Ventilation system for cold planer

Abstract

A ventilation system for a cold planer having a milling drum and a conveyor system are provided. The ventilation system includes an inlet pipe located above the conveyor system adapted to receive dust and fumes generated by the milling drum. The ventilation system also includes an intermediate pipe having a first end and a second end. The first end of the intermediate pipe is connected to the inlet pipe. The intermediate pipe includes an annular chamber and a number of nozzles. The annular chamber is adapted to receive pressurized air from a compressor. The nozzles are fluidly connected to the annular chamber. The ventilation system includes an outlet pipe fluidly connected to the second end of the intermediate pipe, the number of nozzles directs the pressurized air from the compressor towards the outlet pipe to create vacuum at the outlet pipe for ventilating dust and fumes from the inlet pipe.

What is claimed is: 
     
         1 . A ventilation system for a cold planer having a milling drum and a conveyor system, the ventilation system comprising:
 an inlet pipe located above the conveyor system, the inlet pipe being adapted to receive dust and fumes generated by the milling drum;   an intermediate pipe having a first end and a second end opposite to the first end, the first end of the intermediate pipe being connected to the inlet pipe, the intermediate pipe comprising:
 an annular chamber adapted to receive pressurized air from a compressor of the cold planer; and 
 a number of nozzles fluidly connected to the annular chamber; and 
   an outlet pipe fluidly connected to the second end of the intermediate pipe such that the number of nozzles direct the pressurized air from the compressor towards the outlet pipe to create vacuum at the outlet pipe for ventilating dust and fumes from the inlet pipe.
