[0022] Reference Figures 1 to 6 A cold-mix cold-paved asphalt mixture paving device comprises a tractor 10 and a paving system, wherein the paving system comprises a paving vehicle 2, a first discharge pipe 3, a second discharge pipe 4, a smoothing member 5, a blocking device, two asphalt boxes 6, a first pushing device 7 and a second pushing device 8, wherein the two asphalt boxes 6 are arranged on the paving vehicle 2 at intervals, the first discharge pipe 3 and the second discharge pipe 4 are respectively arranged on one asphalt box 6 and the first discharge pipe 3 and the second discharge pipe 4 are communicated, the smoothing member 5 is slidably arranged on the asphalt box 6, and a cover plate 601 is detachably provided on the asphalt box 6, the blocking device is arranged at the discharge port of the first discharge pipe 3, when the asphalt in the first discharge pipe 3 is squeezed, the blocking device operates to open the discharge port of the first discharge pipe 3, the first pushing device 7 is used to drive the asphalt in the asphalt box 6 to move upward, and the second pushing device 8 is used to drive the asphalt in the asphalt box 6 to move toward the first discharge pipe 3 or the second discharge pipe 4; and further comprises:

[0023] The connecting device is used to connect the tractor 10 and the paving vehicle 2. In the present invention, when paving asphalt on the road surface, the asphalt mixture is first poured into the two asphalt tanks 6 by the asphalt transport vehicle, the asphalt tanks 6 are filled with asphalt, and the cover plate 601 is covered and fixed on the asphalt tanks 6. The tractor 10 works to pull the paving vehicle 2 to move slowly, and the second pushing device 8 on the left works to push the asphalt in the asphalt tank 6 to make it fall into the first discharge pipe 3. There is a gap between the asphalt in the asphalt tank 6 and the cover plate 601. The first pushing device 7 on the left pushes the asphalt upward to contact the cover plate 601, and the first pushing device 7 on the right pushes the asphalt upward to contact the cover plate 601. The second pushing device 8 works to push the asphalt in the asphalt box 6 to make it fall into the second discharge pipe 4. There is a gap between the asphalt in the asphalt box 6 and the cover plate 601. The first pushing device 7 on the right pushes the asphalt upward to contact the cover plate 601. Then the second pushing device 8 on the left works again to push the asphalt in the asphalt box 6 to make it fall into the first discharge pipe 3. After the asphalt piled up in the first discharge pipe 3 is squeezed, the blocking device works to open the discharge port of the first discharge pipe 3, and the asphalt is discharged from the discharge port and falls on the road surface. There is a gap between the asphalt in the asphalt box 6 and the cover plate 601, the first pushing device 7 on the left pushes the asphalt to move upward and contact the cover plate 601, and the second pushing device 8 on the right works to push the asphalt in the asphalt box 6 to make it fall into the second discharge pipe 4. Since the first discharge pipe 3 and the second discharge pipe 4 are connected, the asphalt in the second discharge pipe 4 is squeezed and flows into the first discharge pipe 3, and finally discharged from the discharge port. There is a gap between the asphalt in the asphalt box 6 and the cover plate 601, the first pushing device 7 on the right pushes the asphalt to move upward and contact the cover plate 601, and then the second pushing device 8 on the left works to push the asphalt in the asphalt box 6 to fall into the first discharge pipe 3. Repeat the above operation, asphalt is always discharged from the first discharge pipe 3. When the smoothing member 5 is about to contact the asphalt on the road surface, the smoothing member 5 is lifted up to make it above the asphalt, and then the smoothing member 5 is lowered to make it contact with the asphalt on the road surface to pave it. Since the size of the tube cavity of the first discharge pipe 3 is fixed, and the asphalt in the first discharge pipe 3 is squeezed and discharged, the thickness of the asphalt paved on the road surface is more uniform. Specifically, the smoothing member 5 is in an I-shape, and one side of its bottom is in an arc shape; one end of the first discharge pipe 3 passes through the paving vehicle 2.

[0024] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0025] In this embodiment, the blocking device includes a driving device, a first baffle 9, a second baffle 11, a vertical plate 12, two cross bars 13, and a plurality of I-shaped rods 14 and a spring 15.
