Technical Field

[0001] This utility model relates to the field of road roller technology, specifically to a walk-behind road roller with adjustable compaction depth. Background Technology

[0002] Walk-behind rollers are mainly used for compaction of various engineering foundations, including asphalt surface compaction, ditch foundations, roads, sports fields and lawn leveling and compaction, and can even be used for lawn rolling; their small size and compact structure allow them to operate flexibly in narrow areas, making them particularly suitable for use in places where large rollers cannot enter.

[0003] Chinese patent discloses a walk-behind roller (authorization announcement number CN208792104U). This patented technology solves the problem of the difficulty in cleaning the material adhering to the roller of the existing walk-behind roller. It can conveniently and quickly clean the adhering material on the roller of the walk-behind roller. However, it cannot smooth the road surface in front of it and cannot control the compaction depth. Utility Model Content

[0019] Please see Figures 1-4 In this embodiment of the utility model, the adjustable compaction depth hand-held roller includes a roller body 1 and a vibratory roller 5 located at the lower end of the roller body 1. A support frame 2 is installed on both sides of the lower end of the roller body 1 near the vibratory roller 5. A support roller 3 is installed at the lower end of each support frame 2. A leveling and shoveling mechanism 4 is installed on one side of one of the support frames 2. A handle 6 is installed on one side of the roller body 1. Supported on the ground by a set of support rollers 3, the hand-held roller can be made to move stably.

[0020] exist Figure 1 and Figure 2 In the process, the shoveling and leveling mechanism 4 includes a shovel plate 41 and a scraper plate 44. A set of hydraulic cylinders 47 and a rotating rod 42 are installed on the front and rear sides of the lower end of the shovel plate 41. A set of hydraulic cylinders 43 and a rotating rod 45 are installed on the front and rear sides of one end of the scraper plate 44. The hydraulic cylinders 47, 42, 43, and 45 are all mounted on a connecting arm 46, which is fixedly mounted on the support frame 2. By extending and retracting the hydraulic cylinders 47, the shovel plate 41 can be moved at the rotating rod 42. The shovel plate 41 rotates at a certain angle, bringing it closer to the vibratory roller 5. As the vibratory roller 5 rotates, the shovel plate 41 can scrape away the soil adhering to it, ensuring the quality of the road rolling. The extension and retraction of the hydraulic cylinder 43 can drive the scraper plate 44 to rotate at a certain angle at the rotating rod 45. By adjusting the angle of the scraper plate 44, the soil layer in front of the vibratory roller 5 can be leveled by the scraper plate 44 during its rotation, ensuring the quality of the road rolling.

[0021] exist Figure 1 and Figure 3 In this vibratory roller 5, a roller shell 51 is included. A vibration mechanism 54 is installed inside the roller shell 51, and a hub motor 55 is installed on the front side of the roller shell 51. A roller frame 52 is installed on the outside of the roller shell 51, and a set of shock absorbers 53 is installed on the upper end of the roller frame 52. The output end of the hub motor 55 is fixedly connected to the roller shell 51. The lower side of the front end of the roller frame 52 is fixedly connected to the outer shell of the hub motor 55, and the lower side of the rear end of the roller frame 52 is rotatably connected to the roller shell 51. The hub motor 55 drives the roller shell 51 to rotate inside the roller frame 52. The vibration mechanism 54 causes the roller shell 51 to vibrate up and down. The shock absorbers 53 buffer the roller shell 51. When the user holds the handle 6, the hand-held roller can move and perform vibratory roller operation.

[0022] exist Figure 3 and Figure 4 In this structure, the vibration mechanism 54 includes a rotary motor 541. A reducer 543 is installed at both the front and rear ends of the rotary motor 541. A rotating shaft 544 is fixedly connected to the output end of the reducer 543. An eccentric block 545 is installed on the rotating shaft 544. The rotary motor 541 drives the reducer 543 to rotate. After the reducer 543 changes speed, it drives the rotating shaft 544 and the eccentric block 545 to rotate together at a certain speed, thereby causing the vibration mechanism 54 and the roller shell 51 to vibrate together. When the reducer 543 causes the rotating shaft 544 to rotate at different speeds, the vibration mechanism 54 can vibrate at different frequencies and amplitudes, thus adjusting the compaction depth of the roller shell 51. A fixing frame 542 is fixedly connected to the outside of each reducer 543. The fixing frame 542 is fixed to the inner wall of the roller shell 51, thus making the vibration mechanism 54 and the roller shell 51 form a whole. When the vibration mechanism 54 vibrates, it drives the roller shell 51 to vibrate.

[0023] The working principle of this utility model is as follows: When compaction is required in a narrow area, first, hold the handle 6 and turn on the hub motor 55. The hub motor 55 drives the roller shell 51 to rotate inside the roller frame 52, which allows the hand-held roller to move. When the handle 6 controls the direction of travel of the hand-held roller, the hand-held roller is moved to the position that needs to be compacted.

[0024] Next, start hydraulic cylinder 2 43, which drives the scraper plate 44 to rotate at a certain angle at the rotating rod 2 45. Adjust the angle of the scraper plate 44, and the vibratory roller 5 can scrape the soil layer in front of the vibratory roller 5 through the scraper plate 44 during the rotation process.

[0025] Next, the rotary motor 541 is started, which drives the reducer 543 to rotate. After the speed is changed by the reducer 543, the rotary shaft 544 and the eccentric block 545 rotate together, thereby causing the vibration mechanism 54 and the road roller shell 51 to vibrate together, so as to compact the road.

[0026] When mud adheres to the roller shell 51, the hydraulic cylinder 47 is activated. The hydraulic cylinder 47 drives the shovel plate 41 to rotate at a certain angle at the rotating rod 42, so that the shovel plate 41 is close to the vibratory roller 5. During the rotation of the vibratory roller 5, the shovel plate 41 can scrape off the mud adhering to the vibratory roller 5 to ensure the quality of the road rolling.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
