The present application discloses an exhaust gas after-treatment mixing device including a casing, a mixing pipe and a partition plate fixed on a periphery of the mixing pipe. The partition plate includes a first plate on one side of the mixing pipe, a second plate on the other side of the mixing pipe and a third plate connecting the first plate and the second plate. The mixing pipe includes a first pipe portion and a second pipe portion. The first pipe portion is provided with at least two first openings located on two sides thereof, respectively. The exhaust gas after-treatment mixing device includes a first shielding plate and a second shielding plate shielding front ends of the first openings, respectively, so that most of exhaust gas needs to flow bypass the first shielding plate and the second shielding plate before entering the first openings.
