Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, specifically a double steel drum road roller with a scraper structure. Background Technology

[0002] Road rollers fall under the category of road and bridge engineering equipment in construction machinery. They are widely used in filling and compaction operations for large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers.

[0003] When compacting asphalt concrete pavement with a road roller, asphalt and impurities easily adhere to the soft asphalt pavement during the initial compaction by the front steel wheel. Existing cleaning methods involve using scrapers to collect the adhering impurities, followed by a brush structure to collect the scraped impurities. However, existing brush components require a separate drive system, which not only increases the complexity of the equipment but also makes it difficult to accurately match the equipment's movement speed, further increasing the difficulty of operation for workers. Therefore, it is necessary to develop a new type of double steel wheel press with a scraping structure to address the shortcomings of existing technologies. Utility Model Content

[0010] Preferably, the linkage component includes a third pulley that is sleeved on the lower end of the secondary transmission belt. The front sides of the third pulley, the first pulley, and the second pulley are all integrally formed with anti-detachment blocks, which are attached to the front sides of the primary and secondary transmission belts.

[0011] Preferably, a linkage sleeve is sleeved on the rear end of the outer surface of the third pulley, and a positioning bearing is rotatably sleeved on the outer surface of the linkage sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Due to the transmission component, the sweeping roller rotates rapidly following the front pressure roller, thereby sweeping the impurities scraped off by the scraper and falling to the ground into the collection bin. Moreover, the transmission component ensures that the rotational speed of the sweeping roller is always greater than that of the front and rear pressure rollers, so that the sweeping roller moves along the ground while having a significant relative rotation with the ground, thus quickly sweeping the impurities on the ground into the collection bin and effectively reducing the difficulty of operation.

[0015] 2.

Due to the linkage spring, this utility model can ensure that the third pulley can drive the sweeping roller to rotate through the rotating groove under the drive of the secondary transmission belt. At the same time, the sweeping roller is subjected to resistance, which can be buffered by the elastic action of the linkage spring, avoiding the impact on the rotation of the transmission component and the front pressure wheel. With the cooperation of the lifting component, it is also convenient for the sweeping roller to cross obstacles in time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5As shown, this utility model provides a double steel drum road roller with a scraper structure, including a road roller 1, a front roller 2 and a rear roller 3. The front roller 2 and the rear roller 3 are respectively connected to the front and rear ends of the road roller 1. The outer surface of the front roller 2 is fitted with a scraper 8 that is fixedly connected to the bottom of the road roller 1. The bottom of the road roller 1 is also equipped with a collection bin 4 and a sweeping roller 6. The two ends of the sweeping roller 6 are connected to lifting components 7. The top of the lifting components 7 is fixedly connected to the bottom of the road roller 1. The two ends of the sweeping roller 6 are connected to a transmission component 5 through the lifting components 7. The other end of the transmission component 5 is connected to the front roller 2 in a transmission connection.

[0025] The transmission assembly 5 includes a primary transmission belt 51 and a secondary transmission belt 52 disposed on the front and rear sides of the roller 1. The primary transmission belt 51 and the secondary transmission belt 52 are internally connected to a first pulley 53, a second pulley 54, and a linkage assembly 55. The outer diameter of the first pulley 53 and the second pulley 54 is larger than the outer diameter of the linkage assembly 55. Due to the arrangement of the transmission assembly 5, the sweeping roller 6 rotates rapidly following the front pressure roller 2, thereby sweeping the impurities scraped off by the scraper 8 and falling to the ground into the collection bin 4. Moreover, through the transmission of the transmission assembly 5, the rotation speed of the sweeping roller 6 is always greater than the rotation speed of the front pressure roller 2 and the rear pressure roller 3, so that the sweeping roller 6 moves along the ground while having a significant relative rotation with the ground, thereby quickly sweeping the impurities on the ground into the collection bin 4 and effectively reducing the difficulty of operation.

[0026] like Figure 3 As shown, the outer surface of the second pulley 54 and the front end of the outer surface of the first pulley 53 are connected to the interior of the first-stage transmission belt 51, and the rear end of the outer surface of the first pulley 53 and the front end of the outer surface of the linkage assembly 55 are connected to the interior of the second-stage transmission belt 52.

[0027] like Figures 1 to 3 As shown, the rear end of the first pulley 53 is fixedly connected to both ends of the front roller 2 and rotatedly sleeved inside the roller 1. The second pulley 54 is rotatedly sleeved to the front and rear ends of the roller 1 through bearings. The linkage component 55 is rotatedly sleeved inside the lifting component 7.

[0028] like Figure 3 As shown, the lifting assembly 7 includes a telescopic rod 71 disposed above the sweeping roller 6. A connector 72 is fixedly connected to the top of the telescopic rod 71, and the connector 72 is fixedly connected to the bottom of the road roller 1. A connecting frame 73 is fixedly connected to the bottom of the telescopic rod 71, and the sweeping roller 6 is movably installed inside the connecting frame 73. Due to the setting of the lifting assembly 7, the lifting height of the sweeping roller 6 can be controlled by the telescopic rod 71 in cooperation with the connector 72 and the connecting frame 73, thereby controlling the distance between the sweeping roller 6 and the ground, and ensuring that the height of the sweeping roller 6 can be adapted to the working state and working environment.

[0029] like Figure 4 and Figure 5 As shown, the linkage assembly 55 includes a third pulley 551 that is sleeved on the lower end of the secondary transmission belt 52. The front sides of the third pulley 551, the first pulley 53, and the second pulley 54 are all integrally formed with anti-detachment blocks 552, which are attached to the front sides of the primary transmission belt 51 and the secondary transmission belt 52. Due to the setting of the anti-detachment blocks 552, the primary transmission belt 51 and the secondary transmission belt 52 can be prevented from detaching from the first pulley 53, the second pulley 54, and the third pulley 551 during rapid movement, thereby ensuring the stability of the rapid transmission of the primary transmission belt 51 and the secondary transmission belt 52.

[0030] like Figure 4 and Figure 5 As shown, a linkage sleeve 553 is sleeved on the rear end of the outer surface of the third pulley 551. A positioning bearing 554 is rotatably sleeved on the outer surface of the linkage sleeve 553. The linkage sleeve 553 is rotatably sleeved inside the connecting frame 73 through the positioning bearing 554. The rear end of the anti-detachment block 552 extends into the interior of the connecting frame 73 and is fixedly connected to the end of the cleaning roller 6.

[0031] like Figure 4 and Figure 5 As shown, a rotating groove 555 is provided on the outer surface of the third pulley 551. The linkage sleeve 553 is rotatably engaged with the rear end of the third pulley 551 through the rotating groove 555. A linkage spring 556 is provided inside the rotating groove 555. One end of the linkage spring 556 is connected to the inner wall of the rotating groove 555, and the other end of the linkage spring 556 is connected to the inner wall of the linkage sleeve 553. Due to the setting of the linkage spring 556, under its elastic connection, it can ensure that the third pulley 551 can drive the sweeping roller 6 to rotate through the rotating groove 555 under the drive of the secondary transmission belt 52. At the same time, the sweeping roller 6 is subjected to resistance so that it can be buffered under the elastic action of the linkage spring 556, avoiding affecting the rotation of the transmission component 5 and the front pressure roller 2. At the same time, with the cooperation of the lifting component 7, it is also convenient for the sweeping roller 6 to cross obstacles in time.

[0032] Working principle and usage process of this utility model:

[0033] With the cooperation of the front roller 2 and the rear roller 3, the movement of the equipment is controlled by the roller 1. When the equipment moves, the front roller 2 rolls along the ground to compact the asphalt. Since the diameter of the first pulley 53 and the second pulley 54 sleeved in the primary transmission belt 51 is larger than the diameter of the first pulley 53 and the linkage component 55 sleeved in the secondary transmission belt 52, when the front roller 2 and the rear roller 3 roll along the ground, the sweeping roller 6 is driven to rotate by the transmission component 5, so that the sweeping roller 6 rotates rapidly relative to the ground, thereby sweeping the impurities into the collection bin 4.

[0034] Under the elastic connection of the linkage spring 556, when the secondary transmission belt 52 drives the third pulley 551 to rotate, it can indirectly drive the linkage sleeve 553 to rotate through the linkage spring 556, thereby driving the cleaning roller 6 to rotate.

[0035] At this time, the impurities adhering to the surface of the front pressure roller 2 are scraped off by the scraper 8 and fall to the ground. When the sweeping roller 6 passes by, with the cooperation of the transmission component 5, the rapidly rotating sweeping roller 6 can rotate rapidly relative to the ground, thereby sweeping the impurities it comes into contact with into the collection bin 4.
