Adjustable road roller mud-scraping board based on spring force increasing principle

Abstract

The invention relates to the technical field of road construction equipment and discloses an adjustable road roller mud-scraping board based on spring force increasing principle. The adjustable road roller mud-scraping board based on the spring force increasing principle comprises a pressing wheel; the outer part of the pressing wheel is fixedly connected with a front supporting frame, a back supporting frame, a left supporting frame and a right supporting frame; the internal parts of the front supporting frame and the back supporting frame are movably connected with a front fixed rod and a back fixed rod correspondingly; the outer parts of the front fixed rod and the back fixed rod are fixedly connected with pressure assemblies correspondingly; the outer parts of the pressure assemblies are fixedly connected with connecting rods; mud-scraping boards are fixed on the outer parts of the connecting rods correspondingly; through cooperative use of the pressure assemblies and the mud-scraping boards, the pressure on the mud-scraping boards by the pressure assemblies is proper when the mud-scraping plates are contacted with the pressing wheel, so frictional loss to the mud-scraping boards by the pressing wheel is reduced; and in the road pressing process, the pressure is doubled if the mud-scraping plates move backwards, so that the mud-scraping effect is guaranteed and the road pressing quality of the road roller is guaranteed.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to an adjustable road roller scraper based on the principle of spring force increase. Background technique [0002] At present, the country is vigorously developing infrastructure construction, and road paving is a very important part of it. When laying roads, various equipment is required. In road paving, compaction of the road surface is a crucial step. Whether the road is compacted It is a key factor for the quality of road paving and the length of time of use. The road roller is the main equipment for road compaction. It can roll sandy, semi-cohesive and cohesive soils, roadbed stabilized soils and asphalt concrete pavement layers. [0003] When the road roller is rolling the road, there will usually be soil and other debris attached to the roller, which will cause uneven soil layer after rolling and affect the road quality of the roller. Therefore, a mud scr...

Problems solved by technology

[0003] When the road roller is rolling the road surface, there are usually dirt and other sundries attached to the rollers, resulting in uneven soil layer after rolling, which affects the quality of the road roller. Therefore, a mud scraper is usually installed to scrape off the attached soil , while the existing mud scrapers are usually installed fixedly. When the gap is too small, it is often easily damaged due to excessive friction. When the gap is too large, it cannot meet the scraping of some small stickies. Both will cause friction on the front and rear mud scrapers, increasing unnecessary loss
