摘要： In the central beater portion of the platform auger of a conventional grain cutting platform for a combine harvester, the finger and finger bearing assemblies are constructed so that each may be removed individually for repair or replacement without disturbing other finger assemblies or the fixed crankshaft on which the finger assemblies are journaled. Each bearing assembly consists of two halves hinged together and closing to define a cylindrical bearing bore embracing the finger shaft. Portions of the two bearing halves opposite the hinge are recessed in their facing surfaces to receive the enlarged butt end of a finger, so as to align, clamp and retain the finger. A single clamping fastener is used to maintain the integrity of the finger and bearing assembly in operation.

摘要： A self-propelled combine harvester is equipped with a grain cutting platform having a floating, flexible cutter bar. The operating height of the grain platform is controlled conventionally by hydraulic cylinders. An automatic operating mode may be chosen in which the hydraulic cylinders are responsive to a signal corresponding to vertical disposition of the floating cutter bar relative to the floor of the platform. The automatic control system includes a sealed self-contained position sensor switch module directly coupled to a sensor rock shaft whose rotational position in the platform frame is representative of the disposition of the cutter bar relative to the platform floor. The sensor switch module includes a segmented printed circuit board and an associated wiper arm with a brush assembly, directly coupled to the sensor shaft. Selector switching means includes a rotary switch at the operator station which the operator can set to control the platform at any one of three operating height set points. A mechanical float range indicator is optionally provided.
摘要翻译： 自走式联合收割机配备有具有浮动的柔性切割杆的谷物切割平台。 谷物平台的操作高度通常由液压缸控制。 可以选择自动操作模式，其中液压缸响应于相对于平台的底板垂直布置的浮动切割杆的信号。 自动控制系统包括一个密封的独立位置传感器开关模块，其直接耦合到传感器岩石轴，其中平台框架中的旋转位置代表了刀具杆相对于平台地板的布置。 传感器开关模块包括分段印刷电路板和与电刷组件相关联的刮水器臂，其直接联接到传感器轴。 选择器切换装置包括操作员站处的旋转开关，操作员可以设置为在三个操作高度设定点中的任何一个上控制平台。 可选地提供机械浮子范围指示器。
