    • A ground contact height sensor for a harvesting header comprises a transverse rotatable shaft, a first rigid arm, a second rigid arm and a connecting member. The rotatable shaft is rotatively mounted to the frame of the header. The first rigid arm is rigidly mounted to the rotatable shaft. The first arm extends downwardly and rearwardly from the rotatable shaft in a curved manner. The second rigid arm is pivotally coupled to the first rigid arm by a hinge joint. The second rigid arm extends upwardly and rearwardly from the second end of the first rigid arm. The first and second rigid arms defining a relatively large radius. The connecting member secures the rearmost end of the second rigid arm to the frame of the header. To maintain the radius of the two pivotally connected rigid arms the hinge joint joining the two rigid arms is provided with a torsion spring.
    • 用于采集头的接地高度传感器包括横向可旋转轴,第一刚性臂,第二刚性臂和连接构件。 旋转轴可旋转地安装在集管的框架上。 第一刚性臂刚性地安装到可旋转的轴上。 第一臂以可弯曲的方式从旋转轴向下和向后延伸。 第二刚性臂通过铰链接头枢转地联接到第一刚性臂。 第二刚性臂从第一刚性臂的第二端向上和向后延伸。 第一和第二刚性臂限定相对较大的半径。 连接构件将第二刚性臂的最后端固定到集管的框架。 为了保持两个枢转连接的刚性臂的半径,连接两个刚性臂的铰链接头设置有扭转弹簧。
