摘要： A fore-and-aft extending transport hitch frame carried on a pair of ground wheels supports the innermost ends of a pair of end wheel wing drills and tows a trailing end wheel drill between the wing drills. The wing drills are connected to rearwardly angled upright pivot structures on the hitch frame by hinged bracket structure which causes the innermost ends of the wing drills to lift as the drills are pivoted forwardly toward a transport position. The forward end of the hitch frame is lifted to raise the outboard ends of the wing drills for transport. During planting operations the ground wheels effectively act as the inboard end wheels for the wing drills. The wing drills can rock vertically about the bracket structure hinge for good flexibility in the field-working position.
摘要翻译： 在一对地面轮上承载的前后延伸的运输搭接架支撑一对端轮翼钻的最内端，并且在机翼钻头之间拖动后端轮钻。 机翼钻头通过铰接支架结构连接到搭接架上的向后倾斜的直立枢轴结构，当支架朝向输送位置向前枢转时，使得机翼钻头的最内端部提升。 悬挂架的前端被提起以升高机翼钻机的外侧端部以便运输。 在种植操作期间，地面轮有效地用作机翼钻机的内侧端轮。 机翼钻头可以围绕支架结构铰链垂直摇摆，在现场工作位置具有良好的灵活性。

摘要： Agricultural hopper structure for containing two different granular materials such as seed and fertilizer. Two molded plastic containers are nested together and supported on a frame. The nested ends of the containers are concave and convex, respectively, to provide a symmetrical appearance while establishing unequal container capacity. The nested containers include a downwardly directed ledge structure freely resting on a corresponding upwardly facing load-bearing surface of the frame to reduce the number of fixed attaching points. The upper portions of the containers extend above the frame and have outwardly convex sidewalls. The hopper structure is fabricated by first nesting the containers and then lowering the nested containers onto the frame.
摘要翻译： 农用料斗结构，含有两种不同的颗粒物料，如种子和肥料。 两个模塑塑料容器嵌套在一起并支撑在框架上。 容器的嵌套端分别是凹的和凸的，以提供对称的外观，同时建立不相等的容器容量。 嵌套的容器包括向下指向的凸缘结构，其自由地搁置在框架的相应的向上的承载表面上，以减少固定的附接点的数量。 容器的上部在框架的上方延伸并具有向外凸出的侧壁。 料斗结构通过首先将容器嵌套，然后将嵌套的容器降低到框架上来制造。

摘要： A grinder-mixer having a trough-shaped mixing tank, a horizontal transfer and mixing auger seated along the bottom of the tank and extending into the hammer mill, and a vertical auger in the tank for elevating the material for recirculation or discharge. Mixing capacity is increased with the larger tank and bridging of material is minimized with steeply inclined tank walls, a centrally mounted agitator and the trough-mounted mixing auger. Power train demands are reduced through utilizing only two auger conveyors to transfer material from the hammer mill, mix it in the tank and elevate it for recirculation or discharge. Improved intermixing is provided through stepped pitch flights provided on the horizontal mixing auger.
摘要翻译： 具有槽形混合槽的研磨机混合器，沿着罐底部放置并延伸到锤磨机中的水平传送和混合螺旋推运器，以及用于提升用于再循环或排出的材料的立式螺旋推运器。 混合容量随着较大的罐而增加，并且材料的桥接被最小化，具有倾斜倾斜的箱壁，中心安装的搅拌器和槽安装的混合螺旋钻。 通过仅使用两个螺旋输送机从锤磨机中转移材料，将其混合在罐中并将其提升以用于再循环或排出，从而减少动力传动系的需求。 通过在水平搅拌螺旋推运器上提供的台阶间距提供改进的混合。

摘要： A single disk opener blade is supported for rotation about a horizontal axis offset approximately seven degrees from the transverse direction. A seed tube extends closely adjacent the disk blade forwardly of the rotational axis generally in the shadow of the leading edge of the blade. The tube is angled around the disk blade hub to provide a narrow profile and to reduce the vertical velocity of the material deposited in the furrow. A furrow-firming and blade-scraping extension is connected to the lower end of the tube and extends rearwardly to a location behind the axis. The side of the firming extension is located transversely beyond the shadow of the disk blade to help form one side of the seed trench and to permit the seed to settle in the trench. Depth control structure includes a wheel support arm fixed to one end of the disk blade spindle and a quadrant fixed to the opposite end of the spindle for selectively adjusting the arm. A depth control wheel is mounted on the arm about an axis offset from the axis of the disk blade for rotation against the leading side of the blade to clean the blade, hold down trash and dirt, and provide positive depth control.
摘要翻译： 支撑单个盘开启器叶片围绕横向偏移大约七度的水平轴线旋转。 种子管通常在叶片的前缘的阴影中沿旋转轴线向前靠近盘片叶片延伸。 管围绕盘片轮毂成角度以提供窄的轮廓并且减小沉积在沟槽中的材料的垂直速度。 沟槽紧固和刮刀刮除延伸部连接到管的下端并向后延伸到轴后方的位置。 紧固延伸部的侧面横向超过盘片的阴影，以帮助形成种子沟槽的一侧并允许种子沉淀在沟槽中。 深度控制结构包括固定到盘片主轴的一端的轮支撑臂和固定到主轴的相对端的象限，用于选择性地调节臂。 深度控制轮围绕从盘片的轴线偏移的轴线安装在臂上，用于相对于叶片的前侧旋转以清洁刀片，按压垃圾和污物，并提供正的深度控制。

摘要： A two-wheeled trailer hitch supporting two three-point hitch mounted implements side-by-side for field operation. The implements are mounted on outriggers which are foldable forwardly to narrow the unit for transport. A pair of rigid diagonal drag links movable fore-and-aft by a cylinder-activated slide block is connected to the outriggers for pivoting them approximately ninety degrees between the field and transport positions. Lift frame structures selectively engage the three-point hitch linkages to raise the implements on the respective outriggers. The lift frame structure is disengaged from the linkages when the implements are lowered for greater flexibility in the field-working position.
