Control method, device and equipment for air inlet mechanism of agricultural machine and medium

The invention relates to a control method, device and equipment for an air inlet mechanism of an agricultural machine and a medium, and belongs to the technical field of agricultural machines.The method comprises the steps that current state monitoring data of the agricultural machine are obtained, and the current state monitoring data comprise the rotating speed of an engine and the resistance of an air filter; according to the rotating speed of the engine, whether the engine is in a flameout state or not is judged; if the engine is in the non-flameout state, the working state of the electromagnetic valve is controlled according to the rotating speed of the engine and the resistance of the air filter; and when the working state of the electromagnetic valve is an open state, the air flow generated by the fan is controlled to enter the air filter through the electromagnetic valve for dust removal. The dust-proof device has the advantages that the engine is effectively protected from being damaged by dust, the
