Screw conveyor and roller drive for screw conveyor

The screw conveyor has rollers (110) extending from a bottom (112) to a top (114) and having a transition height. The roller (110) comprises a plurality of drive levers (120), each having a drive side parallel to the axis of rotation (a) of the roller (110). The drive side extends lengthwise from the transition height to a top (114) of the roller (110). The drive rods (120) are spaced around the periphery of the roller (110). The roller (110) includes a plurality of transition members (130), each having a drive surface. At least a portion of each drive surface is at an angle to the axis of rotation (a) of the roller (110) such that, over the feed distance, the peripheral position of the drive surface of each transition member (130) advances a contraction distance d of the respective modular belt. 螺旋输送机具有从底部(112)延伸到顶部(114)并具有过渡高度的辊(110)。所述辊(110)包括多个驱动杆(120)，每个驱动杆具有平行于辊(110)的旋转轴线(a)的驱动侧。驱动侧在长度上从过渡高度延伸到辊(110)的顶部(114)。驱动杆(120)围绕辊(110)的周边间隔开。辊(110)包括多个过渡构件(130)，每个过渡构件具有驱动表面。每个驱动表面的至少一部分与辊(110)的旋转轴线(a)成一角度，使得在进料距离上
