The utility model discloses an automatic stirring device for methane-generating pit, comprising a vertical shaft and a vane wheel in a shape of fan fixed on the lower end of the vertical shaft. The vertical shaft is movably connected with a water seal device fixed on an upper cover of the methane-generating pit; the water seal device comprises a water box and a water seal bushing fixed on the vertical shaft; a water seal column with vertical shaft through hole is arranged on the middle part of the water box; the water seal bushing is covered on the water seal column; the upper end of the vertical shaft is connected with the output shaft of an electrical machine; the electrical machine is supported on the upper cover on the methane-generating pit; a rolling bearing is arranged between an inner cavity of the water seal bushing on the vertical shaft and the upper end of the water seal column. In the utility model, as the electrical machine drives the vane wheel in a shape of fan fixed on the vertical shaft to rotate, the rotation speed is high, and the stirring power is large, the vane wheel in a shape of fan can fully break the encrustation on the upper part of the pit by the fermentation material in order to increase the methane-generating rate, and the operator only need press the corresponding timing button to finish operation, which reduces the labor strength of the operator.
