Abstract
Cold planer exhaust systems and methods of clearing the same are disclosed. The exhaust systems and methods may include an inlet manifold located proximate a milling drum housing and above a material conveyor. The inlet manifold may further include at least one inlet passage and at least one access door configured to open and allow access to an interior of the exhaust system. The systems and methods may further include a ventilator configured to draw dust and fumes into and through the exhaust system.
Claims18
An exhaust system for a cold planer, comprising:
- an inlet manifold located at an exit area of a milling drum housing, downstream, in a direction of travel of milled material, from a milling drum and above a material conveyor, the inlet manifold comprising:
- a top side removably secured to a frame of the cold planer,
- a bottom side positioned below the top side when the top side is removably secured to the frame and including at least one access door configured to open and allow access to an interior of the exhaust system, and
- a bottom inlet plate supported by the bottom side and extending downstream, in a direction of travel of milled material, from the bottom side and angled upwardly toward the top side so that a distance between the top side and the bottom inlet plate decreases as the bottom inlet plate extends downstream, wherein the bottom inlet plate and the top side define at least one inlet passage at a downstream end of the inlet manifold configured to received dust and fumes generated by the milling drum;
- and
- a ventilator in fluid communication with the inlet manifold and the at least one inlet passage, the ventilator configured to draw the dust and fumes from the inlet manifold and the at least one inlet passage to the ventilator.

A cold planer, comprising:
- a frame;
- at least one traction device configured to support the frame;
- an engine supported by the frame and configured to drive the at least one traction device to propel the cold planer;
- a milling drum;
- a material conveyor having a charge end located to receive removed material delivered onto the charge end by the milling drum;
- an exhaust system comprising:
- an inlet manifold located above the charge end of the material conveyor and downstream, in a direction of travel of milled material, of the milling drum, the inlet manifold comprising:
- a top side removably secured to the frame,
- a bottom side positioned below the top side when the top side is removably secured to the frame, and including at least one access door in the inlet manifold configured to open and allow access to an interior of the exhaust system, and
- a bottom inlet plate supported by the bottom side and extending downstream, in a direction of travel of milled material, from the bottom side and angled upwardly toward the top side so that a distance between the top side and the bottom inlet plate decreases as the bottom inlet plate extends downstream, wherein the bottom inlet plate and the top side define at least one inlet passage at a downstream end of the inlet manifold configured to received dust and fumes generated by the milling drum, and
- a ventilator in fluid communication with the inlet manifold and the at least one inlet passage;
- and
- a material deflector supported on the frame and adjacent the at least one inlet passage, the material deflector configured to block material from entering the at least on inlet passage.

A method of cleaning out an exhaust system of a cold planer, comprising:
- providing a cold planer having an exhaust system, the exhaust system including an inlet manifold downstream, in a direction of travel of milled material, of a milling drum, above a primary material conveyor and configured to receive dust and fumes, the inlet manifold comprising:
- a top side removably secured to a frame of the cold planer,
- a bottom side positioned below the top side when the top side is removably secured to the frame and having at least one access door configured to open to allow access to an interior of the exhaust system, and
- a bottom inlet plate supported by the bottom side and extending downstream, in a direction of travel of milled material, from the bottom side and angled upwardly toward the top side so that a distance between the top side and the bottom inlet plate decreases as the bottom inlet plate extends downstream, wherein the bottom inlet plate and the top side define at least one inlet passage at a downstream end of the inlet manifold configured to receive dust and fumes generated by a milling drum;
- opening the at least one access door of the inlet manifold;
- and
- accessing an interior of the inlet manifold and clearing the inlet manifold of any material therein.
