Abstract
A grader and slope scraping control method and device include a grader having a front frame; a blade mounted on the front frame, an attitude of the blade is adjustable; an actuator for adjusting the attitude of the blade; a first angle detecting member for detecting a first inclination angle in a front and rear direction of the grader relative to a horizontal plane and a second inclination angle in a left and right direction relative to a horizontal plane; a blade detecting member for detecting attitude information of the blade relative to the front frame; and a controller, for obtaining an actual slope angle based on the first inclination angle, second inclination angle and attitude information, and make the actuator adjust attitude of the blade to a target slope angle when the actual slope angle is inconsistent with the preset target slope angle.
