摘要：
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).
