Self-propelled crushing machine and method of controlling the same

摘要

A mobile crusher includes: a crusher that crushes raw material; a discharge conveyor being disposed on a downstream side of the crusher to discharge the material crushed by the crusher; an engine that serves as a driving source at least for the crusher and the discharge conveyer; a fuel injection quantity controlling unit that controls a speed of the engine; a crusher pressure sensor that determines a change in a load of the crushed material in the crusher; and a pressure sensor that determines presence or absence of the crushed material to be discharged on the discharge conveyor. When the crusher pressure sensor determines that the load on the crusher is reduced and the pressure sensor determines that the crushed material is not present on the discharge conveyor, the fuel injection quantity controlling unit lowers the speed of the engine to a decelerated speed.
