A reduction motor with an output shaft fixedly connected to the rear of the rear first support rod is also fixedly connected to the rear end of the leveling roller. The reduction motor drives the leveling roller to rotate. This invention, through a series of structural designs, can level and compact asphalt pavements. It can effectively scrape and collect asphalt adhering to the leveling roller during leveling, effectively reducing the occurrence of asphalt falling onto the leveled pavement and causing bumps, thus improving leveling stability. After leveling, the collection box can be easily removed by pulling to clean the asphalt inside. Furthermore, it can perform weighted compaction operations according to the road conditions during compaction, improving its flexibility.

[0004] The analysis of the above technical solutions shows that, because the collection box and the operating components are both located in the middle of the device, personnel need to operate in the middle of the device when cleaning the asphalt inside the collection box. This also requires frequent disassembly and reassembly, causing inconvenience in practical use. Therefore, we provide an asphalt pavement leveling device to solve these problems.

[0022] 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.

[0023] like Figure 1-7As shown, this embodiment proposes an asphalt pavement smoothing device, including a mounting frame 1 and a pressure roller 2. A scraper 6 is provided on the right side of the pressure roller 2, and two mounting shafts 9 are fixedly connected to the scraper 6. Two positioning mechanisms are provided on the inner wall of the mounting frame 1, and the scraper 6 is detachably connected to the positioning mechanisms through the mounting shafts 9. The scraper 6 is located on the right side of the pressure roller 2, so it can directly scrape off the asphalt adhering to the pressure roller 2. The pressure roller 2 moves to the left when it moves. Two base plates 12 are fixedly connected to the bottom surface of the mounting frame 1, and a collection frame 5 is rotatably arranged between the two base plates 12. The collection frame 5 is located directly below the scraper 6. A restraint for the collection frame 5 is provided on the front of the mounting frame 1. With the aforementioned structure, the rotating limiting mechanism can scrape off the asphalt adhering to the surface of the pressure roller 2 using the collection frame 5, allowing the scraped asphalt to fall into the collection frame 5 for collection. Furthermore, the scraper plate 6 and the collection frame 5 are separate units, making them more flexible and convenient to use. When cleaning the asphalt collected by the collection frame 5, it is not necessary to remove the collection frame 5; simply release the restriction on the rotation of the collection frame 5 through the limiting mechanism, and then rotate the collection frame 5 180° to pour out the asphalt. This makes operation more convenient for personnel, eliminating the need for repeated disassembly and reassembly of the collection frame 5. The machinery, parts, and equipment in this device all adopt conventional models found in existing technology, and will not be described in detail here.

[0024] like Figure 1 As shown, the positioning mechanism includes a positioning block 10 and two base plates 12. The telescopic ends of the two base plates 12 are connected to the right side of the positioning block 10, and the fixed ends of the two base plates 12 are fixed to the inner wall of the mounting frame 1, allowing the positioning block 10 to be pushed and moved by the telescopic ends of the two base plates 12. The right end of the mounting shaft 9 is inserted into the middle of the positioning block 10. A screw 11 is threaded onto the positioning block 10, and the bottom end of the screw 11 contacts the surface of the mounting shaft 9. A first spring 13 is sleeved on the surface of each of the two base plates 12, and the two ends of the first spring 13 are respectively fixed to the inner wall of the mounting frame 1 and the surface of the positioning block 10. With the above structure, the scraper plate 6 can be easily disassembled. In specific operation, the two mounting shafts 9 on the scraper plate 6 are respectively inserted into the two base plates 10. Within the positioning block 10, the scraper 6 can be initially positioned. Then, the distance between the scraper 6 and the pressure roller 2 is adjusted so that the bottom end of the scraper 6 slides on the surface of the pressure roller 2. Finally, the two screws 11 are rotated so that the bottom end of the screws 11 presses against the surface of the mounting shaft 9, thereby pressing and fixing it within the positioning block 10 to prevent the scraper 6 from slipping off. Removing the scraper 6 is also more convenient. Simply rotate the two screws 11 to release the fixing of the mounting shaft 9, then slide one of the positioning blocks 10 to the right to disengage the corresponding mounting shaft 9 from the positioning block 10. Then, move the other positioning block 10 to the right so that both mounting shafts 9 disengage from the positioning block 10. The scraper 6 can then be removed from the right side of the pressure roller 2. The operation is more convenient and flexible.

[0025] like Figures 1 to 4 and Figure 7 As shown, a liquid storage hopper 3 is fixedly connected to the scraper plate 6, and a drain pipe 8 is fixedly connected to the right end of the scraper plate 6. The bottom end of the liquid storage hopper 3 is connected to the drain pipe 8 through several liquid delivery pipes. Several drippers are connected to the bottom surface of the drain pipe 8, and the drippers are close to the right side of the scraper plate 6. The liquid storage hopper 3 contains lubricating oil. The drippers are existing mature structures and will not be described in detail here. With the above structure, the lubricating oil in the liquid storage hopper 3 can be gradually dripped onto the right side of the scraper plate 6 by each dripper, thereby preventing asphalt from adhering to the right side of the scraper plate 6 and facilitating the removal of asphalt from the surface of the pressure roller 2 from the scraper plate 6.

[0026] like Figure 2 and Figure 6 As shown, both ends of the collection frame 5 are fixedly connected to a rotating shaft 7, and the two rotating shafts 7 are respectively rotatably set in the two base plates 12. With the setting of the two rotating shafts 7, the collection frame 5 can be rotated between the two base plates 12, so as to more conveniently switch the collection or unloading of the collection frame 5.

[0027] like Figure 6 As shown, the limiting mechanism includes a fixed plate 15 and an I-shaped tie rod 17. The fixed plate 15 is fixed to the front of the mounting bracket 1. The I-shaped tie rod 17 is disposed through the middle of the fixed plate 15. A retaining plate 14 is fixed to the bottom end of the I-shaped tie rod 17. A retaining groove 18 is provided on the rotating shaft 7, and the retaining plate 14 is inserted into the retaining groove 18. A second spring 16 is sleeved on the surface of the I-shaped tie rod 17. The two ends of the second spring 16 are respectively fixed to the bottom end of the I-shaped tie rod 17 and the bottom surface of the fixed plate 15. With the above structure, the retaining plate 14 is inserted into the retaining groove 18 to limit the rotation of the rotating shaft 7, thereby... To prevent the aggregate frame 5 from rotating freely between the two base plates 12, and to ensure that the base plates 12 can properly collect the asphalt blocks scraped off from the scraper plate 6, when it is necessary to clean the asphalt blocks in the aggregate frame 5, simply pull the I-shaped pull rod 17 upwards to release the clamping plate 14 from limiting the clamping slot 18. Then, the personnel can rotate the aggregate frame 5 180° to pour out the asphalt blocks collected in the aggregate frame 5 without having to disassemble it as a whole, making the operation more flexible and convenient. After the aggregate frame 5 is flipped downwards, the clamping plate 14 can also be used to insert and limit the rotating shaft 7, so that the aggregate frame 5 will not shake randomly during unloading.

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, a cover plate 4 is hinged to the liquid storage hopper 3. The cover plate 4 prevents impurities floating in the air from entering the liquid storage hopper 3, thereby avoiding blockage in the liquid storage hopper 3 and ensuring normal dripping from the dripper at the bottom of the drain pipe 8.

[0029] The working principle and usage process of this utility model are as follows: When the pressure roller 2 begins to level the asphalt road surface, lubricating oil is poured into the storage hopper 3 in advance, and the cover plate 4 is placed on top to prevent impurities from entering the storage hopper 3. Then, the lubricating oil is gradually dripped onto the right side of the scraper plate 6 using the drip nozzle at the bottom of the drain pipe 8 to prevent asphalt from adhering to the scraper plate 6. Then, the bottom end of the scraper plate 6 will scrape off the asphalt adhering to the surface of the pressure roller 2 and collect it into the collection frame 5. When the pressure roller 2 completes the leveling work of the road surface, and it is necessary to clean the asphalt blocks in the collection frame 5, simply pull the I-shaped pull rod 17 upward to release the clamping plate 14 from the clamping groove 18. Then, the personnel can rotate the collection frame 5 180° to remove the asphalt blocks in the collection frame. The asphalt blocks collected in the collection frame 5 can be poured out without disassembling the entire frame, making the operation more flexible and convenient. After the collection frame 5 is flipped downwards, the clamping plate 14 can be used to insert and limit the rotating shaft 7, so that the collection frame 5 will not shake during unloading. When the scraper 6 needs to be removed for maintenance, the operator only needs to operate at both ends of the pressure roller 2, making the operation more convenient. Rotate the two screws 11 to release the fixing of the mounting shaft 9, and then slide one of the positioning blocks 10 to the right to disengage the corresponding mounting shaft 9 from the positioning block 10. Then move the other positioning block 10 to the right to disengage both mounting shafts 9 from the positioning blocks 10, and the scraper 6 can be removed from the right side of the pressure roller 2. The operation is more convenient and flexible.
