Problems solved by technology

[0002] The muffler is a device that prevents sound transmission and allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. In construction machinery, mufflers are generally installed, and the exhaust port of the muffler is located on the top surface of the construction machinery, directly opening In the open air, and construction machinery is generally parked in the open air, it is easy to cause rainwater to enter the muffler and then enter the engine, causing rust inside the engine, and even serious failures such as broken pistons and bent connecting rods
