Detailed Description

The invention will be described in further detail with reference to the following detailed description.

As shown in fig. 1, the rotating shaft 9 is disposed below the frame 15 and rotatably mounted at the bottom of the frame 15. The compression roller body 1 is arranged on the rotating shaft 9 and driven to rotate by the rotating shaft 9. The peripheries of the left end face and the right end face of the compression roller body 1 respectively extend axially to form two annular frames 6, and the two annular frames 6 and the two end faces of the compression roller body 1 respectively enclose two asphalt temporary storage cavities 7. The end walls of the ends of the two annular frames 6 are slope surfaces 8, and the slope surfaces 8 gradually incline towards the direction of the roller body 1 from the outer frame wall 13 to the inner frame wall 14 of the annular frames 6. The left side of the left annular frame 6 and the right side of the right annular frame 6 are respectively provided with two square side baffles 2, the two side baffles 2 are respectively fixedly connected with two ends of the bottom of the frame 15, the back surfaces of the two side baffles 2 are respectively provided with two wear-resistant sealing rings 17 (see fig. 5), and the two side baffles 2 tightly cling to the tail end edges of the corresponding annular frames 6 through the respective wear-resistant sealing rings 17 so as to respectively seal the mouth parts of the two annular frames 6. As shown in fig. 5, the bottoms of the back walls of the two side dams 2 are partially recessed towards the front wall of the side dam 2 to form a vertical recycling channel 10, and the top end of the recycling channel 10 is bent to penetrate out of the side dam 2 and is communicated with the asphalt temporary storage cavity 7 of the annular frame 6. The bottom of every 2 positive walls of side shield has all been seted up vertical and has been put board groove 5, and the notch that puts board groove 5 is vertical down, and 4 tops of spring are installed on putting 5 interior roof walls of board groove, and perpendicular steel sheet 3 is installed and is being put 5 bottom of connecting spring 4 of board groove. As shown in fig. 3, the bottom edge of the vertical steel plate 3 is sharp, both bottom corners are rounded corners 12, and the edges of the rounded corners 12 are provided with wear pads (not shown in the figure).

As shown in figure 1, the roller travels on a solid road surface 16, the roller body 1 contacts the solid road surface 16, and the vertical steel plate 3 is driven by the spring 4 to extend downwards until being blocked by the solid road surface 16. On road roller marched the pitch layer 11 of town road, as shown in fig. 2, erect steel sheet 3 and driven by spring 4 and move down, insert unset pitch layer 11 through sharp bottom and block until by solid road surface 16 of pitch layer 11 below, thereby the compression roller body 1 is advanced by the drive of pivot 9 and is flattened pitch layer 11, thereby unnecessary pitch on the pitch layer 11 is crowded to two and is erected steel sheet 3 by compression roller body 1, thereby it blocks and enters into the pitch through recovery channel 10 and keeps in the chamber 7 to erect steel sheet 3. When the road roller meets the asphalt layer 11 which needs to be supplemented with asphalt, the asphalt temporarily stored in the asphalt temporarily storage cavity 7 of the annular frame 6 slides down the slope 8 of the annular frame 6 under the action of self gravity to the recovery channel 10 to be supplemented with the asphalt layer 11, so that automatic material supplement is realized. When the roller has pressed the asphalt layer 11 back onto the solid pavement 16, as shown in fig. 3, the front of the roller is tilted forward away from the asphalt layer 11 so that the leading rounded corners 12 of the vertical steel plates 3 are blocked by the solid pavement 16, and as the front of the roller continues to tilt forward, the vertical steel plates 3 of fig. 3 compress the springs 4 and retract into the slab-placing grooves 5 (not shown) as shown in fig. 4.

The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The person skilled in the art can make insubstantial changes or substitutions on the basis of the invention, and still fall within the scope of patent protection.
