Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to an asphalt repair machine for municipal roads. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt pavement has the advantages of good flatness, low noise and high driving comfort. It is widely used in municipal highway engineering construction. However, due to large traffic volume, high speed and overloading, the pavement is prone to damage after a period of use. For local damage to asphalt pavement, asphalt materials are generally used to repair it. Since there are many forms of damage to asphalt pavement, asphalt materials are generally used to fill cracks. However, some cracks are small in width and cannot be directly filled. A cutting machine must be used to expand and clean the cracks before filling can be performed. Generally, the original asphalt layer will be milled and excavated, and then asphalt materials are used for repair.

A vertically arranged mixing motor is installed in the center of the cover plate. A feed hopper is provided on the top of the cover plate and on one side of the mixing motor.

[0004] In the above technology, the asphalt comes out from the discharge pipe at the bottom of the mixing tank and is finally compacted by a compaction roller. However, the asphalt is not smoothed and trimmed after it is repaired to the road surface. The repair area may be uneven, affecting the flatness of the road surface. The thickness and distribution of the asphalt cannot be evenly controlled. The repair details need to be improved, so innovation is made in this technology. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the utility model provides a technical solution for an asphalt patching machine for municipal roads: Example 1:

[0023] like Figure 1-3 As shown, an asphalt patching machine for municipal roads includes a patching machine body 1, a mixing tank 2, two support frames 3 and a cutting knife 4. The mixing tank 2 is arranged on the top of the patching machine body 1, the two support frames 3 are respectively arranged on one side of the top of the patching machine body 1, and the cutting knife 4 is arranged between the two support frames 3. A discharge pipe 5 is provided at the bottom of the patching machine body 1, and two arc frames 6 are fixedly installed on the top of the patching machine body 1.

A convex plate 11 is provided at the bottom of the patching machine body 1, and a scraper 14 is provided at the bottom of the convex plate 11, which can be scraped flat according to the thickness of the asphalt patch. The scraper 14 helps to evenly distribute the asphalt in the cracks and potholes, ensure that the filling material is flush with the surrounding road surface, avoid excessive material seeping out of the cracks, and improve the flatness of the asphalt patch of the patching machine. Example 2:

[0024] Based on the first embodiment, Figure 1 and Figure 4 As shown, side blocks 12 are provided on both sides of the convex plate 11, a torsion rod 13 is provided between the inner walls of the two side blocks 12, and a scraper 14 is sleeved on one end of the torsion rod 13. Cross bars 15 are provided on both sides of the two arc frames 6, and concave holes are provided on both sides of the two displacement blocks 8. The utility model is an asphalt patching machine for municipal roads. By setting up the arc frame 6, cross bars 15, positioning holes 16 and concave holes, after the bottom surface of the scraper 14 contacts the filled asphalt, the operator sequentially embeds one end of the two cross bars 15 into the inside of the concave hole and the positioning hole 16, and the three continue to be threadedly connected, so that the arc frame 6 and the displacement block 8 can be limited and fixed.

[0025] Working principle: Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed into mineral materials. Asphalt pavement has the advantages of good flatness, low noise, and high driving comfort. It is widely used in municipal highway engineering construction. However, due to large traffic volume, high speed and overloading, the road surface is prone to damage after a period of use. Asphalt materials are generally used to repair local damage to asphalt pavement. Since there are many forms of damage to asphalt pavement, asphalt materials are generally used to fill cracks. However, some cracks are small in width and cannot be directly filled. They need to be expanded and cleaned with a cutting machine before filling. The original asphalt layer is generally milled and excavated, and then asphalt materials are used for repair. In the above technology, the asphalt comes out from the discharge pipe 5 at the bottom of the mixing tank 2, and is finally compacted by a compacting roller. However, the asphalt is not smoothed and trimmed after being repaired to the road surface. The repair area may be uneven, affecting the flatness of the road surface. The thickness and distribution of the asphalt cannot be evenly controlled. The repair details need to be improved. Therefore, When the cutting blade 4 rotates, the original asphalt layer is milled and excavated. Then, the repair body 1 is moved to the milling and excavation position, the discharge pipe 5 is aligned with this position, and the asphalt material inside the mixing tank 2 flows out from the discharge pipe 5. Since the two displacement blocks 8 can move up and down freely at one end of the corresponding support rod 7, the two displacement plates 9 are connected with the convex plate 11, which will drive the scraper 14 to move up and down synchronously. Therefore, the position height of the scraper 14 can be adjusted, and the asphalt repair can be leveled according to its thickness. The scraper 14 helps to smooth the asphalt. The green is evenly distributed in the cracks and potholes, ensuring that the filling material is flush with the surrounding road surface, avoiding excessive material seepage from the cracks, and improving the flatness of the asphalt repair by the patching machine. After the bottom surface of the scraper 14 contacts the filled asphalt, the operator embeds one end of the two cross bars 15 into the concave hole and the positioning hole 16 in turn, and the three continue to be threaded together, so that the arc frame 6 and the displacement block 8 can be limited and fixed, ensuring the stability of the convex plate 11. The pressure of the scraper 14 and the asphalt is moderate, which can maintain the stability of the scraper 14.
