The utility model relates to the technical field of
fermentation tanks, in particular to an organic water-soluble
fertilizer fermentation tank. Comprising a tank body, a cover and a
discharge port fixedly formed in the bottom of the tank body, and further comprises an exhaust
assembly which comprises an
exhaust pipe fixedly installed on one side of the top of the cover, a circular sliding plate is slidably installed in the
exhaust pipe, a feeler lever is fixedly installed on one side of the circular sliding plate, and a pressure spring is fixedly installed on the side, on the feeler lever, of the circular sliding plate; the side, away from the circular sliding plate, of the pressure spring is fixedly installed in the inner wall of an exhaust port of the
exhaust pipe, a motor is fixedly installed on the side, away from the exhaust
pipe, of the cover, a switch is arranged on the side, close to the exhaust
pipe, of the control piece, and when gas pushes the feeler lever to abut against the switch, the control piece starts the motor. The feeler lever starting motor is pushed by gas generated by
fermentation of the
fertilizer in the fermentation tank to be started, and the
fertilizer needing to be fermented in the fermentation tank is stirred, so that the fertilizer in the fermentation tank can be fully fermented, the fermentation efficiency of the fertilizer is improved, and the labor cost is reduced.
