<p>PROBLEM TO BE SOLVED: To provide a hydraulic circuit for a compost agitating machine which promotes the composting of compost materials. SOLUTION: The discharged oil from a working machine pump 43 connected to the output shaft of a motor 40 is distributed via a flow dividing value 64 to hydraulic cylinders 4L, 4R and 5 for driving booms and buckets and to a hydraulic motor 28 for rotating a rotor, respectively and the discharged oil from a gear pump 44 is distributed via a flow dividing valve 65 to the hydraulic motor 28 for rotating the rotor and hydraulic motors 36 and 37 for driving belt conveyors, respectively. As a result, the compost materials are agitated by the rotor 9 and are transported to the bucket sides of the belt conveyors 6 and 7, by which the composting is accelerated. In this case, an angle of inclination of an HST pump 41 is reduced by the operation of an inching pedal 51 and the greater part of the output from the motor 40 is utilized for driving the working machine.</p> |
