Definitions

  • the present invention relates to a paver or a feeder.
  • the FR 2 170 753 A5 describes an exhaust system which is arranged under a hood of a construction machine.
  • the exhaust system includes an engine from which an exhaust pipe extends toward a finned opening.
  • the exhaust pipe includes a bent pipe end which introduces the exhaust gases from the engine into the opening for exhaust gases to exit the opening together with a flow of cooling air generated by a fan and a radiator.
  • the US 5,228,530 A refers to a lawn mower tractor whose drive is located under a hood behind the driver's seat.
  • the drive comprises an engine, are guided by the exhaust gases via an exhaust pipe and a damper to an exhaust port with an exhaust grill.
  • the exhaust gases leave the drive from an exhaust pipe section and are then transported out with a cooling air flow, which is generated by a radiator and a fan, through the exhaust port with exhaust grille.
  • the US 4,872,308 A refers to a work machine with a drive unit that includes a damper.
  • the damper is cooled by compressed cooling air, which is generated by a fan, so that a risk of fire in the engine compartment can be reduced.
  • a mixing chamber is arranged to mix the exhaust gases flowing out of the damper together with cooling air and to guide to an outlet opening of the hood.
  • US 2008/0115989 A1 discloses an exhaust system of a bus, which is arranged in a rear part of the bus in an engine compartment diesel engine connected to an outside of the engine compartment in a chimney chamber exhaust aftertreatment system, with exhaust gases and waste heat of the engine provided in the roof of the bus openings to the surroundings of Omnisbusses above of the badger.
  • the invention is based on the object to improve a construction machine by means of simple structural features to the effect that exhaust gases of the construction machine can be kept away from the operator.
  • the exhaust pipe is not arranged on the hood of the construction machine.
  • the exhaust pipe is arranged in the engine compartment, wherein the exhaust pipe terminates under the hood.
  • the exhaust pipe already ends under the hood, the operator has an improved visibility during operation of the construction machine.
  • the exhaust pipe can be protected under the bonnet from dirt and bad weather conditions, whereby the functionality of the exhaust pipe improved and the life can be increased.
  • the exhaust pipe comprises at least one exhaust gas outlet, which gives the exhaust gas flow an outlet direction and also ends under the hood.
  • the exhaust pipe comprises at least one exhaust gas outlet, which gives the exhaust gas flow an outlet direction and also ends under the hood.
  • an exhaust gas outlet opening is provided in the bonnet, which is aligned with the exhaust pipe or with the exhaust gas outlet nozzle fluidly.

  • FIG. 1 also shows that in the hood 3 an exhaust gas outlet opening 6 is provided, which is aligned with the exhaust pipe 4 or in this case with the exhaust gas outlet 5 flow.
  • the exhaust gas outlet opening 6 is shaped such that an exhaust gas flow is led away from the front of the hood 3 and therefore also by the operating personnel.
  • an exhaust air opening 7 is provided in the engine hood 3, which is fluidly connected to a cooling fan 102.
  • the cooling fan 102 transports the waste heat of the motor 101 to the exhaust air opening 7, where the cooling air flow leaves the engine compartment 2 as exhaust air flow.
  • the exhaust air opening 7 occupies a larger part of the surface of the engine hood 3 than the exhaust gas outlet opening 6.
  • the exhaust gas outlet opening 6 is located in a lower left region of the exhaust air opening 7.
  • the exhaust outlet 6 Along two sides of the exhaust port 7 is the exhaust outlet 6, wherein the exhaust outlet 6 is disposed in front of and next to some flow ribs 8, so that the exhaust air flow when leaving the exhaust port 7 the exhaust gas from the exhaust port 6 coming forward from the hood 3 entrains. It is also provided that the exhaust air flow guided by the upper flow ribs 8 flows out via the exhaust gas outlet opening 6, thereby covering the outflowing exhaust gases from the exhaust gas outlet opening 6, so that the exhaust gases are kept away from the operating personnel.
  • an exhaust aftertreatment device 9 is flanged to the exhaust pipe 4.
  • the exhaust aftertreatment device 9 is located within the engine compartment 2, below the hood 3.
  • the exhaust aftertreatment device 9, for example, a particulate filter, a catalyst, a Silencer etc. includes, an optimal removal of combustion gases from the internal combustion engine safely.
  • FIG. 2 shows a motor assembly 200, as it is usable for a construction machine 100 according to the invention.
  • a diffuser 103 connected to the exhaust aftertreatment device 9 through the exhaust pipe 4.
  • the diffuser 103 is provided for diluting and cooling the combustion gases.
  • the motor assembly 200 of the FIG. 2 is not shown installed in the engine compartment 2, according to the invention, the diffuser fluidly with the in FIG. 1 aligned exhaust outlet 6 and does not protrude out of this.
