Description

Technical Field

[0001] The utility model belongs to the technical field of road cutting seams, and particularly relates to a cutting seam device for asphalt road construction. Background Art

[0002] An asphalt pavement is formed by paving and rolling asphalt concrete to form various types of road surfaces. A roller is used to perform compaction operations on the asphalt pavement, causing the compacted asphalt pavement to undergo permanent deformation and become dense. When performing the paving work of asphalt concrete, longitudinal construction joints will occur at the road surface joints, and it is necessary to cut them neatly.

[0003] In the related art, an asphalt pavement cutting machine is disclosed. When the angle of the saw blade needs to be adjusted, the handwheel is rotated, and after the torque is reduced and amplified by the worm and worm gear reducer, the rotating shaft is driven to rotate. Since the lead screws Ⅰ and Ⅱ are arranged on the rotating shaft and the thread directions of the lead screws Ⅰ and Ⅱ are opposite, the wedge blocks Ⅰ and Ⅱ are synchronously driven to move relatively. Since the upper end surfaces of the wedge blocks Ⅰ and Ⅱ are inclined planes, when the wedge blocks Ⅰ and Ⅱ move inwards synchronously, they push the base plate to rotate upwards, realizing the adjustment of the saw blade angle.

[0004] However, there are still deficiencies in the above structure. During the cutting process of the cutting seam device, dust cannot be reduced, which easily causes excessive smoke and dust at the construction site, and it is not convenient to replace the cutting disc.

[0005] Therefore, it is necessary to provide a new cutting seam device for asphalt road construction to solve the above technical problems. Summary of the Utility Model
