The laser grader is mainly composed of a laser emitter, a laser receiver, a controller, a hydraulic system and a level shovel, and the leveling precision of the land is up to 2 cm.
The working principle is as follows: the laser emitter emits a reference circular plane of a certain diameter (the reference slope can also be provided). The receiver mounted on the blade support rod controls the hydraulic actuator by processing the collected signal through the controller. The hydraulic mechanism can control the up and down movement of the scraper shovel as required , and the land leveling operation can be completed.
