[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0032] A highway maintenance and construction equipment, referring to Figure 1 and Figure 2 The system includes a frame 1, which is rotatably connected to wheels via a pivot shaft at its lower end. A motor mounted on the frame 1 and connected to a power source drives the wheels to rotate, thus moving the frame 1. One end of the frame 1 is hinged to a support frame 11, and the end of the support frame 11 away from the frame 1 is rotatably connected to a guide wheel 12 via a pivot shaft. This allows the guide wheel 12 to move along the markings drawn on the cracks in the road surface, reducing the possibility of the frame 1 veering off course. A fixing groove 13 is made on the frame 1 near the support frame 11, and a mounting frame 14 is placed in the fixing groove 13. A grooving cutter head 2 is rotatably connected to the mounting frame 14 via a bearing, so that the grooving cutter head 2 corresponds to the guide wheel 12. A drive component 21, which is an electrically connected drive motor, is bolted to one side of the mounting frame 14. The drive component 21 drives the grooving cutter head 2 to rotate, thus grooving the cracks in the road surface.

[0033] Reference Figure 1 and Figure 2 The grooving head 2 is located above the mounting bracket 14 and is fixed to the drive component 3 15 on both sides by bolts. The drive component 3 15 is a hydraulic cylinder connected to the power supply. The drive end of the drive component 3 15 passes through the mounting bracket 14 and is connected to the inner wall of the fixing groove 13. The drive component 3 15 drives the mounting bracket 14 to move downward, so that the grooving head 2 is close to the road surface to groove the crack. A groove 131 corresponding to the drive component 21 is provided on the inner wall of the fixing groove 13 to facilitate the movement of the drive component 21 with the mounting bracket 14.

[0034] Reference Figure 2 and Figure 3 Below the frame 1, a dust suction port 3 is bolted to correspond to the groove dug by the grooving head 2. Above the frame 1, it is bolted to the filter box 31, sealing the connection between the dust suction port 3 and the frame 1. A fan 32, connected to the filter box 31, is bolted to the side wall of the filter box 31. The fan 32, electrically connected to a power source, draws air, causing the dust suction port 3 to directly suck away dust and debris from the groove dug by the grooving head 2. A scraper 4, fitting against the groove wall, is positioned between the dust suction port 3 and the grooving head 2 on the frame 1. The width of the scraper 4 does not exceed the width of the grooving head 2. The dimensions are designed to prevent the scraper 4 from damaging the trench wall excavated by the grooving head 2, which would affect subsequent grouting and repair. A connecting rod 41, which runs through the frame 1, is bolted above the scraper 4. A second drive component 42, which is electrically connected to the power supply, is bolted above the connecting rod 41 on the frame 1. The drive end of the second drive component 42 is engaged and fixed with the connecting rod 41. The third drive component 15 drives the connecting rod 41 to move, so that the scraper 4 enters the trench excavated by the grooving head 2 to remove loose stones on the trench wall, which are then directly sucked away by the dust suction port 3 at the rear.

[0035] Reference Figure 2 and Figure 3 A rotating brush 5 is rotatably mounted on the frame 1 between the scraper 4 and the suction pipe 3. A telescopic rotating motor 51 is bolted to the top of the frame 1 between the filter box 31 and the drive component 42. The rotating brush 5 is bolted to the drive end of the telescopic rotating motor 51. The telescopic rotating motor 51 extends the rotating brush 5 into the groove excavated by the grooving head 2. Then, the telescopic rotating motor 51 drives the rotating brush 5 to rotate and clean the residual residue on the groove wall. The residue is then directly sucked away by the suction pipe 3 at the rear, reducing the impact of the remaining residue on subsequent grouting and repair.

[0036] Reference Figure 2 and Figure 3A protective cover 16 corresponding to the grooving head 2 is fixed above the mounting frame 14 with bolts and sealing gaskets. A dust suction hose 161 communicating with the filter box 31 is tightly connected to the protective cover 16 with bolts. The dust suction hose 161 communicates with the protective cover 16 to extract dust and some small particles generated by the grooving head 2 inside the protective cover 16, preventing dust from spreading. A protective plate 17 is fixed to the side of the mounting frame 14 near the ground with bolts. The protective plate 17 corresponds to the grooving head 2, which facilitates the rotation of the grooving head 2 to groove the cracks in the road surface. Several ball bearings 171 are embedded on the side of the protective plate 17 near the road surface. When the mounting frame 14 moves down to allow the grooving head 2 to groove the cracks in the road surface, the protective plate 17 is close to the road surface to reduce the possibility of dust spreading. When the frame 1 moves, the ball bearings 171 roll to reduce the wear on the protective plate 17, making the frame 1 move more smoothly.

[0037] The implementation principle of this application embodiment is as follows:

[0038] In actual operation, after the worker marks the cracks on the road surface, the guide wheel 12 on the frame 1 moves along the marking, and the drive component 15 on the frame 1 pushes the mounting frame 14 down, bringing the grooving cutter head 2 closer to the road surface. Then, the drive component 21 drives the grooving cutter head 2 to groove the crack. The dust generated by the grooving cutter head 2 is extracted by the dust suction hose 161 connected to the protective cover 16 to prevent the dust from scattering. The scraper 4 behind the grooving cutter head 2 loosens the groove wall. Loose stones are removed, and the telescopic rotating motor 51 extends the rotating brush 5 into the groove excavated by the grooving head 2. Then, the telescopic rotating motor 51 drives the rotating brush 5 to rotate and clean the remaining residue on the groove wall. The dust and debris cleaned by the scraper 4 and rotating brush 5 in the groove excavated by the grooving head 2 are sucked away by the dust suction pipe 3 behind the rotating brush 5, keeping the groove clean and reducing the impact of the residue left in the groove excavated by the grooving head 2 on subsequent grouting and repair.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
