The invention discloses a labyrinth type diesel engine breather provided with sloping baffles. The labyrinth type diesel engine breather is structurally characterized in that a mixed gas inlet pipe is arranged above a breather outer cover, and mixed gas enters a cavity through the gas inlet pipe from the lower end of the breather outer cover; the breather outer cover and the mixed gas inlet pipe adopt integral totally-closed design, and the gas inlet mode is a bottom-up mode; the breather is provided with a gasket, multiple layers of sloping baffles are arranged in the breather outer cover, and filter screens are arranged between adjacent layers of sloping baffles; gaps are reserved between each baffle and the inner wall of the outer cover as well as between vertical baffles to serve as oil return chutes, a gas outlet pipe is arranged on the side surface of the upper end of the breather, and a lining pipe is inlaid in the gas outlet pipe; an oil return pipe is arranged at the bottom end of the breather, an oil return cavity pressure stabilizing chamber is formed between the lower end of the inner wall of the breather outer cover and the oil return pipe, and oil gas in the breather and engine oil flow in opposite directions. Compared with the conventional breather, residual engine oil mist can be filtered out effectively, consumption of lubricating oil is reduced, and pollution on atmospheric environment is reduced obviously.
