BULLDOZER
A bulldozer comprises a main machine frame (1). An engine (2), a machine cover and a rear exhaust gas processing device (3) are arranged on the main machine frame (1). The air inlet of the rear exhaust gas processing device (3) is connected with the air outlet of the turbine engine (2) through a pipeline. The rear exhaust gas processing device (3) is fixed on the machine cover. Vibration generated by the engine (2) in the bulldozer needs to be transmitted to the main machine frame (1) through an engine supporting frame or a shock-absorbing device, and then is transmitted to the machine cover through the main machine frame (1). The vibration transmission path is long, and the vibration damping becomes complex and the damping value is high. The vibration transmitted to an air filter (4) is very small, and the vibration of the main machine frame (1) caused by the working of a scraper knife working device is also transmitted to the rear exhaust gas processing device (3) through the main machine frame (1), the machine cover, the shock-absorbing device and the like, so that the vibration transmission path is long, and the rear exhaust gas processing device (3) is accordingly less influenced by vibration caused by working of the working device. The rear exhaust gas processing device (3) is arranged on the machine cover, so the length of an exhaust pipeline can also be shortened, the pipeline arrangement can be optimized, and the system working reliability can be improved.
