Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a road roller scraper which is easy to disassemble. Background Art

[0002] A road roller, also known as a soil roller, is a piece of road construction equipment. Among construction machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-sticky and sticky soils, roadbed stabilized soil, and asphalt concrete pavement layers. Road rollers use the gravity of the machine itself and are suitable for various compaction operations, causing the compacted layer to undergo permanent deformation and become dense. Road rollers are divided into two types: steel wheel type and tire type. A sprinkler tank is usually installed on the steel wheel of the road roller, and the existing sprinkler tanks still have certain defects when used. The road roller is provided with a scraper on its steel wheel for scraping off the mud on its surface. However, the scraper is installed on the outside of the steel wheel by fixing bolts. As the use time increases, the scraper is prone to deformation and the scraping effect becomes worse. The installation of the fixing bolts leads to slow efficiency in removing and replacing the scraper, and tools are required, which is troublesome to operate. In addition, some materials adhered to the surface of the steel wheel have a large adhesion area and are firmly adhered. The scraper is more laborious when scraping, and the scraper and the steel wheel always maintain the same distance, which is not conducive to actual engineering application. Utility Model Content

Three sets of sleeves 39 are movably arranged on the inner side of the scraper body 38, butterfly nuts 310 are movably sleeved on the outer sides of the three sets of sleeves 39, movable rods 311 are movably arranged on the inner sides of the three sets of sleeves 39, and circular rings 312 are fixedly arranged on the rear sides of the three sets of movable rods 311. Movable grooves 313 are opened on the inner sides of the three sets of sleeves 39 at positions corresponding to the three sets of circular rings 312, and circular blocks 314 are fixedly arranged on the rear ends of the three sets of circular rings 312. Circular grooves 315 are opened on the rear sides of the three sets of sleeves 39 at positions corresponding to the three sets of circular blocks 314. Reset springs 316 are fixedly connected between the three sets of circular rings 312 and the circular grooves 315. Four sets of spring blocks 317 are movably arranged on the outer sides of the three sets of movable rods 311, and openings 318 are opened on the interiors of the three sets of sleeves 39 at positions corresponding to the three sets of spring blocks 317.

[0021] In this embodiment, the shape of the roller body 1 and the connecting rod 36 is U-shaped, the screw rod 33 and the support rod 31 are movably connected, the mounting rod 35 and the screw rod 33 are threadedly connected, the mounting rod 35 and the scraper body 38 are inclined, several groups of blades 37 are linearly and evenly arranged, several groups of blades 37 are in contact with the outer wall of the steel wheel body 2, the butterfly nut 310 and the sleeve 39 are threadedly connected, the movable rod 311, the ring 312, and the round block 314 are arranged as an integrated structure, the ring 312 is limited to move on the inner side of the movable groove 313, the round block 314 is limited to slide on the inner side of the circular groove 315, and the spring block 317 is adapted to the opening 318.

[0022] Specifically, firstly, the screw rod 33 is driven to rotate by starting the motor 32, so that the threaded mounting rod 35 slides up and down on the outside of the sliding rod 34, and the distance between the steel wheel body 2 is adjusted in real time to meet the engineering requirements and improve practicality. The material with a large adhesion area on the outside of the steel wheel body 2 is cut by the connecting rod 36 and several groups of blades 37, so as to facilitate the scraping of the scraper body 38 to avoid residue, reduce the burden of the scraper body 38, and thus increase its service life. In addition, by pressing the movable rod 311 backward, the ring 312 moves backward on the inner side of the movable groove 313, compressing the reset spring 316, so that the round block 314 enters the rear side of the circular groove 315, and the movable rod 311 drives the four groups of movable connecting spring blocks 317 to move backward. The movable groove 313 is inserted into the interior of the four groups of spring blocks 317, thereby making the four groups of spring blocks 317 fit with the movable rod 311.

According to the elastic action of the reset spring 316, the round block 314, the ring 312, and the movable rod 311 are reset, so that the four groups of spring blocks 317 leave the restriction of the movable groove 313, and pop out from the inner side of the four groups of openings 318 to press against the rear end of the mounting rod 35. By rotating the butterfly nut 310 backward on the outer side of the sleeve 39 until it fits with the front end of the scraper blade body 38, the mounting rod 35 and the scraper blade body 38 are fixedly installed. The operation is simple, thereby improving the work efficiency of disassembling and replacing the scraper blade body 38, and no tools are required to assist, saving time and effort.

[0023] Working principle:

[0024] When in use, first start the motor 32 to drive the screw 33 to rotate, so that the threaded installation rod 35 slides up and down on the outside of the sliding rod 34, and the distance between the steel wheel body 2 is adjusted in real time to meet the engineering requirements and improve practicality. The material with a large adhesion area on the outside of the steel wheel body 2 is cut through the connecting rod 36 and several groups of blades 37, so that it is convenient for the scraper body 38 to scrape and avoid residue, reduce the burden of the scraper body 38, and thus increase its service life. In addition, by pressing the movable rod 311 backward, the ring 312 moves backward on the inner side of the movable groove 313, compressing the reset spring 316, so that the round block 314 enters the rear side of the circular groove 315, and the movable rod 311 drives the four groups of movable connecting spring blocks 317 to move backward. The movable groove 313 is inserted into the interior of the four groups of spring blocks 317, thereby making the four groups of spring blocks 317 fit with the movable rod 311. At this time, the sleeve 39 is inserted into the inner side of the scraper blade body 38 and the mounting rod 35, and the movable rod 311 is loosened. According to the elastic action of the reset spring 316, the round block 314, the ring 312, and the movable rod 311 are reset, so that the four groups of spring blocks 317 leave the restriction of the movable groove 313, and pop out from the inner side of the four groups of openings 318 to press against the rear end of the mounting rod 35. By rotating the butterfly nut 310 backward on the outer side of the sleeve 39 until it fits with the front end of the scraper blade body 38, the mounting rod 35 and the scraper blade body 38 are fixedly installed. The operation is simple, thereby improving the work efficiency of disassembling and replacing the scraper blade body 38, and no tools are required to assist, saving time and effort.
