Description

Technical Field

[0001] This utility model belongs to the field of road construction machinery technology, and in particular relates to a scraper structure for a trailer roller. Background Technology

[0002] A towed vibratory roller is a cylindrical roller that is towed by a power tractor. The roller uses its own weight to statically compact the ground. An engine is installed on the rear-towed roller, which adds an eccentric rotating device to the cylinder. The centrifugal force generated by the rotation of the eccentric block causes the roller to vibrate, thereby achieving vibratory compaction.

[0003] During the road rolling process, the roller will stick to mud, sand and other debris. When compacting different types of soil or facing different construction site conditions, the angle of the scraper needs to be adjusted to better adapt to different construction conditions. Therefore, a scraper structure for trailer rollers is needed, in which the angle of the scraper is adjusted by a cylinder, so that the scraper can scrape off the debris, effectively preventing the debris from accumulating on the surface of the roller and adapting to different working conditions. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A scraper structure for a trailer roller includes a connecting frame rotatably connected to the surface of the roller. Two symmetrical L-shaped plates are fixedly connected to the top of the connecting frame. A fixing plate is welded to the surface of the two L-shaped plates. A limit rod is fixedly connected between the two L-shaped plates. Two symmetrical connecting blocks are rotatably connected to the surface of the limit rod. A connecting plate is fixedly connected to the top of the two connecting blocks. A scraper is provided on the inner wall of the connecting plate. A U-shaped block is fixedly connected to the top of the fixing plate. A cylinder is provided on the inner wall of the U-shaped block. A U-shaped block is fixedly connected to the bottom of the connecting plate. A bolt rod is installed between the connecting plate and the scraper. A nut block is threaded onto the surface of the bolt rod.

[0006] Preferably, the surface of the scraper blade is provided with an inclined surface.

[0007] Preferably, the inner wall of the U-shaped block is rotatably connected to the surface of the cylinder.

[0008] Preferably, the output end of the cylinder is rotatably connected to the inner wall of the second U-shaped block.

[0009] Preferably, an elastic washer is fitted onto the surface of the bolt rod.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a cylinder to drive the connecting plate to rotate. With the cooperation of the limiting rod and the connecting block, the connecting plate drives the scraper to adjust the angle, so that the scraper can scrape off the debris, effectively preventing the debris from accumulating on the surface of the roller, and can adapt to different working conditions.

[0012] 2. The inclined surface of this utility model makes it easier for the mud scraper to scrape up the mud when scraping.

[0013] 3. By using an elastic washer, this utility model increases the friction on the surface of the bolt rod, thus preventing the bolt rod from loosening and coming off due to external vibration. Attached Figure Description
