Road roller mud scraping device capable of realizing extending and retracting of mud scraping plates through centrifugal force

Abstract

The invention discloses a road roller mud scraping device capable of realizing extending and retracting of mud scraping plates through centrifugal force. The road roller mud scraping device structurally comprises an efficient energy-saving motor, a supporting frame, a driving wheel, a transmission belt, a mud scraping device body and road roller steel wheels, the supporting frame is mechanically connected to a road roller, and the efficient energy-saving motor is mounted on the bottom face in the supporting frame. Compared with the prior art, the road roller mud scraping device has the beneficial effects that during rotating, mud scraping mechanisms can throw concrete away through the centrifugal force and do not intervene in one other, the situation that the concrete is thrown on the mudscraping mechanisms on the rear part can be avoided, through the centrifugal force, the mud scarping plates can have the automatic extending and retracting functions, the situation that gaps between the mud scraping plates and the steel wheels are adjusted manually even if the mud scraping plates are abraded is avoided, the mud scraping plates can always be attached to the steel wheels, thus the mud scraping plates are always in the mud removing work state in the compaction operation, the flatness of a pavement compacted by the steel wheels is improved advantageously, in addition, the mud scraping plates are convenient to mount and demount and do not need to be replaced integrally, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a mud scraping device for a road roller that realizes the expansion and contraction of the mud scraper through centrifugal force. Background technique [0002] Road rollers are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. On the surface of the steel wheel, the steel wheel roller generally has a mud scraping device, which is convenient for scraping the steel wheel. In order to protect the steel wheel from being worn out in the scraped mud, the mud scraper is generally made of nylon. Over time, the scraper will be worn and thinned due to long-term scraping of mud, so that the distance between the scraper and the steel wheel will become larger, so it is necessary to adjust the distance between the scraper and the steel wheel to facilitate scraping.

Problems solved by technology

[0004] The inventors found that the device is manually adjusted for the distance between the scraper and the steel wheel, and it is necessary to manually observe the gap between the scraper and the steel wheel. The gap between the steel wheels is too large and the concrete cannot be touched, resulting in more concrete and other adhesives attached to the steel wheels. When the asphalt concrete road is compacted, the road surface will be uneven and potholes.
