The raw material mixture in the stirring chamber 21 enters the conveying chamber 31, the conveying motor 33 rotates the conveying screw 32, and the conveying screw 32 conveys the raw material mixture in the conveying chamber 31 to the first feeding plate 41 of the feeding channel 4, and the conveying screw 32 continues Turning, the raw material mixture at the left end pushes the raw material mixture at the right end to move to the right, so that the raw material mixture on the first feeding plate 41 enters the extrusion gap 51 between the first roller 511 and the second roller 512, and the raw material mixture passes through the first roller. After being squeezed between 511 and the second roller 512 , it is pushed to the second feeding plate 42 by the conveying screw 32 , and is discharged to the road surface from the discharge port 44 of the feeding channel at the end of the second feeding plate 42 .

Then the controller 81 controls the running mechanism to rotate the wheels, so that the vehicle body 1 moves forward (ie, leftward in Figures 1-3), and the paving roller 71 rolls on the road surface to make the raw material mixture adhere to the road surface to form a buffer layer ; While the laying roller 71 is rolling, the second heating element 812 in it heats the buffer layer to soften the glue, so that the buffer layer can be more firmly bonded to the road surface. When the car body 1 is moving, the controller 81 makes the feeding motor 63 work, and the feeding motor 63 vibrates the vibrating screen 64, so that the supplementary material is discharged from the discharge hole of the vibrating screen 64 and evenly scattered on the buffer layer, laying pressure When the roller 71 moves forward with the vehicle body 1, the supplementary material fills the gap between the granular material and the granular material in the buffer layer, and the excess supplementary material on the buffer layer continues to be pressed forward by the laying roller 71 to supplement other gaps.

After the raw material mixture is extruded by the extruding device 5 , the discharge speed (unit m/min) from the feeding channel 4 should be adapted to the advancing speed of the vehicle body 1 . The discharge speed of the supplementary material can be changed according to the width of the laying buffer layer, the diameter of the granular material, and the density of the granular material, for example, it can be 0.2kg/min.

When the ambient temperature is low, especially in winter, the granular material and glue in the stirring chamber 21 can be heated by the first heating element 811 to improve the fluidity of the glue and make the glue and the granular material mix more uniformly. The raw material mixture in the transfer chamber 31 can be heated by the second heating element 812 to improve the fluidity of the glue and facilitate the conveying of the raw material mixture.

During the movement of the vehicle body 1, a worker at the rear end of the continuous paving equipment can assist the vehicle body 1 to turn. When the path for laying the buffer layer is relatively simple, such as linear motion, the motion path of the vehicle body 1 can be set by the program so that it can move according to the specified path, so that no manual operation is required.

In order to lay a thin buffer layer on the road surface, for example, the thickness of the buffer layer is equal to the diameter of the granular material, the first roller 511 can be moved vertically through the adjustment mechanism, so that the height of the extrusion gap 51 is greater than the one of the granular material. The diameter is smaller than twice the diameter of the granular material; and when the diameters of different granular materials are different, the height of the extrusion gap 51 can also be changed through the adjustment mechanism.
