Abstract: An improved root crop harvester having a narrow and compact processing chassis adapted to simply and easily receive header assemblies of differing capacities. The header assemblies include a transverse roll conveyor for gathering roots received from the digger wheels into a stream for discharge through a central opening in the transverse conveyor to a fore-and-aft extending roll conveyor carried by the processing chassis. The fore-and-aft roll conveyor is inclined upwardly from front to rear to increase the scrubbing and tumbling action and is also provided with a reversing roll section at its rearward end to discharge the roots to the side. The fore-and-aft conveyor is also sloped across its width at its rearward end to aid in discharging roots transversely to the roll conveyor length. The conveyors on the processing chassis are carried between the support wheels to reduce side drafts, minimize wheel slippage in wet field conditions and improve transport maneuverability.

Abstract translation: 一种改进的根系收割机具有窄且紧凑的处理底盘，其适于简单且容易地接收不同容量的集管组件。 集管组件包括横向辊式输送机，用于将从挖掘机轮收到的根部收集到流中，以通过横向输送机中的中心开口排放到由处理底盘承载的前后延伸的辊式输送机。 前后辊式输送机从前到后向上倾斜以增加洗涤和翻滚作用，并且在其后端还设置有反转辊部分以将根部排出到侧面。 前后输送机在其后端也在其宽度上倾斜，以帮助横向于卷筒输送机长度排放根部。 处理底盘上的输送机承载在支撑轮之间，以减少侧面通风，最大程度地减少湿地条件下的滑轮滑移并提高输送机动性。

Abstract: A double-coil spring tine is pivotally attached to a channel-shaped mounting bar of a harrow unit by a removable bracket. The portion of the tine connecting the coils is held loosely next to the mounting bar by the bracket so that the entire tine can pivot about the axis of the attaching portion. The portion of the tine on either side of the bracket is placed in tension rather than subjected to bending. Tines are individually replaceable without need to disassemble the mounting bar.

Abstract translation: 双螺旋弹簧齿由可拆卸的支架枢转地连接到耙单元的通道形安装杆上。 连接线圈的齿的部分通过支架松动地保持在安装杆的旁边，使得整个齿可围绕附接部分的轴线枢转。 托架两侧的齿部分处于张力状态，而不是弯曲。 齿轮可单独更换，无需拆卸安装杆。
