Description

Technical Field

[0001] The utility model belongs to the technical field of road crack filling, and in particular relates to a road crack filling device. Background Art

[0002] After long-term use, cracks will inevitably appear on the road surface. Such cracks are caused by the expansion and contraction of the road surface due to temperature fluctuations or uneven stress. These cracks allow water to penetrate into the roadbed, causing the road surface material to lose its structural integrity. If the cracks are not repaired and sealed in time, they will continue to grow, causing deformation of the road surface, potholes, and complete damage to the road surface. Therefore, it is necessary to repair early damage to the road, especially to repair cracks and potholes, which can extend the service life of the road.

[0003] Most existing caulking devices directly fill the cracks with cement or asphalt when caulking and repairing. If the cracks are not cleaned, there may be a lot of dust attached. If the cracks are directly caulked, it will affect the adhesion between the caulking material and the gap, and it may crack again later. Later, a caulking device that can clean the cracks appeared. The device blows the cracks through a blower nozzle to clean the impurities in the cracks, but there are still problems. During the blowing process, the gas will blow the dust everywhere, the working environment is poor, and it affects the sight of the staff. In addition, the blown dust will fall to the cleaned position, resulting in poor cleaning effect. Utility Model Content

[0033] A hollow tube 53 is provided at the rear of the discharge pipe 15, and an adjusting rod 39 is movably inserted in the hollow tube 53. A threaded hole is opened on the side wall of the hollow tube 53, and a locking bolt 55 is installed in the threaded hole. The end of the locking bolt 55 is against the adjusting rod 39; a scraper 37 is provided on the front side of the adjusting rod 39.

[0034] Two slide plates 56 are slidably connected to the top of the scraper 37, and a limit plate 38 is connected to the slide plate 56, and the limit plate 38 fits the scraper 37; a bidirectional screw 40 is rotatably connected to the adjusting rod 39, and the two slide plates 56 are respectively connected to the two ends of the bidirectional screw 40 by threads.

[0035] An ear plate 57 is provided at one end of the scraper 37, and a stop bolt 42 is threadedly connected to the ear plate 57. The end of the stop bolt 42 is rotatably connected to a stop plate 41 that cooperates with the bidirectional screw 40. The stop plate 41 is arc-shaped and has an anti-slip pad on the inner side.

[0036] During operation, the air pump 19 is turned on to clean the cracks by blowing through the nozzle 21. The first motor 26 is turned on to drive the incomplete gear 25 to rotate. When the toothed surface of the incomplete gear 25 meshes with the gear 24, the incomplete gear 25 drives the gear 24 and the nozzle 21 to rotate. When the toothless surface of the incomplete gear 25 is opposite to the gear 24, the nozzle 21 rotates in the opposite direction and resets under the rebound action of the torsion spring 23, thereby realizing the reciprocating rotation of the nozzle 21 within a certain angle, thereby expanding the cleaning range and improving the blowing efficiency and cleaning effect.

[0037] The dust cover 27 covers the blown dust inside it, and under the suction of the air inlet end of the air pump 19, the air mixed with dust in the dust cover 27 is sucked into the first chamber 47 of the filter box 32, and the air filtered by the first dust net 33 enters the first chamber 48, and then enters the air pump 19 through the air inlet pipe 36 to participate in the blowing operation. The top of the dust cover 27 is provided with an air inlet hole 45 and a second dust net 28 to ensure that sufficient air enters the dust cover 27 and prevent the dust inside the dust cover 27 from flowing out.

[0038] The first dustproof net 33 is circular. When the airflow passes through the fan blade 35, the fan blade 35 is driven to rotate, and the fan blade 35 drives the first brush rod 34 to rotate through the rotating shaft 46 to clean the first dustproof net 33 to prevent the mesh from being blocked. The cleaned dust falls into the inclined bottom plate 50 below and slides to the bottom end of the bottom plate 50. A baffle 49 is provided above the bottom plate 50 to prevent the dust on the bottom plate 50 from being lifted up. After all the operations are completed, the box door 59 is opened to clean the dust collected on the bottom plate 50.

[0039] The second dustproof net 28 is rectangular. During the reciprocating rotation of the nozzle 21, the connecting rod 30 is driven to reciprocate, thereby driving the second brush rod 29 to reciprocate on the guide rail 31 through the slider 51 to clean the second dustproof net 28 to prevent the mesh from being blocked. The cleaned dust enters the filter box 32 with the air flow. During the reciprocating movement of the second brush rod 29, the slider 51 slides adaptively in the slide groove 52.

[0040] As the personnel push the vehicle body 16 forward through the handrail 18, the cracks on the road surface are blown away and then the caulking mechanism caulks the cracks. The second motor 12 drives the stirring shaft 58 and the stirring frame 13 to rotate, stirring the caulking material in the storage tank 11 to prevent solidification. The pump body 14 is turned on, and the caulking material flows out to the gap through the discharge pipe 15 to fill the gap.

[0041] As the vehicle body 16 moves forward, the scraper 37 scrapes off the excess caulking material at the top of the gap, making the caulking smooth and beautiful. The limit plates 38 on both sides of the scraper 37 collect the scraped caulking material together to prevent the caulking material from flowing around. The spacing between the two limit plates 38 can be adjusted according to the width of the crack. When adjusting, loosen the stop bolt 42 to separate the stop plate 41 from the bidirectional screw 40, and screw the bidirectional screw 40. Under the action of the bidirectional thread, the two slide plates 56 drive the two limit plates 38 to move toward or away from each other, thereby adjusting the spacing between the limit plates 38. After the adjustment is completed, tighten the stop bolt 42 to make the stop plate 41 close to the bidirectional screw 40 to prevent the bidirectional screw 40 from rotating automatically during the operation. The height of the scraper 37 is also adjustable. Before operation, loosen the locking bolt 55 so that the adjusting rod 39 can move in the hollow tube 53, thereby adjusting the height of the scraper 37 so that the scraper 37 fits the ground, and then tighten the locking bolt 55. The locking bolt 55 presses against the adjusting rod 39 to lock the adjusting rod 39.
