[0022] The lifting mechanism includes a fixed sleeve 201 fixedly connected to the bottom of the mounting plate 1, a hydraulic cylinder 202 fixedly connected to the inner wall of the fixed sleeve 201, and a connecting rod 203 fixedly connected to the output end of the hydraulic cylinder 202; The top of the screed plate 3 is fixedly connected to the bottom end of the connecting rod 203, and the screed plate 3 is moved by the hydraulic cylinder 202 to adjust the paving thickness.

[0023] The mounting plate 1 is mounted on the vehicle body by fixing bolts, and then the hydraulic cylinder 202 is started to drive the ironing plate 3 to move to a suitable height, and then asphalt is sprayed onto the road surface through the vehicle body, and the vehicle body is started. At this time, the electric heating plate 405 has heated the ethylene glycol to a suitable temperature, and the asphalt pile is pushed down, and the asphalt forms a loose asphalt layer on the ground through the asphalt pile. The ironing plate 3 is heated by ethylene glycol, so that the heating of the ironing plate 3 is more uniform, and the heated ironing plate 3 can prevent asphalt from sticking; During the process of paving asphalt, the vacuum pump 401 is in working state, so that the exhaust gas generated by the asphalt is adsorbed into the interior of the ironing plate 3 and brought into contact with ethylene glycol.

There are several air pumps 401 to improve the collection efficiency of the exhaust gas. When one pump fails, other pumps can continue to work to ensure the continuity and reliability of the system. The conveying mechanism includes an air inlet pipe 501 penetrating the screed plate 3 and fixedly connected to its side wall, and a carrying box 502 fixedly connected to the outer side wall of the screed plate 3 for temporarily storing gas; The tamping mechanism includes a driving member fixedly connected to the outer side wall of the ironing plate 3, a protective cover 6016 fixedly connected to the top of the driving member, and a pressing plate 6014 movably arranged at the bottom of the protective cover 6016.

[0025] The driving member includes a first cylinder 601 fixedly connected to the outer wall of the ironing plate 3, a heat-insulating displacer 602 movably arranged inside the first cylinder 601, a transmission rod 603 fixedly connected to the top of the heat-insulating displacer 602, and a first U-shaped rod 604 movably connected to the transmission rod 603, wherein the top plate of the first cylinder 601 adopts a cooler, the outer diameter of the heat-insulating displacer 602 is smaller than the inner diameter of the first cylinder 601, the top of the heat-insulating displacer 602 extends to the outer surface of the first cylinder 601, and the heat-insulating displacer 602 is connected to the first cylinder 601 through a dynamic seal, and the heat-insulating displacer 602 is set, so that a small amount of gas in the first cylinder 601 can exchange and flow up and down, while most of the gas is layered.

[0026] The driving member also includes a second U-shaped rod 605 fixedly connected to the end face of the first U-shaped rod 604, a connecting rod 606 movably arranged on the side wall of the second U-shaped rod 605, a second cylinder 607 fixedly connected to the top of the first cylinder 601, and a piston 608 movably arranged inside the second cylinder 607, wherein the interior of the second cylinder 607 is filled with hydrogen.

[0027] The second cylinder 607 is connected to the inside of the first cylinder 601. The bottom end of the connecting rod 606 is fixedly connected to the top end of the piston 608. The depth of the second U-shaped rod 605 is less than the depth of the first U-shaped rod 604. When the hot air passes through the bottom of the first cylinder 601, it will heat the first cylinder 601, thereby increasing the gas pressure inside the first cylinder 601, thereby pushing the piston 608 to the highest point. At this time, the momentum stored in the two U-shaped rods will push the piston 608 down to the middle position of the second cylinder 607. At the same time, the thermal insulation displacer 602 will be located at the bottom of the first cylinder 601, and the gas position At the top layer of the first cylinder 601, the temperature is lowered to reduce the pressure. At this time, the external air pressure will push the piston 608 to move downward. At this time, the momentum stored in the two U-shaped rods will drive the piston 608 to move upward, so that the piston 608 is located in the middle position of the second cylinder 607, and the thermal insulation displacer 602 is located at the top layer of the first cylinder 601, and the cycle is thus continued. The momentum stored in the U-shaped rod means that when the piston 608 and the thermal insulation displacer 602 are forced to move upward, they will drive the U-shaped rod to rotate upward. During this process, the U-shaped rod cannot rotate to the highest point. When the external force disappears, the U-shaped rod will rotate downward under the action of gravity.

[0028] The tamping mechanism further includes a transmission disc 609 fixedly connected to the end surface of the first U-shaped rod 604, and a protrusion 6010 fixedly connected to the outer side wall of the transmission disc 609; The protrusion 6010 includes a cylinder fixedly connected to the outer wall of the transmission disk 609 and a hemisphere fixedly connected to the end surface of the cylinder.

[0031] When the exhaust gas is purified, it will enter the inside of the disc-shaped pipe 504 through the intake pipe 501 and finally be discharged from the disc-shaped pipe 504. The disc-shaped pipe 504 can increase the circulation time of the gas in the carrying box 502, and the heat carried by the gas will heat the first cylinder 601, thereby increasing the gas pressure inside the first cylinder 601, thereby pushing the piston 608 to the highest point. At this time, the momentum stored in the two U-shaped rods will push the piston 608 down to the middle position of the second cylinder 607. At the same time, the heat insulation displacer 602 will be located at the bottom layer of the first cylinder 601, and the gas will be located at the top layer of the first cylinder 601, and the temperature will drop to reduce the pressure. At this time, the external air pressure will The piston 608 is pushed downward. At this time, the momentum stored in the two U-shaped rods will drive the piston 608 to move upward, so that the piston 608 is located in the middle position of the second cylinder 607, and the thermal insulation displacer 602 is located at the top layer of the first cylinder 601, and the cycle continues. During this process, the transmission disk 609 will start to do reciprocating pendulum motion, so that the protrusion 6010 reciprocates. When the protrusion 6010 moves the quadrant point, it will push the pressure plate 6014 to move downward and stretch the connecting spring 6015. When the protrusion 6010 moves to the highest point, the connecting spring 6015 will drive the pressure plate 6014 to move upward, so as to achieve the up and down movement of the pressure plate 6014, and then compact the laid asphalt.
