Description

Technical Field

[0001] The present invention belongs to the field of road rollers, and particularly relates to a scraper assembly for cleaning the roller of a road roller. Background Art

[0002] A road roller is a construction machine that uses its own gravity to compact the roadbed or road surface, and is widely used in infrastructure construction fields such as highways, railways, and airports. During the working process of the road roller, materials such as soil and asphalt will adhere to the surface of the roller, affecting the compaction effect and road surface quality. Therefore, it is necessary to regularly clean the surface of the roller.

[0003] Currently, the common method for cleaning the roller is to install a scraper on the outer side of the roller, and use the relative movement between the scraper and the roller surface to scrape off the materials adhering to the roller surface. However, the existing scraper structure has the following deficiencies: the scraper is always in contact with the roller surface, and needs to bear a large frictional force and impact force for a long time, which is easy to wear and damage, affecting the use effect. The existing scraper is fixedly installed on the roller frame and cannot be replaced separately. Summary of the Invention

[0050] Now, a specific introduction is provided for the scraper 05 assembly for cleaning the roller 06 of the road roller provided in the present application:

[0051] As shown in the Figures 1-6 drawing, the scraper 05 assembly for cleaning the roller 06 of the road roller includes a mounting frame 02, a pair of clamping members 08, a transmission member 04, and a scraper 05. The mounting frame 02 is used to connect the frame 03 of the roller 06. The clamping members 08 are respectively connected to the mounting frame 02 and can slide along the length direction of the mounting frame 02. Both ends of the transmission member 04 are respectively connected to the two clamping members 08 and are used to drive the two clamping members 08 to slide towards or away from each other. The scraper 05 can be fixedly clamped between the two clamping members 08. In the use state, the scraper 05 is inclined in front of the advancing direction of the roller 06 and the top of the scraper 05 is in frictional connection with the roller 06. The sundries on the roller 06 are scraped off through the relative movement between the scraper 05 and the roller 06. Among them, the two clamping members 08 are used to clamp both ends of the scraper 05. When disassembling the scraper 05, the transmission member 04 drives the two clamping members 08 to move away from each other, and the staff can take out the scraper 05 from the clamping members 08 for replacement. When installing the scraper 05, place the scraper 05 between the clamping members 08, and the transmission member 04 drives the two clamping members 08 to move towards each other until the scraper 05 is firmly clamped in the middle of the clamping members 08.

[0052] In the embodiment of the present application, the scraper 05 is detachably mounted on the mounting frame 02 through the clamping members 08. When the scraper 05 is worn or damaged, it can be replaced at any time to ensure the cleaning effect of the scraper 05 assembly.

[0053] In a specific embodiment, as shown in the Figures 1-3As shown, the scraper 05 cleaning assembly for the roller of the road roller further includes a connecting member 01. The connecting member 01 is connected between the mounting frame 02 and the frame 03 of the roller 06, enabling the mounting frame 02 to flip in the traveling direction of the road roller. The flipping angle of the mounting frame 02 is less than 45°, and the mounting frame 02 is flush with the frame 03 of the roller 06 in front of the roller 06 in the unused state. When cleaning is required, the drive motor 012 drives the mounting frame 02 to flip towards the roller 06 through the second connecting plate until the top of the scraper 05 contacts the roller 06.

[0054] In the embodiment of the present application, the mounting frame 02 is rotatably mounted on the frame 03 of the roller 06 through the connecting member 01. When the roller 06 does not need to be cleaned, the scraper 05 can be flipped away from the roller 06, and the scraper 05 does not need to continuously bear the frictional force and impact force of the roller 06, reducing the damage probability of the scraper 05 and improving the service life of the scraper 05.
