (1) are fixedly connected to two sides of the telescopic rack (3) and extend and retract to two sides along with the telescopic rack (8); the soil covering device can adapt to the fluctuation of the ground in the operation process, and the height of the depth wheel (1) can be adjusted.
5. The telescopic soil covering device with the material shifting compression roller is characterized in that in the operation process of the telescopic material shifting compression roller (5), in order to prevent the material blocking phenomenon from occurring at the telescopic positions among the sections of the roller (13), the telescopic position among the sections of the roller (13) is not covered with a layer of telescopic elastic material to form sealing, and the telescopic material shifting compression roller is required to have certain strength and good wear resistance.
