The application relates to a method for improving the surface quality of 20CrNiMo forgings, which can effectively improve the surface color difference problem of the 20CrNiMo forgings and improve the product quality. Through high-temperature heating, the composition homogenization is effectively promoted, and the composition segregation phenomenon is reduced. The two roughing + thinning methods and the interchanging of the thickness and width dimensions of the forging are adopted to effectively ensure the compaction effect of the forgings, sufficiently break the coarse organization of the steel ingot, and break the internal dendritic segregation of the steel ingot in the one roughing + thinning deformation + high-temperature homogenization + two roughing + thinning deformation mode for the first time, shorten the diffusion distance between the dendrites, and further promote the organization and composition homogenization, so that the surface color difference quality problem of the forgings is effectively improved. Through the heat treatment after forging, the forging organization is not only refined, but also the internal stress of the forging is removed, so that the mechanical property result reaches the standard requirement.

This invention relates to the field of road construction and discloses a slope trimming device for high-fill embankments. The device includes a transport vehicle, a crane, and a slope trimming unit. The crane is mounted on the transport vehicle, and the slope trimming unit is connected to the crane. The slope trimming unit includes a portal frame with traveling wheels on both sides for movement on the slope. A trimming mechanism is installed inside the traveling frame, and a rotatable support shaft is mounted on the top of the traveling frame. Three sets of cable rollers and one electric wire roller are sequentially mounted on the support shaft, and a motor is mounted on the traveling frame. This invention, by mounting a crane on a transport vehicle, allows the slope trimming unit to easily trim the slopes of high-fill embankments. Furthermore, the traveling frame, trimming mechanism, support shaft, cable rollers, and motor eliminate the need for manual operation on the slope, significantly improving slope trimming efficiency and ensuring worker safety.

A self-cleaning land compaction device, relating to the field of compaction equipment technology, includes a main frame, a front compaction roller assembly mounted on the main frame, and a first scraping assembly mounted on the front compaction roller assembly. During the movement of the front compaction roller assembly, its first compaction surface compacts the land. When the soil moisture is high, soil adheres to the first compaction surface. The first scraping side of the first scraping assembly blocks the soil on the first compaction surface and scrapes it off. Furthermore, the first scraping side can be adjusted to always adhere to the first compaction surface to ensure optimal scraping effect. During the compaction process of the front compaction roller assembly, the adhering soil is continuously scraped off by the first scraping assembly, ensuring the flatness of the first compaction surface and thus guaranteeing the subsequent land compaction effect.
