[0057] This invention creates a cavity in the machine body 1, arranges the cleaning components within the cavity, and uses a first driving component to move the first brush roller 2 up and down relative to the machine body 1. The first brush roller 2 extends out of the machine body 1 only when the machine body 1 moves to the filling area. Through the elastic connection between the first brush roller 2 and the machine body 1, and its up-and-down movement relative to the machine body 1, the contact cleaning effect between the first brush roller 2 and the filling area is effectively guaranteed, thereby improving the filling effect.

[0078] The third motor 19 rotates the gear 18, which meshes with the rack 17. The rack 17 drives the fixed plate 16 and the support plate 20 to rise and fall relative to the machine body 1, thereby realizing the lifting and lowering control of the first brush roller 2.

[0079] Furthermore, the first drive component also includes:

[0080] The outer casing 21 is fixedly attached to the support plate 20;

[0081] The first support 22 is rotatably connected to the support shell 21. A torsion spring 23 is wound around the first support 22, and the two ends of the torsion spring 23 are fixedly connected to the first support 22 and the support shell 21 respectively.

[0083] By fixing the support shell 21 to the support plate 20, the first support 22 is rotatably connected to the support shell 21 using a torsion spring 23. A first support rod 24 is fixed to the first support 22, and the other end of the first support rod 24 extends out of the support shell 21 and is fixed to a second support rod 25. The first support rod 24 is then rotatably connected to the support shell 21, and the second support rod 25 extends downwards at an angle. After the first brush roller 2 contacts the road surface, the second support rod 25 can drive the first support rod 24 to rotate the first support 22, thereby providing elastic support for the first brush roller 2 through the torsion spring 23. A fourth motor 27 fixed to the second support 26 drives the first brush roller 2 to rotate, cleaning the filling area.

[0085] Water tank 28 is fixedly connected in the cavity. Several connecting pipes 29 extend from the bottom of water tank 28. Spray nozzles 30 are connected to the bottom of the connecting pipes 29 and face the opening.

[0086] Water is sprayed from the opening of the water tank 28, which, in combination with the first brush roller 2, enhances the cleaning effect on the filling area and wets the road surface, reducing dust generated during the subsequent cutting process of the cutter 3 and reducing the environmental impact during the filling process.

[0087] Furthermore, the filling component includes:

[0088] Material box 31 is fixedly connected to machine body 1. The bottom end of material box 31 is connected to conveying pipe 32.

[0091] A road construction method for road repair and leveling, based on the aforementioned road construction equipment for road repair and leveling, includes the following steps:

[0092] Move unit 1 to the filling area;

[0093] The third motor 19 is started to rotate the gear 18, which drives the rack 17 to rise and fall, so that the first brush roller 2 slides into contact with the road surface until it compresses the torsion spring 23;

[0094] Water is sprayed through nozzle 30 and the fourth motor 27 is started to rotate the first brush roller 2;

[0095] The cylinder 10 is activated to lower the lifting plate 7, so that the cutter 3 contacts the filling area. The first motor 12 is activated to rotate the cutter 3 to clean the road surface. During the process, the second motor 15 is activated to drive the second brush roller 8 to rotate.

[0096] After the road surface is cleaned, the filling head 33 is moved to the filling area for filling, and then the filling area is flattened by the pressure roller 4 at the rear end of the machine body 1.

[0097] The filler material is fed into the material box 31, and then the fifth motor 35 rotates the stirring rod 34. While the first motor 12 drives the first brush roller 2 to rotate and clean the road surface, the third motor 19 rotates the gear 18, causing the second support rod 25 to squeeze the first support rod 24 and the first support 22. The elastic action of the torsion spring 23 ensures the contact between the first brush roller 2 and the road surface. The cylinder 10 drives the lifting plate 7 to descend, so that the cutter 3 cuts and cleans the crack area, enhancing the applicability of the filler. During the cutting process, the second brush roller 8 cleans the impurities cut by the cutter 3, further improving the cleaning effect and ensuring the filling effect. After filling through the filling head 33, the sixth motor 5 drives the pressure roller 4 to move and compact the filled area, completing the road surface repair and compaction.
