ACCELERATOR-CONTROLLING APPARATUS FOR COMBINE, ETC.

摘要

PROBLEM TO BE SOLVED: To suppress the variation of the rotational speed of an engine and keep the speed within the region of rated rotational speed as far as possible by the automatic operation of an acceleration lever. SOLUTION: The accelerator-controlling apparatus of a combine, etc., enabling the control of the rotational speed of the engine with an acceleration lever 1 is provided with a mode-detecting means 5 to detect the mode for reaping a ridge side, reaping lodged crops and reaping on a paddy field. The acceleration lever 1 is shifted by a prescribed amount toward the increasing side by the detection of reaped and transferred crop with the culm sensor 4 when the acceleration lever 1 is set to keep the rotational speed of the engine at the rated speed in the no-load driving of the thresher 2 and the shifted lever is returned to the rated rotational speed after the lapse of a prescribed time or after running a prescribed distance. The control of the rated rotational speed by the acceleration lever 1 at the work of each mode is set to the region near the lower limit of the allowable region of the rotational speed.
