    • A guidance control system for a harvester or like machinery includes a steering linkage operatively connected to at least one ground engaging wheel. Harvester steering is controlled through the linkage by either an operator controlled steering wheel or a sensor responsive self-steering mechanism. The sensor responsive self-steering mechanism includes a guide assembly pivotally mounted to the harvester. The guide assembly includes a pair of laterally spaced, cooperating tines that define a path therebetween for plants being harvested. A sensor positioned on each tine senses the position of plants as they are harvested. A control circuit is responsive to the sensors to selectively impart movement to the steering linkage to self-steer the harvester. The control circuit includes a main valve controlled by the operator controlled steering wheel and a secondary valve controlled by the sensors. An auxiliary feed line leads from the main valve to the secondary valve. When the operator utilizes the steering wheel control, an interrupter blocks hydraulic flow through the auxiliary line from the main valve to the secondary valve. Thus, operator controlled steering input overrides the sensor responsive self-steering for maximum safety. The guidance control system also eliminates harvester wander back and forth across a row by substantially preventing overcompensation by the sensor responsive self-steering.
    • 用于收割机或类似机械的引导控制系统包括可操作地连接到至少一个接地轮的转向连杆。 收割机转向通过操作者控制的方向盘或传感器响应的自动转向机构的联动来控制。 传感器响应自转机构包括枢转地安装到收割机的引导组件。 引导组件包括一对侧向间隔开的协作齿,其间限定了用于收获的植物的路径。 定位在每个齿上的传感器在收获植物时检测植物的位置。 控制电路响应于传感器选择性地向转向连杆机构施加运动以自动转向收割机。 控制电路包括由操作者控制的方向盘控制的主阀和由传感器控制的次级阀。 辅助进料管线从主阀通向二次阀。 当操作者利用方向盘控制时,断路器阻挡从主阀到辅助阀的辅助管路的液压流。 因此,操作员控制的转向输入覆盖传感器响应式自动转向,以获得最大的安全性。 引导控制系统还通过基本上防止传感器响应自动转向的过度补偿而消除收割机来回移动。

    • A mechanism for harvesting tobacco plants includes a magazine of rails. Each rail is elongated and hollow, with a slot along a bottom portion of each rail. Two opposing dispensing conveyors each engage opposing ends of each rails for advancing an empty rail to a filling position. Two opposing notching conveyors grasps the plants and cuts notches into the plants on opposing sides of the plant. A single roller chain stepping conveyor moves the plants from the opposing notching conveyors into a rail in the filling position. The two opposing dispensing conveyors advance the rail filled with plants. An unloading conveyor having opposing roller chains receives the rails filled with plants, collects a group of filled rails, and unloads the group of filled rails on a ground level at a linear speed equal to a forward speed of the harvesting mechanism.
    • 用于收获烟草植物的机构包括一个栏杆。 每个轨道是细长的和中空的,沿着每个轨道的底部具有槽。 两个相对的分配输送机各自接合每个轨道的相对端部,以将空的轨道推进到填充位置。 两个相对的凹口传送带抓住植物并将植物的相对侧的切口切入植物。 单个滚子链式步进输送机将植物从相对的切口输送机移动到填充位置的轨道中。 两个相对的分配输送机推进充满植物的轨道。 具有相对的滚子链的卸载输送机容纳填充有工厂的轨道,收集一组填充的导轨,并且以等于收获机构的前进速度的线速度在地平面上卸载一组填充的导轨。

    • According to an embodiment of the invention, a method of dynamically creating a network of a plurality of nodes operable to communicate with objects in operating sectors comprises establishing a first communication link between a first node and a second node of the plurality of nodes. The first communication link is established upon determining that the first communication link between the respective ones of the plurality of nodes would not cross an existing communication link in the network of the plurality of nodes between two of the plurality of nodes or upon determining that the first communication link would be shorter than any existing communication link in the network of the nodes between two of the plurality of nodes that the first communication link would cross. The first communication link has a first communicative line of sight between the first node and the second node.
