摘要： Snapping unit for heads of harvesting machines, including a pair of counter-rotating snapping rolls and a support and motion transmitting unit with which the snapping rolls are associated so as to cooperate with each other when placed into rotation around their longitudinal axis, each snapping roll including a body where a cylindrical rear portion and a frustoconical front portion are defined, the side wall of the body being provided on its outer surface with longitudinal helical grooves defining helical protrusions ending in corresponding helical ridges capable of penetrating the groove defined between the helical ridges of the adjacent roll during rotation of the two snapping rolls, wherein the helical grooves and, correspondingly, the helical protrusions and the respective helical ridges have a pitch at least equal to the total length of the corresponding roll and extend on at least part of the frustoconical portion.
摘要翻译：收割机头部的捕捉单元，包括一对反向旋转的卷绕辊以及支撑和运动传递单元，夹持辊与其相关联以便当围绕其纵向轴线旋转时彼此配合，每个捕捉辊包括限定圆柱形后部和截头圆锥形前部的主体，主体的侧壁在其外表面上设置有纵向螺旋槽，该纵向螺旋槽限定螺旋突起，该螺旋形突出部终止于能够穿过限定在螺旋脊在两个咬合辊的旋转期间相邻辊的螺旋槽，以及相应地螺旋突起和相应的螺旋脊具有至少等于相应辊的总长度的间距，并且在至少部分截头圆锥体部分。
