[0036] Specifically, the working principle of the road paving roller is as follows: when in use, the two ends of the front part of the connecting frame 121 are pinned to the rear of the tractor through the locking seat 151, and the locking seat 151 drags the pull rope 130 through the double ear seat 152. By pinning the four corners of the two mounting plates 141, it is convenient for the pull rope 130 to drive the truss shaft frame 310, the outer guide roller 410 and the inner guide roller 420 to assist in steering. The vertical degree of freedom between the connecting frame 121 and the second transverse connecting plate 122 is small, and the first longitudinal pin plate 113 and the second longitudinal pin plate 114 are connected. The plates 123 are pinned horizontally, and the first longitudinal pinned plate 113 swings upward and is blocked by the upper limit plate 124 of the second longitudinal pinned plate 123, and the first longitudinal pinned plate 113 swings downward and is blocked by the lower limit plate 124 of the second longitudinal pinned plate 123, so that the first longitudinal pinned plate 113 swings up and down with a certain degree of freedom, 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 appear in the venue, and the two pull rods 111 and the pull rope 130 pull the mounting seat 14 0, the mounting seat 140 drags the cross beam 210 and the fixed connecting beam 220 through the pin-joined ear 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 and drag the folding road surface on the shallows for paving, the end of the folding road surface is pulled out by the traction belt, and the guide groove 430 provides a guide for the traction belt. The guide limiter guides the folding road surface to the shallows from the upper side of the outer guide roller 410 and the inner guide roller 420, and the upper folding road surface is pressed on the laid folding road surface. The uninflated airbag is wound on the cylinder formed by the semicircular follow-up roller 510. As the wound airbag is released, the cylinder formed by the semicircular follow-up roller 510 rotates on the outer wall of the support cylinder 330 through the roller 540, and the released airbag is inflated by inflation. The inflated airbag is located between the upper folding road surface and the laid folding road surface, and the resistance of dragging the upper road surface is reduced by the airbag.

[0037] After the road paving roller is used, the connecting pins of the two mounting plates 141 and the pin-joined ear plates 250 are released, and the pin-joined ear plates 250 are pulled out from between the two mounting plates 141. The two pin-joined ear plates 250 at both ends of the rear of the mounting plate 141 are pulled out, and the connection between the mounting plate 141 and the pin-joined ear plates 250 is released, so that the connecting frame assembly 100 is removed from the mounting frame assembly 200, reducing the width required for shipping the road paving roller, improving the problem of the large space occupied by the overall shipping, facilitating transportation by vehicle, and making the transportation of the road paving roller meet the requirements of the transportation boundary. When releasing the connection between the fixed connecting beam 220 and the swinging beam 230, the double pin shaft connecting the side reinforcement ring 234 and the connecting tube 223 is pulled out, and then the positioning connecting frame 222 is pulled out from the positioning groove 232, so that the connection between the fixed connecting beam 221 and the swinging beam 231 is released, thereby further reducing the width required for the road paving roller shipment, improving the problem of the large space occupied by the overall shipment, facilitating transportation by vehicle, and enabling the road paving roller transportation to meet the transportation boundary requirements.
