The invention discloses a grader scraper knife control mechanism which comprises a scraper knife body and a blade part, the scraper knife body comprises a cross beam, rib plates and a panel, the multiple rib plates are arranged in parallel and fixed to the lower surface of the cross beam, the panel is fixedly connected with the cross beam and the rib plates, and the blade part comprises a plurality of fixed blade teeth and movable blade teeth. The fixed blade teeth and the movable blade teeth are arranged alternately and linearly, the fixed blade teeth are fixedly installed at the bottom ends of the rib plates, adjusting assemblies are arranged on the back face of the scraper knife body, the movable blade teeth are driven by the adjusting assemblies to move up and down, and the adjusting assemblies are arranged in gaps between the adjacent rib plates. According to the mechanism, in the bulldozing and leveling process of the scraper knife, the blade teeth are driven to vibrate and swing in a reciprocating mode, block stones are kicked out, turned soil is more relaxed, friction force of the turned soil is reduced, soil can move to one side more smoothly along the surface of the panel, the effect of reducing soil resistance is achieved, the load of the scraper knife is relieved, and the earth leveler is more oil-saving under the normal working condition.
本发明公开了一种平地机铲刀控制机构，包括铲刀主体和刃部，所述铲刀主体包括横梁、筋板和面板，多个筋板平行设置并固定在横梁的下表面，面板与横梁和筋板固定连接，所述刃部包括若干个固定刃齿和活动刃齿，固定刃齿和活动刃齿相间设置，并呈直线排列，所述固定刃齿固定安装在筋板的底端，铲刀主体背面设置有调节组件，通过调节组件驱动活动刃齿可上下移动，相邻筋板之间的间隙处设置有调节组件。本机构在铲刀推土、平土过程中，驱动刃齿振动和往复摆动，踢出块石，并使翻土更加松弛，降低其摩擦力，使土料能够更加流畅的沿面板表面移至一侧，达到降低土料阻力的效果，减轻铲刀的负载，使平土机正常工况更加省油。
