[0018] See also Figure 1-2 The rotary trimming device of the double-steel-wheel vibratory roller is installed on the roller and includes a bracket plate 1. A cylinder 2 is installed at one end of the bracket plate 1, and a slide groove is opened at the other end, and a movable plate 12 is slidably connected to the slide groove. The telescopic part of the cylinder 2 is connected to the movable plate 12, and a mounting shaft 15 is fixedly connected to the movable plate 12. The mounting shaft 15 is rotatably connected to the trimming piece 4, and the trimming piece 4 includes a connecting rod 41. A motor 42 is installed on the connecting rod 41, and a cutting disc 43 is fixedly connected to the power shaft of the motor 42. Two limit members 13 are provided on the movable plate 12, and the two limit members 13 are located on both sides of the mounting shaft 15. The operator can then manually hold the connecting rod 41 in the trimming piece 4 and flip the connecting rod 41 around the mounting shaft 15 so that the cutting disc 43 is flipped out and fixed by the limit piece 13 located on the side of the mounting shaft 15 away from the oil cylinder 2. Then, the motor 42 is controlled to drive the cutting disc 43 to rotate, and the road surface cutting can be performed according to the operation of the road roller. The operator can control the movement of the movable plate 12 by controlling the extension and contraction of the oil cylinder 2, thereby adjusting the height of the cutting disc 43 and the ground, so as to ensure that the cutting disc 43 can accurately perform the road surface cutting work. When the use is completed, the operator can hold the connecting rod 41 in the trimming piece 4 and flip it back to its original position, so that the connecting rod 41 is fixed to the limit piece 13 located on the side of the mounting shaft 15 close to the oil cylinder 2, thereby realizing the storage of the cutting disc 43, avoiding the situation that the cutting disc 43 cannot be stored after the oil cylinder 2 lifts the entire trimming piece 4 when not in use, thereby ensuring the safe storage of the cutting disc 43.

[0019] In some embodiments, support plates 11 are welded on both sides of the bracket plate 1, and mounting plates 3 are mounted on the support plates 11 by bolts. The mounting plates 3 are connected to the roller. The operator can install the device at any position on the roller through the mounting plates 3, which is very convenient for assembly and disassembly.

[0020] In some embodiments, the middle sides of the connecting rod 41 are shaped like a figure eight, and the middle portions of the two limiting members 13 are provided with similar figure eight-shaped grooves 14. The figure eight-shaped connecting rod 41 can improve the load-bearing strength of the connecting rod 41 on the trimming member 4, ensuring stable operation of the device. At the same time, the grooves 14 of the limiting members 13 fit the figure eight-shaped connecting rod 41 and can completely fit the connecting rod 41, ensuring the limiting of the connecting rod 41 and preventing the connecting rod 41 from loosening and causing the cutting disc 43 to fall and cause accidents.

[0021] In some embodiments, rubber pads are provided in the grooves 14 of the two stoppers 13. The rubber pads not only help the stoppers 13 better secure the connecting rod 41, but also cushion the connecting rod 41 when the operator places the connecting rod 41 on the stoppers 13 and when the cutting disc 43 is operating, thereby offsetting the impact on the connecting rod 41 and extending the service life of the device.

[0022] In some embodiments, the diameter of the cutting disc 43 is smaller than the distance between the two mounting plates 3. This ensures that when the operator folds up the cutting disc 43, the cutting disc 43 can be located between the two mounting plates 3 without being blocked, achieving perfect folding and preventing the cutting disc 43 from leaking out and posing a safety hazard.

[0023] In some embodiments, the connecting rod 41 is provided with ridges on both sides, and the retaining member 13 is provided with a retaining strip inside, and both the ridges and retaining strip are made of rubber. When the operator flips the connecting rod 41 and secures it with the retaining member 13, the ridges on the connecting rod 41 come into contact with the retaining strip and are squeezed and positioned below the retaining strip, allowing the retaining member 13 to restrain the connecting rod 41 and thus achieve a secure connection.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
