摘要： PROBLEM TO BE SOLVED: To restrain noise in an engine room leaked from a vent hole formed on a resistance plate and thereby improve working environment. SOLUTION: An opening part 25 of a dust-proofing structure for sucking the outside air for cooling is formed on the outside of a frame body 26 forming the engine room 45. The resistance plate 48 for intake negative pressure diffusion is disposed on the inside of the opening part 25. The plural vent holes are formed on the resistance plate 48 in such a manner of pointing almost along a surface of the resistance plate.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for nipping and conveying plant feet of a combine harvester capable of readily and rapidly carrying out removing operations of clogged grain culms. SOLUTION: This apparatus is obtained by composing a guide rail 28 for backup capable of rotating and guiding each endless rotating unit 18 in a posture along a nipping and conveying passage so that the position thereof can be changed from a backup position for coming into slide contact with the endless rotating unit 18 to a position for releasing the backup, composing a rotating wheel 21 for applying a tension to the endless rotating unit 18 so that the position thereof can be changed from a protruding position to an evacuating position and composing a holding means 29 for holding the position capable of holding the guide rail 28 at the backup position and holding the rotating wheel 21 at the protruding position so that the changeover thereof from a state for holding the position to a state for releasing the position holding can be carried out by operation of one operating tool 32.

摘要： PROBLEM TO BE SOLVED: To provide a multi-row reaping combine harvester having a drag for an external force for raising up devices at both left and right ends and prevent scattering of muddy water on the side of an operating part when a power distribution shaft in the upper part is omitted to carry out power transmission from the lower part in the multi-row reaping combine harvester equipped with the three or more raising up devices. SOLUTION: This multi-row reaping combine harvester is composed by connecting mutual upper parts of the raising up devices 7 at left and right ends except an intermediate raising up device 7 in the three or more raising up devices 7 with an upper part connecting member 40 without having an internally installed space of a power distributing means to the respective raising up devices 7 and composing the upper part connecting member 40 of a member having a larger width in the front and rear directions than that in the direction along a claw rotating surface so as to detour a raising up passage in a part located on the upper side of the raising up passage formed between the mutual adjacent raising up devices 7 and intersect an extended surface 7L of the claw rotating surface of sites at the terminal end of a raising up stroke of the raising up claws 7e.
