Description

Technical Field

[0001] The present application relates to the technical field of road rollers, and in particular to a construction device for filling roadbed in a goaf area of ​​a highway. Background Art

[0002] Highway goaf refers to an engineering measure taken during highway construction to make full use of underground resources. During highway construction, if there is a goaf in the ground, roadbed filling is required to ensure the stability and safety of the highway. Roadbed filling is to fill the goaf with soil or other materials to build the highway roadbed.

[0003] A road roller is a commonly used equipment in roadbed filling construction. A Chinese patent with the authorization number CN 219709995 U discloses a vibratory road roller, which can clean the roller in time when compacting different types of ground through a pressing plate and a cleaning brush to prevent mud or sand from sticking to the roller and causing the compacted ground to be uneven. However, the device does not process the mud on the roller after scraping it off with a scraper. The mud easily falls onto the roadbed, resulting in too much mud at that part of the roadbed, causing the roadbed at that position to be not flat enough after compaction. Utility Model Content

[0031] The bottom of the collecting box 7 is open, and a socket is provided at the bottom of the front side of the collecting box 7 and passes through the back side of the collecting box 7, and a supporting plate 9 is inserted into the inner cavity of the socket. The supporting plate 9 is provided to support the soil falling into the collecting box 7, and at the same time, the supporting plate 9 can be pulled out to clean the soil in the collecting box 7.

[0032] The bottom of the supporting plate 9 is fixedly connected to the limiting block 10, and the back of the collecting box 7 is provided with an avoidance opening for the passage of the limiting block 10. The front inner wall of the collecting box 7 is provided with a limiting groove 11 adapted to the limiting block 10, and the front of the supporting plate 9 is fixedly connected with a handle 12. By setting the limiting block 10, the limiting groove 11 and the handle 12, the supporting plate 9 is prevented from being separated from the slot, and the supporting plate 9 and the limiting block 10 are driven to move by pulling the handle 12 outward. During the movement, with the cooperation of the jack, the soil falling on the supporting plate 9 is scraped off to clean the collecting box 7. By setting the limiting block 10, when the limiting block 10 is fully embedded in the limiting groove 11, the end of the supporting plate 9 is flush with the inner wall of the collecting box 7, so that the soil on the supporting plate 9 can be completely cleaned.

[0033] A cleaning member fitted with the scraper 6 is provided above the scraper 6, and a driving unit is provided on the inner wall of the mounting frame 3. The driving unit drives the cleaning member to intermittently clean the dirt on the scraper 6. The driving unit is provided to drive the cleaning member to move and clean the dirt on the scraper 6.

[0034] The driving part includes a rotating roller 13 rotatably connected to the inner wall of the mounting frame 3. There are two rotating rollers 13. The surfaces of the two rotating rollers 13 are provided with the same transmission belt 14. The two rotating rollers 13 are connected through the transmission belt 14. The cleaning member is installed on the surface of the transmission belt 14. One of the rotating rollers 13 rotates, and then the transmission belt 14 is driven to move with the cooperation of the other rotating roller 13, thereby driving the cleaning member to move to clean the dirt on the scraper 6 to avoid blockage caused by dirt sticking to the scraper 6.

[0035] The inner wall of the mounting frame 3 is provided with a groove, and the inner wall of the groove is rotatably connected with a gear 15, the gear 15 is fixedly connected to one end of one of the rotating rollers 13, the side of the pressure roller 5 is fixedly connected with an arc-shaped tooth block 16, the arc-shaped tooth block 16 is meshed with the gear 15, and the inner wall of the mounting frame 3 is provided with an avoidance groove 17 for the passage of the arc-shaped tooth block 16, the arc-shaped tooth block 16 is driven to rotate by the pressure roller 5, and then the gear 15 is driven to rotate, and one of the rotating rollers 13 is driven to rotate by the gear 15.

[0036] The cleaning member includes a limit frame 18 fixedly connected to the transmission belt 14, and the inner wall of the limit frame 18 is slidably connected to a sliding plate 19. A spring 20 is arranged in the limit frame 18, and one end of the spring 20 is fixedly connected to the inner wall of the limit frame 18, and the other end of the spring 20 is fixedly connected to the sliding plate 19. By setting the limit frame 18 and the sliding plate 19, the cleaning member can adapt to the width between the transmission belt 14 and the pressure roller 5. By setting the spring 20, pressure can be generated on the sliding plate 19 so that the sliding plate 19 is close to the scraper 6.

[0037] The scraper 6 is tilted, and the horizontal surface of the transmission belt 14 is parallel to the scraper 6. The scraper 6 is tilted to facilitate the transportation of soil thereon, and the conveyor belt is set on the flat plate of the scraper 6 to facilitate the cleaning of the scraper 6 by a cleaning piece.

[0038] Working principle: When the highway goaf area roadbed filling construction device is used, the tractor 1 moves to make the roller 5 rotate to compact the filled roadbed. In this process, the scraper 6 scrapes off the soil adhering to the surface of the roller 5 when the roller 5 rotates. At the same time, the scraper 6 sends the soil into the collecting box 7 through the discharge port 8 to prevent it from falling on the roadbed and affecting the flatness of the roadbed. At the same time, the roller 5 drives the arc-shaped tooth block 16 to rotate, the arc-shaped tooth block 16 drives the gear 15 to rotate, the gear 15 drives one of the rotating rollers 13 to rotate, and then the other rotating roller 13 is rotated. The driving belt 14 is driven to move by the cooperation of the movable roller 13, and the driving belt 14 drives the cleaning part to move to clean the mud on the scraper 6 to avoid blockage caused by mud sticking to the scraper 6. When the mud in the collecting box 7 needs to be cleaned, the user pulls the handle 12 outward to drive the supporting plate 9 and the limit block 10 to move. During the movement, with the cooperation of the socket, the mud fallen on the supporting plate 9 is scraped off, and the collecting box 7 is cleaned, thereby making it impossible to collect the mud scraped off in the prior art of the highway goaf roadbed filling construction device, which easily affects the flatness of the roadbed.
