Raw cattle feed fermentation vessel inner wall cleaning auxiliary mechanism

The invention discloses a raw cattle feed fermentation vessel inner wall cleaning auxiliary mechanism. The mechanism comprises a fermentation vessel body, a feeding hopper installed on the surface of one side of the fermentation vessel body, a water pumping assembly at the edge position of the top end of the fermentation vessel body, a water accumulation tank installed on the water pumping assembly and a discharging valve pipe installed at the bottom end of the fermentation vessel body. A double-shaft motor is mounted in the middle of the top end of the fermentation vessel body, an output shaft at the bottom end of the double-shaft motor extends into the fermentation vessel body, an air drying mechanism is mounted at the position, located at the outer side of a rotating fan, of the inner wall of the fermentation vessel body, and a transmission rod is mounted at the bottom end of the rotating fan. By arranging a series of structures, the interior of the fermentation vessel body is rapidly heated, part of bacte
