Abstract
PURPOSE: To accomplish accurate actions according to the matter to be excavated through automation of the manual operation section by memorizing each stage of manual operation as separated from the control section in the operation mechanism of a back hoe working vehicle.
CONSTITUTION: The following stages os the operation are memorized to switch the operation valve to the automatic operation with a control mechanism: The first stage where an arm A is stretched downward to cause the bucket 12 to discharge, the second stage where the arm A is bent to cause the bucket to scoop, the third stage where the arm A is bent upward to cause the bucket to scoop, the fourth stage where with the bucket halted the arm A stretches upward, the fifth stage where with the bucket halted, the arm turns stretching upward, the sixth stage where the bucket acts to discharge with the arm halted, the seventh stage where with the bucket halted, the arm returns turning, and the eight stage where the vehicle retracts. A switching mechanism is provided for the control system of the automatic control mechanism and manual operation mechanism. The automatic control mechanism memorizes the eight kinds of action and repeats the actions as memorized with the release of the manual operation mechanism.
