Description
Technical field
The utility model relates to a kind of engine exhaust silencer of combine-harvester, belongs to combine-harvester exhausting silencer technical field.
Background technique
The exhausting silencer system of tradition combine-harvester is formed by Bolt Connection by exhaust pipe assembly and muffler assembly, and coupling flange on the outlet pipe and exhaust steel pipe are welded into the rigidity overall structure, its shortcoming is that assembling is poor, because the vibrations that produce during engine operation are bigger, and easily cause the infringement of exhaust silencer.Moreover, because the mechanism that do not put out a fire in the sound attenuation assembly, and may eject Mars in the exhaust emissions of motor, easy initiation fire, and have potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and the damping fire extinguishing is respond well, assembles the engine exhaust silencer of easy combine-harvester.
The utility model is that the technological scheme that achieves the above object is: a kind of engine exhaust silencer of combine-harvester, comprise exhaust pipe assembly and muffler assembly, it is characterized in that: described exhaust pipe assembly is welded by outer exhaust steel pipe, corrugated stainless steel tubing and interior exhaust steel pipe successively, and the end face of the end face of outer exhaust steel pipe and interior exhaust steel pipe is respectively equipped with outer mounting flange and interior mounting flange; Described muffler assembly comprises fire extinguishing housing, suppressor case and silencing apparatus noise abatement net and fire extinguishing rack, the fire extinguishing housing is welded on suppressor case one side, fire extinguishing rack with filter screen is installed in the fire extinguishing housing, at least two silencing apparatus noise abatement nets are installed in the suppressor case at interval, the relief opening bend pipe is fixed on fire extinguishing housing one side, and the suppressor case opposite side is fixed with the flange land; The interior mounting flange of interior exhaust steel pipe connects by fastening piece with the flange land of suppressor case.
The utility model exhaust pipe assembly is welded with corrugated stainless steel tubing between exhaust steel pipe and the interior exhaust steel pipe outside, make discharge means become flexible structure by corrugated stainless steel tubing, rational in infrastructure, by corrugated stainless steel tubing diesel exhaust gas is cushioned because of the play row vibrations that produce in the noise elimination process, therefore make whole exhausting silencer system that good shock-absorbing effect be arranged, especially adopt corrugated stainless steel tubing to make the welding processing precision of exhaust pipe assembly not high, assemble simple and easy, thereby improved assembly performance.The utility model also is provided with the fire extinguishing housing at the rear portion that muffler assembly is positioned at the noise elimination housing, therefore when the interior fire extinguishing rack of tail gas that diesel engine discharges process fire extinguishing housing, knocked out Mars by the fine and closely woven filter screen on the fire extinguishing rack, then tail gas is discharged in the air, has improved operational safety and Security.
