[0002] With the improvement of living standards and the development of rural and urban areas, more and more dirt roads will be built. During the construction process, in order to ensure the long service life of the paved road surface, the dirt road will be leveled to make it flat, which will facilitate the laying of concrete or asphalt and reduce the difficulty of construction, thus making the construction process easier.

[0003] When leveling a dirt road, a roller is used to compact the soil to ensure it is firm and prevent it from sinking. However, during the compaction process, the presence of soil piles on the original road surface causes the roller to tilt as it travels over these piles, affecting the overall balance. To address this issue, a leveling device for saline soil roadbed construction is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when leveling a dirt road, a roller is used to compact the soil to ensure its compaction and prevent it from sinking. However, during the compaction process, the presence of soil piles on the original dirt road surface causes the roller to tilt when it travels over the soil piles, which affects the overall balance. Therefore, a leveling device for saline soil roadbed construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leveling device for construction of saline soil subgrade, comprising a first mounting frame, a support plate fixedly connected to the top of the first mounting frame, a scraping component provided at the bottom of the support plate, and a rolling component fixedly connected to one end of the first mounting frame;

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by providing a push plate inside, during construction, the installation plate can be moved by rotating the threaded rod, which in turn moves the push plate downwards. This allows the push plate to level any excessively high soil piles during movement. Furthermore, when the road is compacted by the pressure roller, the scraper can remove the soil adhering to the surface of the pressure roller. This design enables the push plate to level the rotary tilled soil during road leveling, thus preventing the pressure roller from tilting due to excessively high soil piles and affecting its balance. Additionally, the scraper can wipe the surface of the pressure roller during compaction, preventing more soil from adhering to its surface.

[0023] 2. In this utility model, a cam is provided inside. During the rolling process of the pressure roller, the cam can drive the cam to rotate, thereby allowing the support frame to move on the cam surface. The support frame can move with the rotation of the cam and drive the striking rod to strike the pressure roller. Through this design, when the pressure roller is used to compact the soil road, the cam can drive the support frame and striking rod to move and strike the pressure roller, thereby shaking off the soil on the surface of the pressure roller through vibration, and further cleaning the soil on the surface of the pressure roller.

A mounting plate 35 is fixedly connected to the bottom end of the mounting rod 34, and a push plate 36 is fixedly connected to the bottom end of the mounting plate 35. A threaded rod 33 is rotatably connected to the mounting rod 34 through a through hole therein. A fixing block 32 is fixedly connected to one side of the second mounting bracket 31, and a sliding rod 38 is slidably connected to the fixing block 32 through a groove therein. A scraper 39 is fixedly connected to one end of the sliding rod 38, and a first spring 37 is fixedly connected to the other end of the sliding rod 38.

[0033] The other end of the first spring 37 is fixedly connected to the fixing block 32, the two ends of the second mounting bracket 31 are fixedly connected to the first mounting bracket 1, the threaded rod 33 is threadedly connected to the support plate 2 through the threaded hole opened in the support plate 2, and there are two push plates 36 with a certain included angle between them.

[0034] The specific implementation method is as follows: During construction, the installation plate 35 can be moved by rotating the threaded rod 33 and the push plate 36 can be moved downward, thereby adjusting the distance between the push plate 36 and the ground to a suitable position. When the drive equipment moves the first installation frame 1, the push plate 36 can be moved and the excessively high soil pile can be leveled by the push plate 36. When the soil road is flattened by the pressure roller 48, the first spring 37 can push the slide rod 38 to make the scraper 39 fit with the pressure roller 48, thereby scraping off the soil adhering to the surface of the pressure roller 48 by the scraper 39.

[0035] The rolling assembly 4 includes a third mounting bracket 41, one side of which is fixedly connected to the first mounting bracket 1. A pressure roller 48 is rotatably connected to the third mounting bracket 41 through a through hole. Cams 47 are fixedly connected to both ends of the pressure roller 48. A limit rod 42 is slidably connected to the third mounting bracket 41 through a through hole. A support frame 46 is fixedly connected to the bottom end of the limit rod 42. A support block 44 is fixedly connected to the bottom surface of the support frame 46. A striking rod 45 is rotatably connected to the support block 44 through a through hole. A second spring 43 is provided on the outer wall of the limit rod 42. The bottom end of the second spring 43 is fixedly connected to the support frame 46, and the top end of the second spring 43 is fixedly connected to the third mounting bracket 41. The top end of the second spring 43 is located in a groove on the bottom surface of the third mounting bracket 41. The bottom end of the support frame 46 is in contact with the cam 47.

[0036] The specific implementation is as follows: During the rolling process of the pressure roller 48, it can drive the cam 47 to rotate, thereby allowing the support frame 46 to move on the surface of the cam 47. As the cam 47 rotates, the support frame 46 can rise, and when the support frame 46 slides past the top of the cam 47, the second spring 43 can cause the support frame 46 to fall immediately, thereby driving the striking rod 45 to move downward and strike the pressure roller 48.

[0037] Working principle: During construction, the rotating threaded rod 33 drives the mounting plate 35 to move and the push plate 36 to move downward, thereby adjusting the distance between the push plate 36 and the ground to a suitable position. When the drive equipment moves the first mounting frame 1, the push plate 36 can move and level any excessively high soil piles. When the road is flattened by the pressure roller 48, the first spring 37 pushes the sliding rod 38 to make the scraper 39 fit against the pressure roller 48, thereby scraping off the soil adhering to the surface of the pressure roller 48. During the rolling process of the pressure roller 48, it drives the cam 47 to rotate, causing the support frame 46 to move on the surface of the cam 47. The support frame 46 can rise with the rotation of the cam 47. When the support frame 46 slides past the top of the cam 47, the second spring 43 causes the support frame 46 to fall immediately, thereby driving the striking rod 45 to move downward and strike the pressure roller 48.
