    • A ditching apparatus features front blade sections fixed to the frame in a V-configuration, and a pull tongue extending over the blade apex to a pivotal connection near a rear of the frame. An actuation mechanism effects relative pivoting between the frame and the pull tongue to adjust an angle between the front blade and the trailer tongue to control a ground-penetration depth of the blade apex. Two rear blade sections on opposing sides of the frame are movable between deployed positions extending rearwardly and laterally outward from the front blade sections, and stowed positions elevated out of the deployed positions. The blade angle and width are thus controllable to achieve a desired depth and width of ditch. A nose cap at the blade apex provides an improved ground breaking action, while internally braced blade structures will roll formed skins provide durability and smooth rolling action of displaced earth.
    • 脱水装置具有以V形结构固定到框架的前叶片部分,以及在叶片顶部延伸到靠近框架后部的枢转连接的拉舌。 致动机构实现框架和拉舌之间的相对枢转以调节前叶片和拖车舌之间的角度,以控制叶片顶点的地面穿透深度。 在框架的相对侧上的两个后叶片部分可在从前叶片部分向后延伸和横向向外延伸的展开位置之间移动,并且从展开位置升高的收起位置可移动。 因此,叶片的角度和宽度是可控制的,以实现所需的沟槽深度和宽度。 叶片顶端的鼻盖提供了改进的开裂作用,而内部支撑的叶片结构将成形成皮肤,提供了移动地球的耐久性和平滑的滚动动作。
