Such a mobile recycler that an operator can replenish a reducing agent tank with a reducing agent from the ground is provided. A reducing agent tank stores a reducing agent supplied to an exhaust gas treatment device treating an exhaust gas from an engine through reduction reaction. A tank case accommodates the reducing agent tank. The tank case has a support base supporting a container of the reducing agent for replenishment to the reducing agent tank.

Mobile recycler

Such a mobile recycler that an operator can replenish a reducing agent tank with a reducing agent from the ground is provided. A reducing agent tank stores a reducing agent supplied to an exhaust gas treatment device treating an exhaust gas from an engine through reduction reaction. The reducing agent tank is arranged in front of a front end of a crawler belt and in the rear of a front end of a track frame in a fore/aft direction. The reducing agent tank is arranged as being superimposed on the crawler belt in a front view, below an engine frame at a distance therefrom.

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.

Self-propelled crushing machine and method of controlling the same

A mobile crusher includes: a crusher for crushing raw materials; a discharge conveyor provided on a lower stream of the crusher for discharging the raw materials crushed by the crusher; a work implement provided on an upper stream of the crusher for producing the crushed materials; a conveyor sensor and conveyor pressure comparing unit for determining whether the crushed materials to be discharged are fed on the discharge conveyor or not; a crusher pressure sensor and crusher pressure comparing unit for determining whether the raw materials are present in the crusher or not; and a flow rate controller for controlling the speeds of the crusher, discharge conveyor and work implement based on determination results of the conveyor pressure sensor, conveyor pressure comparing unit, crusher pressure sensor and crusher pressure comparing unit.

Mobile crusher

A mobile crusher includes: a crusher having a fixed jaw and a swing jaw and adjusting an outlet gap between lower ends of the fixed jaw and the swing jaw, the crusher crushing raw materials by swing movement of the swing jaw toward the fixed jaw and discharging the raw materials crushed by the crusher from the outlet gap to produce crushed materials; a work implement disposed on an upper stream or a lower stream of the crusher to produce the crushed materials; and a controller that controls a work implement speed of the work implement depending on the outlet gap.

A self-traveling crushing machine includes: a traveling device; a crushing device that is provided on the traveling device and crushes a to-be-crushed object supplied; an overload escaping section that escapes an overload of the crushing device; and a controller that controls the crushing device. In the self-traveling crushing machine, the crushing device is a jaw crusher in which the to-be-crushed object is supplied to a V-shaped space formed by a fixed jaw and a movable jaw and the movable jaw swings relative to the fixed jaw to crush the to-be-crushed object, and the controller includes: an escape-operation determining section that determines whether or not the overload escaping section has operated; and an information output section that sends the escape operation information to an outside when the escape-operation determining section determines that the escape operation has been conducted.

Self-propelled crusher and management system for self-propelled crusher

A mobile crusher, which has a high-quality controlling function enabling an efficient production, and which is capable of preventing the crusher itself from being damaged, is provided. For this purpose, a mobile crusher having a feeder ( ) and a crusher member ( ) which are set drivably on a mobile vehicle body ( ), includes means ( ) for detecting an amount of a material to be crushed, which detects an amount (H) of a material ( ) to be crushed inside the crusher member ( ), and control means ( ) for receiving the amount H from the means ( ) for detecting the amount of the material to be crushed and controlling a driving speed V of the feeder ( ) changeably based on the reception amount H.
