MECHANISM FOR CONTROLLING ROLLING F PADDY FIELD WORKING MACHINE

摘要

PURPOSE: To enable smooth preparation operation by preventing unintentional rolling motion of a working machine and to surely perform the rolling control in a ground-working operation. ;CONSTITUTION: A seedling transplanter is connected to a mobile machine body in a state to enable free rolling around a longitudinal shaft by an electric motor 10d connected through a cushioning spring 13. The seedling transplanter is provided with a level sensor 16 to detect the inclination angle from the horizontal posture based on the ground and the electric motor 10d is controlled to keep the seedling transplanter to a prescribed posture relative to the ground based on the detection result of the level sensor 16. When a potentiometer detects the flotation of the seedling transplanter from the ground, the electric motor 10d is automatically controlled to stop the rolling motion.;COPYRIGHT: (C)1994,JPO&Japio
