PROBLEM TO BE SOLVED: To provide a combine in which the shredding of waste straw discharged from a threshing processing space is desired so as to be performed satisfactorily.SOLUTION: The combine includes a flow-down guide plate 54 with multiple fixed blades 48 provided in a waste straw shredder and provided from a lower end of an inlet opening 55 over a shred outlet opening 56, a shredding unit 49 for shredding waste straw using rotary blades 47 and fixed blades 48, and a box-shaped cover 46 for covering the shredding unit 49 from the upper side. The flow-down guide plate 54 is linearly extended from the lower end of the inlet opening 55 over the shred outlet opening 56 in side view. Among portions positioned in the inlet opening 55 side in an outer circumferential part of the shredding unit 49, a portion being the inlet opening 55 side from a sideways-facing shaft core P3 and being the opposite side to the flow-down guide plate 54 to the sideways-facing shaft core P3 in side view is covered by a waste straw transfer direction front end in a ceiling member 50 of the cover 46.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】扱処理空間から排出された排ワラの細断処理を良好に行えるようにすることが望まれていた。【解決手段】排ワラ細断装置に、複数の固定刃４８が設けられ、かつ、投入口５５の下端部から細断物放出口５６にわたって設けられた流下案内板５４と、排ワラを回転刃４７と固定刃４８とによって細断する細断部４９と、細断部４９を上側から覆う箱形状のカバー４６と、が備えられ、流下案内板５４は、側面視で、投入口５５の下端部から細断物放出口５６にわたって直線状に延ばされ、細断部４９の外周部における投入口５５側に位置する部分のうち、側面視で横向き軸芯Ｐ３よりも投入口５５側であって且つ横向き軸芯Ｐ３に対して流下案内板５４とは反対側の部分が、カバー４６の天井部材５０における排ワラ移送方向前端部によって覆われている。【選択図】図５
