A dust suction apparatus of an intake pipe is provided to supply external air to an engine maximally by preventing exhaust gas including lean oxygen from being flowed in the intake pipe. A dust suction apparatus of an intake pipe(4) comprises a rotatable dust transporting device by receiving signals from a sensor. The exhaust gas of a dust chamber(2) is not flowed in the intake pipe due to a closed structure while a dust transport device transports the dust piled up to the intake pipe and returns back again.
