Description

Technical Field

[0001] The utility model relates to the technical field of road asphalt, in particular to a road asphalt flattening device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid and an organic cementitious material with waterproof, moisture-proof and anti-corrosion properties. Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed into mineral materials. Currently, when paving asphalt, a special flattening device is required to ensure the paving effect.

[0003] An asphalt concrete flattening device for highway construction disclosed in the Chinese utility model patent application disclosure CN215925531U has a fixed plate fixedly installed inside a processing box. Through the linkage structure formed by the fixed plate, connecting rod, limit plate and limit block, the rotation of the connecting rod causes the limit plate and the mixing rod to shake. The mixing rod can not only rotate on itself but also revolve, thereby improving the mixing effect of the asphalt and facilitating the rapid falling of the asphalt. However, the existing road asphalt flattening device has a relatively simple structure and a relatively large body. When encountering a narrow road, the asphalt cannot be flattened at the gap between the two sides of the body and the two sides of the road. The device needs to be moved repeatedly to flatten it, which reduces the overall work efficiency. Utility Model Content

The two ends of the limit rod 8 are fixedly connected to the sliding seat 4, and the outer surface of the limit rod 8 is slidably connected to the sliding block 9, so that the sliding block 9 drives the connecting seat 11 to move back and forth. The side surface of the sliding block 9 is fixedly connected to the sawtooth 10, and the outer surface of the sawtooth 10 is meshed with the gear 6. The rotation of the gear 6 can drive the sawtooth 10 and the sliding block 9 on both sides to move in different directions, thereby driving the two groups of flattening devices 7 to extend outward, so as to flatten the spacing position between the narrow road and the sides of the vehicle body 1, increase the convenience of use, and improve work efficiency. The lower surface of the sliding block 9 is fixedly connected to the connecting seat 11, and the side surface of the connecting seat 11 is fixedly connected to the second motor 12.

The fixed seat 14 is internally rotatably connected to the rotating shaft 15. One end of the rotating shaft 15 is fixedly connected to a worm gear 16. The outer surface of the rotating shaft 15 is fixedly connected to a rotating block 17. The side surface of the rotating block 17 is fixedly connected to a stone shoveling box 18 for shoveling away stones or obstacles on the road surface ahead to avoid affecting the rolling of the road asphalt by the flattening roller 13.
