To provide a combine capable of smoothly opening a threshing cylinder cover having a dust feed lever while facilitating operating the dust feed lever from a driver seat side.SOLUTION: A combine includes: a mechanism of releasing lock of a threshing cylinder cover 12 by vertical operation of an opening/closing handle, and making the threshing cylinder cover 12 vertically and swingably openable and closable, integratedly with a nipping rail above a feed chain; and a mechanism of making an angle of a dust feed valve in a threshing chamber adjustable. A dust feed lever 15 for adjusting a feed angle of the dust feed valve adjustable is projected forward from the top face of the threshing cylinder cover 12 and provided so as to be operated from a driver seat 7 side, in a position between an auger receiving part 10 of a discharge auger 9 mounted on a right machine frame lateral plate of a threshing part 4, and a back mirror 14 mounted on a left front end part of the threshing cylinder cover 12. The dust feed lever 15 is formed by folding into a shape that does not interfere with the auger receiving part 10 in a state of swinging upward and opening the threshing cylinder cover 12.SELECTED DRAWING: Figure 2【課題】送塵レバーを運転席側から容易に操作できるものとしながら、この送塵レバーを備えた扱胴カバーを円滑に開放できるコンバインを提供する。【解決手段】開閉ハンドルの上下操作で扱胴カバー12のロックを解除し、扱胴カバー12をフィードチェンの上側の挟持レールと一体で上下に揺動開閉可能とする機構と、扱室内の送塵弁の角度を調節可能とする機構を備え、送塵弁の送り角度を調節する送塵レバー15を、脱穀部4の右側機枠側板に装着した排出オーガ9のオーガ受け部10と、扱胴カバー12の左側前端部に装着したバックミラー14との間での位置において、扱胴カバー12の上面から前方に延出して運転席7側から操作可能に設け、且つ、この送塵レバー15を、扱胴カバー12を上方に揺動させて開放した状態でオーガ受け部10と干渉しない形状に折り曲げて形成する。【選択図】図2
