Description

Technical Field

[0001] This utility model relates to the technical field of road and bridge construction equipment, and in particular to a pressure roller cleaning mechanism and a road surface compaction device. Background Technology

[0002] During road construction, road compaction equipment such as road rollers and rollers are typically used to compact the roadbed or pavement. During compaction, the rollers may adhere to soil or other paving materials as they travel. If not cleaned promptly, this can lead to unevenness in subsequent work. Current technologies typically employ cleaning mechanisms such as chains or scrapers for this purpose.

[0003] Chinese Patent Publication No. CN215210356U discloses a roadbed and pavement compaction device for road and bridge engineering. The device includes a pressure roller, with L-shaped fixing frames installed on the left and right sides of the top surface of a U-shaped fixing frame in front of the pressure roller. A fixed scraper fixedly installed at the top of the L-shaped fixing frame is rotatably connected to a vibrating plate via a first rotating shaft. The fixed scraper and the vibrating plate are respectively bonded to the upper and lower ends of a leak-proof cloth tape. The vibrating plate is rotatably connected to a connecting arm via a second rotating shaft and a rocker arm. The connecting arm is fixedly connected to a rotating shaft rotatably mounted on a connecting seat. A second helical gear installed at the middle of the rotating shaft meshes with a first helical gear on the front side. The first helical gear is fixedly mounted on the output shaft of a motor. The motor is fixedly mounted on the top surface of the L-shaped seat. The bottom side of the L-shaped seat is fixedly connected to the front end of a collection trough. The fixed scraper can scrape off foreign objects adhering to the surface of the pressure roller, which are then shaken off by the vibration of the vibrating plate and sent into the collection trough for collection, preventing foreign objects from falling back onto the ground and affecting the compaction quality. The aforementioned patent has a complex structure, and the gear transmission mechanism is easily affected by scraped material, which affects the transmission effect. In addition, the use of motor drive increases energy consumption and wiring difficulty. Utility Model Content

[0004] The main purpose of this utility model is to provide a pressure roller cleaning mechanism and a road compaction device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a pressure roller cleaning mechanism, including a scraper, a vibrating plate, a driven roller, and a collection trough. Two L-shaped mounting brackets are symmetrically arranged on one side of the collection trough. The scraper is fixedly installed between the two L-shaped mounting brackets, with its upper end abutting against the pressure roller. The upper end of the vibrating plate is hinged to the bottom of the scraper. A mounting plate is also provided on the side of the collection trough with the L-shaped mounting brackets. The driven roller is rotatably mounted on the mounting plate. A connecting plate is also provided at the end of the driven roller's shaft. An eccentric shaft is provided on the connecting plate, and a connecting rod is hinged to the eccentric shaft. The end of the connecting rod is hinged to the bottom of the vibrating plate. The driven roller abuts against the pressure roller.

[0006] Furthermore, the bottom of the L-shaped mounting bracket is provided with a strip-shaped hole.

[0007] Furthermore, both the scraper and the vibrating plate are inclined downwards.

[0008] Furthermore, the lower end of the vibrating plate is located inside the collection trough.

[0009] This utility model also provides a road compaction device, including the above-mentioned roller cleaning mechanism, and further including a support frame and a roller; the roller is disposed in the support frame, the roller cleaning mechanism is installed on the support frame, and the scraper and driven roller of the roller cleaning mechanism abut against the roller.

[0010] Furthermore, a fixing bolt is screwed onto the support frame, and the fixing bolt passes through the strip hole of the pressure roller cleaning mechanism.

[0011] This utility model has the following beneficial effects:

[0012] This utility model has a simple structure. The linkage motion mechanism is located below the scraper and the vibrating plate, so it is not affected by the scraped material. Moreover, the linkage motion mechanism does not require a separate power mechanism, which saves energy consumption. The scraped material is sent into the collection trough for collection, so as to avoid falling back onto the ground and affecting the compaction quality. Attached Figure Description

[0018] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0019] like Figure 1-3As shown, this utility model provides a pressure roller cleaning mechanism, including a scraper 1, a vibrating plate 2, a driven roller 6, and a collection trough 3. Two L-shaped mounting brackets 4 are symmetrically arranged on one side of the collection trough 3. The bottom of each L-shaped mounting bracket 4 has a slotted hole 5 for easy adjustment and installation. The scraper 1 is fixedly installed between the two L-shaped mounting brackets 4. The upper end of the scraper 1 is used to abut against the pressure roller 12. The upper end of the vibrating plate 2 is hinged to the bottom of the scraper 1 so that the scraped material on the scraper 1 can fall onto the vibrating plate 2. Both the vibrating plate 2 and the pressure roller 12 are inclined downwards. The lower end of the vibrating plate 2 is located in the collection trough 3 so that the scraped material can fall into the collection trough 3. The collection trough 3 is provided with an L-shaped mounting bracket 4 and a mounting plate 7 is also provided on one side. The driven roller 6 is rotatably mounted on the mounting plate 7. The roller shaft end of the driven roller 6 is also provided with a connecting plate 8. An eccentric shaft 9 is provided on the connecting plate 8. A connecting rod 10 is hinged on the eccentric shaft 9. The end of the connecting rod 10 is hinged to the bottom of the vibrating plate 2. The driven roller 6 is used to abut against the pressure roller 12.

[0020] like Figure 4 As shown, this utility model also provides a road compaction device, including the aforementioned roller cleaning mechanism, a support frame 11, and a roller 12. The roller 12 is disposed within the support frame 11, and the roller cleaning mechanism is mounted on the support frame 11. The scraper 1 and driven roller 6 of the roller cleaning mechanism both abut against the roller 12. A fixing bolt 13 is screwed onto the support frame 11, and the fixing bolt 13 passes through the slotted hole 5 of the roller cleaning mechanism to facilitate adjustment of the distance between the roller cleaning mechanism and the roller 12.

[0021] The working principle of this utility model is as follows:

[0022] During operation, the pressure roller 12 moves along... Figure 4 When the roller 12 rotates in the indicated direction, the foreign objects adhering to it are scraped off by the scraper 1 and fall onto the vibrating plate 2. The driven roller 6 is synchronously driven to rotate by the roller 12, which in turn causes the connecting plate 8 and the eccentric shaft 9 to rotate around the roller shaft of the driven roller 6. The connecting rod 10 drives the vibrating plate 2 to swing up and down, shaking the foreign objects into the collection tank 3.
