As the supporting structure of highways, the stability and durability of the roadbed are crucial to the operation of the entire highway system. During the construction of highways, rollers are needed to compact the roadbed. However, most existing rollers are only equipped with a single roller during use, and the roller is pushed along the roadbed by an engineering vehicle to compact the roadbed. However, the surface of the above-mentioned roller is prone to sticking to mud during use, and the mud remaining on the surface of the roller may affect the subsequent compaction effect of the roller on the roadbed. To this end, we propose a compaction device for highway roadbeds. Utility Model Content

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a technical solution: a compacting device for a highway roadbed, comprising a fixed frame 1, a connecting plate 2 being welded and fixed to one side wall of the fixed frame 1, the connecting plate 2 being used to be connected and fixed to the frame of engineering equipment, the fixed frame 1 can be pushed to move by external engineering equipment, an assembly groove 3 is opened in the fixed frame 1, a roller 4 is rotatably connected in the assembly groove 3, the fixed frame 1 is pushed to move by an external engineering equipment vehicle, the roller 4 can rotate in the assembly groove 3, and the compacting operation of the roadbed in the highway is completed.

[0016] A cleaning mechanism 5 is fixedly assembled at one end of the top of the fixing frame 1 away from the connecting plate 2. The cleaning mechanism 5 can be used to clean the side wall of the roller 4 to prevent too much dirt from remaining on the side wall of the roller 4. The cleaning mechanism 5 includes a support frame 51, which is symmetrically fixed to the surface of the fixing frame 1 in the front and rear directions. A rotating shaft 52 is rotatably connected between the two support frames 51. An assembly frame 53 is welded and fixed to the side wall of the rotating shaft 52. A scraper 54 is detachably fixed to the assembly frame 53 by fixing bolts and fixing nuts. The scraper 54 fits in contact with the side wall of the roller 4. During the rotation of the roller 4, the dirt on its surface is cleaned and removed by the scraper 54.

[0017] like Figure 2 As shown in the figure, the scraper 54 includes a scraper body 541, one end of the scraper body 541 is integrally formed with a connecting block 542, the connecting block 542 is used to be inserted into the assembly frame 53, and the other end of the scraper body 541 is integrally formed with a first blade portion 543 and a second blade portion 544. By setting a double scraping structure of the first blade portion 543 and the second blade portion 544, the scraping effect of the mud on the surface of the roller 4 is enhanced.

[0018] like Figure 1 and Figure 3 As shown in FIG, a limiting assembly 6 is fixedly assembled between the rotating shaft 52 and the fixing frame 1. The limiting assembly 6 can enhance the contact effect between the scraper 54 and the surface of the roller 4. When the scraper 54 is worn, the limiting assembly 6 can be used to rotate the rotating shaft 52 in the assembly frame 53 to adjust the angular position of the scraper 54 so that the scraper 54 remains in contact with the surface of the roller 4, thereby not affecting the cleaning effect.

[0019] The number of limit components 6 is two groups, which are symmetrically arranged between the rotating shaft 52 and the fixed frame 1 in the front and rear. The symmetrically arranged limit components 6 better drive the rotating shaft 52 to deflect the angle. The limit component 6 includes a limit frame 61, which is fixedly assembled on the surface of the fixed frame 1. An arc-shaped limit cavity 62 is provided in the limit frame 61. The arc-shaped design of the limit cavity 62 ensures that it is at the same center as the axis of the rotating shaft 52 to form a concentric circle structure. A sliding block 63 is slidably connected in the limit cavity 62, and the sliding block 63 is welded to the rotating shaft 52. A connecting shaft 64 is fixed to the connection, and an arc spring 65 is fixedly assembled in the limit cavity 62. The arc spring 65 is in a compressed state. By setting the elastic force generated by the arc spring 65 on the sliding block 63, the sliding block 63 can move in an arc shape along the limit cavity 62. During the movement of the sliding block 63 along the limit cavity 62, the rotating shaft 52 can drive the scraper 54 to deflect, maintaining the contact state between the scraper 54 and the surface of the roller 4. The side wall of the limit cavity 62 is provided with an open groove that passes through the limit frame 61, and the connecting shaft 64 can perform a stroke action along the open groove.

[0020] Working principle: During use, the device is dragged on the fixed frame 1 by an engineering vehicle, so that the roller 4 rotates in the fixed frame 1 to compact the roadbed. During the rotation of the roller 4, the scraper 54 of the cleaning mechanism 5 can clean the soil remaining on its surface to avoid the soil attached to the surface of the roller 4 affecting the compaction effect. After the scraper 54 is worn, it can be tightened by the limiting assembly 6 set between the rotating shaft 52 and the fixed frame 1 to keep the scraper 54 in contact with the roller 4 and maintain its effect of cleaning the soil.
