Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this utility model is to provide a soil shoulder leveling device to solve the problems existing in the prior art. It can level the soil on the soil shoulder and accurately calibrate the scraping height of the scraper assembly.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-2As shown, this embodiment provides a road shoulder leveling device 100, including a scraper plate assembly, which comprises several individual scraper plates, with the lower ends of each scraper plate at the same height. The scraper plate assembly is mounted on a connecting frame 10, which is mounted on the robotic arm of a traveling machine. The robotic arm of the traveling machine can move the connecting frame 10 to the working height and position. The lower edge of the scraper plate assembly (i.e., each individual scraper plate) is used to level the road shoulder surface 12. A first calibration bracket 3 is fixedly provided on one side of the scraper plate assembly, meaning that the relative height between the scraper plate assembly and the first calibration bracket 3 will not move. A first calibration rod 4 is connected to the first calibration bracket 3, and the first calibration rod 4 can move up and down on the first calibration bracket 3, meaning that the relative height between the first calibration rod 4 and the scraper plate assembly can change, and the lower end of the first calibration rod 4 can contact the road surface 11.

[0027] like Figure 1 As shown, if it is necessary to use a scraper assembly to level the soil on the roadside shoulder, the height of the lower edge of the scraper assembly needs to be determined first. At this point, the traveling machinery simply needs to drive the first calibration rod 4 into contact with the road surface 11, and then continuously adjust the relative position of the first calibration rod 4 and the first calibration bracket 3 to adjust the relative position of the scraper assembly. When the scraper assembly reaches the required height of the roadside shoulder surface 12, it is ready to begin work. The traveling machinery drives the connecting frame 10 to travel in a straight line along the road surface 11. During this time, the first calibration rod 4 remains in contact with the road surface 11, while the scraper assembly levels the soil on the roadside shoulder. The area where the scraper assembly passes is the leveled roadside shoulder surface 12.

[0028] In this embodiment, the scraper assembly includes two individual scraper plates, namely a first scraper plate 1 and a second scraper plate 2, and a first calibration bracket 3 is located on the side of the first scraper plate 1 away from the second scraper plate 2. The first scraper plate 1 is welded to the first calibration bracket 3 or fixedly connected by bolts or other means.

[0029] In this embodiment, as Figure 2 As shown, both the first scraper plate 1 and the second scraper plate 2 are L-shaped plates. Each scraper plate 1 and the second scraper plate 2 includes a front panel and a side panel. The front panel and the side panel are perpendicular to each other, and one side of the front panel is fixedly connected to one side of the side panel, forming a single integrated structure. The front panel of the first scraper plate 1 and the front panel of the second scraper plate 2 are parallel to each other, and the two side panels are located on opposite sides of the two front panels. The side panel of the first scraper plate 1, away from the second scraper plate 2, is fixedly connected to the first calibration bracket 3.

[0030] In actual use, the front panel is perpendicular to the travel path of the traveling machinery, so that the front panel can level the soil on the road shoulder. The two side panels on both sides prevent the soil in the middle from running to the sides, thus limiting its movement and facilitating later collection.

[0031] In this embodiment, the front panel of the first scraper plate 1 and the front panel of the second scraper plate 2 are staggered (that is, although they are parallel, they are not on the same plane). In other words, the front panels of the first scraper plate 1 and the second scraper plate 2 partially overlap and are arranged adjacent to each other. The purpose of this arrangement is to prevent the soil between the two side plates from falling out through the gap between the two front panels.

[0032] In this embodiment, a second calibration bracket 6 is connected to the side of the second scraper plate 2 away from the first scraper plate 1, which is symmetrically arranged with respect to the first scraper plate 1. The structure of the second calibration bracket 6 is basically the same as that of the first calibration bracket 3. A second calibration rod 7 is connected to the second calibration bracket 6, and the structure of the second calibration rod 7 is basically the same as that of the first calibration rod 4. The reason for setting up the second calibration bracket 6 is to be able to perform calibration work using the second calibration rod 7 in case of special road surface 11 or other situations.

[0033] In this embodiment, both the first calibration rod 4 and the second calibration rod 7 are calibration bolts. Both the first calibration bracket 3 and the second calibration bracket 6 are provided with threaded holes, and the calibration bolts are threadedly connected to these holes. When it is necessary to adjust the height of the calibration bolts, simply rotate the calibration bolts to adjust the relative height between the calibration bolts and the scraper plate assembly.

[0034] In this embodiment, a vertically arranged first transverse plate 5 is fixedly connected to one end of the first calibration bracket 3, and a vertically arranged second transverse plate 8 is provided on the second calibration bracket 6. A horizontally arranged transverse axis 9 is provided on the connecting frame 10. The first transverse plate 5 is connected to a first transverse component 13, and the second transverse plate 8 is connected to a second transverse component 14. Both the first transverse component 13 and the second transverse component 14 are mounted on the transverse axis 9, and both the first transverse component 13 and the second transverse component 14 can move laterally along the transverse axis 9, thereby driving the first transverse plate 5 and the second transverse plate 8 to move laterally in the horizontal direction. This further allows adjustment of the positional relationship between the first scraper plate 1 and the second scraper plate 2, thus making it suitable for earthen road shoulder surfaces 12 of different widths.

[0035] In this embodiment, both the first transverse member 13 and the second transverse member 14 are sleeve structures. Both the first transverse member 13 and the second transverse member 14 are sleeved on the transverse shaft 9. The transverse shaft 9 is an optical shaft structure, so that both the first transverse member 13 and the second transverse member 14 are slidably connected to the transverse shaft 9.

[0036] It should be noted that, to prevent the first transverse plate 5 and the second transverse plate 8 from rotating during transverse movement, a limiting plate can be provided on both the front and rear sides of the first transverse plate 5 and the second transverse plate 8. The two ends of the limiting plate are welded to the connecting frame 10. The limiting plate is used to limit the front and rear positions of the first transverse plate 5 and the second transverse plate 8, so that the first transverse plate 5 and the second transverse plate 8 can only remain in a vertical state. Alternatively, the inner walls of the first transverse member 13 and the second transverse member 14 can be provided with a slider structure, and a corresponding groove structure can be provided on the outer wall of the transverse shaft 9. The slider structure is inserted into the groove structure and slidably connected. This can also restrict the first transverse plate 5 and the second transverse plate 8 to only slide laterally.

[0037] In this embodiment, to drive the first lateral moving member 13 and the second lateral moving member 14 to move laterally, a first hydraulic cylinder and a second hydraulic cylinder are respectively provided on both sides of the connecting frame 10. The extension and retraction end of the first hydraulic cylinder is connected to the first lateral moving member 13 or the first lateral moving plate 5, and the extension and retraction end of the second hydraulic cylinder is connected to the second lateral moving member 14 or the second lateral moving plate 8. In this way, the relative position between the first scraper plate 1 and the second scraper plate 2 can be adjusted by controlling the extension and retraction of the first hydraulic cylinder and the second hydraulic cylinder.

[0038] In this embodiment, the traveling machine is an excavator, and the connecting frame 10 is installed at the end of the excavator's boom. Of course, those skilled in the art can also use other traveling devices with robotic arms, and are not limited to this one.
