Background

The grader is an earthmoving machine for leveling the ground by using a scraper, and is a main machine for shaping and leveling operations in earthmoving works. Bulldozers are the main configuration tools of graders, and are mainly used for soil scraping, rough leveling, stacking and other operations. However, due to the complexity of the road surface and the interior of the soil, such as in areas like mountains, there is often a large number of stones which tend to damage the bulldozer during operation.

The patent with the application number of CN202022193920.3 provides a road construction land leveler, which comprises a land leveler body, a main frame, a bulldozer and a land leveler, wherein the main frame is fixedly connected to the front end of the body, the bulldozer is rotatably connected to the tail end of the main frame, which is far away from the body, through a second connecting rod, and the land leveler is rotatably connected below the main frame through a turntable; the bulldozing device comprises a push plate, a rotating shaft and a baffle plate, wherein the rotating shaft is rotatably connected to the upper end of the push plate along the length direction of the push plate, the baffle plate is arranged on the rotating shaft of one side end face of the push plate, and the baffle plate can move along the axial direction of the rotating shaft.

Although this technique prevents the land leveler from being damaged to a certain extent, the switching between the bulldozer and the land leveler affects the efficiency of the grader, and if the bulldozer only pushes away stones visible in advance, prevention cannot be performed which cannot be seen under the soil, and there are certain limitations.
