[0026] The effects achieved by the entire embodiment 1 are as follows: first, the water tank 201 is placed inside the fixed plate 204 to prevent the water tank 201 from shifting when the device is running; secondly, by opening the valve 207, water can enter the connecting pipe 208 through the outlet pipe 206, and finally flow out through the nozzle 209. An appropriate amount of water mist can be sprayed during the milling process, which effectively suppresses the generation of dust, protects the environment and the health of the operator, and reduces pollution to the environment.

[0027] Embodiment 2, as Figure 2-Figure 4 As shown, the milling mechanism 1 includes a bottom plate 101, a square hole 102 is opened on the top of the bottom plate 101, a square hole 103 is opened on the top of the bottom plate 101, a handle 104 is fixedly installed on the top of the bottom plate 101, four universal wheels 105 are fixedly installed on the bottom of the bottom plate 101, a support frame 106 is fixedly installed on the top of the bottom plate 101, two holes 107 are opened on the top of the support frame 106, and two hydraulic cylinders 108 are fixedly installed on the top of the support frame 106. A piston rod 109 is provided at the output end, a connecting frame 110 is fixedly installed between the bottoms of the two piston rods 109, the outer wall of the connecting frame 110 is provided with a second hole 111, the inner wall of the second hole 111 is movably inserted with a rotating rod 112, the outer wall of the rotating rod 112 is fixedly sleeved with a milling cylinder 113, a motor 114 is provided on one side of the outer wall of the rotating rod 112, the top of the bottom plate 101 contacts the bottom of the water tank 201, and the top of the bottom plate 101 is fixedly connected to the bottom of the fixed plate 204.

[0028] The effect achieved by the entire embodiment 2 is that when the device is used normally, the two hydraulic cylinders 108 are connected to the connecting frame 110 through the two piston rods 109. The height of the milling barrel 113 can be adjusted by the operation of the hydraulic cylinder 108. Secondly, the rotating rod 112 is fixedly connected to the milling barrel 113, and the rotating rod 112 is connected to the motor 114. The operation of the motor 114 can drive the milling barrel 113 to rotate to mill the ground, which helps to avoid road damage caused by excessive milling, and at the same time ensures the flatness and quality of the road surface after milling. Accurately controlling the milling depth also helps to improve the effect and efficiency of subsequent maintenance operations.

[0029] Among them, the hydraulic cylinder 108 and the motor 114 are both existing technologies, and their components and operating principles are all public technologies, so no further explanation will be given here.

[0030] Working principle: First, when the device is in normal use, the four universal wheels 105 at the bottom of the base plate 101 can be operated by holding the handle 104, which can keep the equipment stable during driving and reduce the shaking of the equipment caused by uneven or bumpy roads. This is not only conducive to protecting the equipment itself and reducing the risk of damage, but also ensures the quality and safety of the operation. Secondly, the water tank 201 is fixedly connected to the water outlet pipe 206, and the water outlet pipe 206 is fixedly connected to the connecting pipe 208, and the connecting pipe 208 is connected to a group of nozzles 209. The control valve 207 allows the water to flow out of the nozzle 209 through the water outlet pipe 206 to wet the ground, effectively suppress the generation of dust, keep the air in the working area clean, improve the working environment, and reduce the pollution of dust to the environment, which is in line with the green and environmentally friendly construction concept. Secondly, the top of the support frame 106 is fixedly installed There are two hydraulic cylinders 108, and piston rods 109 are provided at the output ends of the two hydraulic cylinders 108. The two piston rods 109 are fixedly connected to the connecting frame 110. The two hydraulic cylinders 108 run at the same time, driving the two piston rods 109 to extend and retract, thereby driving the connecting frame 110 to move up and down to adjust the height of the milling barrel 113. It can be adjusted as needed. The operator can more flexibly choose the milling depth and range, reduce unnecessary repeated operations and excessive milling, which not only saves working time but also improves working efficiency. At this time, the milling barrel 113 is lowered according to the ground conditions. Secondly, the motor 114 is connected to the rotating rod 112, and the rotating rod 112 is connected to the milling barrel 113. When the motor 114 is running, it can drive the rotating rod 112 to rotate, thereby causing the milling barrel 113 to rotate to operate on the ground.
