Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to crack repairing equipment for highway construction and maintenance. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of the asphalt pavement itself belongs to the category of flexible pavement.

[0003] However, due to vehicle overloading and asphalt aging, asphalt pavements are prone to potholes and cracks. At this time, repair equipment is needed to refill the cracks in the pavement with asphalt for repair. In actual use, the repair of asphalt pavements is often done by hand or machine, and the discharge is uneven, and asphalt overflows frequently, resulting in waste. As a result, the repaired pavement is often slightly higher than the normal pavement. In addition, asphalt hardening may occur during construction, resulting in blockage at the discharge port. In order to solve the above problems, avoid affecting the flatness of the pavement after asphalt repair, and avoid affecting the discharge port after asphalt cooling, we have proposed a crack repair equipment for highway construction and maintenance.

After the asphalt is evenly stirred, the device is moved as a whole to the top of the crack to be repaired, and then the trigger button 15 on the push handle is pressed to trigger the control motor 14 to start. The rotation of the control motor 14 drives the blocking block 12 fixedly installed on the connecting shaft 13 to rotate along with the connecting shaft 13, thereby driving the blocking block 12 to tilt inside the discharge pipe 5. As the blocking block 12 tilts, its blocking area will become smaller, and the asphalt will pass through The asphalt falls from the inside of the discharge pipe 5 due to gravity, thus completing the discharge. Then, the control motor 14 is restarted by pressing the trigger button 15 to drive the material blocking block 12 to reset. After the asphalt falls, it is only necessary to push the device as a whole to make the rectifier plate 6 scrape from the accumulated asphalt, and then the asphalt will expand along the rectifier plate 6 on both sides until it contacts the side scraper 16.
