Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering, in particular to a debris-clearing component for an asphalt crack repairing device. Background Art

[0002] With the development of society, the road surfaces are now basically paved with asphalt. Compared with other roads, asphalt pavement has the advantages of long service life, convenient construction, good waterproof performance, strong freeze-thaw resistance, etc. However, during the long-term use of asphalt pavement, cracks are prone to appear on the pavement. In order to repair the cracks, asphalt crack repair devices are often used;

[0003] The existing document with publication number CN220685738U discloses an asphalt pavement crack repair device, comprising a base and a feeding mechanism fixed on the base, wherein the base is connected to an angle adjustment mechanism on a side away from the feeding mechanism, and the angle adjustment mechanism comprises two fixed seats fixedly connected to the base and symmetrically, and an arc rod fixedly connected to the two fixed seats at both ends;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned asphalt pavement crack repair device also has a crack cleaning mechanism fixed on its base, and the crack cleaning mechanism includes an air compressor fixedly connected to the side of the base adjacent to the feeding mechanism, an exhaust head fixedly connected to the side of the base adjacent to the angle adjustment mechanism, and a gas pipeline connecting the output end of the air compressor to the exhaust head, and a heating element is provided at the outlet of the exhaust head, and the airflow discharged by the air compressor and the exhaust head is used to clean up debris, dust and other debris in the cracks. However, since the exhaust head is fixedly installed on the base, it is inconvenient to adjust the position of the exhaust head, and the cracks in the asphalt pavement are generally irregular in shape, so that the exhaust head cannot accurately blow air to the cracks;

[0006] 2. The above-mentioned asphalt pavement crack repair device also has a crack cleaning mechanism fixed on its base, and the crack cleaning mechanism includes an air compressor fixedly connected to the side of the base adjacent to the feeding mechanism, an exhaust head fixedly connected to the side of the base adjacent to the angle adjustment mechanism, and a gas pipeline connecting the output end of the air compressor to the exhaust head, and a heating element is provided at the outlet of the exhaust head. The airflow discharged from the air compressor and the exhaust head is used to clean up debris, dust and other debris in the cracks, but the discharged airflow cannot clean up larger pieces of gravel stuck in the cracks, so that the staff needs to manually clean up the larger pieces of gravel.

[0007] To this end, we provide a debris removal component for an asphalt crack repair device to solve the above-mentioned problems. Utility Model Content
