<P>PROBLEM TO BE SOLVED: To solve such problems as a decline in efficiency of removing dust inside a conveying elevator for conveying grain culms from a reaper to a thresher, and contamination of grains, etc. <P>SOLUTION: A base of the reaper 6 is attached to the distal end of the conveying elevator 20 connected to the thresher 3. The conveying elevator 20 includes a conveyor 25 inside a square pillar-shaped conveyor case 24, and a swelling part 30 is formed at a prescribed position in the middle in the longitudinal direction of a top plate 23 of the conveyor case 24. A dust sucking and discharging fan 33 for sucking dust within the conveyor case 24 is disposed on a distal end top plate 32 at a position more toward the distal end side than the swelling part 30. A rotation axis 37 of the dust sucking and discharging fan 33 is inclined so that the longer one of the distance from the attached part of the conveyor case 24 with the reaping device 6 to a left sidewall 10L and the distance from the attached part to a right sidewall 10R is lower than the other side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
