THRESHING CONTROLLER FOR COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To improve operation efficiency in hand threshing operation. SOLUTION: The threshing controller for a combine harvester has constitution that the conveyance speed of a threshing feed chain is changed and the conveyance speed of the feed chain is increased with the increase of the vehicle speed of the combine harvester. The threshing controller is equipped with a vehicle speed detection means for detecting the vehicle speed of the combine harvester and a hand threshing detection means for detecting a hand threshing state. When the vehicle speed detection means detects the stopping state of the combine harvester and the hand threshing detection means detects a hand threshing state, the conveyance speed of the feed chain is changed to a high-speed state of a fixed value or above.
