This application is the United States national phase of International Application No. PCT/JP2017/038547 filed Oct. 25, 2017, the disclosures of which is hereby incorporated by reference in its entirety.
The present invention relates to a combine harvester configured to, by power of a built-in engine, reap planted grain culm while traveling, and perform a threshing process of threshing the reaped grain culm with a threshing device, and also store grain obtained by the threshing process in a grain tank.
This type of combine harvester is provided with a travel driving device that drives a traveling device, and a grain discharging device that discharges grain to be stored in the grain tank to the outside. Conventionally, a configuration is adopted in which the engine is provided on a lateral side of the threshing device, and while power from the engine is transmitted from an output shaft of the engine to the travel driving device, power is transmitted from the output shaft of the engine to the grain discharging device through a dedicated transmission mechanism (for example, see Patent Document 1).
FIG. 1 is an overall right side view of a combine harvester.
FIG. 2 is an overall left side view of the combine harvester.
FIG. 3 is a plan view of the combine harvester.
Below, with reference to the accompanying drawings, an example will be described in which an embodiment of a combine harvester according to the present invention is applied to an ordinary combine harvester.
Overall Configuration
As shown in FIGS. 1 to 3, the combine harvester is provided with a reaping transport unit 1 that reaps a crop and transports it rearward, a driving portion 3 covered with a cabin 2, a threshing device 4 that performs a threshing process of processing articles reaped by the reaping transport unit 1, a grain tank 5 that stores grain obtained by the threshing process by the threshing device 4, a motor 6 having an engine 21 as a power source, and left and right traveling units 7 positioned on both left and right sides of the vehicle body. Each of the left and right traveling units 7 includes a front wheel 8 as a front side traveling device that cannot be steered and is rotationally driven, and a rear wheel 9 as a rear side traveling device that can be steered.
