[0046] Specifically, the working principle of the road paving roller: when in use, the two ends of the front part of the connecting frame 121 are pinned to the rear part of the towing vehicle through the locking seat 151, the locking seat 151 drags the pull rope 130 through the double lug seat 152, and the pull rope 130 is pinned through the four corners of the two mounting plates 141, so as to drive the truss shaft frame 310, the outer guide roller 410 and the inner guide roller 420 to assist in steering. The connecting frame 121 and the second transverse connecting plate 122 have small freedom in the vertical direction, the first longitudinal pin plate 113 and the second longitudinal pin plate 123 are transversely pinned, the first longitudinal pin plate 113 is blocked by the upper limiting plate 124 of the second longitudinal pin plate 123 when it swings upward, and the first longitudinal pin plate 113 is blocked by the lower limiting plate 124 of the second longitudinal pin plate 123 when it swings downward, so that the first longitudinal pin plate 113 has a certain freedom in swinging up and down, and the truss shaft frame 310, the outer guide roller 410 and the inner guide roller 420 can rise and fall to adapt to the uneven ground that may occur in the site. The two pull rods 111 and the pull rope 130 pull the mounting seat 140, the mounting seat 140 drags the cross beam 210 and the fixed connecting beam 220 through the pin lug plate 250, the fixed connecting beam 220 drives the swing beam 231 and the bearing seat 240, the bearing seat 240 pulls the shaft head 320, and then pulls the truss shaft frame 310, the truss shaft frame 310 rotates in the bearing seat 240 through the shaft head 320, the outer guide roller 410 and the inner guide roller 420 roll on the shoal to drag and pave the folded road surface, the end of the folded road surface is pulled out by the traction belt, and the guide groove 430 provides guidance and limiting for the traction belt. The folded road surface is guided from the upper side of the outer guide roller 410 and the inner guide roller 420 to the shoal, the upper folded road surface is pressed on the paved folded road surface, the uninflated air bag is wound on the cylinder body formed by the butt joint of the semi-circular follow-up winding drum 510, and as the wound air bag is released, the cylinder body formed by the butt joint of the semi-circular follow-up winding drum 510 rotates on the outer wall of the supporting cylinder 330 through the roller 540, the released air bag is inflated, and the inflated air bag is located between the upper folded road surface and the paved folded road surface, and the air bag reduces the resistance of dragging the upper road surface.

[0047] When the road paving roller is used, the connecting pin shafts of the two mounting plates 141 and the pin joint ear plates 250 are removed, the pin joint ear plates 250 are pulled out from between the two mounting plates 141, the two pin joint ear plates 250 at the two ends of the rear of the mounting plate 141 are pulled out, the connection of the mounting plate 141 and the pin joint ear plate 250 is removed, and thus the connecting frame assembly 100 is detached from the mounting frame assembly 200, the width required for the road paving roller to be shipped is reduced, the problem that the space occupied by the whole shipment is large is improved, the road paving roller is conveniently transferred by vehicle, and the transportation of the road paving roller meets the transportation limit requirement. When the connection of the fixed connecting beam piece 220 and the swing beam piece 230 is removed, the double pin shafts connecting the side reinforcing ring 234 and the connecting cylinder 223 are pulled out, the positioning connecting frame 222 is pulled out from the positioning groove 232, the connection of the fixed connecting beam 221 and the swing beam 231 is removed, the width required for the road paving roller to be shipped is further reduced, the problem that the space occupied by the whole shipment is large is improved, the road paving roller is conveniently transferred by vehicle, and the transportation of the road paving roller meets the transportation limit requirement.
