Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a crack sealing device for road construction. Background Technology

[0002] Road construction is an important part of transportation infrastructure construction. It involves multiple stages and complex technical requirements. With the acceleration of urbanization and the continuous growth of transportation demand, the technical level and quality requirements of road construction are also constantly improving. During the road construction process, it is necessary to comprehensively consider various factors such as geological conditions, environmental factors, and traffic flow to ensure construction quality and road safety.

[0003] During the long-term use of roads, cracks of varying degrees will appear on the road surface due to factors such as vehicle load and natural environment. If these cracks are not repaired in time, they will gradually expand, seriously affecting the safety and service life of the road. Traditional road crack repair methods mostly use manual hand-held crack filling guns, which is labor-intensive, time-consuming and labor-intensive for workers. Therefore, a crack filling device for road construction is proposed. Utility Model Content

[0015] This invention uses a motor to drive a connecting shaft, a driving bevel gear, a driven bevel gear, a rotating shaft, and a stirring rod to agitate the crack-sealing material and prevent it from clumping. A pump draws the crack-sealing material and pours it into the road cracks through a crack-sealing pipe. An electric cylinder's piston rod extends, moving a V-shaped scraper downwards until it touches the ground. A spring is compressed, and under the spring's elastic force, the V-shaped scraper remains in contact with the ground.
