[0033] The bottom of the workbench 1 is provided with a plurality of movable brackets 26, and the bottoms of the plurality of movable brackets 26 are all provided with movable wheels 27 for rotation;

[0034] A torsion block 28 is provided on the top of the threaded column 2;

[0035] A feed hopper 29 is provided on the top of the mixing drum 11 .

[0036] Through the above operations, the materials on the roadbed can be evenly dispersed, and materials of different thicknesses can be dispersed according to specific circumstances.

[0037] Specifically, first, the height of the connecting plate 5 is adjusted according to the thickness of the material to be laid, and the twist block 28 is rotated to rotate the threaded column 2. The rotation of the threaded column 2 drives the connecting plate 5 threadedly connected to the surface of the threaded column 2 to move up and down with the assistance of the guide column 3, thereby realizing the adjustment of the height of the connecting plate 5, and finally easily realizing the adjustment of the distance between the cross paving plate 8 and the roadbed, which is convenient for paving materials of different thicknesses.

[0038] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 4, the stirring mechanism includes a stirring drum 11 provided on the top of the workbench 1, a stirring rod 12 is rotatably connected to the inside of the stirring drum 11, a second motor 13 for driving the stirring rod 12 to rotate is provided on the top of the stirring drum 11, a spiral blade 14 is provided on the surface of the stirring rod 12, and a cross-shaped stirring rod 15 is provided at the bottom of the stirring rod 12;

[0040] The surface of the workbench 1 is provided with a communication port 17 corresponding to the passage formed by the plurality of converging inclined platforms 16 , and an electric telescopic door is provided inside the communication port 17 , one end of which can be driven by a device such as a cylinder.

[0041] Through the above operations, the material inside the mixing drum 11 can be prevented from solidifying.

[0042] Specifically, materials are added to the mixing drum 11 from the feed hopper 29, and the second motor 13 is started to rotate the stirring rod 12. The rotation of the stirring rod 12 drives the spiral blade 14 and the cross-shaped stirring rod 15 to rotate, effectively preventing the solidification of the materials.

[0043] In a specific embodiment, as shown in the attached Figure 2 、 5 As shown in FIG6 , the dispersion mechanism includes a rubber layer 18 arranged outside the communication port 17 , a dispersion cylinder 19 is provided at the bottom of the rubber layer 18 , a plurality of dispersion plates 20 are evenly arranged inside the dispersion cylinder 19 , and vibration motors 21 are provided on both sides of the dispersion cylinder 19 .

[0044] Through the above operations, the materials can be preliminarily dispersed.

[0045] Specifically, by controlling the electric telescopic door, the material in the mixing drum 11 falls into the dispersion drum 19 through the connecting port 17 with the assistance of the gathering ramp 16. Under the action of the dispersion plate 20, the material is dispersed and falls into the dispersion drum 19. With the assistance of the vibration motor 21, it is discharged from the bottom of the dispersion drum 19. Through the above operations, the preliminary dispersion of the material is achieved.

[0046] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, a heating component is provided on one side of the stirring mechanism, and the heating component includes a steam generator 22 arranged on the top of the workbench 1 and two steam pipes 23 arranged at the bottom of the workbench 1, and the steam generator 22 and the two steam pipes 23 are connected, and multiple steam nozzles are provided at the bottom of the two steam pipes 23.

[0047] Through the above operations, the adhesion effect between the pavement layers can be guaranteed.

[0048] Specifically, the locomotive 24 and the steam generator 22 are started, the locomotive 24 pulls the workbench 1 to move, and the steam generated by the steam generator 22 passes through two steam pipes 23 and is discharged from the steam head. Through the above operation, the underlying pavement can be preheated to ensure the bonding quality between the pavement layers, and the thermal connection of the horizontal and vertical construction working seams can be achieved, greatly improving the paving quality of the pavement.

[0049] Working principle of the utility model: First, the height of the connecting plate 5 is adjusted according to the thickness of the material to be paved, and the twist block 28 is rotated to rotate the threaded column 2. The rotation of the threaded column 2 drives the connecting plate 5 threadedly connected to the surface of the threaded column 2 to move up and down with the assistance of the guide column 3, thereby achieving the adjustment of the height of the connecting plate 5, and finally easily achieving the adjustment of the distance between the cross paving plate 8 and the roadbed, which is convenient for paving materials of different thicknesses;

[0050] After adjusting the height of the connecting plate 5, add the material from the feed hopper 29 to the mixing drum 11, start the second motor 13, and rotate the stirring rod 12. The rotation of the stirring rod 12 drives the spiral blade 14 and the cross-shaped stirring rod 15 to rotate, effectively preventing the solidification of the material.

[0051] Then, the locomotive 24 and the steam generator 22 are started. The locomotive 24 pulls the workbench 1 to move. The steam generated by the steam generator 22 passes through two steam pipes 23 and is discharged from the steam head. The above operation can preheat the bottom pavement to ensure the bonding quality between the pavement layers and realize the thermal connection of the horizontal and vertical construction working joints, greatly improving the paving quality of the pavement.

[0052] By controlling the electric telescopic door, the material in the mixing drum 11 falls into the dispersion drum 19 through the communication port 17 with the assistance of the gathering ramp 16. Under the action of the dispersion plate 20, the material falls into the dispersion drum 19 and is discharged from the bottom of the dispersion drum 19 with the assistance of the vibration motor 21. Through the above operation, the preliminary dispersion of the material is achieved, which prevents the material from falling directly due to adhesion and forming a large accumulation, which is conducive to the subsequent paving operation.

[0053] After the material is discharged from the dispersion cylinder 19, the guide plate 10 gathers the material at the edge, and the first motor 7 is started to rotate the rotating rod 6. The rotation of the rotating rod 6 drives the cross paving plate 8 to rotate. Under the restriction of the baffle 9, the material on the roadbed is evenly dispersed, effectively preventing the subsequent uneven road surface caused by material accumulation.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
