Claims

[Scope of utility model registration request]

The power of an engine 4 having an output shaft 3 extending in the lateral direction of the aircraft is distributed in the counter case 2 to a first drive shaft 5 extending in the longitudinal direction of the aircraft and a second drive shaft 6 extending in the lateral direction. Transmitted from the second drive shaft 6 to the threshing cylinder 7 having a longitudinal rotation axis and from the second drive shaft 6 to threshing work parts other than the handling cylinder 7 having a horizontal rotation axis via transmission belts 8 and 9, respectively. A power transmission structure for a combine harvester configured to
A second bevel gear 23 that meshes with the first bevel gear 24 connected to the drive shaft 5 is loosely fitted onto the second drive shaft 6 and rotates integrally with the intermediate transmission shaft 17 arranged parallel to the second drive shaft 6. a pair of transmission gears 25a,
25b, and one transmission gear 2.
A gear 26 in which the gear 5a is always engaged is provided to rotate integrally with the second bevel gear 23, and the gear 26 is in engagement with the second drive shaft 6 and the extending shaft portion 23a of the second bevel gear 23, and the gear 26 is in engagement with the second bevel gear 23. A shift gear 27 that can be freely shifted and engaged with the second drive gear 25b is fitted onto the second drive shaft 6 by splines, and the first drive shaft 5 is configured to change speed in accordance with the shift operation of the shift gear 27. Combine power transmission structure.
