PROBLEM TO BE SOLVED: To improve dust exhaust efficiency inside a conveyance elevator for supplying reaped grain culm from a reaper to a thresher.SOLUTION: A conveyance elevator (20) includes a conveyor (25) in a conveyance case (24) that is formed of left/right side plates (21), a baseplate (22), and a top plate (23) into a square cylindrical shape, and a dust suction/exhaust fan (33) is provided at the top plate (23) for sucking and exhausting dust in the conveyance case (24). The dust suction/exhaust fan (33) includes, at a rear side thereof, a plate-shaped dust suction/exhaust guide body (41) that guides the dust flowing therein from a supply port (34), so as to be sucked in the dust suction/exhaust fan (33) by an action of the dust suction/exhaust fan (33) for sucking the inside of the conveyance case (24). The upper part of the guide body (41) is fitted to the rear part of a frame body (38) of a dust suction/exhaust box (35) incorporating the dust suction/exhaust fan (33) in the top plate (23). |
