A door body 9 is hinged at the opening. Inside the heating tank 7, there is a stirrer 8; the door body 9 of this structure is convenient to open for adding asphalt materials. Inside the heating tank 7, there is a heating jacket clip, mainly using a heating tube as a heating element; the stirrer 8 can stir the asphalt materials driven by a motor to prevent the asphalt materials from solidifying; on one side of the discharge port 2, there is an opening, and a discharge gate 3 is inserted into the opening. The discharge gate 3 is slidably connected with the discharge port 2; the discharge gate 3 of this structure can be slid open to facilitate the discharge of asphalt materials; on the top side of the mobile cart 1, a push handle 10 is fixedly connected. At the bottom of the mobile cart 1, there is a leveling component 4. There are multiple groups of the leveling component 4. The leveling component 4 further includes a connecting sleeve 44 fixed to the bottom of the mobile cart 1. An installation frame 42 is inserted into the bottom of the connecting sleeve 44. A pushing wheel 41 is rotatably connected to the inner side of the installation frame 42; a groove is provided on the outer wall of the installation frame 42, and a first bolt 43 is inserted into the outer wall of the connecting sleeve 44. One end of the first bolt 43 penetrates through the connecting sleeve 44 to be connected with the installation frame 42; the height of the installation frame 42 of this structure can be adjusted, so as to facilitate the adjustment of the height of the pushing wheel 41. By adjusting the height of the pushing wheel 41, the leveling work of asphalt materials with different thicknesses can be realized; on both sides of the mobile cart 1, a cleaning component 6 and an accelerating component 5 are respectively provided;

[0025] The leveling component 4 includes a pushing wheel 41 provided at the bottom of the mobile cart 1, and the pushing wheel 41 is located on one side of the discharge port 2;

[0026] The cleaning component 6 includes a fixed rod 61 provided on one side of the mobile cart 1. At the bottom of the fixed rod 61, there is a second shunt pipe 65. A nozzle 66 is obliquely connected to one side of the second shunt pipe 65. A second blower 67 is installed on one side of the fixed rod 61. The air outlet of the second blower 67 is connected to the second shunt pipe 65; by providing the second blower 67, an obliquely jetting airflow can be generated at the nozzle 66. The airflow jets on the ground, so that impurities such as fallen leaves on the ground can be cleaned, ensuring the cleanliness of the road and being beneficial to the quality of asphalt paving;

[0027] The acceleration component 5 includes a connecting frame 51. The connecting frame 51 has a right-angled "U" shape when viewed from above.

A first shunt pipe 52 is provided at the bottom of the connecting frame 51, and a first blower 53 is provided at the top of the connecting frame 51. The first shunt pipe 52 is connected to the air outlet of the first blower 53. By setting the first blower 53 in this device, air flow can be ejected at the first shunt pipe 52. Therefore, after the paving work is completed in the front, the air flow can be used to accelerate the cooling of the asphalt material, facilitating the subsequent rolling work after rapid cooling. The moving direction of the mobile trolley 1 is from right to left.

[0028] Working principle: When using this asphalt mixture paving device, first, the staff enters the inside of the connecting frame 51, and then holds the push handle 10 to push the mobile trolley 1 to move. During the movement of the mobile trolley 1, the second blower 67 is first turned on, and the nozzle 66 ejects air flow obliquely to the ground, causing the impurities on the ground to move forward. Then, the discharge gate 3 is opened, and the asphalt material is discharged from the discharge port 2 to the ground. Since the mobile trolley 1 is in a moving state, the push wheel 41 comes into contact with the asphalt material. As the push wheel 41 rotates, the asphalt material can be leveled. The leveled asphalt material passes through the first shunt pipe 52 as the mobile trolley 1 moves. At this time, the air flow ejected by the first shunt pipe 52 can quickly cool the asphalt material, which is beneficial to shortening the cooling time and facilitating the subsequent pressing work.
