DISCHARGING AUGER STRUCTURE IN COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide the subject structure capable of improving working efficiency and also suppressing the weight increase at the tip side of a discharging auger by constituting a specific discharging auger at the top part of a vertical conveying pipe installed as standing in the rear direction of a grain tank. SOLUTION: This discharging auger structure in a combine harvester is provided by installing a vertical conveying pipe 11 installed with a vertical conveying screw shaft in its inside, as standing in the rear direction of a grain tank 9 arranged closely to a threshing part 10 and a base end side auger part 13 capable of freely rotating horizontally at the top part of the vertical conveying pipe and also juxtaposing a base end side of an extendable auger part 14 extendable in its discharging direction at the side surface in longitudinal direction of the base end side auger part 13 for constituting a discharging auger 12. In this case, it is preferable to arrange transmission mechanisms for supplying a rotary power of the vertical conveying screw shaft to each auger part together on the upper part of the vertical conveying pipe.
