[0035] like Figure 1-7As shown, a connecting plate 303 is fixedly embedded inside the fixed block 2, and a gear 2 302 is movably embedded on one side of the outer surface of the connecting plate 303. The output end of the motor 304 is fixedly connected to one side of the outer surface of the gear 2 302, which can effectively utilize the device space. The rotation of the output end of the motor 304 drives the gear 2 302 to rotate.

[0036] like Figure 1-7 As shown, a gear 1 301 is movably embedded on one side of the outer surface of the connecting plate 303, and the outer surface of the gear 1 301 meshes with the outer surface of the gear 2 302, so that the gear 1 301 and the gear 2 302 rotate effectively. The rotation of the gear 2 302 drives the gear 1 301 to rotate, so that the fan 3 starts to rotate.

[0037] like Figure 1-7 As shown, a fan 3 is fixedly mounted on one end of the gear 1 301, which can effectively cool the asphalt concrete. The fan 3 starts to rotate and accelerates the cooling of the asphalt concrete in time.

[0038] like Figure 1-7 As shown, one end of the rotating rod 209 is fixedly connected to the cylinder 203, and a plurality of limiting posts 204 are fixedly installed on one side of the outer surface of the cylinder 203, which effectively limits the cylinder 203, and pushes the slider 207 so that the slider 207 is inserted between the limiting posts 204, thereby limiting the cylinder 203.

The force generated by the movement of the second pneumatic rod 105 drives the support rod 106 to move downward. As the roller body 1 moves, the roller 108 begins to fit the ground for timely re-pressing.

[0042] Working principle: when the staff is driving the roller body 1, he first turns on the external power supply of the first pneumatic rod 103, and then uses the controller to control the first pneumatic rod 103, so that the push rod of the first pneumatic rod 103 pushes the cross bar 104 to move. While the cross bar 104 moves, it drives the second pneumatic rod 105. The force generated by the movement of the second pneumatic rod 105 drives the support rod 106 to move downward, and the connecting rod 107 also moves downward with the movement of the support rod 106. The movement of the connecting rod 107 causes the roller 108 to gradually move to the asphalt concrete ground. As the roller body 1 moves, the roller 108 begins to fit the ground for timely re-pressing. In order to re-press and repair to the designated position, the staff first uses the controller to retract the push rod of the first pneumatic rod 103, thereby lifting the roller 108 as a whole. At this time, the staff turns on the external power supply of the second pneumatic rod 105, and uses the controller to make the push rod of the second pneumatic rod 105 push the support rod 106 to move. When the support rod 106 moves to the required position, the staff The controller is used to stop the second pneumatic rod 105. At this time, the staff lowers the roller 108 as a whole, so that the designated position can be re-pressed and repaired, which greatly improves the quality of road rolling. In order to accelerate the cooling of asphalt concrete, when the roller body 1 stops, the staff manually shakes the hand crank 205, and the hand crank 205 drives the rotating rod 209 to rotate, and the rotating rod 209 drives the hollow rod 208 to rotate, thereby driving the fixed block 2 to rotate as a whole, so that the fixed block 2 faces the asphalt ground at a suitable angle. At this time, the staff pushes the slider 207 to insert the slider 207 between the limit columns 204, thereby limiting the cylinder 203. At this time, the staff turns on the motor 304, and the rotation of the output end of the motor 304 drives the gear 2 302 to rotate, and the rotation of the gear 2 302 drives the gear 1 301 to rotate, so that the fan 3 starts to rotate, and then drives the roller body 1 to roll the road, so as to achieve the goal of accelerating the cooling of the asphalt concrete in time when the roller rolls the road, speeding up the construction progress, and putting the road surface into use in time.
