Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of milling machines, in particular to a high-precision milling mechanism with an automatic leveling function. Background Art
[0002] As the road network ages, the roads will gradually age, and the road surface will gradually become uneven, cracked, material detached, and too smooth. Highway maintenance and renovation have gradually become a major component of urban construction. In this process, it is rare for the entire road to be destroyed and rebuilt. Instead, a layer of asphalt material on the road surface will be milled off and a new layer of asphalt oil surface will be laid. This will help to effectively save labor and material costs and quickly restore the normal traffic order of the city. Therefore, the milling machine plays an important role in this process. Its function is to mill off the entire road surface that needs to be renovated and repaired, and remove the cracked, loose, and smooth layer of the road surface.

The motor can drive the transmission shaft to rotate, thereby driving the milling drum at the bottom of the movable plate to rotate through the transmission belt, so that the ground is milled by the rotating milling drum; the inclined baffle can cooperate with the movable plate to shield the milling drum during work.

A group of connecting plates 3 are fixed to the outer wall at the bottom of the movable plate 2. The outer wall of one side of the connecting plate 3 is rotatably connected to the milling drum 4. The outer wall of the movable plate 2 is provided with a transmission mechanism, and the outer walls on the opposite sides of the movable plate 2 and the mounting plate 1 are provided with left and right pushing mechanisms; the top outer wall of the mounting plate 1 is provided with an operating room 15, and the outer wall on one side of the operating room 15 is fixed with a control panel 14, and the gyroscope 10 is electrically connected to the control panel 14.
[0032] When the milling mechanism moves forward as a whole, the leveling roller 8 at the bottom of the front rotating plate 11 will support the milling mechanism as a whole. When the road surface is uneven as a whole, the front rotating plate 11 will swing left and right under the support of the leveling roller 8 and the vertical rod 9. At the same time, the gyroscope 10 on the front rotating plate 11 will detect the angle of the front rotating plate 11 when it swings up and down in real time, and transmit the detected data to the control panel 14. After receiving the data, the control panel 14 will control the left and right pushing mechanism to push the movable plate 2 and the movable plate 2 relative to the inclination angle of the front rotating plate 11 according to the real-time inclination angle of the front rotating plate 11, so that the transmission shaft 6 at the bottom of the mounting plate 1 is relatively tilted by a corresponding angle according to the inclination of the road surface in front, so that the tilted transmission shaft 6 can fully grind the inclined and raised parts of the road surface, so that the milling mechanism can grind the road surface relatively flatly while continuously moving forward.
[0033] like Figure 2-5As shown, the left and right pushing mechanism includes an electric hydraulic push rod 18, a connecting frame 29, a movable frame 23 and a guide slide 22. The guide slide 22 is arranged on the top outer wall of the movable plate 2, and the movable frame 23 is slidably connected to the top outer wall of the guide slide 22.

The electric hydraulic push rod 18 is fixed to the bottom outer wall of the mounting plate 1, and the top outer wall of the connecting frame 29 is fixed to the output shaft of the electric hydraulic push rod 18. The electric hydraulic push rod 18 is electrically connected to the control panel 14; the control panel 14 controls the corresponding electric hydraulic push rod 18 to push the movable frame 23 downward or upward to move a corresponding distance on the guide slide 22 to change the overall inclination of the movable plate 2, so that the milling drum 4 at the bottom of the movable plate 2 can stably mill the road surface according to the inclination of the road surface. At the same time, the electric hydraulic push rod 18 can also cooperate with the guide plate 30 to fix and limit the movable plate 2 as a whole, thereby improving the overall stability of the movable plate 2.

The motor 21 can drive the transmission shaft 6 to rotate, thereby driving the milling drum 4 at the bottom of the movable plate 2 to rotate through the transmission belt 20, so that the ground is milled by the rotating milling drum 4.
[0035] like Figure 4-5 As shown, a rectangular groove 31 is provided on the bottom outer wall of the mounting plate 1, and an elastic telescopic rod 25 is fixed on the inner wall of the rectangular groove 31. A connecting column 26 is fixed on the bottom outer wall of the elastic telescopic rod 25, and the outer walls on both sides of the connecting column 26 are rotatably connected to movable blocks 27; the bottom outer wall of the movable block 27 is slidably connected to a fixed frame 28, and the fixed frame 28 is fixed to the top outer wall of the motor 21; the elastic telescopic rod 25 can buffer the motor 21 as the movable plate 2 rotates up and down through its own elastic force, and at the same time, the top outer wall of the motor 21 is supported and limited by the movable block 27 and the fixed frame 28, thereby improving the overall stability of the motor 21 during operation.
[0036] like Figure 1 As shown, inclined baffles 7 are fixed to the outer walls on both sides of the movable plate 2; a reserved through slot 5 is opened on the outer wall at the top of the movable plate 2; the inclined baffles 7 can cooperate with the movable plate 2 to shield the milling drum 4 when working.
[0037] When this embodiment is in use, when the milling mechanism moves forward as a whole, the leveling roller 8 at the bottom of the front rotating plate 11 will support the milling mechanism as a whole. When the road surface is uneven as a whole, the front rotating plate 11 will swing left and right under the support of the leveling roller 8 and the vertical rod 9. At the same time, the gyroscope 10 on the front rotating plate 11 will detect the angle of the front rotating plate 11 when it swings up and down in real time, and transmit the detected data to the control panel 14. After receiving the data, the control panel 14 will control the left and right pushing mechanism to push the movable plate 2 and the movable plate 2 relative to the inclination angle of the front rotating plate 11 according to the real-time inclination angle of the front rotating plate 11, so that the transmission shaft 6 at the bottom of the mounting plate 1 is relatively tilted by a corresponding angle according to the inclination of the road surface in front, so that the tilted transmission shaft 6 can fully smooth the inclined and raised parts of the road surface.
[0038] The control panel 14 changes the overall inclination of the movable plate 2 by controlling the corresponding electric hydraulic push rod 18 to push the movable frame 23 downward or upward to move a corresponding distance on the guide slide rail 22, so that the milling drum 4 at the bottom of the movable plate 2 can stably mill the road surface according to the inclination of the road surface. At the same time, the electric hydraulic push rod 18 can also cooperate with the guide plate 30 to fix the movable plate 2 as a whole. The motor 21 can drive the transmission shaft 6 to rotate, thereby driving the milling drum 4 at the bottom of the movable plate 2 to rotate through the transmission belt 20, so that the ground is milled by the rotating milling drum 4.

[0040] Example 2:
[0041] A high-precision milling mechanism with automatic leveling function, such as Figure 1-3 As shown, this embodiment makes the following improvements on the basis of embodiment 1: a group of L-shaped limit plates 13 are fixed to the outer wall of the top of the mounting plate 1, a buffer pad 12 is fixed to the outer wall of one side of the L-shaped limit plate 13, and the outer wall of one side of the front rotating plate 11 is slidably connected to the outer wall of one side of the L-shaped limit plate 13; the L-shaped limit plate 13 can limit and support the front rotating plate 11 when it rotates up and down, avoiding the risk of the milling mechanism tipping over due to the front rotating plate 11 flipping up and down too large, and at the same time, the buffer pad 12 can buffer the space between the front rotating plate 11 and the L-shaped limit plate 13 through its own elastic force, avoiding hard collision between the front rotating plate 11 and the L-shaped limit plate 13, thereby improving the stability of the milling mechanism during operation.
[0042] When this embodiment is in use, the L-shaped limit plate 13 can limit and support the front rotating plate 11 when it rotates up and down, avoiding the risk of the milling mechanism tipping over due to the front rotating plate 11 flipping up and down at too large an angle. At the same time, the buffer pad 12 can buffer the space between the front rotating plate 11 and the L-shaped limit plate 13 through its own elastic force.
