[0002] Pavement milling machine is one of the main types of machinery for asphalt pavement maintenance and construction, and one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for excavation and renovation of asphalt concrete surface layers in highways, urban roads, airports, freight yards, etc. It can also be used to remove road surface defects such as bulges, oil waves, reticulation, rutting, etc. It can also be used to excavate road potholes and grooves, as well as roughen cement pavement and mill out surface misalignment.

[0003] For example, a Chinese patent discloses: Asphalt pavement milling machine, patent number: CN215629233U. When adjusting the overall length of the push handle, the pull ring is pulled away from the milling machine body to pull the block out of the uppermost groove, and then the push handle is lifted until the extended square column is pulled out to a specified height, and the pull ring is released. Under the action of the spring, the block automatically enters the corresponding groove, thereby completing the length adjustment of the push handle.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the above device usually has a relatively fixed installation position of the milling drum, lacks a position adjustment function, and cannot be adjusted under different working requirements, which limits the adaptability of the milling machine.

When the asphalt layer needs to be removed, the distance between the milling drums can be increased to improve the milling efficiency. When fine milling and trimming are required, the distance between the milling drums can be reduced to improve the milling effect. Adjustments can be made when facing different needs to improve the adaptability of the device and improve the working efficiency.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the above-mentioned device is usually installed in a relatively fixed position of the milling drum, lacks a position adjustment function, cannot be adjusted under different working requirements, and limits the adaptability of the milling machine. The overall idea is as follows: it includes a milling machine body 11, both sides of the milling machine body 11 are fixedly connected with pulleys 12, the upper end of the milling machine body 11 is fixedly connected with a push handle 13, the upper end of the milling machine body 11 away from the push handle 13 is fixedly connected with a motor 14, the milling machine body 11 is internally rotatably connected with a rotating rod 15, the motor 14 and one side of the synchronous wheel 16 are sleeved with synchronous wheels 16, the outer surfaces of the two synchronous wheels 16 are sleeved with adjustment mechanisms, the adjustment mechanism includes a belt 17, the belt 17 is sleeved on the outer surfaces of the two synchronous wheels 16, and the milling machine body 11 is close to the push handle 13. A protective cover 18 is clamped on one side of the belt 17, and two synchronous wheels 16 are rotatably connected inside the protective cover 18. Two connecting gears 19 are sleeved on the outer surface of the synchronous wheel 16. Two milling drums 21 are rotatably connected inside the milling machine body 11. The outer surfaces of the two milling drums 21 are sleeved on one end close to the connecting gear 19. The two face gears 22 are respectively meshed with the connecting gear 19. The milling machine body 11 is pushed by the push handle 13, and the milling machine body 11 is driven by the pulley 12 to slide on the road surface. The motor 14 is started, and the output shaft of the motor 14 drives the synchronous wheel 16 to rotate. The synchronous wheel 16 drives the rotating rod 15 to rotate through the belt 17. The rotating rod 15 drives the face gear 22 to rotate through the meshing of the two connecting gears 19. The face gear 22 drives the milling drum 21 to rotate to mill and clear the road surface.

[0027] A connecting frame 23 is sleeved on the outer surface of the two face gears 22, and the connecting frame 23 is slidably connected to the inside of the milling machine body 11. A threaded rod 24 is threadedly connected to the inside of the milling machine body 11, and the threaded rod 24 is rotatably connected to the inside of the connecting frame 23. The threaded rod 24 is screwed, and the threaded rod 24 rotates forward to push the connecting frame 23 to slide in the milling machine body 11. A milling drum 21 is driven to slide through the connecting frame 23 to adjust the distance between the two milling drums 21. When it is necessary to remove the asphalt layer, the distance between the milling drums 21 can be increased to improve the milling efficiency. When fine milling and trimming are required, the distance between the milling drums 21 can be reduced to improve the milling effect. Adjustments can be made when facing different needs to improve the adaptability of the device and improve the working efficiency.

[0028] A water tank 25 is fixedly connected to the upper end of the milling machine body 11, and a nozzle 26 is sleeved inside the water tank 25.

When fine milling and trimming are required, the distance between the milling drums 21 can be reduced to improve the milling effect. Adjustments can be made when facing different needs, thereby improving the adaptability of the device and improving the working efficiency.

[0030] Working principle:

[0031] The first step is to push the milling machine body 11 through the push handle 13, and the milling machine body 11 is driven by the pulley 12 to slide on the road surface, and the motor 14 is started. The output shaft of the motor 14 drives the synchronous wheel 16 to rotate, and the synchronous wheel 16 drives the rotating rod 15 to rotate through the belt 17. The rotating rod 15 drives the face gear 22 to rotate through the meshing of two connecting gears 19, and the face gear 22 drives the milling drum 21 to rotate to mill and clear the road surface. The threaded rod 24 is screwed, and the threaded rod 24 rotates forward to push the connecting frame 23 to slide in the milling machine body 11, and a milling drum 21 is driven to slide through the connecting frame 23 to adjust the distance between the two milling drums 21. When the asphalt layer needs to be removed, the distance between the milling drums 21 can be increased to improve the milling efficiency. When fine milling and trimming are required, the distance between the milling drums 21 can be reduced to improve the milling effect. Adjustments are made when facing different needs to improve the adaptability of the device and improve the working efficiency.

[0032] The second step is to fill the water tank 25 with water before milling the road surface. When the milling drum 21 rotates to mill the road surface, the nozzle 26 sprays precipitation forward to absorb road dust through precipitation, thereby avoiding the generation of a large amount of dust during the milling process, reducing pollution to the environment and surrounding personnel, and helping to improve the air quality at the work site.
