GRAIN UNLOADING CONTROLLER OF COMBINE HARVESTER OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To prevent residual grains remaining in an unloading cylinder provided in a grain transfer unloading cylinder apparatus for transferring the grains and unloading the grains to the outside of a machine body. SOLUTION: The grains are unloaded from a grain unloading port 14a of the unloading cylinder 14 of the grain transfer unloading cylinder apparatus 6 for transferring the grains to the outside of the machine body. When the grain unloading port 14a of the unloading cylinder 14 is rotated and moved to a position other than that just under the unloading cylinder after completing the unloading of the grains, the grain unloading port 14a is composed so as to be rotated and controlled once to the position just under the unloading cylinder with a controller 21f when completing the unloading of the grains. The speed of an engine 21c is not changed and controlled to the rated speed until the unloading cylinder 14 reaches an unloadable region when the grain transfer unloading cylinder apparatus 6 is kept in a state of unloading the grains and the unloading cylinder 14 is not in the unloadable region. Furthermore, the grain unloading port 14a is composed so as to be rotated and moved to the upper side before the grain transfer unloading cylinder apparatus 6 is controlled to a housed position.
