Abstract
PURPOSE: To make a bucket working apparatus at the tip of a lift arm move in parallel when the lift arm is elevated, while making an accelerated dumping operate when the working apparatus performs the dumping operation, by gearing lift cyinder with a dump cylinder in series.
CONSTITUTION: Under the condition that both direction control valves 6 and 7 are in neutral, a pump 8 is no load. When one direction control valve is operated the other valve being left in neutral, it can be operated independently. On the occasion, even when the direction control valve 7 for the dump cylinder is operated independently, the working characteristic by an acceleration valve 10 can be obtained. When both direction control valves 6 and 7 are operated simultaneously, the dump cylinder 5 is made to work with the returning oil of a lift cylinder 4 and, in the combination of the lift with the dump and that of the lowering with the scooping motion, in particular, the elevation of the lift arm and the action of the working apparatus at the tip are performed in parallel. In this way, the working efficiency of the front loader for agricultural use can be increased.
