Land leveler for roadbed and pavement construction

Abstract

The invention relates to the technical field of land levelers, and discloses a land leveler for roadbed and pavement construction, the land leveler comprises a machine body and a scraper, the scraper is internally provided with a movable cavity, the bottom surface of the movable cavity is slidably sleeved with a movable rod, and the outer surface of the movable rod and the interior of the movable cavity are fixedly sleeved with a stop block; a spring is fixedly connected to the bottom face of the movable cavity and located on the outer side of the movable rod, a pressing plate is fixedly connected to the bottom of the movable rod, a sliding groove is formed in the position, located on the left side of the movable cavity, in the scraper, a telescopic rod is slidably connected into the sliding groove in a sleeved mode, and a tension spring is fixedly connected to the position, located on the outer side of the telescopic rod, in the sliding groove. According to the device, the scraper is continuously jacked to the telescopic rod on the surface through soil, so that the telescopic rod continuously reciprocates in the sliding groove to jack the movable rod and the pressing plate to move upwards, then potential energy of the spring and the gravity of the pressing plate are used for descending, the pressing plate is used for leveling the soil crossing the scraper, and the flatness of the soil is ensured.

Description

technical field [0001] The invention relates to the technical field of graders, in particular to a grader used for roadbed and road construction. Background technique [0002] Motor graders are the main machinery used for shaping and leveling operations in earthworks. They are widely used in road subgrade construction and some large-area ground construction to ensure the smoothness of subgrades, so that the pressure on the road after completion can be evenly distributed. Thereby increasing the service life of the road. [0003] In the process of using the existing leveling machine, the ground is often loosened by the scarifier in front of the machine, and then the ground after being loosened is smoothed by the scraper on the rear side of the scarifier, so as to achieve the leveling effect of the ground. However, when the scraper is constantly moving and scraping the soil, the soil it scrapes will continue to move along the blade surface of the scraper. During long-term oper...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing grader proposed in the background technology, the present invention provides a grader for roadbed and road surface construction, which can effectively level the soil passing over the scraper and clean the sticky soil. The advantage of the soil on the blade face of the scraper solves the technical problems raised in the background art above
