Oscillating aerator

The utility model discloses an oscillating aeration machine which comprises a first feeding cylinder, a feeding cover arranged on the first feeding cylinder in a covering mode, a second feeding pipe connected to the feeding cover and a mixing cylinder connected to the feeding cover, the first feeding cylinder and the mixing cylinder are coaxially arranged, an oscillating assembly is arranged in the mixing cylinder, and the oscillating assembly is connected with the second feeding pipe. A push-pull rod is fixed to the oscillation assembly, and the end, away from the oscillation assembly, of thepush-pull rod penetrates through the mixing barrel to be connected with a reciprocating telescopic motor fixed outside the mixing barrel. In order to improve the dispersion effect of gas in liquid, an oscillating assembly is further arranged in the mixing barrel, and the oscillating assembly is driven by a reciprocating telescopic motor to reciprocate in the mixing barrel, so that the mixing effect of gas and liquid can
