Description

Mud scraping plate device of road roller Technical Field The utility model belongs to the technical field of engineering machinery, and particularly relates to a mud scraping plate device of a road roller. Background In road construction, the road roller is used as key equipment, the effect of the road roller is important, the road roller compacts pavement materials through gravity and mechanical vibration to ensure structural strength and flatness, however, the compression roller is easy to adhere sundries when contacting with viscous materials (such as soil and asphalt), so that the surface of the compression roller is uneven, the compacting effect is affected, and the pavement quality defect is caused. However, the existing mud scraping plate is mostly arranged obliquely downwards towards the compression roller of the road roller, the scraped sundries are easily accumulated above the mud scraping plate due to the structure, as the accumulation amount is increased, extra friction is generated between the sundries above the mud scraping plate and the compression roller, abrasion of the surface of the compression roller is increased, damage of the mud scraping plate can be accelerated, the service lives of the two are greatly shortened, meanwhile, the sundries accumulated above the mud scraping plate can fall to the ground from two ends of the mud scraping plate, particularly when the sundries fall to the ground area which is already compacted, bulges or pits are formed on the ground, the quality and flatness of the compacted area are seriously affected, in addition, the mud scraping plate is worn to a certain extent after being used for a period of time, so that gaps between the mud scraping plate and the compression roller are enlarged, the mud scraping effect of the mud scraping plate is directly weakened, the sundries on the surface of the compression roller are difficult to be thoroughly removed, the gaps are required to be frequently adjusted manually, and the construction efficiency is greatly reduced, and the construction cost is increased.
