BACKGROUND OF THE INVENTION
The present invention relates to a combine equipped with a grain discharging device.
[0002]
[Prior art]
When harvesting napped cereals with a combine, the harvested cereals harvested by a reaper provided at the front of the combine are transported by the reaper, supplied to a threshing machine provided at the rear, and threshed by the thresher. Then, the threshed grain is lifted by the whipping device, supplied into the grain storage tank, and temporarily stored in the grain storage tank.
[0003]
When discharging the stored grain out of the machine, the grain in the grain storage tank is supplied from the grain storage tank into the vertical transfer cylinder, and then transferred from the vertical transfer spiral built in the vertical transfer cylinder. After being transported and supplied into the cylinder, and then transported and supplied into the front transport cylinder by the rear transport spiral installed in the transport cylinder, transferred and transferred by the front transport spiral installed in the front transport cylinder, the front end of the front transport cylinder It is discharged out of the machine through the shed at the bottom of the discharge tube provided in the section.
[0004]
Also, when storing the combine in the storage room, when traveling on the road, and when traveling between fields, the operator is once from the cockpit, and the front transfer cylinder is rotated to be folded and rear transferred. The front transfer cylinder is positioned on the side of the cylinder to be in the storage state, and stored in the barn and travels at times other than during the harvesting operation.
[0005]
[Problems to be solved by the invention]
When turning the front transfer cylinder provided at the front end of the rear transfer cylinder to the folded state or working state, the operator who has boarded the cockpit is once out of this cockpit and performs the rotation operation. Otherwise, it cannot be in the folded state or the working state, and for this reason, these operations have been troublesome. However, the present invention intends to solve this problem.
