    • A draper platform (100) for an agricultural combine that has a first frame section (104) with a first endless conveyor belt (132, 126) wrapped around a first inner roller (254, 258) and a first outer roller (251), the first outer roller (251) having a first axis of rotation; a second frame section (102, 106) supported on the first frame section (104) having a second endless conveyor belt (124, 130) wrapped around a second inner roller (249) and a second outer roller (251), the second inner roller (249) having a second axis of rotation; a first pivot joint (110, 114) coupling the first frame section (104) to the second frame section (102, 106), such that the second frame section (102, 106) pivots with respect to the first frame section (104) about an axis (108, 112) that extends generally parallel to the first outer roller (251) and the second inner roller (249), and in which the first pivot joint (110, 114) maintains a constant distance between the first outer roller (251), and the second inner roller (249) when the second frame section (102, 106) pivots with respect to the first frame section (104) about the axis (108, 112).
    • 1.一种用于农业联合体的刮板平台(100),其具有第一框架部分(104),所述第一框架部分(104)具有缠绕在第一内部辊(254,258)和第一外部辊(251)周围的第一环形传送带(132,126) 第一外辊(251)具有第一旋转轴线; 支撑在第一框架部分(104)上的第二框架部分(102,106)具有围绕第二内部辊(249)和第二外部辊(251)缠绕的第二环形输送带(124,130),第二内部 辊(249)具有第二旋转轴线; 第一枢转接头(110,114),其将所述第一框架部分(104)联接到所述第二框架部分(102,106),使得所述第二框架部分(102,106)相对于所述第一框架部分(104)枢转, 围绕大体上平行于第一外辊(251)和第二内辊(249)延伸的轴线(108,112),并且其中第一枢转接头(110,114)保持第一外辊之间的恒定距离 (102,106)围绕所述轴线(108,112)相对于所述第一框架部分(104)枢转时,所述第二内部辊(251)和所述第二内部辊(249)。
