Description

Technical Field

[0001] This utility model relates to the field of compaction machine technology, and in particular to a protective ring for the roller of a municipal road subgrade compaction machine. Background Technology

[0002] A compactor is an engineering machinery used to compact materials such as soil, sand, gravel, asphalt, and concrete. It is widely used in road construction, water conservancy projects, building construction, mining engineering, and other fields. Its core function is to apply pressure to loose materials through mechanical force, reduce the voids inside the materials, and improve their density, strength, and stability.

[0003] In existing technologies, before laying the roadbed, the soil and gravel on the surface of the road surface need to be compacted by a compactor to reduce the voids between soil particles, enhance the density of the roadbed, and avoid problems such as settlement and deformation of the subsequent paving structure due to the loose foundation.

[0004] However, during the compaction process, due to the large size of the compactor, certain blind spots may occur. As a result, if there are animals on the road during the compaction process, the operator may find it difficult to spot and react in time, which could easily lead to the animals being crushed, injured, or even killed.

[0026] Example 1

[0027] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: a protective ring for a municipal roadbed compactor roller, including a protective mechanism 1, a dust-blocking mechanism 2 on one side of the protective mechanism 1, a protective frame 11, a side plate 12 at one end of the protective frame 11, a fixed connection between one end of the protective frame 11 and one side of the side plate 12, a connecting plate 13 on the inner surface of the side plate 12, a sliding connection between the inner surface of the side plate 12 and one end of the center of the connecting plate 13, a horizontal column 18 at one end of the connecting plate 13, and the connecting plate 13... One end of the connecting plate 13 is fixedly connected to one end of the horizontal column 18. A sub-rod 19 is provided on the inner wall of the horizontal column 18, and the inner wall of the horizontal column 18 is rotatably connected to one end of the sub-rod 19. A mother rod 110 is provided on one side of the sub-rod 19, and the side of the sub-rod 19 is rotatably connected to one side of the mother rod 110. A rake rod 111 is provided on the other side of the mother rod 110, and the other side of the mother rod 110 is fixedly connected to one end of the rake rod 111. A positioning hole 17 is provided on one side of the connecting plate 13, and a positioning rod 114 is provided on the inner surface of the positioning hole 17. The inner surface of 7 is slidably engaged with one end of the positioning rod 114. The outer side of one end of the positioning rod 114 is slidably connected to the inner wall of the protective frame 11. A second threaded rod 113 is provided on the inner wall of the protective frame 11. The inner wall of the protective frame 11 and the outer side of the second threaded rod 113 are rotatably connected through it. The outer side of the second threaded rod 113 is threadedly connected to the inner wall of one end of the positioning rod 114. A scraper is provided on the top side of the horizontal column 18. One end of the scraper is fixedly connected to the top side of the horizontal column 18. A concave plate 14 is provided at one end of the center of the connecting plate 13. One end of the rod 110 is rotatably connected to the top of the concave plate 14. A lead screw 16 is provided on the inner wall of the concave plate 14, and the inner wall of the concave plate 14 is threaded to the outer side of the lead screw 16. A support frame 15 is provided at the top of the lead screw 16, and the top of the lead screw 16 is fixedly connected to the middle of the support frame 15. One end of the support frame 15 is fixedly connected to one side of the side plate 12. A spring 112 is provided at one end of the female rod 110, and one end of the female rod 110 is fixedly connected to one end of the spring 112. The other end of the spring 112 is fixedly connected to the inner wall of the horizontal column 18.

[0028] In this embodiment, the protective ring for a municipal road subgrade compactor roller is used by installing protective frames 11 at both ends of the compactor roller. The protective frames 11 are L-shaped, and a side plate 12 is fixed to the shorter end. Connecting discs 13 are connected to the inner surfaces of both side plates 12. The connecting discs 13 can move up and down on the inner surfaces of the side plates 12. A horizontal column 18 is designed between the two connecting discs 13. A sub-rod 19 is rotatably connected to one inner wall of the horizontal column 18. The sub-rod 19 allows the rake rod 111 to move slightly left and right. The oscillation mechanism is designed with a mother rod 110 on the side of the sub-rod 19. There are multiple mother rods 110 with springs 112 between them. The mother rods 110 allow the rake rod 111 to swing up and down slightly. This way, when the compactor is working, if the road surface is uneven, the rake rod 111 will bend due to a hard collision with the ground. This method can play a buffering role. As the compactor moves forward, the rake rod 111 will contact small animals before the roller, preventing small animals from being crushed by the roller. The normal working rhythm of the compactor will not be affected by sudden obstacles.

[0029] A concave plate 14 is rotatably connected to one side of the connecting plate 13. A lead screw 16 is designed in the middle of the concave plate 14. A support frame 15 is rotatably connected to the top of the lead screw 16. The support frame 15 provides support for the concave plate 14. At the same time, rotating the lead screw 16 causes the concave plate 14 to move up from its original position, thereby changing the working height of the rake arm 111. In this way, when there are deep potholes or bumps on the road surface, the rake arm 111 can be raised or lowered by adjusting the lead screw 16 to ensure that it can always maintain a suitable contact distance with the road surface, so as to continuously play a buffering role when encountering uneven road sections.

[0030] A scraper is designed on the top side of the crossbar 18. When there is no obstruction, the scraper on the crossbar 18 comes into contact with the roller by rotating the connecting plate 13 ninety degrees. Since the connecting plate 13 has a positioning hole 17, after rotation, the positioning rod 114 on the protective frame 11 will correspond to the positioning rod 114. Then, by rotating the screw 113, the positioning rod 114 will be displaced from its original position and enter the positioning hole 17, thereby fixing the connecting plate 13. As the roller rolls, the scraper can efficiently scrape off the debris adhering to the roller surface, preventing the accumulation of these debris from affecting the compaction effect of the roller and keeping the roller clean at all times.

[0031] Example 2

[0032] like Figure 1 - Figure 5As shown, the dust blocking mechanism 2 includes a baffle 21, an inclined plate 22 is provided on the top side of the baffle 21, the top side of the baffle 21 is fixedly connected to the bottom side of the inclined plate 22, one side of the inclined plate 22 is fixedly connected to one side of the horizontal column 18, and one side of the horizontal column 18 is fixedly connected to one side of the baffle 21.

[0033] In this embodiment, a baffle 21 is fixed on one side of the horizontal column 18. The baffle 21 is located at the inner wall port of the horizontal column 18, and an inclined plate 22 is designed on one side of the baffle 21. The inclined plate 22 is triangular. After the horizontal column 18 rotates ninety degrees, it continuously scrapes away debris. Under the guidance of the inclined plate 22, the debris is transported to both ends of the roller. At the same time, the debris transported to both ends of the roller will naturally scatter on both sides of the roadbed and will not create new obstacles to the compaction operation of the roller. Thus, through the blocking of the baffle 21 and the guidance of the inclined plate 22, debris can be prevented from entering the inner wall of the horizontal column 18, which would prevent the rake 111 from making small-amplitude movements.

[0034] like Figure 1 - Figure 5 As shown:

[0035] During the operation of the compactor, if the road surface is uneven, the rake 111 will bend due to hard collision with the ground. This can play a buffering role. As the compactor moves forward, the rake 111 will contact small animals before the roller, preventing the small animals from being crushed by the roller. Since the rake 111 is installed in the crossbar, when the section of the road does not need to use the rake 111, the connecting plate 13 is rotated 90 degrees, so that the scraper on the crossbar 18 comes into contact with the roller. Since the connecting plate 13 has a positioning hole 17, after rotation, the positioning rod 114 on the protective frame 11 will correspond to the positioning rod 114. Then, by rotating the screw 113, the positioning rod 114 will be displaced in its original position and enter the positioning hole 17, thereby fixing the connecting plate 13. As the roller rolls, the scraper can efficiently scrape off the debris adhering to the roller surface.

[0036] By fixing a baffle 21 on one side of the horizontal column 18, and designing an inclined plate 22 on one side of the baffle 21, the inclined plate 22 is triangular. After the horizontal column 18 rotates ninety degrees, it continuously scrapes away the debris. Under the guidance of the inclined plate 22, the debris is conveyed to both ends of the roller, preventing the debris from entering the inner wall of the horizontal column 18 and causing the internal structure to be obstructed.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
