Abstract

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.

First claim

The invention claimed is:

1. A mobile recycler, comprising:
an engine generating driving force;
an engine frame on which said engine is mounted;
a track frame attached below said engine frame;
a pair of traveling apparatuses supported on said track frame and having a crawler belt;
a work implement mounted on said engine frame;
a discharge conveyor extending forward between said pair of traveling apparatuses and transporting a disposed object discharged from said work implement;
an exhaust gas treatment device treating an exhaust gas from said engine through reduction reaction; and
a reducing agent tank storing a reducing agent supplied to said exhaust gas treatment device,
said reducing agent tank being arranged in front of a front end of said crawler belt and in rear of a front end of said track frame in a fore/aft direction, below said engine frame at a distance from the engine frame such that a bottom surface of the reducing agent tank is arranged at a position lower than an upper surface of said crawler belt.

2. The mobile recycler according to claim 1 , wherein
said reducing agent tank is superimposed on said crawler belt in the front view at a position adjacent to the front end of said crawler belt.

3. The mobile recycler according to claim 1 , wherein
said crawler belt has a ground engaging surface coming in contact with a ground, and
said reducing agent tank is arranged above a straight line which passes through a portion of said discharge conveyor protruding most on a side of the ground with respect to a direction of movement of said disposed object and a front end of said ground engaging surface in a side view.

4. The mobile recycler according to claim 1 , further comprising a control panel for operating said mobile recycler, wherein
said reducing agent tank is arranged adjacent to said control panel.

5. The mobile recycler according to claim 1 , further comprising a pump for transferring said reducing agent, wherein
said pump is arranged between said engine frame and said reducing agent tank.

6. The mobile recycler according to claim 1 , wherein
said reducing agent tank is supported by said track frame.
