Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement construction, in particular to an asphalt pavement compacting device. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt pavement compaction is generally done by spreading the asphalt on the road with a paver, and then using double steel wheel rollers, vibratory rollers and other compaction machinery to repeatedly roll the asphalt to achieve the compaction degree required by the design. The traditional compaction method is for the roller to drive the compaction wheel to compact the asphalt pavement. When the compaction wheel is performing the compaction operation, the asphalt particles are easily adhered to the outer wall of the compaction wheel, making it impossible to evenly distribute the compaction force on the entire road surface, which in turn causes the road surface to become uneven or have inconsistent density.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 3As shown, an asphalt pavement compacting device includes a frame 1, a compacting roller 20 is rotatably connected to the frame 1, and a rotating shaft 2 is rotatably connected to both sides of the compacting roller 20 in the frame 1. A scraper 3 is fixedly connected to the side of the rotating shaft 2 close to the compacting roller 20 on both sides. The scraper 3 on both sides are arranged symmetrically with the center. The rotating shaft 2 on both sides extends to one end outside the frame 1 and is fixedly connected to a gear 4. The outer wall of the frame 1 is provided with an adjustment mechanism for driving the gears 4 on both sides to rotate synchronously. The outer wall of the frame 1 is slidably connected to a connecting rod 5. Both ends of the connecting rod 5 are fixedly connected to the rack 6 engaged with the gear 4. The outer wall of the frame 1 is provided with a control mechanism that drives the connecting rod 5 to slide. The control mechanism includes a slider 7 fixedly connected to the lower end of the connecting rod 5. The slider 7 is slidably connected to the outer wall of the frame 1. The outer wall of the frame 1 is rotatably connected to a screw 9. The slider 7 is threadedly connected to the outer wall of the screw 9. A motor 8 that drives the screw 9 to rotate is fixedly connected to the frame 1. A protective cover 17 that cooperates with the adjustment mechanism is provided on one side of the frame 1.

[0020] One side of the scraper 3 is fixedly connected to a suction cover 19, the upper end of the frame 1 is fixedly connected to a support plate 10, the support plate 10 is fixedly connected to a suction box 11, the bottom surface of the suction box 11 is fixedly connected to a high-pressure air pump 12, and suction hoses 13 are fixedly connected between both sides of the suction box 11 and the suction covers 19 on both sides. A filter screen 14 is provided on the bottom surface of the suction box 11, and support frames 16 cooperating with the suction hose 13 are fixedly connected on both sides of the suction box 11. A pull-out frame 15 is slidably inserted in the suction box 11, and a pulling hole 18 cooperating with the pull-out frame 15 is provided on the suction box 11, and the filter screen 14 is fixedly connected to the bottom surface of the pull-out frame 15.

[0021] In specific use, when the compacting roller 20 rolls and moves clockwise, the motor 8 is started to drive the screw 9 to rotate, and the screw 9 drives the slider 7 to slide along the outer wall of the frame 1. At the same time, the slider 7 drives the connecting rod 5 to slide to the side of the compacting wheel's forward direction, so that the racks 6 at both ends drive the gears 4 on both sides to rotate counterclockwise, and the gears 4 on both sides drive the rotating shafts 2 on both sides to rotate synchronously, so that the scraper hoppers 3 on both sides of the compacting wheel swing counterclockwise, and the scraper hopper 3 on one side swings to a state where the lower end is in contact with the outer wall of the compacting roller 20, so that the particles adhered to the outer wall of the compacting roller 20 during the rotation process are scraped off by the lower end of the scraper hopper 3 and remain in the scraper hopper 3, and the high-pressure air extraction is started. Pump 12, the raw material particles in the scraper hopper 3 enter the suction box 11 through the suction cover 19 and the suction hose 13 and fall into the upper end of the filter 14. When the compacting roller 20 rolls counterclockwise to perform the road compacting operation, the motor 8 is started to rotate in the opposite direction, driving the scraper 3 on both sides to swing in parallel, and the bottom surface of the scraper hopper 3 on the other side contacts the outer wall of the compacting roller 20 to perform the scraping operation. The compacting roller 20 in both directions of travel can be cleaned to prevent the particles on the outer wall of the compacting roller 20 from affecting the flatness of the subsequent compacting operation. When the waste needs to be cleaned, the pull-out frame 15 is pulled out to pull out the filter 14 and pour out the particles on the filter 14.
