Automatic fuel charging device for gas producer

The utility model relates to an automatic fuel charging device for a gas producer, particularly an automatic fuel charging device for small nitrogenous fertilizer plants to make gas. The automatic fuel charging device for a gas producer comprises a motor, a speed reducer, a reciprocating feeding mechanism, a flap valve mechanism, a distributor, and the control mechanism of the distributor. An eccentric wheel installed on the output shaft of the speed reducer is hinged with one end of a rocking arm in the reciprocating feeding mechanism which is positioned on the upper part of the inside of a funnel. The lower part of the funnel is communicated with the feed nozzle of a coal containing drum via the flap valve mechanism. The lower part of the coal containing drum is provided with the distributor, and the upper part is provided with the control mechanism of the distributor which is connected with the slide bar in the control mechanism. The lower part of the distributor is communicated with a fire hole. The utility model not only can guarantee that coal is evenly put in the gas producer, but also can effectively isolate the gas producer to communicate with the atmosphere to guarantee safety production.
