摘要： A safety stand for minimizing the effect of hydraulic failure in an agricultural harvester is disclosed. In one embodiment, a system for raising or lowering a pivotable safety stand is provided which may take the form of a remotely operated hydraulic safety stand. In another embodiment, the mechanical stop provides multiple stops along the length of travel of the piston to prevent the dramatic falling of the feeder arm under the force of gravity. In one embodiment, the safety stand is provided with a series of notches along a longitudinal edge of the safety stand which are designed to accept and received a protrusion affixed to a cylinder of a hydraulic cylinder which raises and lowers a feeder arm. When the feeder arm is raised, the hydraulic cylinder is in the full upright position, the safety stand can be lowered such that the protrusion enters and is held within a notch to prevent accidental downward movement of the feeder arm. If the notch fails, or the safety stand is not properly engaged, the longitudinal edge of the safety arm is allowed to follow the protrusion, until a subsequent notch is reached, which then engages the protrusion, safely stopping the downward path of the feeder arm.
摘要翻译： 公开了一种用于最小化农业收割机中液压破坏的影响的安全架。 在一个实施例中，提供了用于升高或降低可枢转安全支架的系统，其可以采取远程操作的液压安全支架的形式。 在另一个实施例中，机械止动件沿着活塞的行进长度提供多个止动件，以防止在重力作用下进给臂的急剧下降。 在一个实施例中，安全支架沿着安全支架的纵向边缘设置有一系列凹口，其被设计成接收和接收固定到液压缸的气缸上的突起，该突起升高和降低进给臂。 当进料臂升高时，液压缸处于完全直立的位置，可以降低安全支架，使突起进入并保持在切口内，以防止进给臂的意外向下运动。 如果切口失效或安全支架未正确接合，则允许安全臂的纵向边缘跟随突起，直到达到随后的切口，然后与突起接合，安全地停止进给臂的向下路径 。

摘要： A foreign object detection and removal system for an agricultural combine is provided. The system includes a controller operatively connected to a feederhouse and a chopper assembly. The feederhouse includes an acoustic element for detecting foreign objects and an actuator for opening and closing a door of the feederhouse to remove foreign objection. The chopper assembly includes an actuator to retract a knife bank to allow for the passage of foreign objects through the chopper assembly without causing damage to the chopper assembly.
