Detailed Implementation

[0022] The following combination Figures 1-5 The present invention will be described in further detail below.

[0023] This utility model discloses a device for cleaning milled surfaces of roads.

[0024] ReferenceFigure 5 A device for cleaning milled surfaces of road surfaces includes a road vehicle 1. The rear end of the road vehicle 1 is connected to a cleaning mechanism 3 via multiple support arms 2. Cleaning ropes 4 are arranged and clamped on the cleaning mechanism 3, and the milled surfaces of the road surface are cleaned by the cleaning ropes 4.

[0025] Reference Figure 1 , Figure 4 , Figure 5 The sweeping mechanism 3 includes an inner beam 5 and an outer beam 6. The inner beam 5 is snapped into the inside of the outer beam 6 and fastened by vertical bolts 7. The sweeping rope 4 is bent in the middle and snapped between the inner beam 5 and the outer beam 6. The two ends of the sweeping rope 4 are separated by long rods. The two ends of the sweeping rope 4 extend to the milled surface of the road surface. The sweeping rope 4 that has been used for a long time can be replaced by unscrewing the vertical bolts 7 and disassembling the inner beam 5 and the outer beam 6.

[0026] Reference Figure 1 , Figure 3 The cleaning mechanism 3 is provided in two sets arranged one in front of the other, which improves the cleaning effect. The two sets of cleaning mechanisms 3 are connected by a reinforcing beam 8.

[0027] Reference Figure 1 , Figure 2 , Figure 3 A clamping frame 9 is provided below the sweeping mechanism 3. The clamping frame 9 uses two I-beams 10 set back from each other and is fastened by transverse bolts 11. The clamping frame 9 clamps and constrains the sweeping rope 4.

[0028] Reference Figure 1 , Figure 2 , Figure 5 The road vehicle 1 and the sweeping mechanism 3 are provided with three support arms 2, including one upper support arm 12 and two lower support arms 13. The upper support arm 12 and the lower support arms 13 are rotatably connected to the rear end of the road vehicle 1 and rotatably connected to the sweeping mechanism 3. The lower support arm 13 is connected to the hydraulic rod 14 in the middle section and is lifted by the hydraulic cylinder 15. The hydraulic cylinder 15 is externally connected to the hydraulic cylinder on the road vehicle 1 and filled with hydraulic pressure. By adjusting the output of the hydraulic cylinder, the lower support arm 13 can be lifted up and down. At the same time, the hydraulic cylinder 15 itself has a certain amount of hydraulic pressure to ensure that the sweeping mechanism 3 is at a certain height with the road milling surface. The sweeping rope 4 extends to the road milling surface at both ends.

[0029] Reference Figure 1 , Figure 5 The cleaning mechanism 3 is connected to the support arm 2 with a reinforcing rib 16 to ensure the structural strength of the connection.

[0030] Reference Figure 2 The sweeping rope 4 is made of rigid metal strips, nylon ropes or plastic ropes. The sweeping rope 4 has a certain rigidity and strength. Multiple sweeping ropes 4 are arranged in rows to form a rigid brush-like structure.

[0031] The implementation principle of the device for cleaning milled road surfaces according to this utility model embodiment is as follows: When in use, first assemble the cleaning mechanism 3, arrange and snap the cleaning rope 4 onto the cleaning mechanism 3, fasten the inner beam 5 and the outer beam 6, and after the two ends of the cleaning rope 4 are gathered by the clamping frame 9, extend to the milled road surface. Then, connect the assembled cleaning mechanism 3 to the rear end of the road vehicle 1 through the support arm 2, and hydraulically adjust the height of the cleaning mechanism 3 from the ground, and the cleaning rope 4 cleans the milled road surface.
